Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, and in particular, when a game is performed by a player's operation and a predetermined condition is satisfied, the specific game can be performed, and the result of the specific game is a predetermined mode. The present invention relates to a gaming machine that can give a predetermined game value to a player based on the fact that the game has been completed.

  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 prize area such as a prize opening provided in the game area, a predetermined number of prize balls are paid out to the player. There is something to be done. Further, a variable display unit capable of changing the display state is provided, and is configured to give a predetermined game value to the player when the display result of the variable display unit becomes a predetermined specific display mode There is.

  The variable display section has a plurality of display areas, and is usually configured to display the display results of the plurality of variable displays at different times. For example, a plurality of pieces of identification information such as symbols are variably displayed on the variable display section. That the display result of the variable display unit is a combination of specific display modes determined in advance is usually called “big hit”. Note that the game value is the right that the state of the variable winning ball device provided in the gaming area of the gaming machine is advantageous for a player who is likely to win a ball, or the advantageous state for a player. It is to generate. When a “hit” occurs, for example, a player is given a value such as a large number of prize balls.

  In game control in such a gaming machine, a random number is generated when a predetermined condition (for example, a start prize that becomes a variable display start condition) is satisfied, and a “big hit” when the random number value matches a predetermined value. It becomes. In addition, a circuit portion that performs game control for reasons such as noise countermeasures 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 update of the counter value is performed in the circuit portion that performs the game control, the generated random number value is the time interval of activation of the circuit portion that performs the game control. I have to synchronize.

  Then, when the activation time interval is detected by some means, the counter value update timing is recognized. Furthermore, the timing at which a random value that is a “big hit” is recognized is recognized. Then, it becomes possible to frequently generate a “hit” by aiming for a start winning prize at a timing when a random value that becomes a “hit” is generated.

  An illegal board may be attached to the gaming machine in order to detect the start timing of the circuit portion that performs game control. Such a fraudulent board introduces a signal output to the outside from the circuit part that performs game control, detects the activation timing of the circuit part that performs game control based on the signal, and generates a random number value that causes a “hit” The timing of occurrence is detected. Then, the illegal board can illegally generate a “hit” by sending a start winning signal to the circuit portion that controls the game at that timing.

  For example, a display control board on which a display control microcomputer for controlling the display state of the variable display unit is mounted has a display control command for changing the display state from a main board on which a circuit for performing game control is mounted. Sent out. As described above, the circuit portion that performs game control is reset every 2 ms, for example, and therefore the display control command transmission interval is synchronized with 2 ms. A "big hit" is made after an illegal board is connected between the main board and the display control board, and the counter value update timing is recognized based on the display control command sending interval, for example, by introducing an original start winning signal. If an illegal start winning signal is sent to the main board in order to generate a random number value that will cause a "big hit", an illegal "big hit" will occur.

  Since various components such as a variable display device, a decorative lamp, and a sound generator are present in the gaming machine, it is not possible to eliminate signal lines from the circuit portion that performs game control to those components. Accordingly, there remains a room where the illegal board as described above is attached and illegal gaming acts are performed. Therefore, how to prevent an illegal gaming act using an illegal board is an important issue in the gaming machine.

  In view of the above, an object of the present invention is to provide a gaming machine that can effectively prevent an attack against a game by an unauthorized board.

A gaming machine according to the present invention is a gaming machine that is capable of playing a game based on a player's operation and being able to shift to a specific gaming state that is advantageous to the player, the value of a specific game determination counter within a predetermined numerical range Specific game determination counter update means for updating the game, and a game control for extracting the value of the specific game determination counter when a predetermined condition is satisfied, comparing the extracted value with the determination value, and shifting to the specific game state when they match Means, initial value determination counter updating means for updating the value of the initial value determination counter for determining the initial update value of the specific game determination counter, and the value of the specific game determination counter has become a predetermined value. with extracts the value of the initial value determination counter specific game determining counter stored until a predetermined orbit in a condition, identified based on the value of the initial value determination counter to the storage Numerology for determining an initial value updating means skill determination counter is set to an initial value to a specific game determining counter when a predetermined orbit, a predetermined value which is a timing at which the value of the initial value determination counter is extracted The initial value update means performs an arithmetic process using the stored initial value determination counter value, sets the calculation result as an initial value in the specific game determination counter, and the numerical value determination means determines the initial value determination Is a means for updating a counter different from the counter for use with an update condition different from that for the initial value determination counter, and a predetermined value for updating the value of the predetermined value determination counter within the same numerical range as the specific game determination counter A determination counter updating means; and an extraction storage means for extracting the value of the predetermined value determination counter when the specific game determination counter makes a predetermined number of revolutions and storing the extracted value as a predetermined value. Those were.

According to the present invention, the gaming machine stores the value of the initial value determination counter on the condition that the value of the specific game determination counter reaches a predetermined value and stores the value until the specific game determination counter makes a predetermined number of laps. And initial value updating means for setting an initial value in the specific game determination counter when the specific game determination counter makes a predetermined number of turns based on the stored initial value determination counter value. However, since it is configured to perform arithmetic processing using the stored initial value determination counter value and set the arithmetic result as the initial value in the specific game determination counter, the game control means is synchronized with a predetermined activation timing. Observing the various signals output from the game, it is no longer possible to guess when the numerical value for the specific game decision matches the decision value, resulting in illegal jackpots from the outside Signal no longer can give for an effect of effectively preventing illegal gaming activities.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the overall configuration of a pachinko gaming machine that is an example of a gaming machine will be described. 1 is a front view of the pachinko gaming machine 1 as seen from the front, FIG. 2 is an overall rear view showing the internal structure of the pachinko gaming machine 1, and FIG. 3 is a rear view of the gaming board of the pachinko gaming machine 1 as seen from the back. Here, a pachinko gaming machine is shown as an example of a gaming machine, but the present invention is not limited to a pachinko gaming machine, and may be, for example, a coin gaming machine.

