Abstract

PROBLEM TO BE SOLVED: To prevent an illegal game play by using an illegal board. SOLUTION: A value of a counter (randam 6) for determining a randam 1 initial value is extracted and stored when a value of a big prize judgement counter advances to predetermined value(s). When a value of the big prize judgement counter advances to 299, and a value is returned to 0 by adding +1 to the same, it is detected that the counter value is agreed with one round jugement value. Then a stored value is determined in the large prize judgement counter. The stored value on this occasion is 19. Accordingly the big prize jugement counter starts from an initial value 19. A timing for extracting the randam 6 to be used as a new initial value is not constant. Whereby the randomness of the initial value of the big prize jugement counter is improved, as a result, a timing for the big prize jugement counter to get the large prize jugement value becomes more at random.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko gaming machine, and more particularly, to a game played by a player's operation, and when a predetermined condition is satisfied, a specific game can be played. The present invention relates to a gaming machine capable of giving a predetermined game value to a player based on a result of a game having a predetermined mode.

[0002]

2. Description of the Related Art As a gaming machine, a game medium such as a game ball is launched into a game area by a launching device, and when a game medium wins a winning area such as a winning opening provided in the game area, a predetermined number of prize balls are obtained. Are paid out to players.
Furthermore, a variable display unit capable of changing the display state is provided,
There is a configuration in which a predetermined game value is provided to a player when a display result of the variable display unit has a predetermined specific display mode.

The variable display section has a plurality of display areas, and is usually configured to display a plurality of variable display results at different times. In the variable display unit, 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. When a "big hit" occurs, for example, a large amount of prize balls and the like are paid out to the player.

In game control of such a gaming machine, a random number is generated when a predetermined condition (for example, a start winning which is a condition for starting a variable display) is satisfied, and when a random number value matches a predetermined value determined in advance. "Big hit". In addition, the circuit portion that performs game control for noise suppression or the like is reset and restarted at a predetermined time interval (for example, 2 ms). Since the random number value is generated using a predetermined counter, and the updating of the counter value is performed in the circuit portion that performs the game control, the value of the generated random number depends on the time interval of the activation of the circuit portion that performs the game control. I have to synchronize.

[0005] Then, if the time interval of activation is detected by some means, the counter value update timing is recognized. Further, the timing at which a random number value of "big hit" occurs is recognized. Then, by aiming for the start winning at the timing when the random number value of “big hit” is generated, it is possible to frequently generate “big hit”.

[0006] In order to detect the activation timing of a circuit portion for performing game control, an illegal board may be attached to a game machine. Such a fraudulent board introduces a signal output from the circuit portion performing the game control to the outside, detects the activation timing of the circuit portion performing the game control based on the signal, and detects a random number value causing a “big hit”. The occurrence timing is detected. Then, the illegal board can send a start winning signal to a circuit portion that performs game control at that timing, thereby making it possible to illegally generate a "big hit".

For example, a display control board on which a display control microcomputer for controlling a display state of a variable display section is mounted is a display board for changing a display state from a main board on which a circuit for performing game control is mounted. A control command is sent. As described above, the circuit portion for performing the game control is reset, for example, every 2 ms, so that the transmission interval of the display control command is synchronized with 2 ms. The illegal board is connected between the main board and the display control board, and, for example, after introducing the original start winning signal and recognizing the counter value update timing based on the display control command transmission interval,
If an illegal start winning signal is sent to the main board in order to generate a random number value that causes a "big hit", the "big hit" will be illegal
Will occur.

[0008]

Since various components such as a variable display device, a decorative lamp, and a sound generating device are present in a gaming machine, a signal line from a circuit portion for performing game control to those components is eliminated. Can not. Accordingly, there is still room for the illegal board to be attached and illegal gaming to be performed. Therefore, how to prevent illegal gaming using illegal substrates has become an important issue in gaming machines.

An opening / closing plate 20 which is opened by a solenoid 21 in a specific game state (big hit state) is provided below the variable winning ball apparatus 15. In this embodiment, the opening and closing plate 20 serves as a means for opening and closing the special winning opening. The winning ball that enters one (V zone) of the winning balls guided from the opening / closing plate 20 to the back of the game board 6 is detected by the V count switch 22. The winning ball from the opening / closing plate 20 is detected by the count switch 23. Variable display device 8
A start winning prize storage display 18 having four display sections for displaying the number of winning balls entering the starting winning prize port 14 is provided below. In this example, the start winning prize storage display 18 increases the number of lit display units by one each time there is a starting prize, with the upper limit being four. Then, each time the variable display of the variable display unit 9 is started, the number of the lit display units is reduced by one.

The game board 6 is provided with a plurality of winning ports 19 and 24. Decorative lamps 25 are provided around the left and right sides of the game area 7 so as to blink during the game.
There is an out port 26 for absorbing a hit ball that does not win. In addition, two speakers 27 that emit sound effects are provided at upper left and right sides outside the game area 7. A game effect LED 28a and a game effect lamp 2

Further, when a hit ball enters the starting winning opening 14 and is detected by the starting opening switch 17, the symbol in the variable display section 9 starts rotating if the symbol can be changed. If it is not possible to start changing the symbol, the start winning memory is increased by one. The start winning memory will be described later in detail.

The rotation of the image in the variable display section 9 stops when a certain time has elapsed. If the combination of images at the time of stop is a combination of big hit symbols, the game shifts to a big hit game state. That is, the opening / closing plate 20 is opened until a predetermined time elapses or until a predetermined number (for example, 10) of hit balls is won. Then, when a hit ball wins in the specific winning area while the opening and closing plate 20 is opened and is detected by the V count switch 22, a continuation right is generated and the opening and closing plate 20 is opened again. Generation of the continuation right is permitted a predetermined number of times (for example, 15 rounds).

