Abstract

PROBLEM TO BE SOLVED: To prevent an illicit operation carried out by attaching an illicit substrate to a game control device arranged in a game machine for selecting a special game condition and the like. SOLUTION: In this game machine, a determination counter Hc value in at least a volatile memory is not initialized according to a clear signal based on a clearing operation (S130). Consequently, even when a false counter Gc, which causes a false power source drop and emits a false clear signal by illicit software to start counting of the determination counter Hc value from zero after the clear signal, is used, the false counter Gc gives a value different from that of the determination counter Hc, so that generation of the special game condition can be prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to preventing fraudulent acts by attaching a fraudulent board to a gaming control device for selecting a special gaming state or the like provided in a gaming machine.

[0002]

2. Description of the Related Art Conventionally, a pachinko machine as a game machine,
A symbol display capable of variably displaying a plurality of symbols is arranged almost in the center of the game area. Then, when the game ball wins the prize hole, the prize ball is paid out, the start prize hole is won, and the game ball detector generates a game ball detection signal to pass the specific area, and the symbol is displayed by the signal. There is a type in which the design of the container is variably displayed. This kind of pachinko machine is, as shown in FIG. 9, mainly a game control device, a display control device for controlling the symbol display of the symbol display device, a game ball detector for generating a game ball detection signal, a power supply board, a relay board. Etc. This game control device has a CPU (CENTRAL P
A ROM (READ ONLY MEMORY) for storing the ROCESSOR UNIT) and the game program, a volatile memory held by a backup power source, etc. in preparation for a voltage drop due to a power failure or the like. Further, the display control device displays the symbol on the liquid crystal symbol display in response to the signal from the CPU.

A voltage drop detection circuit for detecting a voltage drop with respect to a preset voltage is mounted on the power supply board, and this voltage drop signal is output to the terminal "P". Also,
When a clear button (not shown) is pressed (clear operation), a clear signal is issued, and the clear signal is set to the terminal "Q". In addition, the "R" terminal of the power supply board is a backup power supply terminal of the game control device, ram memory, etc., and the "S" terminal of the power supply board is
This is the terminal for the reset signal.

Then, the pachinko machine having the above structure causes a special game state based on a well-known determination method.
One method thereof will be described with reference to FIG. 10 showing the concept of processing by interrupt processing or the like. The judgment counter H
Values such as c are stored in volatile memory whose values are held by the backup power supply. FIG. 10A is a control flow chart for processing the “voltage drop”, and it is judged whether or not the voltage drop has occurred depending on the state of the terminal “P” (S10).
0) When a voltage drop occurs, the voltage drop signal is changed from “OFF” to “ON” with a delay of Ta from the time of detection, and the reset signal is changed to “O” with a delay of time Tc.
The flag F is changed from "FF" to "ON" and the flag F is set to "1" (S101). Based on this reset signal, the game control device (CPU) detects the state of the detector and the like.

On the other hand, the "voltage" is restored (or power is turned on).
If so, it is determined whether or not the flag F is "1" (S102). This judgment is made immediately after the voltage is restored.
It is determined whether or not a "clear operation" described later has been performed, and when the flag F is not "1", the following processing is not executed. Then, the flag F is set to "0" (S1
03), it is determined whether or not the clear signal is "ON" (S104), and when the clear operation is performed, the contents of the volatile memory including the determination counter Hc are initialized (S105). This volatile memory initialization can be executed by turning on the power while executing the clear operation, and even if the clear operation is performed when the power is normal at other timings, the initialization is performed. Not be converted.

FIG. 10 (B) is a control flow for executing a game program forming a determination counter Hc for jackpots, and interrupt processing is performed every predetermined time (2 ms) starting from a clear signal generated by a clear operation. hand,
1 is added (S110). The determination counter Hc corresponds to the probability of the special gaming state, for example, 1 / H
0 to 9 for the probability of m (here, 946)
In order to make a circulation counter of 46 (number), when the determination counter Hc reaches 946, it is set to "0" (S11).
2, S113). Further, the game control device generates a pulse signal every 2 ms for adding 1 to this determination counter Hc, and this pulse signal is output to the terminal a of the display control device through the terminal A of the game control device, and the symbol display While taking the timing of the symbol display on the container, the other terminals are used for signals such as the selection of the display symbol.