  As shown in FIG. 1, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape. On the lower surface of the glass door frame 2 is a hitting ball supply tray 3. Below the hitting ball supply tray 3, there are provided an extra ball receiving tray 4 for storing prize balls overflowing from the hitting ball supply tray 3 and a hitting operation handle (operation knob) 5 for firing the hitting ball. A game board 6 is detachably attached to the rear side of the glass door frame 2. A game area 7 is provided in front of the game board 6.

  Near the center of the game area 7, there is provided a variable display device 8 including a variable display section 9 for variably displaying a plurality of kinds of symbols and a variable display 10 using 7 segment LEDs. In this embodiment, the variable display section 9 has three symbol display areas of “left”, “middle”, and “right”. A passing gate 11 for guiding a hit ball is provided on the side of the variable display device 8. The hit ball that has passed through the passing gate 11 is guided to the start winning opening 14 through the ball outlet 13. In the passage between the passage gate 11 and the ball exit 13, there is a gate switch 12 that detects a hit ball that has passed through the passage gate 11. The winning ball that has entered the start winning opening 14 is guided to the back of the game board 6 and detected by the start opening switch 17. A variable winning ball device 15 that opens and closes is provided below the start winning opening 14. The variable winning ball device 15 is opened by a solenoid 16.

  An open / close plate 20 that is opened by a solenoid 21 in a specific gaming state (big hit state) is provided below the variable winning ball device 15. In this embodiment, the opening / closing plate 20 is a means for opening and closing the special winning opening. Of the winning balls guided from the opening / closing plate 20 to the back of the game board 6, the winning ball entering one (V zone) is detected by the V count switch 22. A winning ball from the opening / closing plate 20 is detected by the count switch 23. At the bottom of the variable display device 8, a start winning memory display 18 having four display units for displaying the number of winning balls that have entered the start winning opening 14 is provided. In this example, with the upper limit being four, each time there is a start prize, the start prize storage display 18 increases the number of lit display units one by one. Then, each time the variable display of the variable display unit 9 is started, the lit display unit is reduced by one.

  The game board 6 is provided with a plurality of winning openings 19, 24. Decorative lamps 25 blinking during the game are provided around the left and right sides of the game area 7, and an outlet 26 for absorbing a hit ball that has not won a prize is provided below. Two speakers 27 that emit sound effects are provided on the left and right upper portions outside the game area 7. On the outer periphery of the game area 7, a game effect LED 28a and game effect lamps 28b and 28c are provided.

  In this example, a prize ball lamp 51 that is lit when the prize ball is paid out is provided in the vicinity of one speaker 27, and a ball break lamp 52 that is lit when the supply ball is cut is provided in the vicinity of the other speaker 27. Is provided. Further, FIG. 1 also shows a card unit 50 that is installed adjacent to the pachinko gaming machine 1 and enables lending of a ball by inserting a prepaid card.

  The card unit 50 has a usable indicator lamp 151 indicating whether or not it is in a usable state, and when the remaining amount information recorded in the card has a fraction (a number less than 100 yen), the fraction is indicated as a hitting tray. 3, a fraction display switch 152 for displaying on a frequency display LED provided in the vicinity of 3, a connecting table direction indicator 153 indicating which side of the pachinko gaming machine 1 corresponds to the card unit 50, in the card unit 50 Check the card insertion indicator lamp 154 indicating that a card is inserted, the card insertion slot 155 into which a card as a recording medium is inserted, and the mechanism of the card reader / writer provided on the back of the card insertion slot 155. In some cases, a card unit lock 156 is provided for releasing the card unit 50.

  The hit ball fired from the hit ball launching device enters the game area 7 through the hit ball rail, and then descends the game area 7. When the hit ball is detected by the gate switch 12 through the passing gate 11, the display number of the variable display 10 changes continuously. Further, when the hit ball enters the start winning opening 14 and is detected by the start opening switch 17, the symbol in the variable display portion 9 starts to rotate if the variation of the symbol can be started. If it is not in a state where the change of the symbol can be started, the start winning memory is increased by one. The start winning memory will be described in detail later.

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

When the combination of images in the variable display section 9 at the time of stop is a combination of jackpot symbols with probability fluctuations, the probability of the next jackpot increases. That is, it becomes a more advantageous state for the player in a high probability state.
Further, when the stop symbol on the variable display 10 is a predetermined symbol (winning 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 in the variable display 10 becomes a winning symbol is increased, and the opening time and the number of times of opening of the variable winning ball device 15 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 surface of the variable display device 8, as shown in FIG. 2, a prize ball tank 38 is provided above the mechanism plate 36, and the prize ball is placed from above in a state where the pachinko gaming machine 1 is installed on the gaming machine installation island. It is supplied to the prize ball tank 38. The prize balls in the prize ball tank 38 pass through the guide rod 39 and reach the ball dispensing device.

  The mechanism plate 36 includes a variable display control unit 29 for controlling the variable display unit 9 via the relay board 30, a game control board (main board) 31 covered with a board case 32 and mounted with a game control microcomputer, etc. A relay board 33 for relaying signals between the variable display control unit 29 and the game control board 31, and a prize ball control board 37 on which a prize ball control microcomputer for performing payout control of prizes is mounted. Has been. Further, the mechanism plate 36 includes a ball hitting device 34 that uses the rotational force of the motor to hit the game area 7, game effect lamps / LEDs 28 a, 28 b, 28 c, prize ball lamps 51, and ball break lamps 52. A lamp control board 35 for sending signals is installed.

  FIG. 3 is a rear view of the game board of the pachinko gaming machine 1 as seen from the back. On the back surface of the game board 6, as shown in FIG. 3, a winning ball collective cover 40 is provided for guiding the winning balls that have won the winning holes and the winning ball devices along a predetermined winning path. Among the winning balls led to the winning ball collective cover 40, those that win through the opening / closing plate 20 pay out a relatively large number of prize balls (for example, 15) by a ball paying device (not shown in FIG. 3). To be controlled. Those that win a prize 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). And what was won through the other winning opening 24 and the winning ball device is controlled such that the ball payout device pays out a relatively medium number of prize balls (for example, 10). In FIG. 3, the relay board 33 is illustrated.

