DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine or a coin game machine, and more particularly to a game machine including a variable display device whose display state can be changed, wherein a display result on the variable display device is predetermined. The present invention relates to a gaming machine in which a predetermined game value can be given when the display mode is changed to the display mode.

[0002]

2. Description of the Related Art As a gaming machine, a variable display device having a variable display portion whose display state can be changed is provided, and when a display result of the variable display portion becomes a predetermined specific display mode, a predetermined game is performed. Some are configured to provide value to the player. Some variable display devices have a plurality of variable display units, and are generally configured to display the display results of the plurality of variable display units at different times. On the variable display section, for example, a plurality of identification information such as symbols are variably displayed. The fact that the display result of the variable display unit is a combination of predetermined specific display modes is usually referred to as “big hit”. In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0003] In addition, among the combinations of the display modes of "outside" other than the combination of "big hit", at a stage where some of the display results of the plurality of variable display portions have not been derived and displayed yet, the display results are already displayed. The state in which the display mode of the variable display unit that is derived and displayed satisfies the display condition that is a combination of the specific display modes is referred to as “reach”. A player plays a game while enjoying how to generate a big hit.

In such a gaming machine, for example, a count value as a random value is set to 1 in response to a pulse signal generated every 2 ms.
The count value is extracted at the time of the start winning, which is a condition for starting the variable display on the variable display unit, and the extracted count value is compared with the winning determination value to determine whether or not to make a “big hit”. Here, the count value counted up every 2 ms is of a cyclic type that returns to 0 when it reaches a predetermined value, and thus the count value has a certain periodicity. Therefore, if the cycle of the count value is found by any method, the timing at which the "big hit" occurs and then the next big hit occurs will be easily recognized. When the timing is recognized, it becomes possible to fire a game ball for starting and winning from the point in time when the timing is approaching, and the occurrence frequency of “big hit” for the game ball spent in the game increases. Could be That is, the fairness of the game may not be maintained. Furthermore, if the timing of occurrence of a big hit is recognized by illegal means, a so-called aiming shot is taken in accordance with the timing, and a large amount of prize balls are paid out, causing a great damage to the game store.

[0005]

As described above, in the conventional gaming machine, although the random number value for determining whether or not to generate a "big hit" has a periodicity, it is legal, but for a game store. There is a problem that a game is played by a game method that causes damage, or an illegal game is easily played by an illegal means.

Accordingly, an object of the present invention is to provide a gaming machine which can make it difficult to recognize the timing of occurrence of a big hit and can maintain the fairness of the game.

[0007]

A gaming machine according to the present invention comprises:
A gaming machine that includes a variable display device whose display state can be changed, and that can provide a predetermined game value when a display result of identification information displayed on the variable display device becomes a predetermined specific display mode. A determination random number updating unit that updates a determination random number for determining whether or not to generate a specific display mode, wherein the determination random number updating unit includes a start-up condition that is a condition for starting variable display of the variable display device. When the stored number of winnings reaches the upper limit, updating of the random number for determination is stopped. Further, the determination random number updating means may be configured to stop updating the determination random number when the game is stopped or when there is a possibility that the game is stopped. Then, the determination random number updating means may be configured to restart the update based on another predetermined condition, even if the condition for stopping the update of the determination random number is satisfied. The other predetermined condition is created by, for example, a timer. The determination random number updating means may be configured to change the update timing of the determination random number when a predetermined condition is satisfied. The time when the predetermined condition is satisfied is, for example, when the game is started or when the game is restarted.

Specifically, a predetermined clock signal is output to the sequence control circuit unit 104. Further, the sequence control circuit unit 104 controls switching of the sequence operation between the ball hitting operation period and the recovery / ball replenishment operation period, and generates a driving pattern signal and a driving voltage switching signal necessary for driving the driving motor 94. In this embodiment, for example, a firing permission signal from the touch sensor circuit 103 or a firing control signal output from the sequence control circuit unit 104 is also supplied to the basic circuit 53.