FIG. 10 (C) is a jackpot determination processing flow, in which a game ball is detected by a game ball detector when it enters a starting winning port installed in a game region and passes through a specific region, and this game is detected. The ball detection signal is the terminals C and D of the game ball detector.
It is output to the terminals c and d of the relay board via, and the output signal from the relay board is further output to the game control device. Then, the value of the determination counter Hc at the time of the fall of this game ball detection signal is stored, and it is determined whether or not this stored value causes a special game state, and a symbol is displayed on the display control device (symbol display device). Send a signal to start the fluctuation. When the stored value is a specific value (for example, "7"), after a predetermined time, the same symbol (special symbol) is confirmed and displayed on the symbol display unit, and a jackpot that is advantageous to the player (special game state) Is caused (S120, S121).

[0008]

FIG. 11 shows a circuit configuration when an illegal board having a pu for storing cpu or illegal software as an illegal means is added to the back surface of a relay board, for example. . The output signal from the terminal A of the game control device is input through the terminal A ′ of the illegal board, the terminals C and D of the game ball detector are removed from the relay board, and the terminals C ′ and D of the illegal board are removed. , And the terminals e and f of the illegal board and the terminals c and d of the relay board. Also, a terminal "P" for outputting a voltage drop of the power supply board,
The terminals "Q" of the clear signal are connected as terminals P'and Q ', respectively.

It has been previously investigated that the specific value of the special game state is "7" as a premise for carrying out this fraudulent act in the above-mentioned configuration circuit. Then, the player plays the game as usual, but, for example, by operating the pseudo power supply drop and the pseudo clear signal, illegal software that causes a special game state as described below is executed. (1) First, the cpu of the illegal board outputs the fact that it is a pseudo voltage drop of the power supply board to the terminal "P" via the terminal P ', and the game control device shows the above-mentioned FIG. 10 (A). The "voltage drop process (S101)" is executed. (2) Next, after a predetermined time, the cpu of the illegal board outputs a signal for restoring the pseudo voltage to the terminal “P” via the terminal P ′, and also clears the pseudo to the terminal Q via the terminal Q ′. Send a signal. The game control device executes the processing (S103 to S105) shown in FIG. 10A, and the determination counter Hc is initialized.

(3) Then, based on the pseudo clear signal, the cpu of the illegal board receives a pulse signal generated every 2 ms for adding 1 to the determination counter Hc via the terminal A of the game control device, and pseudo. By performing the process of adding 1 to the counter Gc, the value of the pseudo counter Gc and the value of the determination counter Hc can be made the same value. (4) Assuming that the game ball is detected by the game ball detector just before the value of the pseudo counter Gc becomes “7”, the falling signal is sent from the terminals e and f of the illegal board to the terminal c of the relay board. output to d.

(5) When the falling signal generated at the terminals c and d is received, the flow shown in FIG.
Since the value of the determination counter Hc is read, this falling signal is regarded as the game ball detection signal is output from the game ball detector and is processed to generate a special game state (big hit). In other words, the cpu of the illegal board creates a pseudo voltage drop signal and then issues a pseudo clear signal to utilize the initialization of the decision counter Hc, thereby determining the value of the decision counter Hc and the value of the pseudo counter Gc. Can be made the same, and at the timing of a big hit, it is possible to cause a big hit by causing a falling signal that is regarded as a game ball detection signal from the game ball detector.

As described above, the illegal software on the illegal board can generate a big hit (special game state) by artificially issuing a power drop and a clear signal. Therefore, by generating these pseudo signals at appropriate intervals, it is possible to maintain a normal gaming state without continuous occurrence of special and big hits. Since it is impossible to determine whether or not the illegal board is small, it cannot be easily found from the back surface of the gaming machine whether or not the illegal board is attached. Therefore, the present invention provides a gaming machine capable of preventing fraudulent activity even if such a fraudulent board is attached.

