Description

  The present invention relates to a pachinko gaming machine configured to determine whether or not a big hit is made when a game ball enters a special symbol start opening.

  Some pachinko gaming machines are configured to determine whether or not a big hit is made when a game ball enters a special symbol starting port, and to play a big hit game when it is determined that the game is a big hit. This jackpot game allows the game ball to enter the special entrance by opening the special entrance, and in the jackpot game, one game ball enters the special entrance. Each time, a unit number of game balls are paid out to the player as a prize. When the high probability mode is set to the off state, the pachinko machine determines that it is a big hit with a normal probability, and when the high probability mode is set to the on state, the normal probability that it is a big hit. There is a configuration in which the determination is performed with high probability compared to the above. When it is determined that the high probability mode is a big hit, it is determined whether to set the off state or the on state. When it is determined that the high probability mode is set to the off state, the high probability mode is stored in the memory. When the high probability flag is recorded in the off state, the high probability mode is set to the off state, and when it is determined that the high probability mode is set to the on state, the high probability flag is recorded to the memory in the on state. The high probability mode is set to ON.

  Patent Document 1 describes that the probability variation mode is updated by a certain value every time the probability variation mode is turned on. This cited reference 1 uses the number of probability variation modes as a means for forcibly terminating the continuous state, and when the number of probability variation modes reaches the limit, the probability variation mode is forcibly turned off. At the same time, the number of probability variation modes is reset.

If the game ball is judged to be a big hit because the game ball has entered the first special symbol starting port, the electric chew support mode can be used regardless of whether the probability variation mode is off or on. The number of times that it is difficult to be determined to be a big hit again in the mode on state, and when the game ball is determined to be a big hit by entering the second special symbol starting port, the off state and the on state of the probability variation mode are set. In any case, the number of times is easily determined to be a big hit again in the ON state of the electric chew support mode. 47, step S348 in FIG. 47, step S348 in FIG. 48, step S375 in FIG. 48, step S376 in FIG. 48, step S396 in FIG. 49, step S398 in FIG. 49, step S399 in FIG. 49, and step S401 in FIG. MN1 corresponds to the number of times of the electric chew support mode, (4) corresponds to the number of times that is difficult to be determined as a big hit, and (70) corresponds to the number of times that is easily determined to be a big hit.
[13] In the on state of the electric chew support mode, every time it is determined whether or not the game ball is a big hit because it has entered the first special symbol starting port and the second special symbol starting port. A means for updating the number of times of the chew support mode by a certain value to the limit, and when the number of times of the electric chew support mode reaches the limit, means for turning the electric chew support mode off. Steps S252, S254, S256, and S258 in FIG. 40 correspond to the means.

  When the number of times of the electric chew support mode is set to a number that is easily determined to be a big hit again in the on state of the electric chew support mode, the probability variation big hit is easily selected in the on state of the electric chew support mode. That is, when the number of times of the electric chew support mode is set to the number of times that it is easily determined that the game is a big hit in the on state of the electric chew support mode, the continuous change state is reached, and the number of times of the probability variation mode reaches the limit. When the number of times of the probability variation mode reaches the limit, a big hit game that allows a large number of game balls to enter the special entrance is performed. A ball can be paid out.

When the game ball wins the upper special symbol start opening 25, it is determined whether or not it is a big hit. A special symbol game video is displayed on the special symbol display 39. This special symbol game image changes the special symbol in a predetermined order (1) → (2) → (3) → (4) → (5) → (1). When it is determined that the game ball wins in the upper special symbol start opening 25 and is not a big hit, the cyclic variation display of the special symbol on the upper special symbol display 39 stops at (1). When it is determined that the game is a big hit, the cyclic variation display of the special symbol on the upper special symbol display 39 stops at either (2) or (3). This special symbol (1) is referred to as an outlier symbol, the special symbol (2) is generally referred to as a jackpot symbol 1, the special symbol (3) is referred to as a probabilistic jackpot symbol 1, and the special symbol (4) is referred to as a regular jackpot symbol 2. The special symbol (5) is referred to as probability variation big hit symbol 2.

  When the normal special jackpot symbol 1 (2) is stopped and displayed on the upper special symbol display 39 with the video of the special symbol game, the normal jackpot game 1 is started. This normal jackpot game 1 is composed of 15 jackpot rounds. Each of these 15 jackpot rounds opens the special prize opening 34, and the first to eleventh big hit rounds each have an upper limit number (10) of game balls winning in the special prize opening 34. Or when the opening time of the special winning opening 34 reaches the upper limit time (0.8 sec), and each of the 12th to 15th big hit rounds has an upper limit number (10) of game balls. The process ends either when a special prize opening 34 is won or when the opening time of the special prize opening 34 reaches the upper limit time (30 sec). When the probability variation big hit symbol 1 (3) is stopped and displayed on the upper special symbol display 39 by the video of the special symbol game, the probability variation big hit game is started. This probable big hit game is composed of four big hit rounds. Each of these four jackpot rounds is to open the special prize opening 34, and each of the first to fourth jackpot rounds has an upper limit number (10) of game balls winning in the special prize opening 34. Or when the opening time of the special prize opening 34 reaches the upper limit time (30 sec).

  The hitting ball 9 is driven so as to fire game balls at a constant rate (99 pieces / minute) in the game board 16 and is usually awarded a special prize in each of the first to eleventh big hit rounds of the big hit game 1 When the opening time of the special prize opening 34 reaches the upper limit time before the upper limit number of game balls wins in the mouth 34, the special prize opening 34 is closed, and usually the 12th to 15th times of the big hit game 1 In each jackpot round, the special prize opening 34 is closed when the upper limit number of game balls are won in the special prize opening 34 before the opening time of the special prize opening 34 reaches the upper limit time. In each of the first to fourth big hit rounds, the special prize opening 34 is closed by the upper limit number of game balls winning in the special prize opening 34 before the opening time of the special prize opening 34 reaches the upper limit time. That. That is, the normal big hit game 1 is substantially composed of four big hit rounds, and is set to the same degree of advantage as the probable big hit game in the player's line of sight.

  As shown in FIG. 2, a lower special symbol display 40 is fixed to the display frame 32. The lower special symbol display 40 is composed of a dot matrix type LED display. When the game ball wins in the lower special symbol start opening 27, it is determined whether or not it is a big hit. The display of the special symbol game video is started on the special symbol display 40. The video of this special symbol game is the same order as the case where the game ball wins the special symbol in the upper special symbol start opening 25 (1) → (2) → (3) → (4) → (5) → (1 )... Is cyclically changed, and when it is determined that the game ball is defeated by winning in the lower special symbol start opening 27, the special symbol of the lower special symbol display 40 is circulated. If the fluctuation display is out of place and stops at symbol (1) and it is determined that it is a big hit, the cyclic fluctuation display of the special symbol on the lower special symbol display 40 is usually a big hit symbol 2 (4) and a probable big hit Stop at any of symbols 2 (5).

  If the normal big hit symbol 2 (4) is stopped and displayed on the lower special symbol display 40 with the video of the special symbol game, the normal big hit game 2 is started. The normal jackpot game 2 is composed of 15 jackpot rounds. Each of these 15 big hit rounds is to open the special prize opening 34, and when the upper limit number (10 pieces) of game balls wins in the special prize opening 34 and the opening time of the special prize opening 34 The process is terminated when the upper limit time (30 sec) is reached. When the probability variation big hit symbol 2 (5) is stopped and displayed on the lower special symbol display 40 with the image of the special symbol game, the probability variation big hit game is started. This probable big hit game is composed of the same four big hit rounds as when the probable big hit symbol 1 (3) is stopped and displayed on the upper special symbol display 39, and each of the first to fourth big hits The round ends either when the upper limit number (10) of game balls have won in the special winning opening 34 or when the opening time of the special winning opening 34 has reached the upper limit time (30 sec). FIG. 4 shows the relationship between special symbols and jackpot games.

  When the special jackpot symbol 1 (2) is stopped and displayed in the special symbol game image on the upper special symbol display 39, the probability variation mode is turned off when the final 15th jackpot round is completed in the jackpot game. In addition, when the electric chew support mode 1 is set to the on state and the special symbol game image 1 (3) is stopped and displayed on the upper special symbol display 39 with the video of the special symbol game, the final four in the jackpot game When the second jackpot round ends, the probability variation mode is set to the on state, and the electric chew support mode 1 is set to the on state. The probability variation mode is a mode in which a game ball is judged with a certain high probability (1/35) that it is a big hit each when winning in the upper special symbol starting port 25 and winning in the lower special symbol starting port 27 In the off state of the probability variation mode, when the game ball wins in the upper special symbol starting port 25 and when it wins in the lower special symbol starting port 27, it is lower than the high probability. The normal probability (1/36) is determined. In the electric chew support mode 1, by setting the opening time of the lower special symbol start port 27 in the hit game to a fixed long time (4.0 sec), more game balls can be obtained than in the off state of the electric chew support mode 1. It is a mode that allows winning in the lower special symbol start opening 27, and is switched to the off state by displaying the video of the special symbol game of the limit number of times (four times) in the on state of the electric support mode 1. .