  In order to perform the winning ball payout control, signals from the winning ball detection switch 99, the start port switch 17 and the V count switch 22 are sent to the main board 31. A winning ball is detected by the winning ball detection switch 99, but when the 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. It is done. For example, when the winning ball detection switch 99 is turned on in response to the start port switch 17 being turned on, a winning ball control command indicating the number of winning balls “6” is output, corresponding to turning on the count switch 23 or the V count switch 22. When the winning ball detection switch 99 is turned on, a winning ball control command indicating the number of winning balls “15” is output. If the winning ball detection switch 99 is turned on when those 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 illustrating an example of a circuit configuration in the main board 31. FIG. 4 also shows a prize ball control board 37, a lamp control board 35, a sound control board 70, a launch control board 91, and a display control board 80. On the main board 31, a basic circuit 53 that controls the pachinko gaming machine 1 according to a program, and signals from the gate switch 12, the start port switch 17, the V count switch 22, the count switch 23, and the winning ball detection switch 99 are input to the basic circuit 53. Switch circuit 58 applied to the motor, solenoid 16 for opening / closing the variable winning ball apparatus 15 and solenoid circuit 59 for driving the solenoid 21 for opening / closing the opening / closing plate 20 in accordance with a command from the basic circuit 53, and turning on / off of the start memory display 18 A lamp / LED circuit 60 for driving the variable display 10 by the 7-segment LED and the decorative lamp 25 is included.

  Further, according to the data given from the basic circuit 53, the jackpot information indicating the occurrence of the jackpot, the effective starting information indicating the number of starting winning balls used for starting the image display of the variable display unit 9, and the fact that the probability variation has occurred. An information output circuit 64 is provided for outputting the probability variation information and the like to a host computer such as a hall management computer.

  The basic circuit 53 includes a ROM 54 that stores a game control program and the like, a RAM 55 that is used as a work memory, a CPU 56 that performs a control operation according to a control program, and an I / O port unit 57. Note that the ROM 54 and RAM 55 may be built in the CPU 56.

Further, an initial reset circuit 65 for resetting the basic circuit 53 when the power is turned on is provided on the main board 31, and a reset pulse is given to the basic circuit 53 periodically (for example, every 2 ms) to start a game control program. A reset circuit 66 for re-execution from the start address, and an address for outputting a signal for selecting any I / O port of the I / O port unit 57 by decoding the address signal given from the basic circuit 53 A decoding circuit 67 is provided.
Note that there is also switch information input to the main board 31 from the ball dispensing device 97, but these are omitted in FIG.

  A ball hitting device for hitting and launching a game ball is driven by a drive motor 94 controlled by a circuit on the launch control board 91. Then, the driving force of the drive 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 main operation of the game control program executed by the CPU 56 on the main board 31. As described above, this processing is started, for example, every 2 ms by a reset pulse generated by the periodic reset circuit 66. When the CPU 56 is activated, the CPU 56 first sets a clock monitor register built in the CPU 56 to a clock monitor enable state in order to enable clock monitor control (step S1). Note that the clock monitor control is a control that automatically generates a reset within the CPU 56 when a drop or stop of the input clock signal is detected.

  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 an error is included in the RAM 55. If the error is included, the CPU 56 performs a process such as initializing the RAM 55.

  Next, after performing a process of setting a display control command sent to the display control board 80 in a predetermined area of the RAM 55 (display control data setting process: step S4), a process of outputting a display control command is performed (display) Control data transmission process: Step S5).

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

Next, a process of updating each counter for generating each determination random number such as a big hit determination 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: Decide whether or not to generate a big hit (for big hit judgment)
(2) Random 2-1-2-3: For left / right centered symbol determination (3) Random 3: Determines the symbol combination at the time of jackpot (for jackpot symbol determination = for specific symbol determination)
(4) Random 4: Decide whether or not to reach when falling off (for reach determination)
(5) Random 5: Reach type is determined (for reaching operation determination)
(6) Random 6: Determines the initial value of the counter for generating random 1 (for determining random 1 initial value)

  Here, random 6 is a random number for determining a value newly set in the counter for generating random 1 when the counter value for generating random 1 circulates a predetermined number of times. The range of each random number shown in FIG. 6 is an example, but even when a range different from the random number range shown in FIG. 6 is used, the range that random 6 can take is the same as the range that random 1 can take. Set to

In order to enhance the game effect, random numbers other than the random numbers (1) to (6) are also used. In addition, in order to enhance the gaming effect, the variable display unit 9 also displays images other than symbols, such as a background or a character that performs a predetermined movement.
In step S10, the CPU 56 counts up (adds 1) a counter for generating the jackpot determination random number (1) and the jackpot symbol determination random number (3).

  Next, the CPU 56 performs special symbol process processing (step S11). In the special symbol process control, corresponding processing is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state. Also, normal symbol process processing is performed (step S12). In the normal symbol process, the corresponding process is selected and executed in accordance with the normal symbol process flag for controlling the variable display 10 using the 7-segment LED in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Further, the CPU 56 inputs the states of the gate sensor 12, the start port sensor 17 and the count sensor 23 via the switch circuit 58, and determines whether or not each winning port or winning device has been won (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 for generating the random symbol for determining the symbol of (2), the random number for determining the reach of (4), and the random number for the reaching operation of (5) is incremented (added by 1). However, the random 2-2 is counted up when the carry of the random 2-1 occurs, that is, when the value of the random 2-1 becomes “15” and is returned to “0”. Random 2-3 is counted up when a carry of random 2-2 occurs, that is, when the value of random 2-2 becomes “15” and returns to “0”.

  And the process which updates the random number for random 1 initial value determination is performed (step S16). That is, the counter for generating the random 1 initial value determining random number is incremented by one.

