DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game control device for controlling a game machine such as a pachinko game machine, and more particularly, to preventing a game from being illegally played by a player and providing a sound game. A game control device.

[0002]

2. Description of the Related Art Conventionally, in a gaming machine such as a pachinko gaming machine, amusement of a game is enhanced by a variable display game on a special symbol display device arranged substantially at the center of a gaming area.

[0003] Generally, in this variable display game, when a predetermined game condition such as a prize in the first kind opening is established, a symbol displayed on a special symbol display device is started to be changed and displayed. When a predetermined time elapses from the start, the variable display is stopped, and when the symbols at the time of the stop are arranged in special symbols, a special game for giving a profit or a privilege to the player (ie, giving a game value) as a jackpot. Is a game that causes the game to be performed.

In such a variable display game, a stochastic element is included in the determination of the jackpot or the symbol at the time of stop, and the interest in the game is excitement by accompanying the chance.

By the way, in an environment in which a game control device for controlling the game of a pachinko game machine is installed, metal game balls are constantly circulating, and noise generated by the circulation of the game balls is always present. In the state of being. Then, C that functions as an arithmetic processing device mounted on the game control device
The PU runs the risk of runaway due to this noise.

Therefore, as a countermeasure against runaway of the CPU, a reset interrupt process is executed for the CPU at certain intervals.
(The CPU is reset by an external circuit of the arithmetic processing device, or in a game arithmetic processing device having a built-in CPU, ROM, RAM, etc., the CPU is set by software.
There is a processing mode in which the program is executed every time from a predetermined address (for example, an initial address) of the program. As a result, even when a runaway due to noise occurs, the CPU is reset after a predetermined time and returns to the predetermined address of the program, so that the adverse effect of the noise can be minimized.

In order to execute a program by executing a reset interrupt to the CPU every certain time as described above, the reset interrupt time cannot be set too long for the purpose. The game program of the pachinko gaming machine is stored in a predetermined program size so that processing can be executed within a predetermined time.

The random numbers used for determining the jackpot (determination of the game value), the symbols at the time of stopping, and the like are as follows:
Although it is preferable to use a random number with truly irregularity, it is required that the program that generates this random number be as small as possible, and at present it is necessary to use a simple random number generation method. is there.

That is, as a simple random number generation method requiring only a small program size, a so-called carry counter method is used in which 1 is added to a random number variable every time a reset interrupt is performed, and the variable is returned to 0 when a predetermined value is exceeded. Is widely used (commonly known as +1 method).

For example, in the case of a pachinko game machine in which the jackpot probability in the variable display game is set to 1/210, the count value in the range of 0 to 209 is changed by +1 at every reset interrupt. . Then, based on the winning in the first type starting port which is a trigger for starting the variable display game, the count value at the time of winning is captured as a variable for random number, and when the big hit is determined in the variable display game, the captured random number is used. The variable (count value) is compared with a predetermined judgment value (for example, "3"), and when both are the same, a big hit is determined, and the symbol displayed variably on the special symbol display device is stopped according to the big hit symbol. At the same time, the variable winning device is opened to allow the player to play a special game.

In this random number generation method of the carry counter method, the interval at which the reset interrupt is performed is 0.00204.
8 seconds (about 2 msec), and the cycle in which the above-described count value makes one cycle is 0.43008 seconds (0.002048 × 2).
10) is extremely short, and since the timing of taking in the random numbers is when the game ball rolling on the game board surface enters the first kind starting port, randomness can be secured.
It is used as a random number in a variable display game or the like as it sufficiently satisfies the condition as a random number.

[0012]

However, in such a conventional gaming machine, a program is executed by executing a reset interrupt to the CPU every certain time. Since the random number generation counts up (+1) at regular intervals, the random number update has periodicity.

In recent years, pachinko games have become widespread in the public as familiar and popular entertainment, and along with this, there have been a variety of magazines and other publications on which new information on pachinko machines and information such as game contents have been published. Sold.

In such magazines and the like, an analysis article of a pachinko game machine and the like inside the pachinko game machine, which was previously known only to the game machine maker, is also published as a part of the provided information. A strategy focusing on the random number updating method of the machine is also described. One of the strategies is a method of inducing a big hit using a device called a bodily sensation device.

