1. Ceiling function When the power is turned on, the game mode is set to the normal probability mode 1, and the value of the limit counter is reset. When the power is turned on, it means a case where a memory such as a RAM is initialized. At the time of initial setting, unnecessary data is cleared from the RAM and necessary data is initialized to a predetermined state. When a game ball enters the special symbol start opening device in the normal probability mode 1 setting state, it is determined with a normal probability corresponding to the normal probability mode 1 that it is a big hit. When it is determined that this is a big hit, the value of the limit counter is updated, it is determined that the game mode is set to the high probability mode 1, and the determination result of the big hit is displayed on the special symbol display. When the determination result of jackpot is displayed on the special symbol display, the jackpot game is started, and the game mode is set to the high probability mode 1 at the end of the jackpot game.

  When a game ball enters the special symbol starter device with the high probability mode 1 set, it is determined with a high probability according to the high probability mode 1 that it is a big hit. When it is determined that a big hit is made in the setting state of the high probability mode 1, the value of the limit counter is updated, the game mode determination process is performed, and the determination result of the big hit is displayed on the special symbol display. When the jackpot determination result is displayed on the special symbol display, the jackpot game is started, and the game mode is set as the determination result at the end of the jackpot game. In this high probability mode 1 setting state, the high probability mode 1 setting is determined with a higher probability than the high probability mode 2 setting, so that the game mode is re-entered with high probability mode 1 at the end of the big hit game. Is set. That is, in the high probability mode 1 setting state, the game ball enters the special symbol start opening device, so that the limit counter value updating process and the high probability mode 1 setting process are repeated with high probability.

  When the value of the limit counter reaches the limit value because it is determined to be a big hit in the setting state of the high probability mode 1, it is determined that the game mode is set to the normal probability mode 2, and the special symbol display The judgment result is displayed. When the jackpot determination result is displayed on the special symbol display, the jackpot game is started, and the game mode is set to the normal probability mode 2 at the end of the jackpot game. When it is determined that the big hit is in the set state of the normal probability mode 2, the value of the limit counter is updated, and it is determined that the game mode is set to the high probability mode 2. The value of this limit counter is reset to the initial value when it reaches the limit value at the time of the previous jackpot determination, and is updated from the initial value. When it is determined that the big hit is set in the normal probability mode 2, the big hit game is started after the big hit determination result is displayed on the special symbol display, and the game mode is set to the high probability mode at the end of the big hit game. 2 is set.

  The game mode is set to the normal probability mode 2 when the number of jackpot determination reaches the limit value based on the fact that the high probability mode 1 is set first, and is determined to be a big hit in the setting state of the normal probability mode 2 As a result, the normal probability mode 2 shifts to the high probability mode 2. The number of game balls entering the special symbol starter device required for the transition from the initial setting of the gaming mode to the high probability mode 1 to the high probability mode 2 through the normal probability mode 2 is high probability mode 1. The number of game balls that enter the game is called a ceiling value.

When the number of game balls entering the special symbol starter device does not reach the ceiling value, the game ball enters the normal symbol starter device in each of the high probability mode 1 setting state and the normal probability mode 1 setting state Since it is determined with a low probability that it is a win, the probability that a hit game is started is low. When a game ball enters the normal symbol starter device in the normal probability mode 2 setting state and the high probability mode 2 set state in which the number of game balls entering the special symbol starter device has reached the ceiling value Since it is determined with high probability that it is a win, the hit game is started with a high probability. This winning game is performed when the game ball enters the special symbol starting device and the maximum number of award balls to be paid out to the player is a big hit game, and the game ball enters the special ball opening device. It is set to a large number compared to the maximum number of prize balls to be paid out, and the player can play the game ball with a special symbol start port device until the game mode is set to the normal probability mode 2 or the high probability mode 2 A number of prize balls can be obtained by causing the normal symbol starter device to enter the game ball until it is determined that it is a winning after entering the ball. That is, the ceiling function can be set without adopting a process of increasing the jackpot determination probability when the number of consecutive determinations of deviation reaches the limit value.
2. About the continuation function of high probability mode 2 When it is determined that a big hit is made in the setting state of high probability mode 2, the value of the limit counter is updated, the determination process of the game mode is performed, and the special symbol display The judgment result is displayed. When the jackpot determination result is displayed on the special symbol display, the jackpot game is started, and the game mode is set as the determination result at the end of the jackpot game. In this high probability mode 2 setting state, the high probability mode 2 setting is determined with a higher probability than the high probability mode 1 setting, so that at the end of the big hit game, the game mode is re-entered with a high probability mode 2. Is set. That is, in the setting state of the high probability mode 2, when the game ball enters the special symbol start opening device, the update process of the limit counter value and the setting process of the high probability mode 2 are repeated with high probability. For this reason, the player's advantageous state in which the player can generate a winning game with a high probability by allowing the player to enter the game ball into the normal symbol start opening device continues.

