On the other hand, when the determination result is a jackpot and the jackpot symbol random number is any one of “0”, “2”, “4”, “6”, “8”, “10”, that is, the display The combinations of jackpot symbols that are stopped and displayed on the device 10 are “0, 0, 0”, “2, 2, 2”, “4, 4, 4”, “6, 6, 6”, “8, 8, 8”. ”And“ 10, 10, 10 ”, a low probability state (normal state) is obtained in the case of an even number of combinations (even numbers).

  The reach random number counter is used for determining whether or not a reach state is reached when the jackpot determination result based on the jackpot random number value is out of reach, and is a random number of “0” to “126”. Consists of. The reach state in the present embodiment is other than the special symbol (for example, the middle special symbol) that is stopped and displayed last among the left special symbol, the middle special symbol, and the right special symbol that are displayed on the display device 10 in a variable stop state. Special symbols (for example, left special symbol and right special symbol) are the same (excluding the final stop symbol, the state is equal to the jackpot special symbol combination, and finally the jackpot special symbol combination is off State including the case of a special symbol combination). The random number of the reach random number counter (reach random number) starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every time a normal symbol / special symbol main random number update process described later is performed. Then, it is set to “0” and the addition is repeated again. The reach random number is acquired due to winning in the upper start winning opening 41 or the lower start winning opening 42, and when the result of the determination is wrong, the numerical value is compared with a predetermined reach establishment value. The reach is determined. In this embodiment, reach establishment values are “5”, “17”, “28”, “40”, “51”, “63”, “74”, “86”, “97”, “109”, “ 120 '.

  The special symbol data random number counter is used for determining a special symbol combination that is to be stopped and displayed on the display device 10 when the jackpot determination result based on the jackpot random number value is out of order. A random number counter for special symbol data 1 for determining the left special symbol to be stopped, a random number counter for special symbol data 2 for determining the middle special symbol, and a random number counter for special symbol data 3 for determining the right special symbol; Each special symbol data random number counter is composed of random numbers from “0” to “11”.

The random number of the special symbol data 1 starts from “0” when the power is turned on and is incremented by “1” every time the normal symbol / special symbol main random number update process described later is performed. The above addition is repeated again. The random number of the special symbol data 2 starts from “0” when the power is turned on, and is incremented by “1” when the random number of the special symbol data 1 is rewritten to “0”, and reaches “11”. Then, it is rewritten to “0” and the addition is repeated again. Further, the random number of the special symbol data 3 starts from “0” when the power is turned on, and is incremented by “1” when the random number of the special symbol data 2 is rewritten to “0”, and reaches “11”. Then, it is rewritten to “0” and the addition is repeated again.

  Each random number of the special symbol data 1 to 3 is 0 if it is “0”, “1” if it is “1”, “2” if it is “2”, etc. A special symbol that is sometimes stopped and displayed on the display device 10 is assigned. The random numbers of the special symbol data 1 to 3 are acquired due to winning in the upper starting winning port 41 or the lower starting winning port 42, and when the special symbol data 1 to 3 are combined, The off symbol combination consisting of the left special symbol, middle special symbol, and right special symbol displayed on the display device 10 is determined.

  The variation mode random number counter is used when the variation mode of the special symbol in the display device 10 is selected from a plurality of variation modes, and includes a variation mode random number of ‘0’ to ‘198’. When the gaming machine 1 is turned on, the fluctuation mode random number value starts from “0” and is incremented by 1 for each of the normal symbol / special symbol main random number update processing to be described later. It is set to “0” and the addition is repeated again. The variation mode random value is acquired due to winning in the upper start winning opening 41 or the lower start winning opening 42.

  A range of variation mode random values is set for each variation mode, and a variation mode corresponding to the acquired variation mode random value is selected. A variation time is set for each variation mode, and a special symbol variation / stop display mode (including a special symbol variation time) displayed on the display device 10 according to the set variation time and a special symbol A variation effect mode such as a background, a character, or a character to be displayed during or after the change is determined.

