Japanese Patent Laid-Open No. 2000-233051

In the above gaming machine, a plurality of game balls are inserted into the first interlocking accessory device, then into the second interlocking accessory device, and then into the third interlocking accessory device. The linked accessory device can be expanded sequentially. In other words, the profit of the player varies depending on the order in which the game balls enter the plurality of interlocking accessory devices. Since there is a relatively high possibility that the number of prize balls won will differ between a player who is familiar with the game method and a player who is not familiar with the game method, the advantages and disadvantages depending on the skill level of the player will appear significantly. Therefore, there is a problem that it is difficult to improve a beginner's willingness to play. On the other hand, in terms of game play centered on the interlocking of the accessory, there is a problem that the game tends to be monotonous.

It is an object of the present invention to provide a gaming machine that is easy to understand and can be played easily, and that can sometimes change.

The gaming machine according to the present invention has a passage opening through which a game ball passes, a first state in which the game ball is difficult or impossible to win, and a second state in which the game ball is easier to win than the first state. A variable winning opening configured to be variable, a variation control means for changing the variable winning opening from the first state to the second state due to a game ball passing through the passage opening, and the variation A first area and a second area through which the gaming ball that has won the winning opening can pass, and a first starting opening that changes from the first state to the second state when the gaming ball passes through the first area, A second starting port that changes from the first state to the second state when a game ball passes through the second region, and a first movable state that is mutually changeable between the first state and the second state. A second winning hole and a second winning hole, and the first winning hole is changed at least once from the first state to the second state due to a game ball winning the first starting opening. Second winning game, in which the second winning hole is changed at least once from the first state to the second state due to a game ball winning the second starting opening, respectively. An executing means for executing, and a providing means for providing a predetermined profit in response to the game ball winning at least in the first special winning opening and the game ball winning in the second special winning opening, The rate at which the gaming balls that have won the variable winning opening pass through the first area is higher than the rate that the gaming balls that win at the variable winning opening pass through the second area, and the second hit by the executing means. The expected value of the profit given by the giving means when the game is executed is larger than the expected value of the profit given by the giving means when the first hit game is executed by the executing means. Is characterized by.

In the gaming machine according to the present invention, the variable winning opening changes from the first state to the second state due to the game ball passing through the passage opening. When the game ball that has won the variable winning opening passes through the first area, the first starting opening changes from the first state to the second state. When the game ball that has won the variable winning opening passes through the second area, the second starting opening changes from the first state to the second state. Due to the game ball winning the first starting opening, the first winning game in which the first big winning opening changes from the first state to the second state at least once is executed. Due to the game ball winning the second starting opening, the second winning game in which the second special winning opening changes from the first state to the second state at least once is executed. Predetermined profit is awarded in response to the game ball winning the first winning opening and the game ball winning the second major winning opening. Here, the rate at which the gaming balls that have won the variable winning opening pass through the first area is higher than the rate at which the gaming ball passes through the second area. Therefore, the frequency at which the first starting opening changes from the first state to the second state due to the gaming ball winning the variable winning opening is due to the gaming ball winning the variable winning opening The frequency at which the second starting port changes from the first state to the second state is higher. Therefore, in a normal game, the first hit game is more likely to be executed than the second hit game because the game ball passes through the passage opening. On the other hand, when the second winning game is executed, the expected value of the profit to be given is larger than when the first winning game is executed. Therefore, the player usually enjoys the first winning game and sometimes enjoys the second winning game, which causes a change in the game. Also, by allowing the game ball to win at the variable starting port that is opened due to passing the game ball through the passage port, the first starting port or the second starting port that opens when a prize is awarded to the variable starting port. Since the first win game or the second win game is executed, the game procedure is clear. Therefore, the gaming machine according to the present invention can provide a gaming property that is easy to understand and can be played easily, and can be changed at times.

The gaming machine has a first random number acquisition means for acquiring a first random number when the game ball wins the first starting opening, and a second random number when the game ball wins the second starting opening. Second random number acquisition means for acquiring a random number, first determination means for determining whether to execute the first winning game based on the first random number acquired by the first random number acquisition means, and the second random number A second determination means for determining whether to execute the second winning game may be provided based on the second random number acquired by the acquisition means. The executing means may execute the first winning game according to the result of the determination by the first determining means, and the second winning game according to the result of the determination by the second determining means. The probability that the first determining means determines to execute the first winning game may be higher than the probability that the second determining means determines to execute the second winning game.

In this case, the determination by the first determination means is performed based on the first random number, and the determination by the second determination means is performed based on the second random number. Therefore, the gaming machine is capable of performing the first winning game and the second winning game. Easy to control the probability of execution. Since the first winning game is executed with a higher probability than the second winning game, it is possible for the player to easily continue the game even when the second winning game is difficult to execute.

The first hit game may include a small hit game and a first big hit game. The second winning game may include a second jackpot game in which the expected value of the profit given by the giving means is larger than that in the first jackpot game. The probability that the small hit game is executed due to the game ball winning in the first starting opening is the probability that the game ball is executed in the first starting opening due to the game ball winning in the first starting opening. It may be higher than the probability.

In this case, the small hit game is executed with a higher probability than the probability that the first big hit game is executed due to the game ball winning the first starting opening. Therefore, in the normal game, even if the first big hit game is not easily executed, the profit from the small hit game that is executed more frequently than the first big hit game is given, so the player continues the game. It's easy to do.

The second special winning opening may be provided with a specific area through which a game ball winning the second special winning opening can pass. The executing means may execute the second jackpot game on the condition that the game ball winning the second special winning opening passes through the specific area.

In this case, a specific area through which the winning game ball can pass is provided in the second special winning opening, and the game ball winning in the second special winning opening is in a specific area in response to the execution of the second winning game. Can pass through. When the game ball makes a specific area, the second jackpot game is executed. That is, in the gaming machine, a so-called blade-type game is executed due to the winning of the game ball into the second starting opening. Therefore, the gaming machine can allow the player to easily enjoy the game according to the playability of the feather type.

In the present embodiment, the condition device operates when the special symbol indicating the big hit is confirmed and displayed. Further, the accessory continuous operation device is a device for causing a big hit game state in which the special winning opening is continuously operated. Hereinafter, the state in which the condition device and the accessory continuous operation device are operating is referred to as a jackpot gaming state.

In this embodiment, when the game ball wins the first starting opening 12, the first jackpot determination is performed, the first special symbol indicating the result of the determination is displayed in the first special symbol display portion of the symbol display portion 24. It Moreover, when the game ball wins the second starting opening 13, the second jackpot determination is performed, the second special symbol indicating the result of the determination is displayed on the second special symbol display portion of the symbol display portion 24. In the first jackpot determination, whether the jackpot, the jackpot, or the out-of-between is determined based on the jackpot random number. In the second jackpot determination, whether the jackpot or the jackpot is determined based on the jackpot random number.

When it is determined to be a big hit in the first big hit determination, the first special symbol indicating that the determination result is a big hit is definitely displayed on the first special symbol display part of the symbol display part 24, and the condition device operates. .. When the condition device operates, the accessory continuous operation device operates to generate a jackpot game state, and the jackpot game in which the opening/closing member 161 of the first special winning opening 16 is repeatedly opened a predetermined number of times in a predetermined opening pattern is executed. It When it is determined that it is a big hit in the second big hit determination, the second special symbol indicating that the determination result is a big hit is definitely displayed on the second special symbol display part of the symbol display part 24, and the condition device operates. .. When the condition device operates, the accessory continuous operation device operates to generate a jackpot game state, and the jackpot game in which the opening/closing member 171 of the second special winning opening 17 is repeatedly opened a predetermined number of times in a predetermined opening pattern is executed. It

The small hit game will be described. When it is determined that it is a small hit in the first big hit determination, the first special symbol indicating that the determination result is a small hit is confirmed and displayed on the first special symbol display portion of the symbol display portion 24. After the special symbol indicating that it is a small hit is confirmed and displayed on the symbol display section 24, the small hit game in which the opening/closing member 161 of the first special winning opening 16 is opened for a predetermined time in a predetermined opening pattern is executed. In the present embodiment, the opening/closing member 161 of the first special winning opening 16 is opened once for a predetermined time in the small hit game. The small hit game is generally a game that has a smaller advantage for the player than the big hit game. At the time when the determination result of the big hit determination is a small hit, the condition device does not operate, so that the accessory continuous operation device also does not operate. Therefore, in the small hitting game of the present embodiment, the opening/closing member 161 of the first special winning opening 16 and the opening/closing member 171 of the second special winning opening 17 are not repeatedly opened a predetermined number of times.

The storage area is provided with an ordinary hit random number column in which the value of the ordinary hit determination counter is stored, and an ordinary symbol determination random number column in which the value of the ordinary symbol determination counter is stored. The normal hit random number is used for the normal hit determination. Ordinary symbol determination random numbers are normally used to determine the winning symbol. Various random numbers acquired together with the ordinary hit random numbers and stored in the ordinary hit related information storage area are collectively referred to as ordinary random numbers. The variation time of the normal symbol is a predetermined time (for example, 3 seconds) that is set in advance. A plurality of variable times of the normal symbol may be defined.

With reference to FIG. 7, an opening pattern of the opening/closing member 111 of the power tube 11 and an operation pattern of the distribution shutter 195 will be described. The opening/closing member 111 of the electric chew 11 performs an opening/closing operation related to a normal hit game in an opening pattern according to the normal hit type. When a predetermined number (one in the present embodiment) of game balls is won in the electric chute 11 with the opening/closing member 111 opened, the opening/closing operation of the opening/closing member 111 is performed even during the opening/closing operation according to each opening pattern. After that, the opening/closing member 111 is closed. This predetermined number may be an arbitrary number of 2 or more.