  When the special bonus game 2 (4) is stopped and displayed on the special symbol game 40 on the lower special symbol display 40, the probability variation mode is turned off when the final 15th big hit round is completed in the big bonus game. In addition, when the electric chew support mode 2 is set to the on state and the upper symbol display 39 is displayed with the special symbol game image 2 (5) stopped on the special symbol game image, the final 4 in the jackpot game is displayed. When the big jackpot round ends, the probability variation mode is set to the on state, and the electric chew support mode 2 is set to the on state. Electric Chu Support Mode 2 is set to the same long time (4.0 sec) as Electric Chu Support Mode 1 for opening the lower special symbol start opening 27 in the hit game, compared to the off state of Electric Chu Support Mode 2 In this mode, a large number of game balls are allowed to win in the lower special symbol start opening 27, and a special symbol game image of the limit number of times (70 times) is displayed in the ON state of the electric chew support mode 2. Can be switched off. FIG. 5 shows the relationship between special symbols and game modes.

  As shown in FIG. 2, a decorative symbol display 41 composed of a color liquid crystal display is fixed to the display frame 32. A holding area 42 is set in the display area of the decorative symbol display 41. Each of the cases where the game ball wins in the upper special symbol start opening 25 and in the lower special symbol start opening 27, respectively. Is added with the number of holdings of special symbol games, and the result of adding the number of holdings is displayed in the holding area 42 in any case. Each of the addition results of the number of holding times of both special symbol games is displayed as the number of common reserved symbols 43, and the player can calculate the total of both special symbol games from the displayed number of reserved symbols 43 in the reserved area 42. You can recognize the number of holds. The decorative symbol display 41 displays an image of a big hit game effect. This big hit game effect video visually produces each of the normal big hit game 1, the normal big hit game 2 and the probable big hit game, and the first big hit round starts in each of the normal big hit game 1 to the probable big hit game Is started, and ends when the last big hit round is stopped in each of the normal big hit game 1 to the probable big hit game.

This normal symbol variation process is executed when the normal symbol process flag of the flag storage unit 116 is set to (1), and the CPU 51 controls the LED of the normal symbol display 33 to blink in step S131. In the normal symbol display 33, the winning symbol (O) and the losing symbol (x) are alternately displayed. Then, the remaining time of the normal symbol game is updated by subtracting a constant value ΔT (4 msec) recorded in advance in the ROM 52 from the value of the timer MT1 of the timer storage unit 117 in step S132, and the value of the timer MT1 is updated in step S133. The subtraction result is compared with a limit value (0) recorded in advance in the ROM 52. If it is determined that “MT1 = 0”, the end of the normal symbol game is determined, and (2) is set in the normal symbol process flag of the flag storage unit 116 in step S134.
[2-6-3] Normal Symbol Fluctuation Stop Processing FIG. 33 shows the normal symbol variation stop processing in step S93. This normal symbol fluctuation stop process is executed when the normal symbol process flag of the flag storage unit 116 is set to (2), and the CPU 51 stops the fluctuation display of the normal symbol in step S141. 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 115. When it is determined that the symbol is a win, the normal symbol variation display is a win symbol (O). If it is determined that it is out of place, the normal symbol variation display is out and stops at the symbol (x).

When the CPU 51 stops displaying the change of the normal symbol in step S141, the CPU 51 clears the recording result of the normal symbol from the normal symbol storage unit 115 in step S142. In step S143, an interval time (1 × 1000 msec) is set as the value of the timer MT1 in the timer storage unit 117. This interval time is recorded in advance in the ROM 52. When the CPU 51 sets the value of the timer MT1 of the timer storage unit 117 in step S143, the CPU 51 sets (3) in the normal symbol process flag of the flag storage unit 116 in step S144. Set.
[2-6-4] Interval Processing FIG. 34 shows the interval processing in step S94. This interval process is executed when the normal symbol process flag in the flag storage unit 116 is set to (3). In step S151, the CPU 51 determines from the value of the timer MT1 in the timer storage unit 117 to a constant value ΔT ( The remaining interval time is updated by subtracting 4 msec). In step S152, the subtraction result of the value of timer MT1 is compared with the limit value (0). If it is determined that “MT1 = 0”, the hit flag of flag storage unit 116 is set to the on state in step S153. It is judged whether it is done. If it is determined that the hit flag in the flag storage unit 116 is set to the off state, the process proceeds to step S154, and the normal symbol process flag in the flag storage unit 116 is set to (0).

  If the CPU 51 determines in step S153 that the hit flag of the flag storage unit 116 is set to the on state, the CPU 51 sets the hit flag of the flag storage unit 116 to the off state in step S155, and the electric power of the flag storage unit 116 in step S156. It is determined whether one of the chew support flag 1 and the electric chew support flag 2 is set to an on state. If it is determined that either the electronic chew support flag 1 or the electronic chew support flag 2 in the flag storage unit 116 is set to the on state, the process proceeds to step S157, and the value of the timer MT1 in the timer storage unit 117 is determined. Is set to the long value LT2 (4 × 1000 msec). The long value LT2 is recorded in advance in the ROM 52, and the CPU 51 determines in step S156 that both the electric chew support flag 1 and the electric chew support flag 2 of the flag storage unit 116 are set to the off state. In step S158, the short value ST2 (0.8 × 1000 msec) is set as the value of the timer MT1 in the timer storage unit 117. This short value ST2 is recorded in advance in the ROM 52, and when it is determined that the win is in the ON state of the electric support mode 1 or the electronic support mode 2, the opening time of the lower special symbol start port 27 is set. When the long value LT2 is set and it is determined that both the electronic chew support mode 1 and the electric chew support mode 2 are off, the opening time of the lower special symbol start port 27 is compared with the long value LT2. A short short value ST2 is set.

When the CPU 51 sets the value of the timer MT1 of the timer storage unit 117 in step S157 or step S158, in step S159, the special symbol start port solenoid 31 is switched from the electrical off state to the on state, thereby opening the lower special symbol start port 27. Switching from the closed state to the open state, (4) is set in the normal symbol process flag of the flag storage unit 116 in step S160.
[2-6-5] Winning Game Processing FIG. 35 shows the winning game processing in step S95. This winning game process is executed when the normal symbol process flag in the flag storage unit 116 is set to (4). In step S171, the CPU 51 determines a constant ΔT from the value of the timer MT1 in the timer storage unit 117. The remaining opening time of the lower special symbol start port 27 is updated by subtracting (4 msec). Then, the subtraction result of the value of the timer MT1 is compared with the limit value (0) in step S172, and if it is determined that “MT1 = 0”, the special symbol start port solenoid 31 is turned on in step S173. The special symbol starting port 27 is switched from the open state to the closed state by switching from the OFF state to the OFF state, and (0) is set to the normal symbol process flag in the flag storage unit 116 in step S174.
[2-7] Special symbol process FIG. 36 shows the special symbol process in step S17. The special symbol process includes the big hit determination process in step S181, the special symbol variation start process in step S182, the special symbol variation process in step S183, the special symbol variation stop process in step S184, the interval process in step S185, and the step S186. The normal big hit game process 1, the normal big hit game process 2 in step S 187, and the probable change big hit game process in step S 188 are included. This is done alternatively according to the setting state of the process flag.
[2-7-1] Big hit determination process FIG. 37 is a big hit determination process in step S181. This jackpot determination process is executed when the special symbol process flag in the flag storage unit 116 is set to (0). The special symbol process flag in the flag storage unit 116 is initialized to (0) in step S2. Is set.

  In step S191, the CPU 51 determines whether or not the value of the random counter MR1 is recorded in the special symbol hold data storage unit 112 of the hold number 1 for the lower special symbol start port 27. Here, when it is determined that the value of the random counter MR1 is recorded in the special symbol holding data storage unit 112 of the holding number 1 for the lower special symbol starting port 27, the holding for the lower special symbol starting port 27 is performed in step S192. Each of the value of the random counter MR1 and the value of the random counter MR3 is detected from the special symbol holding data storage unit 112 of No. 1, and the priority processing flag of the flag storage unit 116 is set to the ON state in step S193. The priority processing flag of the flag storage unit 116 is initially set to an off state in step S2.

  If the CPU 51 determines in step S191 that the value of the random counter MR1 is not recorded in the special symbol hold data storage unit 112 of the hold number 1 for the lower special symbol start port 27 in step S191, the CPU 51 uses the value for the upper special symbol start port 25 in step S194. It is determined whether or not the value of the random counter MR1 is recorded in the special symbol hold data storage unit 111 of the hold number 1. Here, if it is determined that the value of the random counter MR1 is recorded in the special symbol holding data storage unit 111 of the holding number 1 for the upper special symbol starting port 25, the holding for the upper special symbol starting port 25 is performed in step S195. Each of the value of the random counter MR1 and the value of the random counter MR3 is detected from the special symbol holding data storage unit 111 of number 1, and the priority processing flag of the flag storage unit 116 is set to an off state in step S196. That is, the reserved data for the lower special symbol start port 27 is processed with priority over the reserved data for the upper special symbol start port 25, and the reserved data for the upper special symbol start port 25 is the lower special symbol. This is processed when there is no hold data for the start port 27.

