Abstract

PROBLEM TO BE SOLVED: To effectively protect attack to a game by an illegal board. SOLUTION: Initially, '0' is held as an initial value. When a value of a special prize determining counter proceeds to '249', and 1 is added thereto to return the value to '0', a counter value coinciding with an initial value is detected. A random number 6 to determine the initial value is then extracted. When the counter value to generate the random number 6 at this timing is '19', '19' is extracted as the random number 6, this value is held, and the value is set in the special prize determining counter. The special prize determining counter proceeds from the initial value '19' from this timing.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

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

The variable display section has a plurality of display areas, and is usually configured to display a plurality of variable display results at different times. In the variable display unit, for example,
A plurality of identification information such as symbols are variably displayed. The fact that the display result of the variable display unit is a combination of predetermined specific display modes is usually referred to as “big hit”. In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate. When a "big hit" occurs, for example, a large amount of prize balls and the like are paid out to the player.

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

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

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

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

[0008]

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

Accordingly, an object of the present invention is to provide a gaming machine capable of effectively preventing an attack on a game by an unauthorized board.

On the side of the variable display device 8, a passing gate 11 for guiding a hit ball is provided. The hit ball that has passed through the passing gate 11 is guided to the starting winning opening 14 via the ball exit 13. In a passage between the passage gate 11 and the ball outlet 13, there is a gate switch 12 for detecting a hit ball that has passed through the passage gate 11. In addition, the winning ball that entered the starting winning port 14 is
It is guided to the back of the game board 6 and is detected by the starting port switch 17. In addition, a variable winning ball device 15 that performs opening and closing operations is provided below the starting winning port 14. The variable winning ball device 15 is opened by the solenoid 16.

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

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

The hit ball fired from the hitting ball launching device enters the game area 7 through the hitting rail, and thereafter, the game area 7
Come down. When a hit ball is detected by the gate switch 12 through the passage gate 11, the display number of the variable display 10 is changed continuously. Further, when a hit ball enters the starting winning opening 14 and is detected by the starting opening switch 17, the symbol in the variable display section 9 starts rotating if the symbol can be changed. If it is not possible to start changing the symbol, the start winning memory is increased by one. The start winning memory will be described later in detail.

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

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

Next, the structure of the back surface of the pachinko gaming machine 1 will be described with reference to FIG. On the back of the variable display device 8, as shown in FIG. 2, a prize ball tank 38 is provided above the mechanism plate 36, and when the pachinko gaming machine 1 is installed on the gaming machine installation island, a prize ball is provided from above. Premium ball tank 3

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

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

FIG. 4 is a block diagram showing an example of a circuit configuration of the main board 31. FIG. 4 also shows the prize ball control board 37, the lamp control board 35, the sound control board 70, the emission control board 91, and the display control board 80. On the main board 31, a basic circuit 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 12,
A switch circuit 58 that supplies signals from the starting port switch 17, the V count switch 22, the count switch 23, and the winning ball detection switch 99 to the basic circuit 53, a solenoid 16 that opens and closes the variable winning ball device 15, and the opening and closing plate 2.
A solenoid circuit 59 for driving the solenoid 21 for opening and closing the 0 according to a command from the basic circuit 53;
It includes a lamp / LED circuit 60 for driving the variable display 10 by ED and the decorative lamp 25.

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

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

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

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

Next, the operation will be described. FIG. 5 is a flowchart showing the operation of the basic circuit 53 on the main board 31. As described above, this processing is performed by a reset pulse generated by the periodic reset circuit 66, for example, by 2 m.
It is started every s. When the basic circuit 53 is started, the basic circuit 53 first sets a clock monitor register incorporated in the CPU 56 to a clock monitor enable state in order to make the clock monitor control operable (step S1). The clock monitor control is
When the drop or stop of the input clock signal is detected, the reset is automatically generated inside the CPU 56.