The distribution shutter 195 operates in a predetermined distribution shutter operation pattern. In the distribution shutter operation pattern, when the normal hit game is executed, the distribution shutter 195 moves from the first position D1 to the second position between time T0 and time T1, which is the start time of the normal hit game. It is located at D2. Next, the distribution shutter 195 is arranged at the first position D1 from the time T1 to the time T3 when the time TB has elapsed. Next, the distribution shutter 195 is arranged at the second position D2 from the time T3 to the time T9 when the time TC has elapsed. After that, the distribution shutter 195 is arranged at the first position D1 from the time point T9 to the time point T10 which is the time when the normal winning game ends.

The opening/closing operation of the electric chew 11 relating to the normal hit game is performed in an opening pattern of either the first pattern P1 or the second pattern P2. In the first pattern P1, the opening/closing member 111 of the power tube 11 is kept open from the time T0 until the time TD elapses. At time T2 when the time TD has elapsed from time T0, the opening/closing member 111 of the power tube 11 is closed. After that, the opening/closing member 111 of the power tube 11 is maintained in the closed state from time T2 to time T10. That is, in the first pattern P1, the opening/closing member 111 of the power cable 11 is opened once at the time TD.

The time TD in the first pattern P1 is 2.0 seconds. Therefore, when the opening/closing member 111 of the electric chew 11 is opened/closed in the first pattern P1, the game ball can be won in the electric chew 11 between time T0 and time T2. In addition, at any other timing, the game ball does not win the electric ball 11. During the time TD, the time during which the distribution shutter 195 is arranged at the first position D1 is longer than the time during which it is arranged at the second position D2. It is time TA (0.040 seconds) that the distribution shutter 195 is arranged at the second position D2 during the time TD. Therefore, of the game balls that enter the electric circuit 11 opened in the first pattern P1 and flow down the flow path 191 of the distribution flow path 19, there are almost no game balls that are guided to the second flow path 191B. Therefore, most of the game balls that enter the electric Chu 11 opened in the first pattern P1 and flow down the flow passage 191 of the distribution flow passage 19 are guided to the first flow passage 191A and pass through the first passage area 192. It's easy to do. When the game ball passes through the first passage area 192, the first actuation mechanism operates and the opening/closing member 121 of the first starting opening 12 is opened. Therefore, when the power switch is opened in the first pattern P1, the opening/closing member 121 of the first starting opening 12 is more likely to be opened than the opening/closing member 131 of the second starting opening 13. In the present embodiment, the time TE from the time T2 when the distribution shutter 195 is arranged at the first position D1 to the time T3 when the distribution shutter 195 is arranged at the second position D2 is 1. 0 seconds. Therefore, the game ball that has won the electric power chute 11 immediately before the time point T2 is easily guided to the first flow path 191A during the time TE and easily passes through the first passage area 192.

On the other hand, in the second pattern P2, the opening/closing member 111 of the electric tube 11 is kept open from the time T0 until the time TA elapses. After that, the opening/closing member 111 of the power tube 11 is closed until the time TB elapses from the time T1. Next, at time T3 when time TB elapses from time T1 until the time TF elapses from time T3, the opening/closing member 111 of the power tube 11 is opened. Next, at time T4 when time TF elapses from time T3, the opening/closing member 111 of the electric tube 11 is closed until time T5 when time TG elapses. Next, from time T5 to time T6 when time TF elapses, the opening/closing member 111 of the power tube 11 is opened. Next, from time T6 to time T7 when the time TG has elapsed, the opening/closing member 111 of the power tube 11 is closed. Next, from time T7 to time T8 when the time TF has elapsed, the opening/closing member 111 of the power tube 11 is opened. After that, from time T8 to time T10, the opening/closing member 111 of the power tube 11 is maintained in the closed state. That is, in the second pattern P2, after the opening/closing member 111 of the power tube 11 is opened once at the time TA, it is opened three times at the time TF with the closing of the time TB.

In this embodiment, the time TF is 0.8 seconds. Therefore, when the opening/closing member 111 of the electric chew 11 is opened/closed in the second pattern P2, the game ball can be won in the electric chew 11 during the time TF. The distribution shutter 195 is arranged at the second position D2 while the opening/closing member 111 of the power tube 11 repeats the open state of the time TF three times from the time T3. For this reason, the game ball that has won the electric chew 11 at the timing from the time point T3 to the time point T8 is easily guided to the second flow path 191B and easily passes through the second passage area 193. When the game ball passes through the second passage area 193, the second actuation mechanism operates and the opening/closing member 131 of the second starting opening 13 is opened. Therefore, when the power switch is opened in the second pattern P2, the opening/closing member 131 of the second starting opening 13 is more likely to be opened than the opening/closing member 121 of the first starting opening 12. In the present embodiment, the time TC during which the distribution shutter 195 is arranged at the second position D2 continues between the time points T8 and T9. Therefore, the gaming ball that has won the electric power chute 11 immediately before the time point T8 is easily guided to the second flow path 191B while TC continues and easily passes through the second passage area 193. Hereinafter, the first pattern P1 and the second pattern P2, which are the opening patterns of the opening/closing member 111 of the power tube 11, are collectively referred to as the power channel opening pattern.

The normal symbol determination table stored in the ROM 53 will be described with reference to FIG. The pachinko machine 1 determines an ordinary hit symbol indicating that the result of the ordinary hit determination is an ordinary hit by referring to the ordinary symbol determination table. Ordinary winning design is classified into one of the ordinary winning types of "1 ordinary hit" and "2 ordinary hits". In the normal symbol determination table, the value of the normal symbol determination random number (0 to 99) is associated with each of the ordinary hit types. The value of the ordinary symbol determination random number is assigned to each ordinary hit type so that “ordinary 1” is 85% and “ordinary 2” is 15%.

An electric chew opening pattern is associated with each ordinary hit type. The "normal hit 1" is associated with the first pattern P1, and the "normal hit 2" is associated with the second pattern P2. That is, in the case where it is determined to be a normal hit by the normal hit determination, if the normal hit type determined in accordance with the normal hit determination is "normal hit 1", the normal hit game according to the first pattern P1 is executed. Further, in the case where it is determined to be a normal hit by the normal hit determination, if the normal hit type determined in accordance with the normal hit determination is "normal hit 2", the normal hit game according to the second pattern P2 is executed.

The first pattern P1 is an electric chew opening pattern in which the game ball is more likely to pass through the first passing area 192 than the second passing area 193. The second pattern P2 is an open pattern in which the game ball passes through the second passage area 193 more easily than the first passage area 192. When it is determined by the normal hit determination that the hit is a normal hit, the "normal hit 1" is determined at 85% and the "normal hit 2" is determined at 15%. Therefore, in the normal hit game, the percentage of the game balls that win the Den Chu 11 passing through the first passing area 192 is about 85%, and the game balls that win the Den Chu 11 in the normal hit game pass the second passing area 193. The passing rate is about 15%. That is, when the normal winning game is executed, the ratio of the gaming balls that have won the electric Chu 11 passing through the first passing area 192 is the ratio of the gaming balls that have won the electric Chu 11 passing through the second passing area 193. Will be higher than.

When the game ball passes through the first passage area 192, the first actuation mechanism operates and the opening/closing member 121 of the first starting opening 12 is opened. When the game ball passes through the second passage area 193, the second actuation mechanism operates and the opening/closing member 131 of the second starting opening 13 is opened. Therefore, when the normal hit game is executed in the first pattern P1, the game ball is easier to win in the first starting opening 12 than in the second starting opening 13. When the normal hit game is executed in the second pattern P2, the game ball is easier to win in the second starting opening 13 than in the first starting opening 12. Therefore, when the normal hit game is executed in the first pattern P1, the first jackpot determination is easier to perform than the second jackpot determination. When the normal hit game is executed in the second pattern P2, the second jackpot determination is easier to perform than the first jackpot determination.

With the above configuration, in the pachinko machine 1, when the game ball wins the electric Chu 11 in the normal win game, the first jackpot judgment is about 85%, and the second jackpot judgment is about 15%, respectively. To be executed. In other words, when the normal hit game is executed when the game ball passes through the normal symbol operation gate 10, the first big hit determination is mainly executed in the normal game, but sometimes, the second big hit. The judgment may be executed. As described above, in the pachinko machine 1, the frequency of performing the second jackpot determination is set to be lower than the frequency of performing the first jackpot determination.

The special symbol determination table stored in the ROM 53 will be described with reference to FIG. The pachinko machine 1, the first special symbol indicating that the result of the first jackpot determination is a big hit or a small hit, and the second special symbol indicating that the result of the second jackpot determination is a jackpot, the special symbol determination table It is decided by referring to. The first special symbol and the second special symbol are classified into any one of the hit types. The hit type of the first special symbol includes a jackpot type indicating that the result of the jackpot determination is a jackpot, and a jackpot type indicating that the result of the jackpot determination is a jackpot. The hit type of the second special symbol includes a jackpot type indicating that the result of the jackpot determination is a jackpot.

In the special symbol determination table, a value (0 to 99) of the special symbol determination random number is associated with each of the plurality of winning types. In the present embodiment, when it is determined that the jackpot is the jackpot, the jackpot type “16R jackpot A” is determined at a rate of 100%. If the first big hit determination determines that the small hit is a small hit, the small hit type of “small hit A” is determined at a rate of 100%. When it is determined that the jackpot is the jackpot, the jackpot type of “16R jackpot B” is determined at a rate of 100%. However, the present invention is not limited to this, and the first special symbol and the second special symbol may include a plurality of types of big hits and small hits.