If the combination of images in the variable display section 9 at the time of stoppage is a combination of big hit symbols with probability fluctuation, the probability of the next big hit becomes high. That is, a high probability state, which is more advantageous for the player, is obtained. Also, when the stop symbol on the variable display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the high probability state, the probability that the stop symbol on the variable display 10 hits the symbol is increased, and the opening time and the number of times the variable winning ball device 15 is opened are increased.

FIG. 3 is a rear view of the gaming board of the pachinko gaming machine 1 as viewed from the rear. On the back of the game board 6, FIG.
As shown in the figure, the winning ball set cover 4 for guiding the winning ball winning each winning port and the winning ball device along a predetermined winning path.
0 is provided. Of the prize balls guided to the prize ball collection cover 40, those that have won through the open / close plate 20 pay out a relatively large number of prize balls (for example, 15) with a ball payout device (not shown in FIG. 3). Is controlled as follows. The winnings through the start winning opening 14 are controlled so that the ball payout device pays out a relatively small number of prize balls (for example, 6). Then, the winnings through the other winning ports 24 and the winning ball device are controlled so that the ball payout device pays out a relatively medium number of prize balls (for example, 10). Note that FIG. 3 illustrates the relay board 33 as an example.

Signals from the winning ball detection switch 99, the starting port switch 17 and the V count switch 22 are sent to the main board 31 in order to control the winning ball payout. The winning is detected by the winning ball detection switch 99,
When an ON signal of the winning ball detection switch 99 is sent to the main board 31, a winning ball control command is sent from the main board 31 to the winning ball control board 37. For example, when the winning ball detection switch 99 is turned on in response to the turning on of the starting port switch 17, a winning ball control command indicating the number of winning balls “6” is output, and the count switch 23 or the V count switch 22 is turned on. When the winning ball detection switch 99 is turned on, a winning ball control command indicating the number of winning balls “15” is output. When the winning ball detection switch 99 is turned on when these switches are not turned on, a winning ball control command indicating the number of winning balls "10" is output.

FIG. 4 is a block diagram showing an example of a circuit configuration of the main board 31. FIG. 4 also shows the prize ball control board 37, the lamp control board 35, the sound control board 70, the emission control board 91, and the display control board 80. On the main board 31, a basic circuit 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 12,

A solenoid circuit 59 for driving the solenoid 21 for opening and closing the 0 according to a command from the basic circuit 53;
It includes a lamp / LED circuit 60 for driving the variable display 10 by ED and the decorative lamp 25.

According to the data supplied from the basic circuit 53, jackpot information indicating occurrence of a jackpot, effective start information indicating the number of start winning balls used to start image display of the variable display section 9, and probability fluctuation have occurred. And an information output circuit 64 that outputs probability change information or the like indicating the fact to a host computer such as a hall management computer.

The basic circuit 53 includes a ROM 54 for storing a game control program and the like, a RAM 55 used as a work memory, a CPU 56 for performing a control operation in accordance with the control program, and an I / O port unit 57. The ROM 54 and the RAM 55 may be built in the CPU 56 in some cases.

Further, the main board 31 has an initial reset circuit 65 for resetting the basic circuit 53 when the power is turned on.
A periodic reset circuit 66 for periodically (eg, every 2 ms) giving a reset pulse to the basic circuit 53 to re-execute the game control program from the beginning, and decode an address signal given from the basic circuit 53. I
Address decode circuit 67 for outputting a signal for selecting any I / O port in I / O port unit 57
Are provided. In addition, there is also switch information input to the main board 31 from the ball dispensing device 97, but these are omitted in FIG.

A hit ball launching device that hits and fires a game ball is driven by a drive motor 94 controlled by a circuit on a launch control board 91. Then, the driving force of the driving motor 94 is adjusted according to the operation amount of the operation knob 5. That is, the circuit on the firing control board 91 is controlled so that the hit ball is fired at a speed corresponding to the operation amount of the operation knob 5.

Next, the operation will be described. FIG. 5 is a flowchart showing a main operation of the game control program executed by the CPU 56 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 CPU 56 is started, the CPU 56 firstly activates the CPU 5 to make the clock monitor control operable.
Then, the clock monitor register built in 6 is set to the clock monitor enable state (step S1). Note that the clock monitor control is a control in which a reset is automatically generated inside the CPU 56 when a decrease or stop of an input clock signal is detected.

Next, the CPU 56 performs a stack setting process for setting the designated address of the stack pointer (step S2). In this example, 00FFH is set in the stack pointer. Then, a system check process is performed (step S3). In the system check process, the CPU 56 determines whether or not the RAM 55 contains an error.
Processing such as initializing 5 is performed.

Next, after performing processing for setting a display control command sent to the display control board 80 in a predetermined area of the RAM 55 (display control data setting processing: step S
4) A process of outputting a display control command is performed (display control data transmission process: step S5).

Next, processing for outputting the contents of the storage area for various output data to each output port is performed (data output processing: step S6). In addition, output data in a storage area for various output data is set, and output data setting processing for setting output data such as jackpot information, start information, and probability fluctuation information output to the hall management computer in the storage area is performed ( Step S8). Further, various abnormality diagnosis processes are performed by a self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S9).

Next, a process for updating each counter for generating each random number for determination such as a random number for big hit determination used in game control is performed (step S10). FIG. 6 is an explanatory diagram showing 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) (6) Random 6: Determine initial value of counter for generating random 1 (for determining random 1 initial value)

Here, the random number 6 is a random number for determining a value to be newly set in the counter for generating the random 1 when the counter value for generating the random 1 goes around the predetermined number of times. Although the range of each random number shown in FIG. 6 is an example, even when a range different from the random number range shown in FIG. 6 is used, the range that random 6 can take is the same as the range that random 1 can take. Is set to

In order to enhance the game effect, random numbers other than the random numbers (1) to (6) are used. The variable display unit 9 also displays images other than the symbols, for example, a background, a character that moves in a predetermined manner, and the like, in order to enhance the gaming effect. In step S10, the CPU 56
Performs the count-up (addition of 1) of the counter for generating the big hit determination random number of (1) and the big hit symbol determination random number of (3).