If the setting of the high probability mode 1 is determined before the limit counter value reaches the limit value in the setting state of the high probability mode 2, the game mode is set to the high probability mode 1 at the end of the big hit game, and the limit The player's advantageous state is canceled before the counter value reaches the limit value. That is, in the high probability mode 2, the setting of the high probability mode 1 is continued until the limit counter value reaches the limit value until the determination or the limit counter value reaches the limit value. When the high probability mode 2 continues until the limit value is reached, the high probability mode 2 is changed again to the high probability mode 2 after the high probability mode 2 is changed to the normal probability mode 2. Therefore, the high probability mode 2 Will continue again.
3. Other functions When the setting of high probability mode 2 is judged before the limit counter value reaches the limit value in the setting state of high probability mode 1, the game mode is changed to high probability mode 2 at the end of the big hit game. It is set and a player advantageous state occurs before the value of the limit counter reaches the limit value. In this case, the value of the limit counter is continuously added without being reset, and when the value of the limit counter reaches the limit value while the game mode is set to the high probability mode 2, the game mode has a high probability. The mode 2 is reset to the high probability mode 2 through the normal probability mode 2. In other words, the player-favored state occurs when the limit counter value does not reach the limit value and when the limit value is reached. It becomes difficult for the player to estimate the value of the limit counter by measuring the number of game balls that have entered the special symbol starter device until that time.

The value of the counter MR4 is cleared, and in step S113, it is determined whether or not the value of the random counter MR4 is recorded in the normal symbol hold data storage unit 131 of the hold number 2. Here, when it is determined that the value of the random counter MR4 is not recorded in the normal symbol holding data storage unit 131 of the holding number 2, the process proceeds to step S119, and (2) is set in the normal symbol process flag of the flag storage unit 135. Set.

  If the CPU 61 determines that the value of the random counter MR4 is recorded in the normal symbol holding data storage unit 131 with the holding number 2 in step S113, it is recorded in the normal symbol holding data storage unit 131 with the holding number 2 in step S114. The value of the random counter MR4 is shifted to the normal symbol hold data storage unit 131 with the hold number 1. In step S115, it is determined whether or not the value of the random counter MR4 is recorded in the normal symbol holding data storage unit 131 of the holding number 3, and the value of the random counter MR4 is stored in the normal symbol holding data storage unit 131 of the holding number 3. Is determined not to be recorded, (2) is set to the normal symbol process flag in the flag storage unit 135 in step S119.

[2-5-3] Normal Symbol Fluctuation Stop Process FIG. 31 shows the normal symbol fluctuation stop process in step S83. This normal symbol fluctuation stop process is executed when the normal symbol process flag of the flag storage unit 135 is set to (2), and the CPU 61 performs on / off control of the LED of the normal symbol display 35 in step S121. By doing so, the normal symbol is displayed in a varying manner alternately between the winning symbol (◯) and the off symbol (×). In step S122, the remaining time of the normal symbol game is updated by subtracting a predetermined unit value (4 msec) previously recorded in the ROM 62 from the timer MT1 of the timer storage unit 136. In step S123, the timer of the timer storage unit 136 is updated. The subtraction result of MT1 is compared with the limit value (0) recorded in advance in the ROM 62.

  If the CPU 61 determines that “MT1 = 0” in step S123, the CPU 61 stops the normal symbol variation display on the normal symbol display 35 in step S124. The stop display of the normal symbol is performed based on the setting result of the normal symbol recorded in the normal symbol storage unit 133. When it is determined that the symbol is a win, the normal symbol variation display is a win symbol (○ ), And if it is determined that it is out of place, the change display of the normal symbol is out and stops at the symbol (×).

When the CPU 61 stops the normal symbol fluctuation display in step S124, the normal symbol setting result is cleared from the normal symbol storage unit 133 in step S125. In step S126, a predetermined interval time (1.0 × 1000 msec) recorded in advance in the ROM 62 is set in the timer MT1 of the timer storage unit 136. In step S127, the normal symbol process flag in the flag storage unit 135 is set to (3). Set.

If it is determined that the hit flag of the flag storage unit 135 is set to the off state, the process proceeds to step S134, and (0) is set to the normal symbol process flag of the flag storage unit 135. In a state where the normal symbol process flag is set to (0), the next normal symbol process process proceeds to a hit determination process in step S81, and the value of the random counter MR4 is stored in the normal symbol hold data storage unit 131 of the hold number 1. Whether or not it is a hit when it is recorded is determined by a hit probability according to the set state of the game mode.

  If the CPU 61 determines in step S133 that the hit flag of the flag storage unit 135 is set to the on state, the CPU 61 sets the hit flag of the flag storage unit 135 to the off state in step S135, and the counter of the counter storage unit 137 in step S136. A limit number (10) is set in MN2, and a limit time (5.9 × 1000 msec) is set in timer MT1 of timer storage unit 136 in step S137. Each of the limit number and the limit time is recorded in advance in the ROM 62, and the limit number corresponds to the maximum number of game balls allowed to win in the lower special symbol start port 27 in the hit game. The time corresponds to the maximum time allowed to keep the lower special symbol start opening 27 in the open game.

When the CPU 61 initially sets the timer MT1 of the timer storage unit 136 in step S137, it sends a game start command (B000h) to the effect control circuit 90 in step S138 to notify that the winning game starts.