"16R" in the jackpot type indicates the number of rounds associated with the jackpot type. The number of rounds is the total number of big hit rounds that constitute one big hit game. The big hit round is a repeating unit in which the opening/closing member 161 of the first big winning opening 16 or the opening/closing member 171 of the second big winning opening 17 is continuously opened. In the following, the number of rounds may be indicated as “R”. “16R” in the jackpot type indicates that the number of rounds is “16”.

The special symbol determination table defines an opening pattern of the first big winning opening 16 and the second big winning opening 17 corresponding to each winning type. In the present embodiment, in the jackpot type “16R jackpot A”, it is defined that the first jackpot 16 is opened once for a maximum of 0.8 seconds in all jackpot rounds. Further, in the jackpot type of “16R small hit B”, it is defined that the second special winning opening 17 opens once for a maximum of 28.0 seconds once in all big hit rounds. Further, in the small hit type of “small hit A”, the first special winning opening 16 is defined to be opened once for a maximum of 1.0 seconds. Hereinafter, the maximum opening time of the first special winning opening 16 in one big hit round corresponding to the big hit type of "16R big hit A" is also referred to as a first opening time. Below, the maximum opening time of the second special winning opening 17 in one big hit round corresponding to the big hit type of "16R big hit B" is also called the second opening time. Below, the opening time of the 1st special winning opening 16 corresponding to the small hit type of "small hit A" is also called the 3rd opening time below.

In this embodiment, when three or more game balls are won in the first big winning opening 16, the first big winning opening 16 is opened even if the first opening time or the third opening time has not passed. finish. Hereinafter, the number of winning prizes at which the first big winning opening 16 finishes opening even if the first opening time or the third opening time has not elapsed is also referred to as a first winning possible number. Further, when 10 or more game balls are won in the second special winning opening 17, the second special winning opening 17 ends the opening even if the second opening time has not elapsed. The number of winning prizes at which the second special winning opening 17 finishes opening even if the second opening time has not elapsed is also referred to as a second winning possible number below.

As described above, in the present embodiment, “16R jackpot A” and “16R jackpot B” have the same number of rounds, but different maximum opening times in one jackpot round. The second opening time is set longer than the first opening time. Therefore, in the jackpot game corresponding to "16R jackpot B" having a longer maximum opening time, the number of game balls winning the second jackpot 17 is the first jackpot prize in the jackpot game corresponding to "16R jackpot B". It is larger than the number of game balls that win the mouth 16. Further, in the pachinko machine 1, the number of prize balls per game ball to win the second prize hole 17 is made larger than the number of prize balls per game ball to win the first prize hole 16. There is. In this embodiment, when one game ball is won in the first big winning opening 16, three game balls are paid out as prize balls. When one game ball wins the second big winning opening, 15 game balls are paid out as a prize ball. Therefore, the expected value of the total number of prize balls paid out when the jackpot game corresponding to "16R jackpot B" is executed is the prize ball paid out when the jackpot game corresponding to "16R jackpot A" is executed. Will be larger than expected for the total number of. Here, in the pachinko machine 1, the first jackpot determination is executed due to the winning of the first starting opening 12, and the second jackpot determination is executed due to the winning of the second starting opening 13. Therefore, the expected value of the profit given to the player when the jackpot game is executed as the result of the second jackpot determination is given to the player when the jackpot game is executed as the result of the first jackpot determination. Greater than expected profit.

In the present embodiment, the game ball launching device 37 shoots one game ball every 0.6 seconds, so that the game is released in the first opening time in the jackpot game corresponding to "16R jackpot A". The number of game balls to be won in the one big winning hole 16 is, for example, about one. Therefore, the number of prize balls (A1) paid out to the player by executing the jackpot game corresponding to “16R jackpot A” once according to the determination result of the first jackpot determination is about 48 at maximum. .. In addition, in the big hit game corresponding to "16R big hit B", about 10 game balls corresponding to the second possible winning number are won in the second special winning opening 17 opened in the second opening time. Therefore, the number of prize balls (A2) paid out to the player by executing the jackpot game corresponding to "16R jackpot B" once according to the determination result of the second jackpot determination is about 2400.

In addition, when the first jackpot determination is performed and the determination result of the small hit is obtained, the small jackpot game is executed and the first big winning opening 16 is opened in the third opening time. In the present embodiment, the third opening time is shorter than the second opening time. In addition, in the present embodiment, one game ball is shot by the game ball launching device 37 every 0.6 seconds, so the first big winning opening 16 that is opened in the third opening time in the small hit game is won. The number of game balls to play is, for example, about 1 to 2. Therefore, the number of prize balls (B1) paid out to the player by executing the small hit game once according to the determination result of the first big hit determination is about 6 at maximum.

The expected value of the total number of prize balls to be paid out according to the determination result of the first jackpot judgment when the game balls are won in the electric Chu 11 is A1, B1, the jackpot probability (1/50), the first small prize The following values are calculated based on the hit probability (40/50) and the execution ratio of the first big hit judgment and the second big hit judgment.
((Probability of big hit)×A1+(probability of first small hit)×B1)×0.85=4.1616

In addition, the expected value of the total number of prize balls to be paid out according to the determination result by the second jackpot determination when the game ball is won in the electric Chu 11 is A2, the jackpot probability (1/50), and the first jackpot determination. When calculated based on the execution ratio with the second jackpot determination, the following values are obtained.
(Big hit probability)×A2×0.15=7.2

As described above, in the pachinko machine 1, the expected value of the profit given to the player according to the determination result of the second jackpot determination is the expected value of the profit given to the player according to the determination result of the first jackpot determination. It is greater than the value.

Therefore, the player plays the game with the aim of performing the second jackpot determination rather than the first jackpot determination. Therefore, the player pays attention to which electric chute opening pattern the normal hit game is executed when the game ball passes through the normal symbol actuation gate 10, and the normal symbol actuation gate 10 is left-handed. Continue the game while firing a game ball toward. In addition, the game is continued while paying attention to which of the first starting opening 12 and the second starting opening 13 is opened, when the game ball wins the opened electric ball 11. In the present embodiment, as defined in the normal symbol determination table (see FIG. 8), the rate at which the normal hit game is executed in the first pattern P1 is the rate at which the normal hit game is executed in the second pattern P2. Higher than.

Therefore, in the normal game, the player uses the small hit game executed as the result of the first big hit judgment or the prize ball of the "16R big hit A" big hit game as a base (holding ball) for continuing the game. While gaining as, slowly proceed with the game. In the first jackpot determination, the first jackpot probability is set higher than the jackpot probability. Therefore, as a result of the determination by the first big hit determination, since the small hit game is executed more frequently than the big hit game, the player can easily continue the game while obtaining a prize ball based on the small hit game as a base. During this time, the player can proceed with the game by continuing to shoot the game ball toward the normal symbol operation gate 10. Further, when the accessory such as the electric Chu 11, the first starting opening 12, the second starting opening 13, the first big winning opening 16 and the second big winning opening 17 is opened, the player aims at the opened opening. You just have to shoot a game ball. Since the game procedure is simple in this way, the player can easily play the pachinko machine 1. Then, when the electric Chu 11 is opened in the second pattern P2 in the normal hit game, and when the jackpot game of "16R jackpot B" is executed as a result of the second jackpot judgment, many prize balls are awarded as special prizes. Is given to the player. In other words, the pachinko machine 1 usually realizes a game specification such as a so-called ordinary machine, in which a simple and little change game is advanced to the player while a jackpot game in which many prize balls are occasionally paid out is generated. ing.

In this way, the player usually proceeds with the game slowly while watching the electric-chu open pattern in the normal hit game, and when the "16R jackpot B" jackpot game is executed, many prize balls are obtained. You can enjoy the changes that can be obtained. In the present embodiment, the second big winning opening 17 which is opened in the big hit game of "16R big hit B" is arranged at a position where the right-handed game ball can win. Therefore, as the jackpot game of "16R jackpot B" is executed, a change in the game such as switching the firing intensity of the game ball from left hitting to right hitting occurs.

The special symbol variation pattern determination table stored in the ROM 53 will be described with reference to FIG. The special symbol variation pattern determination table is provided with a plurality of tables depending on whether the big hit judgment is the first big hit judgment or the second big hit judgment. When the big hit determination is the first big hit determination, a plurality of types of variation patterns are assigned according to the result of the big hit determination (big hit, small hit or off). When the big hit determination is the second big hit determination, a plurality of types of variation patterns are assigned according to the result of the big hit determination (big hit or miss). The value (0 to 511) of the fluctuation pattern determination random number is associated with each fluctuation pattern. When the jackpot determination is performed, a table corresponding to the determination result is referred to, and one variation pattern corresponding to the value of the variation pattern determination random number acquired together with the jackpot random number is determined.

As shown in FIG. 10, when the determination result by the jackpot determination is a jackpot or a jackpot, any one of the plurality of variation patterns is determined according to the value of the variation pattern determination random number. Different fluctuation times are associated with each of the plurality of fluctuation patterns. In this case, after the game ball wins the first starting opening 12 or the second starting opening 13, the first big winning opening 16 or the second big winning opening in the jackpot game or the small hitting game depending on the result of the jackpot judgment. There are multiple times until the opening of 17 is started. Therefore, the pachinko machine 1 suppresses aiming by the player to the first big winning opening 16 or the second big winning opening 17 using the timing when the game ball wins the first starting opening 12 or the second starting opening 13. be able to.

The operation of the main board 41 of the pachinko machine 1 will be described with reference to FIGS. 11 to 20. Main control of the pachinko machine 1 is performed by a control program stored in the ROM 53. The main processing of the control program (see FIG. 11) is executed by the CPU 51 when the CPU 51 senses an interrupt signal generated by the interrupt signal generating circuit 57 (see FIG. 5) every 4 ms. Hereinafter, each step of the flowchart is abbreviated as "S".