Next, the operation will be described. FIG. 6 is a flowchart showing the operation of the basic circuit 53 on the main board 31. As described above, this process is started, for example, every 2 ms by the reset pulse generated by the periodic reset circuit 66. When the basic circuit 53 is activated,
First, the basic circuit 53 performs a stack setting process for setting a designated address of a stack pointer (step S1). Next, initialization processing is performed (step S
2). In the initialization processing, the basic circuit 53 determines whether or not the RAM 55 contains an error. If the error is included, the basic circuit 53 performs processing such as initializing the RAM 55.
Then, after performing a process of setting the command code sent to the display control board 80 in a predetermined area of the RAM 55 (Step S3), a process of outputting the command code is performed (Step S4).

Next, a process for transmitting a predetermined command for sound generation and LED lighting control to the sub basic circuit 71 of the illuminated board 35 via the illuminated board command output circuit 62 is performed. A process for transmitting data such as big hit information, start information, probability variation information, etc. to the hall management computer via the H.64 (data output process: step S5). In addition, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S6).

Next, a process of updating each counter indicating each random number for determination is performed (step S7). Hereinafter, updating the counter is referred to as counting up or adding random numbers. FIG. 9 is an explanatory diagram illustrating an example of each random number. Each random number is used as follows. (1) Random 1: Determines whether or not to generate a big hit (for big hit determination) (2) Random 2-1 to 2-3: For left and right middle out-of-design symbol determination (3) Random 3: Design of big hit Determining a combination (for determining a big hit symbol = for determining a specific symbol) (4) Random 4: determining whether or not to reach at the time of a loss (for determining a reach) (5) Random 5: determining a reach type (determining a reach operation) For the purpose of enhancing the gaming effect, random numbers other than the random numbers (1) to (5) are also used.

In step S7, the basic circuit 53
The random number for big hit determination of (1) and the random number for specific symbol determination of (3) are counted up (addition of 1). That is,
These are the random numbers for determination.

Next, the basic circuit 53 performs a special symbol process (step S8). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S9). In normal symbol processing, 7 segment LE
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display device 10 by D in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state. Further, the basic circuit 53 includes a gate sensor 12, a starting port sensor 17, and a count sensor 23 via a switch circuit 58.
Then, the state of the V count sensor 22 is input, and it is determined whether or not each winning opening and the winning device have been won (step S10).

The basic circuit 53 further performs processing for updating the display random number (step S11). That is,
The random number for determining a lost symbol in (2), the random number for reach determination in (4), and the random number for reach operation in (5) are counted up (addition of 1). However, random 2-2 is
The count is incremented when the carry of the random 2-1 occurs, that is, when the value of the random 2-1 becomes "15" and is returned to "0". Also, random 2-3
Is incremented when a carry of random 2-2 occurs, that is, when the value of random 2-2 becomes "15" and is returned to "0".

The basic circuit 53 performs signal processing with the award ball substrate 37 (step S12). That is, it is determined whether or not a winning data signal is output from the prize ball substrate 37, and when a predetermined condition is satisfied, the prize ball substrate 3
7 to output a prize ball number signal. The payout control microcomputer mounted on the prize ball board 37 drives the ball payout device 97 according to the prize ball number signal.

Thereafter, the basic circuit 53 repeats the display random number updating process in step S13 until a reset pulse is given from the periodic reset circuit 66 next time. That is, 1 is added to the value of each random number. Note that what is added here is, as shown in FIG.
Of the random numbers of (5), random numbers for determining the outlier symbols of (2),
These are random numbers for reach determination in (4) and random numbers for reach operation determination in (5). Again, random 2-2 is
The random 2-1 is counted up when a carry occurs, and the random 2-3 is counted up when a random 2-2 carry occurs.

Next, a method of determining a symbol variably displayed on the image display section 9 based on a winning in the starting winning opening 14 (starting winning) will be described with reference to flowcharts of FIGS. 7, 8, and 10. . FIG. 7 shows a process for determining that the hit ball has won the start winning opening 14, FIG. 8 shows a process for determining a stop symbol of the variable display of the image display device 9, and FIG.
Indicates a big hit determination process.