If it is determined that “MT1 = 0”, the process proceeds to step S146, and the special symbol start port solenoid 31 is turned off to return the lower special symbol start port 27 from the open state to the closed state.

  If the CPU 61 determines that “MT1> 0” in step S142, it determines whether or not a special symbol start signal is output from the special symbol start port sensor 30 in step S143. If it is determined that the special symbol start signal is output from the special symbol start port sensor 30, the process proceeds to step S144, and a predetermined unit value (1) recorded in advance in the ROM 62 from the counter MN2 of the counter storage unit 137. ) Is subtracted to update the remaining limit number, and the process proceeds to step S145.

  In step S145, the CPU 61 compares the subtraction result of the counter MN2 in the counter storage unit 137 with the limit value (0). If it is determined that “MN2 = 0”, the process proceeds to step S146 to return the lower special symbol start port 27 from the open state to the closed state. That is, the lower special symbol start port 27 reaches the limit time (5.9 × 1000 msec) when the limit number (10) of game balls wins in the lower special symbol start port 27 or the lower special symbol start port 27 opens. It will be closed.

When the CPU 61 returns the lower special symbol opening 27 from the open state to the closed state in step S146, the CPU 61 notifies the effect control circuit 90 in step S147 that the game stop command B100h is transmitted to notify that the winning game is ended. In S148, (0) is set to the normal symbol process flag in the flag storage unit 135.

This special symbol variation process is executed when the special symbol process flag of the flag storage unit 135 is set to (2), and the CPU 61 performs on / off control of the LED of the special symbol display 46 in step S221. Thus, the special symbol display 46 displays the special symbol in a fluctuating state, and the remaining time of the special symbol game is updated by subtracting the unit value (4 msec) from the timer MT2 of the timer storage unit 136 in step S222. In step S223, the result of subtraction of the timer MT2 in the timer storage unit 136 is compared with the limit value (0). If it is determined that “MT2 = 0”, the change control command 8100h is sent to the effect control circuit 90 in step S224. In step S225, (3) is set in the special symbol process flag of the flag storage unit 135.
[2-6-4] Special symbol fluctuation stop process FIG. 39 shows the special symbol fluctuation stop process in step S154. This special symbol variation stop process is executed when the special symbol process flag of the flag storage unit 135 is set to (3), and the CPU 61 changes the special symbol change of the special symbol display 46 in step S231. Stop display. This special symbol stop display is performed based on the setting result of the special symbol in the special symbol storage unit 134. When the low probability winning symbol 1 (1) is recorded in the special symbol storage unit 134, the special symbol is displayed. When the fluctuation display stops at the low probability winning symbol 1 (1) and the low probability winning symbol 2 (2) is recorded in the special symbol storing unit 134, the variation display of the special symbol becomes the low probability winning symbol 2 (2 ) And when the probability variation big hit symbol 1 (3) is recorded in the special symbol storage unit 134, the special symbol variation display stops at the probability variation big hit symbol 1 (3) and the special symbol storage unit 134 When the jackpot symbol 2 (4) is recorded, the special symbol variation display stops at the probability variation jackpot symbol 2 (4), and when the symbol symbol (5) is recorded in the special symbol storage unit 134. The special symbol change display is off and stops at symbol (5). That.

When the CPU 61 finishes displaying the special symbols in step S231, the CPU 61 sets the interval time (1.0 × 1000 msec) recorded in advance in the ROM 62 in the timer MT2 of the timer storage unit 136 in step S232, and the flag storage unit in step S233. (4) is set in the 135 special symbol process flag.
[2-6-5] Interval Processing FIG. 40 shows the interval processing in step S155. This interval process is executed when the special symbol process flag of the flag storage unit 135 is set to (4), and the CPU 61 obtains a unit value (4 msec) from the timer MT2 of the timer storage unit 136 in step S241. The remaining interval time is updated by subtraction. In step S242, the result of subtraction of the timer MT2 in the timer storage unit 136 is compared with the limit value (0). If it is determined that “MT2 = 0”, the process proceeds to step S243.

  When proceeding to step S243, the CPU 61 determines whether or not the big hit flag of the flag storage unit 135 is set to the on state. If it is determined that the big hit flag of the flag storage unit 135 is set to the off state, the process proceeds to step S244, and the special symbol setting result is deleted from the special symbol storage unit 134. Then, the process proceeds to step S245, and (0) is set in the special symbol process flag of the flag storage unit 135. In a state where the special symbol process flag is set to (0), the next special symbol process process proceeds to the big hit determination process of step S151, and the value of the random counter MR1 is stored in the special symbol reservation data storage unit 132 of the reservation number 1. If it is recorded, whether or not it is a big hit is determined with a big hit probability according to the set state of the game mode.

