Abstract

PURPOSE:To provide a pachinko machine without extending a probability increasing period for a big hit extending over a long period and without causing great damage on a game shop. CONSTITUTION:When a specific big hit pattern which causes the increment of probability in the probability increasing period in which high probability is prepared for the probability that becomes the big hit of rotary drums 38a-38c is displayed, a value which regulates the probability increasing period is controlled so as to be always updated to an initial value, and also, when the aggregate of the number of times of increment arrives at a prescribed value, update over that prescribed value can be suppressed. Therefore, the great damage on the game shop can be evaded without extending the probability increasing period extending over the long period.

Description

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. However, the period in which the probability is improved is until the specific game state occurs a predetermined number of times (for example, twice or three times).

However, in the above-mentioned ball game machine, even if the display result during the probability improvement period becomes the special big hit display result again, it is processed as a simple big hit display result and is one of a predetermined number of times. Since it is counted, there is a problem that the probability improvement period is not extended and the player feels lost. In order to solve such a problem, the present applicant has previously proposed that in Japanese Patent Application No. 4-351708 (hereinafter referred to as the prior art), the display result of the variable display device during the probability improvement period is the cause of the probability improvement. We proposed a ball game machine that can give a player a sense of satisfaction by extending the probability improvement period when a certain special display result is obtained.

[0004]

However, in the above-mentioned prior art, 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, and it is very difficult for a game arcade to play. The disadvantage is that it causes a lot of damage. The present invention has been made in view of the above circumstances,
It is an object of the present invention to provide a ball-playing machine that does not cause a great damage to the game arcade without the probability improvement period being extended over a long period of time.

[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,
And a suppression unit that suppresses the control related to the probability improvement according to the determination result of the determination unit.

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.

[0007]

When the predetermined condition is satisfied during the probability improving period improved by the probability improving unit, the probability improving number updating unit operates to update the value of the predetermined number of times for restricting the probability improving period. When the cumulative total of the number of times of reaching a predetermined value reaches a predetermined value, the control regarding the probability improvement is suppressed. As an aspect of updating, the initial setting value may be newly updated, or the initial setting value may be added to the remaining number of times, or further, each predetermined value may be added. As the suppressing means, the operation of the probability improving means may be immediately prohibited, the satisfaction of the predetermined condition may be prohibited, or the probability of the predetermined condition being satisfied may be suppressed. As described above, in the present invention, when the predetermined condition that causes the probability improvement is satisfied during the probability improvement period, the value that regulates the probability improvement period is updated, and as a result, the probability improvement period is extended. Therefore, while it is possible to give the player a sense of satisfaction, when the cumulative number of improved times reaches a predetermined value, further updating is suppressed, so that the probability improving period is extended over a long period of time. It will not be extended and will not cause significant damage to the playground.

An example of the specific operation of the game control circuit described above will be described with reference to the time charts and explanatory diagrams shown in FIGS. First, the operation of the variable display 35 for normal symbols will be described with reference to FIGS. FIG. 5 is a time chart showing the operation of the variable display 35 for ordinary symbols based on the passage of the ball hitting the passage openings 21a and 21b, and FIG. It is explanatory drawing explaining the selection method of the determined winning symbol. In the figure, a hitting ball passes through the passing ports 21a and 21b and turns on passing ball detectors 22a and 22b,
When the passing signal T1 is derived, one value is extracted from the random 4 when the passing signal T1 rises. Random 4 is a random number for determining whether or not it is a winning symbol, as shown in FIG. 6, and as shown in FIG. 16 described later, 15 different numerical values of “0 to 14” are set for each interrupt process. It is changing every moment. Further, after the passage signal T1 is derived, 0.
The value of random 4 stored when 002 seconds has elapsed is read out, and one value is extracted from random 5 when the read value of random 4 does not hit. This random 5
As shown in FIG. 16, 0 and 1 change every interruption processing and every interruption processing remainder time,
When 0 is extracted, "3" is displayed on the variable display 35 for normal symbols at the time of stop, 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. The above-mentioned hit / miss determination is at a normal probability time (hereinafter, referred to as a low probability time),
As will be described later, when the probability is changed (hereinafter referred to as high probability), when the value extracted from Random 4 is any value of “1 to 10”, it is determined to be a hit. It is supposed to be done. Therefore, the probability of winning in the low probability is 1/15, while the probability of winning in the high probability is 10/15, which is 1
It has been changed to 0 times. The multiple at high probability may be adjusted to an arbitrary value by the above-mentioned setting switch 64 or the like (a separate switch may be provided).

