Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a game value judging random number value extracted based on the satisfaction of a predetermined condition, and comparing the extracted game value judging random number value with a predetermined judgment value. The present invention relates to a gaming machine for determining a gaming value to be given to a player.

[0002]

2. Description of the Related Art Conventionally, for example, a gaming machine such as a pachinko gaming machine has a counter in an internal memory which is incremented and updated by one at regular intervals, and is provided for satisfying a predetermined condition (for example, winning a starting opening). Based on the counter value, a random value for game value determination (for example, a random number for jackpot determination) is obtained, and the random number for game value determination is compared with a predetermined determination value (for example, a jackpot determination value). The game value (for example, jackpot) to be provided to the player is determined.

[0003]

However, in the above-mentioned conventional gaming machine, when the power is turned on, the update timing of the random value for determining the game value is uniquely determined, so that, for example, an illegal board called a "hanging board" is used. I was worried about cheating. This fraudulent activity using the "hanging board" is based on the power-on timing and the update cycle of the counter, specifying the generation timing of the game value determination random value that matches the determination value, and matching the winning signal with the timing. Is illegally generated (the above-mentioned predetermined condition is satisfied), so that the game value (for example, jackpot)
Is unfairly generated. As a countermeasure, for example, a proposal has been made to use a random number value generated by a random number IC (random number generating device) as a game value determination random number value. However, in this case, although it is considered impossible to capture the generation timing of the random number value that matches the determination value, the random number value itself generated by the random number IC may be manipulated illegally. For example, a signal line extending from the random number IC is illegally operated, and a part of the output is changed to “Lo” or “Hi”.
The improper act of biasing the random number value output from the random number IC (that is, the random value for game value determination) by fixing to any one of these is considered. For example, 8 bits (0 to
255) In the random number IC capable of generating the random number value of
If the signal line corresponding to the bit is disconnected, the range of the random number value output from the random number IC becomes 0 to 127. If the judgment value is in this range, the probability of occurrence of the game value is doubled. If the judgment value does not exist in the range, the probability of occurrence of the game value becomes zero. On the other hand, if the output of the signal line corresponding to the eighth bit is fixed to “Hi”, the random number IC
The range of the random value output from is 128 to 255,
Similarly, the probability of occurrence of the game value changes. As described above, when the random number value generated by the random number IC is used as the random value for game value determination, there is a possibility that the occurrence probability of the game value may be manipulated by an illegal act on the signal line extending from the random number IC.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a gaming machine capable of preventing the probability of occurrence of a gaming value from being manipulated by, for example, a fraudulent activity caused by a hanging board or the like. The purpose is to do.

[0005]

According to an aspect of the present invention, there is provided a game value judging method for generating a game value judging random value (for example, a jackpot judging random value of a special figure). Random number generation means (for example, the game control device 2
0, etc.), and extracts the random value for game value determination based on the satisfaction of a predetermined condition, and compares the extracted random value for game value determination with a predetermined determination value to determine the player value. In a gaming machine (for example, pachinko gaming machine 100 or the like) that determines a gaming value to be given to
A random number generator (for example, a random number IC 22
And the like, and random number value obtaining means (for example, CPU 21a of the game control device 20) for obtaining a random number value from the random number generation device, wherein the game value determination random value generation means includes:
The random number value for game value determination is generated by performing a predetermined operation using a plurality of random number values acquired by the random number value acquisition means as arguments.

According to the first aspect of the present invention, a random value for game value determination is generated by performing a predetermined operation using a plurality of random values obtained from the random number generator as arguments. Therefore, it is difficult to capture the generation timing of the game value determination random number that matches the determination value, or to illegally operate the game value determination random number itself. Therefore, for example, it is possible to prevent the occurrence probability of the game value from being manipulated due to an illegal act caused by a hanging board or the like.