When the hit ball wins the starting winning port 14 provided in the game board 6, the starting port sensor 17 is turned on. In the switch processing of step S10, the basic circuit 53
Determines that the starting port sensor 17 has been turned on via the switch circuit 58, as shown in FIG. 7 (step S4).
1). If it is detected that the switch has been turned on, it is checked whether or not the number of memorized start winnings has reached the maximum value of 4 (step S42). If the start winning prize storage number has not reached 4, the starting prize storage number is increased by 1 (step S43), and the value of the random number for jackpot determination is extracted (step S44). If the number of stored start winnings has reached 4, the process of increasing the number of stored start winnings is not performed. In other words, in this embodiment, the number of hit balls that have won a maximum of four starting winning openings 17 is stored.

The basic circuit 53 performs the processing shown in the flow chart of FIG. 8 when the variable display of the image display section 9 can be started. First, the value of the number of memorized start winnings is confirmed (step S50). If the start winning prize memory number is not 0, the value stored in the random number storage area corresponding to the start prize storing number = 1 is read out (step S51), the value of the starting prize storing number is reduced by 1, and The value of the random number value storage area is shifted (step S52). In other words, the value stored in the random number value storage area corresponding to the number of start winning memory = n (n = 2, 3, 4) is calculated as follows:
1 is stored in the random number value storage area corresponding to 1.

Then, the jackpot determining means of the basic circuit 53 determines the hit / miss based on the value read in step S51, that is, the value of the extracted random number for jackpot determination (step S53). Here, the big hit determination random number takes a value in the range of 0 to 256.
As shown in FIG. 10, when the probability is low, for example, when the value is “3”, “big hit” is determined, and when the value is any other value, “missing” is determined. When the probability is high, for example, the values are “3”, “7”, “79”, “103”,
If it is any of "107", it is determined as "big hit", and if it is any other value, it is determined as "out".

When it is determined that a big hit has occurred, the basic circuit 5
3 determines the stop symbol based on the value of the big hit symbol determination random number (random 3). Here, if the limiter is not operating, a stop symbol is determined from a table including all symbols (steps S54 and S55). If the limiter is operating, a stop symbol is determined from a table that does not include a special symbol for which probability variation is performed (step S54,
S56). The limiter is for restricting the occurrence of the jackpot due to the probable symbol continuously, that is, the continuation of the continuous high probability state. For example, if the high probability state continues four times in a row, the limiter is activated. Therefore, in the limiter operating state, the stop symbol is determined from the table that does not include the special symbol in which the probability change is performed. Further, the basic circuit determines the reach type according to the value of the random number 5 (step S57).

Next, the basic circuit determines whether to make a big hit,
The symbol and the reach type in the case of the big hit are set in a predetermined storage area (step S58). The storage area is provided in the RAM 55 of the basic circuit 53.

If it is determined in step S53 that there is a deviation, the basic circuit 53 determines whether or not to reach (step S59). For example, when the value of the reach determination random number is any of “0” to “104”, it is determined to reach. When it is decided to reach, the basic circuit decides a stop symbol. In this embodiment, the left and right symbols are determined according to the value of the random 2-1 (step S60). In addition, the middle symbol is determined according to the value of the random 2-2 (step S61). Here, if the determined middle symbol matches the left and right symbols,
The symbol corresponding to the value obtained by adding 1 to the value of the random number corresponding to the medium symbol is set as the fixed symbol of the medium symbol so as not to match the big hit symbol.

Further, the basic circuit determines the reach type according to the value of the random number 5 (step S62). Then, “reach”, reach symbol, and reach type are set in a predetermined storage area (step S63). If the lottery result in step S59 is out of place, it is set that it is out of place in the predetermined storage area (step S64).

As described above, it is determined whether or not to make a big hit. In this example, the value of random 1 for determining whether or not to make a big hit takes a value of 0 to 249. The value of random 1 is updated in step S7 shown in FIG. 6, but step S7 is executed every 2 ms. Thus, without any consideration, the value of random 1 is
It becomes the same value in a 500 ms cycle. Therefore, as described above, if the 500 ms period is recognized by some method, a big hit is likely to be targeted.

