Abstract

PURPOSE:To prevent an improper alteration by the third person, by a method wherein the values of random numbers inputted from a random number generator are not used as-inputted for the game, but the correlation between the inputted values and a group of values previously inputted, is judged, whether intentional values are present or not is judged, and only if normal, the values are inputted as random numbers. CONSTITUTION:In a CPU 10 functioning as a game controller, when the power source is turned on, to confirm whether a random number generator is alive or not, the values of random numbers are inputted by a random number input process and a special condition judging process is performed. In the random number input process, first, a selection signal is sent out so that the values of random numbers are inputted into the random number generator built in the CPU 10. Then, in the special condition judging process, whether a block to be the judging standard is finished or not is judged. If yes, whether the values of random numbers inputted this time and the values of random numbers inputted last time are the same or not is judged. If the same, 1 is added to the block memory region. Then, if the same values are inputted several times continuously, a game stopping process is performed to stop the game.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine control device, and more specifically, a game control device for performing game control and a random number generation device for generating uniform random numbers used in the game are separately configured. The present invention relates to a gaming machine control device.

[0002]

2. Description of the Related Art A conventional game program method for a game machine, particularly a ball game machine, is that an environment in which a game machine control device for controlling the game machine is installed, that is, a metal ball (game ball) is always It is installed in a circulating environment.
Therefore, noise is always generated due to the movement of the metal sphere. So, the program by noise (CPU)
As a countermeasure against runaway, the method of resetting the CPU at a certain fixed interval is adopted. Since this is configured so that it is executed from the initial address of the program at regular intervals, even if a runaway due to noise occurs, it will be reset after a predetermined time and it will return to the initial address of the program, so runaway due to noise Can be minimized. By the way, by writing a predetermined value at the final arrival address of the program and confirming the predetermined value at the initial address of the program, it is determined whether or not the program has normally performed processing up to the final arrival address. for that reason,
Since the above-mentioned fixed time (hereinafter, referred to as “reset interrupt time”) cannot be set too long,
The game program of the gaming machine is stored in a predetermined program size. Therefore, in order to generate a random number to be used for a game, a method of adding 1 for each reset interrupt and returning it to 0 at a maximum value in a predetermined range (hereinafter referred to as "+1 method") is used so that the program capacity may be small. Has been.
For example, in the case of a gaming machine belonging to the first type, if the probability of generating a special game is set to 1/210, 0-20
The above processing is performed within the range of 9. Based on the winning of the first type start opening that activates the special symbol variation device, the generated random number value is taken in, and at the time of determination, compared with a predetermined value (for example, "3") and the same case is hit, the special symbol variation device The winning symbol is stopped and the variable winning device is operated to perform a special game in which the player is provided with a profit. In the above +1 method, the reset interrupt time is 0.0
It is a very short time of 02048 seconds, and the cycle cycle is 0.43008 seconds (0.002048 × 210).
It is used as a random number because it is sufficiently short.

[0003]

Generally, a random number is a variable that does not have any rule in the method of value transition, and the original meaning is a sequence whose value cannot be predicted. However, the random number generated by the +1 method described above is used as a random number because the timing of capturing the value generated by the +1 method (at the time of winning the first-class starting mouth) is random and the one cycle is short. But +1
Since the value generated by the method is a regular arithmetic sequence obtained by adding 1, it cannot be strictly called a random number. That is, it is preferable that the random numbers that are the source of the randomness that determines whether or not to play the special game are statistically independent numbers. However, if the calculation is to generate statistically independent numbers, the program capacity will increase as compared with the +1 method, and as described above, it will be difficult to incorporate the program capacity into the determined program capacity.
Therefore, in the gaming machine control device, a game control device that performs game control and a random number generation device that generates random numbers used in the game are separated, and a mixed congruential method that generates uniform random numbers in the random number generation device, M series There is a method to use a statistically independent number without causing an increase in program capacity by performing random number generation processing such as the method, but the random number used for the game is provided outside the device that controls the game. If you contact them by bus or other means, it will be easier for a third party to tamper with them. The present invention has been made to solve the above problems, and an object of the present invention is to provide a gaming machine control device capable of generating high-quality random numbers and preventing falsification of the random number generation device.