The bodily sensation device uses a certain periodicity defined by the above-described cycle of the count value and the like, and uses a rhythm such as vibration every predetermined time (an integer multiple of the cycle time of the game machine's count value). A game method using a bodily sensation includes the following "methods that violate the soundness of the game" and "methods that result in illegal games".

"What violates the soundness of the game" This is achieved by operating the firing handle and the stop switch of the firing operating section using the vibration generated by the bodily sensation (vibration indicating the above-mentioned fixed period). In addition, a prize is awarded to the first-class starting port at a timing generated by the above-mentioned body sensation,
While shifting the timing generated by the bodily sensation, the big hit value is subtracted by itself, and the timing is fixed to the bodily sensation. Thereafter, the vibration cycle generated by the body sensation is synchronized with the jackpot value in the circulating count value, and if the first-class starting port is won at this timing, the game being executed is performed. The program extracts the jackpot value from the circulated count value, and the jackpot game is executed.

Such artificial jackpot occurrence is not different from a normal game operation except for the use of a bodily sensation (although it is different from a normal firing operation because a single hit is performed), A remarkable difference in profits occurs between the player who does not use the game and the profit, which is contrary to the purpose of the sound game (the game machine is created on the assumption that the normal firing operation is performed).

"Illegal game" This also uses a bodily sensation device as described above. In this case, a skilled firing operation is used to win a prize at a timing when a big hit value is subtracted from the first type starting port. Instead, the electromagnetic wave is radiated at the timing described above, and a signal is forcibly input to a sensor (for example, a proximity sensor) in the first type start port regardless of winning of the game ball.

This is, of course, not a normal game but an unjust act. In addition, the appearance has a disadvantage that it is harder to find than the above-described artificial firing operation. (The artificial firing operation can be confirmed by a clerk, but when using electromagnetic waves, This is an act of irradiating electromagnetic waves at the timing of the bodily sensation while firing, which makes it difficult for the clerk to confirm).

Further, as described above, in the case of fraud by electromagnetic wave irradiation, only the "body sensation" is used together with the "body sensation" in order to improve the efficiency. Unauthorized games in which a sensor in a seed starting port is input are also performed.

In recent years, not only the illegal game method using the bodily sensation device but also a person who attaches an illegal device, commonly called a “hanging substrate”, to the game machine and plays an illegal game.

This is because a "hanging board" is interposed between a start sensor for detecting a winning ball provided in the first kind start port and the game control device, and a reset interrupt output from the game control device to an external device. By taking in a signal that can be synchronized with the "hanging board", the timing of updating the count value created by the game program executed by the arithmetic processing device provided in the game control device is synchronized with the count value, Understand the timing of updating to the jackpot value, and determine the timing of winning the game ball to the first type starting port,
A timing winning signal at which the count value is updated to the jackpot value is output to the game control device, so that the jackpot value can be obtained by winning the game ball. In other words, the timing is adjusted and output to the game control device side so that the winning of the game ball to the first type starting port can be obtained with the "hanging substrate" and the jackpot value on the game control device side.

In this case, the game machine is stolen during the distribution process and the game program stored in the ROM is analyzed.
Recognizing the random number cycle (big hit probability), the big hit determination value, etc., that is, creating a “hanging board” suitable for the model.As a result, by performing the above-described method, the “hanging board” is transmitted to the game control device. On the other hand, a signal taken from the starting sensor can be output at the timing of extracting the jackpot value.

The "hanging board" is installed during the operation of the game store, sneaked into the game store at night, or mounted in the course of distribution of the game machine.

In the various ways described above, illegal or unfair game methods that are against the purpose of sound game play are performed, and cause great inconvenience to sound players and game stores. As a result, it has become a problem for the pachinko machine industry as a whole, including game machine manufacturers.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a gaming machine capable of preventing a player from unjustly playing a game and playing a sound game.

