Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a ball game in which a player is given a predetermined game value in a specific game state based on a display result of a variable display device being a predetermined display result. It is about machines.

[0002]

2. Description of the Related Art Conventionally, for example, when a variable display device provided in the center of a game board (which may be generally referred to as a special symbol display device) has a predetermined jackpot display result, a game state There were a lot of ball game machines on the market that can bring about a predetermined specific game state. However, some of these ball game machines have multiple types of jackpots in order to attract the player's interest. Of the results, when a special game state is set by a specially determined special jackpot display result, the probability that the display result will be a jackpot display result will be improved in the subsequent fluctuation of the variable display device, and the particular game state will be set at a relatively short interval. Have been proposed. Further, in such a ball game machine, the applicant of the present invention has previously disclosed Japanese Patent Application No. 4-351708 (hereinafter, referred to as prior art 1
When the display result of the variable display device during the probability improvement period becomes a special display result that is the cause of the probability improvement, it is possible to give the player satisfaction by extending the probability improvement period. I proposed a ball game machine.

However, in the above-mentioned prior art 1, as long as the special display result is displayed during the probability improving period, the probability improving period is extended for a long period of time, which causes a great damage to the game arcade. There was a problem of giving.
In order to solve such a problem, the present applicant has previously filed Japanese Patent Application No. 6-163257 (hereinafter referred to as prior art 2).
Therefore, when the cumulative number of probability improvement reaches a predetermined value, a ball game machine that can suppress the control related to the probability improvement and avoid the extension of the probability improvement period for a long time according to this is proposed.

[0004]

However, in the above-mentioned prior art 2, the cumulative number of times (predetermined value) of probability improvement is always set to a constant value in any game state, and if the probability improvement continues for a predetermined number of times, it is uniform. It was supposed to suppress the control of probability improvement. Therefore, the expectation that the probability improvement continues is limited to a predetermined number of times, and the interest in the game is halved. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cumulative number (predetermined value) for suppressing probability improvement so as to avoid extending the probability improving period for a long period of time. In a ball game machine,
It is an object of the present invention to provide a ball game machine in which the cumulative number (predetermined value) can be changed according to the game state so that the expectation that the probability is continuously improved is not lost.

[0005]

In order to achieve the above-mentioned object, in the present invention, based on the display result of the variable display device being a predetermined specific display result, a specific game state is established and a game is played. In a ball game machine that gives a predetermined game value to a player, the probability that the display result of the variable display device displays the specific display result based on the establishment of a predetermined condition that has been determined is a predetermined number of specific games thereafter. Probability improving means for improving until a state occurs, and probability improving number updating means for updating the value of the predetermined number of times when the predetermined condition is satisfied again during the probability improving period improved by the probability improving means, A determining means for determining whether or not the total number of times improved by the probability improving means is a predetermined value,
It is characterized by further comprising: suppression means for suppressing control related to probability improvement in accordance with the determination result of the determination means; and predetermined value variation control means for varying and controlling the predetermined value when a predetermined predetermined gaming state is reached. To do.

As the suppressing means, a probability improving prohibiting means for immediately prohibiting the operation of the probability improving means, a predetermined condition satisfaction prohibiting means for prohibiting the satisfaction of the predetermined condition, and a predetermined probability for suppressing the satisfaction probability of the predetermined condition. Any of the condition satisfaction suppressing means can be adopted.

As the predetermined game state, the display result of the variable display device is in a specific display state when the predetermined condition is satisfied, or the game history until the predetermined condition is satisfied is a specific state. Can be

[0008]

Probability improving means for improving the probability that the display result of the variable display device displays the specific display result based on the establishment of a predetermined condition, until a predetermined number of specific game states occur thereafter. When the predetermined condition is satisfied again during the probability improving period improved by the probability improving unit, the probability improving number updating unit that updates the value of the predetermined number of times and the cumulative total of the number of times improved by the probability improving unit are the predetermined value. Determination means for determining whether or not, a suppression means for suppressing control relating to probability improvement according to the determination result of the determination means, and a predetermined value variation control means for varying and controlling a predetermined value when a predetermined game state is reached. Since the above is provided, it is possible to avoid extending the probability improvement period for a long period of time, and it is possible to prevent the hole side from being greatly damaged. In addition, the cumulative number of times (predetermined value) for suppressing probability improvement provided in order to avoid the extension of the probability improving period over such a long time can be changed according to the gaming state, so that the probability is improved. It is possible to improve the enjoyment of the game without losing the continuous expectation.

Specifically, each of the changeover switches 43 and 44 is configured to increase and change the set value and the mode number by 1 each time it is pressed, and the mode number is designated by operating the mode changeover switch 44. The set value corresponding to the selected mode number is set by operating the set value selector switch 43. After that, when the setting value registration for each mode by the respective change-over switches 43 and 44 is completed, the setting memory switch 42 is switched from the memory changing state (M) to the setting state (S) to store the setting of the mode setting value. To be completed. Each of the above-mentioned indicators 45 and 46 lights and displays a numerical value when the setting memory switch 42 is in the set state (S), and blinks the numerical value when the setting memory switch 42 is in the memory change state (M). By doing so, the switching state of the setting memory switch 42 can be visually confirmed. When the mode changeover switch 44 is pressed while the setting memory switch 42 is in the set state (S), the mode setting values currently set and stored are sequentially displayed on the respective display units 45 and 46, so that the mode is changed.

In addition, the mode 5 sets the probability of displaying the probability variation pattern in the first big hit, that is, the probability variation inrush rate, and the mode 6 displays the probability variation pattern in the big hit during the probability change,
That is, the probability variation continuation rate is set. Further, the mode 7 sets the normal symbol shortening probability, and the mode 8 sets the normal symbol time saving upper limit number, respectively.

The structure of the game board 1 including the variable winning ball device 10 and the variable display device 30 has been described above.
Those game devices provided on the game board 1 are controlled by the game control circuit shown in FIGS. 6 and 7. 6 and 7 are circuit diagrams showing a block configuration of the game control circuit, which is controlled by a basic circuit 50 including an MPU, ROM, RAM, and an input / output circuit. Then, the basic circuit 50
Includes a counter 50a for controlling the period continued with a high probability, and the basic circuit 50 has a prize winning ball detector 14a, 14b, a specific ball detector 13, and a starter via the input circuit 51. Winning ball detector 8 ・ 9, passing ball detector 22
The detection signals from the a / 22b, the setting memory switch 42, and the change-over switches 43/44 are input, and the address decode circuit 52 provides a chip select signal to the basic circuit 50. Also, when the power is turned on, the initial reset circuit 53
From the above, a reset signal is given to the basic circuit 50, and the regular reset signal is given from the periodic reset circuit 54 to the basic circuit 50 every predetermined time.

On the other hand, the basic circuit 50 provides control signals to the following devices and circuits. That is, the voice generation circuit 5
An audio signal is given to the speaker 41 via 5. Also,

Further, the basic circuit 50 outputs effective start information, big hit information, and probability variation information to the outside such as a hall computer via the information output circuit 60. In addition, the above devices and circuits include
Electric power having various voltages is supplied from the power supply circuit 61.