If the CPU 61 determines in step S243 that the big hit flag of the flag storage unit 135 is set to the on state, the CPU 61 sets the big hit flag of the flag storage unit 135 to the off state in step S246, and the counter of the counter storage unit 137 in step S247. By setting (1) to MN1, the game mode is temporarily set to the low probability mode 1 temporarily during the big hit game. In step S248, the limit number (1) is set in the counter MN3 of the counter storage unit 137, and in step S249, the limit time (0.1 × 1000 msec) is set in the timer MT2 of the timer storage unit 136. Next, in step S250, (5) is set in the special symbol process flag of the flag storage unit 135, and in step S251, the lower special prize opening solenoid 40 is turned on to open the lower special prize opening 36. Each of the limit number and limit time is recorded in advance in the ROM 62, and the limit number corresponds to the maximum number of game balls allowed to enter the lower special winning opening 36 in the lower big hit round. The time corresponds to the maximum time allowed to keep the lower special winning opening 36 open in the lower big hit round.
[2-6-6] Lower big hit round processing FIG. 41 shows lower big hit round processing in step S156. This lower big hit round process is executed when the special symbol process flag of the flag storage unit 135 is set to (5). In step S261, the CPU 61 starts the unit value (4 msec) from the timer MT2 of the timer storage unit 136. ) Is updated to update the remaining opening time of the lower special winning opening 36, and the subtraction result of the timer MT2 in the timer storage unit 136 is compared with the limit value (0) in step S262. If it is determined that “MT2 = 0”, the process proceeds to step S266, and the lower special prize opening solenoid 40 is turned off to return the lower special prize opening 36 from the open state to the closed state.

  If the CPU 61 determines that “MT2> 0” in step S262, it determines whether or not a lower special prize signal is output from the lower special prize opening sensor 37 in step S263. If it is determined that a lower special prize signal is output from the lower special prize opening sensor 37, the process proceeds to step S264, and the unit value (1) recorded in advance in the ROM 62 from the counter MN3 of the counter storage unit 137 is obtained. The remaining limit number is updated by subtraction, and the process proceeds to step S265.

  In step S265, the CPU 61 compares the subtraction result of the counter MN3 in the counter storage unit 137 with the limit value (0). If it is determined that “MN3 = 0”, the process proceeds to step S266, and the lower special winning opening 36 is returned from the open state to the closed state. In other words, the lower special winning opening 36 is closed when the limit number (1) of game balls are won in the lower special winning opening 36 or the opening time of the lower special winning opening 36 reaches the limit time (0.1 × 1000 msec). Is done.

When the lower special winning opening 36 is closed in step S266, the CPU 61 sets the limit number (1) in the counter MN3 of the counter storage unit 137 in step S267, and sets the limit time (in the timer MT2 of the timer storage unit 136 in step S268). 0.1 × 1000 msec). In step S269, the upper special prize opening solenoid 45 is turned on to switch the upper special prize opening 41 from the closed state to the opened state. In step S270, (6) is set in the special symbol process flag of the flag storage unit 135.
[2-6-7] Upper jackpot round process FIG. 42 shows the upper jackpot round process in step S157. This upper jackpot round process is executed when the special symbol process flag of the flag storage unit 135 is set to (6), and the CPU 61 executes the unit value (4 msec) from the timer MT2 of the timer storage unit 136 in step S271. ) Is updated, the remaining opening time of the upper special winning opening 41 is updated, and the subtraction result of the timer MT2 in the timer storage unit 136 is compared with the limit value (0) in step S272. If it is determined that “MT2 = 0”, the process proceeds to step S276, and the upper special winning opening 41 is turned off to return the upper special winning opening 41 from the open state to the closed state.

  If the CPU 61 determines that “MT2> 0” in step S272, it determines in step S273 whether or not an upper special prize signal is output from the upper special prize opening sensor 42. If it is determined that the upper special prize signal is output from the upper special prize opening sensor 42, the process proceeds to step S274, and the unit value (1) recorded in advance in the ROM 62 from the counter MN3 of the counter storage unit 137 is obtained. The remaining limit number is updated by subtraction, and the process proceeds to step S275.

  In step S275, the CPU 61 compares the subtraction result of the counter MN3 in the counter storage unit 137 with the limit value (0). If it is determined that “MN3 = 0”, the process proceeds to step S276, and the upper special winning opening 41 is returned from the open state to the closed state. In other words, the upper special winning opening 41 is closed when the limit number (1) of game balls are won in the upper special winning opening 41 or the opening time of the upper special winning opening 41 reaches the limit time (0.1 × 1000 msec). Is done.

  When the upper special winning opening 36 is closed in step S276, the CPU 61 detects the special symbol setting result from the special symbol storage unit 134 in step S277, and sets the value of the counter MN4 in the counter storage unit 137 to the limit value (step S278). 1000). If it is determined that “MN4 = 1000”, the process proceeds to step S279, and an initial value (0) is set as the value of the counter MN4 in the counter storage unit 137. That is, the counter MN4 is reset to the initial value (0) when the total number of continuations of the probability variation mode 1 and the probability variation mode 2 reaches 1000 times.

  When proceeding to step S280, the CPU 61 determines whether or not the detection result of the special symbol is the low probability winning symbol 1 (1). If it is determined that the detection result of the special symbol is the low probability big hit symbol 1 (1), in step S281, the value of the counter MN1 in the counter storage unit 137 is set to (1), thereby reducing the game mode. In the mode 1, the special symbol setting result is erased from the special symbol storage unit 134 in step S287, and (0) is set to the special symbol process flag in the flag storage unit 135 in step S288.