  When the priority processing flag of the flag storage unit 116 is set in step S193 or step S196, the CPU 51 determines whether or not the probability change flag of the flag storage unit 116 is set to the on state in step S197. This probability variation flag is initially set to the off state in step S2. When the CPU 51 determines in step S197 that the probability variation flag of the flag storage unit 116 is set to the on state, the CPU 51 reads the figure from the ROM 52 in step S198. 10 (b) jackpot determination table 2 is detected, and a determination result corresponding to the detection result of the value of the random counter MR1 in step S192 or step S195 is selected from the jackpot determination table 2 in step S199.

  If the CPU 51 determines in step S197 that the probability variation flag of the flag storage unit 116 is set to the OFF state, the CPU 51 detects the big hit determination table 1 of FIG. 10A from the ROM 52 in step S200, and the big hit determination table in step S201. A determination result is selected according to the detection result of the value of the random counter MR1 from 1 to step S192 or step S195. In other words, in the ON state of the probability variation mode, when the game ball wins the upper special symbol starting port 25 and when the game ball wins the lower special symbol starting port 27, the same high probability (1/35) is obtained. ), And in the off state of the probability variation mode, when the game ball wins the upper special symbol starting port 25 and when the game ball wins the lower special symbol starting port 27, it is the same normal probability ( 1/36).

  When the CPU 51 selects a determination result in step S199 or step S201, the CPU 51 determines in step S202 whether the determination result in step S199 or the determination result in step S201 is a big hit. Here, when it is determined that the determination result in step S199 or the determination result in step S201 is out of step, the process proceeds to step S203, and the big hit flag in the flag storage unit 116 is set to an off state. This jackpot flag is initially set to the off state in step S2, and when the CPU 51 sets the jackpot flag of the flag storage unit 116 to the off state in step S203, it is removed as a special symbol in step S204 (1). In step S205, the off symbol (1) is recorded in the special symbol storage unit 114, and in step S206, the special symbol process flag in the flag storage unit 116 is set to (1).

  When the CPU 51 determines in step S202 that the determination result in step S199 or the determination result in step S201 is a big hit, the CPU 51 sets the big hit flag in the flag storage unit 116 to an on state in step S207, and the priority of the flag storage unit 116 in step S208. It is determined whether or not the processing flag is set to an off state. If it is determined that the priority processing flag of the flag storage unit 116 is set to the off state, the process proceeds to step S209, and whether or not the value of the counter MN2 of the counter storage unit 118 is set to (1). Judging. The value of the counter MN2 of the counter storage unit 117 is initially set to the initial value (0) recorded in advance in the ROM 52 in step S2, and the CPU 51 determines that “MN2 = 1” in step S209. In step S210, the normal jackpot symbol 1 (2) is selected as the special symbol. In step S205, the normal jackpot symbol (2) is recorded in the special symbol storage unit 114, and (1) is set in the special symbol process flag of the flag storage unit 116 in step S206.

  If the CPU 51 determines in step S209 that the value of the counter MN2 in the counter storage unit 118 is not set to (1), the CPU 51 detects the special symbol selection table 1 in FIG. Then, a special symbol corresponding to the detection result of the value of the random counter MR3 in step S195 is selected from the special symbol selection table 1. In step S205, the special symbol selection result is recorded in the special symbol storage unit 114. In step S206, (1) is set in the special symbol process flag of the flag storage unit 116. This special symbol selection table 1 is usually set with a big jackpot symbol 1 (2) and a probable variation jackpot symbol 1 (3), and it is determined that the game ball is a big hit by winning the top special symbol start opening 25. In this case, the normal jackpot symbol 1 (2) is selected with a low probability (1/100), and the probability variation jackpot symbol 1 (3) is selected with a high probability (99/100).

  If the CPU 51 determines in step S208 that the priority processing flag of the flag storage unit 116 is set to the on state, the CPU 51 determines whether or not the value of the counter MN2 of the counter storage unit 118 is set to (1) in step S213. To do. If it is determined that “MN2 = 1”, the normal jackpot symbol 2 (4) is selected as the special symbol in step S214, and the normal jackpot symbol (2) is recorded in the special symbol storage unit 114 in step S205. In step S206, (1) is set to the special symbol process flag in the flag storage unit 116.

  If the CPU 51 determines in step S213 that the value of the counter MN2 in the counter storage unit 118 is not set to (1), the CPU 51 detects the special symbol selection table 2 of FIG. 11B from the ROM 52 in step S215, and step S216. Then, a special symbol corresponding to the detection result of the value of the random counter MR3 in step S192 is selected from the special symbol selection table 2. In step S205, the special symbol selection result is recorded in the special symbol storage unit 114. In step S206, (1) is set in the special symbol process flag of the flag storage unit 116. This special symbol selection table 2 is usually set with a big jackpot symbol 2 (4) and a probable variation jackpot symbol 2 (5), and it is determined that the game ball is a big hit by winning the lower special symbol start opening 27. In this case, usually the big hit symbol 2 (4) is selected with a low probability (1/100), and the probability variation big hit symbol 2 (5) is selected with a high probability (99/100).

FIG. 38 explains how the value of the counter MN2 is updated. When the value of the counter MN2 is determined to be a big hit with the value set to (0), the probability variation big hit symbol 1 (3) and the probability variation big hit symbol 2 (5) are selected respectively. When the big hit round ends, the probability variation mode is set to the on state, and the probability variation mode is set to the on state, whereby the value of the counter MN2 is set to (2). When the value of the counter MN2 is determined to be a big hit in the state set to (2), the probability variation big hit symbol 1 (3) and the probability variation big hit symbol 2 (5) are selected, respectively. When the big hit round ends, the probability variation mode is set to the on state, and the probability variation mode is set to the on state, whereby the value of the counter MN2 is subtracted from (2) to (1). When the value of the counter MN2 is determined to be a big hit in the state set to (1), either the normal big hit symbol 1 (2) or the normal big hit symbol (4) is forcibly selected, When either of the jackpot symbol 1 (2) and the normal jackpot symbol (4) is selected, the probability variation mode is set to the off state when the final jackpot round is completed. The value of the counter MN2 is reset to (0) when the probability variation mode is set to the off state, and the normal jackpot symbol 1 (2) and the value of the counter MN2 is set to (2). Normally, when any of the big hit symbol (4) is selected, it is reset to (0) without being subtracted from (1). That is, the counter MN2 measures the number of continuations of the probability variation mode in which the probability variation mode is set to the on state while the probability variation mode is in the on state.
[2-7-2] Special symbol variation start process FIG. 39 shows the special symbol variation start process in step S182. This special symbol variation start process is executed when the special symbol process flag of the flag storage unit 116 is set to (1), and the CPU 51 sets the value of the random counter MR2 from the counter storage unit 118 in step S221. In step S222, it is determined whether or not the big hit flag in the flag storage unit 116 is set to the on state. If it is determined that the big hit flag of the flag storage unit 116 is set to the on state, the fluctuation start command table 1 shown in FIG. 14A is detected from the ROM 52 in step S223, and the fluctuation start command is detected in step S224. One fluctuation start command corresponding to the detection result of the value of the random counter MR2 is selected from Table 1.

[2-7-8] Probability variation jackpot game processing FIG. 49 shows the probability variation jackpot game processing in step S188. This probability variation big hit game process is executed when the special symbol process flag of the flag storage unit 116 is set to (7), and the CPU 51 determines a constant value from the value of the timer MT2 of the timer storage unit 117 in step S381. (4 msec) is subtracted, and the subtraction result of the value of timer MT2 is compared with the limit value (0) in step S382. If it is determined that “MT2 = 0”, the process proceeds to step S386, and the special winning opening 34 is closed to end the current big hit round.

  If the CPU 51 determines that “MT2> 0” in step S382, it determines whether or not a special winning signal is output from the special winning opening sensor 35 in step S383. If it is determined that a special prize signal is output from the special prize opening sensor 35, a predetermined value (1) is subtracted from the value of the counter MN4 of the counter storage unit 118 in step S384, and the counter MN4 is counted in step S385. The value subtraction result is compared with the limit value (0).

  If the CPU 51 determines that “MN4 = 0” in step S385, the special winning opening 34 is closed in step S386. In step S387, the constant value (1) is subtracted from the value of the counter MN3 in the counter storage unit 118. In step S388, the subtraction result of the value of the counter MN3 is compared with the limit value (0). If it is determined that “MN3> 0”, the winning limit number (10) is set to the value of the counter MN4 of the counter storage unit 118 in step S389, and the value of the timer MT2 of the timer storage unit 117 in step S390. Is set to the opening limit time (30 × 1000 msec), and the special winning opening 34 is again opened in step S391.

  In the probable big hit game process, the opening time of the special winning opening 34 is set to the limit time (30 × 1000 msec) in each of the first big hit round to the fourth big hit round. Within the limit time (30 × 1000 msec), the limit number (10) of game balls wins in the special prize opening 34. The player operates the launch handle 8 to fire the game balls on the game board 16. In each of the first jackpot round to the fourth jackpot round, the opening time of the special prize opening 34 reaches the limit time (30 × 1000 msec) or the game ball is awarded to the special prize opening 34 When the number reaches the limit number (10), the special winning opening 34 is closed. That is, the probability variation big hit game process is such that a smaller number of game balls can be paid out into the upper plate 4 than the normal big hit game process 1 and the normal big hit game process 2 respectively.