[0007] Here, the gaming machines include pachinko gaming machines, arranged ball gaming machines, sparrow ball gaming machines, etc.
Includes slot machines, pachislots, etc. The game value to be given to the player is, for example, a jackpot state of a special display variable display game in a first-type pachinko gaming machine called a seven machine,
This is a state in which the probability of a variable display game of a special figure varies. Also,
Includes the state of right generation in a third-type pachinko gaming machine called the right thing, the state in which a general electric machine equipped with a plurality of electric things is continuously opened, and the bonus game in a slot machine, etc. It is. The satisfaction of the predetermined condition is, for example, in the case of a so-called first-type or third-type pachinko gaming machine, when a game ball is won at a starting port (starting gate), and in a slot machine, a coin is inserted to start. For example, when the lever is operated. The predetermined operation includes a numerical operation (four arithmetic operations), a logical operation (logical sum, logical product, logical shift, negation, comparison, and the like), or a combination of these operations. You may.

According to a second aspect of the present invention, in the gaming machine according to the first aspect, the random number value obtained by the random number obtaining means is a predetermined bit obtained by combining outputs of a plurality of signal lines extending from the random number generating device. Number, and the game value determination random value generation means selects at least some of the signal lines among the outputs of the plurality of signal lines,
The output of the selected signal line is used at least twice or more to generate the random value for game value determination.

According to the second aspect of the present invention, at least some of the outputs of the plurality of signal lines are selected, and the outputs of the selected signal lines are reduced by at least two.
Since the game value determination random value is generated by using the number of times or more, for example, when there is an abnormality in the output of the selected signal line, it is possible to detect the output abnormality at an early stage. In addition, the determination value can be set in advance so as not to match the random value for game value determination that can be generated in that case.

According to a third aspect of the present invention, in the gaming machine according to the second aspect, a disturbance for determining a game value which can be generated when the output of any one of the selected signal lines is constant. The judgment value was set in advance so as not to match the numerical value.

According to the third aspect of the present invention, the output value of any one of the selected signal lines does not coincide with the random value for game value determination which can be generated when the output is constant. Since the judgment value is set in advance, for example, a part of the output of the random number generator is set to “L” by illegally operating the signal line.
If it is fixed to one of "o" and "Hi", it is not possible to generate a random value for game value determination that matches the determination value. Therefore, it is possible to prevent illegal acts on the signal line extending from the random number generator.

By comparing the random value for game value determination with a determination value stored in the ROM 21c in advance (for example, a jackpot determination value for a special figure, a hit determination value for a common figure), a game value ( For example, a big hit of a special map and a hit of a normal figure are determined, and based on the determination, a display control signal is sent to the display control device 40 and a variable display game (variable display of symbols) is displayed on the variable display section 4a of the special figure. ), Send a sound control signal to the sound control device 60 to control the sound effect output from the speaker, or send a decoration control signal to the decoration control device 50 to turn on the decoration lamps 11,. And control the state.

For example, when the random number for jackpot determination of a special figure matches the jackpot determination value of the special figure, a display control signal is sent to the display control device 40 to variably display the variable display section 4a of the special figure. A predetermined stop mode (for example, “1,1,1”,
(7, 7, 7, etc.) and stop at a big hit. This big hit is a cycle in which the opening and closing door 5a of the special variable winning device 5 is opened and closed for a predetermined time (for example, 29.5 seconds) as one round, and during each round, the game ball is in a continuous winning area in the big winning opening 5b. Is a game that is continued up to a predetermined round (for example, 16 rounds) on condition that the attacker continuation switch 5d detects the attack. However, during each round, when a predetermined number (for example, 10) of game balls are won in the special winning opening 5b, the round is ended at that time. During each round, the number of winnings in the special winning opening 5b is detected by the attacker count switch 5c and stored in the RAM 21b. When the number reaches a predetermined number, the opening / closing door 5a is closed and the special game state of the round ends.

When a detection signal of a winning ball is inputted from the winning opening switches 8a,..., The special figure start switch 9b, and the attacker count switch 5c, the game control device 20 performs discharge control based on the detection signal. A prize ball control command is sent to the device 30 to cause the discharge unit 124 to discharge a required number of prize balls.