An example of a specific operation of the game control circuit described above will be described with reference to the time charts and explanatory diagrams shown in FIGS. 8 to 22. First, with reference to FIG. 8 to FIG. 11, the operation of the variable display 35 for normal symbols will be described. In FIG. 8, when a hitting ball passes through the passage openings 21a and 21b, the passing ball detectors 22a and 22b are turned on, and the passing signal T1 is derived, one value from random 4 is obtained when the passing signal T1 rises. To be extracted. Random 4
As shown in FIG. 9, is a random number for determining whether or not it is a winning symbol, and as shown in FIG. 19 described later, fifteen numerical values of “0 to 14” are incremented every interruption process. It is fluctuating. Further, after deriving the passing signal T1, 0.002
The value of the random 4 stored when the second has elapsed is read out, and one value is extracted from the random 5 when the read value of the random 4 does not hit. As shown in FIG. 19, this random 5 is such that 0 and 1 change for each interrupt process and for each interrupt process residual time, and when 0 is extracted, the variable display for normal symbols at the time of stop 35
"3" is displayed on the screen, and when 1 is extracted, "F"
Is displayed.

Thus, when the numerical value extracted from the random 4 is, for example, "1", it is determined to be a hit, and "7" which is the specific display result is displayed on the variable display 35 for normal symbols. On the other hand, when the numerical value extracted from the random 4 is other than the above, it is determined to be out, and the above-mentioned symbol corresponding to the value of the random 5 extracted at that time is displayed on the normal symbol variable display 35. In the above-described determination of the hit-off, when the probability is low and when the probability is high, when the value extracted from the random 4 is any value of "1 to 10", it is determined to be a hit. ing. Therefore,
The probability of winning at low probability is 1/15, while the probability of winning at high probability is 10/1.
It will be 5 and will be changed 10 times.

As described above, when the passage signal T1 is derived, it is determined whether or not the symbol displayed on the normal symbol variable display 35 is hit, and the symbol displayed at the stop is also determined. After the determination is completed (in the present embodiment, 0.002 seconds after the passage signal T1 is derived), the fluctuation of the normal symbol variable display 35 is started. Then
The fluctuation time at the low probability is set to be relatively long (25.000 seconds), and the fluctuation time at the high probability is set to be relatively short (7,000 seconds). this is,
When the probability is high, the hit is made early, the electric start winning opening 6 is opened, and a large number of starting winning balls are generated.
It is intended that the fluctuations of 8a to 38c are continuously performed, and this is to attract the player's interest at a high probability.

As described above, the variable display 3 for ordinary symbols
The game after 5 stopped changing display is shown in FIG. 10 and FIG.
Shown in. Therefore, referring to FIG. 10, the case of deviation will be described first. After the variable display for the normal symbol variable display 35 is stopped, a small time (0 (.002 seconds),
When there is a passing memory, the variable display 35 for normal symbols starts to change again. Next, referring to FIG. 11, the case of a hit will be described. After a fixed time (0.500 seconds) has elapsed after the variable display of the normal symbol variable display 35 is stopped, the electric start winning opening 6 is fixed. Time (3.000
Seconds) will be released. However, when three winning balls are accepted during the opening, the opening is stopped even before the predetermined time has passed. Then, after finishing the opening of the electric start winning opening 6, a small time (0.00
After 2 seconds), if there is a passing memory,
The variable display for normal symbols 35 starts to change.

When the ball hitting the electric start winning opening 6 opened as described above, the variable display portions 38a to 38c start to change. The operation will be described with reference to FIGS. 12 and 13. . However, in FIG. 13, each set value of mode 1 and mode 2 is "2" by the mode set value storage means.
It shows the case where it is set to. First, in FIG. 12, when a hit ball is won in the starting winning opening 5 and the electric starting winning opening 6 and the starting winning ball detectors 8 and 9 are turned on, and the starting signal S1 is derived, the rising of the starting signal S1. Sometimes one value is extracted from each of Random 1 and Random 2 or Random 3. Random 1 is a random number for determining whether or not it is a big hit symbol as shown in FIG. 13, and as shown in FIG. 19 which will be described later, 248 ways of “0 to 247” for each interrupt process after power-on. Random 2 is a random number for determining the arrangement pattern of the big hit symbols, and it is "0 to 2" for each interrupt process after power-on and for each extra time of the interrupt process.
24 ”numerical values of“ 3 ”are fluctuating moment by moment. Random 3 is a random number for determining the display pattern of the out-of-design, and is set for each interrupt process after turning on the power and for each extra time of the interrupt process. The number of 5832 kinds of "0-5831" is changing every moment. In addition, after 0.130 seconds have passed after the start signal S1 was derived, the value stored in Random 1 is read out, and further, the values of Random 2 and 3 stored when 0.132 seconds have passed are read out from Random 6 One value is extracted. The random number 6 is a random number for determining the design displayed on the decorative design 34, and is not directly related to the game content.

Therefore, when the numerical value extracted from the random 1 is, for example, "128", it is judged as a big hit, and the symbol arrangement pattern corresponding to the value of the random 2 extracted at that time (FIGS. 17 and 18 which will be described later). Is displayed on the variable display portions 38a to 38c. On the other hand, random 1
When the numerical value extracted from is other than the above, it is determined to be out of order, and the symbol array pattern corresponding to the value of the random 3 extracted at that time is displayed on the variable display portions 38a to 38c. However, if it happens to coincide with the jackpot pattern, "1" is added to the random 3 to display it as a deviating symbol. The above-mentioned determination of the big hit miss is a case of a low probability, and at a high probability, when the value extracted from the random 1 is any value of "128 to 137", it is judged as a big hit. Has become. Therefore, the probability of a big hit at low probability is 1/248
On the other hand, the probability of a big hit at the time of high probability is 10/248, which means that the probability is changed to 10 times.

As described above, when the start signal S1 is derived, it is determined whether or not the symbols displayed on the variable display portions 38a to 38c are hit, and the symbols displayed at the time of stop are also determined. After the end of the above (in the present embodiment, 0.156 seconds to 0.164 seconds have elapsed since the start signal S1 was derived), the variable display portions 38a to 38c start changing with a slight time lag. Then, the left variable display section 38
In the variable display of a, the basic time (5.100 seconds) is set to a predetermined variable speed and fluctuates, and when the basic time elapses, it is stopped when the variable time for one symbol elapses. Similarly, in the variable display of the right variable display portion 38c, the variable display is changed at the predetermined changing speed for the same basic time (5.100 seconds) as described above, and when the basic time elapses,
It is stopped when the variation time for 6 symbols has passed.

On the other hand, in the variable display of the medium variable display portion 38b, when the stop symbol on the hit line displayed on the variable display portions 38a and 38c which has already stopped is not the big hit symbol (when it is not in the reach state) and the big hit symbol. The display is variably displayed in a different mode from when (in the reach state). Therefore, first, the variable display when not in the reach state will be described.
During the second), the speed fluctuates by being set to a predetermined fluctuation speed, and when the basic time elapses, it is stopped when the fluctuation time for 11 symbols elapses.

Next, the variable display in the reach state will be described. During the same basic time as above (5.100 seconds), it is set at a predetermined fluctuation speed and fluctuates, and when the basic time elapses, it is stopped when the fluctuation time of 49 to 66 symbols elapses. However, the changing speed of the 49 to 66 symbols is set to a slightly slow changing speed.