[0013]

According to a first aspect of the present invention, there is provided a game ball detector for detecting that a game ball has passed through a specific area, a clear signal generated by a clear operation, and added every predetermined time. Judgment counter Hc used for jackpot judgment
With a volatile memory that holds the value of the judgment counter etc. by the backup power supply, when the game ball is detected by the game ball detector, the judgment counter judges whether or not to generate a jackpot that is advantageous to the player. . Therefore, at least the value of the judgment counter Hc in the volatile memory is not initialized on the basis of the clear signal by the clear operation. Therefore, the pseudo power supply drop and the pseudo clear signal by the illegal software are issued to clear the value of the judgment counter Hc. Even if the pseudo counter Gc that counts from "0" is adopted later, the pseudo counter Gc has a different value from the determination counter Hc, so that it is possible to prevent the special gaming state from occurring.

According to a second aspect of the present invention, a game ball detector for detecting that a game ball has passed a specific area, a clear signal generated by a clear operation, and a clear signal generated at a predetermined time are added every predetermined time and used for a jackpot judgment. It has a counter Hc and a volatile memory that holds values such as a judgment counter by a backup power supply. When the game ball is detected by the game ball detector, the judgment counter determines whether or not to generate a jackpot that is advantageous to the player. to decide. Therefore, the value of the determination counter Hc in the volatile memory is initialized based on the clear signal by the clear operation, but the value of the determination counter Hc for determining the jackpot is not adopted a specific value immediately after the clear signal. Therefore, even if a pseudo counter Gc that outputs a pseudo power supply drop and a pseudo clear signal by illegal software and counts the value of the judgment counter Hc from "0" after the clear signal is adopted, the pseudo counter Gc does not Since it becomes a value different from Hc, it is possible to prevent the special game state from occurring.

A gaming machine according to a third aspect of the present invention is a game ball detector for detecting that a game ball has passed a specific area, a clear signal generated by a clear operation, and a judgment signal used for judgment of a big jackpot, added every predetermined time. It has a counter Hc and a volatile memory that holds values such as a judgment counter by a backup power supply. When the game ball is detected by the game ball detector, the judgment counter determines whether or not to generate a jackpot that is advantageous to the player. to decide. Then, the determination counter Hc is initialized based on the clear signal, but by ignoring the signal from the game ball detector immediately after the clear signal has occurred, the occurrence of the special game state can be prevented.

The gaming machine according to claim 4 is provided with a sub-counter Ic whose number is in the same range as the judgment counter Hc, and when the value of the judgment counter Hc reaches the update value α, the judgment counter Hc.
It is difficult to predict the value of the judgment counter Hc by setting the value of c to the value of the sub counter Ic and the value of the sub counter Ic to the judgment counter Hc and the update value α, and to prevent fraud. You can

BEST MODE FOR CARRYING OUT THE INVENTION A pachinko machine as a game machine is of a well-known type, and the description of the same functions and the like as the conventional one is omitted, and a front view shown in FIG. 1 and a control flow shown in FIGS. It will be described with reference to the drawings. A liquid crystal display type symbol display L for playing a variable display game through a plurality of variable symbols is arranged in substantially the center of the game area 19, and this symbol display L is arranged in a game control device described later. Installed CPU (CENT
RAL PROCESSOR UNIT) and the display control device connected to the game control device, the symbol display portion L
1-L3 can be displayed separately, and the design is "0-9, AF"
Are variably displayed in this order.

Further, the left and right sides of the symbol display L are provided with normal symbol starting gates 23a and 23b, and when the game ball passes, a regular symbol display 5 attached to a large prize winning device 58 described later.
The symbol 6 starts changing and stops after a predetermined time has elapsed, and when the fixed symbol coincides with a preset symbol, it becomes a hit, and the normal electric auditors product 57 is opened for a predetermined period of time. The control flow for determining the "hit" is performed via a hit counter FRND, as shown in FIG. The hit counter FRND is executed by an interrupt every 2 ms, and 1 is added to the hit counter FRND (S
91), the hit counter FRND is Ha (here, 12
It is set to 8) (S92), and when it reaches 128, it is set to 0 (S93). That is, the hit counter FRND is incremented by 1 every 2 ms.
It is a circulation number of 127.