  Further, the CPU 56 performs a winning ball signal process with the winning ball control board 37 (step S17). That is, when a predetermined condition is satisfied, a prize ball number signal is output to the prize 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, until the next reset pulse is supplied from the periodic reset circuit 66, that is, in an infinite loop, the CPU 56 performs a random number update process for displaying (adding +1) in step S18 and a random random number for determining a random 1 initial value in step S19. Repeat the process. Since the time required for steps S1 to S17 is shorter than 2 ms, the display random number update process and the random 1 initial value determination counter update process are repeatedly executed with the remaining time until reaching 2 ms. Note that the time required for steps S1 to S17 differs depending on the game situation, so the surplus time is not a fixed time. Further, the content of the display random number update process in step S18 is the same as the process in step S15, and the content of the random 1 initial value determination random number update process in step S19 is the same as the process in step S16.

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

  When the hit ball wins the start winning opening 14 provided in the game board 6, the start opening switch 17 is turned on. When the CPU 56 detects that the start port switch 17 is turned on via the switch circuit 58 and the I / O port 57 (step S41), it confirms whether or not the start winning memory number has reached the start memory upper limit value (step S42). ). If the starting winning memory number does not reach the starting memory upper limit value, the starting winning memory number is increased by 1 (step S43). In this embodiment, the starting storage upper limit value is 4.

  And the value of the counter for generating random 1 is extracted, and the extracted value is provided corresponding to each start winning memory number n (n = 1, 2, 3,..., Start memory upper limit value). Stored in the stored random value storage area (step S44). Note that if the start winning memory number has reached the start memory upper limit value, the processing of steps S43 to S44 is not performed.

When the CPU 56 is ready to start variable display on the image display unit 9, the CPU 56 performs the processing shown in the flowchart of FIG.
First, the value of the start winning memory number is confirmed (step S50). If the starting winning memory number is not 0, the value stored in the random number value storage area corresponding to the starting winning memory number = 1 is read (step S51), the value of the starting winning memory number is decreased by 1, and each The value in the random value storage area is shifted (step S52). That is, the value stored in the random number value storage area corresponding to the starting winning memory number = n (n = 2, 3,...) Is stored in the random number value storing area corresponding to the starting winning memory number = n−1. Store.

  Then, the CPU 56 determines the winning / losing based on the value read in step S51, that is, the value of the extracted big hit determination random number (step S53). In this embodiment, the jackpot determination random number takes a value in the range of 0-299. Then, as shown in FIG. 9, when the probability is low (when the probability variation flag described later is not set), for example, when the value is “3”, it is determined as “big hit”, and other values are set. In this case, it is determined as “out of”. When the probability is high, for example, when the value is any one of “3”, “7”, “79”, “103”, “107”, “big hit” is determined. It is determined that it is out of place.

  When it is determined that the game is a big hit, the CPU 56 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, the stop symbol is determined from the table including all symbols (steps S54 and S55). When the limiter is operating, a stop symbol is determined from a table that does not include a special symbol (probability variation symbol) in which probability variation is performed (steps S54 and S56). The limiter is intended to limit the occurrence of big hits due to the probability variation pattern, that is, the continuous high probability state. For example, when the high probability state continues four times, the limiter is activated. Therefore, in the limiter operating state, a stop symbol is determined from a table that does not include a special symbol for which probability variation is performed.

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

  If it is determined in step S53 that there is a divergence, 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 one of “0” to “104”, the reach is determined. When it is determined to reach, the CPU 56 determines a stop symbol. In this embodiment, the left and right symbols are determined according to the value of random 2-1 (step S60). Further, the medium symbol is determined according to the value of random 2-2 (step S61). Here, when the determined middle symbol matches the left and right symbols, the symbol corresponding to the value obtained by adding 1 to the random number value corresponding to the middle symbol is set as the determined symbol of the middle symbol so as not to match the jackpot symbol To do.

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

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

Special symbol variation waiting process (step S300): Waiting for the start opening sensor 17 to be turned on after hitting the start winning opening 14 (the winning opening of the variable winning ball apparatus 15 in this embodiment). When the start opening sensor 17 is turned on, if the start winning memorized number is not full, the start winning memorized number is incremented by 1 and a big hit determination random number is extracted. That is, the process shown in FIG. 7 is executed.
Special symbol determination process (step S301): When variable symbol special display can be started, the number of start winning memories is confirmed. If the starting winning memorization number is not 0, it is determined whether to win or not depending on the value of the extracted jackpot determination random number. That is, the first half of the process shown in FIG. 8 is executed.
Stop symbol setting process (step S302): The stop symbol of the middle left and right symbols is determined. That is, the middle half of the process shown in FIG. 8 is executed.

  Reach operation setting process (step S303): It is determined whether or not a reach operation is performed according to the value of the reach determination random number, and a variation mode of the reach operation is determined according to the value of the reach operation random number. That is, the second half of the process shown in FIG. 8 is executed.

  All symbol variation start processing (step S304): Control is performed so that the variation display unit 9 starts variation of all symbols. At this time, the left / right middle final stop symbol and the information for instructing the variation mode are transmitted to the display control board 80. Further, when a background or 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 sent to the display control board 80.

  All symbols stop waiting process (step S305): When a predetermined time has elapsed, control is performed so that all symbols displayed on the variable display unit 9 are stopped. Also, control is performed so that the left and right symbols are stopped at a predetermined timing until the timing of all symbols stop. Further, control is performed so that display control command data corresponding to the background or character displayed on the variable display unit 9 is sent to the display control board 80 as appropriate.

Jackpot display processing (step S306): When the stop symbol is a combination of jackpot symbols, control is performed so that display control command data for jackpot display is sent to the display control board 80, and the internal state (process flag) is stepped. Update to shift to S307. If not, the internal state is updated to shift to step S309. The jackpot symbol combination is a combination of right and left middle symbols. Further, the display control CPU of the game control board 80 displays a big hit on the variable display unit 9 in accordance with 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 for opening a special prize opening (step S308): Control for sending display control command data for the big prize opening round display to the display control board 80, processing for confirming establishment of a closing condition for the special prize opening, and the like. If the closing condition for the big prize opening is satisfied, the internal state is updated to shift to step S307 if the end condition for the big hit gaming state is not satisfied. If the end condition for the big hit gaming state is satisfied, the internal state is updated to shift to step S309.

  Jackpot end process (step S309): A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flag and the like are returned to the initial state, and the internal state is updated to shift to step S300.