  Regarding the acquired jackpot random number value, jackpot symbol random number value, reach random number value, and variation mode random number value, a maximum of four, respectively, the number of the special symbol hold (establishment of the judgment condition) in the corresponding area in the RAM of the main control board 200 Are stored in the order of winning (in the order of determination criteria), and are read out and used sequentially.

The normal symbol random number counter is used to determine a normal symbol per unit, and has a normal symbol random number of “0” to “299”. When the gaming machine 1 is turned on, it starts from “0” and will be described later. Each time the special symbol main random number update process is incremented, “1” is added, and when it reaches “299”, it is rewritten to “0” and the addition is repeated again. The normal symbol random numbers are acquired every time the game balls that have passed through the normal symbol variation start gate 55 are detected by the gate detection switch, and up to four normal symbol random number storage areas in the RAM of the main control board 200. Stored in The value of the normal symbol random number acquired due to the passing of the game ball through the normal symbol variation start gate 55 is set to “5” (1/300) as the established value per normal symbol in the low probability state. If it matches the probability of “0” to “59” (1/5) set as a numerical value established per normal symbol in the probability variation (high probability) state, Usually per symbol. In the case of per ordinary symbol, “O” is displayed on the ordinary symbol display device 50, and the lower start winning opening 42 is opened for the open time. On the other hand, the value of the obtained ordinary symbol random number matches the established value per ordinary symbol. If not, the symbol is out of the normal symbol and “x” is displayed on the normal symbol display device 50, and the lower start winning opening 42 is left in a state where it is difficult to win.

  The game of the gaming machine 1 will be briefly described. In the gaming machine 1, when the game balls launched by the launch device 64 toward the game area 6 win the various winning holes, a predetermined number of gaming balls corresponding to the winning holes are awarded as the winning balls from the payout device 281. The upper ball receiving tray 36 is paid out. Further, when the game ball passes through the normal symbol variation start gate 55, a normal symbol random number is acquired, and the normal symbol display device 50 determines the normal symbol per unit based on the acquired random number value. Starts to fluctuate and stops after fluctuating for a predetermined time. At that time, if the determination result per normal symbol is a win, it stops at the normal symbol, “◯” in this example, and the two movable pieces 42a and 42b of the lower start winning port 42 are on the back side. The closed solenoid (normal state), which is almost vertical and difficult to win, is changed from the closed solenoid (normal state) to the open state in which a winning is possible with a V shape (reverse C shape). When a game ball wins the lower start winning opening 42, a predetermined number of game balls are paid out as a prize ball.

  Further, when a game ball wins in the upper start winning opening 41 or the lower start winning opening 42, if the number of special symbol hold is less than 4, the special symbol hold number is incremented by 1, and the jackpot random number value or jackpot symbol disorder Random numbers such as numerical values, reach random numbers, fluctuation mode random numbers, etc. are acquired and stored in the RAM of the main control board 200 in the order of winning until the maximum is 4. And if the number of special symbol reservations memorize | stored in RAM of the said main control board 200 is one or more, while determining the success or failure of jackpot based on the jackpot random value acquired previously, based on the fluctuation mode random value One variation mode is selected from a plurality of variation modes. Based on the selected variation mode, the display device 10 starts the variation display of the special symbol. In the present embodiment, the special symbol hold count is subtracted from the RAM of the main control board 200 by the start of the change of the special symbol, and the random value corresponding to the start of change is deleted (erased) from the RAM of the main control board 200. Is done. If the number of special symbol reservations stored in the RAM of the main control board 200 is 0, then the game ball wins the upper start winning opening 41 or the lower start winning opening 42, and the main control Until the number of special symbol reservations stored in the RAM of the substrate 200 becomes 1 or more, the determination of whether or not the symbol is determined and the special symbol is not displayed.

  The special symbol is stopped and displayed on the display device 10 with the passage of the variation time set in the selected variation mode (end of the variation time). When the game success / failure determination result is out of place, the display device 10 stops the left special symbol, middle special symbol, and right special symbol in a combination (in a state other than a slotted pattern) and stops in a special game (big hit game). There is no migration. If the number of special symbol reservations stored in the RAM of the main control board 200 is 1 or more, the jackpot random number value or the like is acquired again in the same manner as described above, and whether or not the jackpot is determined based on the acquired jackpot random number value While the determination is made, one variation mode is selected from a plurality of variation modes based on the determination result and the variation mode random value, and the display device 10 includes a variation display of a special symbol based on the selected variation mode. Production is performed.