FIG. 5 shows a flowchart of a game control process (general flow) performed by the game control device 20.

This game control processing is performed by the CLK generation circuit 24
The processes of steps S1 to S20 are performed one by one based on a reset signal having a predetermined cycle (for example, about 4 ms) generated by the CPU 21a based on the clock signal b. That is, this process is started by the reset signal, and in step S1, a power-on determination process for determining whether or not power is first turned on is performed. If the result of this determination is that the power has been turned on, various registers used by the CPU 21a and the RAM 21b are initialized, and the process proceeds to step S2. If the power is not turned on, the initialization process is omitted, and the process proceeds to step S2. In step S2, after performing an input process for performing logical conversion of a signal input to the interface 23, the process proceeds to step S3.

At step S3, various random numbers related to the variable display game of the special figure and the ordinary figure (for example, the random number value for determining the big hit of the special figure, the random number value for determining the hit of the ordinary figure, the random number value for determining the stop symbol, The CPU 21 generates a reach determination random number, a reach pattern determination random number, a notice determination random number, and the like.
In step a, random number update processing for storing and updating the various random numbers generated in the RAM 21b is performed, and the process proceeds to step S4. Among the various random numbers, the random number value for the big hit determination of the special figure and the random number value for the hit determination of the ordinary figure, which are exemplified as the random value for the game value determination, are generated by a random number generation process (FIG. 6) described later. I do. On the other hand, as for random numbers such as reach determination random numbers that are not directly involved in determining the game value, for example, a counter value that is incremented by one for each sequence of the general flow in FIG. 5 is used as a random number.

In step S4, each winning port switch monitoring process is performed. In each of the winning opening switch monitoring processes, based on input signals from switches such as the general figure start switches 6b and 6b, the special figure start switch 9b, the attacker count switch 5c, and the attacker continuation switch 5d, the special figure start memory and the general figure start switch are set. Processing such as updating the start memory, extracting various random numbers stored and updated in step S3, storing the number of prize balls, and setting round continuation at the time of a big hit is performed.

Next, in a step S5, a special figure game process is performed. In this special figure game process, it is determined whether or not there is a special figure start memory based on a prize in the ordinary variable prize winning device 9. If there is a special figure start memory, the variable display of the special figure extracted in step S4 is performed. By comparing various random numbers related to the game with the corresponding determination values, it is determined whether or not a special figure jackpot is generated, whether or not a reach (reach variable display game) is generated, or stopped. In addition to performing various determinations related to the variable display game of the special figure, such as determining a symbol, a process of decrementing the special figure start memory by one is performed. Then, when the occurrence of the special figure big hit is determined, various processes related to the big hit are performed.

Next, in step S6, a general-purpose game process is performed. In this general-purpose game process, it is determined whether there is a general-purpose start memory based on the detection by the general-purpose start switches 6b, 6b.
By comparing the winning random number value of the ordinary figure and the hit judging value of the ordinary figure, a process of determining whether or not a winning of the ordinary figure occurs is performed. Next, in step S7, according to the determination in step S6, the general-purpose variable display device 7 causes the general-purpose variable display device 7 to perform variable display of the general-purpose figure and stop the same, or to perform time-saving processing. If it is determined in step S6 that the winning of the general figure is determined, a process of opening the normal variable winning device 9 as the general figure winning for a predetermined period is performed. After this processing, the procedure moves to step S8.

In step S8, a fraud monitoring process is performed to monitor for illegal disconnection / short circuit, illegal count, and the like, and then proceeds to step S9. For example, in the monitoring process of no-count irregularity, the attacker count switch 5c detects a state in which no winning ball is detected at all for a predetermined time even though the opening and closing door 5a of the special variable winning device 5 is open. In step S9, after performing a solenoid editing process for editing a control signal to be output to various solenoids (for example, an attacker solenoid 5e, a general-purpose solenoid 6c, etc.), the process proceeds to step S10. In step S10, an external information editing process for editing external information (for example, information relating to a jackpot, probability variation information, etc.) output to an external management device via the game board external output terminal 81 is performed.