As shown in FIG. 11, when the main process is started, first, a command output process is performed (S10). In the command output process, the control command is output to the sub control board 58, the payout control board 45, the relay board 47, and the like. The control command output here is the control command stored in the RAM 52 in the main process.

Next, a switch reading process is performed (S11). In the switch reading process, each of the switches provided in the normal symbol actuation gate 10, the electric Chu 11, the first starting opening 12, the second starting opening 13, the first big winning opening 16, the second big winning opening 17, and other winning openings. From the detection result (see FIG. 5), processing for detecting a game ball is performed.

Next, counter updating processing is performed (S12). In the counter updating process, the value of the random number acquisition counter stored in the RAM 52 is added, and the value of the special symbol fluctuation time counter, which is a timer counter for measuring the fluctuation time of the special symbol, is subtracted.

Next, the special electric accessory processing is performed (S13). Although details will be described later, in the special electric auditors product processing, processing for controlling the operation of the big hit game and the small hit game is performed (see FIGS. 18 to 20). The operations of the big hit game and the small hit game are mainly opening/closing operations of the opening/closing member 161 of the first big winning opening 16 and the opening/closing member 171 of the second big winning opening 17.

Next, special symbol processing is performed (S14). Although details will be described later, in the special symbol process, a big hit determination, a determination of a variation pattern, a determination process of a special symbol, and the like are performed (see FIGS. 15 to 17).

Next, the normal electric accessory processing is performed (S15). Although details will be described later, in the normal electric auditors product processing, processing for controlling the operation of the normal hit game is performed. The operation of the normal hit game is mainly the opening/closing operation of the opening/closing member 111 of the electric chew 11 (see FIG. 14).

Next, normal symbol processing is performed (S16). Although details will be described later, in the normal symbol processing, processing such as normal hit determination, determination of a normal symbol, and determination of an electric chew opening pattern is performed (see FIGS. 12 and 13).

Next, a payout process (S17), an error check (S18) and an information output process (S19) are performed. In the payout process, payout of prize balls is controlled. In the error check, when an error has occurred, the error is notified using the speaker 48 or the like. In the information output processing, various kinds of information are output to a game hall management computer (not shown).

Details of the normal symbol processing (S16, see FIG. 11) will be described with reference to FIGS. 12 and 13. First, the flag used in the normal symbol processing will be described. The RAM 52 stores a normal hit game status flag, a normal symbol display status flag, a power-chu open pattern flag, and the like.

The normal hitting game flag is a flag indicating whether the normal hitting game is in progress, "1" is stored during the normal hitting game and becomes "ON", and "0" is stored when the normal hitting game is not in progress. Is turned off. The normal symbol display state flag is stored as "1" when the normal symbol is fluctuating (during fluctuation) and becomes "ON", and is "2" when the normal symbol is stopped and displayed (during stop display). , "0" is stored when the normal symbol is neither changing nor in stop display.

As shown in FIG. 12, when the normal symbol processing is started, it is determined whether or not the game ball has passed through the normal symbol operating gate 10 (S41). When the gate switch 75 detects the passage of the game ball, the flag corresponding to the gate switch 75 is turned “ON” in the switch reading process of the main process (S11, see FIG. 11). If this flag is not "ON", it is determined that the game ball has not passed through the normal symbol operation gate 10 (S41: NO), and the process proceeds to the determination of S51. If the game ball has passed through the normal symbol operation gate 10 (S41: YES), it is determined whether the number of normally reserved balls is "4" (S43). If the number of ordinary reserved balls stored in the storage area of the ordinary hit relation information is "4" (S43: YES), the number of storable ordinary reserved balls has reached the upper limit, so the process proceeds to S51. To do.

When the number of normally reserved balls is not "4" (S43: NO), "1" is added to the number of normally reserved balls stored in the storage area of the normal hit relation information (S45). Next, the normal hit random number is acquired and stored in the storage area having the smallest number among the empty storage areas in the normal hit related information storage area (S46). The processing shifts to the determination of S51.

Next, it is determined whether or not the normal hit game is being played (S51). When the normal hit game flag is "ON", it is determined that the normal hit game is being played (S51: YES), and the process returns to the main process. When the normal hit game flag is "OFF", it is determined that the normal hit game is not in progress (S51: NO), and it is determined whether the normal symbol is changing (S52). If the normal symbol display state flag is not "1", it is determined that the normal symbol is not changing (S52: NO), it is determined whether the normal symbol is in the stopped state (S53). If the normal symbol display state flag is not "2", it is determined that the normal symbol is not in the stopped state (S53: NO), the process proceeds to S61 (see FIG. 13), and a process such as a normal hit determination is performed.

Next, as shown in FIG. 13, it is determined whether the number of normally reserved balls is “1” or more (S61). When the number of normally reserved balls stored in the storage area for the ordinary hit relation information is "0" (S61: NO), the process returns to the main process. When the number of ordinary reserved balls is equal to or more than "1" (S61: YES), the number of ordinary reserved balls stored in the storage area for the ordinary hit relation information is subtracted by "1" (S62). Next, the determination area of the normal hit relation information is shifted to the storage area of the next number (S63).

Next, the normal hit determination is performed (S65). Although not shown, the ROM 53 stores a normal hit determination table for making a normal hit determination. In the ordinary hit determination table, random number values of ordinary hit random numbers respectively corresponding to “ordinary hit” and “off” are defined. In S65, the ordinary hit determination table is referred to, and it is determined whether the ordinary hit random number stored in the determination area shifted in S63 corresponds to "ordinary hit" or "off." As a result, the ordinary hit determination based on the undetermined ordinary hit random numbers stored in the RAM 52 is performed in the order in which the ordinary hit random numbers are stored.

Next, it is determined whether the determination result of the normal hit determination is a normal hit (S66). When the determination result of the normal hit determination is out (S66: NO), a predetermined ordinary symbol indicating that the determination result of the normal hit determination is out is determined (S76), and the process proceeds to S77. If the result of the normal win determination is normal win (S66: YES), the normal win type of the normal win symbol is determined (S71). In the process of S71, the normal symbol determination table (see FIG. 8) is referred to, and the normal hit corresponding to the value of the normal symbol random number acquired at the same time as the ordinary hit random number stored in the determination area shifted in S63 The type is determined.

Next, the normal symbol determination table is referred to, and the electric-chu open pattern corresponding to the normal hit type determined in the process of S71 is specified (S73). The electric cable opening pattern specified from either the first pattern P1 or the second pattern P2 is stored in the RAM 52 (S75).

Then, the variation time of the normal symbol is stored in the normal symbol variation time counter (S77). Normally, "1" indicating that the symbol is changing is stored in the regular symbol display state flag (S78), and the process returns to the main process.

Further, in the determination of S52 shown in FIG. 12, when "1" is stored in the normal symbol display state flag, it is determined that the normal symbol is changing (S52: YES), and the change of the normal symbol. It is determined whether time has passed (S81). When the value of the normal symbol fluctuation time counter set in the process of S77 is "0", it is determined that the fluctuation time has elapsed (S81: YES), and the normal symbol stop command is stored in the RAM 52. (S82). This command is transmitted to the relay board 47 by the command output process (S10, see FIG. 11) and normally instructs the stop of fluctuation of the symbol. Then, a predetermined normal symbol stop display time is stored in the normal symbol stop time counter (S83). "2" indicating that the normal symbol is being stopped and displayed is stored in the normal symbol display state flag (S84), and the process returns to the main process. On the other hand, in the determination of S81, when it is determined that the variation time has not yet elapsed (S81: NO), the process returns to the main process.

Further, in the determination of S53, if "2" is stored in the normal symbol display state flag (S53: YES), the normal symbol stop display time has elapsed depending on the value of the normal symbol stop time counter set in S83. It is determined whether or not (S86). If the value of the normal symbol stop time counter is not "0", it is determined that the normal symbol stop display time has not yet elapsed (S86: NO), and the process returns to the main process. When the normal symbol stop display time has elapsed (S86: YES), "0" indicating that the normal symbol is neither changing nor in stop display is stored in the normal symbol display state flag (S87). Next, it is determined whether or not the determination result of the normal hit determination is a normal hit (S88). When the determination result of the normal hit determination is out (S88: NO), the process returns to the main process. When the determination result of the normal hit determination is a normal hit (S88: YES), the normal hit game flag is set to "ON" (S89), and the process returns to the main process.

The details of the normal electric auditors product processing (S15, see FIG. 11) will be described with reference to FIG. The flags used in the normal electric accessory processing will be described. In the normal electric accessory processing, in addition to the various flags described above, a flag for opening the power cable and the like are used. The power-chu open flag is a flag indicating whether the opening/closing member 111 of the power-chu 11 is in the open state, and is stored in the RAM 52. The opening flag of the power tube is set to "ON" by storing "1" while the opening/closing member 111 of the power tube 11 is opened, and "0" is stored when the opening/closing member 111 of the power tube 11 is closed. Is turned off.

When the normal electric auditors product processing is started, it is determined whether or not the normal winning game is being played (S91). This determination is made based on the state of the normal winning game flag. When the normal hit game flag is "OFF" (S91: NO), the process returns to the main process.

When the normal hit game flag is "ON" (S91: YES), it is determined whether the opening/closing member 111 of the electric chew 11 is open (S92). This determination is made based on the state of the power cable open flag. If the power cable open flag is "ON" (S92: YES), the process proceeds to S103.