Embodiment 1 FIG.
FIG. 11 is a flowchart showing the determination random number update process (step S10) in the main process shown in FIG. In the determination random number update process, the CPU 56 increments the value of the counter that generates random 1 (big hit determination random number) by 1 (step S101). When the value of the counter for generating random 1, that is, the jackpot determination counter is (maximum value + 1) (step S102), the counter value is returned to 0 (step S103). In this embodiment, since random 1 takes a value in the range of 0 to 299, (maximum value + 1) is 300.

  Next, the CPU 56 checks whether or not the value of the jackpot determination counter matches a predetermined value s determined in advance (step S104). If they match, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted (step S105), and the extracted value is stored in a predetermined area of the RAM 55 (step S106). Hereinafter, the stored value is referred to as a stored value. The predetermined value s is set to an appropriate value (150 in this example) when the power is turned on, for example. This value may be changed every time power is turned on. Further, in the case where the process of step S104 is performed prior to the update process of step S101, if the initial value of the predetermined value s is set to 0, a period in which the value is 0 may continue for a while. The numerical value of the predetermined value s set when the power is turned on is preferably not 0.

  Further, the CPU 56 checks whether or not the value of the big hit determination counter matches the round determination value (step S107). The round determination value will be described later. If they match, the stored value is set as an initial value in the jackpot determination counter (step S108), and the stored value is set as the round determination value (step S109).

The round determination value is a value stored in a predetermined area of the RAM 55, and is used to determine the timing at which the value of the big hit determination counter is updated to a random 6 value. Since the same value is set for the round trip judgment value when the big hit judgment counter starts stepping from a new initial value (value when the stored value is set), the counter value is counted when the big hit judgment counter makes a round. Corresponds to the round-trip determination value. That is, the one-round determination value is a value for detecting that the count of the big hit determination counter has made one round.
When the power is turned on, the one-round determination value is initialized to zero.

  Next, +1 is added to the value of the counter for generating random 3 (a jackpot symbol determining random number) (step S130). When the value of the counter that generates the random number 3 is (maximum value + 1) (step S131), the counter value is returned to 0 (step S132). In this embodiment, (maximum value + 1) is 15.

  FIG. 12 is an explanatory diagram showing an example of the value of the jackpot determination counter that is changed by the determination random number update process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. Remembered. That is, a random value of 6 is stored. In this example, the predetermined value s is 150, but the value can be arbitrarily set.

  When the value of the big hit determination counter advances to “299” and is incremented by 1 and the value returns to 0 (steps S101, S102, S103), it is detected that the counter value matches the round determination value in the process of step S107. The Then, in the process of step S108, the stored value is set in the big hit determination counter. At the same time, the stored value is also set as the one-round determination value (step S109). In the example shown in FIG. 12, the stored value at this time is “19”. Therefore, from this point, the big hit determination counter advances from the initial value “19”.

  When the value of the big hit determination counter again reaches “predetermined value s”, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the big hit determination counter reaches “19”, it is detected in step S107 that the counter value matches the round determination value. Then, in the process of step S108, the stored random value “195” is set as a new initial value in the jackpot determination counter. Therefore, from this point, the big hit determination counter advances from the initial value “195”.

  Then, when the value of the jackpot determination counter again advances to “predetermined value s”, random 6 (= P) is extracted and stored. Then, when the value of the jackpot determination counter reaches “195”, the counter value matches the round determination value. Therefore, in the process of step S108, the stored random value “P” is added to the jackpot determination counter. Set as initial value. Therefore, from this point, the big hit determination counter advances from the initial value “P”.

  As described above, each time the value of the big hit determination counter makes one round (300 counts), a new initial value is set as the count value, and thereafter the counter advances from that value. A counter for generating random 1, that is, a counter for determining the initial value of the jackpot determination counter (counter for generating random 6) is activated by a 2 ms interrupt process (periodic reset signal) executed by the CPU 56. It is counted up by the remaining time of processing. The extra time varies depending on the progress of the game, and is a random period. As a result, since the generated random 6 value is also a random value, 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 increment from a random initial value. Then, even if the illegal board is connected to the main board 31 and the big hit determination counter value update timing is recognized based on the signal output from the main board 31, the timing at which the big hit determination counter value becomes the big hit determination value is set. It becomes difficult to send an illegal start winning signal to the main board 31 in order. This is because, according to this embodiment, the timing at which the jackpot determination counter value becomes the jackpot determination value has no regularity and is random.

  In this embodiment, as is clear from the example shown in FIG. 12, the extraction timing of the random 6 used as a new initial value is not constant. Then, the randomness of the initial value of the jackpot determination counter increases, and as a result, the timing at which the jackpot determination counter value becomes the jackpot determination value becomes more random.

Embodiment 2. FIG.
In the above embodiment, the predetermined value s that determines the timing for extracting the random 6 is a predetermined value, but the predetermined value s may be variable. For example, the predetermined value s may be set based on a predetermined random number.

  FIG. 13 is an explanatory diagram showing random numbers (random 7) for determining the predetermined value s. For example, the counter for generating the random number 7 is updated in an infinite loop in the main process shown in FIG. That is, in the main process shown in FIG. 5, after step S19, a process of incrementing the counter for generating random 7 is performed. Therefore, in this embodiment, the counter for generating random 7 is not synchronized with the counter for generating random 6.

  FIG. 14 is a flowchart showing the determination random number update process (step S10) in this embodiment. The processes in steps S101 to S109 and steps S201 to S203 are the same as those in the first embodiment (embodiment 1). However, in this embodiment, when the random 1 coincides with the one-round determination value (step S107), the counter value for generating the random 7 is extracted (step S115), and the extracted value is a new predetermined value. The value s is set (step S116).

  FIG. 15 is an explanatory diagram showing an example of the value of the jackpot determination counter that is changed by the determination random number update process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. Remembered. That is, a random value of 6 is stored. In this example as well, the initial value of the predetermined value s (the value when the power is turned on) is 150.