[0004]

In order to solve the above problems, a gaming machine control device according to the present invention includes a game control device for performing game control, and a random number generation device for generating uniform random numbers used in a game. Is a game machine control device configured separately, and a read signal sending means for sending a read signal of a random number value to the random number generating device, and a random number value sent from the random number generating device by the read signal sending device. , A singular state determining means for determining whether the random number value captured by the random value capturing means is a singular state or a steady state, and a notification when the singular state determining means determines a singular state. Forced game ending means for playing and stopping the game, and fetched value validating means for validating the fetched value when the peculiar state judging means judges the normal state. Configured to include a. In the above, the singular state determination means may be in the singular state when the specific value is continuously acquired for each predetermined interval group. Further, in the above, the game control device comprises a random value fetch signal line monitoring means for monitoring a signal line fetching a random value from the random number generation device, and the random number value fetch signal line monitoring means keeps the signal line for a predetermined time. When the same value is held, the notification may be given and the game may be stopped. Alternatively, in the above, when the power is turned on, the game control device includes a random number generation device abnormality determination unit that controls the random number value acquisition unit and confirms a random number value sent from the random number generation device a predetermined number of times, and the random number generation The forced game ending means may be activated when it is determined by the device abnormality determining means that the device is in an abnormal state.

[0005]

According to the present invention having the above configuration, the random number value fetched from the random number generator is not used as it is in the game, but the correlation between the fetched value and the previously fetched value group is determined, and the intentional value is determined. It is determined whether or not there is such a thing, and since it is taken in as a random number value only when it is normal, it is possible to prevent tampering with a third party. Further, in the case of an abnormality, the player is notified and the game on the game machine is stopped, so unfair business cannot be performed due to falsification by a third party on the game machine. Further, the singular state determination means, when a specific value is continuously obtained for each predetermined interval group, by setting a singular state, for example, when a continuous random number is obtained within a predetermined time, When is a specific value (for example, jackpot value), it is determined to be a singular state, so
It is possible to prevent tampering by a third party, for example, an unjust game when a big hit value is continuously generated intentionally by the third party. Further, the game control device includes a random value fetch signal line monitoring means for monitoring a signal line fetching a random value from the random number generation device, and the random value fetch signal line monitoring means causes the signal line to have the same value for a predetermined time. By holding the notification and stopping the game when held, it is possible not only to prevent tampering by a third party, but also a defect due to a deficiency of the game machine control device (for example, between the game control device and the random number generation device). It is possible to prevent a case where a failure occurs in the information line (data bus or the like and is not intentional by the player), and it is possible to always provide the player with a normal game state. Further, the game control device includes a random number generation device abnormality determination unit that controls the random number value acquisition unit and confirms a random number value transmitted from the random number generation device a predetermined number of times when the power is turned on, and the random number generation device abnormality determination By activating the forced game ending means when it is determined to be in an abnormal state by means, it is possible not only to prevent tampering by a third party, but also to confirm whether the random number generator is operating or not. Since this can be done, it is possible to provide the player with a normal gaming state. Further, in this case, since the management device is also notified, the game machine control device can be replaced promptly.

Next, the outline of the game in the ball game machine of the present embodiment will be described with reference to FIGS. 1 to 3. Game section 3
When the gaming ball that has been discharged to and flows through the universal figure starting gate 8, it is detected by the universal figure starting switch 8S, and the universal figure starting detection signal is low-pass filter 20, buffer gate 21, bus (data bus and address bus) 22. Is sent to the CPU 10 via. The CPU 10 corresponds to the game machine control device and the game control device.

The CPU 10 outputs the above universal figure start detection signal to the R
It is stored in the AM 12 or the like, and based on this storage, the general-purpose memory display 9 via the bus 22, output port 27, and driver 26
The number of memories is displayed, and it is visually displayed that the player normally has the right to start the symbol display 7. Next, the CPU 10
Based on the above-mentioned universal figure starting memory, bus 22, output port 2
7. A control signal is sent to the normal symbol display 7 through the driver 26 to variably display numbers and the like.