Further, it is determined whether or not the game ball has passed through the normal symbol starting gates 23a and 23b (S94), and when it has passed, the hit counter FRND is read, and FR is read.
The data is stored in ND1 to ND4 (S95). And the FRN
It is determined whether or not the value stored in D1 to 4 is the winning value "7" (S96). When the value is "7", the winning process is performed (S97). Then, while the normal electric auditors role item 57 accompanying the hit is opened for a predetermined time, the game ball is the normal electric auditors role object 5
When the player wins 7 and passes through a specific area, a game ball detector (not shown) that detects the winning ball generates a game ball detection signal, and a special game state (big hit) described in detail later.
It is determined whether or not to occur.

Further, this pachinko machine is a game control device having the same structure as the conventional one, a display control device for controlling the symbol display of the symbol display device, a game ball detector for generating a game ball detection signal,
It is equipped with a relay board and the like. And this game control device has a CPU (CENTRAL PROCESS RUNUNI
T) and a ROM (READ ONLY MEMORY) storing a game program capable of preventing fraudulent activity
Is equipped with. Further, the volatile memory retains the stored value via the backup power supply even if a voltage drop occurs.

Further, the game control device is provided with a periodic signal generated every 2 ms for interrupt processing, and this periodic signal is the time during which the entire game program can be executed. It is made executable to be shorter than this time. Then, the cycle signal generated for each cycle time is output to the terminal a of the display control device via the terminal A of the game control device to keep the timing of the symbol display on the symbol display device and other terminals. Is used for signals such as selection of display symbols.

Next, matters relating to prevention of fraudulent acts on software stored in the ROM will be described.
It should be noted that the fraudulent act is the same fraudulent software as the conventional one, in which the fraudulent board shown in FIG.

(First Embodiment) As a countermeasure in this embodiment, the initial value of the determination counter Hc is set to a value other than "0" even if the clear signal (terminal "Q") is "ON". 3A, 3B and 3C showing the control flow of the concept and the timing of issuing the reset signal will be described with reference to FIG. 10D. The same numbers are attached to the steps that perform the same processing as in the conventional case.

FIG. 3A is a control flow chart for coping with the occurrence of a "voltage drop" with respect to a preset voltage due to a power failure or the like, and shows whether or not a voltage drop has occurred depending on the state of the terminal "P". Judgment (S100), if a voltage drop occurs, the voltage drop signal is changed from “OFF” to “ON” with a delay of time Ta from the time of detection, and the reset signal is “OFF” with a delay of time Tc. Is changed from "ON" to "ON" (see FIG. 10D), and the flag F is set to "1" (S101). Based on this reset signal, the game control device (CPU) detects the state of the detector and the like.

On the other hand, when the "voltage" returns to a predetermined voltage (or the power is turned on at the normal time), the flag F
It is determined whether or not is "1" (S102). It should be noted that this determination process is for determining whether or not a "clear operation" described later has been performed immediately after the voltage is restored. When the flag F is not "1", the following processing is not executed. Then, the flag F is set to "0" (S103), it is determined whether or not the clear signal is "ON" (S104), and when the clear operation is performed by pressing the clear button, at least the determination counter Hc is set. The contents of the volatile memory to be removed are initialized (S130). That is, the initialization of the value of the determination counter Hc is not performed, but the initialization of other variables (volatile memory) can be appropriately selected. It should be noted that, when this initialization is executed, it is possible to prevent fraud by notifying the fact via a speaker attached to the gaming machine or outputting it to a hall computer or the like and notifying a staff member of that fact.

FIG. 3 (B) is a control flow for executing a game program for forming a determination counter Hc for jackpots, which is interrupted every periodic signal (2 ms) and incremented by 1 (S110). . However, the determination counter Hc is set to a value other than "0" (not initialized) when the clear signal is turned "ON",
Even if 1 is added, it is configured so as not to be a number such as “1, 2, ...”. Note that it is desirable to select a different value each time through the lottery means or the like when selecting the initial value (value other than “0”).