  When the value of the big hit determination counter advances to “299” and is incremented by 1 and the value returns to 0 (steps S101, S102, S103), it is detected that the counter value matches the round determination value in the process of step S107. The Then, in the process of step S108, the stored value is set in the big hit determination counter. Further, random 7 is extracted by the processing of steps S115 and S116, and is set as a new predetermined value s. Here, it is assumed that the predetermined value s = 65.

  When the value of the big hit determination counter reaches “predetermined value s”, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the big hit determination counter reaches “19”, it is detected in step S107 that the counter value matches the round determination value. Then, in the process of step S108, the stored random 6 value is set as a new initial value in the jackpot determination counter, and “predetermined value s” is updated. Here, it is assumed that the predetermined value s = 25.

  Then, when the value of the big hit determination counter again advances to “predetermined value s”, random 6 (= P) is extracted and stored. When the value of the big hit determination counter reaches “195”, the counter value matches the round determination value. Therefore, in the processing of step S108, the stored random 6 value becomes a new initial value for the big hit determination counter. Is set. Further, a new predetermined value s is set based on the random number 7.

  In this embodiment, the timing for extracting the value (random 6) for changing the initial value of the jackpot determination counter varies further compared to the case of the first embodiment. As a result, the randomness of the initial value of the counter for generating random 1, that is, the jackpot determination counter is further increased, and the timing at which the value of the jackpot determination counter becomes the jackpot determination value becomes more random.

Embodiment 3 FIG.
In each of the above-described embodiments, the initial value is set every time the value of the jackpot determination counter makes one round. However, the initial value may be set after a predetermined round. At that time, the number of turns for setting the initial value may be variable. For example, the number of laps may be set based on a predetermined random number.

  FIG. 16 is an explanatory diagram showing a random number (random 8) for determining the number of turns n. The counter that generates random 8 is also updated by the same process as the random 1 initial value determination counter update process (steps S16 and S19) in the main process shown in FIG. That is, in the main process, it is updated at least once and is continuously updated in an infinite loop. In this example, the range that the random 8 can take is 1 to 4, but the range is arbitrary.

  FIG. 17 is a flowchart showing the determination random number update process (step S10) in this embodiment. The processes in steps S101 to S107 and steps S201 to S203 are the same as in the case of the first embodiment. However, in this embodiment, when the random number 1 coincides with the one-round determination value (step S107), the value of the number-of-turns counter is incremented by one (step S125). When the value of the lap number counter coincides with the lap number n (step S126), the processes after step S108 are executed. The number-of-turns counter is a counter that counts the number of turns of the big hit determination counter. When the power is turned on, for example, “1” is set as the number of laps n. The lap counter is cleared to 0 when the power is turned on.

  That is, when the value of the lap number counter coincides with the lap number n, the stored value is set as a new initial value in the big hit determination counter (step S108), and the stored value is set as the one-round determination value ( In step S109, a counter value for generating random 8 is extracted (step S121). Then, the extracted random 8 value is set as the number of laps n (step S122), and the lap number counter is cleared (step S123). Therefore, when the big hit determination counter laps n times, a new lap number n is set based on the random number 8.

  FIG. 18 is an explanatory diagram showing an example of the value of the jackpot determination counter that is changed by the determination random number update process shown in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. Remembered. That is, a random value of 6 is stored. In this example as well, the initial value of the predetermined value s (the value when the power is turned on) is 150.

  When the value of the big hit determination counter advances to “299” and is incremented by 1 and the value returns to 0 (steps S101, S102, S103), it is detected that the counter value matches the round determination value in the process of step S107. In addition, the value of the lap number counter coincides with the lap number n (assuming the lap number n = 1 when the power is turned on). Then, in the process of step S108, the stored value is set in the big hit determination counter. In addition, random 8 is extracted in the processes of steps S121 and S122, and is set as a new number of times n.

  Thereafter, when the value of the jackpot determination counter reaches n rounds, the stored value is set in the jackpot determination counter in the process of step S108. In addition, random 8 is extracted in the processes of steps S121 and S122, and is set as a new number of times n. Here, it is assumed that the stored value is “195”.

  Then, when the value of the big hit determination counter again advances to “predetermined value s”, random 6 (= P) is extracted and stored. Thereafter, when the value of the jackpot determination counter reaches n rounds, the stored value is set in the jackpot determination counter in the process of step S108. In addition, random 8 is extracted in the processes of steps S121 and S122, and is set as a new number of times n.

  As described above, in this embodiment, the initial value of the big hit determination counter is not set every time the counter value makes one round, but is set when the counter value has n rounds. Also, the value of n is not constant. Therefore, it is more difficult to externally predict the timing at which the value of the jackpot determination counter matches the jackpot determination value.

  It should be noted that the initial value is updated when the value of the big hit determination counter is n times as in this embodiment, and the random 6 is extracted as in the second embodiment (embodiment 2). You may use together with the form which makes predetermined value s which determines a timing variable.

Embodiment 4 FIG.
In each of the above-described embodiments, the random 6 value extracted when the value of the jackpot determination counter reaches the predetermined value s is used as the initial value of the jackpot determination counter as it is. However, some calculation may be performed on the extracted random 6 value, and the calculation result may be used as the initial value.

  FIG. 19 is a flowchart showing the determination random number update process (step S10) in the case where the result obtained by performing the addition operation on the extracted random 6 is used as the initial value. The processes in steps S101 to S107 and steps S201 to S203 are the same as in the case of the first embodiment.

  In this embodiment, when the value of the big hit determination counter coincides with the round determination value in step S107, the CPU 56 extracts a random value 6 again (step S130). Then, the extracted value and the stored value here are added (step S131). Next, the addition result is set in the jackpot determination counter as an initial value (step S132). When the added value becomes 300 or more, a value obtained by subtracting 300 is set.

  FIG. 20 is an explanatory diagram illustrating an example of the value of the jackpot determination counter that is changed by the determination random number update process illustrated in FIG. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s”. Remembered. That is, a random value of 6 is stored. In this example, the predetermined value s is 150.