  On the other hand, when the determination result is a big hit, the left special symbol, the middle special symbol, and the right special symbol are stopped on the display device 10 in combination with the big hit symbol (in the present embodiment, a glance). At that time, in the case of the normal jackpot, a normal jackpot symbol (ordinary jackpot determination symbol) consisting of an even number of eyes such as “2, 2, 2” is displayed on the display device 10, and then a special game ( It becomes a jackpot game) state. On the other hand, in the case of a probabilistic jackpot, a probable jackpot symbol (special jackpot judgment symbol) consisting of odd numbers such as “1, 1, 1” is displayed on the display device 10, and then a special game (bonus game) ) State.

  In a special game (big win game) state, the open / close plate 46 of the big prize opening 45 is opened to make it easier to receive the game balls falling on the surface of the game area 6 so that the big prize opening 45 can be awarded, When there is a winning at the big winning opening 45, a predetermined number of game balls are paid out as winning balls. The opening / closing plate 46 is closed after a predetermined time (for example, 29.5 seconds) has elapsed or when the number of winning balls reaches a predetermined number (for example, 10). The opening of the opening / closing plate 46 is repeated for a predetermined number of rounds (for example, 15 rounds).

  In the case of a normal jackpot, the probability of the next jackpot is set to a low probability after the end of the special game (jackpot game). On the other hand, in the case of a probabilistic jackpot, the probability of the next jackpot is set to a high probability after the end of the special game (jackpot game).

  Further, in this embodiment, when there is no detection of magnetism by the magnetic sensor 81 and vibration detection by the vibration sensor 83, the number of special symbol reservations for winning a prize opening as described above. Addition, random number acquisition, determination of success / failure, and game ball payout (prize ball payout), etc., but when at least one of magnetic detection by the magnetic sensor 81 or vibration detection by the vibration sensor 83 is detected. Since the winning signal is not transmitted to the CPU 201 even if a game ball wins a winning opening such as the upper start winning opening 41 or the like, the special symbol holding number is not added or a random number is not acquired, and the gaming ball for winning is not received. There is no payout.

  The control process in the gaming machine 1 will be described below. In the main control board 200, the CPU performs a main process M in accordance with a control program (main control procedure) stored in the ROM. FIG. 8 is a flowchart of the main process M.

  In the main process M, an initial setting process (S10) such as a CPU, an interrupt prohibition process (S20), a normal symbol / special symbol main random number update process (S30), an interrupt permission process (S40) are performed, and a loop process is performed in the final process. Is being performed, interrupt processing (S100) is executed every 2 ms.

  In the initial setting process (S10) of the CPU and the like, stack setting, interrupt time setting, CPU setting, SIO, PIO, CTC setting and the like are performed. Although the main process M is repeatedly performed, the initial setting process (S10) of the CPU or the like is an initial control procedure necessary only when the power is turned on, and is executed only in the first round, and is not executed thereafter. Details are omitted because they are well known.

In the interrupt prohibition process (S20), even if the interrupt process (S100) is entered every 2 msec, the interrupt is prohibited until the interrupt is permitted.
In the normal symbol / special symbol main random number update process (S30), various random numbers are added for each of the normal symbol / special symbol main random number update process (S30), and when the update range upper limit value of each random number is reached as described above, The value is returned to the minimum value and the addition is performed again. The updated random number is stored in the RAM of the main control board 200.
In the interrupt permission process (S40), the interrupt process (S100) that enters every 2 msec is permitted.

  In the interrupt process (S100), as shown in FIG. 9, the output process (S101), the input process (S102), the normal symbol / special symbol main random number update process (S103), the winning detection process (S104), the normal operation process ( S105), special operation processing (S106), number-of-holds processing (S107), and other processing (S108) are performed in order.