Therefore, in this embodiment, when the predetermined condition is satisfied, the updating of the judgment random number, that is, the random 1 for the big hit determination and the random 3 for the big hit symbol judgment is stopped. In this embodiment, random 1 and random 3 updates are stopped, but only random 1 updates may be stopped.

FIG. 11 shows an example in which the number of stored winning prizes is used as the predetermined condition. That is, in step S7 shown in FIG. 6, when the number of start winning combinations becomes full (four in this embodiment) (step S111), the updating of random numbers 1 and 3 is stopped. If the start winning prize memory number is not full, random 1 and 3 are updated (step S11).
2). As described above, if the update of the determination random number is temporarily stopped, the cycle of the random number becomes difficult to recognize, and it is possible to prevent a big hit from being shot. In addition, when the start winning prize memory number is full, even if there is a starting prize, random number extraction for determining a big hit is not performed. Therefore, even if the random number update for the big hit determination is not performed, the influence on the game progress is small.

FIG. 12 shows an example in which the state of the touch sensor 93 is used as a predetermined condition. That is, in step S7 shown in FIG. 6, when the touch sensor 93 is off (step S121), the updating of the random numbers 1 and 3 is stopped. If the touch sensor 93 is on,
The random 1 and 3 are updated (step S122). When the touch sensor 93 is off, the player operates the operation knob 5
No game is played because the player does not touch the. Therefore,
Even if the random number update for the jackpot determination is not performed, there is no effect on the game progress.

It should be noted that if the processing shown in FIG. 12 is always executed, the random 1 and 3 are not always updated when the player does not touch the operation knob 5. Otherwise, when the power of the gaming machine is turned on, the processing shown in FIG. 12 is executed,
Once the touch sensor 93 is turned on, the determination random number may be updated thereafter without stopping the update. Generally, the power of each of the gaming machines installed in the game arcade is simultaneously turned on. Therefore, if no consideration is given, the value of the random number for determination in each gaming machine is substantially the same at the same timing. Therefore, when the timing at which the value of random 1 becomes the big hit determination value is found in a certain gaming machine, the timing can be applied to other gaming machines. However, if the touch sensor 93 is turned on after the power is turned on and the game is started and the update process of the judgment random number is started, the game start timing is different in each of the gaming machines. The random number update start timing is shifted, and the values of the random numbers for determination can be made different values at the same timing. Therefore, even if a timing at which the value of random 1 becomes the big hit determination value is found in a certain gaming machine, the timing cannot be applied to other gaming machines.

FIG. 13 shows an example in which the state of the firing control signal in the firing control board 91 is used as the predetermined condition. That is, in step S7 shown in FIG. 6, when the firing control signal is in the OFF state (step S131), the updating of random numbers 1 and 3 is stopped. If the firing control signal is on, random 1 and 3 are updated (step S
132). When the firing control signal output from the sequence control circuit unit 104 in the firing control board 91 is off,
No game ball has been fired from the hit ball firing device 34. That is, no game is played. Therefore, even if the random number update for the big hit determination is not performed, there is no influence on the game progress. Here, when the power is turned on, the process shown in FIG. 13 is executed, and once the firing control signal is turned on, the update random number may be constantly updated without performing the update stop process. This is the same as the case where the state of the touch sensor 93 is used. Although the firing control signal output from the sequence control circuit unit 104 is used here, the ball feeding state of the game ball supplied to the hit ball firing device 34 may be used.