  When the value of the big hit determination counter advances to “299” and is incremented by 1 to return to 0, it is detected that the counter value matches the round determination value. Then, a random value of 6 is extracted in the process of step S130. Here, it is assumed that the extracted value is “125”. The stored value is “19”. Therefore, the added value “144” of the stored value and the extracted value is set in the jackpot determination counter. Therefore, from this point, the big hit determination counter advances from the initial value “144”.

  When the value of the big hit determination counter again reaches “predetermined value s”, random 6 is extracted and stored. Here, it is assumed that the extracted value is “195”. When the value of the big hit determination counter becomes “144”, it is detected that the counter value matches the round determination value. Then, a random value of 6 is extracted in the process of step S130. Here, it is assumed that the extracted value is “186”. The stored value is “195”. Therefore, although the added value of the stored value and the extracted value is “381”, the range that can be taken by random 1 is 0 to 299. Therefore, “81” obtained by subtracting “300” is set as the jackpot determination counter. The Therefore, from this point, the big hit determination counter advances from the initial value “81”.

  Then, when the value of the jackpot determination counter again advances to “predetermined value s”, random 6 (= P) is extracted and stored. When the value of the jackpot determination counter reaches “81”, the counter value coincides with the one-round determination value. Therefore, the stored value and the extracted value are added, and the addition result “P” becomes a new initial value in the jackpot determination counter. Set as Therefore, from this point, the big hit determination counter advances from the initial value “P”.

  As described above, in this embodiment, since each random 6 value extracted at a plurality of timings is subjected to addition processing to obtain the initial value of the jackpot determination counter, the initial value undergoes a complicated process. It will be decided. Accordingly, it is still more difficult to predict the timing at which the value of the jackpot determination counter coincides with the jackpot determination value.

  In this embodiment, addition processing is used as calculation processing, but the calculation is not limited to addition. Subtraction or multiplication may be used, and any other calculation can be used. In addition, the initial value is updated when the value of the jackpot determination counter is n times as in the third embodiment, or the predetermined timing for determining the random 6 is extracted as in the second embodiment. A form in which the value s is variable may be used in combination.

Embodiment 5 FIG.
In each of the above-described embodiments, the random 6 value is extracted while the value of the big hit determination counter makes one round. However, the random 6 value may be extracted when the count makes a predetermined round. Further, the number of counts for setting the initial value may be variable. FIG. 21 is a flowchart showing the determination random number update process (step S10) in the fifth embodiment. In this example, a random 6 value is extracted when the big hit determination counter makes n turns, and an initial value is set in the big hit determination counter when the big hit determination counter makes m turns.

  The processing in steps S101 to S109 and steps S201 to S203 is the same as in the first embodiment, but in this embodiment, it is determined whether or not the value of the jackpot determination counter is a predetermined value s. (Step S104) is executed only when the value of the circulation counter is a multiple of n (Step S140).

  Accordingly, when it is detected in step S107 that the value of the big hit determination counter has made one round, the value of the number of rounds counter is incremented by one (step S141). Only when the value of the circulation counter is m, the initial value update process of steps S108 and S109 is executed (step S142).

  FIG. 22 is an explanatory diagram illustrating an example of the value of the jackpot determination counter that is changed by the determination random number update process illustrated in FIG. As shown in FIG. 21, when the count of the big hit determination counter enters the nth lap, the determination in step S140 becomes “Yes”, and a random 6 value is obtained when the counter value advances to “predetermined value s”. Is extracted and stored. In this example, the predetermined value s is 150, but the value can be arbitrarily set.

  Then, when the value of the big hit determination counter advances to “299” and is incremented by 1 on the mth round of the count of the big hit determination counter, the determination in steps S107 and S142 is “Yes”. Then, in the process of step S108, the stored value is set in the big hit determination counter. At the same time, the stored value is also set as the one-round determination value (step S109). In the example shown in FIG. 22, the stored value at this time is “195”. Therefore, from this time, the big hit determination counter advances from the initial value “195”.

  When the big hit determination counter again advances n rounds to “predetermined value s”, random 6 is extracted and stored. Here, it is assumed that the extracted value is “P”. When the value of the big hit determination counter reaches “195” on the m-th round of the count of the big hit determination counter, the stored random value “P” is set as a new initial value in the big hit determination counter. The Therefore, from this point, the big hit determination counter advances from the initial value “P”.

  As described above, in this embodiment, the extraction of the random 6 that is the initial value of the jackpot determination counter and the setting of the initial value are executed when the count of the jackpot determination counter is a predetermined number of times. Further, it is preferable that the predetermined circumference relating to the random 6 extraction and the predetermined circumference relating to the setting of the initial value are different. In this way, even if random 6 is extracted and the initial value is set at the jumping timing, the initial value of the big hit determination counter changes randomly, so that the value of the big hit determination counter is externally changed It becomes difficult to predict the timing that coincides with the determination value. In this embodiment, the extraction timing of the random 6 and the setting timing of the initial value can be set apart from each other as compared with the case of each of the above embodiments.

  In this embodiment, n and m are fixed values, but they may be variable values. For example, a random number corresponding to each may be extracted and changed according to the extracted random value. In that case, since the timing of random 6 extraction and initial value setting further varies, it is more difficult to predict the timing at which the value of the jackpot determination counter matches the jackpot determination value.

Embodiment 6 FIG.
In the fourth embodiment (Embodiment 4) shown in FIG. 19 and FIG. 20, a predetermined value is stored in one random 6 stored value and a random 6 extracted value when the big hit determination counter makes one round. Although the calculation process is performed and the calculation result is set as the initial value of the jackpot determination counter, a plurality of stored values may be used.

  FIG. 23 is an explanatory diagram showing an example of a change in the value of the jackpot determination counter when two stored values are used. In this example, two predetermined values s1 and s2 for determining the timing for extracting the random 6 are used, which are set to “150” and “250” respectively determined in advance. Since the big hit determination counter is cleared to 0 when the power is turned on, the value of the random 1 initial value determination counter (counter for generating random 6) is extracted when the counter value advances to “predetermined value s1”. Remembered. Further, when the counter value advances to “predetermined value s2”, the value of the random 1 initial value determination counter is extracted and stored.