[0027]

According to a first aspect of the present invention, the progress of a series of game programs is set within a predetermined interruption time, and the game program is determined in advance for each predetermined interruption signal. A game control unit that performs game control by executing the game control from a predetermined address, the game control unit adds a predetermined value to a previous value based on an interrupt signal, and sets a predetermined period. When it reaches the initial value, random number generation means for generating a random number used for the game by correcting to the initial value, and after a series of game programs based on the interrupt signal progress, until the next interrupt signal input In the remaining time,
A predetermined value is added to the previous value, and when a predetermined period is reached, the correction value is corrected to an initial value, thereby generating a correction value that causes a regularity of the random number generated by the random number generation unit. Correction value generation means, the random number generation means includes a random number diffusion means for changing a predetermined value to be added to the previous value based on the correction value of the correction value generation means, the random number diffusion means When the random number generated by the random number generation unit becomes an initial value, a correction value is reacquired from the correction value generation unit.

In a second aspect based on the first aspect, the game program includes a time-division process.

The game processing, normal symbol game processing, symbol change processing, decoration editing processing, solenoid editing processing, fraud monitoring processing, display control device transmission command processing, and external information processing processing are performed every time the CPU is reset (a) S1 → S2 → S3 → S4 → S12 → S13 → S14 → S22 (b) S1 → S2 → S3 → S5 → S12 → S13 → S15 → S22 (c) S1 → S2 → S3 → S6 → S12 → S13 → S16 → S22 (d ) S1 → S2 → S3 → S7 → S12 → S13 → S17 → S22 (e) S1 → S2 → S3 → S8 → S12 → S13 → S18 → S22 (F) S1 → S2 → S3 → S9 → S12 → S13 → S19 → S22 (g) S1 → S2 → S3 → S10 → S12 → S13 → S20 → S22 (h) S1 → S2 → S3 → S11 → S12 → S13 → S21 → S22 (a) → (b) → (c) → (d) → (e) → (f) →
Time division (8 divisions) processing is performed in the order of (g) → (h). If the reset interrupt time is, for example, 2 msec, S4 to S4
The processing of 11 and the processing of S14 to S21 are each performed once every 16 msec (2 msec × 8).

The processing times of S1 to S22 in (a) to (g) are set so that the processing ends within the reset interruption time.

In the power-on determination processing in S1, initialization processing such as initialization of the RAM is performed only when the power is turned on, and the processing is skipped after the power-on.

In the input processing of S2, chattering removal and logical conversion of the input signal of each switch are performed.

In the random number generation process of S12, a random number for a jackpot of an image game, a random number for a general symbol, and the like are generated, and a stop symbol (a combination of a plurality of symbols) for the image game is created. In the case of a combination of big hit symbols, the stopped symbol is stored in a big hit stopped symbol storage area, and in the case of a combination of lost symbols, the stopped symbol is stored in a lost stop symbol storage area. Generation of the random number for the jackpot will be described later.

In the switch winning process in S13, when a winning is found in the starting port 7 based on the input signal processed in S2, the winning is stored as a special figure start memory (up to four), and For each winning, a jackpot random number generated in the random number generation process of S12 is extracted and stored. If there is an input from the safe sensor 37, it is determined whether or not there is a prize memory of the starting port 7. If there is a memory, 7 prize balls are stored. If there is no memory, 13 prize balls are stored. Further, based on the input of the general-purpose start gate switch 31, a general-purpose start memory,
It performs a process of acquiring a random number for ordinary drawing, a winning process of the count switch 32 and the continuation switch 33 in the variable winning device 5 at the time of a big hit, and the like.

The special symbol game process in S14 is divided into a normal process and a jackpot process. In the normal process, when there is a winning memory of the starting port 7 (special figure starting memory), the random number value extracted and stored with the winning is read and determined. Then, the stop symbol of the image game is determined. In the jackpot process, based on the result of the normal process, the opening and closing of the variable winning device 5 and the setting of the display information at the time of the jackpot to the display control device 34 are performed in the case of the jackpot.

In the normal symbol game process of S15, when there is an input (general symbol start memory) of the general symbol start gate switch 31,
The variable display of the general-purpose indicator 10 is performed, and the stop of the variable display is instructed by a number or the like corresponding to the obtained random number for the general-purpose figure, and the electric tulip 6 of the starting port 7 is opened in case of a hit. Perform the following processing.

The symbol change process of S16 is performed by the display control device 3
4 sets symbol information for performing variable display of symbols on the image display device 4. By transmitting display position data for displaying the symbol, the rotation of the symbol is managed.