Thereafter, a prize ball command editing process for editing a prize ball control command to be sequentially transmitted to the discharge control device 30 (step S11), and a display command editing process for editing a display control signal to be transmitted to the display control device 40 (step S11).

FIG. 6 is a flowchart showing an example of the random number generation processing (step S3) in the general flow of FIG. FIG. 7 is a diagram illustrating the random number generation processing of FIG.

This random number generation process is a process for generating a big hit determination random number value of a special figure, a common figure hit determination random number value, etc. exemplified as a game value determination random number value.
Here, a description will be given using a random number for jackpot determination in a special figure as an example. When this random number generation process is started, first, in step S31, the random number IC 22
A process of acquiring the random number value of the bit and storing it in the RAM 21b is performed, and the process proceeds to step S32. At this time, RA
In M21b, a currently acquired random number value acquired this time and a previously acquired random number value acquired last time are stored. Step S
At 32, the upper 4 bits of the previously obtained random number value stored in the RAM 21b are cleared, and then the whole is shifted left by 4 bits. For example, the previously obtained random number value is “0100010”
In the case of “1” (B), the upper 4 bits are cleared to “0”.
0000101 ", the whole is shifted left by 4 bits to obtain" 01010000 ". Next, step S3
At 3, the upper 4 bits of the currently obtained random number value stored in the RAM 21b are cleared. For example, when the currently acquired random number value is “01100010” (B), the upper 4 bits are cleared to “00000010”. Then
In step S34, a logical sum of the operation result in step S32 and the operation result in step S33 is calculated to generate a random number for jackpot determination in a special figure. For example,
When the logical sum of “01010000” and “00000010” is calculated, the special figure jackpot random number value is “01010110”.
Becomes Next, in step S35, step S34
After updating the calculation result in the RAM 21b, the flow returns to the general flow random number generation processing (step S3) in FIG.

That is, according to the above random number generation processing, FIG.
As shown in FIG. 7A, the upper four bits (B7, B6, B5, B4) of the generated random number for jackpot determination in the special map are the previously acquired random number (the first acquired random number in FIG. 7A). b
n_1), the lower four bits (b3_1, b2_1, b1_1, b0_1) of the random number value for jackpot determination (B3, B2, B1, B0) are composed of the lower four bits (b3_1, b2_1, b1_1, b0_1) It consists of the lower 4 bits (b3_2, b2_2, b1_2, b0_2) of the second acquired random number value bn_2).

Here, as shown in FIG. 7B, the jackpot determination value used to determine the random number for jackpot determination is:
The random number for jackpot determination that can be generated when any one of the lower four bits b0, b1, b2, and b3 of the random number used for generation of the random number for jackpot determination is constant (for example, FIG. (E.g., "10010101" shown in (b)). That is, the seventh bit and the third bit of the judgment value are set to different values, and similarly, the sixth bit and the second bit, the fifth bit and the first bit, and the fourth bit and the 0th bit have different values. Is set to For example, as shown in FIG.
0001111 "and" 00101101 "are set as the jackpot determination values. Therefore, for example, a part of the output of the random number IC 22 is changed to “Lo” by illegally operating the signal line.
If it is fixed to either (0) ”or“ Hi (1) ”, it is not possible to generate a jackpot determination random value that matches the jackpot determination value. Therefore, the random number IC22
Fraud on the signal line extending from the terminal can be prevented.