Next, the CPU 10 takes out a random number (for example, "n") from the random number generation circuit 17 or the like, which is a random number generation device, after starting the above-mentioned universal figure variable display. The CPU 10 compares the fetched random number for stop symbol determination with a predetermined “hit” random number (for example, “7”), and if it matches, the hit control signal is the bus 22, the output port 27, It is sent to the starting opening solenoid 5L of the universal electric car 5 via the driver 26. When the hit control signal is issued, the starting opening solenoid 5
L is excited, and the state in which the ball is not accepted or difficult to accept is converted into a state in which the ball is easily accepted.

On the other hand, when the game ball that has flowed down wins the Poden 5, the first-class start switch 5S detects the winning ball, and the first-class start winning detection signal is sent to the low-pass filter 20,
The data is sent to the CPU 10 via the buffer gate 21 and the bus 22. Then, the hit ball that has won the prize 5 is processed as a prize ball, and when 7 prize balls are assigned to the prize 5, the CPU 10 sends the discharge ball to the discharge control device 37 that controls the discharge.
A seven-prize-ball data signal indicating that individual prize balls should be ejected is transferred, whereby seven balls are ejected as prize balls to a sphere supply tray (not shown).

Further, the CPU 10 stores the above-mentioned first type starting prize winning detection signal in the RAM 12 or the like, and based on this memory, displays it on the special symbol starting winning prize memory display portion via the bus 22, the output port 27 and the driver 26. A control signal is sent, and it is displayed on the special symbol start winning memory display section to visually display that the player has the right to start the special symbol display device 4. The maximum memory number of this special symbol starting memory is set to 4, for example.

Further, when the CPU 10 receives the first type start prize detection signal from the first type start switch 5S, it sends it to RA.
It is stored in M12 or the like. Then, the CPU 10 sends a display control signal to the special symbol display device 4 via the bus 22, the driver 26, and the output port 27 based on this storage, and the variable display game in which the numbers are variably displayed on the LCD or the like as the special symbol display device. To perform.

Then, the CPU 10 starts a random number from the random number generation circuit 17 or the like after starting the above-mentioned symbol variation game (for example,
"N") is taken out. The CPU 10 compares the extracted random number with a random number of “big hit” that is predetermined specific identification information (for example, “3” or the like), and if the numbers match, the big hit stop symbol (for example, “ "3,3,3" etc., etc.) is extracted from the jackpot stop symbol storage area,
After a predetermined time, while sending out to the special symbol display device and stopping it, the CPU 10 sends a big hit control signal to the special winning opening 6 via the bus 22, the output port 27, and the driver 26.

When the big hit control signal is issued, the big winning opening solenoid 6L in the big winning opening 6 is excited, and the first state in which the hitting ball is not accepted or the hitting ball is difficult to be received is converted into the second state in which the hitting ball is easily accepted. . This gives 1
The "special game" of the cycle starts.

At the same time, the CPU 10 causes the bus 22,
Decorative display 3 via output port 27 and driver 26
In addition to sending a display control signal to 0 to perform a visual display that excites the interest, a sound output control signal is sent to the speaker 25 via the bus 22, the sound generator 23, and the amplifier 24 to perform an acoustic output that excites the interest.

In the first cycle of the special game, when a game ball wins the special winning opening 6, one count switch 33 detects this winning ball, and the CPU 10 through the low-pass filter 20, the buffer gate 21 and the bus 22. Sends a winning detection signal to. Based on the winning detection signal, the CPU 10 counts the number of winning balls in the first special game cycle, and visually displays it on the winning number display unit or the like.

Then, the number of winnings to the special winning opening 6 in the first special game cycle reaches a predetermined number (for example, 10), or the special winning opening expanding timer (not shown) in the CPU 10 is set. When a predetermined time (for example, 29 seconds) has passed, the CPU 10 converts the special winning opening solenoid 6L into the first state. However, if the hit ball has won a continuous winning opening (not shown) in the special winning opening 6A during the second state conversion, the continuation switch 34 detects the winning ball to the continuous winning opening, and the low pass filter 20, A continuous winning signal is sent to the CPU 10 via the buffer gate 21 and the bus 22.