When the power-chew opening flag is "OFF" (S92: NO), the power-chew opening pattern stored in the RAM 52 is referred to in the process of S75 (see FIG. 13) (S93). Next, it is determined whether or not the referenced electric charge opening pattern is the first pattern P1 (S94). When the referenced electric Chu opening pattern is the first pattern P1 (S94: YES), the P1 opening command is stored in the RAM 52 (S95). The P1 opening command is a command for opening/closing the opening/closing member 111 of the power cable 11 in the first pattern P1 shown in FIG. 7. The P1 release command is transmitted to the relay board 47 in the command output process of the main process to be executed next time (S10, see FIG. 11). Upon receiving the P1 opening command via the relay board 47, the electric Chu solenoid 68 opens/closes the opening/closing member 111 of the electric Chu 11 in the first pattern P1. The process proceeds to S101.

When the power cable release pattern is the second pattern P2 (S94: NO), the P2 release command is stored in the RAM 52 (S98). The P2 opening command is a command for opening/closing the opening/closing member 111 of the power tube 11 in the second pattern P2 shown in FIG. 7. The P2 release command is transmitted to the relay board 47 in the command output process of the main process to be executed next time (S10, see FIG. 11). Upon receiving the P2 opening command via the relay board 47, the electric Chu solenoid 68 opens/closes the opening/closing member 111 of the electric Chu 11 in the second pattern P2. The process proceeds to S101.

Next, the power tube opening flag is turned on (S101), and the distribution shutter operation command is stored in the RAM 52 (S102). The distribution shutter operation command is a command for operating the distribution shutter 195 in the distribution shutter operation pattern shown in FIG. 7. The distribution shutter operation command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The distribution shutter solenoid 69, which has received the distribution shutter operation command via the relay board 47, operates the distribution shutter 195 in the distribution shutter operation pattern. The process proceeds to S103.

Next, it is determined whether or not the game ball has won the electric power chute 11 (S103). When the electric Chu switch 64 detects the winning of the game ball, the flag corresponding to the electric Chu switch 64 becomes "ON" in the switch reading processing of the main processing (S11, see FIG. 15). If the flag corresponding to the electric Chu switch 64 is "ON", it is determined that the game ball has won the electric Chu 11 (S103: YES), and the RAM 52 that counts the number of game balls that have won the electric Chu 11. "1" is added to the electric-chu prize-winning sphere number counter (S105). At this time, an electric-chu prize command for notifying that the game ball has won the electric-chu 11 is stored in the RAM 52. The Den Chu prize command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control board 45, which has received the electric-chu prize command, transmits a signal for paying out one prize ball to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S111. If the flag corresponding to the electric choo switch 64 is "OFF", it is determined that no gaming ball has been won in the electric chew 11. When the game ball has not been won in the electric ball 11 (S103: NO), the process proceeds to the determination of S111.

Next, it is determined whether or not the number of winning balls to the electric Chu 11 is “1” or more (S111). When the value of the Deng Chu winning ball number counter is less than "1" (S111: NO), it is determined whether the opening/closing member 111 of the Deng Chu 11 has finished the opening/closing operation in the first pattern P1 or the second pattern P2. (S112). This judgment is made depending on whether the time from time T0 to time T10 shown in FIG. 7 has elapsed. If the opening/closing operation of the opening/closing member 111 is not completed (S112: NO), the process returns to the main process. In the ordinary electric auditors product processing to be performed thereafter, these judgments are repeatedly executed until one or more game balls are won in the electric Chu 11 or the opening/closing operation of the opening/closing member 111 is completed (S111: NO). , S112: NO).

When one or more game balls are won in the electric chew 11 (S111: YES) or when the opening/closing operation of the opening/closing member 111 is completed (S112: YES), the electric chew closing command is stored in the RAM 52 (S113). .. The power-chu close command is a command for closing the opening/closing member 111 of the open power-chu 11. The power-chu close command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The electric power solenoid 68 that has received the electric power close command from the relay board 47 closes the opening/closing member 111 of the power power supply 11. Next, the power cable open flag is set to "OFF" (S115). In addition, the normal hit game flag is set to "OFF" (S116). The process returns to the main process.

Details of the special symbol processing (S14, see FIG. 11) will be described with reference to FIGS. 15 to 21. First, the flag used in the special symbol processing will be described. In addition to the various flags described above, the RAM 52 stores a big hit game state flag, a small hit medium flag, a special symbol display state flag, and the like.

The jackpot gaming state flag is a flag indicating whether the jackpot game is being played, "1" is stored in the jackpot gaming state and becomes "ON", and "0" is stored when it is not in the jackpot gaming state. "OFF". In addition, that the jackpot gaming state flag is "ON" indicates that the accessory continuous operation device is operating due to the operation of the condition device. The small hitting flag is a flag indicating whether the small hitting game is being performed, "1" is stored during the small hitting game and becomes "ON", and "0" is stored when the small hitting game is not being performed. Will be "OFF". The special symbol display state flag is "1" when one of the first special symbol and the second special symbol is changing (during change), and when one of them is stopped and displayed (during stop display) “2”, and “0” is stored when neither change nor stop display is in progress.

As shown in FIG. 19, when the special symbol process is started, it is determined whether or not a game ball has been won in the first starting opening 12 (S121). When the first starting opening switch 61 detects the winning of the game ball, the flag corresponding to the first starting opening switch 61 becomes "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If this flag is not "ON", it is determined that the game ball has not won (S121: NO), and the process proceeds to the determination of S131. If the game ball has won in the first starting opening 12 (S121: YES), the first starting opening winning command for notifying that the game ball has won in the first starting opening 12 is stored in the RAM 52. .. The first start opening prize command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control board 45, which has received the first start opening prize command, transmits a signal for paying out one prize ball to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S124.

Next, it is determined whether the first number of reserved balls is "1" (S124). If the first number of reserved balls stored in the RAM 52 is "1" (S124: YES), the number of retained balls that can be stored has reached the upper limit, and the process proceeds to the determination of S131. When the first number of reserved balls is not "1" (S124: NO), "1" is added to the first number of reserved balls stored in the RAM 52 (S125). Next, the first random number is acquired and stored in the storage area with the smallest number among the empty storage areas in the first jackpot relationship information storage area (see FIG. 6) (S126). Specifically, the value of the first jackpot determination counter in the first jackpot random number column, the value of the first special symbol determination counter in the first special symbol determination random number column, the first in the first variation pattern determination random number column The value of one fluctuation pattern determination counter is stored in the RAM 52, respectively. After that, the processing shifts to the determination of S131.

Next, it is determined whether or not a game ball has won in the second starting opening 13 (S131). When the second starting opening switch 62 detects the winning of the game ball, the flag corresponding to the second starting opening switch 62 becomes "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If this flag is not "ON", it is determined that no game ball has been won (S131: NO), and the process proceeds to the determination of S141 (see FIG. 16). If the game ball has won in the second starting port 13 (S131: YES), the second starting port winning command for notifying that the game ball has won in the second starting port 13 is stored in the RAM 52. .. The second starting opening winning command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control substrate 45, which has received the second start opening winning command, transmits a signal for paying out one prize ball to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. Then, it is determined whether the second number of reserved balls is "1" (S132). If the second number of reserve balls stored in the RAM 52 is "1" (S132: YES), the number of reserve balls that can be stored has reached the upper limit, and thus the process proceeds to the determination of S141. When the second number of reserved balls is not "1" (S132: NO), "1" is added to the second number of reserved balls stored in the RAM 52 (S133). Next, the second random number is acquired (S135). The acquired second random number is stored in the determination area of the second jackpot-related information storage area (S135).

Next, as shown in FIG. 16, it is determined whether or not it is a jackpot gaming state (S141). When the jackpot gaming state flag is "ON", it is determined that the jackpot gaming state is in progress (S141: YES), and the process returns to the main process. When the jackpot gaming state flag is "OFF", it is determined that the jackpot gaming state is not in progress (S141: NO), and it is determined whether any of the first special symbol and the second special symbol is changing ( S142). If the special symbol display state flag is not "1", it is determined that neither is changing (S142: NO), it is determined whether one of the first special symbol and the second special symbol is in the stopped state (S143). When the special symbol display state flag is not “2”, it is determined that neither is in stop display (S143: NO), the process proceeds to S151 (see FIG. 17), and a jackpot determination process or the like is performed.

In the present embodiment, in the jackpot determination, the second jackpot determination is prioritized over the first jackpot determination. As shown in FIG. 17, first, it is determined whether or not the second number of reserved balls stored in the second jackpot-related information storage area is “1” (S151). When the second number of reserved balls is "1" (S151: YES), the second jackpot determination is performed, which will be described later in detail. When the second number of reserved balls is "0" (S151: NO), it is determined whether the number of first reserved balls stored in the first jackpot relation information storage area is "1" or more ( S152). If the first number of reserved balls is "0" (S152: NO), the process returns to the main process.

When the first number of reserved balls is "1" or more (S152: YES), "1" is subtracted from the first number of reserved balls stored in the first jackpot relationship information storage area (S153). Next, the determination area of the first jackpot related information storage area (see FIG. 6) is shifted to the storage area of the next number (S155). The process proceeds to S163.

On the other hand, in the second jackpot determination, first, the number of second retained balls is decremented by "1" (S161). Next, the determination area of the second jackpot related information storage area is shifted to the storage area of the next number (S162). The process proceeds to S163.

Next, a jackpot determination process is performed (S163). Although not shown, the ROM 53 stores a first jackpot determination table for performing the first jackpot determination and a second jackpot determination table for performing the second jackpot determination. In the first jackpot determination table, random number values of jackpot random numbers respectively corresponding to "big hit", "small hit" and "off edge" are defined. When the first jackpot random number is shifted to the determination area by the process of S155, the first jackpot determination table is referred to, and the first jackpot random number in the determination area is "big hit", "small hit", and "offset". Which of the above is supported is determined. Accordingly, the first jackpot determination based on the undetermined first jackpot random numbers stored in the first jackpot relationship information storage area is performed in the order in which the first jackpot random numbers are stored.