As described above, when the passing 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 there is a high probability, the hit is made early and the electric start winning opening 6 is opened to generate a large number of starting winning balls.
The rotations of 8a to 38c are continuously performed, and this is to attract the player's interest at a high probability.

The variable display 3 for ordinary symbols as described above
The game after 5 stops changing display is shown in FIGS. 7 and 8. FIG. 7 is a time chart showing the operation of the electric start winning opening 6 when the stop symbol is a win, and FIG.
[Fig. 6] is a time chart showing the operation of the electric start winning opening 6 when the stop symbol is disengaged. Therefore, referring to FIG. 8 first, the case of disengagement will be described. After the variable display of the normal symbol variable display 35 is stopped, a small time (0 .0
After the passage of 02 seconds), if there is a passing memory, the variable display 35 for normal symbols starts changing again.

Next, referring to FIG. 7, the case of winning will be described. After a fixed time (0.500 seconds) has passed after the variable display of the normal symbol variable display 35 is stopped, the electric starting winning opening 6 is opened until a fixed time (3.000 seconds) has passed. However, when three winning balls are accepted during the opening, the opening is stopped even before the predetermined time has passed. Then, after the opening of the electric start winning opening 6 is finished, when a minute time (0.002 seconds) has elapsed, if there is a passing memory, the variable display 35 for normal symbols starts changing again.

When a ball hits the electric start winning opening 6 opened as described above, the rotary drums 38a to 38c start rotating. The operation will be described with reference to FIGS. 9 and 10. FIG. 9 shows a starting winning opening 5 and an electric starting winning opening 6.
9 is a time chart showing variable display control of the rotary drums 38a to 38c when a hit ball is won. FIG. 10 is an explanatory view for explaining a method of selecting a big hit symbol which is determined when the hitting ball has won the starting winning opening 5 and the electric starting winning opening 6. However, FIG. 10 shows the case where the setting value is “2” when the setting switch 64 is provided. In the figure, when a ball hits the starting winning opening 5 and the electric starting winning opening 6, the starting winning ball detectors 8 and 9 are turned on, and the starting signal S1 is derived, random 1 is generated at the rising of the starting signal S1. And one value is extracted from each of random 2 and random 3. Random 1 is a random number for determining whether or not it is a big hit symbol as shown in FIG. 10, and as shown in FIG. 16 described later, 24 of “0 to 247” for each interrupt process after power-on.
Eight numerical values fluctuate moment by moment, and Random 2 is a random number for determining the arrangement pattern of the big hit symbols, and it is "0 to 23" for each interrupt process after power-on and for each extra time of the interrupt process. , 24 random numbers are fluctuating every moment, and the random number 3 is a random number for determining the display pattern of the out-of-design, and is set to "0" for each interrupt process after power-on and for each extra time of the interrupt process. ~ 5
The number of 5832 "831" is changing every moment.
In addition, when 0.130 seconds have passed after the start signal S1 was derived, the value stored in Random 1 was read,
When 32 seconds have passed, the values of Random 2 and 3 stored are read out, and one value is extracted from Random 6.
The random number 6 is a random number for determining the symbol displayed on the decorative symbol 34, and is not directly related to the game content.