  In the output process (S101), if there is an output command (command signal) set in each process, an output command (command signal) is transmitted to each control board.

  In the input process (S102), a permission signal for permitting processing by the buffer IC 202 is output to the buffer IC 202, input to an enable terminal G1 (a permission signal receiving unit) of the buffer IC 202, and attached to the gaming machine 1. Signals when various sensors (switches) are detected are input, and a winning signal from the buffer IC 202 is input to the CPU 201. As described above, in a state where both the permission signal and the detection signal are received by the buffer IC 202, even if the buffer IC 202 receives a winning detection signal for the winning opening, On the other hand, in the state where the buffer IC 202 has received the permission signal and has not received the detection signals from the magnetic sensor 81 and the vibration sensor 83, the winning detection signal to the winning opening is not output to the CPU 201. When received by the buffer IC 202, the winning signal is output from the buffer IC 202 to the CPU 201. In addition, since the permission signal in this embodiment is output at the timing of the input process (S102), it is output every predetermined time (2 ms) when the interrupt process (S100) is executed.

  In the normal symbol / special symbol main random number update process (S103), the same process as the normal symbol / special symbol main random number update process (S30) performed in the loop process in the main process M is performed.

  In the winning detection process (S104), as shown in FIG. 10, it is first determined whether a winning signal is received from the buffer IC 202 in the input process (S102) (S104-1). If no winning signal has been received, that is, if no winning prize has been received in the winning slot, or if no winning signal is output from the buffer IC 202 even if winning has been detected and magnetism or vibration has been detected, the winning prize is received as it is. The detection process ends. On the other hand, when the winning signal is received, that is, when the winning prize is won and no magnetism or vibration is detected, the winning prize is the starting winning prize (upper starting prize 41 or lower starting prize). Mouth 42) or (S104-2), the normal symbol variation start gate 55 (S104-3), or the winning to another winning mouth (S104-4) is confirmed in order.

  If the winning is a starting winning port (upper starting winning port 41 or lower starting winning port 42), it is determined whether the number of special symbol reservations is 4 or more (S104-5). The winning command signal corresponding to the winning is stored in the output buffer (S104-8), and the winning detection process (S104) is completed. On the other hand, if the number of special symbol reservations is less than 4, the special symbol reservation number is incremented by 1 (S104-6), and special symbol related random numbers such as jackpot random number value, jackpot symbol random number value, reach random number value, variation mode random number value, etc. Is acquired and stored in the corresponding area of the RAM of the main control board 200 (S104-7), and then a winning command signal corresponding to the winning of the start winning opening is stored in the output buffer. (S104-8), and the winning detection process (S104) ends. The winning command signal stored in the output buffer is output to the payout control board (second control device) 240 and the sub control board 205 in the output process (S101).

  When the winning is the normal symbol variation start gate 55 (when the game ball passes through the normal symbol variation start gate 55), it is determined whether or not the number of normal symbol reservations is 4 or more (S104-9), 4 In the above case, the winning detection process (S104) ends. On the other hand, if the number of retained ordinary symbols is less than 4, the number of retained ordinary symbols is incremented by 1 (S104-10), the ordinary symbol random number value is acquired, and the acquired ordinary symbol random number value corresponds to the RAM in the main control board 200. (S104-11), and then the winning detection process (S104) ends. The winning command signal stored in the output buffer is output to the sub-control board 205 in the output process (S101).

  When the winning is other winning opening (left sleeve winning opening 52, left dropping winning opening 53, right dropping winning opening 54), a winning command signal corresponding to winning winning is stored in the output buffer (S104-12). ), The winning detection process (S104) ends. The winning command signal stored in the output buffer is then output to the payout control board (second control device) 240 in the output process (S101). If no prize has been won, the prize detection process (S104) is terminated.

  In the normal operation process (S105), when the number of normal symbol hold is not 0, it is acquired in the normal symbol random number acquisition process (S104-11) of the winning detection process (S104) and stored in the RAM of the main control board 200. When the acquired normal symbol random number value is read and in the low probability state, the acquired normal symbol random number value is compared with the established value per normal symbol in the low probability state, and in the case of coincidence, the normal symbol in the low probability state If it does not match, it will be considered as a miss. On the other hand, in the case of probability change (high probability state), the acquired normal symbol random number value is compared with the established value per normal symbol in the high probability state. In some cases, it is considered to be off.