The decoration editing process in S17 is performed by using a lamp / LED
And other control data. In the solenoid editing process in S18, solenoid data is set based on the data set in the special symbol game process in S14 and the normal symbol game process in S15.

The fraud monitoring process of S19 is performed by the variable prize device 5
When the device is opened, monitoring of illegal no-count is performed based on the input of the count switch 32 and the like.

The display control device transmission command process of S20 is based on the data set in the special symbol game process of S14 and the symbol variation process of S16, and is executed by the display control device 34.
Edit the display information to send to.

The external information processing in S21 includes a jackpot signal,
In order to notify the certainty change signal, the symbol stop signal of the image game, and the like to the outside (management device), the data of the corresponding event is edited.

The remaining time processing of S22 is for spreading the regularity (including periodicity) of updating the random number for jackpot, and when the processing of S14, S15, S16,. , The counter P of a predetermined cycle is kept rotating until the next reset interrupt is applied to the CPU. In this case, as shown in FIG. 4, it is determined whether or not the value of the counter P is 5 in S31. If it is not 5, +1 is added in S33 and stored in the counter P, and the process returns to S31.
Stores 1 in the counter P and returns to S31.

That is, the value of the counter P is 1 → 2 → 3 → 4 →
5 → 1 → 2 → 3 → 4 → 5..., And updates are updated by a series of programs (S1 → S2 → S3 → S4 → S12 → S
13 → S14 or S1 → S2 → S3 → S5 → S12 →
S13 → S15 or S1 → S2 → S3 → S6 → S12
→ S13 → S16… or S1 → S2 → S3 → S11 →
After the end of (S12 → S13 → S21), the remaining time until the next reset interrupt is applied continues. Since the remaining time differs depending on the progress time of each series of programs, the value of the counter P at the end of the remaining time processing is 1, 2, 3, 4,
5 is a random value.

As shown in FIG. 5, the random number generation process for jackpot in S12 obtains the previous random number value stored in the random number storage area in S41 and sets the previous random number value to 0 in S42.
It is determined whether or not.

If the previous random number value is 0, the process goes to S43 at S2.
Data corresponding to the value of the counter P created in the remaining time process 2 is set to Q (addition value of random number), and the process proceeds to S44. If the previous random number value is not 0, the process proceeds to S44.
Move to.

In S44, Q is added to the previous random number value and stored in the random number storage area as a new random number value.

In S45, it is determined whether or not the new random number (previous random number + Q) is equal to or larger than the set value A. If it is smaller than the set value A, the process returns from the process.

On the other hand, a new random number value (previous random number value + Q)
Is greater than or equal to the set value A, the correction process is performed in S46, and the value corrected in the correction process is stored in the random number storage area again as a new random value in S47.

In the jackpot random number generation processing, when the random number value for jackpot becomes 0, the value of the counter P in the remaining time processing in S22 is obtained, and the added value Q of the random number corresponding to the value of the counter P is obtained. Is updated, and the update is performed by adding the added value Q of the random number to the previous random number value and adding the added value Q at a time. When the updated random number value (previous random number value + Q) is equal to or larger than the set value A, the correction process of S46 determines the set value A
Is subtracted and corrected.

In this case, for example, when a random number with a probability of 1/211 is set, the random number value is 0, 1, 2,... Also, the addition value Q of the random number
Is set according to the value of the counter P, for example, as shown in FIG. However, the added value Q of the random number is a prime number that is not a divisor of the set value A.

That is, the counter P in the remaining time processing of S22 acquired when the random number value for jackpot becomes zero.
Is set in accordance with the value of the random number, and the random number for the jackpot is updated by the added value Q. At this time, when the random number for the jackpot becomes equal to or more than the set value A, the random number for the jackpot Is subtracted from the set value A, and this operation is performed until the random number value for the jackpot completes one cycle (until the random number value for the jackpot becomes 0), and these operations are repeated.