The variable display portions 38a to 38 are arranged as described above.
The game after c stops changing display is shown in FIG. 14 to FIG.
Shown in. Therefore, referring to FIG. 16, the case of disconnection will be described first.
In c, the value stored in Random 1 is read when a fixed time (1.200 seconds) elapses after the variable display of the medium variable display portion 38b, which last stops changing, is stopped. When the second has elapsed, the stored values of Random 2 and 3 are read out, and one value is extracted from Random 6. Then, after that, 0.156 seconds or 0.16
After 4 seconds have elapsed, the left variable display section 38a first starts changing, the middle variable display section 38b starts changing slightly later, and the right variable display section 38c also starts changing slightly later (not shown). To do.

Next, referring to FIG. 15, the case of a big hit will be described. After a fixed time (5.650 seconds) has elapsed after the variable display of the three variable display portions 38a to 38c has stopped, the variable winning a prize is obtained. The ball device 10 has a relatively long time (29.
It is opened for 500 seconds. However, when the number of winning balls reaches 10 before the elapse of the certain period of time, it is closed at that time. Then, after this opening is completed, a fixed time (2.000 seconds) is set as the accessory continuous operation device operation valid time, and the winning balls received by the opening / closing plate 11 after the opening of the variable winning ball device 10 is completed. Is a specific ball detector 13
When it is turned on, it is recognized as valid and the continuation right is generated. Then, when the continuation right is generated, the variable winning ball device 10 is controlled to be opened again after the effective working time of the accessory continuous operation device has elapsed.

By the way, the mode in which the symbols displayed when the variable display portions 38a to 38c are stopped is a combination of big hit symbols is as described above when the three hit lines shown in FIG. 18 are taken into consideration. There are 24 combinations, and as shown in FIG. 17, 24 combinations are made to correspond to random 2 of “0 to 23”. And among the jackpot combination modes, “7 (CHANSE)” and “BI
If the special game state of "G" special probability (probability variation pattern) is in the specific game state (any winning line), the variable display for normal symbol 35 and the variable display portions 38a-38c probability of displaying the specific display result Is controlled to improve. In the present embodiment, the setting values of modes 5, 6, and 7 are set to "2" by the mode setting storage means. That is, the probability variation rush rate, the probability variation continuation rate, and the normal symbol shortening probability are set to "6/24", respectively. Therefore, 6 random numbers of "18-23" out of the 24 random numbers of "0-23" described above are set as random numbers for probability variation, and "7 (CHANSE)" and "BI" are set.
The jackpot design of "G" is used as a probability variation design. Further, in the present embodiment, the probability variation inrush rate, the probability variation continuation rate, and the normal symbol shortening probability are set to the same value, but the present invention is not limited to this, and it is possible to individually set different values. is there.

Next, the main routine by the game control circuit will be described with reference to FIGS. FIG.
First, in step 10 (hereinafter abbreviated as S10), a stack set process for designating an address to be a stack area in the memory area is executed, and then S2.
At 0, it is determined whether or not there is a RAM error (RAM normal). If normal, various information data is I / O at S30.
After that, in S40, it is determined whether or not there is a warning due to an abnormality in various switches, and if there is no abnormality, a special symbol process process and a normal symbol process process are executed in S50. In the special symbol process processing, the variation control of the variable display portions 38a to 38c and the opening / closing control of the variable winning ball device 10 in the big hit are performed. Also,
In the normal symbol process process, the variable display control of the normal symbol variable display device 35 and the opening / closing control of the electric start winning opening 6 at the time of hitting are performed. After the completion of the processing of S50 and when it is determined that there is an abnormality in S40,
In S60, a process of accepting input signals from various switches is performed, then in S70, random 1/4 is created (update process), and in S80, random 2.3.5 / 6 is created. When it is determined in S20 that there is a RAM error, initialization is performed in S120, and then the above-described processing of S70 and S80 is executed. In this way, all the random numbers are updated each time the main routine is executed once (every time an interrupt is issued). Therefore, when the main routine is updated only within the extra time of the main routine, the extra time is updated. Although there is a drawback that the update process is not performed when there is no random number, the random number update process is certainly performed. Particularly, in the present embodiment, the important random 2 is surely updated, so that the same big hit symbol arrangement pattern is continuously prevented from occurring as much as possible.

Next, in S90, the count value of an interrupt counter (not shown) (reset each time counting 0 to 7) is determined, and when the value of the interrupt counter is "0", a symbol LED (for example, , Numerical display 16) control and sound data output are executed, and when the value of the interrupt counter is "1 to 7," output data table selection control and decorative LED / lamp display control are executed in S130. . Thereafter, the random 2, 3, 5, and 6 creation process (update process) is executed in S110 until the next interrupt signal (periodic reset signal) is input.

By the way, the probability variation process in the special symbol process process of S50, that is, the update process of the probability variation counter of the probability variation will be described with reference to FIG. 20. First, in S200, it is determined whether or not a big hit. If it is not a big hit, the subroutine is ended, and if it is a big hit, it is processed with a low probability in S210, and then it is determined in S230 whether or not the big hit is 7 chances. The value of the fluctuation counter C1 is set to "2" to end the subroutine, and if there is no 7 chance, S2
In 40, it is determined whether or not the big hit is BIG. If it is BIG, the value of the probability variation counter C1 is set to "1" in S260, the subroutine is terminated, and if it is not BIG, the probability variation counter C1 is updated. End the subroutine without. When the value of the probability variation counter C1 is set to "2" in S250 described above, as shown in FIG.
Since the high-probability state is made to appear twice, as a result, at least three big hit game states appear at relatively short time intervals. Further, in S260, the probability variation counter C1
When the value of is set to "1", as shown in FIG. 22B, the high-probability state appears once, and as a result, at least two jackpot gaming states are relatively short time intervals. Will appear in. In addition, the processing of S210 described above is
It need not always be performed and may be omitted. Also, S2
Between S10 and S230, the determination process S for performing the process of S230 and below only when the value of the probability variation counter C1 is "0".
220 may be inserted. By inserting such a process, the probability improving period is extended only when the last big hit of the probability improving period is caused by the probability variation pattern.

In this way, a big hit occurs, a probability variation pattern that the big hit improves the probability (special big hit display result)
Since the value of the probability variation counter C1 is constantly varied, the phenomenon that the probability improvement period is extended indefinitely occurs as long as the probability variation pattern is displayed during the probability improvement period. In order to eliminate such an unlimited extension, a process of regulating the probability variation is performed as described in the flow chart of FIG. Therefore, referring to FIG. 21, it is determined whether or not the big hit has ended in S300, and when it has not ended, the subroutine is ended without performing the following processing, and when the big hit is ended,
In S310, it is determined whether or not the value of the probability variation counter C1 is "1 or more", and it is not "1 or more" (that is,
When it is determined to be "0"), the subroutine is ended without performing the following processing, and when it is determined to be "1 or more", the following processing is executed to maintain a high probability. First, in S320, "1" is added to the value of the probability variation regulation counter C2, and then in S330, it is determined whether or not the value of the probability variation regulation counter C2 is "N or more". It should be noted that the numerical value N that is the criterion for the probability fluctuation regulation counter C2
Is the maximum number of probability changes described in detail later. Then, when it is determined that the value of the probability variation regulation counter C2 is not “N or more”, it is determined that the value is still within the allowable cumulative range, and “1” is subtracted from the value of the probability variation counter C1 in S340. , S350 is set to a high probability and the subroutine is ended. On the other hand, the probability fluctuation regulation counter C
When it is determined that the value of 2 is "N or more", the value of the probability variation regulation counter C2 is reset to "0" in S360 because it is determined that the allowable cumulative range is exceeded.
In step S370, the value of the probability variation counter C1 is also reset to "0" and the subroutine ends. When the value of the probability variation counter C1 is set to "0" in S370, the variable display units 38a to 38c perform the variation operation with the low probability without being changed to the high probability in the subsequent processing.
The probability improvement period will not be extended.