FIG. 14 shows that there is a prize as a predetermined condition.
An example using none is shown. That is, in step S7 shown in FIG. 6, when there is a winning in the winning opening of a hit ball (step S141), a timer is started (step S141).
142). When the timer value is not 0, random 1 and 3 are updated (steps S143 and S14).
4). If the timer value is 0, the updating of random 1 and 3 is stopped. The timer value is subtracted by a timer control program or the like, and stops when the value becomes zero. By doing so, the timer value does not become 0 in the state where the winning is occurring, so that the determination random number is updated. Then, if no prize is generated for a predetermined period or more, the random number updating process is stopped. Since a state in which there is no winning for a predetermined period is considered to be a state in which the game is not performed, the influence on the game progress is small even if the random number update for the big hit determination is not performed. When the power is turned on, 0 is set in the timer. The winning can be detected, for example, by a winning data signal from the prize ball substrate 37. Here, when the power is turned on, the processing shown in FIG. 14 is executed, and once the timer times out,
The update of the determination random number may be always performed without performing the update stop processing, as in the case of using the state of the touch sensor 93 and the case of using the firing control signal. Further, instead of the winning, the ON of the gate sensor 12 (see FIG. 4) or the ON of the starting opening sensor 17 (winning to the starting winning opening) may be used.

Even if the number of stored start winnings is full, updating of the random number for determination may be restarted according to the situation.
FIG. 15 is a flowchart showing such an example.
If the number of start winning prize memories is full (step S151),
For example, when the opening / closing plate 20 is opened and closed during the jackpot operation, the number of occurrences of the continuation right of the jackpot operation exceeds a predetermined number (N times), or the jackpot operation starts during a symbol change that causes a jackpot. When the number of occurrences of the continuation right of the jackpot operation exceeds a predetermined number (N times) (step S1).
52), restart updating of random numbers 1 and 3 (step S)
152). In addition, during the change of the symbol which is not the big hit, the update of the random numbers 1 and 3 is restarted (Step S152) a predetermined time (n seconds) before the symbol is determined (Step S154).
In this way, the update of the determination random number is restarted before the point at which the number of start winning prize memories is not full and the random number may be extracted again by the start prize,
The effect of stopping the update of the random number for determination on the progress of the game can be further reduced.

In each of the above embodiments, the conditions for stopping the updating of the random number for determination (steps S111, S121, S131, S131)
141 and S143, S153, S154), the update is stopped continuously, but the update stop may be executed in a predetermined period. FIG.
Is a flowchart showing such an example. If the condition for stopping the update of the random number for determination is not satisfied (step S171), the random number 1 and 3 are updated (step S172). If so, the timer value is checked (step S173). If the timer value is not 0, the timer value is reduced by 1 and it is checked whether or not the state is being updated (step S175). If the update is in progress, random updates 1 and 3 are executed (step S17).
2). When the timer value becomes 0, the state is switched between the updating state and the stopped state (steps S177, S17).
8, S179), and sets a predetermined value M as the timer value (step S180). By doing so, for example, step S
111, S121, S131, S141 and S14
Even if the update stop condition as shown in S153, S153, or S154 is satisfied, the determination random number update process is executed every predetermined time M.

The determination random number update processing shown in FIGS. 11 to 16 may be executed in combination.
Further, any one or a plurality of processes may be executed in a certain period, and another one or a plurality of processes may be executed in another period. Furthermore, a part of each process executed in a certain period and a part of each process executed in another period may overlap.

In each of the above embodiments, the update of the random number for determination is performed unless the condition for stopping the update of the random number for determination is satisfied, but the update process is always performed as in the conventional case. May be set to a value other than 2 ms. FIG. 17 is a flowchart showing such an update process. That is, if the counter value is not 0, the counter value is reduced by 1 (steps S191 and S19).
2) If the counter value is 0, random 1 and 3 are updated and a predetermined value m is set as the counter value (step S193). In this way, the values of random 1 and 3 are executed every (2 × m) ms.

The control of changing the update timing of the random number for determination from every 2 ms to every (2 × m) ms may be performed at all times. However, the control may be performed only at a predetermined timing. Is also good. For example, the processing shown in FIG. 17 may be performed after the power is turned on until the game is started, and when the game is started, the update timing of the random number for determination may be returned to 2 ms. Further, the predetermined value m may be different for each gaming machine. For example, a switch is provided in the gaming machine, the switch setting is changed for each gaming machine, and the value of m is determined according to the switch setting. By doing so, even if the respective gaming machines are turned on at the same time, since the random number value when the game is started is different, the value of the random number for determination can be made different at the same timing. . The start of the game can be known by turning on the touch sensor 93 or a firing control signal.