Thus, 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 (see FIGS. 14 and 15 which will be described later). Is shown on the rotary drums 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, and the symbol arrangement pattern corresponding to the value of the random 3 extracted at that time is displayed on the rotary drums 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 a big hit failure is in the case of normal probability (hereinafter referred to as low probability), and as will be described later, when the probability is changed (hereinafter referred to as high probability), The value extracted from 1 is "128
When the value is any of "~ 137", it is determined to be a big hit. Therefore, the probability of a big hit at a low probability is 1/248, whereas the probability of a big hit at a high probability is 10/248, which means that the probability is changed to 10 times. The multiple at high probability may be changed and adjusted to an arbitrary value by the above-described setting switch 64 or the like (a separate switch may be provided).

As described above, when the start signal S1 is derived, it is determined whether or not the symbols displayed on the rotating drums 38a to 38c are hit, and the symbols displayed at the stop are also determined. After the end (in this embodiment, 0.156 seconds to 0.164 seconds after the start signal S1 is derived), the fluctuations of the rotating drums 38a to 38c are started with a slight time difference. Then, the left rotating drum 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 variation display of the right rotating drum 38c, the variation is set at a predetermined variation speed during 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 central rotating drum 38b, when the stop symbol on the hit line displayed on the rotating drums 38a and 38c which has already stopped is not the big hit symbol (when it is not in the reach state), it is the big hit symbol. The time (in the reach state) is variably displayed in a different mode. 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 rotary drums 38a-38 are arranged as described above.
The game after c stops changing display is shown in FIG. 11 to FIG.
Shown in. FIG. 11 shows the rotating drums 38a to 3a when the start winning memory is stored after the opening operation of the variable winning ball device 10 is completed.
It is a time chart showing the fluctuation of 8c, FIG. 12 is a time chart showing the operation of the variable winning ball device 10 when the stop symbol is a big hit, and FIG. 13 is a case where the stop symbol is out. 3 is a time chart showing the operation of the variable winning ball device 10. Therefore, referring to FIG. 13 first,
Explaining the case of disconnection, the three rotary drums 38
Among the a to 38c, the rotary drum 38 that finally stops changing
A fixed time (1.200 seconds) after the fluctuation display of b is stopped
The value stored in Random 1 is read at the time when has passed, and the values of Random 2 and 3 stored at the time when 1.202 seconds have passed are read, and one value is extracted from Random 6. Then, after 0.156 seconds or 0.164 seconds have passed, first, the left rotary drum 38a starts to change, the middle rotary drum 38b starts to change with a slight delay, and further, although not shown, the right rotary drum 38c. Also starts to fluctuate with a slight delay.

Next, referring to FIG. 12, the case of the big hit will be described. After a fixed time (5.650 seconds) has elapsed after the variable display of the three rotary drums 38a to 38c has stopped, the variable winning ball The 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, there are 24 ways in which the symbols displayed when the rotary drums 38a to 38c are stopped are combinations of the big hit symbols, as described above, when the three hit lines shown in FIG. 15 are taken into consideration. There are 24 ways of combination, and as shown in FIG. 14, they are made to correspond to random 2 of “0 to 23”. And among the jackpot combination modes, “7 (CHANSE)” and “BI
In the case of a special game state with a special big hit symbol of "G" (any hit line is acceptable), a variable display 3 for ordinary symbols
5 and the rotating drums 38a to 38c are controlled to improve the probability of displaying the specific display result. This point will be described with reference to FIGS. 16 to 19. FIG. 16 shows that an interrupt signal (periodic reset signal) is input (for example,
2 msec) is a flow chart showing a main routine, FIG. 17 is a flow chart showing a fluctuation counter update subroutine for probability fluctuation, and FIG. 18 is a flow chart showing a fluctuation regulation subroutine for probability fluctuation. FIG. 19
FIG. 19 is a timing chart showing an example of a specific operation of the processing shown in FIGS. 17 and 18.