FIG. 22C shows a specific example of the operation of FIG. 21 described above. In this case, it is assumed that the probability variation upper limit number N is set to 6. In FIG. 22 (C), it is a time chart when the big hits continuously occur at "7 chances" of the probability variation pattern, and when the big hits continuously occur at "7 chances" in this way, ,
Although the value of the probability fluctuation counter C1 is always set to "2" and the probability improvement period is extended over a long period of time, the value of the probability fluctuation regulation counter C2 is "5", that is, the big hit continues. If it continues for 5 times, the value of the probability variation counter C1 is reset to "0".
The processing of 0 is not executed, and the probability returns to low immediately. Therefore, the big hit game state is suppressed in a short period with respect to the subsequent fluctuation results of the variable display portions 38a to 38c.
Therefore, it does not cause much damage to the game arcade. In addition, in FIG. 22C, the case where even the first big hit after the value of the probability variation counter C1 is reset to “0” happens to occur at “7 chances” is shown.
In this case, the probability variation regulation counter C2 newly starts counting.

In the above-described embodiment, as a means for suppressing the probability increase, when the value of the probability fluctuation regulation counter C2 reaches a predetermined cumulative number, the probability fluctuation counter C1 is reset to "0" and the probability immediately increases. Although the extension of the improvement period is prohibited, the probability improvement may be suppressed by prohibiting or suppressing the appearance of the probability variation pattern that causes the probability improvement. As such an example, the processing shown in FIGS. 23 and 24 may be performed. FIG. 23 is a flow chart for surely preventing the appearance of the probability variation pattern, and FIG. 24 is
It is a flow diagram for suppressing the appearance of a probability variation pattern. First, referring to FIG. 23, the steps S80 and S11 will be described.
In the process of creating Random 2 of 0, the process of adding “1” to Random 2 is performed in S400, and then S41 is performed.
At 0, it is determined whether or not the value of the probability variation regulation counter C2 is "N or more". If "N or more", it is determined that the cumulative count value exceeds the planned value, and the current value of the random 2 at 2 is determined in S420. If the value is "18 or more", the value of Random 2 is smaller than "18" (if it is not a probability variation pattern), the subroutine is ended as it is, and the value of Random 2 is "18 or more". (In the case of a probability variation pattern), S430
Clears the value of random 2 and sets it to "0" to end the subroutine. Therefore, when the cumulative count value exceeds the planned value, the value of random 2 is a probability variation pattern (Fig. 1
Since it does not have a numerical value corresponding to (7), it is possible to completely prohibit the occurrence of the big hit due to the probability variation pattern that causes the probability improvement period to be extended. On the other hand, the above S410
When it is determined that the value of the probability variation regulation counter C2 is smaller than "N", the cumulative count value has not yet exceeded the planned value, so the value of Random 2 is "24 or more" in S440.
If it is not "24 or more", the subroutine is finished as it is, and the value of the random 2 is "24 or more".
In this case, the value of Random 2 is cleared and set to "0" in S450, and the subroutine is ended. Thus, in the case of this processing, when the value of the probability variation counter C1 remains, the value is not reset to "0", and the jackpot gaming state due to the jackpot symbol other than the probability variation symbol is a short period thereafter. Therefore, the player's dissatisfaction can be lessened as compared with the case of the processing of FIG. It should be noted that instead of the clearing process in S430, S5 described below is performed.
Random 2 may be rewritten to a numerical value corresponding to a symbol other than the probability variation symbol like 30.

Next, the operation of suppressing the appearance of the probability variation pattern will be described with reference to FIG. 24. In S500, it is determined whether or not it is a big hit. If it is not a big hit, the subroutine is terminated without executing the following processing. If it's a big hit,
In S510, it is determined whether or not the value of Random 2 is one of "18, 20, 21, 23" corresponding to some probability variation symbols, and if not, the subroutine below is not executed. Ends, and if any of the values, S
At 520, it is judged if the value of the probability variation regulation counter C2 is "N or more". If it is not "N or more", the cumulative count value has not exceeded the planned value, so the subroutine is terminated without executing the following processing. If "N or more", the cumulative count value does not exceed the planned value. Because it exceeds, S530
Then, the value of the random 2 "18, 20, 21, 23" is rewritten to "6, 8, 12, 14" which does not correspond to the probability variation pattern, and the subroutine is finished. Thus, FIG.
When the cumulative count value exceeds the planned value, the processing shown in 4
Since the probability of the big hit due to the probability variation pattern is lowered (not completely out), it is possible to suppress the extension of the probability improvement period. In the example of suppressing the appearance of the probability variation pattern in FIG. 23 described above, when the value of Random 2 corresponding to the probability variation pattern is extracted as in this example, the random value may be rewritten. This example may be performed by a method of changing the range designation of random 2 as in the example described above.

Next, the process of setting the above-described probability variation upper limit number N will be described with reference to FIG. In FIG. 25, first,
Whether the power is on or not is determined (S600). If the power is on, the probability variation upper limit number X set by the mode 3 setting value stored by the mode setting value storage means is set as the probability variation upper limit number N. (S610). Then S
At 620, it is determined whether or not it is a big hit, and when a big hit occurs, then it is determined whether or not the big hit symbol is a probability variation symbol (S630). If it is a probability variation symbol in S630, then it is determined whether or not the probability variation symbol is "7 chances" (S640). Probably strange pattern is "7 chance" in S640
When it is determined that, the probability variation upper limit number X plus "3" is set as the probability variation upper limit number N (S65).
0), the above setting process is completed. On the other hand, when it is determined that the probability variation pattern is other than "7 chances" in S640, that is, "BIG", it is determined whether or not the big hit is a probability variation (S660). Then, if it is determined in S660 that the jackpot is a big hit during probability variation, the upper limit number X set by the mode setting value storage means is set to the probability variation upper limit number N (S
670), and the above setting process ends. The above-described setting process of the probability variation upper limit number N is related to the probability variation of the special symbol, and the probability variation of the normal symbol is the above S.
25 is executed assuming that the number of times X set as the probability variation upper limit number N in 610 or S670 is based on the set value of mode 4 set and stored by the mode set value storage means.