In the second jackpot determination table, random number values of jackpot random numbers respectively corresponding to “big hit” and “off” are defined. When the second jackpot random number is shifted to the determination area by the process of S162, the second jackpot determination table is referred to, and the first jackpot random number in the determination area corresponds to either "big hit" or "outside hit". It is determined whether to do it. As a result, the second jackpot determination based on the undetermined second jackpot random numbers stored in the second jackpot relationship information storage area is performed in the order in which the second jackpot random numbers are stored.

Next, it is determined whether or not the result of the jackpot determination is a jackpot (S171). When the result of the jackpot determination is a jackpot (S171: YES), the special symbol determination table (see FIG. 9) is referred to, and the jackpot type of the first special symbol or the second special symbol is determined (S172). In the process of S172, the jackpot type corresponding to the value of the special symbol determination random number acquired at the same time as the jackpot random number stored in the determination area shifted in S155 and S162 is determined. The determined jackpot type is stored in the RAM 52. The process proceeds to S181.

When the result of the big hit determination is not a big hit (S171: NO), it is determined whether the result of the big hit determination is a small hit (S173). When the result of the big hit determination is a small hit (S173: YES), the special symbol determination table is referred to, and the small hit type of the first special symbol is determined (S174). In the process of S174, the small hit type corresponding to the value of the special symbol determination random number acquired at the same time as the big hit random number stored in the determination area shifted in S155 and S162 is determined. The process proceeds to S181.

If the result of the big hit determination is not a small hit (S173: NO), the predetermined first special symbol or the second special symbol indicating that the determination result of the big hit determination is out (S176), the process proceeds to S181. Transition.

Next, the variation pattern determination process is performed (S181). The variation pattern determination process is a process of determining variation patterns of the first special symbol and the second special symbol. In the variation pattern determination process, the variation pattern determination table is referred to, and whether the jackpot determination is the first jackpot determination or the second jackpot determination, and the determination result of the jackpot determination (jackpot, small hit or out) The table is referred to and the variation pattern of the special symbol is determined.

When the variation pattern is determined, the variation time of the first special symbol or the second special symbol that is determined according to the determined variation pattern is set in the special symbol variation time counter (S183). "1" indicating that one of the first special symbol and the second special symbol is changing is stored in the special symbol display state flag (S184), and the process returns to the main process.

Further, in the determination of S142 shown in FIG. 16, if "1" is stored in the special symbol display state flag, it is determined that one of the first special symbol and the second special symbol is changing ( (S142: YES), it is determined whether the variable time has elapsed (S191). If the value of the special symbol fluctuation time counter set in the process of S183 (see FIG. 17) is “0”, it is determined that the fluctuation time has elapsed (S191: YES), and the special symbol is stopped in the RAM 52. The command is stored (S192). This command is transmitted to the relay board 47 by the command output process (S10, see FIG. 11) and instructs the stop of variation of the first special symbol or the second special symbol. Then, a predetermined special symbol stop display time is stored in the special symbol stop time counter (S193). "2" indicating that either the first special symbol or the second special symbol is being stopped and displayed is stored in the special symbol display state flag (S194), and the process returns to the main process. On the other hand, in the determination of S191, when it is determined that the variation time has not yet elapsed (S191: NO), the process returns to the main process.

Further, in the determination of S143, if "2" is stored in the special symbol display state flag (S143: YES), the special symbol stop display time has elapsed depending on the value of the special symbol stop time counter set in S193. It is determined whether or not (S196). If the value of the special symbol stop time counter is not "0", it is determined that the special symbol stop display time has not yet elapsed (S196: NO), and the process returns to the main process. When the special symbol stop display time has elapsed (S196: YES), "0" indicating that neither the first special symbol nor the second special symbol is changing or in stop display is the special symbol display state flag. It is stored (S197).

Next, it is determined whether the determination result of the jackpot determination executed in S163 is a jackpot (S198). If the determination result is not a big hit (S198: NO), the process returns to the main process. When the determination result is a big hit (S198: YES), the number of rounds corresponding to the big hit type is stored in the RAM 52 as Rmax (S199). In the present embodiment, the jackpot types are all “16R”, so “16” is set as Rmax. The process returns to the main process.

The details of the special electric auditors product process (S13, see FIG. 11) will be described with reference to FIGS. 18 to 20. First, the flag used in the special electric auditors product processing will be described. In the special electric auditors product processing, in addition to the various flags described above, an opening flag and a processing standby flag are used. The open flag is a flag indicating whether or not the first special winning opening 16 and the second special winning opening 17 are open, and is stored in the RAM 52. The open flag is "1" when the opening/closing member 161 of the first special winning opening 16 is open, and "2" when the opening/closing member 161 of the second special winning opening 17 is open. If neither 161 or 171 is opened, "0" is stored. Whether the processing standby flag is in the processing standby state before a predetermined processing time elapses after the entrance of the first special winning opening 16 or the second special winning opening 17 is closed until the next processing is performed. It is a flag indicating whether or not. The processing standby flag is set to "ON" by storing "1" during the processing standby, and turned "OFF" after the processing time elapses. The processing time is set in consideration of the time required for the game balls that have won the first big winning opening 16 or the second big winning opening 17 to be discharged to the outside of the game area 4.

When the special electric auditors product processing is started, it is determined whether or not it is a jackpot gaming state (S201). This determination is made based on the state of the jackpot gaming state flag. When the jackpot gaming state flag is "ON" (S201: YES), it is determined whether or not the process is waiting (S202). This determination is made based on the state of the processing standby flag. When the processing standby flag is “OFF” (S202: NO), the jackpot type determined in S172 (see FIG. 17) and stored in the RAM 52 is referred to, and the determined jackpot type is “16R jackpot A”. It is determined whether there is any (S203).

When the jackpot type is "16R jackpot A" (S203: YES), it is determined whether the opening/closing member 161 of the first winning hole 16 is open (S204). This determination is made depending on whether "1" is stored in the opening flag. When "1" is stored in the opening flag (S204: YES), the process proceeds to the determination of S211.

When "1" is not stored in the opening flag (S204: NO), the first opening command for opening the opening/closing member 161 of the first special winning opening 16 is stored in the RAM 52 (S205). The first release command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The first special winning opening solenoid 70 that has received the opening command via the relay board 47 opens the opening/closing member 161 of the first special winning opening 16.

Next, the first opening time is stored in the first opening time counter (S206). The first time counter is a counter for measuring the first opening time and is stored in the RAM 52. Next, "1" is stored in the opening flag (S208). The process shifts to the determination of S211.

Next, it is determined whether the game ball has won the first big winning opening 16 (S211). When the first big winning opening switch 76 detects the winning of the game ball, the flag corresponding to the first big winning opening switch 76 is turned "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If the flag corresponding to the first big winning opening switch 76 is "ON", it is determined that the game ball has won the first big winning opening 16 (S211: YES), and the first big winning opening 16 is won. "1" is added to the first winning ball number counter of the RAM 52 which counts the number of game balls played (S212). At this time, the first special winning opening winning command for notifying that the game ball has won the first special winning opening 16 is stored in the RAM 52. The first special winning opening winning command is transmitted to the payout control board 45 in the command output processing (S10, see FIG. 11) of the main processing to be executed next time. The CPU 45a of the payout control board 45, which has received the first big winning opening prize command, transmits a signal for paying out three prize balls to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The processing shifts to the determination of S213. If the flag corresponding to the first big winning opening switch 76 is "OFF", it is determined that the game ball has not entered the first big winning opening 16. When the game ball has not won the first big winning opening 16 (S211: NO), the process proceeds to the determination of S213.

Next, it is determined whether or not the number of winning balls into the first special winning opening 16 is “3” or more (S213). When the value of the first winning ball number counter is less than "3" (S213: NO), it is determined whether the first opening time has elapsed based on the value of the first opening time counter (S214). If the first opening time has not elapsed (S214: NO), the process returns to the main process. In the special electric auditors product processing to be performed thereafter, these judgments are repeatedly executed until three or more game balls are won in the first special winning opening 16 or the first opening time has elapsed (S213: NO, S214: NO).

When three or more game balls are won in the first big winning opening 16 (S213: YES) or when the first opening time has elapsed (S214: YES), the first closing command is stored in the RAM 52 (S215). ). The first closing command is a command for closing the opening/closing member 161 of the opened first big winning opening 16. The first closing command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The first special winning opening solenoid 70 that has received the first closing command via the relay board 47 closes the opening/closing member 161 of the first special winning opening 16.

Next, the predetermined processing time is stored in the processing time counter (S216). The processing standby flag is turned “ON” (S218). Further, "0" is stored in the opening flag (S219). The process returns to the main process.

On the other hand, when the jackpot type is "16R jackpot B" (S203: NO), it is determined whether the opening/closing member 171 of the second winning hole 17 is open (S224). This determination is made depending on whether "2" is stored in the opening flag. When "2" is stored in the opening flag (S224: YES), the process proceeds to the determination of S231.

When "2" is not stored in the opening flag (S224: NO), the second opening command for opening the opening/closing member 171 of the second special winning opening 17 is stored in the RAM 52 (S225). The second opening command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The second special winning opening solenoid 71 having received the opening command via the relay board 47 opens the opening/closing member 171 of the second special winning opening 17.

Next, the second opening time is stored in the second opening time counter (S226). The second time counter is a counter for measuring the second opening time and is stored in the RAM 52. Next, "2" is stored in the opening flag (S228). The processing shifts to the determination of S231.