  When the CPU 51 closes the special prize opening 34 for the fourth time in step S386, the CPU 51 subtracts the value of the counter MN3 in the counter storage unit 118 from the limit value (0) in step S387. In step S388, it is determined that “MN3 = 0”, and a big hit game stop command is transmitted to the effect control circuit 70 in step S392. Next, in step S393, the probability variation flag of the flag storage unit 116 is set to an on state, and in step S394, the special symbol recording result is detected from the special symbol storage unit 114. That is, the probability variable big hit symbol 1 (3) is stopped on the upper special symbol display 39 and the probability variable big hit symbol 2 (5) is stopped on the lower special symbol indicator 40, respectively. When the last big hit round ends, the probability variation mode is set to the on state.

  When the CPU 51 detects the recording result of the special symbol from the special symbol storage unit 114 in step S394, it determines in step S395 whether or not the detection result of the special symbol is the probability variation big hit 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 electric support flag 1 of the flag storage unit 116 is set to the ON state in step S396, and the flag storage unit 116 is set in step S397. The electronic chew support flag 2 is set to the OFF state, and the continuation count (4) is set to the value of the counter MN1 of the counter storage unit 118 in step S398. In other words, when the probability variation big hit symbol 1 (3) is stopped and displayed on the upper special symbol display 39, the electric chew support mode 1 is set to the ON state when the final big hit round ends in the probability variation big hit game. At the same time, the electric chew support mode 2 is set to the OFF state, and the number of continuations (4) of the electric chew support mode 1 is set to the value of the counter MN1.

  When CPU 51 determines in step S395 that the detection result of the special symbol is probability variation big hit symbol 2 (5), in step S399, electric chew support flag 1 of flag storage unit 116 is set to an off state, and in step S400, flag storage unit The electronic chew support flag 2 of 116 is set to an ON state, and the continuation count (70) is set to the value of the counter MN1 of the counter storage unit 118 in step S401. That is, when the probability variation big hit symbol 2 (5) is stopped and displayed on the lower special symbol display 40, the electric support mode 1 is set to the off state when the final big hit round is finished in the probability variation big hit game. At the same time, the electric chew support mode 2 is set to the on state, and the number of times of continuing the electric chew support mode 2 (70) is set to the value of the counter MN1.

  When the CPU 51 sets the value of the counter MN1 in step S398 or step S401, the CPU 51 determines whether or not the value of the counter MN2 in the counter storage unit 118 is the initial value (0) in step S402. If it is determined that “MN2 = 0”, the limit value (2) is set to the value of the counter MN2 of the counter storage unit 118 in step S403. If it is determined that “MN2 = 0” is not satisfied, step S403 is performed. In S404, the constant value (1) is subtracted from the value of the counter MN2 in the counter storage unit 118. In step S405, the special symbol recording result is cleared from the special symbol storage unit 114. In step S406, (0) is set in the special symbol process flag of the flag storage unit 116.

FIG. 50 shows the flow of the game. The game flow includes a game loop 1 in which the player can acquire a game ball as a prize in each of the normal jackpot game 1 and the probability variable jackpot game, and the player has a normal jackpot game 2 and Two types of game loops 2 are set for each of the probable big hit games, in which more game balls can be obtained as prizes than the game loop 1. The game loop 1 is a case where the electric chew support mode 1 is set to the on state, and the electric chew support mode 1 is a case where it is determined that the game ball is a big hit by winning the upper special symbol start opening 25 Is set to ON. The game loop 2 is a case where the electric chew support mode 2 is set to the on state, and the electric chew support mode 2 is a case where it is determined that the game ball is a big hit by winning the lower special symbol starting port 27 Is set to ON.
1. Description of the game loop 1 When it is determined that the game ball has passed the normal symbol starting port 23 in the ON state of the electric chew support mode 1, it is determined that the game is a win. The winning game in the on state of the electric chew support mode 1 is easier for the game ball to win the lower special symbol starting port 27 than the winning game in the off state of both the electric chew support mode 1 and the electric chew support mode 2. In the ON state of the electric chew support mode 1, it is highly probable that whether or not the game ball is a big hit by winning the lower special symbol starting port 27. In the on state of the electric support mode 1, the probability variation mode is set to the on state, and a big hit is determined with a higher jackpot probability than the off state of the probability variation mode.

  When it is determined that the game ball is not a big hit by winning the lower special symbol start opening 27, the special symbol game video is displayed on the lower special symbol display 27, and the number of times of display of the special symbol game video is displayed. It is measured, and it is determined whether or not the measurement result of the display count has reached the set result of the continuation count. In the ON state of the electric support mode 1, the number of continuations is set to a number (4) that is significantly smaller than the denominator value (100) of the jackpot probability (1/100), and it is determined that the jackpot is a big hit. There is a high probability that the measurement result of the display count reaches the setting result of the continuation count without any problem. When the measurement result of the display count reaches the setting result of the continuous count, the electric chew support mode 1 is set to the off state, and both the electric chew support mode 1 and the electric chew support mode 2 are in the probability variation mode on state. Turns off.

When it is determined that the game ball is a winning by passing through the normal symbol starting port 23 in both of the electric chew support mode 1 and the electric chew support mode 2, the winning game is performed. The hit game in the OFF state of both the electric chew support mode 1 and the electric chew support mode 2 is lower than the hit game in the ON state of either the electric chew support mode 1 or the electric chew support mode 2. It is difficult to win the special symbol starting port 27, and it is determined whether or not the game ball is a big hit by winning the upper special symbol starting port 25 when both the electric support mode 1 and the electric support mode 2 are off. There is a high probability. In addition, when it is determined that the game ball is won by winning the special symbol start opening 25, the probability big hit symbol 1 out of the normal big hit symbol 1 and the probability variable big hit symbol 1 is higher than the normal jackpot symbol 1. Each of the following 1B) processing to 6B) processing is performed by selection probability. Therefore, when it is determined that the game ball is a big hit by winning the upper special symbol start opening 25, the electric chew support mode 1 is set to the on state again, and the continuation count is set to (4) again. Therefore, each of the following 1B) processing to 6B) processing is repeated, and the measurement result of the number of selections in which either one of probability variation big hit symbol 1 and probability variation big hit symbol 2 is continuously selected as a special symbol is the limit value ( 1) is reached.
1B) The special symbol game video is displayed on the upper special symbol display 39, and the probability variation big hit symbol 1 is stopped and displayed on the special symbol video on the upper special symbol display 39.
2B) A probable big hit game is performed, and the game ball wins a special winning opening 34 in the probable big hit game, so that the game ball is paid out to the player as a prize.
3B) The probability variation mode is set to the on state.
4B) The electric chew support mode 1 is set to the on state, and the electric chew support mode 2 is set to the off state.
5B) The number of continuations from when the electronic chew support mode 1 is set to the on state until it is set to the off state is set to (4).
6B) The number of times that either of the probability variation big hit symbol 1 and the probability variation big hit symbol 2 is continuously selected is measured.

When it is determined that the game ball is a big hit by winning the upper special symbol starting port 25 in a state where the measurement result of the number of selections reaches the limit value (1), the normal big hit symbol 1 is forcibly selected. Each of the following 1A) process to 6A) process is performed.
1A) The special symbol game video is displayed on the upper special symbol display 39, and the normal big hit symbol 1 is stopped and displayed on the special symbol video on the upper special symbol display 39.
2A) A normal jackpot game 1 is performed, and the game ball is awarded to the special winning opening 34 in the normal jackpot game 1, whereby the game ball is paid out to the player as a prize.
3A) The probability variation mode is set to the off state.
4A) The electric chew support mode 1 is set to the on state, and the electric chew support mode 2 is set to the off state.
5A) The number of continuations from when the electronic chew support mode 1 is set to the on state until it is set to the off state is set to (4).
6A) The number of selections in which either the special symbol B or the special symbol B ′ is continuously selected as the special symbol is reset.

When the normal jackpot symbol 1 is forcibly selected, the electric chew support mode 1 is set to the on state, so that the number of continuations is set to (4). Therefore, if it is not determined that the game ball is a big hit by winning the special symbol start port 27 within the period when the electric chew support mode 1 is set to the on state, the game ball is started with the upper special symbol. By winning the mouth 25, it is determined that it is a big hit, and when it is determined that it is a big hit, the probability variation big hit symbol 1 is selected with a high probability, and each of 1B) processing to 6B) is repeated.
2. Description of the Game Loop 2 When it is determined that the game ball is a hit by passing the normal symbol start port 23 in the ON state of the electric chew support mode 2, a win game is performed. The winning game when the electronic chew support mode 2 is on is the same as the winning game when the electric chew support mode 1 is on. Then, there is a high probability that it is determined whether or not the game ball is a big hit by winning a prize at the lower special symbol starting port 27. In the on state of the electric support mode 2, the probability variation mode is set to the on state, and the big hit is determined with a higher jackpot probability than the off state of the probability variation mode.

  When it is determined that the game ball is not a big hit by winning the lower special symbol start opening 27, the special symbol game video is displayed on the lower special symbol display 40, and the number of times of display of the special symbol game video is displayed. It is measured, and it is determined whether or not the measurement result of the display count has reached the set result of the continuation count. In the ON state of the electric support mode 2, the number of times of continuation is set to a value (70) that is significantly closer to the denominator value (100) of the big hit probability (1/100) than in the ON state of the electric support mode 1. Therefore, the probability that it is determined to be a big hit before the measurement result of the number of display times reaches (70) is higher than the probability in the ON state of the electric support mode 1.