Next, the CPU 56 performs a special symbol process (step S11). 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 S12). In normal symbol processing, 7 segments L
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display 10 by the ED 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 CPU 56 includes a switch circuit 58
, The state of the gate sensor 12, the starting port sensor 17, and the count sensor 23 are input, and it is determined whether or not there is a prize for each prize port or prize device (switch processing: step S13).

The CPU 56 further performs a process for updating each counter for generating a display random number (step S15). In other words, the counter that generates 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) is counted up (1).
Addition). However, random 2-2 is random 2
-1 carry, ie, random 2-
When the value of 1 becomes “15” and returns to “0”, the count is incremented. Random 2-3 is generated when a carry of random 2-2 occurs, that is, random 2
The count is incremented when the value of -2 becomes "15" and is returned to "0".

Then, a process of updating the random number for determining random 1 initial value is performed (step S16). That is, the counter for generating the random number for determining the random 1 initial value is set to +
Do one.

The CPU 56 performs a winning ball signal process with the winning ball control board 37 (step S17). That is, when a predetermined condition is satisfied, a winning ball number signal is output to the winning ball control board 37. The prize ball control CPU mounted on the prize ball control board 37 drives the ball payout device 97 according to the prize ball number signal.

Thereafter, the CPU 56 repeats the display random number updating process (the process of incrementing by one) in step S18 and the random 1 in step S19 until a reset pulse is next given from the periodic reset circuit 66, that is, in an infinite loop.
The random number updating process for initial value determination is repeated. Step S1
Since the time required for S17 is shorter than 2 ms, the display random number update processing and the random 1 initial value determination counter update processing are repeatedly executed with the remaining time until the time reaches 2 ms. If the game situation is different, steps S1-S
Since the time required for step 17 also differs, the remaining time is not a fixed time. Further, the content of the display random number update process in step S18 is the same as the process in step S15, and the content of the random 1 initial value determination random number update process in step S19 is the same as the process in step S16.

Next, a method of determining a symbol variably displayed on the variable 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 shows a process of determining that the hit ball has won the start winning opening 14, FIG. 8 shows a process of determining a symbol, and FIG. 9 shows a process of determining a big hit. The processing shown in FIGS. 7 to 9 is executed in the special symbol processing (step S11) in the main processing shown in FIG.

When the hit ball wins the starting winning port 14 provided in the game board 6, the starting port switch 17 is turned on.
The CPU 56 includes a switch circuit 58 and an I / O port 5
When it is detected that the start port switch 17 has been turned on via step 7 (step S41), it is checked whether or not the number of start winning memories has reached the start memory upper limit (step S4).
2). If the start winning storage number has not reached the start storage upper limit value, the starting winning storage number is increased by 1 (step S43).
In this embodiment, the starting memory upper limit value is 4.

Then, the value of a counter for generating a random 1 is extracted, and the extracted value is used as the number of stored winning prizes n (n
= 1, 2, 3,..., Starting memory upper limit value) (Step S)
44). In addition, when the start winning storage number has reached the start storage upper limit value, the processing of steps S43 to S44 is not performed.

When the CPU 56 is ready to start variable display on the image display section 9, it performs the processing shown in the flowchart of FIG. 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). That is, the value stored in the random number storage area corresponding to the number of start winning storage = n (n = 2, 3,...)
It is stored in the random value storage area corresponding to -1.

Then, the CPU 56 determines the hit / miss based on the value read in step S51, that is, the value of the extracted big hit determination random number (step S53). In this embodiment, the big hit determination random number takes a value in the range of 0 to 299. And FIG.
As shown in (2), when the probability is low (when the later-described probability change flag is not set), for example, if the value is “3”, “big hit” is determined, and if the value is any other value, “big hit” is determined. Mistake ". At the time of the high probability, for example, if the value is any one of “3”, “7”, “79”, “103”, and “107”, it is determined to be “big hit”. Mistake ".

When it is determined that a big hit has occurred, the CPU 56
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 (probably variable symbol) in which probability change is performed (steps S54 and 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.

Then, the reach type is determined according to the value of the random number 5 (step S74), and whether or not a big hit is determined is determined.
The symbol and the reach type in the case of the big hit are set in a predetermined storage area (step S75). 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 CPU 56 determines whether or not to reach (step S59). For example, when the value of the reach determination random number shown in FIG. 6 is any of “0” to “104”, the reach is determined. When determining to reach, the CPU 56 determines 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 middle symbol is determined as the middle symbol, so that it does not match the big hit symbol. I do.

Further, the basic circuit determines a 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).

FIG. 10 is a flowchart showing an example of a special symbol process program in the main process. The special symbol process process shown in FIG. 10 is a specific process of step S11 in the flowchart of FIG. When performing the special symbol process processing, the CPU 56 determines in step S3 shown in FIG.
One of the processes from 00 to S309 is performed. In each process, the following processes are performed.

Special symbol change waiting process (step S30)
0): The start winning port 14 (in this embodiment, the winning port of the variable winning ball device 15) is hit and the start port sensor 17 is turned on. When the starting port sensor 17 is turned on, the starting winning memory number is increased by + if the starting winning memory number is not full.
1 and a big hit determination random number is extracted. That is, the processing shown in FIG. 7 is executed. Special symbol determination processing (step S301): When a state in which the variable display of the special symbol can be started, the number of start winning prizes is confirmed. If the number of start winning prizes is not 0, it is determined whether to make a jackpot or not according to the value of the extracted jackpot determination random number. That is, the first half of the processing shown in FIG. 8 is executed. Stop symbol setting process (step S302): A stop symbol for the left and right middle symbols is determined. That is, the middle half of the processing shown in FIG. 8 is executed.