In FIG. 16, 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 in S20, whether or not there is a RAM error ( R
(AM normal) is determined, and if normal, various information data is output from the I / O in S30, and then it is determined in S40 whether or not there is an alarm due to an abnormality in various switches, and the abnormality is detected. If not, the special symbol process process and the normal symbol process process are executed in S50. In the special symbol process process, the rotation control of the rotary drums 38a to 38c and the opening / closing control of the variable winning ball device 10 in the big hit are performed. Further, in the normal symbol process process, the variable display control of the normal symbol variable display 35 and the opening / closing control of the electric start winning opening 6 at the time of hitting are performed. Above S
After the end of the process of 50 and when it is determined that there is an abnormality in S40, the process of accepting the input signals from the various switches is performed in S60, and then in S70, the random 1, 4
Creation (update process), Random 2, 3, 5, 6 in S80
Is created. When it is determined that there is a RAM error in S20, the initialization is performed in S120, and then the processes of S70 and S80 described above are 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, a 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, in S100) is displayed. , Numerical display 16 etc.) and sound data output are executed, and when the value of the interrupt counter is “1 to 7”, the output data table selection control and the decorative LED and lamp display control are executed in S130. . After that, the random number 2, 3, 5, 6 creation process (update process) is executed in S110 until the next interrupt signal (periodic reset signal) is input.

Incidentally, 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. 17. First, in S200, it is determined whether or not a big hit. If it is not a big hit, the subroutine is terminated, 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. 19 (B), the high-probability state appears once, and as a result, at least two jackpot game 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, the probability 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 fluctuation is performed as described in the flow chart of FIG. Therefore, referring to FIG. 18, 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 "6 or more". If it is determined that the value of the probability variation regulation counter C2 is not "6 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, and then S350. Set to a high probability with and end the subroutine. On the other hand, the probability fluctuation regulation counter C2
When it is determined that the value of is greater than or equal to “6”, the value of the probability variation regulation counter C2 is reset to “0” in S360, and the value of the probability variation regulation counter C2 is reset to “0” in S360.
At 370, the value of the probability variation counter C1 is also reset to "0" and the subroutine is finished. When the value of the probability fluctuation counter C1 is set to "0" in S370, the fluctuation operation of the rotating drums 38a to 38c is executed with a low probability without being changed to a high probability in the subsequent processing, and the probability is improved. The period will not be extended.

FIG. 19C is shown as a concrete example of the above-described operation of FIG. FIG. 19C is a time chart in the case where the big hits successively occur at "7 chances" of the probability variation pattern, and when the big hits continuously occur at "7 chances" in this way. , 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, but the value of the probability fluctuation regulation counter C2 is "5", that is, the big hit is continuous. After 5 times, the value of the probability variation counter C1 is reset to "0", so that the processes of S320 to S350 are not executed and the probability immediately returns. Therefore, the big hit game state is suppressed in a short period with respect to subsequent fluctuation results of the rotating drums 38a to 38c. Therefore, it does not cause much damage to the game arcade. It should be noted that FIG. 19C shows 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" by accident. In this case, The probability variation regulation counter C2 newly starts counting.