In the random number generation process, the random number IC2
The random number value for jackpot determination is generated using the lower 4 bits of the two random number values obtained from 2. For example,
It is also possible to use three or more random numbers for the jackpot determination random number, or to change the bit position and the number of bits of the random number used for the jackpot determination random number. Further, the calculation method applied to the generation of the random number for jackpot determination is not limited to the above calculation method, and various variations may be possible. For example, as shown in FIG. 8, four random number values bn_1, bn_2, bn_
3, bn_4, the exclusive OR of each bit of these random numbers is obtained, and this is used as a random number for jackpot determination. The four random numbers bn_1, bn are obtained from the random number IC22.
_2, bn_3, and bn_4, and a method of obtaining the sum of these random numbers as a random number for jackpot determination. The four random numbers bn_1, bn_ obtained from the random number IC22.
2, random number value bn_ from among bn_3 and bn_4
2, bn_4, and these random number values bn_2, bn_
4, a method of calculating an exclusive OR of each bit of 4 and using this as a random number for jackpot determination. Of course, it is also possible to apply various operation methods other than these (numerical operation (four arithmetic operations), logical operation (logical addition, logical product, logical shift, negation, comparison, etc.), or a combination of these operations). .

According to the pachinko gaming machine 100 of this embodiment, by performing a predetermined operation using a plurality of random number values obtained from the random number IC 22 as arguments, the random value for game value determination (the jackpot of the special figure) (Such as a random number for judgment and a random number for hit judgment in ordinary maps)
It becomes difficult to capture the generation timing of the game value determination random number that matches the determination value, or to illegally manipulate the game value determination random number itself. Therefore, for example, it is possible to prevent the occurrence probability of the game value (big hit of a special figure or hit of a normal figure) from being manipulated due to an illegal act by a hanging board or the like.

The output of at least some of the plurality of signal lines extending from the random number IC 22 is selected, and the output of the selected signal line is used at least twice to generate a game value determination disturbance. Since the numerical value is generated, for example, when there is an abnormality in the output of the selected signal line, the output abnormality can be detected early. In addition, since the judgment value is set in advance so as not to coincide with the random value for game value judgment that can be generated in that case, for example, the signal line is illegally operated by the random number IC 22 and the output of the random number generation device is output. Is fixed to one of “Lo” and “Hi”, it is not possible to generate a random value for game value determination that matches the determination value. Therefore,
Unauthorized acts on the signal line extending from the random number IC 22 can be prevented.

The present invention is not limited to the pachinko gaming machine 100 of this embodiment. For example, other pachinko gaming machines, arranging ball gaming machines, ball-ball gaming machines such as sparrow ball gaming machines, or slots. It is also applicable to machines, pachislots, and the like. Further, in this embodiment, the random value for game value determination is a random number for jackpot determination in a special figure or a random number for hit determination in a common figure, but other random numbers may be used. Further, the random number IC is exemplified as the random number generation device, but the present invention is not limited to this. For example, the number of digits of the random number to be output and the output timing of the random number can be appropriately changed. Although the random number IC is provided inside the game control device 20, the game control device 2
0 may be provided outside. In addition, the embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

[0050]

According to the first aspect of the present invention, a random value for game value determination is generated by performing a predetermined operation using a plurality of random values obtained from the random number generator as arguments. Therefore, it is difficult to capture the generation timing of the game value determination random value that matches the determination value, or to illegally manipulate the game value determination random value itself. Therefore, for example, it is possible to prevent the occurrence probability of the game value from being manipulated due to an illegal act caused by a hanging board or the like.

According to the second aspect of the present invention, the output of at least some of the plurality of signal lines is selected, and the output of the selected signal line is used at least twice or more. Since the value determination random value is generated, for example, if there is an abnormality in the output of the selected signal line, the output abnormality can be detected early.
In addition, the determination value can be set in advance so as not to match the random value for game value determination that can be generated in that case.

According to the third aspect of the present invention, it is determined that the output of any one of the selected signal lines does not coincide with the random value for game value determination that can be generated when the output of the signal line is constant. Since the value is set in advance, for example, a part of the output of the random number generator is “Lo” by illegally operating the signal line.
Alternatively, if the value is fixed to either one of “Hi”, it is not possible to generate a random value for game value determination that matches the determination value. Therefore, it is possible to prevent illegal acts on the signal line extending from the random number generator.