Reach operation setting processing (step S30)
3): Whether or not the reach operation is performed is determined according to the value of the reach determination random number, and the variation mode of the reach operation is determined according to the value of the reach random number. That is, the latter half of the process shown in FIG. 8 is executed.

All symbols change start processing (step S30)
4): In the variable display section 9, control is performed so that all symbols start to change. At this time, with respect to the display control board 80,
The left and right middle final stop symbols and information instructing the variation mode are transmitted. When a background or a character is also displayed on the variable display unit 9, control is performed so that display control command data corresponding to the background or character is transmitted to the display control board 80.

All symbols stop waiting processing (step S30)
5): Control is performed so that all symbols displayed on the variable display section 9 are stopped after a predetermined time has elapsed. Also, control is performed so that the left and right symbols are stopped at a predetermined timing until the timing of stopping all symbols. Further, control is performed so that display control command data corresponding to a background or a character displayed on the variable display unit 9 is transmitted to the display control board 80 as appropriate.

Big hit display processing (step S306):
If the stop symbol is a combination of jackpot symbols,
The display control command data of the jackpot display is controlled to be sent to the display control board 80, and the internal state (process flag) is updated so as to shift to step S307. Otherwise, the internal state is changed to step S3.
Update to shift to 09. The combination of the big hit symbols is a combination in which the right and left middle symbols are aligned.
Further, the display control CPU of the game control board 80 displays a big hit on the variable display unit 9 according to the display control command data. The jackpot display is made to notify the player of the occurrence of the jackpot. Big winning opening opening process (step S307): Control for opening the big winning opening is started.
Specifically, while initializing counters and flags,
The large winning opening is opened by driving the solenoid 21.

Processing during opening of the special winning opening (step S30)
8): Control for transmitting display control command data of the special winning opening round display to the display control board 80, processing for confirming establishment of the closing condition of the special winning opening, and the like are performed. If the closing condition of the special winning opening is satisfied, the internal state is updated to shift to step S307 unless the end condition of the big hit gaming state is satisfied. If the jackpot gaming state end condition is satisfied, the internal state is updated to shift to step S309.

Big hit end processing (step S309):
A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flags and the like are returned to the initial state, and the internal state is updated so as to shift to step S300.

Embodiment 1 FIG. 11 is a flowchart of a determination random number update process (step S1) in the main process shown in FIG.
It is a flowchart which shows 0). In the determination random number update process, the CPU 56 increments the value of a counter for generating a random 1 (big hit determination random number) (step S1).
01). If the value of the counter for generating random 1, that is, the big hit determination counter is (maximum value + 1) (step S102), the counter value is reset to 0 (step S103). In this embodiment,
Since the random 1 has a value in the range of 0 to 299, (maximum value + 1) is 300.

Next, the CPU 56 checks whether or not the value of the big hit determination counter matches a predetermined value s (step S104). If they match, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted (step S105), and the extracted value is stored in a predetermined area of the RAM 55 (step S106). Hereinafter, the stored value is referred to as a stored value. The predetermined value s is set to, for example, an appropriate value (150 in this example) when the power is turned on. This value may be changed each time the power is turned on. In addition, prior to the update process of step S101, step S
In the case where the processing of step 104 is performed, if the initial value of the predetermined value s is set to 0, a period in which the value is 0 may continue for a while. Preferably, the value is not zero.

Further, the CPU 56 checks whether or not the value of the big hit determination counter matches the one-round determination value (step S107). The one-round judgment value will be described later.
If they match, the stored value is set as an initial value in the big hit determination counter (step S10).
8), the stored value is set as the one-round judgment value (step S10)
9).

The one-round judgment value is a value stored in a predetermined area of the RAM 55 and is used to determine the timing at which the value of the big hit judgment counter is updated to a random 6 value. When the jackpot determination counter starts advancing from a new initial value (the value when the stored value is set), the same value is set for the one-round determination value. Matches the one-round judgment value. That is, the one-round determination value is a value for detecting that the count of the big hit determination counter has completed one round. When turning on the power, the one-round judgment value is initialized to 0.

Next, the value of the counter for generating the random number 3 (the random number for determining the big hit symbol) is incremented by 1 (step S1).
30). If the value of the counter for generating random 3 is (maximum value + 1) (step S131), the counter value is reset to 0 (step S132). In this embodiment, (maximum value + 1) is 15.

FIG. 12 is an explanatory diagram showing an example of the value of the big hit determination counter that changes by the determination random number updating process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. It is memorized. That is, the value of random 6 is stored. In this example, the predetermined value s is 150, but the value can be set arbitrarily.

When the value of the big hit determination counter advances to "299", it is incremented by 1 and returns to 0 (step S).
101, S102, S103), and the processing of step S107 detects that the counter value matches the one-round determination value. Then, in the process of step S108, the stored value is set in the big hit determination counter. The stored value is also set as a one-round determination value at the same time (step S109). FIG.
In the example shown in FIG. 2, the stored value at this point is “19”. Therefore, from this point, the big hit determination counter starts
The process starts from the initial value “19”.

When the value of the big hit determination counter advances to the "predetermined value s" again, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the big hit determination counter reaches "19", the process proceeds to step S10.
In the process of 7, it is detected that the counter value matches the one-round judgment value. Then, in the process of step S108, the stored value of random 6 “195” is set as a new initial value in the big hit determination counter. Therefore, from this point, the big hit determination counter starts increasing from the initial value “195”.

When the value of the big hit determination counter reaches the predetermined value s again, random 6 (= P) is extracted and stored. Then, when the value of the big hit determination counter reaches “195”, the counter value matches the one-round determination value. Therefore, in the process of step S108, the stored random 6 value “P” is newly added to the big hit determination counter. Set as the initial value. Therefore, from this point on, the big hit determination counter starts increasing from the initial value “P”.