  In the special operation process (S106), a jackpot determination process, a special symbol selection process, a special symbol variation mode selection process, a special symbol random number shift process, a special symbol variation start process, and a special electric accessory process are performed.

  In the jackpot determination process, the jackpot random number value acquired in the special symbol related random number acquisition process (S104-7) of the winning detection process (S104) and stored in the RAM of the main control board 200 is read out, and the low probability state In this case, the acquired jackpot random number value is compared with the jackpot value in the low probability state, and if it matches, it is determined to be a jackpot in the low probability state, and if it does not match, it is determined to be off. On the other hand, in the case of probability change (high probability state), the acquired jackpot random number value is compared with the jackpot value in the high probability state. To be judged. This jackpot determination process corresponds to a hit / fail determination means.

  In the special symbol selection process, in the case of jackpot, the special symbol based on the jackpot symbol random number is set as a stop special symbol, while in the case of losing, the special symbol data random number value (special symbol data 1 · special symbol data 2 · The special symbol data 3) is acquired, and a special symbol out of place is set as a stop special symbol based on the acquired special symbol data random value. At that time, when the random values of the acquired special symbol data 1, special symbol data 2, and special symbol data 3 match, or when the random values of special symbol data 1 and special symbol data 3 match Depending on whether or not the acquired reach random number value is a reach that matches the reach establishment value, the acquired special symbol is set so that the special symbol to be set does not become a random pattern and corresponds to the presence or absence of reach Processing such as addition is added to the design data random value.

In the special symbol variation mode selection process, the variation mode random value acquired and stored is read, and one variation mode is selected from a plurality of variation modes based on the read variation mode random value.
In the special symbol random number shift process, in the data storage area of the special symbol holding number in the RAM, the data of the special symbol holding number stored in the storage area of the address having the highest load (reading) order is loaded by the previous process. Due to the fact that the seat becomes empty, the address of the special symbol holding number stored in the second and subsequent addresses is shifted by one by one.
In the special symbol variation start process, processing necessary for starting the variation of the special symbol is performed.

  In the special electric accessory process, a process related to opening and closing of the big prize opening 45 in a special game (big hit game) is performed. Further, when 10 game balls are won in the big winning opening 45, or when a round end time (30 seconds in this embodiment) elapses, a special game (big hit game) is terminated.

In the hold number process (S107), the current hold number is loaded and the hold number is set in the output buffer.
In other processing (S108), various other processing necessary for the game is performed.

  In the present embodiment, the configuration is such that magnetism and vibration are detected as fraud detection, but it may be configured to detect radio waves. In addition, when the fraud detection means detects fraud, a configuration of fraud notification may be added in which the speaker 38 is notified or the lamp device 35 is turned on to notify the fraud detection. In that case, after the signal of the fraud detection means is input to the gate IC 204, it is divided into a signal input to the buffer IC 202 and a signal input to the sub-control board 205, and the sub-control board 205 side performs notification processing. Is preferred. With such a configuration, when there is a fraud, the main control board (main control circuit) 200 can notify the user without performing a process corresponding to the fraud. Furthermore, it is assumed that a signal after being input to the gate IC 204 may be configured to be externally output to the game store side.

  As described above, in this embodiment, even if a game ball wins or passes through the winning opening, the buffer IC receives both the permission signal from the CPU and the fraud detection signal by the fraud detection means. In this case, the winning signal is not output to the CPU. On the other hand, the winning signal is output to the CPU when only the permission signal is received by the buffer IC. Therefore, the illegal processing is performed without performing the software processing by the CPU. If it is used in combination with a configuration for notifying the detection of fraud, it is possible to deal with the fraud even if the amusement store does not notice the notification. Is possible.

  The present invention is not limited to the above-described embodiments, and can be changed without departing from the spirit of the invention.