  If the CPU 61 determines in step S280 that the detection result of the special symbol is not the low probability winning symbol 1 (1), it determines whether or not the detection result of the special symbol is the low probability winning symbol 2 (2) in step S282. If it is determined that the special symbol detection result is the low probability winning symbol (2), the game mode is set to the low probability mode by setting (2) to the value of the counter MN1 of the counter storage unit 137 in step S283. In step S287, the special symbol setting result is deleted from the special symbol storage unit 134. In step S288, (0) is set in the special symbol process flag of the flag storage unit 135.

  If the CPU 61 determines in step S282 that the special symbol detection result is not the low probability winning symbol 2 (2), it determines in step S284 whether or not the special symbol detection result is the probability variation large winning symbol 1 (3). If it is determined that the detection result of the special symbol is the probability variation big hit symbol 1 (3), the game mode is set to the probability variation mode 1 by setting the value of the counter MN1 of the counter storage unit 137 to (3) in step S285. In step S287, the special symbol setting result is deleted from the special symbol storage unit 134. In step S288, the special symbol process flag in the flag storage unit 135 is set to (0).

  When the detection result of the special symbol is the probability variation big hit symbol 2 (4), the CPU 61 proceeds from step S284 to step S286, and sets the value of the counter MN1 of the counter storage unit 137 to (4) to change the game mode. Set to probability variation mode 2. In step S287, the special symbol setting result is deleted from the special symbol storage unit 134. In step S288, (0) is set in the special symbol process flag of the flag storage unit 135. That is, if the low probability big hit symbol 1 (1) is stopped and displayed in the special symbol game video, the game mode is set to the low probability mode 1 at the time when the next big hit game ends, and the special symbol game video is displayed. When the low probability big hit symbol 2 (2) is stopped and displayed, the game mode is set to the low probability mode 2 when the next big hit game ends, and the probability variation big hit symbol 1 (3) is displayed in the special symbol game image. When the stop is displayed, the game mode is set to probability change mode 1 at the time when the next big hit game ends, and when the probability change big hit symbol 2 (4) is stopped and displayed in the special symbol game video, When the game is over, the game mode is set to the probability change mode 2.

  FIG. 43 illustrates the transition of the game mode. When the power is turned on, the game mode is set to the low probability mode 1 (MN1 = 1) in step S2 of FIG. 22, and the value of the counter MN4 is set to the initial value (0). ). When the big hit determination result is selected by winning the game ball in the upper special symbol starting port 25 in the low probability mode 1 setting state, the unit value (1) is set to the counter MN4 in step S173 of FIG. In step S174, the probability variation big hit symbol 1 (3) is selected from the special symbol selection table 2 for the low probability mode 1 with a probability of 100%. When the probability variation big hit symbol 1 (3) is selected from the special symbol selection table 2, the probability variation big hit symbol 1 (3) is stopped and displayed on the special symbol display 46 with the special symbol game video, and the special symbol game video is displayed. When the probability variation big hit symbol 1 (3) is stopped and displayed, the lower big hit round and the upper big hit round are sequentially performed, and the game mode is set to the probability variation mode 1 at the end of the upper big hit round. The lower big hit round is to open the lower special prize opening 36 for a time (0.1 × 1000 msec) that is difficult for the player to visually recognize the opening of the lower special prize opening 36. The big hit round is to open the upper special winning opening 41 for a time (0.1 × 1000 msec) during which it is difficult for the player to visually recognize the opening of the upper special winning opening 41. It is difficult for the player to notice the opening of the lower special winning opening 36 and the opening of the upper special winning opening 41.

  When the winning result is selected by winning the game ball in the upper special symbol start opening 25 in the setting state of the probability variation mode 1, the unit value (1) is added to the counter MN4 in step S173 of FIG. In step S174, a special symbol is selected from the special symbol selection table 4 for the probability variation mode 1. When a special symbol is selected from the special symbol selection table 4, the special symbol selection result is stopped and displayed on the special symbol display 46 with the video of the special symbol game, and the game mode is set to the special symbol at the end of the top jackpot round. It is set according to the selection result. In this special symbol selection table 4, the selection probability of probability variation big hit symbol 1 (3) is set to a high probability (299/300), and the selection probability of probability variation big hit symbol 2 (4) is set to a low probability (1/300). In the probability variation mode 1, the probability variation big hit symbol 1 (3) is selected with higher probability than the probability variation big hit symbol 2 (4). In other words, when the jackpot determination result is selected in the probability variation mode 1 setting state, the game mode is reset to the probability variation mode 1 with a high probability, so that the value of the counter MN4 is limited by continuing the probability variation mode 1. Added towards the value.