Next, it is determined whether the game ball has won the second big winning opening 17 (S231). When the second special winning opening switch 77 detects the winning of the game ball, the flag corresponding to the second special winning opening switch 77 is turned "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If the flag corresponding to the second big winning opening switch 77 is "ON", it is determined that the game ball has won the second big winning opening 17 (S231: YES), and the second big winning opening 17 is won. "1" is added to the second winning ball number counter of the RAM 52 which counts the number of game balls played (S232). At this time, a second special winning opening winning command for notifying that the game ball has won the second special winning opening 17 is stored in the RAM 52. The second special winning opening winning command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control board 45, which has received the second big winning opening winning command, sends a signal for paying out 15 prize balls to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S233. If the flag corresponding to the second special winning opening switch 77 is "OFF", it is determined that the game ball has not entered the second special winning opening 17. When the game ball has not won the second big winning opening 17 (S231: NO), the process proceeds to the determination of S233.

Next, it is determined whether the number of winning balls to the second big winning opening 17 is “10” or more (S233). When the value of the second winning ball counter is less than "10" (S233: NO), it is determined whether the second opening time has elapsed based on the value of the second opening time counter (S234). If the second opening time has not elapsed (S234: NO), the process returns to the main process. In the special electric auditors product processing performed thereafter, these determinations are repeatedly executed until 10 or more game balls are won in the second special winning opening 17 or the second opening time has elapsed (S233: NO, S234: NO).

When 10 or more game balls are won in the second big winning opening 17 (S233: YES) or when the second opening time has elapsed (S234: YES), the second closing command is stored in the RAM 52 (S235). ). The second closing command is a command for closing the opening/closing member 171 of the opened second big winning opening 17. The second closing command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The second special winning opening solenoid 71 that has received the second closing command via the relay board 47 closes the opening/closing member 171 of the second special winning opening 17. The process proceeds to S216. After that, the processes of S216, S218, and S219 described above are sequentially executed, and the process returns to the main process.

On the other hand, when the big hit game state flag is "OFF" (S201: NO), as shown in FIG. 19, it is determined whether the small hit game is in progress (S241). This determination is made according to the state of the small hitting flag. When the small hitting flag is "OFF" (S241: NO), the process returns to the main process.

When the small hitting medium flag is "ON" (S241: YES), it is determined whether or not the first special winning opening 16 is in the open state (S243). When "1" is stored in the opening flag (S243: YES), the process proceeds to the determination of S251.

When "1" is not stored in the opening flag (S243: NO), the first opening command is stored in the RAM 52 (S245). The first release command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The first special winning opening solenoid 70 that has received the opening command via the relay board 47 opens the opening/closing member 161 of the first special winning opening 16.

Next, the third opening time is stored in the third opening time counter (S246). The third opening time counter is a counter for measuring the third opening time and is stored in the RAM 52. Next, "1" is stored in the opening flag (S248). The processing shifts to the determination of S251.

Next, it is determined whether the game ball has won the first big winning opening 16 (S251). When the first big winning opening switch 76 detects the winning of the game ball, the flag corresponding to the first big winning opening switch 76 is turned "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If the flag corresponding to the first big winning opening switch 76 is "ON", it is determined that a game ball has been won in the first big winning opening 16 (S251: YES), and the first winning ball number counter shows " 1” is added (S252). At this time, the first special winning opening winning command is stored in the RAM 52. The first special winning opening winning command is transmitted to the payout control board 45 in the command output processing (S10, see FIG. 11) of the main processing to be executed next time. The CPU 45a of the payout control board 45, which has received the first big winning opening prize command, transmits a signal for paying out three prize balls to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S253. If the flag corresponding to the first big winning opening switch 76 is "OFF", it is determined that the game ball has not entered the first big winning opening 16. When the game ball has not won the first big winning opening 16 (S251: NO), the process proceeds to the determination of S253.

Next, it is determined whether or not the number of winning balls into the first special winning opening 16 is “3” or more (S253). When the value of the first winning ball number counter is less than "3" (S253: NO), it is determined whether the third opening time has elapsed based on the value of the third opening time counter (S255). If the third opening time has not elapsed (S255: NO), the process returns to the main process. In the special electric auditors product processing to be performed thereafter, these determinations are repeatedly executed until three or more game balls are won in the first special winning opening 16 or the third opening time has elapsed (S253: NO, S255: NO).

When three or more game balls are won in the first big winning opening 16 (S253: YES) or when the third opening time has elapsed (S255: YES), the first closing command is stored in the RAM 52 (S256). ). The first closing command is transmitted to the relay board 47 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The first special winning opening solenoid 70 that has received the first closing command via the relay board 47 closes the opening/closing member 161 of the first special winning opening 16. Next, "0" is stored in the opening flag (S258). The small hitting flag is set to "OFF" (S259), and the process returns to the main process.

When the processing standby flag is “ON” as shown in FIG. 18 (S202: YES), it is determined whether the processing time has elapsed based on the value of the processing time counter as shown in FIG. (S261). If the value of the processing time counter is not "0", it is determined that the processing time has not elapsed (S261: NO), and the processing returns to the main processing. If the value of the processing time counter is "0", it is determined that the processing time has elapsed (S261: YES), and the processing standby flag is turned "OFF" (S262). Next, "1" is added to the value of the R counter (S263).

Next, it is determined whether the value of the R counter and the value of Rmax are equal (S265). If the value of the R counter has not reached Rmax yet and the value of the R counter and the value of Rmax are not equal (S265: NO), the process returns to the main process. When the value of the R counter and the value of Rmax are equal (S265: YES), the value of the R counter and the value of Rmax are cleared to "0" (S266). Next, the jackpot gaming state flag is set to "OFF" (S268). The process returns to the main process.

As explained above, in the pachinko machine 1, the game ball passes the normal symbol operation gate 10 (S43: YES), and the normal hit determination is executed (S65). When it is determined by the normal hit determination that it is a normal hit, the normal hit type is determined at a rate of 85% for "normal hit 1" and 15% for "normal hit 2". When the normal hit type of "normal hit 1" is determined, the opening and closing operation of the electric hit 11 related to the normal hit game is performed in the first pattern P1 (S95). When the ordinary hit type of “ordinary hit 2” is determined, the opening/closing operation of the electric hit 11 related to the ordinary hit game is performed in the second pattern P2 (S98). In the first pattern P1, the game ball that has won the electric power chute 11 passes through the first passing area 192 more easily than the second passing area 193. In the second pattern P2, the gaming balls that have won the electric chow 11 are more likely to pass through the second passage area 193 than the first passage area 192. Therefore, in the normal hit game, the percentage of the game balls won in the electric Chu 11 passing through the first passage area 192 is about 85%, and in the normal hit game, the game balls winning in the electric Chu 11 passes through the second passage area 193. The ratio of doing is about 15%. When the game ball passes through the first passage area 192, the first actuation mechanism operates and the opening/closing member 121 of the first starting opening 12 is opened. When the game ball passes through the second passage area 193, the second actuation mechanism operates and the opening/closing member 131 of the second starting opening 13 is opened. The first jackpot determination is executed when the game ball wins the first starting opening 12. The second jackpot determination is executed when the game ball wins the second starting opening 13. When the first big hit determination is executed, a big hit, small hit, or out-of-judgment determination result is obtained. When the second jackpot determination is executed, the determination result of either the jackpot or the outfall is obtained. Therefore, when the game ball wins the electric ball 11 in the normal hit game, the jackpot game or the small hit game based on the determination result of the first jackpot determination is more easily executed than the jackpot game based on the determination result of the second jackpot determination. ..

On the other hand, in the pachinko machine 1, the expected value of the total number of prize balls paid out according to the determination result of the second jackpot determination is greater than the expected value of the total number of prize balls paid out according to the determination result of the first jackpot determination. Is also big. Therefore, the player playing the pachinko machine 1 normally proceeds with the game while obtaining the prize balls paid out according to the determination result of the first jackpot determination, and the jackpot game according to the determination result of the second jackpot determination is When it occurs, the player can experience a change in the feeling of playing a ball. Such a pachinko machine 1 can normally advance the game to the player by continuing to shoot the game ball toward the normal symbol operation gate 10. Further, when the accessory such as the electric Chu 11, the first starting opening 12, the second starting opening 13, the first big winning opening 16 and the second big winning opening 17 is opened, the player aims at the opened opening. The game procedure is clear because it only has to shoot the game balls. Therefore, the pachinko machine 1 can provide a game playability that is easy to understand and is easy to play, and that changes can sometimes occur.

In the pachinko machine 1, when the game ball passes through the first passage area 192, the opening/closing member 121 of the first starting opening 12 is opened, and when the game ball passes through the second passage area 193, the opening/closing member of the second starting opening 13 is opened. 131 is opened. The first jackpot determination is executed when the game ball wins the first starting opening 12. The second jackpot determination is executed when the game ball wins the second starting opening 13. In the pachinko machine 1, in the ordinary symbol determination table, the value of the ordinary symbol determination random number is assigned to each ordinary hit type so that “ordinary 1” is 85% and “ordinary 2” is 15%. ing. The "normal hit 1" is associated with the first pattern P1, and the "normal hit 2" is associated with the second pattern P2. For example, by changing the value of the normal symbol determination random number in the normal symbol determination table, it is possible to easily adjust the execution frequency of the first jackpot determination and the second jackpot determination. In the pachinko machine 1, the probability of obtaining a jackpot or small hit determination result that is a determination result other than deviance in the first jackpot determination is a large jackpot determination result that is a determination result other than defeat in the second jackpot determination. It is designed to be higher than the probability of being hit. Therefore, the pachinko machine 1 pays out the prize ball by the small hit game or the big hit game executed as the judgment result of the first big hit judgment even in the situation where the big hit game according to the judgment result of the second big hit judgment is difficult to be executed. Thus, the player can easily continue the game.