In the above 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. 20 and 21 may be performed. FIG. 20 is a flow chart for surely preventing the appearance of the probability variation pattern, and FIG. 21 is
It is a flow diagram for suppressing the appearance of a probability variation pattern. First, referring to FIG. 20, S80 and S11 are 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 fluctuation regulation counter C2 is "6 or more". If it is "6 or more", it is determined that the cumulative count value exceeds the planned value, and the current value of the random 2 is 2 at 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 terminated 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
4)), it is possible to completely prohibit the occurrence of a 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 "6", 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. In this way, 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 softened 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. 21. 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 a part of the probability variation pattern, 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 "6 or more". If it is not "6 or more", the cumulative count value has not yet exceeded the planned value. Therefore, the subroutine is terminated without executing the following processing. If "6 or more", the cumulative count value does not exceed the planned value. Because it exceeds, S530
Then, the values of the random 2 "18, 20, 21, 23" are rewritten to "6, 8, 12, 14" which do not correspond to the probability variation symbol, and the subroutine is finished. Thus, FIG.
When the cumulative count value exceeds the planned value, the process shown in 1
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 above-mentioned embodiment, as a game content of the pachinko gaming machine having the variable display device (rotating drums 38a to 38c), when the display result of the variable display device becomes a combination of the big hit symbols, it becomes a specific game state. 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 start winning opening during the continuation of the right-generating game state, and such opening is repeated a predetermined number of times on condition that the starting winning opening receives the hit ball. It may be a pachinko gaming machine having a game content (so-called property). Such an embodiment will be briefly described with reference to FIGS. FIG. 22 is a front view of a game board provided with a game device for implementing other game contents, and FIG. 23 shows an internal structure of a special variable winning ball device provided in the center of the game board. FIG. 24 is a perspective view, and FIG. 24 is a front view of a main portion of a game board provided with a special variable winning ball device according to another structure.

In FIG. 22, the inside of the guide rail 72 provided in a substantially circular shape of the game board 71 is configured as a game area 73, and the 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 are guided to the specific winning area 102 in association with the display result of the variable display devices 91a and 91b becoming a predetermined specific displaying result, 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-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 in detail later, 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 predetermined time (for example, 9.5 seconds) elapses, or until a predetermined number (for example, 10) of winning balls are generated until the predetermined time elapses. The rotation cycle of the rotating body 81 is the same as the ball receiving member 104.
It is set almost the same as the opening time of a and 104b.

Here, the contents of the game in the right generation game state will be briefly described. As described 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. In the present embodiment, however, 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.
It is highly possible that the opening operations of a and 104b are 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. Further, the winning holes 83a, 83b provided on the diagonally lower left and right sides of the special variable winning ball device 90 are the sleeve winning holes 83.
They are referred to as a and 83b, and a sleeve lamp is built in the 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, 1
The number is set to be less than 5 (for example, 7).

The winning opening 84 arranged on the right side of the winning opening 83a is called a passage opening device 84, and a passage switch 85 is built in a hollow square passage frame projecting on the mounting substrate. There is. Then, when the hit ball passes through the passage frame and the passage switch 85 is turned on, the fluctuations of the variable indicators 91a and 91b are started, and when a predetermined 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, so that the ball is a special winning ball 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 configuration of the special variable winning ball device 90 arranged in the center of the game area 73 is shown in FIGS. 22 and 23.
Will be described with reference to. The special variable winning ball device 90 has a mounting board that is mounted on the surface of the game board 71, and the variable display devices 91a and 91b and the ball receiving members 104a and 104b constituting the variable winning ball device are integrated on the mounting board. 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 at the time of operation of the passage switch 85 or at the start of fluctuation. Is extracted. Further, the values of the high probability and the low probability described above may be changed by a setting switch. For example, low probability is 1/3
High probability in the range of 30 to 1/390 corresponding to 1 /
In the range of 33 to 1/39, a plurality of stages (for example, 3
It may be changed and set in step).

A prize 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, 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. The outer periphery of the rotating body 97 receives a winning ball.
A plurality (three) of a, 99b, and 100 are formed. Of the receiving recesses, the two receiving recesses 99a and 99b are
It penetrates in the up-down direction, and one receiving recess 100 has
A bottom plate is formed. Therefore, the receiving recesses 99a, 9
The winning balls received in 9b are the normal winning openings 10 formed in the bottom plate on which the rotating body 97 is mounted in the process of moving.
It drops from 1 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 driven to rotate by a motor (not shown) as described above. 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 the present 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 indicators 91a and 91b may be arranged and arranged separately from the special variable winning ball device 90.