  When the game ball passes through the normal symbol start port 23 in each of the low probability mode 1 setting state and the probability variation mode 1 setting state, the hit determination table 1 is detected in step S95 of FIG. A determination result corresponding to the value of the random counter MR4 is selected from the determination table 1. In this hit determination table 1, the hit probability for selecting the hit determination result is set to an extremely low value (1/1000), and the game ball is set in each of the low probability mode 1 setting state and the probability variation mode 1 setting state. However, when the game passes through the normal symbol starting port 23, the game is not performed when the lower special symbol starting port 27 is opened with a very high probability.

  When the jackpot determination result is selected for the 1000th time in the setting state of the probability variation mode 1, the value of the counter MN4 is added to the limit value (1000) in step S173 in FIG. 35, and from the special symbol selection table 1 in step S174. The low probability winning symbol 2 (2) is selected with a probability of 100%. When this low probability winning symbol 2 (2) is selected, the special symbol display 46 displays the special symbol game video with the low probability large winning symbol 2 (2) stopped, and the game mode is set at the end of the upper big hit round. The low probability mode 2 is set, and the value of the counter MN4 is reset to the initial value (0). When the big hit determination result is selected in the low accuracy mode 2 setting state, the value of the counter MN4 is added in step S173 of FIG. 35, and the probability change big hit with a probability of 100% from the special symbol selection table 3 in step S174. Symbol 2 (4) is selected. When this probable jackpot symbol 2 (4) is selected, the probable jackpot symbol 2 (4) is stopped and displayed on the special symbol display 46 on the special symbol game video, and the game mode is changed to the probable mode at the end of the top jackpot round. 2 is set.

  When the game ball passes through the normal symbol start port 23 in each of the low probability mode 2 setting state and the probability variation mode 2 setting state, the hit determination table 2 is detected in step S96 of FIG. A determination result corresponding to the value of the random counter MR4 is selected from the determination table 2. In this hit determination table 2, the hit probability is set to a very high value (999/1000), and the game ball passes through the normal symbol start port 23 in each of the low-precision mode 2 setting state and the probability variation mode 2 setting state. In such a case, the winning game is performed by determining that the winning is a very high probability. In this winning game, the lower special symbol starting port 27 is opened. During the winning game, the game ball is allowed to win in the upper special symbol starting port 25 and the lower special symbol starting port 27, respectively. The game ball is prohibited from winning in the lower special symbol starting port 27 except during a winning game.

  The winning game is in a state where the lower special symbol starting port 27 is opened for a longer time (5.9 × 1000 msec) than the total opening time of the upper special winning port 36 and the lower special winning port 41 (0.2 × 1000 msec). The maximum number (10) of game balls allowed to win in the lower special symbol starting port 27 in a winning game is allowed to win in the upper special winning port 36 in a big hit game. The lower special symbol starting port is set to a larger number than the total number of gaming balls allowed (1) and the maximum number of gaming balls allowed to enter the lower special winning opening 41 (1). When one game ball wins in 27, the number of payout balls (15) to be paid out in the upper plate 4 is the upper plate when one game ball wins in the lower special winning port 36. Number of prize balls to be paid out within 4 (3) and top special The number is set to be larger than the number of payout balls (3) to be paid out in the upper plate 4 when one game ball wins in the winning opening 41. In other words, the hit game is more advantageous to the player in which the total payout number of game balls is set to be larger than that of the big hit game.

  When the value of the counter MN4 reaches the limit value based on the change of the game mode from the low probability mode 1 to the probability change mode 1, the game mode is changed to the low probability mode 2. When it is determined that the big hit is determined in the low-precision mode 2 setting state, the gaming mode is changed from the low-precision mode 2 to the probability change mode 2, and each of the low-precision mode 2 setting state and the probability change mode 2 setting state When the game ball passes through the normal symbol start port 23, a winning game is performed, so that a larger number of prize balls are paid out into the upper plate 4 than in the big hit game. The jackpot probability in probability variation mode 1 is set to a high probability (999/1000) close to 100%, and the number of jackpot decisions is limited based on the game mode being changed from low probability mode 1 to probability variation mode 1. The limit value is reached by displaying a special symbol image of a variable number of times approximating the value on the special symbol display 46. In other words, if the player starts playing immediately after opening the pachinko hall, the game ball will be displayed at the normal symbol start opening after the special symbol game image over 1000 times that approximates the limit value is displayed after the game is started. Since the game is played when the player passes through 23, a limit value (ceiling) is set for the number of times the special symbol game video is displayed until the player's advantageous state occurs.

  If the big hit determination result is selected by winning the game ball in either the upper special symbol starting port 25 or the lower special symbol starting port 27 in the setting state of the probability variation mode 2, in step S173 of FIG. The unit value (1) is added to the counter MN4, and a special symbol is selected from the special symbol selection table 5 in step S174. In this special symbol selection table 5, the selection probability of probability variation big hit symbol 1 (3) is set to a low probability (1/30), and the selection probability of probability variation big hit symbol 2 (4) is set to a high probability (29/30). In the probability variation mode 2, the probability variation big hit symbol 2 (4) is selected with higher probability than the hidden probability variation big hit symbol 1 (3). When the probability variation big hit symbol 2 (4) is selected from the special symbol selection table 5, the game mode is reset to the probability variation mode 2. Therefore, when the game ball passes through the normal symbol start port 23, The player's advantageous state is started with a very high probability.