As described above, each time the value of the big hit determination counter makes one round (300 counts), a new initial value is set as the count value, and thereafter, the counter proceeds from that value. A counter for generating a random 1, that is, a counter for determining an initial value of a big hit determination counter (a counter for generating a random 6) is:
The count is incremented by the remaining time of the 2 ms interrupt processing (processing started by the periodic reset signal) executed by the CPU 56. The surplus time differs depending on the progress of the game, and is a random period. As a result, the generated random 6 value is also a random value, so that the initial value of the big hit determination counter also changes randomly.

That is, every time the value of the big hit determination counter makes one round, the counter starts to advance from a random initial value again. Then, even if the illegal board is connected to the main board 31 and the timing of updating the jackpot determination counter value is recognized based on the signal output from the main board 31, the timing at which the jackpot determination counter value becomes the jackpot determination value is determined. It is difficult to send an incorrect start winning signal to the main board 31 for the purpose. This is because according to this embodiment, the timing at which the big hit determination counter value becomes the big hit determination value has no regularity and is random.

Further, in this embodiment, as is clear from the example shown in FIG. 12, the extraction timing of random 6 used as a new initial value is not constant. Then, the randomness of the initial value of the big hit determination counter increases, and as a result, the timing at which the big hit determination counter value becomes the big hit determination value becomes more random.

Embodiment 2 In the above embodiment, the predetermined value s that determines the timing for extracting the random 6
Is a predetermined value, but the predetermined value s may be variable. For example, the predetermined value s may be set based on a predetermined random number.

FIG. 13 is an explanatory diagram showing random numbers (random 7) for determining the predetermined value s. The counter for generating the random number 7 is updated, for example, in an infinite loop in the main processing shown in FIG. That is,
In the main process shown in FIG. 5, after step S19, a process for incrementing a counter for generating random 7 by +1 is performed. Therefore, in this embodiment, the counter for generating random 7 is not synchronized with the counter for generating random 6.

FIG. 14 is a flowchart showing the judgment random number updating process (step S10) in this embodiment. Steps S101 to S109 and step S
The processing of 201 to S203 is the same as that of the first embodiment (Embodiment 1). However, in this embodiment, when the random 1 matches the one-round judgment value (step S107), the value of the counter for generating the random 7 is extracted (step S115), and the extracted value is set to a new predetermined value. The value is set to s (step S116).

FIG. 15 is an explanatory diagram showing an example of the value of the big hit determination counter which changes by the determination random number updating process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. It is memorized. That is, the value of random 6 is stored. Note that, also in this example, the initial value of the predetermined value s (the value at power-on) is 150.

When the value of the big hit determination counter advances to "299", it is incremented by 1 and the value returns to 0 (step S).
101, S102, S103), and the processing of step S107 detects that the counter value matches the one-round determination value. Then, in the process of step S108, the stored value is set in the big hit determination counter. Step S11
The random 7 is extracted in the processing of S5 and S116, and is set as a new predetermined value s. Here, the predetermined value s = 6
Suppose it reaches 5.

The value of the big hit determination counter is "predetermined value s".
Upon proceeding to, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the jackpot determination counter becomes “19”, it is detected in the process of step S107 that the counter value matches the one-round determination value. Then, in the process of step S108, the stored value of random 6 is set as a new initial value in the big hit determination counter, and the “predetermined value s” is updated. Here, it is assumed that the predetermined value s = 25.

When the value of the big hit determination counter reaches the predetermined value s again, random 6 (= P) is extracted and stored. Then, when the value of the big hit determination counter reaches “195”, the counter value matches the one-round determination value. Therefore, in the process of step S108, the stored random 6 value is set as a new initial value in the big hit determination counter. Is set. Further, a new predetermined value s is set based on the random number 7.

In this embodiment, the timing for extracting the value (random 6) for changing the initial value of the big hit determination counter varies more than in the first embodiment. As a result, the randomness of the initial value of the counter for generating random 1, that is, the initial value of the big hit determination counter is further increased, and the timing at which the value of the big hit determination counter becomes the big hit determination value becomes more random.

Embodiment 3 In each of the above embodiments,
Although the initial value is set every time the value of the big hit determination counter makes one round, the initial value may be set after a predetermined round. At this time, the number of turns for setting the initial value may be variable. For example, the number of turns may be set based on a predetermined random number.

FIG. 16 is an explanatory diagram showing random numbers (random 8) for determining the number of turns n. The counter for generating the random number 8 is also updated by the random 1 initial value determination counter updating process (step S1) in the main process shown in FIG.
6, S19). In other words, in the main processing, while being updated at least once,
It keeps updating in an infinite loop. In this example, the range that the random 8 can take is 1 to 4, but the range is arbitrary.

FIG. 17 is a flowchart showing the judgment random number updating process (step S10) in this embodiment. Steps S101 to S107 and step S
The processing in steps 201 to S203 is the same as in the first embodiment. However, in this embodiment, random 1
Is equal to the one-round judgment value (step S107),
The value of the number-of-laps counter is incremented by one (step S12).
5). Then, when the value of the number-of-turns counter matches the number of turns n (step S126), the processing of step S108 and subsequent steps is executed. The round number counter is a counter that counts the number of rounds counted by the big hit determination counter. When the power is turned on, the number of rotations n is, for example, “1”.
Is set. The number of revolutions counter is set to 0 when the power is turned on.
Cleared.

That is, the value of the number-of-laps counter is n
If the value matches the stored value, the stored value is set as a new initial value in the jackpot determination counter (step S108), and the stored value is set to the one-round determination value (step S1).
09), a counter value for generating a random 8 is extracted (step S121). Then, the value of the extracted random 8 is set as the number of turns n (step S12).
2), the number-of-laps counter is cleared (step S12)
3). Therefore, when the big hit determination counter makes n rounds, a new round number n is set based on the random number 8.