As described above, in this embodiment, the probability variation upper limit number for suppressing the probability improvement is provided to avoid the extension of the probability improvement period for a long time. Since the predetermined value to be set can be selected and set in advance to any one of a plurality of levels by the mode setting value storage means (predetermined value setting means), it is possible to meet the needs of the hole side of the ball game machine. It becomes possible to provide.
Further, the predetermined value forming the probability variation upper limit number is the mode when the big hit symbol during the probability improvement period is the probability variation symbol of "7 chances" in each step (predetermined value variation control means) of S640 and S650 of FIG. 25 described above. "3" is added to the set value X by the set value storage means. That is, in the present embodiment, the probability is improved by increasing the cumulative number of times (predetermined value) for suppressing the probability improvement in accordance with a predetermined game state (in the embodiment, a big hit occurs with a probability variation pattern of "7 chances"). It does not lose the sense of continuous expectation, which in turn improves the interest of the game.

The above-mentioned predetermined value fluctuation control means is not limited to the one that increases the cumulative number of times (predetermined value) for suppressing the probability improvement in accordance with the predetermined game state, but it decreases or in the predetermined game state. May increase and decrease in other predetermined game states. Further, the process of increasing the cumulative number of times (predetermined value) by the predetermined value variation control means is not limited to S640 and S650 of FIG. 25. For example, the process of setting the upper limit number N of probability variation shown in the flowchart of FIG. It may be processing.

The setting process of the probability variation upper limit number N of FIG. 26 will be described below. In FIG. 26, first, it is determined whether or not the power is on (S700). If the power is on, the mode 3 set and stored by the mode set value storage means is stored.
The probability variation upper limit number X depending on the setting value of (or mode 4) is set as the probability variation upper limit number N (S710). Then S
At 720, it is determined whether or not it is a big hit, and when a big hit occurs, it is then determined whether or not the big hit symbol is a probability variation symbol (S730). When it is a probability variation pattern in S730, it is then determined whether or not the big hit is a probability variation (S740). If it is determined in S740 that it is a big hit during probability variation, the process directly proceeds to S760, whereas if it is determined that it is not a big hit during probability variation, the upper limit number X set in the mode setting value storage means is set to the upper limit number N in probability variation (S750), and thereafter. The process moves to S760. Then, in S760, it is determined whether or not the probability variation pattern is "7 chances". When it is determined that the probability variation pattern is "7 chances", "1" is added to the probability variation upper limit number N (S770), The above setting process ends. Thus, S760 and S770 of FIG.
In each step (predetermined value variation control means), the probability variation upper limit number N is incremented by 1 each time a big hit occurs with the probability variation pattern of "7 chances". On the other hand, as shown in FIG.
In the setting process of 5, in the case of a big hit with the probability variation pattern of "7 chances", the probability variation upper limit number N is set to increase from the set value X to "X + 3", but after that, during the probability variation, a big hit with the probability variation pattern of "7 chances" However, the maximum number of probability changes is not increased. That is, in the setting process of FIG. 26, since the probability variation upper limit number N is always increased every time a predetermined game state (in the embodiment, a big hit occurs with a probability variation pattern of “7 chances”), the probability is extremely high. Although small, it is possible to make the player have an expectation that the probability improvement can be continued semipermanently.

In this embodiment, the condition (predetermined game state) in which the predetermined value fluctuates by the predetermined value fluctuation control means is set to the time when the big hit occurs with the probability variation pattern of "7 chances". Is shown below (1)
It is possible to apply each condition of (14). Further, in the following description, a specific example is shown for each condition, and the effect when the condition is applied is described.

(1) Conditions depending on the type of big hit symbol For example, if the probability variation symbol "7 chances" is hit, the probability variation upper limit number is changed from 6 times in the normal time to 9 times (this embodiment). In this case, the possibility of a large number of payouts changing depending on the type of symbol makes it possible to provide a gaming machine having a higher gambling property than the conventional one having a fixed upper limit value.

(2) Conditions based on the total number of big hits other than the probability variation pattern For example, if the number of big hits other than the probability variation pattern reaches a predetermined number of 5 from the last big hit of the probability variation pattern to the present big hit, the probability variation upper limit number of the normal time Change from 3 times to 6 times. In this case, even if the regular pattern big hits are continuous, if there is a big hit with the probability variation pattern, there is an expectation of one-shot reversal.

(3) Conditions based on the number of continuation times of the previous probability variation hits For example, if the number of continuations is 2 times or less when a big hit is made with the previous probability variation pattern, the probability variation upper limit number of this time is 3 to 6 times in the normal time. Change to. In this case, even if the number of balls thrown out last time is small, the upper limit of the number of times of continuation is increased so that the player's willingness to play is not impaired if it hits with the next probability change.

(4) Conditions when the big hit of the probability variation pattern is the first hit from the power-on For example, when the big hit with the probability variation pattern is made in the morning, the probability variation upper limit number is changed from 3 times in the normal time to 6 times. in this case,
The number of customers at the time of opening the store will be high.

(5) Condition based on the number of starting memories at the time of big hit For example, if the number of starting memories at the time of a big hit with a probability variation pattern is 3 or more, the probability variation upper limit number is changed from 3 times at the normal time to 6 times. In this case, it is possible to prevent the player from stopping at the time of reaching.

(6) Conditions based on the number of starting times For example, the number of starting times from the previous big hit to the present probability variation hit is counted, and if the count number is 1000 times or more, the probability variation upper limit number is changed from 3 times in normal time to 6 times. Change to times. In this case, it is possible to give a sense of expectation of one-shot reversal even if the investment of the player increases.

(7) Condition by reach frequency For example, the reach frequency is counted from the last big hit to the current probability variation hit, and if the count number is 50 times or more, the probability variation upper limit number is changed from 3 times in normal time to 6 times. change. In this case, it is possible to give a sense of expectation of one-shot reversal even if the investment of the player increases.

(8) Condition by the number of difference balls For example, if the number of difference balls lost by the player from the last big hit to the current probability change hit is 10,000 or more, the upper limit number of probability changes is 3 to 6 times in the normal case. Change to. In this case, it is possible to give a sense of expectation of one-shot reversal even if the investment of the player increases. In addition, the number of difference balls can be calculated by subtracting the number of hit balls from the number of hit balls,
The upper limit number of probability changes may be changed only by the number of balls or only the number of balls hit.

(9) Conditions depending on the time required from the previous big hit to the present big hit For example, if the time required from the last big hit to the present probability change is 2 hours or more, the upper limit number of the probability change is from 3 to 6 in the normal time. Change to times. In this case, it is possible to give a sense of expectation of one-shot reversal even if the investment of the player increases.

(10) Condition when a predetermined time has passed from power-on, for example, if a big hit of the probability variation pattern this time occurs within 1 hour before the closing time, the probability variation upper limit number is changed from 4 times in the normal time to 2 times. . In this case, since the number of players whose probability is changing at the time of closing the store is reduced, it is easy to close the store according to the closing time.

(11) Conditions when a certain probability (super reach) causes a certainty variation big hit For example, when a certain amount of certainty variation big hits occurs from super reach, the upper limit number of certainty variation is changed from three times in the normal case to six times. In this case, since the expectation varies depending on the type of reach, the game playability increases.

(12) Conditions for winning in a predetermined winning opening For example, by winning or passing through a predetermined winning opening, the upper limit number of probabilistic changes is changed from 3 times in normal times to 6 times. In this case, the game property is improved by mixing the game property in the symbol variation and the game property in the ball.