Also in the pachinko gaming machine having the above-mentioned game contents, the probability improving period is extended as long as the display results of the variable displays 91a, 91b display the probability variation symbols, so that the right-occurrence gaming state at short time intervals. 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, the above-described FIG. 18, FIG. 20, and FIG.
If the same process as 1 is performed, it is possible to prevent continuous occurrence of the right-occurring game state in a short time interval and prevent a great damage to the game hall.

In the above-mentioned embodiment, the variable indicators 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 hit ball won 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 obtained.
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 mode in which the symbols displayed when the variable display device 113 according to the above-mentioned 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 (probability variation 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 above control, if the same processing as that shown in FIG. 18, FIG. 20, and FIG. 21 is performed, continuous occurrence of the right-occurrence game state at short time intervals is prevented, and a great damage is not given to the game hall. You can

Although a plurality of embodiments have been described above, in any of the embodiments, the display result of the variable display devices 38a to 38c, 91a, 91b, 113 during the probability improvement period is a certain change that causes the probability improvement. When the symbols are displayed, the value of the probability variation counter C1 that regulates the probability improving period is updated, so that the probability improving period is extended as a result, and the player can be satisfied. On the other hand, when the probability variation regulation counter C2 that counts the cumulative number of improved times reaches a predetermined value, the probability variation counter C1 is reset, or the appearance of the probability variation symbol is prohibited or suppressed, so that the probability improvement period beyond that. The extension of the game will be suppressed, and the game hall will not be greatly damaged.

In the control operation described above, the value of the probability variation counter C1 is updated and set to the initial setting value as the updating mode. However, the residual value of the probability variation counter C1 is set to the initial setting value or an arbitrary value. An addition update setting mode in which a numerical value (for example, 1) is added may be used. In addition, the value of the probability fluctuation counter C1 and the value of the probability fluctuation regulation counter C2 are displayed on a dedicated display device or other display device (for example, a numerical display device 16, a decorative design 34, or a variable display for ordinary designs). The display may also be displayed on the device 35). In the case of dual-purpose display, the displayed area is divided and the original display information and C1,
The value of C2 may be displayed simultaneously, or may be displayed alternately every predetermined time. Further, in the above-mentioned embodiment, as the establishment of the predetermined condition, among the combinations of big hit symbols, when the combination of probability variation symbols is established, for example, a random number exclusively for probability variation extracted when a big hit occurs in advance. When it reaches the specified value, or for a predetermined period (for example,
Every time a predetermined time has passed from the start of business, when there was a predetermined number of starts after the big hit, when there was a predetermined number of reach after the big hit) It may be when the phenomenon is established. Further, in the above-mentioned embodiment, a predetermined symbol is set as the special jackpot symbol, but when the normal jackpot symbol is aligned on the specially determined hit line, the normal jackpot symbol is arranged on a plurality of hit lines. When they are aligned at the same time, when the special jackpot patterns are aligned on a specially defined hit line, and when the variable display means (variable display device or pseudo video game) that fluctuates after the jackpot is displayed, the display result is a predetermined display result. In this case, etc. may be used as the special display result. Further, in the above-mentioned embodiment, 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 different conditions may be used, or only one of them may be changed in probability.

Further, in the above-described embodiment, the mechanical variable display device provided with the rotating drums 38a to 38c is shown as the variable display device, but an electrical variable display device (for example,
It may be an LCD, CRT, dot matrix LED) or other mechanical variable display device (for example, belt type or rotating disk type). Although the pachinko game machine is shown as the ball game machine, it may be a so-called arrangement-type pachinko game machine. 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.

[0061]

As is apparent from the above description, in the present invention, when the predetermined condition that causes the probability improvement is satisfied during the probability improvement period, the value for restricting the probability improvement period is updated. Therefore, as a result, the probability improvement period is extended, and it is possible to give the player a sense of satisfaction.On the other hand, when the cumulative number of improved times reaches a predetermined value, further updates are suppressed. Therefore, the probability improvement period is not extended over a long period of time, and the game hall is not damaged significantly.