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

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

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

Next, a process for updating each counter for generating each judgment random number such as a big hit judgment random number used for game control is performed (step S10). FIG. 6 is an explanatory diagram showing each random number. Each random number is used as follows. (1) Random 1: Determines whether or not to generate a big hit (for big hit determination) (2) Random 2-1 to 2-3: For left and right middle out-of-design symbol determination (3) Random 3: Design of big hit Determining a combination (for determining a big hit symbol = for determining a specific symbol) (4) Random 4: determining whether or not to reach at the time of a loss (for determining a reach) (5) Random 5: determining a reach type (determining a reach operation) (6) Random 6: Determine the initial value of the counter that generates random 1 (for determining random 1 initial value)

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

Next, the CPU 56 performs a special symbol process (step S11). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S12). In normal symbol processing, 7 segments L
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display 10 by the ED in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state.

The CPU 56 further includes a switch circuit 58
, The state of the gate sensor 12, the starting port sensor 17, and the count sensor 23 are input, and it is determined whether or not there is a prize for each prize port or prize device (switch processing: step S13).

The CPU 56 further performs a process of updating each counter for generating a display random number (step S15). In other words, the counter that generates the random number for determining a lost symbol in (2), the random number for reach determination in (4), and the random number for reach operation in (5) is counted up (1).
Addition). However, random 2-2 is random 2
-1 carry, ie, random 2-
When the value of 1 becomes “15” and returns to “0”, the count is incremented. Random 2-3 is generated when a carry of random 2-2 occurs, that is, random 2
The count is incremented when the value of -2 becomes "15" and is returned to "0".

The CPU 56 performs a winning ball signal process with the winning ball control board 37 (step S16). That is, when a predetermined condition is satisfied, a winning ball number signal is output to the winning ball control board 37. The prize ball control CPU mounted on the prize ball control board 37 drives the ball payout device 97 according to the prize ball number signal.

Thereafter, the basic circuit 53 performs the display random number updating process (the process of incrementing by one) in step S17 and the random 1 control in step S18 until the next reset pulse is given from the periodic reset circuit 66, that is, in an infinite loop. Repeats the counter update process for the server. The random 1 control counter updating process is a process of updating (+1) a random 1 initial value determination counter for generating a random 6. The time required for steps S1 to S16 is 2 ms
Since it is shorter than 2 ms, the display random number update process and the random 1 initial value determination counter update process are repeatedly executed in the remaining time until the time reaches 2 ms. It should be noted that the time required for steps S1 to S16 is different when the game situation is different, so the extra time is not a fixed time. Further, the content of the display random number updating process in step S17 is the same as that in step S1.
5 is the same as the processing of FIG.

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

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

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

The basic circuit 53 performs the processing shown in the flowchart of FIG. 8 when it becomes possible to start the variable display of the image display section 9. First, the value of the number of memorized start winnings is confirmed (step S50). If the start winning prize memory number is not 0, the value stored in the random number storage area corresponding to the start prize storing number = 1 is read out (step S51), the value of the starting prize storing number is reduced by 1, and The value of the random number value storage area is shifted (step S52). That is, the value stored in the random number value storage area corresponding to the number of start winning memory = n (n = 2, 3,...)
It is stored in the random value storage area corresponding to n-1.

Then, the basic circuit 53 proceeds to step S51.
Is determined based on the value read in step 2, ie, the value of the extracted random number for jackpot determination (step S53). In this embodiment, the big hit determination random number takes a value in the range of 0 to 249. Then, as shown in FIG. 9, when the probability is low (when the later-described probable change flag is not set), for example, when the value is “3”, “big hit” is determined, and the value is other than that. In this case, it is determined as “outside”. At the time of the high probability, for example, if the value is any one of “3”, “7”, “79”, “103”, and “107”, it is determined to be “big hit”. Mistake ".

When it is determined that a big hit has occurred, the basic circuit 5
No. 3 determines a stop symbol based on the value of the big hit symbol determining random number (random 3). Here, if the limiter is not operating, a stop symbol is determined from a table including all symbols (steps S54 and S55). If the limiter is operating, a stop symbol is determined from a table that does not include a special symbol (probably variable symbol) in which probability change is performed (steps S54 and S56). The limiter is for restricting the occurrence of the jackpot due to the probable symbol continuously, that is, the continuation of the continuous high probability state. For example, if the high probability state continues four times in a row, the limiter is activated. Therefore, in the limiter operating state, the stop symbol is determined from the table that does not include the special symbol in which the probability change is performed.