(13) Condition by hitting a specific line of a plurality of hit lines For example, when the probability variation symbols are aligned on the center line of the five hit lines, the probability variation upper limit number is changed from 6 to 9 in the normal time. Change to times. In this case, since the possibility of a large number of payouts changing depending on the winning line, it is possible to provide a gaming machine having a higher gambling property than the conventional one having a fixed upper limit value.

(14) Conditions depending on the number of hit lines out of a plurality of hit lines For example, two big lines of the five big hit lines are lined up with big hit symbols and at least one big hit symbol of the two big hit symbols is changed. If it is a symbol, the probability variation upper limit number is changed from 6 times in normal time to 9 times. In this case, since the possibility of a large number of payouts changes depending on the number of lines per hit, it is possible to provide a gaming machine having a higher gambling property than the conventional one having a fixed upper limit value.

Next, a display image on the LCD display 38 related to the probability change will be described with reference to FIGS. 27 (A) to (D). First, a big hit occurs due to the probability variation pattern (big hit pattern), and if the probability variation continues until a specific number of times of the specific game state occurs, immediately before the end of each specific game state except the end of the final specific game state. Displays the display image a shown in FIG. This display image a displays the actual continuation number display unit 62 that displays the number of times that the probability variation is actually continued subsequently, and the upper limit number of probability variation continuations that can be updated by hitting again with the probability variation pattern during the probability variation. The maximum continuation number display section 63 is configured to be superimposed and displayed on the image of the big hit symbol. The display image a shown in FIG. 27A exemplifies an image displayed immediately before the first specific game state ends after the big hit due to the probability variation pattern of “7 chances” occurs. Therefore, the character display of "2 more times" is displayed on the substantial continuation number display section 62, and the character display of "6 more times maximum continuation" is displayed on the maximum continuation number display section 63. In addition, immediately before the end of the final specific game state, which is the upper limit number of probability variation continuation, as shown in FIG. 27B, a display image b made up of the characters “Give up! This is the probability variation is over” is displayed. To be done.
Further, each time the upper limit value of the probability variation continuation number is updated, “the upper limit of the probability variation is 3 as shown in FIG. 27D.
The display image d consisting of the character "I have been set for the first time" is displayed.

The display form and the display timing of each of the display images a, b, d relating to the above-mentioned probability change are not particularly limited. For example, instead of (or in combination with) the display image a, the display image c of FIG. 27C is constantly displayed during the probability variation period, so that it is possible to notify the player of the probability variation continuation frequency. This display image c is provided with a symbol display portion 64 which is formed by reducing the display area of each of the variable display portions 38a to 38c on the upper side thereof, while the lower portion of the display image c displays the number of continuation of the certain variation with a band graph 66. A continuous number display unit 65 is provided. Then, the display image c displays the variation of the special symbol as usual on the symbol display unit 64, while displaying the number of executions of the probability variation continuation by the increase display of the band graph 66 on the probability variation continuation number display unit 65. .

Further, in the above-described embodiment, as a game content of the pachinko gaming machine having the variable display device (LCD display 38), when the display result of the variable display device becomes a combination of the big hit symbols, the specific game state is set. Then, the variable winning ball device 10 is immediately opened a predetermined number of times (so-called digital pachinko game machine), but a right generation game state which is a kind of a specific game state is generated based on the display result of the variable display device. The variable winning ball device is opened for a predetermined period by winning the starting winning opening during the continuation of the right generation game state, and such opening is performed a predetermined number of times on the condition that the starting winning opening receives the winning ball. It may be a pachinko game machine that has repeated game contents (so-called property). Such an embodiment will be briefly described with reference to FIGS. 28 to 30. FIG. 28 is a front view of a game board provided with a game device for implementing other game contents, and FIG.
9 is a perspective view showing the internal structure of the special variable winning ball device provided in the center of the game board, FIG. 30 is the front of the main part of the game board equipped with a special variable winning ball device according to another structure It is a figure.

In FIG. 28, the inside of a guide rail 72 provided in a substantially circular shape of the game board 71 is configured as a game area 73, and a special variable winning ball device 90 is arranged in the center of the game area 73. . Special variable winning ball device 90
Is a plurality (two) of variable display devices 91a and 91b that form a variable display device, a specific winning area 102, and a pair of ball receiving members 104a and 104b that form a variable winning ball device.
The winning balls led to the special variable winning ball device 90 in relation to the display result of the variable display devices 91a and 91b becoming the predetermined specific display result are guided to the specific winning area 102 and are not shown. When the specific winning ball detector is turned on, a right generation game state, which is a kind of the specific game state, can be generated. The configuration of the special variable winning ball device 90 will be described later in detail.

In the game area 73, a plurality of winning holes 7
4.78.80.83a.83b.84 (This 84 is
87a to 87c, windmill lamps 88a and 88b with built-in lamps, windmills (no reference number), side lamps (no reference number), and outlets 8
9 and obstacle nails (no reference number) are provided respectively. First, among the plurality of winning openings, the winning opening 74 is a combination of a winning opening 77 of a win type and a winning opening having a pair of ball receiving members 75 on one mounting plate above the special variable winning ball device 90. The lower ball receiving member 75 is opened and closed by a solenoid 76, and a winning opening 77 located in an upper position in a closed state prevents the winning of a hit ball. It has become. By the way, the ball receiving member 75, when the hitting ball passes through the passage opening device 84, which will be described later in detail, and the variable display devices 91a and 91b provided in the special variable winning ball device 90 give a predetermined specific display result. , Is opened for a predetermined time (for example, 5.9 seconds), and the winning balls received during the opening are guided to the special variable winning ball device 90. However, during the continuation of the right generation game state, even if the variable display devices 91a and 91b have a predetermined specific display result, the opening time of the ball receiving member 75 is extremely short (for example, 0.5 seconds). Controlled to be.

The winning opening 80 arranged on the left side of the special variable winning ball device 90 is called a starting winning opening 80, and is provided with a rotating body 81 which is rotated by a motor (not shown) at a predetermined cycle. ing. In addition, the rotating body 8
1, a ball receiving portion 82 for receiving one ball is formed,
The winning balls received by the ball receiving portion 82 are guided to the back surface of the game board 71 and detected by a starting winning ball detector (not shown). Then, in the start-up winning opening 80 with the rotating body configured as described above, since the rotating body 81 is normally controlled to rotate at a relatively slow cycle (for example, 2 rpm), the starting winning opening in the normal gaming state. It suppresses that the payout rate based on the winning of 80 hits is unnecessarily high. On the other hand, in the right generation game state, the cycle of the rotating body 81 is relatively fast (for example, 6
rpm), and the ball receiving portion 8 of the rotating body 81 is controlled.
When the prize winning ball received in 2 is guided to the back surface of the game board 1 and the start prize winning ball detector is turned on, the ball receiving member 1 constituting the variable winning ball device provided in the special variable winning ball device 90.
04a and 104b are opened until a fixed time (for example, 9.5 seconds) elapses, or until a predetermined number (for example, 10) of winning balls are generated until the fixed time passes. The rotation cycle of the rotating body 81 is the same as the ball receiving member 104.
It is set to be almost the same as the opening time of a104b.