The determination counter Hc corresponds to the probability of the special game state, for example, 1 / Hm (here, 9
For the probability of (46), the determination counter Hc is set to “0” when the determination counter Hc reaches 946 (S112, S113) in order to set a circulation counter of 0 to 946. or,
The game control device adds 1 to this determination counter Hc 2
A pulse signal is generated every ms, and this pulse signal is output to the terminal a of the display control device through the terminal A of the game control device, and the timing of the symbol display on the symbol display device is taken, as well as other terminals. Is used for signals such as selection of display symbols.

Next, explaining the flow shown in FIG. 3 (C), when the game ball wins the ordinary electric accessory 57 and passes through the specific area while the ordinary electric accessory 57 is opened for a predetermined time, Gaming ball detector (not shown) that detects the winning ball
Generates a game ball detection signal (falling signal from ON to OFF) and is output to terminals c and d of the relay board via terminals C and D of the game ball detector. Therefore, it is determined whether or not this falling signal is present (S120), and when it is determined, it is determined whether or not the value of the determination counter Hc (0 to 946 (Hm)) is a specific value (for example, "7"). (S121). Then, when it is a specific value, after a predetermined time, the same symbol (special symbol) is confirmed and displayed on the symbol display unit, and a special game state (big hit) that is advantageous to the player is generated.

On the other hand, the illegal software performs the following processing as in the conventional case. (1) First, the cpu of the illegal board outputs the fact that it is a pseudo voltage drop of the power supply board to the terminal "P" via the terminal P ', and the game control device shows in FIG. 3 (A). Execute the process. (2) Next, after a predetermined time, the cpu of the illegal board outputs a signal for restoring the pseudo voltage to the terminal “P” via the terminal P ′, and also clears the pseudo to the terminal Q via the terminal Q ′. Although the signal is sent, the game control device executes the processes (S103 to S105) shown in FIG. 3A, but the determination counter Hc is not initialized. (3) Based on this pseudo clear signal, cp of the illegal board
u receives a pulse signal generated every 2 ms for adding 1 to the determination counter Hc via the terminal A of the game control device and performs a process of adding 1 to the pseudo counter Gc. The value of this pseudo counter Gc is It differs from the value of the judgment counter Hc.

That is, when the clear signal is turned "ON", the initial value of the determination counter Hc is set to a value other than "0", and therefore the initial value of the determination counter Hc is detected by the unauthorized software. It is impossible to do.
Therefore, the value of the pseudo counter Gc and the value of the determination counter Hc cannot be the same. (4) As a result, assuming that the game ball is detected by the game ball detector just before the value of the pseudo counter Gc becomes "7", the falling signal is sent from the terminals e and f of the illegal board to the relay board. Even if the value is output to the terminals c and d and the value of the determination counter Hc is read, the value does not become the specific value "7" and the special game state (big hit) is not generated.

That is, since the unauthorized software cannot find the initial value of the judgment counter Hc even if it generates the pseudo voltage drop signal and then issues the pseudo clear signal, the value of the judgment counter Hc and the pseudo counter Gc are not found. The values of are different. As a result, based on the value of the pseudo counter Gc,
Even if a falling signal, which is regarded as a gaming ball detection signal being output from the gaming ball detector, is generated at the timing of the jackpot, the jackpot cannot be generated.

(Second Embodiment) As a countermeasure in the present embodiment, when the clear signal (terminal Q) is turned "ON", the initial value of the judgment counter Hc is set to "0".
However, the value of the determination counter Hc at the beginning of issuing the clear signal is a configuration in which “7” is excluded to prevent the occurrence of a big hit, and FIG. 4 showing a control flow of the concept.
This will be described with reference to (A), (B) and (C). Incidentally, the first
Steps that perform the same processing (FIGS. 3A, 3B, and 3C) as in the embodiment of FIG.