  When the value of the big hit determination counter advances to “299” and is incremented by 1 to return to 0, it is detected that the counter value matches the round determination value. Here, the value of random 6 is extracted again. Here, it is assumed that the extracted value is “125”. The stored values are “19” and “151”. Therefore, the addition value “295” of the stored value and the extracted value is set in the jackpot determination counter. Therefore, from this point, the big hit determination counter advances from the initial value “295”.

  When the value of the big hit determination counter again proceeds to “predetermined value s1”, random 6 is extracted and stored. Here, it is assumed that the stored value is “195”. Further, when the counter value advances to “predetermined value s2”, the value of the random 1 initial value determination counter is extracted and stored. Assume that the stored value is “145”. When the value of the big hit determination counter reaches “295”, it is detected that the counter value matches the round determination value. Then, a random value of 6 is extracted. Here, it is assumed that the extracted value is “186”. The stored values are “195” and “145”. Therefore, the sum of the stored value and the extracted value is “526”, but the range that can be taken by random 1 is 0 to 299. Therefore, “226” obtained by subtracting “300” is set in the jackpot determination counter. The Therefore, from this point, the big hit determination counter advances from the initial value “226”.

  When the value of the big hit determination counter again advances to “predetermined value s1” and “predetermined value s2”, random 6 (= P2, P1) is extracted and stored. When the value of the jackpot determination counter reaches “226”, the counter value matches the round determination value. Therefore, the stored value and the extracted value are added, and the addition result “R” becomes a new initial value in the jackpot determination counter. Set as Therefore, from this point of time, the jackpot determination counter advances from the initial value “R”.

  As described above, in this embodiment, the random value extracted at three timings is added to obtain the initial value of the jackpot determination counter, so that the initial value undergoes a complicated process. It will be decided. Therefore, it becomes more difficult to predict the timing at which the value of the jackpot determination counter matches the jackpot determination value.

  In this embodiment, addition processing is used as calculation processing, but the calculation is not limited to addition. Subtraction or multiplication may be used, and any other calculation can be used. Further, a configuration in which the initial value is updated when the value of the jackpot determination counter n times as in the third embodiment may be used together.

Embodiment 7 FIG.
In the above-described embodiment, the predetermined values s1 and s2 for determining the timing for extracting the random 6 are fixed values set in advance, but the predetermined values s1 and s2 may be variable. FIG. 24 is an explanatory diagram showing an example of a change in the value of the big hit determination counter when the predetermined values s1 and s2 are set to “20” and “200” in the nth round of the count of the big hit determination counter.

  As shown in FIG. 24, the same processing as in the sixth embodiment (sixth embodiment) is performed from the first round to the (n-1) th round of the count of the big hit determination counter. In the n-th round, when the value of the big hit determination counter advances to “predetermined value s1 = 20” and “predetermined value s2 = 200”, random 6 (= P1, P2) is extracted and stored. If the count of the n-th cycle starts from “S”, when the value of the jackpot determination counter becomes “S” again, a random value of 6 is extracted, and the extracted value and the stored values P1, P2 and The calculation result T is set as the initial value T in the jackpot determination counter.

  In this case, in the form in which arithmetic processing is performed on each value of random 6 extracted at three timings to obtain the initial value of the jackpot determination counter, the random number 6 is counted in a specific round of the count of the jackpot determination counter. Therefore, the initial value goes through a more complicated calculation process, and the initial value of the jackpot determination counter becomes more random.

  In this embodiment, n is a fixed value, but n may be a variable value corresponding to a random number, for example. Further, the number of random 6 extractions may be changed in a specific round of the count of the big hit determination counter. That is, the number of stored values may be changed.

  As described above, in each of the above embodiments, the random number 6 is extracted and stored when the count value of the jackpot determination counter reaches a predetermined value, and stored when the count of the jackpot determination counter circulates a predetermined number of times. A value of 6 is set as an initial value in the big hit determination counter. Therefore, for example, as shown in FIG. 12, the extraction timing of the random 6 used as a new initial value is not constant. Then, the randomness of the initial value of the counter for generating random 1, that is, the jackpot determination counter increases, and as a result, the timing at which the jackpot determination counter value becomes the jackpot determination value becomes more random and difficult to predict from the outside. It will be a thing.

  Note that in the gaming machines of the above-described embodiments, that is, the pachinko gaming machine shown in the front view of FIG. 1, a special symbol that is variably displayed on the variable display unit 9 based on the start winning prize has a predetermined symbol. The first type pachinko gaming machine that can be given a predetermined game value to a player when it is a combination of the above, but if there is a prize in a predetermined area of the electric game that is released based on the start prize, the predetermined game value If there is a prize for a type 2 pachinko gaming machine that can be given to a player, or a predetermined electric combination that is released when a combination of a predetermined symbol that is variably displayed based on the start prize is a combination of the predetermined symbols The present invention can also be applied to a third type pachinko gaming machine in which predetermined rights are generated or continue.

  Further, any means for realizing the variable display unit 9 may be used. For example, the variable display unit 9 may be realized by a display such as a CRT or LED, or a drum-type or belt-type variable display device may be used.

  Further, in each of the above embodiments, the main process shown in FIG. 5 is started by a periodic reset signal given from the outside of the CPU 56, but without using the periodic reset signal, for example, an internal timer interrupt of the CPU 56, etc. The present invention can also be applied to the case where the main process is executed.

  Note that the gaming machine may further include an initial setting timing determining means for determining a predetermined number of times as a condition for setting an initial value in the specific game determination counter. In a case where an initial setting timing determining means for determining a predetermined number of rounds that is a condition for setting an initial value in the specific game determination counter is provided, the initial value setting timing varies more in time, so that the specific game There is an effect that it is more difficult to externally estimate the timing at which the numerical value for determination matches the determination value.

  Further, the initial setting timing determining means may be configured to update a numerical value for determining a predetermined number of rounds in an infinite loop. When the numerical value for determining the predetermined number of laps is configured to be updated in an infinite loop, the variation in the initial value setting timing becomes larger and the specific game determination numerical value matches the determination value This has the effect of making it more difficult to guess outside.