Here, the contents of the game in the right generation game state will be briefly described. As mentioned above, the variable display 9
When the display result of 1a / 91b becomes a predetermined display result and the hit ball is guided to the specific winning area 102 and the specific winning ball detector is turned on, the right generation game state is set. Then, when the right generation game state continues, when the ball hits the starting winning opening 80 and the starting winning ball detector is turned on, the ball receiving members 104a and 104b perform the opening operation described above. Then, such an opening operation is repeated every time a ball hits the starting winning opening 80 as long as the right generation game state continues. However, the continuation of the right generation game state, the variable display 91a · 91 again during the right generation game state
The display result of b becomes a predetermined display result, the hitting ball is guided to the specific winning area 102, and the specific winning ball detector is turned on.
When the game is performed, or when a predetermined number (for example, 16) of ball hits in the starting winning opening 80, the game is finished.

For the winning in the starting winning opening 80, up to "predetermined number-1" winning balls are stored, and the ball receiving members 104a and 104b are opened based on the stored value. When the right generation state disappears,
After the opening operation at the time when the predetermined number is reached (even if the opening / closing operation is 16 times or less), the subsequent opening operation is not performed. Therefore, it is desirable that the winning of the ball hitting the starting winning opening 80 and the opening operation of the ball receiving members 104a and 104b are alternately performed. However, in the present embodiment, as described above, the rotation cycle of the rotating body 81. As a result, the winning in the starting winning opening 80 is made only at intervals substantially equal to the opening time of the ball receiving members 104a and 104b. Therefore, the winning in the starting winning opening 80 and the ball receiving member 104 are made.
There is a high possibility that the opening operation of a · 104b is alternately performed. Further, in the present embodiment, when the right winning game state is entered, the opening time of the ball receiving member 75 of the variable winning ball device 74 is shortened, so that the winning in the specific winning area 102 is unlikely to occur again. ing.

On the other hand, the winning port 78 arranged on the right side of the special variable winning ball device 90 is a simple winning port itself, but an operation number display LED 79 is provided so as to face the front surface thereof. In the present embodiment, the number-of-operations display LED 79 displays the plurality of times of display by the countdown method because the right generation game state may occur a plurality of times (three times) continuously at short intervals. It is a thing. In addition, the winning openings 83a, 83b provided on the diagonally lower left and right sides of the special variable winning ball device 90 are sleeve winning openings 83a.
・ It is called 83b and has a sleeve lamp inside. Further, the winning openings 87a to 87c laterally arranged below the game area 73 constitute normal winning openings 87a to 87c for simply hitting a ball. However, the number of prize balls paid out based on the winning of the hit balls to the left and right winning openings 87b and 87c is the number of prize balls paid out based on the winning of the other winning openings (for example, 15
The number is set to be less than (for example, 7).

The winning opening 84 arranged on the right side of the above-described winning opening 83a is called a passage opening device 84, and a passage switch 85 is built in a hollow square passage frame protruding from the mounting substrate. There is. Then, when the hitting ball passes through the passing frame and the passing switch 85 is turned on, the fluctuation of the variable indicators 91a and 91b is started, and when a certain time (for example, 5.5 seconds or more) elapses. , The display result is derived. In addition, although the passage opening device 84 is for releasing the passed hit balls to the game area 73 again, it may be formed as a winning opening. In addition, the passage device 8
As described above, 4 changes the variable indicators 91a and 91b to indirectly open the ball receiving member 75 of the variable winning ball device 74. Therefore, the hitting ball is a specific winning of the special variable winning ball device 90. It is largely related to whether or not it is guided to the area 102. Then, the movable member 86 which is projected and retracted by the operation of the solenoid is provided from the rear surface of the mounting board on the upper part of the passage frame, and in the normal state, the movable member 86 is retracted to the rear of the mounting board to continue the right generation game state In, the movable member 86 is projected to the front of the mounting substrate. By configuring the passage opening device 84 in this manner, it is possible to configure a right generation game state extinction prevention control means. However, both the right generation game state extinction control means by the control of the ball receiving member 75 and the right generation game state extinction control means by this passage opening device 84 may be adopted at the same time, but either one is adopted. It is enough.

Next, the structure of the special variable winning ball device 90 arranged in the center of the game area 73 is shown in FIGS. 28 and 29.
Will be described with reference to. The special variable winning ball device 90 has a mounting substrate mounted on the surface of the game board 71, and the variable display devices 91a, 91b and the ball receiving members 104a, 104b constituting the variable winning ball device are integrated on the mounting substrate. Has been formed. The variable indicators 91a and 91b are composed of dot matrix LEDs, and the variable indicator 9 on the left side is used.
1a sequentially displays 10 types of numbers 0-9, and the variable display 91b on the right side sequentially displays 11 types of numbers 0-9 and the letter F. There is. Then, when the combination of the symbols at the time of stop (display result) is the combination of "Zeros with the same number", it is determined that the specific display result is displayed, and the ball receiving member 75 is held for a certain time as described above. Open. In addition, the probability that the specific display result is displayed is controlled to change. Specifically, in the normal game state, 1/33
The specific display result is derived with a low probability of 0, and the occurrence of the right occurrence game state is "3.3" or "5.5" of the specific display results.
And 1/3 when generated by the doublet of "7.7"
It is changed to a high probability of 3, and is changed to a low probability when the right occurrence game state is established a predetermined number of times (for example, 2 times) after the high probability. Therefore, "3.3" and "5.5"
And the doublet of "7.7" will constitute a probability variation pattern. It should be noted that the determination of whether or not it is a win, and the determination of the symbol displayed on the variable display units 91a and 91b at the time of stop is one value out of a random number predetermined when the passage switch 85 is actuated or when the fluctuation starts Is extracted.

A winning space is formed below the variable display devices 91a and 91b. In the winning space, the winning balls received by the ball receiving member 75 of the variable winning ball device 74 are guided and rotated by the motor 97 to rotate normally 97 or the specific winning area 10
It can be divided into two. Then
The structure in the winning space will be described with reference to FIG. 23. The winning balls received by the ball receiving member 75 flow down through a ball passage 92 formed in a U shape, and the central portion of the ball rolling plate 95. Is guided to the rotating body 97 from the ball outlet 93. The ball rolling plate 95 is formed in the winning space so as to incline downward from the front and rear toward the normal winning region 96 formed in the front. By the way, ball passage 92
Is for guiding the winning prize balls that are flowing down in a line, and when the first winning prize ball P1 reaches the rotating body 97 and is stopped, the fourth winning prize ball from the first winning prize ball P1. P
The ball outlets 94a and 94b (9
4a is formed (not shown), and is guided to the normal winning area 96 through both sides of the ball rolling plate 95 as shown by the arrow in FIG. Therefore, three winning balls P1 to P3 are stored in the ball passage 92 on standby, and further winning balls are guided to the normal winning area 96 without being stored.