When the continuous winning signal is received, the CPU 10
Causes a continuation display section (not shown) to emit light to visually display to the player that the continuation condition is satisfied. First prize hole 6
When the continuation condition is satisfied after the lapse of a predetermined wait time after the conversion to the state, the CPU 10 again excites the special winning opening solenoid 6L to convert it to the second state. Further, the CPU 10 resets the count of the winning number display section to zero, stops the display of the continuous display section, updates the display of the cycle number display section, and the special game is in the second cycle. A display indicating that the user has entered, for example, "2" is visually displayed. If the continuation condition is not satisfied after a predetermined wait time has elapsed after the special winning opening 6 is converted to the first state, the CPU 10 ends the special game.

In this way, the special game cycle is renewed and the special game is continued by winning the hit ball at the continuous winning opening. When the number of updates of this cycle reaches a predetermined number (for example, 16 times), the final 16th
A predetermined number of prizes in the cycle (for example, 10)
When either condition is satisfied or a predetermined time (for example, 29 seconds) elapses, the CPU 1
0 ends the special game. When the special game is over,
The entire ball game machine returns to the normal game state.

As shown in FIG. 3, on the back side of the game board 1, a prize ball detection switch 35 for detecting a prize at each prize opening, and a game machine control device for controlling the operation of each part of the game machine. A discharge control device 37, a display control device 38, a firing control device 39 and the like are provided. Winning ball detection switch 35
Is a switch that detects a game ball that has generated a prize, and sends the prize ball number data to the discharge control device 37 based on the detection of this input. Further, data (special figure rotation signal, first-class start winning detection signal, jackpot control signal, etc.) and abnormal signal are sent to the management device 36, data (prize ball number data) is sent to the discharge control device 37, Data (display data (variable symbol data, stop symbol data, stored number display data, etc.)) is sent to the display control device 38, and a firing stop signal is sent to the firing control device 39. Further, the management device 36 stops the firing. An input signal such as an input signal from the winning ball detection switch 35 is received.

Next, FIG. 4 is a block diagram showing the functions of the gaming machine control device in this embodiment. As shown in the figure, the gaming machine control device includes a random number reading means as a reading signal sending means, a random number taking means as a random number value taking means, a unique state determining means as a unique state determining means, and a forced game ending means. It is provided with a forced game ending means and a random number storing means as a fetched value validating means. Further, it is provided with a signal line monitoring means as the random value fetching signal line monitoring means and an abnormality determining means as the random number generating device abnormality determining means. Each function of the above-mentioned gaming machine control device is realized by the CPU 10. The above random number generation device is realized by a logic circuit (IC) or the like.

Next, FIG. 5 is a block diagram showing the function of the random number generator according to the embodiment of the present invention. Random number read signal detection means for detecting a read signal of a random number value from the CPU 10 (role CPU) which is the game control device, and the role C.
Random number selection signal detecting means for detecting a selection signal from the PU,
Initial value storage means (in this case, the previous value is used in the non-volatile memory) for storing the initial value for performing the calculation, and multiplication means for extracting the initial value from the initial value storage means and multiplying by the specific value (for example, a = 1664525), addition means for adding the multiplied result with a specific value (for example, c = arbitrary odd number), rounding means for dividing the added result by a specific value to obtain a remainder (for example, M = 2 ³² ), and game Based on the initial value update signal detecting means for detecting the reset signal from the machine control device and storing the value obtained by the rounding means in the initial value storing means in order to set it as the initial value for the next calculation, and the random number selecting signal detecting means. The random number generation area selection means for selecting the range of values obtained by the rounding means, and the random number value selected by the random number generation area selection means based on the random number read signal detection means. The random number generation device is realized by the random number value sending means for sending to the CPU. The above means, the random number generation device generates a random number by a recurrence formula _{X n + 1 = aX n +} c (Mod M) using a pseudo-random number generating method "mixed congruential method".