If it is determined that the game ball is won by winning the lower special symbol start opening 27, the probability variation big hit symbol 2 from the normal big hit symbol 2 and the probability variation big hit symbol 2 is selected higher than the normal big hit symbol 2 Each of the following 1B ′) processing to 6B ′) processing is performed based on the probability. Accordingly, when it is determined that the game ball is a big hit by winning the lower special symbol starting port 27, the electric chew support mode 2 is set to the ON state again, and the number of continuations is set to (70) again. Therefore, each of the following 1B ′) process to 6B ′) process is repeated, and the measurement result of the number of selections in which either one of probability variation big hit symbol 1 and probability variation big hit symbol 2 is continuously selected as a special symbol is limited. The value (1) is reached.
1B ') The special symbol game video is displayed on the lower special symbol display 40, and the probability variation big hit symbol 2 is stopped and displayed on the special symbol video on the lower special symbol display 40.
2B ') Probability big hit game is performed, and the game ball wins a special winning opening 34 in the probable big hit game, and the game ball is paid out to the player as a prize.
3B ′) The probability variation mode is set to the on state.
4B ′) The electric chew support mode 1 is set to the off state, and the electric chew support mode 2 is set to the on state.
5B ') The number of continuations from when the electronic chew support mode 2 is set to the on state until it is set to the off state is set to (70).
6B ') The number of times that either one of probability variation big hit symbol 1 and probability variation big hit symbol 2 is continuously selected as a special symbol is measured.

When it is determined that the game ball is a big hit by winning the lower special symbol start opening 27 in a state where the measurement result of the number of selections reaches the limit value (1), the normal big hit symbol 2 is forcibly selected. Each of the following 1A ′) processing to 6A ′) processing is performed. When this normal jackpot symbol 2 is selected, there are more game balls than when the normal jackpot symbol 1 is selected, when the probability variable jackpot symbol 1 is selected, and when the probability variable jackpot symbol 2 is selected. Since the big hit game 2 is normally performed so as to allow the player to win the special prize opening 34, the player acquires a larger amount of game balls as prizes than when the game is progressing in the flow of the game loop 1. it can.
1A ′) The special symbol game video is displayed on the lower special symbol display 40, and the normal big hit symbol 2 is stopped and displayed on the special symbol video on the lower special symbol display 40.
2A ′) The normal big hit game 2 is performed, and the game ball is awarded to the special winning opening 34 in the normal big hit game 2, whereby the game ball is paid out to the player as a prize.
3A ′) The probability variation mode is set to the on state.
4A ′) The electric chew support mode 1 is set to the off state, and the electric chew support mode 2 is set to the on state.
5A ′) The number of continuations from when the electronic chew support mode 2 is set to the on state until it is set to the off state is set to (70).
6A ′) The number of selections in which either the probability variation big hit symbol 1 or the probability variation big hit symbol 2 is continuously selected as a special symbol is reset.

When the normal jackpot symbol 2 is forcibly selected, the electric chew support mode 2 is set to the on state, so that the number of continuations is set to (70). Therefore, the probability variation big hit symbol 2 is selected with a high probability by determining that the game ball is a big hit by winning the lower special symbol start opening 27 within the period when the electric support mode 2 is set to the on state. Therefore, each of 1B ′) processing to 6B ′) processing is repeated. That is, in the game loop 2, every time the measurement result of the number of selections in which the probability variation big hit symbol 2 is continuously selected reaches the limit value (1), a lot of game balls are paid out as prizes to the player in the normal big hit game 2. The
3. Promotion from Game Loop 1 to Game Loop 2 When the game ball wins the lower special symbol starting port 27 in the ON state of the electric support mode 1 and is determined to be a big hit, the normal big hit symbol 2 and the probability change One of the jackpot symbols 2 is selected. When the normal jackpot symbol 2 is selected and when the probability variation jackpot symbol 2 is selected, the electric chew support mode 2 is set to the on state, so that the game loop 1 is promoted to the game loop 2 Compared to the game loop 1, it becomes possible to obtain more game balls as prizes.
4). Demotion from Game Loop 2 to Game Loop 1 If the game ball is not determined to be a big hit by winning the lower special symbol start port 27 in the ON state of the electric support mode 2, the electronic support mode 2 Is set to the off state. When both the electric chew support mode 1 and the electric chew support mode 2 are in the off state, the game ball is determined to be a big hit by winning the upper special symbol start opening 25, and either the normal big hit symbol 1 or the probable big hit symbol 1 Is selected. When the normal jackpot symbol 1 is selected and when the probability variation jackpot symbol 1 is selected, the electric chew support mode 1 is set to the on state, so that the game loop 2 is demoted to the game loop 1 It becomes impossible to acquire many game balls as prizes.
[11] Main Processing FIG. 51 is a main processing executed by the CPU 71 of the effect control circuit 70 when the power is turned on. When the power is turned on, the CPU 71 performs register and PIO (parallel input / output port) processing in step S501. Initialize each one. In step S502, the command storage unit 121, the flag storage unit 122, the timer storage unit 123, the counter storage unit 124, and the fixed symbol storage unit 125 of the RAM 73 are initialized, and a timer interrupt is generated every 10 msec in step S503. The CTC (counter / timer) is set as follows.

When the CPU 71 initializes the CTC in step S503, the CPU 71 performs a constant update process in step S504, and the constant value recorded in advance in the ROM 72 as the value of the random counter SR1, the value of the random counter SR2, and the value of the random counter SR3 in the counter storage unit 124. Add the value (1). The values of the random counters SR1 to SR3 are initially set to the lower limit value (0) in step S502. In the counter updating process in step S504, the value of the random counter SR1 is changed from the lower limit value (0) to the upper limit value ( 249) and then cyclically added to the lower limit value (0), and the value of the random counter SR2 is added from the lower limit value (0) to the upper limit value (162) and then returned to the lower limit value (0). The value of 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) to be added cyclically. Each of these lower limit value (0), upper limit value (249), upper limit value (162), and upper limit value (72) is recorded in the ROM 72 in advance.
[12] External Interrupt Processing When each of the upper hold command, the lower hold command, the change start command, the change stop command, the symbol information command, the big hit game start command, and the big hit game stop command is transmitted from the main control circuit 50, the CPU 71 Starts external interrupt processing. The CPU 71 is in an interrupt disabled state by starting the external interrupt processing, and stores each of the upper hold command to the big hit game stop command in the reception command buffer by the external interrupt processing and cancels the interrupt disabled state.
[13] Timer Interrupt Processing FIG. 52 shows timer interrupt processing executed by the CPU 71 every 10 msec when a timer interrupt occurs. The CPU 71 executes command processing at step S511 and pending command processing at step S512 every time a timer interrupt occurs. The decorative symbol game process of S513 and the jackpot game effect process of step S514 are executed in this order.
[13-1] Command Processing The command processing in step S511 of FIG. 52 is performed by the upper hold command, the lower hold command, the change start command, the change stop command, the symbol information command, the jackpot game start command, and the jackpot game stop command in the reception command buffer. It is for determining whether or not each is recorded. When it is determined that an upper hold command is recorded in the reception command buffer, the upper hold command is shifted from the reception command buffer to the command storage unit 121 and received. When it is determined that the lower hold command is recorded in the command buffer, the lower hold command is shifted from the reception command buffer to the command storage unit 121, and when it is determined that the change start command is recorded in the reception command buffer. Command buffer that receives variable start command From the received command buffer to the command storage unit 121, and the symbol information command is received in the received command buffer when it is determined that the changed command is recorded in the received command buffer. When it is determined that the symbol information command is recorded, the symbol information command is shifted from the received command buffer to the command storage unit 121. When it is determined that the jackpot game start command is recorded in the received command buffer, the jackpot game start command is recorded. Is shifted from the received command buffer to the command storage unit 121, and when it is determined that a big hit game stop command is recorded in the received command buffer, the big hit game stop command is shifted from the received command buffer to the command storage unit 121.
[13-2] Hold Command Processing FIG. 53 shows hold command processing in step S512, and the CPU 71 determines whether or not an upper hold command is recorded in the command storage unit 121 in step S521. If it is determined that the upper hold command is recorded in the command storage unit 121, the second byte data of the upper hold command is detected from the command storage unit 121 in step S522, and the game ball is moved to the upper special symbol start port. The number of special symbol games held by winning 25 is detected based on the second byte data detection result. When the detection result of the second byte data is 01h, the number of hold times is detected as one time, and when the detection result of the second byte data is 02h, it is detected as two times. When the detection result of the second byte data is 03h, it is detected as three times, and when the detection result of the second byte data is 04h, it is detected as four times. If the CPU 71 detects the number of suspensions in step S522, the CPU 71 sets the detection result of the number of suspensions to the value of the counter SN1 of the counter storage unit 124 in step S523, and clears the upper suspension command from the command storage unit 121 in step S524.