In FIG. 4A, the clear signal is "O".
N ”, the volatile memory (determination counter Hc
And the like) are initialized (“0”), and Ix indicating that there is a clear signal is set to “1” (S13).
1). It should be noted that, when this initialization is executed, it is possible to prevent fraud by notifying the fact via a speaker attached to the gaming machine or outputting it to a hall computer or the like and notifying a staff member of that fact. Then, in FIG. 4B, the determination counter Hc is interrupted for each periodic signal (2 ms), and 1 is added (S110). next,
It is determined whether Ix is "1" and the determination counter Hc is "7" (S140). In this case, the value of the determination counter Hc is set to "8" and Ix is set to "0". To the normal state from the next time (S14
1). That is, the value of the determination counter Hc immediately after receiving the clear signal does not adopt "7". On the contrary, when Ix is not "1", the determination counter Hc is normally executed so that the circulation number becomes 0 to 946 (S112, S113).

On the other hand, the unauthorized software creates a pseudo voltage drop signal and then issues a pseudo clear signal to find the initial value of the judgment counter Hc and determine the judgment counter Hc.
, And the value of the pseudo counter Gc match, the value of the determination counter Hc is “0, 1, ..., 6, 8,
There is no "7" like "9 ...". Therefore, based on the value (0, 1, ..., 6, 7, 8, 9, ...) Of the pseudo counter Gc, it is considered that the gaming ball detection signal has been output from the gaming ball detector immediately before it becomes “7”. Even if the down signal is generated, the value of the determination counter Hc is "8", and the big hit cannot be generated.

(Third Embodiment) As a countermeasure in the present embodiment, when the clear signal (terminal Q) is turned "ON", the initial value of the judgment counter Hc is set to "0". FIG. 5 is a diagram showing a control flow of the concept, which is configured to ignore the falling signal from the game ball detector at the beginning of the signal generation, to prevent the occurrence of a jackpot.
This will be described with reference to (A), (B) and (C). Incidentally, the second
Steps that perform the same processing (FIGS. 4A, 4B, and 4C) as in the embodiment of FIG.

In FIG. 5C, it is judged whether or not Ix is "1" (S144). When it is "1",
Ix is set to "0" (S145), and this processing ends. That is, the falling signal from the gaming ball detector immediately after the clear signal is ignored and it is not judged whether or not it is a big hit, but it is judged from the next time. on the other hand,
The unauthorized software creates a pseudo voltage drop signal and then issues a pseudo clear signal to find the initial value of the judgment counter Hc so that the value of the judgment counter Hc matches the value of the pseudo counter Gc. However, since the falling signal from the gaming ball detector immediately after the clear signal is ignored, the occurrence of a big hit can be prevented.

Next, means for preventing other illegal means will be described. This fraudulent means creates a pseudo counter Gc that is the same as the determination counter Hc for determining a big hit, based on a clear signal after the power is turned on, and detects a game ball just before reaching a specific value (for example, 7). A pseudo-fall signal is generated from the vessel to generate a big hit. Therefore, as a countermeasure, it will be described below.

(Fourth Embodiment) In this embodiment, the value of the determination counter Hc and the value of the pseudo counter Gc are made different so as to prevent the occurrence of an illegal special game state (big hit). Yes, it will be described with reference to FIG. First,
As shown in FIG. 6A, when there is a clear signal, a determination counter Hc for determining a big hit, a sub-counter Ic, which will be described later in detail, a counter counter i, and an update value α are initialized (S1, S2). ), The initialized pulse signal is output to the terminal a of the display control device through the terminal A of the game control device. Therefore, when the illegal board is attached, upon receiving this initialization signal, the cpu arranged on the illegal board initializes the pseudo counter Gc that adds 1 by the pulse signal.

After that, the control flow shown in FIGS. 6B and 6C is executed with the periodic signal (2 ms). First, the timer T is initialized. This timer T shows the concept of making it correspond to a periodic signal (S10). Next, 1 is added to the determination counter Hc (S11), and it is determined whether or not the determination counter Hc is the maximum value (Hm) (S1).
2) Initialize when the maximum value (Hm) is reached (S1)
3). By this processing, the determination counter Hc is 2 ms.
The number of circulation is 0 to 946 (Hm), which is incremented by 1 every time.