For example, using the mixed congruential method described above, 20
Generate a random number of bits. Then, by the decode signal (2-bit data) from the outside, the generated 20 bits "0 to 7 bits", "4 to 11 bits", "8 to 15"
3 types of 8-bit data (0 to 255) of "bit", and 4-bit data (0 to 1 of 16 to 19 bit)
5) and a total of 4 types of random numbers can be selected. Then, the game control device (feature CPU) takes in this value, and the duty side determines. However, the captured random number value is 1 /
Since 256 or 1/16 probability values cannot be generated, if you want to generate a desired probability value (for example, 1/210),
A rounding process (for example, a process of weighting bits and rounding or a process of using a modulus function) is required on the accessory CPU side.

In the mixed congruential method, the initial value is used for the calculation, and thereafter, the calculated value is used as the initial value for the calculation. Therefore, in the random number generation device shown in FIG. 5, the timing of updating the calculated value as the initial value is synchronized with the reset interrupt peculiar to the gaming machine control. With such a configuration, the random number generation device also generates a random number by the reset interrupt, and is thus resistant to noise (can recover after a predetermined time even if it runs out of control). Further, since the initial value is constantly rewritten, there is an advantage that a uniform random number can be generated.

Next, FIG. 6 is a block diagram showing the function of the random number generation device according to another embodiment of the present invention. This random number generating device generates an initial value stored in the initial value storing means in the random number generating device of FIG. 5 in order to generate a random number of higher quality (more randomness) than the random number generating device of FIG. An initial value generating means for generating is provided, and thermal noise (thermal random noise) is spatial noise instead of using a previous value by using a non-volatile memory like the random number generator of FIG. Yes Take advantage of high randomness,
This is used as an initial value for random number generation. The random number generated in this way has spatial randomness because it uses spatial noise rather than the random value stored as the initial value, and it becomes an initial value with higher randomness, and it is determined between gaming machines. There is an advantage that the random number used as the value is a random random number without phase shift.

Next, FIG. 7 shows an example of a concrete configuration example of the initial value generating means in FIG. The AC component of the resistance value 41 is extracted by the capacitor 42 (acquiring thermal noise due to heat generation of the resistor, thermal noise generating means), amplified by the amplifier 43 (amplifying means), and the amplified noise is A / D converter 44. 8 bit conversion (A / D conversion means), and the value is extracted at random time (sampling means) as an initial value.

Next, FIG. 8 shows another example of a concrete configuration example of the initial value generating means in FIG. This is another embodiment of a circuit that generates a spatially random number. In this way, a more random number is generated and used as the display symbol on the special symbol display device when the power of the game machine is turned on. As the method, for example, the A / D converted value is extracted at random time and used as the symbol data for display.
More specifically, 4 bit conversion and random time extraction,
This is done for the corresponding symbol, and is used as display symbol data of the special symbol display device.

With this configuration, when a special symbol is displayed on the special symbol display device when the power is turned on, the player
Looking at the design, judging that the game is not being played on that day, avoiding the game on that machine, and causing a bias in the usage rate of the game machines in the game store, etc. There is an advantage that the inconvenience of is solved. in this case,
Programmatically, it is difficult to make the initial pattern random when the power is turned on, but spatial noise (thermal noise) is difficult.
Since the use of, it is possible to easily change the initial design when the power is turned on, and even the same model can be made different.

Next, the operation of the ball game machine of this embodiment is shown in FIG.
8 to 9 and the flowcharts of FIGS. 9 to 19 will be described below.

The CPU 10 (FIG. 2) of this ball game machine is
As shown in the general flowchart in Fig. 9, the steps from "Start" to "Waiting for reset" are cycled for 2 msec.
Are sequentially repeated by the reset signal. In "waiting for reset", the operation is stopped until the next reset signal is received.

Next, when the power is turned on in step S1, initialization processing (step S15) is executed.
This initializes the memory and the register, and creates the initial symbol data to be displayed on the special symbol display device 4.
This initial symbol data is sent to the display control device 38 (FIG. 3) and displayed in the data transfer process.