Then, the reach type is determined according to the value of the random number 5 (step S74), and whether or not to make a big hit is determined.
The symbol and the reach type in the case of the big hit are set in a predetermined storage area (step S75). The storage area is provided in the RAM 55 of the basic circuit 53.

If it is determined in step S53 that there is a deviation, the CPU 56 determines whether or not to reach (step S59). For example, when the value of the reach determination random number shown in FIG. 6 is any of “0” to “104”, the reach is determined. When determining to reach, the CPU 56 determines a stop symbol. In this embodiment, the left and right symbols are determined according to the value of the random 2-1 (step S60). In addition, the middle symbol is determined according to the value of the random 2-2 (step S61). Here, if the determined middle symbol matches the left and right symbols, the symbol corresponding to the value obtained by adding 1 to the value of the random number corresponding to the middle symbol is determined as the middle symbol, so that it does not match the big hit symbol. I do.

Further, the basic circuit determines a reach type according to the value of the random number 5 (step S62). Then, “reach”, reach symbol, and reach type are set in a predetermined storage area (step S63). If the lottery result in step S59 is out of place, it is set that it is out of place in the predetermined storage area (step S64).

FIG. 10 is a flowchart showing an example of a program for the special symbol process in the basic circuit 53. The special symbol process process shown in FIG. 10 is a specific process of step S11 in the flowchart of FIG. When performing the special symbol process process, the CPU 56 of the basic circuit 53 performs any one of steps S300 to S309 shown in FIG. 10 according to the internal state. In each process, the following processes are performed.

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

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

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

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

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

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

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

Embodiment 1 FIG. 11 is a flowchart of a determination random number update process (step S1) in the main process shown in FIG.
It is a flowchart which shows 0). In the determination random number update process, the CPU 56 increments the value of a counter for generating a random 1 (big hit determination random number) (step S1).
01). If the value of the counter for generating random 1 is (maximum value + 1) (step S102), the counter value is reset to 0 (step S103). In this embodiment, (maximum value + 1) is 250.

Next, the CPU 56 checks whether or not the value of the counter for generating random 1 matches the value stored as the initial value (step S104). If they do not match, the counter value remains unchanged. If they match, random 6 is extracted (step S10).
5). That is, the count value of the counter for generating the random 6 is input. Then, the extracted value is stored as an initial value (step S106), and the extracted value is set in a counter for generating random 1 (step S107). Therefore, at this point, the initial value of the counter that generates random 1 is changed. When the game machine is powered on, “0” is set as an initial value.
Is saved.

Next, the value of the counter for generating the random number 3 (the random number for determining the big hit symbol) is incremented by 1 (step S1).
08). When the value of the counter for generating the random number 3 is (maximum value + 1) (step S109), the counter value is returned to 0 (step S110). In this embodiment, (maximum value + 1) is 15.

FIG. 12 is an explanatory diagram showing an example of the value of a counter that generates a random 1 that changes by the random number updating process for determination shown in FIG. The counter that generates random 1 is cleared to 0 when the power is turned on. Since “0” is initially stored as the initial value, the counter value advances to “249”, and when it is incremented by 1 and the value returns to 0 (steps S101, S102, S103), the processing in step S104 is performed. It is detected that the counter value matches the initial value. Then, random 6 is extracted in the process of step S105. This point is indicated by A in FIG.

Here, it is assumed that the count value of the counter that generates the random number 6 at that time is “19”. Then, “19” is extracted as the random number 6, the value is stored (step S106), and the value is set in the counter that generates the random 1. Therefore, from this point on, the counter that generates random 1 starts increasing from the initial value “19”.

When the value of the counter for generating random 1 becomes "19" again, it is detected in step S104 that the counter value matches the initial value. Then, random 6 is extracted in the process of step S105. In addition,
This point is indicated by B in FIG. The count value of the counter that generates random 6 at that time is “1”.
95 ". Then, "1" as random 6
95 ”is extracted and its value is stored (step S106), and the value is set in a counter that generates random 1. Therefore, from this point, the counter that generates random 1 starts increasing from the initial value “195”.