Next, 1 is added to the counting counter i (S
14). Then, this counting counter i is multiplied by the number of intervals I (integer), divided by the number of intervals I, and it is determined whether or not the value becomes the value of the counting counter i (S15). And
When the value reaches the value of the counting counter i, the subroutine (A) is executed. By the integer calculation (S15), it is possible to detect when the count counter i becomes every interval number I. Therefore, this interval number I is set to, for example, "3".
When set to, the subroutine (A) is executed every 6 ms.

In this subroutine (A), first, the counter counter i is initialized (S40). This initialization of the counting counter i makes it possible to execute the subroutine (A) for each interval number I in the addition processing and the integer calculation (S15) in step S14. Then, 1 is added to the sub-counter Ic (S41), and the sub-counter Ic becomes
It is determined whether or not it is the maximum value (Hm) of the determination counter Hc (S42), and when it is the maximum value (Hm), initialization is performed (S43). That is, this sub-counter Ic is a number in the same range as the determination counter Hc, but at every 6 ms (interval number I
= 3), 1 is added to each period signal (2 ms)
Is different from the counter Hc that is incremented by.

Next, returning to the game program, it is judged whether or not the judgment counter Hc is the updated value α (S17),
When the determination counter Hc is the updated value α, the value of the determination counter Hc is temporarily stored in the variable HH (S18),
The value of the sub-counter Ic is set to the determination counter Hc and the update value α, and the variable HH (the value of the determination counter Hc) is set to the value of the sub-counter Ic (S19). By this processing, thereafter, the determination counter Hc is executed from the value of the sub-counter Ic to the updated value α, and the sub-counter Ic is determined from the value of the determination counter Hc at every interval number I.
The addition process of 1 is performed.

That is, when the value of the judgment counter Hc becomes the updated value α, the values of the judgment counter Hc and the sub counter Ic are exchanged and the processing is performed thereafter. Therefore, the values of the judgment counter Hc and the pseudo counter Gc are initialized at the time of power-on. Even if the determination counter Hc is changed, the determination counter Hc and the pseudo counter Gc have different values, and the value of the determination counter Hc becomes difficult to guess, so that fraud prevention can be achieved.

Further, even if the value of the judgment counter Hc is replaced with the value of the sub counter Ic, the value of the sub counter Ic at that time is set to the update value α, so that the judgment counter Hc adds 1 to the update value α. Because it is done, 0-946
(Hm) has a uniform value and does not affect the selection of the big hit.

Then, the timer T judges whether or not Te (2 ms which is a periodic signal) has elapsed, and after the elapse, it returns to step 10 (S20). That is, since all processing of the game software is configured to be executable within the periodic signal time (2 ms), the periodic signal time is adjusted and the processing of the game program is executed every periodic signal time (2 ms). Let By the above simple process, the value of the determination counter Hc is set to 1 for each cycle signal from the time of power-on (clear signal).
Since it is not the circulation number to be added, the pseudo counter Gc (0 to 946 (H
m)) is a different value. As a result, the judgment counter H
Since the timing when c becomes a specific value (for example, “7”) is unknown, it is possible to prevent fraud.

(Fifth Embodiment) This embodiment is almost the same as the fourth embodiment, but FIG.
Only the control flow corresponding to (C) is different and will be described with reference to FIG. 7. In FIG. 7, steps having the same contents as in FIG. 6 will be outlined with the same reference numerals. First, the timer T is initialized (S10), and the determination counter Hc is set to 1
Is added (S11). Then, this determination counter Hc
Is determined to be the maximum value (Hm) (S12), and if it is the maximum value (Hm), initialization is performed (S13).

Next, it is judged whether or not the judgment counter Hc is the updated value α (S17). When the judgment counter Hc is the updated value α, the value of the judgment counter Hc is temporarily stored in the variable HH. (S18), the value of the sub counter Ic is set to the determination counter Hc and the update value α, and the variable HH (the value of the determination counter Hc) is set to the value of the sub counter Ic (S19). This process is the same as in the fourth embodiment.

Then, the timer T judges whether or not Te (periodic signal time of 2 ms) has elapsed, and returns to step 10 after the elapse (S20). The execution of (A) is repeated (S3
0). That is, since the entire processing of the game software is configured to be executable within the periodic signal time (2 ms), the subroutine (A) is repeatedly executed during the adjustment time of the periodic signal time.