When the power is not turned on in step S1, it is determined whether or not the process is changed to the game stop process (step S16) (step S2). If Y, the process is shifted to the game stop process (step S16). . In the case of N in step S2, it is determined whether or not the random number generator life confirmation process (step S17) at power-on is performed (step S3), and in the case of Y, the random number generator life confirmation process (step S17) is performed. In the case of N, the process proceeds through the prize ball control process (step S4) for sending the prize ball number data to the discharge control device 37, the SW input process (step S5)
(Step S6), a normal process (Step S7), a symbol variation process (Step S)
8), the big hit process (step S9), the out-of-range process (step S10), and then external information processing (step S)
11), data transfer processing (step S12), output processing (step S13), signal line monitoring processing (step S1)
After 4), "waiting for reset" is reached.

In the above initialization processing (step S15), as shown in FIG. 10, first, the memory, the register, etc. are initialized in the initialization (step S21).
The following process is performed as a process of creating a display symbol for initial display when the power is turned on to the special symbol display device 4. That is, a spatially random numerical value A / D converted by the circuit shown in FIG. 8 is subjected to sampling processing for sampling at random time (step S22), and the symbol corresponding to the sampled value is determined (step S23). . For example, A / D conversion is performed by 4 bits and sampling is performed for 3 symbols. Then, hexadecimal (4 bits) data is set as display symbol data (step S2).
4). This data is processed by the data transfer process (step S1).
In 2), it is transferred to the display control device 38 (FIG. 3), and the corresponding symbol is displayed on the special symbol display device 4.

In the above game stop processing (step S16), as shown in FIG. 14, first, OFF data is set to all output data (step S61) to deactivate the output parts, and the game area 3 is played. A firing stop signal for stopping firing is set to the firing control device 39 so that the ball cannot be ejected (step S62).

Next, it is judged whether or not the routine is called by the random number generator life confirmation process (step S6).
3), in the case of Y, the abnormal signal is set to send the abnormal signal to the management device (step S66), and in order to make it possible to identify that an abnormality has occurred in the random number generator life confirmation process, the lamp A process of blinking the LED is performed (step S67).

If N in step S63, it is judged whether or not it is the signal line monitoring process that called this routine (step S64).
In order to make it possible to identify that an abnormality has occurred in the signal line monitoring process, a process of blinking the lamp is performed (step S65). Then, in the case of N in step S64, a process of blinking the lamp is performed to indicate that the random number generation device may be tampered with (step S6).
8).

In the above-mentioned random number generator life confirmation process (step S17), as shown in FIG. 11, first, in order to confirm the life of the random number generator at power-on, first, a random number fetch process (step S31). ) Is performed, and a random number value is taken in to perform the determination in the unique state determination process (step S32). Then, this check is performed, for example, 1000 times (for 2 seconds by interruption of 2 msec) (step S3
3) If there is no abnormality, the life-and-death confirmation process of the random number generation device is canceled to perform the normal process (step S34).

The random number fetching process (step S3)
In 1), as shown in FIG. 12, first, a selection signal is sent in order to fetch a random number value into the random number generator (step S41). This signal serves as a decode signal indicating which range of the random number generated by the random number generation device is fetched. Then, a read signal is transmitted (step S42), and the system shifts to a random number value capturing system to capture the random number value (step S42).
43), return to the called routine.

In the singular state determination process (step S32), first, as shown in FIG.
It is determined whether or not the block serving as the criterion for the determination (one block by continuously obtaining the random number value four times) is completed (step S51). As a result, in the case of N, the determination within the block has not been completed yet, so the determination within the block is continued. First, it is determined whether or not the current captured random number value and the previous captured random number value are the same (step S52), and if they are the same, 1 is added to the block storage area (step S53). Then, it is determined whether the storage value of the block storage area is 4 (step S54). That is, it is determined whether or not the same value is obtained four times in a row, and if the same value is taken in four times in a row, the processing is changed to the game stop processing to stop the game (step S55), Return to the called routine.

When the determination in the block is completed in step S51, it is determined whether or not there is a block memory, that is, whether or not the same value continuously appears in the block (step S56). In this case, 1 is added to the block group storage area (step S5
7), in the case of N, the storage of the block group storage area is cleared (step S60). Then, the stored value in the block storage area is cleared (step S58), and it is determined whether the block group storage is 6 (step S59). That is, it is determined whether 6 consecutive blocks in which the same value occurs consecutively in the block, and 6 consecutive blocks occur.
If a block occurs, the process is changed to the game stop process to stop the game (step S55), and the process returns to the called routine. For example, as described above, instead of using the same consecutive values in the block as the determination material, the case where the same value occurs in the block may be used as the determination material.