  If the probability variation big hit symbol 1 (3) is selected from the special symbol selection table 5 before the value of the counter MN4 reaches the limit value in the setting state of the probability variation mode 2, the game mode is changed from the probability variation mode 2 to the probability variation mode 1. Be changed. In this case, the value of the counter MN4 is continuously added by selecting the jackpot determination result without resetting the value of the counter MN4 to the initial value (0). In other words, the probability variation mode 2 is changed to the probability variation mode 1 when the probability variation big hit symbol 1 (3) is selected before the value of the counter MN4 reaches the limit value, and the game ball is normally changed to the symbol starting port 23. The player's advantageous state that the game is started with a very high probability when passing through the game is that the game mode is changed from the probability variation mode 2 to the probability variation mode 1 before the value of the counter MN4 reaches the limit value. Disappear.

When the probability variation big hit symbol 2 (4) is selected from the special symbol selection table 4 before the value of the counter MN4 reaches the limit value in the setting state of the probability variation mode 1, the game mode is changed from the probability variation mode 1 to the probability variation mode 2. Be changed. In this case, the value of the counter MN4 is continuously added by selecting the jackpot determination result without resetting the value of the counter MN4 to the initial value (0). That is, the possibility that the game mode is changed from the probability variation mode 1 to the probability variation mode 2 when the jackpot determination result is selected in the probability variation mode 1 setting state is set, and the probability variation mode 1 setting state and the probability variation mode 2 Since the value of the counter MN4 is continuously added when the jackpot determination result is selected in each of the setting states, the upper special symbol starting port from the time when the probability variation mode 2 is set to the next time is set. When the player measures the total number of winning game balls for 25 and the total number of winning game balls for the lower special symbol starting port 27, it becomes difficult to grasp the timing when the value of the counter MN4 reaches the limit value.
[11] Main Processing FIG. 44 is a main processing executed by the CPU 91 of the effect control circuit 90 when the power is turned on. When the power is turned on, the CPU 91 performs register and PIO (parallel input / output port) processing in step S401. Initialize each one.

The CTC (counter / timer) is set as follows.

When the CPU 91 is initially set in step S403, the CPU 91 repeats the counter update process in step S404. In this counter updating process, each of the random counter SR1, the random counter SR2, and the random counter SR3 in the counter storage unit 144 is updated by a unit value (1) recorded in advance in the ROM 92, and the random counter SR1 has a lower limit value (0). ) To the upper limit value (249) and then cyclically added back to the lower limit value “0”, and the random counter SR2 is added from the lower limit value (0) to the upper limit value (162) and then the lower limit value (0 The random counter SR3 is added from the lower limit value (0) to the upper limit value (72) and then returned to the lower limit value (0) and added cyclically. Each of these random counter SR1 to random counter SR3 is initialized to the lower limit value (0) in step S402.
[12] External interrupt processing When a hold command, a hit game start command, a hit game stop command, a change start command, a symbol information command, and a change stop command are transmitted from the main control circuit 60, an external interrupt is generated in the CPU 91. To do. This external interrupt is generated separately from the timer interrupt, and the CPU 91 enters an interrupt disabled state when an external interrupt occurs. When this external interrupt occurs, the CPU 91 stores each of the hold command to the fluctuation stop command in the reception command buffer, and cancels the interrupt disabled state.
[13] Timer Interrupt Processing FIG. 45 shows timer interrupt processing executed by the CPU 91 every 10 msec when a timer interrupt occurs. The CPU 91 executes command processing at step S411 and pending command processing at step S412 every time a timer interrupt occurs. Each of the decorative symbol game process of S413 and the winning game process of step S414 is executed in this order.
[13-1] Command Processing In the command processing in step S411 in FIG. 45, the hold command, the hit game start command, the hit game stop command, the change start command, the symbol information command, and the change stop command are recorded in the reception command buffer. If it is determined that a pending command is recorded in the reception command buffer, the pending command is shifted from the reception command buffer to the command storage unit 141, and the game start command hits the reception command buffer. If it is determined that a game stop command is recorded, the hit game start command is shifted from the received command buffer to the command storage unit 141. If it is determined that a game stop command is recorded in the received command buffer, the game is stopped. Command received from command buffer When it is determined that the change start command is recorded in the reception command buffer, the change start command is shifted from the reception command buffer to the command storage unit 141, and the symbol information command is stored in the reception command buffer. If it is determined that it is recorded, the symbol information command is shifted from the received command buffer to the command storage unit 141. If it is determined that the variable stop command is recorded in the received command buffer, the variable stop command is received. Shift from the buffer to the command storage unit 141.
[13-2] Hold Command Processing FIG. 46 shows the hold command processing in step S412, and the CPU 91 determines whether or not a hold command is recorded in the command storage unit 141 in step S421. If it is determined that a pending command is recorded in the command storage unit 141, the process proceeds to step S422, and the second byte data of the pending command is detected from the command storage unit 141. Then, the process proceeds to step S423, and when the detection result of the second byte data is 01h, the hold display command 1 is transmitted to the display control circuit 100, and when the detection result of the second byte data is 02h. Transmits the hold display command 2 to the display control circuit 100, and when the detection result of the second byte data is 03h, transmits the hold display command 3 to the display control circuit 100, and the detection result of the second byte data. Is 04h, the hold display command 4 is transmitted to the display control circuit 100. In any case, the hold command is cleared from the command storage unit 141 in step S424.