Each time this subroutine (A) is repeatedly executed, the sub-counter Ic is incremented by 1 (S).
41). Since the period signal adjustment time is different in each execution process of the game program, the value of the sub counter Ic becomes an unknown value. Therefore, in the first embodiment, the sub-counter Ic is a number that is incremented by 1 for each interval number I, and the processing with regularity is performed, but in the second embodiment, it is random. It becomes a value and is replaced with the determination counter Hc (S19). As a result, the timing at which the determination counter Hc reaches a specific value (for example, "7") is not known more and more, and fraud prevention can be achieved.
Further, since the fifth embodiment can be executed without performing the process of the interval number I in the fourth embodiment,
There is an advantage that it can be easily configured.

(Sixth Embodiment) In the present embodiment, a game ball, for example, enters a starting winning opening, passes a specific area, and is detected by a game ball detector. This is for adding 1 to the sub-counter Ic,
A control flow formed on the basis of the fourth embodiment is shown in FIG. 8, and the same steps are denoted by the same reference numerals and the description thereof is omitted. That is, in the subroutine (A), the sub-counter Ic performs an addition process of 1 for each interval number I, and also performs an addition process of 1 every time the detection signal is turned "ON" (S5).
5, S56). As a result, even if the interval number I is a fixed value, the value of the sub counter Ic (determination counter Hc) is
Since addition processing is performed by a random detection signal, prediction cannot be performed.

Further, the subroutine (A) is processed by adjusting the interval signal time (2 m) for each interval number I (fourth embodiment).
s) is executed (fifth embodiment), processing is performed for each interval number I and the signal of the detector (sixth embodiment). It goes without saying that the processing may be performed by appropriately combining, for example, a combination of each interval number I and the adjustment period signal time (2 ms). Further, the sub-counter Ic is a process of adding 1 (S
41) but adding other numbers (eg 2),
Alternatively, a process in which the value of the sub-counter Ic is unpredictable, such as adding different numbers over time, may be performed.

Further, the first to third embodiments are countermeasures for causing an illegal special game state by issuing a pseudo voltage drop signal and a pseudo clear signal in the illegal software. The sixth embodiment is a countermeasure for causing an illegal special game state by configuring the value of the determination counter Hc and the value of the pseudo counter Gc to be the same in the illegal software. Therefore, in order to prevent a fraudulent act based on both, any one of the first to third embodiments may be appropriately combined with the fourth to sixth embodiments. In addition, although the above-mentioned form in which the illegal software is performed via the pseudo voltage drop signal and the pseudo clear signal is mentioned, depending on the model of the gaming machine, for example, there is a case where the initialization is performed only by the pseudo clear signal. Needless to say, the present invention can be appropriately modified and applied.

[0053]

Since the gaming machine of claim 1 does not initialize the judgment counter Hc based on the clear signal, even if the pseudo power supply drop signal and the pseudo clear signal are issued by the illegal software, the judgment is made as the pseudo counter Gc. Since the counters Hc have different values, it is possible to prevent the special game state from occurring. The gaming machine according to claim 2 initializes the determination counter Hc on the basis of the clear signal, but the value of the determination counter Hc for determining a big hit is configured not to adopt a specific value immediately after the clear signal. Even if the pseudo power supply drop signal and the pseudo clear signal are issued by the illegal software, the pseudo counter Gc has a value different from the determination counter Hc, so that it is possible to prevent the special gaming state from being caused. The gaming machine according to claim 3 initializes the determination counter Hc based on the clear signal, but by ignoring the signal from the gaming ball detector immediately after the clear signal occurs,
Occurrence of a special game state can be prevented. The gaming machine according to claim 4 is provided with a sub-counter Ic having the same range as the decision counter Hc, and when the value of the decision counter Hc reaches the update value α, the value of the decision counter Hc is set to the value of the sub-counter Ic. Then, the value of the sub-counter Ic is set to the determination counter Hc and the updated value α
By setting to, it becomes difficult to predict the value of the determination counter Hc, and fraud prevention can be achieved.