More specifically, for example, when a random number having a probability of 1/211 and the added value Q of the random number set in correspondence with the obtained value of the counter P is 3, as shown in FIG. .., 204, 207, 2
If it is updated to 10 and added as it is, then it becomes 213, which is equal to or larger than the set value.
13 is subtracted from the set value 211 to obtain 213−211 =
2 is set as a new random number value, and the random number value 2 is added and updated by 3 in the same manner. Then ... 203, 2
06, 209 and then 212, the set value 211 is subtracted from that 212,
211 = 1 is set as a new random number value, and the random number value 1 is similarly updated by adding 3 each. And ... 2
It is updated to 02, 205, and 208, and when it becomes 211 next, it becomes 211-211 = 0, returns to the initial value, and makes one cycle. As described above, the random number value for the jackpot goes around while updating the added value Q, and when the round has been completed, a new added value Q corresponding to a new value of the counter P is set, and the above processing is repeated.

Therefore, the cycle of the random number for the jackpot changes, and the regularity of updating the random number for the jackpot is diffused. In addition, the order of updating the jackpot random numbers changes each time the circuit goes round, so that the regularity of updating the jackpot random numbers is further diffused.

The big hit random number generation processing is established when the added value Q of the random numbers is a prime number that is not a divisor of the set value A, or when the set value A is a prime number. When the added value Q is X, the cycle of the random number for the jackpot is X times that when the added value Q is 1.

With such a configuration, when a game is played and a game ball wins in the starting port 7, a random number for a jackpot is extracted at the time of winning, and a plurality of symbols on the image display device 4 are variably displayed. . If the extracted jackpot random number is a jackpot value, the variable display of a plurality of symbols is stopped in a predetermined combination after a predetermined time has elapsed, a jackpot is generated, and the variable winning device 5 is opened for a predetermined period. A game is played.

In this case, if there is a periodicity (regularity) in the update of the random number for jackpot, based on the regularity, the updating of the random number using the bodily sensation device or the like is performed as described above. There is a concern that a jackpot may be illegally generated by attaching an unauthorized device such as the one described above, but such an unreasonable and illegal occurrence of the jackpot is prevented by the present embodiment.

The random number for the jackpot according to this embodiment is
Reset interrupt and a series of programs (S1 → S2
→ S3 → S4 → S12 → S13 → S14 or S1 → S
2 → S3 → S5 → S12 → S13 → S15 or S1 →
S2 → S3 → S6 → S12 → S13 → S16 ... or S
After the completion of (1 → S2 → S3 → S11 → S12 → S13 → S21), the update is performed based on the value of the counter P which continues to rotate for the remaining time until the next reset interrupt is applied.

The value of the counter P is, for example, S4 to S1
1. Since the processing times of S14 to S21 are different (the through processing is the same), for each series of time-division processing programs,
The remaining time until the next reset interruption after the end is different, and by turning the counter P to this remaining time, the value becomes an arbitrary value (for example, any one of 1 to 5).

In the same process, if there is a winning in the starting port 7, for example, a process of extracting and storing the random number value generated in the random number generation process of S12 as in the switch winning process of S13, If there is no winning, this processing is not performed, so that a difference in processing time appears here. That is, also in this case, the remaining time is different, and the value of the counter P changes.

Therefore, each time the jackpot random number becomes an initial value, an addition value Q (for example, FIG. 6) of the random number is set in accordance with the value of the counter P at that time, and the jackpot is determined according to the addition value Q. Since the addition random number is updated, that is, the addition value for updating the jackpot random number is set randomly each time the jackpot random number makes a round, the cycle of the round of the jackpot random number changes (for example, when the addition value Q is 3). The cycle of the random number for the jackpot at the time of (3) is three times as large as when the addition value Q is 1.) Also, the order of updating the jackpot random numbers changes. As a result, the jackpot random number is randomly updated in response to a reset interrupt from the CPU, and the regularity of the update is diffused.

Therefore, even if a bodily sensation device or the like that generates vibrations of a fixed period is used, it is impossible to generate a big hit because the update of the random number for the big hit has no regularity.
Further, even if an input signal of the starting port 7 is generated by irradiating the electromagnetic wave, or a big hit is generated by using a body sensation together with the irradiation of the electromagnetic wave, the random number is not regularly updated. Is difficult. Further, even if an illegal device such as a hanging board is attached to a game machine and an illegal game is played, a big hit cannot be generated because the random number for the big hit is not updated regularly. In particular, even if the game program stored in the ROM is analyzed, it is difficult to create a hanging board or the like because the random number update cycle for the jackpot cannot be grasped.