When receiving the hold display command 1, the display control circuit 100 detects the image data corresponding to the hold display command 1 from the VROM, and 1 based on the detection result of the image data in the hold area 49 of the decorative symbol display 48. The pieces of reserved picture 50 are displayed. When receiving the hold display command 2, the display control circuit 100 detects image data corresponding to the hold display command 2 from the VROM, and 2 based on the detection result of the image data in the hold area 49 of the decorative symbol display 48. The pieces of reserved picture 50 are displayed.

1) It is determined with a predetermined normal probability that the special symbol starting device is to be in a hit state, and is determined to be a big hit to have the special ball opening device in an open state. Normal probability mode 1 judging by normal probability
2) Normal probability mode 2 in which it is determined with a predetermined high probability that is higher than that in the normal probability mode 1 when it is a hit, and is determined with a constant normal probability that is the same as the normal probability mode 1 in the case of a big hit
3) If it is a hit, it is determined with the same normal probability as in the normal probability mode 1, and if it is a big hit, it is determined with a predetermined high probability that is higher than each of the normal probability mode 1 and the normal probability mode 2. High probability mode 1
4) When it is a hit, it is determined with a predetermined high probability that is higher than each of the normal probability mode 1 and the high probability mode 1, and when it is a big hit, it is compared with each of the normal probability mode 1 and the normal probability mode 2 High probability mode 2 with high constant and high probability
When a game ball enters the normal symbol start opening device, the hit counter value updating result of the hit counter updating means is detected, and whether or not it is a hit based on the hit counter value detection result. A hit determination means for determining with a probability according to the setting result of the game mode of the game mode setting means,
A normal symbol display on which the determination result of the hit determination means is displayed when it is determined whether or not the hit determination means is a win;
When the hit determination means determines that the win is successful, a hit game is started in which the special symbol start opening device is put into a hit state after the determination result of the hit determination means is displayed on the normal symbol display. In addition, a winning game means for performing a game with a content set to a predetermined number of predetermined number of prize balls to be paid out to the player when the game ball enters the special symbol start opening device as a winning game When,
When a game ball enters the special symbol start opening device, the update result of the value of the jackpot counter of the jackpot counter update means is detected, and whether or not it is a jackpot based on the detection result of the value of the jackpot counter Jackpot determination means for determining with a probability according to the setting result of the game mode of the game mode setting means,
When the power is turned on, the value of the limit counter is reset to a predetermined initial value, and the value of the limit counter is set to a predetermined constant value when the jackpot determination means determines that the jackpot is big. Limit counter updating means for updating only,
Limit counter determining means for determining whether or not the update result of the limit counter value has reached a predetermined limit value when the limit counter updating means has updated the value of the limit counter;
Determining whether the game mode is set to the normal probability mode 1, the normal probability mode 2, the high probability mode 1 or the high probability mode 2 when the jackpot determining means determines that the game is a big hit, When it is determined that the update result of the limit counter value of the limit counter updating means has not reached the limit value, one of the following 11) processing, 12) processing, 13) processing, and 14) processing is performed. A game mode determination means for determining the setting of the normal probability mode 2 when it is determined that the game mode is determined by the above and the update result of the value of the limit counter of the limit counter update means has reached the limit value;
11) Processing for determining setting of high probability mode 1 when current setting result of game mode is normal probability mode 1 12) High probability mode 2 when current setting result of game mode is normal probability mode 2 13) When the current setting result of the game mode is the high probability mode 1, the setting of the high probability mode 1 is determined with a predetermined high probability, and the setting of the high probability mode 2 is set. Processing for determining with a low probability that is lower than the high probability 14) When the current setting result of the game mode is the high probability mode 2, the setting of the high probability mode 1 is determined with a predetermined low probability The process of determining the setting of the high probability mode 2 with a constant high probability that is higher than the low probability When the update result of the limit counter value of the limit counter updating means is determined to have reached the limit value Limit counter reset means for resetting the limit counter value after the game mode determination means determines the game mode, and resets the limit counter value to the same initial value as when the power is turned on. ,
A special symbol display for displaying the determination result of the jackpot determining means when it is determined whether the jackpot determining means is a jackpot,
When the jackpot determining means is determined to be a big hit, a jackpot game is performed for opening the special entrance device after the determination result of the jackpot determining means is displayed on the special symbol display. , With the content that the limited number of prize balls to be paid out to the player when the game ball enters the special entrance device as a big hit game is set to a small number which is smaller than the limit number in the hit game With a big hit game means
The pachinko gaming machine characterized in that the game mode setting means sets the game mode to the determination result of the game mode determination means when the jackpot game means finishes the big hit game.