FIG. 18 is an explanatory diagram showing an example of the value of the big hit determination counter which changes by the determination random number updating process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. It is memorized. That is, the value of random 6 is stored. Note that, also in this example, the initial value of the predetermined value s (the value at power-on) is 150.

When the value of the big hit determination counter advances to "299", it is incremented by 1 and the value returns to 0 (step S).
101, S102, S103), it is detected in the processing of step S107 that the counter value matches the one-turn determination value, and the value of the number-of-turns counter matches the number of turns n (number of turns n = 1 when the power is turned on). .). Then, in the process of step S108, the stored value is set in the big hit determination counter. Steps S121 and S122
, Random number 8 is extracted and set as a new number of rounds n.

Thereafter, when the value of the big hit determination counter reaches n times, the stored value is set in the big hit determination counter in the process of step S108. Further, random 8 is extracted in the processing of steps S121 and S122, and is set as a new number of rounds n. Here, the stored value is "19
5 ".

When the value of the big hit determination counter reaches the predetermined value s again, random 6 (= P) is extracted and stored. After that, the value of the big hit determination counter becomes n
Then, in step S108, the stored value is set in the big hit determination counter. Step S121
The random number 8 is extracted in the processing of S122 and is set as a new number of rounds n.

As described above, in this embodiment, the initial value of the big hit determination counter is not set every time the counter value makes one rotation, but is set when the counter value makes n rotations. Also, the value of n is not constant. Therefore, it becomes more difficult to externally predict the timing at which the value of the big hit determination counter matches the big hit determination value.

Note that the initial value is updated when the value of the big hit determination counter goes n times as in this embodiment, and a random 6 is extracted as in the second embodiment (Embodiment 2). And a form in which the predetermined value s for determining the timing for performing the operation is made variable.

Embodiment 4 In each of the above embodiments,
The value of random 6 extracted when the value of the jackpot determination counter reached the predetermined value s was used as it was as the initial value of the jackpot determination counter. However, some operation may be performed on the extracted random value 6, and the operation result may be used as the initial value.

FIG. 19 is a flowchart showing a judgment random number updating process (step S10) in a case where the result obtained by performing an addition operation on the extracted random 6 is used as an initial value. The processing in steps S101 to S107 and steps S201 to S203 is the same as in the first embodiment.

In this embodiment, when the value of the big hit determination counter matches the one-round determination value in step S107, the CPU 56 extracts a value of random 6 again (step S130). Then, the extracted value and the stored value are added (step S131). Next, the addition result is set as an initial value in the big hit determination counter (step S132). Note that the added value is 300
When this is the case, a value obtained by subtracting 300 is set.

FIG. 20 is an explanatory diagram showing an example of the value of the jackpot determination counter that changes by the determination random number updating process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. It is memorized. That is, the value of random 6 is stored. In this example, the predetermined value s is 150 as well.

When the value of the big hit determination counter advances to "299" and is incremented by one to return to 0, it is detected that the counter value matches the one-round determination value. Then, the value of random 6 is extracted in the process of step S130.
Here, it is assumed that the extracted value is “125”. Also,
It is assumed that the stored value is “19”. Therefore, the added value “144” of the stored value and the extracted value is set in the big hit determination counter. Therefore, from this point on, the big hit determination counter starts increasing from the initial value “144”.

When the value of the big hit determination counter reaches the "predetermined value s" again, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the big hit determination counter becomes “144”, it is detected that the counter value matches the one-round determination value. Then, the value of random 6 is extracted in the process of step S130. Here, it is assumed that the extracted value is “186”. The stored value is “195”. Therefore, the added value of the stored value and the extracted value is “381”, but the range that the random 1 can take is 0 to 299.
"1" is set in the big hit determination counter. Therefore, from this point, the big hit determination counter starts counting the initial value “81”.
Will start from.

When the value of the big hit determination counter advances to the "predetermined value s" again, random 6 (= P) is extracted and stored. When the value of the jackpot determination counter reaches "81", the counter value matches the one-round determination value, so that the stored value and the extracted value are added, and the addition result "P" is set to the new initial value in the jackpot determination counter. Is set as
Therefore, from this point on, the big hit determination counter starts increasing from the initial value “P”.

As described above, in this embodiment, since each value of random 6 extracted at a plurality of timings is subjected to addition processing to be the initial value of the big hit determination counter, the initial value is complicated. It is determined through the process. Therefore, it is still more difficult to externally predict the timing at which the value of the jackpot determination counter matches the jackpot determination value.

In this embodiment, the addition processing is used as the calculation processing, but the calculation is not limited to the addition.
Subtraction or multiplication may be used, or any other operation may be used. Further, the initial value is updated when the value of the big hit determination counter is n times as in the third embodiment, or a predetermined value for determining the timing for extracting the random 6 as in the second embodiment. A form in which the value s is made variable may be used in combination.

Embodiment 5 FIG. In each of the above embodiments,
The value of random 6 was extracted while the value of the jackpot determination counter made one round.
May be extracted. Further, the number of rounds of the count for setting the initial value may be made variable. FIG. 21 is a flowchart showing such a determination random number updating process (step S10) in the fifth embodiment. In this example, when the big hit determination counter makes n rounds, a value of random 6 is extracted, and the big hit determination counter becomes m.
When the circuit goes around, the initial value is set in the big hit determination counter.

The processes in steps S101 to S109 and steps S201 to S203 are the same as those in the first embodiment. In this embodiment, whether the value of the big hit determination counter is a predetermined value s is determined. The determination (step S104) is performed only when the value of the number-of-laps counter is a multiple of n (step S14).
0).