In this way, the occurrence of a jackpot is prevented from being unfair and unjustified. On the other hand, after the end of a series of programs, the remaining time counter P until the next reset interrupt is started is turned on. Since the value of P is used for updating the random number for the jackpot, a random number generation program is easily created.

That is, the random number generation program is complicated because the addition value Q of the random number is set based on the value of the counter P, and the random number for the jackpot is generated while following the counter method of updating the value by a predetermined value. No program size. Also, even in the simple counter-type random number generation process, the regularity of the update is accurately mixed.

Therefore, high reliability of the game control and the game machine can be obtained.

As described above, there is a difference in the processing time of the switch winning process in S13, for example, between the case where the game ball is won in the starting port 7 and the case where there is no game ball. That is, the present invention is not limited to the time-division processing as in the present embodiment, but is a program for performing all the processing in one sequence. Since the time is different, the value of the counter P will change. Therefore, in the case of a program that performs all processes in one sequence, the regularity of updating the jackpot random numbers can be accurately diffused by using the value of the counter P.

FIG. 8 shows another embodiment of the above-described jackpot random number generation processing. In this case, the change timing of the added value Q of the random numbers is not limited to one cycle of the random number for the jackpot, but is performed at a random cycle. The other processing is the same as in the above-described embodiment.

In this case, as shown in FIG. 8, the previous random number value stored in the random number storage area is acquired in S51, and in S52, it is determined whether or not it is the timing to change the addition value Q by the X value (using a counter). Good).

In the case of changing timing (X value = 0)
Sets the data corresponding to the value of the counter P created in the remaining time processing of S22 in S53 to the added value Q of the random number, substitutes the timing data R value for the X value in S54, and proceeds to S58. .

When it is not time to change (X value ≠
0) determines whether or not the previous random number value is 0 in S55.

If the previous random number value is 0, the X value is decremented by 1 in S56, and the value of the counter P created in the remaining time processing in S22 is substituted into the timing data R value in S57.
The flow shifts to S58, and if the previous random number value is not 0, the flow directly shifts to S58.

The processing timing of S57 is the same as that of S53.
, The X value and the added value Q are not related.

Steps S58 and thereafter are the same as the processing of FIG. 5, and add Q to the previous random number value and store it in the random number storage area as a new random number value. In S59, it is determined whether or not the new random number value (previous random number value + Q) is equal to or larger than the set value A. If the new random number value is smaller than the set value A, the process returns from the process. On the other hand, if the new random value (previous random value + Q) is equal to or larger than the set value A, the correction process is performed in S60, and the value corrected in the correction process is stored in the random number storage area as a new random value in S61. Remember.

That is, the X cycle of the jackpot random number is updated with the same addition value Q, and when the X cycle ends, a new cycle X and a new addition value Q are set.

In this way, the regularity of updating the jackpot random numbers can be more sufficiently diffused. In this case, since the value of the timing data R for determining the cycle is set using the value of the counter P, it is easy to create a program.

In these embodiments, the regularity of updating is changed every round or several cycles of the random number for jackpot, so that the probability of jackpot is not affected.

[0099]

As described above, according to the first aspect of the present invention, after the progress of a series of game programs based on the interrupt signal, the remaining time until the next interrupt signal is input, that is, the remaining time that varies according to the game condition. Using the correction value that is generated at time and becomes an arbitrary value, every time the random number used for the game becomes the initial value, the added value at the time of updating the random number is set and the random number is updated. Even with a simple configuration in which a random number is created by adding a predetermined value to a value, the regularity of updating the random number can be spread. Therefore, it is possible to prevent an illegal game using the regularity of the update of the random number, for example, using a bodily sensation device or the like that generates vibrations of a fixed cycle, performing electromagnetic wave irradiation, or using an unauthorized device such as a board hanging on the game machine. It can deal with various injustices of playing games by mounting. Further, the random number generation program does not become complicated, the small program size is sufficient, and high reliability can be secured.

According to the second aspect, the time remaining before the next interrupt signal is inputted after the progress of a series of game programs based on the interrupt signal changes by the time-division processing in addition to the game condition. I do. Therefore, the correction value generated in the remaining time becomes a more random value, and the regularity of updating the random number can be sufficiently diffused based on the correction value.