Then, when the value of the counter for generating random 1 becomes "195" again, it is detected that the counter value coincides with the initial value in the process of step S104. Then, random 6 is extracted in the process of step S105. This point is indicated by C in FIG. It is assumed that the count value of the counter that generates the random 6 at that time is “n”. Then, “n” is extracted as random 6 and its value is stored (step S106), and the value is set in a counter that generates random 1. Therefore, from this point, random 1
Is incremented from the initial value “n”. In FIG. 12, an asterisk (☆) indicates that the counter value is “3”.
(Big hit determination value at low probability). "

As described above, each time the value of the counter for generating random 1 makes one round (250 counts), a new initial value is set as the count value, and thereafter, the counter proceeds from that value. . Counter for generating random 1, that is, a counter for determining the initial value of the jackpot determination counter (counter for generating random 6)
Are counted up in the remaining time of the 2 ms interrupt processing (processing started by the periodic reset signal) in the basic circuit 53. The surplus time differs depending on the progress of the game, and is a random period. As a result, the generated random 6 value is also a random value, so that the initial value of the jackpot determination counter also changes randomly.

That is, every time the value of the big hit determination counter makes one round, the counter starts to advance from a random initial value again. Then, even if the illegal board is connected to the main board 31 and the timing of updating the jackpot determination counter value is recognized based on the signal output from the main board 31, the timing at which the jackpot determination counter value becomes the jackpot determination value is determined. It is difficult to send an incorrect start winning signal to the main board 31 for the purpose. This is because according to this embodiment, as indicated by the star in FIG. 12, the timing at which the jackpot determination counter value becomes the jackpot determination value is not regular but random.

Embodiment 2 In the above-described embodiment, the value of the counter for determining the initial value of the big hit determination counter is counted up in the remaining time of the 2 ms interrupt processing in the basic circuit 53 in order to ensure randomness. However, the initial value updating unit for updating the initial value may have any configuration as long as the randomness of the counter value for determining the initial value is ensured.
For example, if there is a signal in the CPU 56 that is not synchronized with the 2 ms interrupt signal, the value of the counter for determining the initial value may be updated based on the signal.

FIG. 13 shows an example in which a clock signal generated outside the CPU 56 and not synchronized with the periodic reset signal is input to the CPU 56. In the example shown in FIG. 13, a clock signal having a period of 0.89 ms is input from the oscillation circuit 68 to the interrupt terminal of the CPU 56. Since the oscillation circuit 68 is a circuit separate from the periodic reset circuit 66, the clock signal having a period of 0.89 ms is not synchronized with the periodic reset signal.

When a clock is input from the oscillation circuit 68, the CPU 56 performs an interrupt process shown in FIG. In the interrupt processing, the value of the high-speed counter is incremented by 1 (step S
121). When the value of the high-speed counter reaches 250 (step S122), the value is returned to 0 (step S1).
23).

FIG. 15 is a flowchart showing a random number updating process for judgment in this embodiment. As shown in FIG. 15, when the value of the counter that generates random 1 matches the value stored as the initial value (step S104), the value of the high-speed counter is extracted (step S104).
105A), and the value is stored as an initial value (step S106). Other processes are the same as those in the first embodiment.

In this embodiment, the CPU 56 determines the initial value of the jackpot determination counter based on a clock signal that is not synchronized with the periodic reset signal. However, since the cycle of the clock signal is not synchronized with 2 ms, the CPU 56 The count value of the high-speed counter is random with respect to the increment of the determination counter. Therefore, the initial value of the big hit determination counter is also random, and an incorrect start winning signal is sent to the main board in the same manner as in the first embodiment, aiming at the timing when the big hit determination counter value becomes the big hit determination value. It will be difficult to feed into 31.

Embodiment 3 In each of the above embodiments,
When the value of the big hit determination counter makes one round, the initial value changing means changes the initial value of the big hit determination counter. However, the time of updating the initial value is not limited to when the value of the big hit determination counter makes one round, and the initial value of the big hit determination counter may be changed when a plurality of rounds are made.