Therefore, when it is detected in step S107 that the value of the big hit determination counter has made one round, the value of the round number counter is incremented by one (step S141).
Also, the initial value updating process of steps S108 and S109 is executed only when the value of the number-of-laps counter is m (step S142).

FIG. 22 is an explanatory diagram showing an example of the value of the big hit determination counter that changes by the determination random number updating process shown in FIG. As shown in FIG. 21, when the count of the big hit determination counter reaches the n-th round, step S
When the determination at 140 becomes “Yes” and the counter value advances to “predetermined value s”, the value of random 6 is extracted and stored. In this example, the predetermined value s is 150, but the value can be set arbitrarily.

Then, on the m-th cycle of the count of the big hit determination counter, the value of the big hit determination counter advances to “299”, is incremented by 1 and returns to 0, and the determinations in steps S107 and S142 are “Yes”. . Then, in the process of step S108, the stored value is set in the big hit determination counter. The stored value is also set as a one-round determination value at the same time (step S109). In the example shown in FIG. 22, the stored value at this point is “195”. Therefore, from this point, the big hit determination counter starts counting the initial value “19”.
5 ”.

When the big hit determination counter advances n rounds again to reach the "predetermined value s", a random 6 is extracted and stored. Here, it is assumed that the extracted value is “P”. Then, when the value of the big hit determination counter reaches “195” on the m-th cycle of the count of the big hit determination counter, the stored random value “P” is set as a new initial value in the big hit determination counter. You. Therefore, from this point on,
The big hit determination counter advances from the initial value “P”.

As described above, in this embodiment, the extraction of the random number 6 as the initial value of the big hit determination counter and the setting of the initial value are executed when the count of the big hit determination counter reaches a predetermined number. Further, it is preferable that the predetermined cycle related to the extraction of the random 6 and the predetermined cycle related to the setting of the initial value are different. As described above, even if the extraction of the random number 6 and the setting of the initial value are performed at intermittent timings, since the initial value of the big hit determination counter changes randomly, the value of the big hit determination counter is externally changed to the big hit. It becomes difficult to predict the timing that matches the determination value. In this embodiment, the timing of extracting the random number 6 and the timing of setting the initial value can be set to timings that are temporally separated from each other as compared with the above embodiments.

In this embodiment, n and m are fixed values, but they may be variable values. For example, a random number corresponding to each may be extracted and changed according to the extracted random number value. In this case, the timing of the extraction of the random number 6 and the setting of the initial value further vary, so that it becomes more difficult to predict the timing when the value of the big hit determination counter matches the big hit determination value.

Embodiment 6 FIG. In the fourth embodiment (Embodiment 4) shown in FIG. 19 and FIG. 20, the stored value of one random 6 and the extracted value of random 6 when the big hit determination counter makes one round are determined by a predetermined value. Although the arithmetic processing is performed and the arithmetic result is set as the initial value of the big hit determination counter, a plurality of stored values may be used.

FIG. 23 is an explanatory diagram showing an example of a change in the value of the big hit determination counter when two stored values are used.
In this example, two predetermined values s1 and s2 for determining the timing at which the random 6 is extracted are used, and are set to “150” and “250”, respectively, which are predetermined.
Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s1”. It is memorized. further,
When the counter value advances to “predetermined value s2”, the value of the random 1 initial value determination counter is extracted and stored.

When the value of the big hit determination counter advances to "299" and is incremented by one to return to 0, it is detected that the counter value matches the one-round determination value. Here, the value of random 6 is extracted again. Here, it is assumed that the extracted value is “125”. It is also assumed that the stored values are “19” and “151”. Therefore, the addition value “295” of the stored value and the extracted value is set in the big hit determination counter. Therefore, from this point on, the big hit determination counter starts increasing from the initial value “295”.

When the value of the big hit determination counter advances to the "predetermined value s1" again, random 6 is extracted and stored.
Here, it is assumed that the stored value is “195”.
Furthermore, when the counter value has advanced to “predetermined value s2”, the value of the random 1 initial value determination counter is extracted and stored. It is assumed that the stored value is “145”. When the value of the big hit determination counter reaches “295”, it is detected that the counter value matches the one-round determination value. Then
The value of random 6 is extracted. Here, the extracted value is “1”.
86 ". The stored values are “195” and “145”. Therefore, the added value of the stored value and the extracted value is “526”, but the possible range of the random 1 is 0 to 299.
"6" is set in the big hit determination counter. Therefore, from this point, the big hit determination counter starts counting the initial value “22”.
6 ”.

When the value of the big hit determination counter advances again to "predetermined value s1" and "predetermined value s2", random 6 (= P2, P1) is extracted and stored. When the value of the jackpot determination counter reaches “226”, the counter value matches the one-round determination value, so the stored value and the extracted value are added, and the addition result “R” is set to the new initial value in the jackpot determination counter. Is set as Therefore, from this point on, the big hit determination counter starts increasing from the initial value “R”.

As described above, in this embodiment, since the addition processing is performed on each value of the random 6 extracted at the three timings to obtain the initial value of the big hit determination counter, the initial value is complicated. It is determined through the process. Therefore, it becomes more difficult to externally predict the timing at which the value of the big hit determination counter matches the big hit determination value.

In this embodiment, the addition processing is used as the calculation processing, but the calculation is not limited to the addition.
Subtraction or multiplication may be used, or any other operation may be used. Further, a mode in which the initial value is updated when the value of the big hit determination counter makes n rounds as in the third embodiment may be used together.

Embodiment 7 FIG. In the above embodiment, the predetermined value s that determines the timing for extracting the random 6
Although 1,1 and s2 are predetermined fixed values, the predetermined values s1 and s2 may be variable. FIG. 24 shows that the predetermined values s1 and s
It is explanatory drawing which shows the example of a change of the value of the big hit determination counter when 2 is set to "20" and "200".