  If the CPU 71 determines that the upper hold command is not recorded in the command storage unit 121 in step S521, the CPU 71 determines whether or not the lower hold command is recorded in the command storage unit 121 in step S525. If it is determined that the lower hold command is recorded in the command storage unit 121, the second byte data of the lower hold command is detected from the command storage unit 121 in step S526, and the game ball is moved to the lower special symbol starting port. The number of special symbol games held by winning 27 is detected based on the detection result of the second byte data. When the detection result of the second byte data is 01h, the number of hold times is detected as one time, and when the detection result of the second byte data is 02h, it is detected as two times. When the detection result of the second byte data is 03h, it is detected as three times, and when the detection result of the second byte data is 04h, it is detected as four times. If the CPU 71 detects the number of hold times in step S526, the CPU 71 sets the detection result of the number of hold times to the value of the counter SN2 of the counter storage unit 124 in step S527, and clears the lower hold command from the command storage unit 121 in step S528.

  When the CPU 71 clears the upper hold command from the command storage unit 121 in step S524 or clears the lower hold command from the command storage unit 121 in step S528, each of the values of the counter SN1 and the counter SN2 from the counter storage unit 124 in step S529. And the addition result between the detection result of the value of the counter SN1 and the detection result of the value of the counter SN2 is set as the value of the counter SN3 of the counter storage unit 124. In step S530, a pending all erase command is transmitted to the display control circuit 80, and the process proceeds to step S531. The display control circuit 80 erases all the reserved symbols 43 from the reserved area 42 of the decorative symbol display 41 when receiving the reserved all erase command.

  When the CPU 71 proceeds to step S531, it sets a hold display command. This hold display command is set according to the value of the counter SN3 in the counter storage unit 124. When the value of the counter SN3 is (1), the hold display command 1 is set, and the value of the counter SN3 is set. When (2), the hold display command 2 is set, when the value of the counter SN3 is (3), the hold display command 3 is set, and when the value of the counter SN3 is (4) When the hold display command 4 is set, the hold display command 5 is set when the value of the counter SN3 is (5), and when the value of the counter SN3 is (6), the hold display command 6 is set. The hold display command 7 is set when the value of the counter SN3 is (7), and the hold display command 8 is set when the value of the counter SN3 is (8).

When the CPU 71 sets the hold display command in step S531, the CPU 71 transmits the hold display command setting result to the display control circuit 80 in step S532. When receiving the hold display command, the display control circuit 80 detects image data corresponding to the reception result of the hold display command from the VROM, and based on the detection result of the image data in the hold area 42 of the decorative symbol display 41.

When the hold display command 1 is received, one hold symbol 43 is displayed, and when the hold display command 2 is received, two hold symbols are displayed. When the hold display command 3 is received, three hold symbols 43 are displayed, when the hold display command 4 is received, four hold symbols 43 are displayed, and when the hold display command 5 is received, five symbols 43 are displayed. When the hold display command 6 is received, 6 hold symbols 43 are displayed, when the hold display command 7 is received, 7 hold symbols 43 are displayed, and when the hold display command 8 is received, 8 hold symbols 43 are displayed. The reserved symbol 43 is displayed.
[13-3] Decoration Symbol Game Processing FIG. 54 shows the decoration symbol game processing in step S513, and the CPU 71 determines whether or not a change start command is recorded in the command storage unit 121 in step S541. If it is determined that a change start command is recorded in the command storage unit 121, the process proceeds to step S542, and the decorative symbol game flag in the flag storage unit 122 is set to an on state. This decorative symbol game flag is initially set to the off state in step S502. If the CPU 71 sets the decorative symbol game flag in the flag storage unit 122 to the on state in step S542, the decorative symbol in step S543 is displayed. After the game start process, the process proceeds to step S544, and the change start command is cleared from the command storage unit 121.

  In step S545, the CPU 71 determines whether or not the decorative symbol game flag in the flag storage unit 122 is set to the on state. If it is determined that the decorative symbol game flag in the flag storage unit 122 is set to the on state, the process proceeds to step S546, and the constant value ΔT (10 msec) recorded in the ROM 72 in advance is stored in the timer storage unit 123. Add to the value of timer ST1. The value of the timer ST1 is set to the initial value (0) in the decorative symbol game start process in step S543, and the CPU 71 adds the value of the timer ST1 in the timer storage unit 123 in step S546 to thereby add the decorative symbol game. Measure the elapsed time.

When the CPU 71 adds the value of the timer ST1 in the timer storage unit 123 in step S546, the CPU 71 executes the decorative symbol game in the decorative symbol game processing in step S547, and whether the variable stop command is recorded in the command storage unit 121 in step S548. Judge whether or not. If it is determined that a change stop command is recorded in the command storage unit 121, the decorative symbol game flag in the flag storage unit 122 is set to OFF in step S549, and the change from the command storage unit 121 in step S550. The stop command is cleared, and the process proceeds to the decorative symbol game stop process in step S551.
[13-3-1] Decoration Symbol Game Start Process FIG. 55 shows the decoration symbol game start process in step S543, and the CPU 71 detects the second byte data of the change start command from the command storage unit 121 in step S561. In S562, process data corresponding to the detection result of the second byte data is selected from the process data table of FIG. 17, and in step S563, the initial value (0) recorded in advance in the ROM 72 as the value of the timer ST1 in the timer storage unit 123. Set.

  When the CPU 71 initializes the value of the timer ST1 of the timer storage unit 123 in step S563, the CPU 71 selects a video command corresponding to the process data selection result from the video command table of FIG. 19 in step S564, and selects the video command in step S565. The result is transmitted to the display control circuit 80. When the display control circuit 80 receives the selection result of the video command, the display control circuit 80 selects video data for decoration symbol game according to the reception result of the video command from the VROM (see FIG. 20), and displays the selection result of the video data in the VRAM. Expand to.

  When the CPU 71 transmits the selection result of the video command in step S565, the CPU 71 detects the second byte data of the symbol information command from the command storage unit 121 in step S566, and stores the second byte data detection result in the ROM 72 in advance in step S567. The jackpot determination values 02h, 03h, 04h, and 05h recorded are compared. If it is determined that the detection result of the second byte data is the same as one of the big hit determination values 02h to 05h, the decorative symbol is set to the big hit combination in the big hit symbol setting process in step S568, and in step S572 The setting result of the jackpot combination is recorded in the fixed symbol storage unit 125. That is, in the special symbol game, when the normal jackpot symbol 1 (2) is set, when the probability variable jackpot symbol 1 (3) is set, when the normal jackpot symbol 2 (4) is set, and the probability variable jackpot symbol 2 ( In each of the cases where 5) is set, the decorative symbol is set to a jackpot combination.

In step S582, the update result of the value of the random counter SR1 is detected from the counter storage unit 124, and the process proceeds to step S583. Here, a symbol element corresponding to the detection result of the value of the random counter SR1 is selected from the symbol table 1, and the symbol element in the left column, the symbol element in the middle column, and the symbol element in the right column are selected as common symbol elements. Set to. For example, when the detection result of the value of the random counter SR1 is (200), the symbol element (7) is selected, and the symbol element of each column is set to (7), so that the decorative symbol is a combination of jackpots (777). ) And the decorative symbols are recorded in the confirmed symbol storage unit 125 as a jackpot combination (777).

  If the CPU 71 determines in step S567 of FIG. 55 that the detection result of the second byte data of the symbol information command is not one of the big hit determination values 02h to 05h, the detection result of the second byte data of the variation start command in step S569. Is compared with the complete deviation determination value 10h recorded in the ROM 72 in advance. If it is determined that the detection result of the second byte data is different from the complete detachment determination value 10h, the decorative design is set as a combination of detachment reach in the detachment reach setting process in step S570, and in step S572. The setting result of the outreach combination is recorded in the fixed symbol storage unit 125. That is, when the main control circuit 50 selects each of the change start command 8011h, the change start command 8012h, and the change start command 8013h, the decorative symbol is set to the combination of detachment reach.

  FIG. 57 shows the outreach symbol setting process in step S570. The CPU 71 detects the symbol table 1 in FIG. 22A from the ROM 72 in step S591, and the symbol table 2 in FIG. 22B in FIG. 22 from the ROM 72 in step S592. Is detected. In step S593, the update result of the value of the random counter SR1 is detected from the counter storage unit 124. In step S594, the symbol element corresponding to the detection result of the value of the random counter SR1 is selected from the symbol table 1, and the symbol in the left column is selected. Each of the element and the symbol element in the right column is set as a common symbol element selection result. For example, when “SR1 = 200”, the symbol element (7) is selected, and the symbol element in the left column and the symbol element in the right column are respectively set to the common (7).

  When the CPU 71 sets each of the symbol elements in the left column and the right column in step S594, the CPU 71 detects the update result of the value of the random counter SR2 from the counter storage unit 124 in step S595, and stores the middle result from the symbol table 2 in step S596. As the symbol element of the column, one corresponding to the detection result of the value of the random counter SR2 is selected. For example, when “SR2 = 50”, the symbol element (3) is selected.

  When the CPU 71 selects a symbol element in the middle row in step S596, the CPU 71 proceeds to step S597. Here, it is determined whether or not the selection result of the middle row of symbol elements is the same as the setting result of the left row of symbol elements. If it is determined that they are different, the process proceeds to step S599, and the middle row The selection result of the symbol element is set to the symbol element in the middle row. Then, the process proceeds to step 572 in FIG. 55, and the setting results of the symbol elements in the left column, the symbol elements in the middle column, and the symbol elements in the right column are recorded in the confirmed symbol storage unit 125. For example, if the setting result of the symbol element in the left column and the setting result of the symbol element in the right column are (7) and the selection result of the symbol element in the middle column is (3), the symbol element (3) in the middle column Without being changed, the decorative symbol is recorded in the fixed symbol storage unit 125 as a combination of detachment and reach (737).