After the update of the random number for judgment is stopped,
The update may be restarted based on the update restart timing determined in another control unit. FIG. 18 and FIG. 19 are flowcharts showing such an embodiment. The flowchart shown in FIG. 18 is different from the flowchart shown in FIG. 6 in the processing after step S13. That is, if the update restart flag is not set and the update restart count flag is not set after the display random number update process of step S13 is performed (steps S21 and S22), whether update stop is started or not is determined. Check (step S23). If the update stop is started, a predetermined value S is set in the update restart counter and an update restart count flag is set (step S24). Here, whether the update stop is started depends on the update stop condition (step S
111, S121, S131, S141 and S14
3, S153 and S154). Also,
Since the update restart flag is set when the update of the determination random number is restarted, if the flag is set, the process for determining the update restart timing (the process after step S22) is not performed.

The state where the update restart flag is not set and the update restart count flag is set is a state where the update restart counter for determining the update restart timing is operating. Therefore, the update restart counter is decremented by one (step S25). And the update restart counter is 0
Is reached (step S26), the update restart flag is set and the update restart count flag is reset (step S27).

The process of FIG. 19 is a flowchart showing an example in which this embodiment is applied to the updating process of random numbers 1 and 3 shown in FIGS. That is, the conditions for stopping the update (steps S111, S121, S131, S131)
When the update stop conditions as shown in 141, S143, S153, and S154 are satisfied (step S201), if the update restart flag is set (step S202), the random update of 1, 3 is performed. Processing is performed (step S204). Until the update restart flag is set, random 1 and 3 update processing is not performed. When the condition for stopping the update is no longer satisfied, the update restart flag is reset (step S203). According to such an embodiment, the update process of the determination random number can be restarted at a predetermined timing when the update stop condition is satisfied. Step S1 in FIG.
The time spent in the loop from 3 to S27 is relatively random. Therefore, the timing at which the value S of the update restart counter becomes 0 is also random. As a result, the timing at which the update of the random number for determination is restarted becomes random, and it becomes more difficult to recognize the cycle of the random number for determination.

As described above, according to each of the above embodiments, the periodicity of the judgment random number can be disturbed by temporarily suspending or restarting the judgment random number update process, and a big hit occurs. It becomes difficult to grasp the timing of the operation. Furthermore, since the update of the random number for determination is not stopped according to the game situation, for example, the update of the random number for determination is stopped slightly before the point at which the random number can be extracted based on a new start winning. Can be canceled, and the influence on the progress of the game can be reduced even if the control for stopping the update of the random number for determination is performed.

In each of the above embodiments, the image display unit 9 using a CRT for variably displaying a plurality of types of symbols is provided.
Has been described, but a variable display device using an LCD or a drum-type or reel-type variable display device may be used. Furthermore, the present invention can be applied to a video-type pachinko gaming machine in which the entire board surface is composed of video.

[0056]

As described above, according to the present invention, a gaming machine is identified when the random number updating means for determination has reached the upper limit of the number of stored start winnings, which is a condition for starting variable display on the variable display device. Is configured to stop updating of the random number for determination for determining whether or not to generate the display mode of the above, so that the cycle of the random number for determination can be made random, and the cycle cannot be easily recognized. There is. Also, since the random number updating means for determination is configured to stop updating the random number for determination when the game is stopped or there is a possibility that the game is stopped, the random number value is divided between the respective gaming machines. Therefore, even if the cycle of the random value of one gaming machine is recognized, the cycle cannot be applied to another gaming machine. Even if the condition for stopping the update of the judgment random number is satisfied, if the update is restarted based on another predetermined condition, the cycle of the judgment random number can be further randomized. Even when the determination random number updating means is configured to change the update timing of the determination random number when a predetermined condition is satisfied, the cycle of the determination random number can be made random, and the cycle can be easily set. Has the effect that it cannot be recognized.