The rotating body 97 faces the ball outlet 93 formed at the lower end of the ball passage 92. The rotating body 97 is surrounded by an enclosure frame 98 and rotates in the horizontal direction, and the outer periphery of the rotating body 97 receives one winning ball.
-A plurality (three) of 99b and 100 are formed. Of the receiving recesses, the two receiving recesses 99a and 99b penetrate vertically, and one receiving recess 100 has a bottom plate. Therefore, the receiving recesses 99a and 99
The prize balls received in b are rotated by the rotating body 9 during the process of moving.
Normal winning opening 101 formed in the bottom plate on which 7 is placed
It is dropped from and is guided to the normal winning area 96. on the other hand,
The winning balls received in the receiving recess 100 are guided to the specific winning area 102 formed in the front center of the ball rolling plate 95 without dropping from the normal winning opening 101.

The rotating body 97 is rotationally driven by a motor (not shown) as described above, but the motor is constantly rotating at a constant speed (for example, 10 rpm) and the ball receiving member 75 is opened. It is temporarily stopped at a predetermined position for a period before and after, and then continues to rotate. In this case, when three winning balls are stored in the ball passage 92, any one winning ball of the three winning balls is surely received in the receiving recess 100 and guided to the specific winning area 102. The right generation game state is caused by being burned.
A stop position detector (not shown) is provided to stop the rotating body 97 at a predetermined position.

The structure of the winning space is as described above,
Below the mounting board below the winning space, the winning area 103
Is formed, and a pair of ball receiving members 104a and 104b are provided so as to be openable and closable in order to control the winning of a ball hitting the winning area 103. In this embodiment, the ball receiving members 104a and 104b constituting the variable winning ball device are provided integrally with the special variable winning ball device 90, but this is configured as a separate body on the game board 71. You may arrange. Similarly, the variable display devices 91a and 91b may be configured and arranged separately from the special variable winning ball device 90.

Even in the pachinko gaming machine having the above-mentioned game contents, the probability improving period is extended as long as the display result of the variable display devices 91a and 91b displays the probability variation pattern, so that the right generation game state is set at a short time interval. Since it occurs continuously, it causes a great deal of damage to the game arcade, but in order to prevent such a disadvantage, the variable display 91a.
In the control of 91b, FIG. 21, FIG. 23, and FIG.
By performing the same process as in 4, it is possible to prevent the right-occurring game state from continuously occurring at short time intervals and prevent a great damage to the game hall. Also, FIG.
The upper limit number N of the probability variation in each processing of FIG. 1, FIG. 23, and FIG. By making it possible, it becomes possible to provide a ball game machine that can meet the needs of the hall side. Furthermore, by increasing the probability variation upper limit value number N according to a predetermined game state by the predetermined value variation control means of FIG. 25 or FIG. It is possible to improve.

In the above embodiment, the variable display 91a.
Even if 91b displays the specific display result, the specific winning area 102
I explained an example in which the right generation game state is not entered unless a hit ball is won (such a variable display device is called a normal symbol variable display device), but when the display result of the variable display device shows a specific display result The variable display device (this is called a special symbol variable display device) that is always in the right generation game state may be provided. An embodiment provided with such a special symbol variable display device is shown in FIG.

The special variable winning ball device 110 arranged in the center of the game board has a ball entrance 111 at the uppermost part thereof, and a ball hit from the ball entrance 111 is a symbol switch 112 provided below. It is guided to and stopped. Design switch 1
When 12 is turned on by a winning ball, the variable display device 113 having three variable displays starts to change and is stopped after a predetermined time. Then, when the display result displayed at the time of the stop becomes a predetermined specific display result (for example, doublet of the same number), the rotating body 114 starts rotating in the clockwise direction and is formed on the rotating body 114. Receiving recess 115
The prize winning ball that has been stopped at the symbol switch 112 is received, and it is led to the special winning area 116, and the special winning ball detector (not shown) is turned on to enter the right generation game state. On the other hand, when the display result of the variable display device 113 becomes a display result other than the specific display result, the rotating body 114 rotates counterclockwise to guide the winning balls received in the receiving recess 115 to the normal winning area 117, Will be processed as a prize ball. In the right generation game state, every time a ball hits the starting winning opening 120 and the starting winning ball detector 121 is turned on, the ball receiving members 118a and 118b are opened for a predetermined period and the winning area 11 is formed.
The operation of leading the ball to 9 is repeated. In this way, in this embodiment, when the variable display device 113 displays the specific display result, it is always in the right generation game state.

By the way, the manner in which the symbols displayed when the variable display device 113 according to the above-described embodiment is stopped is the specific display result is the same number, so there are 10 ways 0-9. Among them, "3,3,3", "5,5,"
In the case of the right generation game state in the special display result (probably strange pattern) of "5" and "7,7,7", the variable display device 11
3 is controlled so that the probability of displaying the specific display result is improved. Therefore, as long as the display result of the variable display device 113 displays a probability variation pattern, the probability improving period is extended, and the right generation game state continuously occurs at short time intervals, which causes a great damage to the game hall. However, in order to prevent such a disadvantage, the variable display device 113
In the control of the above, if the same processing as that shown in FIG. 21, FIG. 23, and FIG. 24 is performed, the continuous occurrence of the right generation game state at a short time interval is prevented, and the game hall is not greatly damaged. You can In addition, FIG.
3, the probability change upper limit number N in each processing can be selected and set in advance to any one of a plurality of levels by the mode setting value storage means (predetermined value setting means) as in the above-described embodiment. By doing so, it becomes possible to provide a ball game machine that can meet the needs of the hall side. Furthermore, by increasing the probability variation upper limit value number N according to a predetermined game state by the predetermined value variation control means of FIG. 25 or FIG. It is possible to improve.

In each of the above-described embodiments, a predetermined symbol is set as the special jackpot symbol. However, when the normal jackpot symbols are aligned on the specially determined hit line, the normal jackpot symbols are plural. If the special big hit symbols are lined up on a specially determined hit line, and if the special big hit symbols are lined up on the special winning line, the display result of the variable display means (variable display or pseudo-video game) that fluctuates after the big hit is displayed in advance. When the result is obtained, etc. may be used as the special display result. Furthermore, in each of the above-described embodiments, the normal symbol and the special symbol are shown to be changed in probability at the same time by the establishment of the same condition, but they may be changed in different conditions, or only one of them may be changed in probability. .

Further, in the above-mentioned embodiment, the electric variable display device provided with the LCD display 38 as the variable display device is shown, but a mechanical variable display device (for example, a drum type, a belt type or a rotating disk) is used. Type) or other electrically variable display device (eg, CRT, dot matrix LED, etc.)
May be Although the pachinko game machine is shown as the ball game machine, it may be a so-called arrangement-type pachinko game machine. Further, the entire gaming machine is configured with a display device such as an LCD display, that is, a gaming machine is configured by displaying the constituent members such as "hit balls" and "variable winning ball device" on the display in a pseudo manner. It is also possible. In this case, the payout of prize balls may be performed on behalf of points. Further, in the above-described embodiment, the electric start winning port 6 corresponding to the normal symbol variable display device has a function related to the occurrence of the specific game state, but the variable winning ball device corresponding to the normal symbol variable display device. By performing almost the same control as the present embodiment when it is assumed that it is not related to the occurrence of the specific game state, while the high probability is continued, the variable winning ball device is frequently opened, More payouts can be obtained, and the game contents can attract the player's interest in a sense different from that of the present embodiment.

[0083]