  When CPU 71 determines in step S597 of FIG. 57 that the selection result of the middle row of design elements is the same as the setting result of the left row of design elements, the selection result of the middle row of design elements is changed to the next design element in step 598. change. In step S599, the change result of the middle row symbol element is set in the middle row symbol element. In step 572 of FIG. 55, the left row symbol element, the middle row symbol element, and the right row symbol element are stored in the confirmed symbol storage unit 125. Record the setting result of each symbol element. For example, if each of the left column symbol element setting result and the middle column symbol element selection result is (8), the middle column symbol element selection result is changed to (1) after (8). Then, the decorative symbol is recorded in the fixed symbol storage unit 125 as a combination of detachment reach (818).

  When the CPU 71 determines in step S569 in FIG. 55 that the detection result of the second byte data of the change start command is the same as the complete disconnection determination value 10h, the combination of the decorative pattern is completely disconnected in the complete disconnection design setting process in step S571. In step S572, the setting result of the completely out of combination is recorded in the confirmed symbol storage unit 125. That is, when the main control circuit 50 selects the change start command 8010h, the decorative symbol is set to a completely out of combination.

  FIG. 58 shows the complete out symbol setting process in step S571. The CPU 71 detects the symbol table 1 in FIG. 22A from the ROM 72 in step S601, and the symbol table 2 in FIG. 22B in FIG. 22 from the ROM 72 in step S602. In step S603, the symbol table 3 shown in FIG. In step S604, the update result of the value of the random counter SR1 is detected from the counter storage unit 124. In step S605, the symbol element corresponding to the detection result of the value of the random counter SR1 is selected from the symbol table 1, and the symbol in the left column is selected. Set to the element.

  When the CPU 71 sets the symbol elements in the left column in step S605, the CPU 71 detects the update result of the value of the random counter SR2 from the counter storage unit 124 in step S606, and the detection result of the value of the random counter SR2 from the symbol table 2 in step S607. The corresponding symbol element is selected and set as the middle row symbol element. In step S608, the update result of the value of the random counter SR3 is detected from the counter storage unit 124, and in step S609, the symbol element in the right column is selected according to the detection result of the value of the random counter SR3 from the symbol table 3. In step S610, the setting result of the symbol element in the left column is compared with the selection result of the symbol element in the right column in step S609.

  If the CPU 71 determines in step S610 that the selection result of the right column symbol element is different from the setting result of the left column symbol element, the selection result of the right column symbol element is set to the right column symbol element in step S612. Then, in step 572 of FIG. 55, the setting results of the symbol elements in the left column, the symbol elements in the middle column, and the symbol elements in the right column are recorded in the confirmed symbol storage unit 125. For example, if the setting result of the symbol element in the left column is (8), the selection result of the symbol element in the right column is (7), and the setting result of the symbol element in the middle column is (1), the symbol element of the right column The selection result (7) is not changed, and the decoration symbol is recorded in the fixed symbol storage unit 125 as a combination (817) in which the decoration symbol is completely off.

  If the CPU 71 determines in step S610 in FIG. 58 that the selection result of the right row symbol element is the same as the setting result of the left row symbol element, the selection result of the right row symbol element is changed to the next symbol element in step S611. change. In step S612, the change result of the right column symbol element is set in the right column symbol element, and in step 572 in FIG. 55, the left column symbol element, the middle column symbol element, and the right column symbol element are set. The result is recorded in the fixed symbol storage unit 125. For example, if the setting result of the symbol element in the left column is (8), the selection result of the symbol element in the right column is (8), and the setting result of the symbol element in the middle column is (1), the symbol element of the right column The selection result is changed to (1) next to (8), and the decoration symbol is recorded in the confirmed symbol storage unit 125 as a combination (811) of complete detachment.

When the confirmed symbol storage unit 125 is set in step S572 of FIG. 55, the CPU 71 transmits a reproduction start command to the display control circuit 80 in step S573, and transmits a hold erase command to the display control circuit 80 in step S574. When the display control circuit 80 receives a playback start command, it starts playback of the selected video data for decoration symbol game developed in the VRAM, and causes the decorative symbol display 41 to respond to the selection result of the video data.

When the probable big hit symbol 1 (3) is stopped and displayed, and when the special big game symbol 2 (4) is stopped and displayed in the special symbol game video on the lower special symbol display 40, and the special special symbol display 40 In the case where the probable big hit symbol 2 (5) is stopped and displayed in the video of the symbol game, the electric chew support mode 2 is reset to the on state when the big hit game ends, and the value of the counter MN1 is set to (70) Is set.

  If the CPU 51 determines in step S712 that the electric chew support flag 2 of the flag storage unit 116 is set to an off state, the CPU 51 sets the electric chew support flag 1 of the flag storage unit 116 to an on state in step S716, and in step S717. The electric chew support flag 2 of the flag storage unit 116 is set to an off state, and (4) for the electric chew support mode 1 is set to the value of the counter MN1 of the counter storage unit 118 in step S718. That is, when both the electric chew support mode 1 and the electric chew support mode 2 are turned off, the special symbol game 1 (2) is stopped and displayed on the upper special symbol display 39 with the special symbol game image and the upper special symbol display. When the probability variation jackpot symbol 1 (3) is stopped and displayed on the device 39 with the special symbol game image, and when the normal jackpot symbol 2 (4) is stopped and displayed on the lower special symbol display 40 with the image of the special symbol game In the case where the probable big hit symbol 2 (5) is stopped and displayed on the lower special symbol display 40 with the video of the special symbol game, the electric support mode 1 is set to the ON state when the big hit game ends, and the counter (4) is set to the value of MN1.

The game flow includes a game loop 1 in which a player can acquire a game ball as a prize in each of the normal jackpot game 1 and the probable big hit game 1, and a player enters the game loop 1 in both the normal jackpot game 2 and the probable big hit game 2 respectively. There are two types of game loops 2 that can acquire more game balls as prizes.
1. Description of the game loop 1 In the on state of the electric chew support mode 1, it is easier for the game ball to win the lower special symbol starting port 27 than in the off state of both the electric chew support mode 1 and the electric chew support mode 2, and the game ball There is a high probability that it is determined whether or not it is a big hit by winning the lower special symbol start opening 27. When it is determined that the game ball wins the upper special symbol start opening 25 in the ON state of the electric chew support mode 1 and it is determined that the game is not a big hit, the special symbol game video is displayed on the upper special symbol display 39, and the game When it is determined that the ball is not a big hit by winning the lower special symbol start opening 27, a special symbol game video is displayed on the lower special symbol display 40. When the special symbol game video is displayed on the upper special symbol display 39 and when the special symbol game video is displayed on the lower special symbol display 40, the number of times the special symbol game video is displayed is measured. Then, it is determined whether or not the display count measurement result has reached the continuation count setting result. In the ON state of the electric support mode 1, the number of continuations is the denominator value (36) of the jackpot probability (1/36) in the off state of the probability variation mode and the jackpot probability (1/35) in the on state of the probability variation mode. ) Is set to a significantly smaller number of times (4) than each denominator value (35), and the probability of the display count measurement result reaching the set number of continuation counts without being determined to be a big hit Is expensive. When the measurement result of the display count reaches the setting result of the continuous count, the electric chew support mode 1 is set to the off state, and both the electric chew support mode 1 and the electric chew support mode 2 are in the probability variation mode on state. Turns off.

In both OFF states of the electronic support mode 1 and the electronic support mode 2, the game ball wins the lower special symbol starting port 27 as compared to the ON state of the electronic support mode 1 and the ON state of the electronic support mode 2. It is difficult to determine whether or not the game ball is a big hit by winning the top special symbol start opening 25. In addition, when it is determined that the game ball is won by winning the special symbol start opening 25, the probability big hit symbol 1 out of the normal big hit symbol 1 and the probability variable big hit symbol 1 is higher than the normal jackpot symbol 1. Each of the following 1B) processing to 6B) processing is performed by selection probability. Accordingly, since the number of continuations is set to (4) again by setting the electronic chew support mode 1 to the on state again, each of the following 1B) processing to 6B) processing is repeated to select the probability variation mode. The measurement result of the number of times reaches the limit value (1).
1B) The special symbol game video is displayed on the upper special symbol display 39, and the probability variation big hit symbol 1 is stopped and displayed on the special symbol video on the upper special symbol display 39.
2B) A probable big hit game is performed, and the game ball wins a special winning opening 34 in the probable big hit game, so that the game ball is paid out to the player as a prize.
3B) The probability variation mode is set to the on state.
4B) The electric chew support mode 1 is set to the on state, and the electric chew support mode 2 is set to the off state.
5B) The number of continuations from when the electronic chew support mode 1 is set to the on state until it is set to the off state is set to (4).
6B) The number of times of selecting the probability variation mode is measured.