As shown in FIG. 24, the same processing as in the sixth embodiment (sixth embodiment) is performed from the first round to the (n-1) th round of the count of the big hit determination counter. On the n-th lap, the value of the big hit determination counter becomes “predetermined value s1”.
= 20 "and" predetermined value s2 = 200 ", random 6 (= P1, P2) is extracted and stored. And if the count on the nth lap starts from “S”,
When the value of the big hit determination counter becomes "S" again, the value of random 6 is extracted, and the extracted value and the stored value P1,
The calculation for P2 is performed, and the calculation result T is set as the initial value T in the big hit determination counter.

In this case, in a mode in which arithmetic processing is performed on each value of the random 6 extracted at three timings to set the initial value of the big hit determination counter, a specific round of the count of the big hit determination counter is performed. Since the extraction timing of the random 6 is different, the initial value goes through a more complicated calculation process, and the initial value of the big hit determination counter becomes more random.

Although n is a fixed value in this embodiment, n may be a variable value corresponding to a random number, for example. Further, the number of times of random 6 extraction may be changed in a specific round of the count of the big hit determination counter. That is, the number of stored values may be changed.

As described above, in each of the above embodiments,
When the count value of the jackpot determination counter reaches a predetermined value, random 6 is extracted and stored. When the count of the jackpot determination counter circulates a predetermined number of times, the stored random 6 value is set as the initial value in the jackpot determination counter. I do. Therefore, as shown in FIG. 12, for example, the extraction timing of random 6 used as a new initial value is not constant. Then, the randomness of the initial value of the counter for generating random 1, that is, the initial value of the big hit determination counter increases, and as a result, the timing at which the big hit determination counter value becomes the big hit determination value becomes more random, making it difficult to predict from the outside. It will be.

Note that the gaming machine of each of the above-described embodiments, that is, the pachinko gaming machine shown in the front view of FIG. 1, has a special symbol that is variably displayed on the variable display section 9 based on a winning start. Although it was a first-class pachinko game machine in which a predetermined game value could be given to a player when a predetermined combination of symbols was obtained, a predetermined area was determined when an electric accessory opened in accordance with a start winning prize entered a predetermined area. Winning a second-class pachinko gaming machine in which a game value can be given to a player, and a predetermined electric role that is opened when a stop symbol of a symbol variably displayed based on a winning start is a predetermined symbol combination. The present invention can be applied to a third-type pachinko gaming machine in which a predetermined right is generated or continued when there is a certain right.

The means for realizing the variable display section 9 may be any means, for example, a variable display device such as a CRT or LED, or a drum type or belt type variable display device.

In each of the above embodiments, the main process shown in FIG. 5 is started by a periodic reset signal supplied from outside the CPU 56. However, the main process shown in FIG. The present invention is also applicable to a case where the main processing is executed by an interrupt or the like.

[0131]

As described above, according to the present invention, the value of the initial value determination counter is extracted from the gaming machine under the condition that the value of the specific game determination counter has reached the predetermined value, and the value is extracted. The value of the completed initial value determination counter is set as the initial value in the specific game determination counter every predetermined round of the specific game determination counter, so that the game control means synchronizes with the predetermined start timing. Even when observing the various signals that are output, it is no longer possible to estimate the timing at which the value for the specific game determination matches the determination value, and as a result, it is possible to give a signal from outside to illegally generate a big hit There is an effect that illegal play can be effectively prevented.

When the value of the initial value determination counter is configured to be updated in an infinite loop, the randomness of the value of the initial value determination counter increases, so that the value for the specific game determination is changed to the determination value. This has the effect that it is more difficult to externally estimate the timing that coincides with.

When a value determining means for determining a predetermined value of the specific game determination counter serving as a condition for extracting the value of the initial value determination counter is provided, the extraction timing of the update initial value is determined. Since the variation further varies, the initial value of the counter for specific game determination further varies, and it is more difficult to externally estimate the timing at which the numerical value for specific game determination matches the determination value.

If the value for determining the predetermined value of the specific game determination counter serving as a condition for extracting the value of the initial value determination counter is configured to be updated in an infinite loop, By increasing the randomness of the initial value extraction timing, there is an effect that it becomes more difficult to externally estimate the timing at which the numerical value for the specific game determination matches the determination value.

When the initial game setting counter is provided with initial setting timing determining means for determining a predetermined lap as a condition for setting an initial value in the specific game determining counter, the initial value setting timing varies more temporally. This has the effect that it is more difficult to externally estimate the timing at which the numerical value for the specific game determination matches the determination value.

When the numerical value for determining the predetermined lap is updated in an infinite loop, the dispersion of the initial value setting timing becomes larger, and the numerical value for the specific game determination becomes the determination value. There is an effect that it is more difficult to externally estimate the coincident timing.

The predetermined value of the specific game determination counter, which is a condition for extracting the value of the initial value determination counter, is set to a value within the count range of the specific game determination counter when the power is turned on. With this configuration, a situation in which the extraction timing of the initial value determination counter value exceeds the count range of the specific game determination counter and cannot be extracted can be avoided.

The value of the initial value determining counter is extracted at a plurality of predetermined timings, and the arithmetic processing is performed by using each value of the extracted initial value determining counter for each predetermined round of the specific game determining counter. When the result is configured to be set as an initial value in the specific game determination counter, the updated initial value becomes more complicated, and a signal for generating a big hit from outside may be given. This has the effect of preventing illegal playing more effectively.

In the case where the plurality of predetermined timings include a case where the count of the specific game determination counter has made one round and a case where the value of the specific game determination counter has reached the predetermined value, the initial value is set. There is an effect that the irregularity of the count value extraction timing of the determination counter becomes larger, and it becomes more difficult to externally estimate the timing at which the value for the specific game determination matches the determination value.

If the range in which the value of the specific game determination counter can take is the same as the range in which the value of the initial value determination counter can take, the probability of transition to the specific game state changes. There is no effect.