Then, the SW input process (step S
As shown in FIG. 16, 5) detects winning of the Poden 5 (first type starting switch 5S), fetches a random number value from the random number generation device, and determines whether or not the fetched random number value is a peculiar state. If it is normal, it is stored in a predetermined storage area. First, it is determined whether or not there is a winning at the starting opening (step S8).
1) If the winning is recognized, it is judged whether or not the current starting mouth memory is four or more (step S82), and if less than four, 1 is added to the starting memory (step S83), and the random number is collected. The random number value is fetched by calling the import process (FIG. 12) (step S84), and the singular state determination process (step S85) is performed to determine whether the imported random number value is normal.
I do. As a result, in the case of a normal value, a rounding process (for example, using the remainder obtained by dividing the fetched value by 210) is performed so that the fetched random number has a predetermined range (for example, 1/210) ( In step S86, the random number determination area is stored (step S87) and the process returns.

In the singular state determination process (step S85), as shown in FIG. 17, first, a block serving as a reference for determination (random number value is obtained four times in succession is set to 1).
It is determined whether or not the block has ended (step S
91). As a result, in the case of N, the determination within the block has not been completed yet, so the determination within the block is continued. Then, it is determined whether or not the captured random number value this time is the same as the jackpot determination value (step S92), and if the same is the same, 1 is added to the block storage area (step S93). Then, it is determined whether the storage value of the block storage area is 4 (step S94). That is, it is determined whether or not the jackpot value is obtained four times in a row, and when the jackpot value is taken in four consecutive times, the processing is changed to the game stop processing to stop the game (step S95), and the call is made. Return to the routine.

When the determination in the block is completed in the above step S91, it is determined whether or not there is a block memory, that is, whether or not the jackpot value continuously appears in the block (step S96), and Y In the case of, 1 is added to the block group storage area (step S
97), in the case of N, the storage of the block group storage area is cleared (step S100). Then, the stored value in the block storage area is cleared (step S98), and it is determined whether the block group storage is 6 (step S99). That is, it is determined whether or not 6 blocks in which a jackpot value has occurred are continuously generated, and 6 blocks are consecutively generated.
When the block occurs, the process is changed to the game stop process to stop the game (step S95), and the process returns to the called routine.

When the SW input process is completed, "normal process (step S7)" and "symbol change process (step S6)" are executed by "branch by process No. (step S6)".
8) "," big hit process (step S9) ", and" out-of-range process (step S10) ".

Next, in the above-mentioned normal processing (step S7), as shown in FIG. 18, it is first judged whether or not there is a starting memory (step S101). Subtracting (step S102), obtaining the corresponding random number value from the random number determination storage area (step S103), comparing the obtained random number value with the set random number determination value (step S104), and the result (step S104).
105) If the hit is a big hit stop symbol, if it is lost, the missed stop symbol is extracted from the symbol storage area and determined as a stop symbol (steps S106, 10).
8). Then, the process is changed to the symbol variation process (step S107), and the process returns to the main routine.

Then, the above-mentioned symbol variation process (step S
In 8), as shown in FIG. 19, first, it is determined whether it is the fluctuation stop timing of the special symbol display device (step S111). This is to determine whether it is the stop timing of the final stop symbol. As a result, in the case of N, it is determined whether or not it is the first half of the fluctuation of the special figure (step S1
16), in the case of Y, high-speed fluctuation processing is performed (step S11).
7), in the case of N, low speed fluctuation processing is performed (step S1).
18). This is to change the fluctuation at high speed in the initial stage when the special map changes and to switch the fluctuation at low speed after a predetermined time.

Then, it is determined whether or not the symbols other than the final stop symbol are stopped by the same symbol in the low speed variation process (whether it is reach) (step S119), and if it is the same symbol, the reach variation process is performed (step S120). Here, the reach variation process is a process in which the appearance of the final stop symbol is performed more decoratively.