At this time, if the number of laps at which the timing at which the initial value is changed is not a fixed value but a random value, the random number at the time when the value of the big hit determination counter matches the big hit determination value is obtained. The performance is further improved. In order to perform such a process, for example, as shown in FIG. 16, in this embodiment, a random 7 is used. Random 7
Is a round number determining random number, and is generated by a counter having a value of 1 to m (positive integer). The counter is
Similarly to the random 6 and the like, +1 is added in the random 1 control counter update processing (step S18) of the main processing. When the value becomes (m + 1), it is returned to 1.

FIG. 17 is a flowchart showing a random number updating process for judgment in this embodiment. Step S
The processing of 101 to S104 is the same as that of each of the above embodiments, but in this embodiment, when the value of the extracted random 1 (big hit determination random number) matches the stored initial value. Then, the value of the circulation counter is incremented by 1 (step S131). When the power of the gaming machine is turned on, the value of the lap number counter is set to 0.

Next, the CPU 56 checks whether or not the value of the number-of-turns counter matches the stored number of turns (step S132). If they match, the lap counter is cleared to 0 (step S13).
3) Obtain a counter value for generating a random 7 (step S134). Then, the extracted value is stored as a new number of rounds (step S135). When the power of the gaming machine is turned on, an appropriate value from 1 to m is set as the number of laps (stored value). Other processes are the same as those in the above embodiments.

In this embodiment, when the value of the big hit determination counter circulates by the stored number of laps, the processing of steps S105 to S107, that is, the initial value change processing is executed. The number of turns is determined by the value of the random number 7. Like the random 6, the random 7 is counted up by the remaining time of the 2 ms interrupt processing (processing started by the periodic reset signal) in the basic circuit 53. As described above, the remaining time is a random period because it depends on the progress of the game. As a result, the value of the generated random 7 also becomes a random value, so that the number of turns of the big hit determination counter also becomes random.

Therefore, according to this embodiment, the initial value of the jackpot determination counter is randomly changed, and
The number of turns of the counter that determines the timing for changing the initial value is also changed at random. Therefore, the randomness at the time when the value of the big hit determination counter matches the big hit determination value is further improved, and the generation of an incorrect start winning signal for a big hit by an illegal board or the like can be more effectively prevented.

As described above, according to each of the above embodiments, the initial value of the jackpot determination counter is changed at random, so that the time when the value of the jackpot determination counter matches the jackpot determination value is randomly determined. Become. Therefore, it is difficult to predict the time outside, and the gaming machine is less susceptible to fraud. Also, although the initial value of the jackpot determination counter is changed as appropriate, the count value advances one or more rounds from each initial value, so that the jackpot occurrence probability does not change.

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

The variable display section 9 may be realized by any means, for example, a CRT or LED display, or a drum-type or belt-type variable display device.

Further, in each of the above embodiments, the jackpot determination is performed, the initial value of the jackpot determination counter is changed, and the number of rounds is changed using the extracted random numbers as they are. However, using the extracted random numbers,
Search the contents of the table in which each numerical value according to each random value is set in advance, and use the numerical values searched from the table to determine the jackpot, change the initial value of the jackpot determination counter, and change the round of the jackpot determination counter. The number of times may be determined.

[0084]

As described above, according to the present invention, the initial value value updating means for updating the value of the initial value so that the gaming machine is not synchronized with the update cycle of the value value for the specific game determination, When the numerical value for game determination circulates a predetermined number of times, the configuration is provided with initial value changing means for changing the initial value of the numerical value for specific game determination using the numerical value for initial value, so that it is synchronized with a predetermined start timing Even when observing various signals output from the game control means, it becomes impossible to estimate the timing at which the value for the specific game determination matches the determination value, and as a result,
Since a signal for illegally generating a big hit cannot be given from the outside, it is possible to effectively prevent illegal gaming.

It becomes more difficult to externally estimate the timing at which the numerical value for the specific game determination matches the determination value.

When the initial value updating unit is configured to update the initial value in an infinite loop, the initial value of the specific game determination value is changed at random and the external value is updated. , The update status cannot be grasped, and it becomes more difficult to externally estimate the timing at which the value for the specific game determination matches the determination value.