When the result of measuring the number of times of selection in the probability variation mode has reached the limit value (1), if it is determined that the game ball is a big hit by winning the upper special symbol start opening 25, the normal big hit symbol 1 is forced. Each of the following 1A) processing to 6A) processing is performed.
1A) The special symbol game video is displayed on the upper special symbol display 39, and the normal big hit symbol 1 is stopped and displayed on the special symbol video on the upper special symbol display 39.
2A) A normal jackpot game 1 is performed, and the game ball is awarded to the special winning opening 34 in the normal jackpot game 1, whereby the game ball is paid out to the player as a prize.
3A) The probability variation mode is set to the off state.
4A) The electric chew support mode 1 is set to the on state, and the electric chew support mode 2 is set to the off state.
5A) The number of continuations from when the electronic chew support mode 1 is set to the on state until it is set to the off state is set to (4).
6A) The number of selections of the probability variation mode is reset.

When the normal jackpot symbol 1 is forcibly selected, the electric chew support mode 1 is set to the on state, so that the number of continuations is set to (4). Therefore, the game ball is not determined to be a big hit by winning a prize in either the upper special symbol starting port 25 or the lower special symbol starting port 27 within the period when the electric chew support mode 1 is set to the on state. In this case, it is determined that the game ball is a big hit by winning the upper special symbol start opening 25. If it is determined that the game is a big hit, the probability variation big hit symbol 1 is selected with a high probability, and 1B) processing to 6B. ) Is repeated.
2. Description of the game loop 2 In the on state of the electric chew support mode 2, the game ball is easy to win the lower special symbol start port 27, and the game ball wins the lower special symbol start port 27 as in the on state of the electric chew support mode 1. Therefore, there is a high probability that it will be determined whether or not it is a big hit. When it is determined that the game ball is not a big hit by winning the upper special symbol starting opening 25 in the ON state of the electric chew support mode 2, the special symbol game video is displayed on the upper special symbol display 39, and the game When it is determined that the ball is not a big hit by winning the lower special symbol start opening 27, a special symbol game video is displayed on the lower special symbol display 40. When the special symbol game video is displayed on the upper special symbol display 39 and when the special symbol game video is displayed on the lower special symbol display 40, the number of times the special symbol game video is displayed is measured. Then, it is determined whether or not the display count measurement result has reached the continuation count setting result. In the ON state of the electric support mode 2, the number of continuations is the denominator value (36) of the jackpot probability (1/36) in the off state of the probability variation mode and the jackpot probability (1/35) in the on state of the probability variation mode. ) Is set to a large number of times (70) compared to each of the denominator values (35), and the probability of being determined to be a big hit before the display number measurement result reaches (70 times) is It is higher than the ON state of support mode 1.

If it is determined that the game ball is a big hit by winning the lower special symbol start opening 27 before the electric chew support mode 2 is switched from the on state to the off state, the normal big hit symbol 2 and the probable big hit symbol 2 Probability big hit symbol 2 is selected with a higher selection probability than normal big hit symbol 2, and each of the following 1B ′) processing to 6B ′) processing is performed. Therefore, if it is determined that the game ball is a big hit by winning the special symbol starting port 27 before the electric chew support mode 2 is switched from the on state to the off state, the electric chew support mode 2 is turned on again. Since the number of continuations is set to (70) again by setting the state, each of the following 1B ′) processing to 6B ′) processing is repeated, and the measurement result of the number of times of selection of the probability variation mode is the limit value ( 1) is reached.
1B ') The special symbol game video is displayed on the lower special symbol display 40, and the probability variation big hit symbol 2 is stopped and displayed on the special symbol video on the lower special symbol display 40.
2B ') Probability big hit game is performed, and the game ball wins a special winning opening 34 in the probable big hit game, and the game ball is paid out to the player as a prize.
3B ′) The probability variation mode is set to the on state.
4B ′) The electric chew support mode 1 is set to the off state, and the electric chew support mode 2 is set to the on state.
5B ') The number of continuations from when the electronic chew support mode 2 is set to the on state until it is set to the off state is set to (70).
6B ′) The number of times of selection of the probability variation mode is measured.

When the result of measuring the number of times of selection in the probability variation mode has reached the limit value (1), when it is determined that the game ball is a big hit by winning the lower special symbol start opening 27, the normal big hit symbol 2 is forced. Each of the following 1A ′) processing to 6A ′) processing is performed. When this normal jackpot symbol 2 is selected, there are more game balls than when the normal jackpot symbol 1 is selected, when the probability variable jackpot symbol 1 is selected, and when the probability variable jackpot symbol 2 is selected. Since the big hit game 2 is normally performed so as to allow the player to win the special prize opening 34, the player acquires a larger amount of game balls as prizes than when the game is progressing in the flow of the game loop 1. it can.
1A ′) The special symbol game video is displayed on the lower special symbol display 40, and the normal big hit symbol 2 is stopped and displayed on the special symbol video on the lower special symbol display 40.
2A ′) The normal big hit game 2 is performed, and the game ball is awarded to the special winning opening 34 in the normal big hit game 2, whereby the game ball is paid out to the player as a prize.
3A ′) The probability variation mode is set to the on state.
4A ′) The electric chew support mode 1 is set to the off state, and the electric chew support mode 2 is set to the on state.
5A ′) The number of continuations from when the electronic chew support mode 2 is set to the on state until it is set to the off state is set to (70).
6A ') The number of times of selection of the probability variation mode is reset.

When the normal jackpot symbol 2 is forcibly selected, the electric chew support mode 2 is set to the on state, so that the number of continuations is set to (70). Therefore, the probability variation big hit symbol 2 is selected with a high probability by determining that the game ball is a big hit by winning the lower special symbol start opening 27 within the period when the electric support mode 2 is set to the on state. Therefore, each of 1B ′) processing to 6B ′) processing is repeated. That is, each time the measurement result of the number of times of selection in the probability variation mode reaches the limit value (1), a lot of game balls are paid out to the player in the normal jackpot game 2.
3. Promotion from Game Loop 1 to Game Loop 2 With the electric chew support mode 1 in the on state, the game ball is determined to be a big hit by winning one of the upper special symbol starting port 25 and the lower special symbol starting port 27. In the case where the electronic chew support mode 2 is turned on, it is set to the on state. For this reason, since the game loop 1 is promoted to the game loop 2, it becomes possible to acquire many game balls as prizes.
4). Relegation from game loop 2 to game loop 1 With the electric chew support mode 2 turned on, the game ball is determined to be a big hit by winning one of the upper special symbol starting port 25 and the lower special symbol starting port 27. If not, the electric chew support mode 2 is set to the off state, and both the electric chew support mode 1 and the electric chew support mode 2 are turned off. When it is determined that the game ball is a big hit by winning a game ball in either the upper special symbol starting port 25 or the lower special symbol starting port 27 in the off state of both the electric chew support mode 1 and the electric chew support mode 2 The electronic support mode 1 is set to the on state. For this reason, since the game loop 2 is demoted to the game loop 1, it becomes impossible to acquire many game balls as prizes.

  In each of the above-described first and second embodiments, the main control circuit 50 operates in both the electric chew support mode 1 and the electric chew support mode 2 in the on state of the electric chew support mode 1 and the on state of the electric chew support mode 2, respectively. A configuration may be adopted in which a hit game is performed so as to allow a large number of game balls to enter the lower special symbol starting port 27 by determining with a high probability that it is a win compared to the off state.

  In each of the first and second embodiments, the main control circuit 50 indicates that both the electric support mode 1 and the electronic support mode 2 are in the ON state of the electronic support mode 1 and the ON state of the electronic support mode 2. The opening time of the lower special symbol start opening 27 is set longer than that of the off state of the electronic chord support mode 1 and the electric chew support mode in the on state of the electric chew support mode 1 and the on state of the electric chew support mode 2, respectively. It is determined with a high hit probability that it is a hit as compared to the OFF state in both modes 2 ”.“ Electrical support mode 1 and electronic test in each of the ON state of electronic support mode 1 and the ON state of electronic support mode 2 ” Time required for normal symbol games compared to both off modes in support mode 2 In the ON state of the electronic support mode 1 and the ON state of the electronic support mode 2 in any one or a combination of two or more of “set short”, the electronic support mode 1 and the electronic support mode 2 A configuration may be adopted in which a game is played so as to allow a larger number of game balls to enter the lower special symbol start port 27 than in both off states.

  In each of the above-described Examples 1 and 2, a gap is provided between the upper special symbol start port 25 and the lower special symbol start port 27 so that a game ball can pass between the upper special symbol start port 27 and the lower special symbol start port 27. A configuration in which a game ball can win a prize through a gap when both the blades 28 are closed may be adopted. That is, the lower special symbol starting port 27 may be switched between a reduced state in which a game ball can win and an expanded state in which the game ball can easily win in comparison with a reduced state.

  In each of the above-described Examples 1 and 2, the big hit probability when the game ball wins the upper special symbol starting port 25 in the probability variation mode on state and the lower special symbol start port in the on state of the probability variation mode When the game ball is won in the upper special symbol starting port 25 in the off state of the jackpot probability and probability variation mode when winning 27, the game ball is in the lower special symbol starting port 27 in the off state of the jackpot probability and probability variation mode when winning. Each of the jackpot probabilities in the case of winning a prize may be set to be equal to or greater than “1 / continuous number of times in support mode 1” and not greater than “1 / continuous number of times in support mode 1”.