Further, in the case of the variable stop timing in the step S111, the final stop symbol is stopped (step S112), and whether the symbol is a jackpot symbol,
That is, it is determined whether all the symbols are available (step S113). In the case of a big hit, the process is changed to a big hit process (step S114). In the case of a loss, the process is changed to the disconnection process (step S11).
5).

Further, the big hit process described above (step S9)
Is a process of opening the special winning opening 6 and giving a game value to the player. In this process, first, the V winning (continuation switch winning) and the winning of the count switch are checked to determine whether the condition for ending one cycle is satisfied, that is, whether the condition for closing the special winning opening 6 is satisfied. . Then, when the condition is satisfied, it is determined whether or not the continuation condition is satisfied, that is, whether or not the continuation switch is won. If it continues, it shifts to the big hit process in the next cycle and continues up to 16 times.

Further, the above-mentioned disengagement process (step S10)
In, it is a process when the special symbol is removed. When the above process is completed, external information processing (step S11. For example, a process of transmitting a rotation signal of a special figure, a winning signal to the starting opening, a jackpot signal, etc. to the management device,
Also, a process of sending an abnormal signal to the management device, a process of sending a firing stop signal to the firing control device, and the like. ), Data transfer processing (step S12. Special symbol display device 4 (LC
Processing to transfer display data to D etc.). ), Output processing (step S13. Processing for outputting lamps, LEDs, solenoids, etc.), and signal line monitoring processing (step S14), and then waits for resetting.

Further, the above-mentioned signal line monitoring processing (step S
The process 14) is a process of monitoring the data bus in communication with the random number generation device to check whether there is any abnormality or whether the data bus has been tampered with (eg, not processed). First, the data of the data bus (8 bits = 8 lines) is read (step S71), and if there is a transition data among the respective data, the storage of the corresponding data storage area is cleared (step S72) and the transition is made. If there is no data, 1 is added and stored in the corresponding data storage area (S73). The storage value of each data storage area is 10
It is judged whether or not there is one that has become 00 (step S7
4) If the stored value is not 1000, return as it is, and if the stored value is 1000, change the process to the game stop process to stop the game operation (step S75), and return To do. That is, eight data lines are constantly monitored, and it is determined as abnormal when there is no data transition on the data lines for 2 seconds (1000 in the case of a reset interval of 2 msec). This stored value is 10
Any value other than 00 can be set.

As described above, according to the present invention having the above-mentioned configuration, the random number value fetched from the random number generator is not used for the game as it is, but the fetched value and the previously fetched value group are used. It is possible to prevent tampering with a third party because the correlation is determined, whether there is an intentional one is determined, and the random number is taken in only in the normal case. Further, in the case of an abnormality, the player is notified and the game on the game machine is stopped, so unfair business cannot be performed due to falsification by a third party on the game machine. Further, the singular state determination means, when a specific value is continuously obtained for each predetermined interval group, by setting a singular state, for example, when a continuous random number is obtained within a predetermined time, When is a specific value (eg, big hit value), it is determined to be a peculiar state, so it is tampered with by a third party, for example, an illegal game when the big hit value is continuously generated intentionally by a third party. Can be prevented. Further, the game control device includes a random value fetch signal line monitoring means for monitoring a signal line fetching a random value from the random number generation device, and the random value fetch signal line monitoring means causes the signal line to have the same value for a predetermined time. By holding the notification and stopping the game when held, it is possible not only to prevent tampering by a third party, but also a defect due to a deficiency of the game machine control device (for example, between the game control device and the random number generation device). It is possible to prevent a case where a failure occurs in the information line (data bus or the like and is not intentional by the player), and it is possible to always provide the player with a normal game state. Further, the game control device includes a random number generation device abnormality determination unit that controls the random number value acquisition unit and confirms a random number value transmitted from the random number generation device a predetermined number of times when the power is turned on, and the random number generation device abnormality determination By activating the forced game ending means when it is determined to be in an abnormal state by means, it is possible not only to prevent tampering by a third party, but also to confirm whether the random number generator is operating or not. Since this can be done, it is possible to provide the player with a normal gaming state. Further, in this case, since the management device is also notified, there is an advantage that the game machine control device can be promptly replaced.