In the pachinko machine 1, the first jackpot determination is performed when the game ball wins the first starting opening 12. The first small hit probability in the first big hit determination is higher than the big hit probability. Therefore, when the first big hit determination is performed, the small hit is determined with a higher probability than the big hit is determined. Therefore, when the game ball wins the first starting opening 12, the small hit game of "small hit A" is executed with a probability higher than that of the big hit game of "16R big hit A". .. That is, as a result of the determination by the first big hit determination, the small hit game is executed more frequently than the big hit game. Therefore, even if the player finds it difficult to obtain a prize ball for a big hit game, the player can easily continue the game while obtaining a prize ball for a small hit game as a base.

As shown in FIG. 21, the game board 2 of the pachinko machine 100 is provided with a third special winning opening 27 diagonally below and to the right of the electric chew 11. The third big winning opening 27 is configured as a winning opening for a special electric accessory. The third special winning opening 27 includes an opening/closing member 271 that is electrically opened/closed by a third special winning opening solenoid 72 (see FIG. 22). The opening/closing member 271 is a substantially flat plate-shaped member extending in the front-rear direction. The opening/closing member 271 covers the entrance of the third big winning opening 27 from the upper part in the closed state to prevent the winning of the game ball into the third big winning opening 27, and slides backward in the open state to cause the third big opening. The entrance of the winning opening 27 is opened, and the game ball can be entered into the third big winning opening 27. Only when the opening/closing member 271 is opened, the game ball can win the third big winning opening 27.

Inside the third big winning opening 27, a specific area 272, a non-specific area 273, and a movable piece 274 are provided. The specific area 272 and the non-specific area 273 are areas through which only the game balls that have won the third big winning opening 27 can pass. The movable piece 274 is a substantially flat plate-shaped member extending in the front-rear direction, and is electrically operated by the movable piece solenoid 73 (see FIG. 22). The movable piece 274 prevents the game ball from passing through the specific area 272 by covering the specific area 272 from the upper side in the closed state, and opens the upper side of the specific area 272 by sliding backward in the open state, thereby playing the game. The sphere is allowed to pass through the specific area 272. In the present embodiment, the movable piece 274 is arranged so that the ratio of the game balls that pass through the specific area 272 among the game balls that have won the third big winning opening 27 becomes a predetermined ratio (for example, about 1/10). It is operated in a predetermined operation pattern. The ratio of the game balls that have passed through the specific area 272 to all the game balls that have won the third big winning opening 27 is hereinafter referred to as "V rate". The game ball that has won the third big winning opening 27 passes through either the specific area 272 or the non-specific area 273 and is then discharged to the outside of the game area 4.

The playability of the pachinko machine 100 will be described. In the pachinko machine 100, it is determined by the first big hit determination whether the big hit, the small hit, or the out-of-hit is based on the first big hit random number. Further, by the second big hit judgment, it is judged whether the small hit or the big hit is based on the second big hit random number. Although the pachinko machine 100 is set so as not to be determined to be a big hit by the second big hit determination, the pachinko machine 100 is also determined to be a big hit, a small hit or a deviant by the second big hit determination. It may be set to be performed. In the present embodiment, the third big winning opening 27 is configured to switch between an open state and a closed state as a small hit game when the result of the second big hit determination is a small hit.

In the pachinko machine 100, if it is determined to be a small hit by the second big hit determination, the second special symbol indicating that the determination result is a small hit is confirmed and displayed on the second special symbol display portion of the symbol display portion 24. It After the special symbol indicating the small hit is confirmed and displayed on the symbol display unit 24, the small hit game in which the opening/closing member 271 of the third special winning opening 27 is opened for a predetermined time in a predetermined opening pattern is executed. In this embodiment, the opening/closing member 271 of the third big winning opening 27 is opened once for a predetermined time in the small hit game. At the time when the determination result of the big hit determination is the small hit, the condition device does not operate. Therefore, when the determination result of the second jackpot determination is a small hit, the accessory continuous operation device does not operate.

In the small hit game, when the game ball that has won the third big winning opening 27 in which the opening/closing member 271 is opened passes the specific area 272, the condition device operates. With the operation of the condition device, when the accessory continuous operation device operates, a big hit game state occurs, and a big hit game is executed following the small hit game. That is, the specific area 272 corresponds to a “specific area” for operating the condition device. In this way, the small hit game is executed due to the fact that it is determined to be the small hit in the second big hit judgment, and when the big hit game is executed by passing the game ball through the specific area 272, The small hit game executed in the above is included in a part of the big hit game. In this case, the small hit game is dealt with as a big hit round of the 1R, and is converted into the number of rounds as the 1R big hit round. In this modified example, in the jackpot game executed when the game ball that has won the third big winning opening 27 passes through the specific area 272, the third big winning opening 27 opens a maximum of 28.0 seconds 1 Do it once.

In this way, in the pachinko machine 100, the jackpot game corresponding to the “16R jackpot A” can be executed when the game ball wins the first starting opening 12. In the pachinko machine 100, the game ball passes through the specific area 272 inside the third big winning opening 27 during the small hitting game that can be executed when the game ball wins the second starting opening 13. Under the condition, the big hit game is executed subsequently to the small hit game. In the pachinko machine 100, a big hit game using the first big winning opening 16 without a specific area and a big hitting game similar to a so-called winged type gaming machine using a third big winning opening 27 having a specific area 272. And both can be performed. Therefore, the pachinko machine 100 can provide a player with a jackpot game that changes. The feather-type game machine is widely popular as a game machine that can be played easily. Therefore, the pachinko machine 100 is easily recognized as a game machine that can be played easily.

In the pachinko machine 100, the probability of being a small hit in the second big hit judgment (hereinafter, referred to as “second small hit probability”) is, for example, 10/50. In the pachinko machine 100, the second small hit probability is set to be lower than the probability (41/50) of obtaining a large hit or small hit determination result that is a determination result other than the outlier in the first large hit determination. That is, the second jackpot probability in the second jackpot determination is lower than the combined probability of the jackpot probability and the first jackpot probability in the first jackpot determination. Therefore, the pachinko machine 100, like the pachinko machine 1, normally advances the game to the player while obtaining the prize balls to be paid out according to the determination result of the first jackpot determination. Then, when the big hit game according to the determination result by the second big hit determination occurs, the pachinko machine 1 can allow the player to experience a change in the payout feeling.

Here, the expected value of the prize balls paid out according to the jackpot game executed as the determination result of the second jackpot determination in the pachinko machine 100 is executed as the determination result of the second jackpot determination in the pachinko machine 1 of the above embodiment. It is about the same as the expected value of the prize balls paid out according to the jackpot game. When the pachinko machine 1 and the pachinko machine 100 are determined to have the same degree of payout performance in the special prize, the second small hit probability of the pachinko machine 100 is higher than the jackpot probability of the pachinko machine 1 in the above embodiment by V. It can be higher depending on the rate. In this case, in the pachinko machine 100, the probability that a determination result other than the deviation is generated by the second big hit determination can be higher than that in the pachinko machine 1. Therefore, the pachinko machine 100 is more likely than the pachinko machine 1 to cause a change in game triggered by the game ball winning the second starting opening 13. In this way, depending on whether the structure of the special winning opening to be opened according to the judgment result of the second big winning judgment is the second special winning opening 17 or the third big winning opening 27. The designer can change the degree of occurrence of the game that leads to the prize according to the execution of the second jackpot determination.

The electrical characteristics of the pachinko machine 100 will be described with reference to FIG. The controller 400 of the pachinko machine 100 mainly includes a main board 41, a sub control board 58, a lamp driver board 46, a payout control board 45, a relay board 470, and a power supply board 42. Relay board 470, in addition to the electric Chu switch 64, electric Chu solenoid 68, distribution shutter solenoid 69, the first big winning opening solenoid 70, the gate switch 75, the first big winning opening switch 76 and the symbol display unit 24, It is connected to the three major winning opening solenoid 72, the movable piece solenoid 73, the third major winning opening switch 78, and the specific area switch 79. The third big winning opening solenoid 72 opens and closes the opening/closing member 271 of the third big winning opening 27 during the small hitting game and the big hitting game. The movable piece solenoid 73 opens and closes the movable piece 274 of the third big winning opening 27 during the small hit game. The third big winning opening switch 78 is provided in the third big winning opening 27, and detects a game ball that has won the third big winning opening 27. The specific area switch 79 is provided in the specific area 272 of the third special winning opening 27, and detects a game ball that has passed through the specific area 272. The other electrical characteristics of the pachinko machine 100 are the same as those of the pachinko machine 1.

The special symbol determination table stored in the ROM 53 of the pachinko machine 100 will be described with reference to FIG. The pachinko machine 100, the first special symbol indicating that the result of the first jackpot determination is a big hit or a small hit, and the second special symbol indicating that the result of the second jackpot determination is a small hit, the special symbol determination Determined by referring to the table. The hit type of the first special symbol includes a jackpot type indicating that the result of the jackpot determination is a jackpot, and a jackpot type indicating that the result of the jackpot determination is a jackpot. The hit type of the second special symbol includes a small hit type indicating that the result of the big hit determination is a small hit.

In the special symbol determination table, a value (0 to 99) of the special symbol determination random number is associated with each of the plurality of winning types. As shown in FIG. 23, in the pachinko machine 100, when the jackpot machine 1 determines that the jackpot is a big hit, the jackpot type “16R jackpot A” is determined at a rate of 100%, as in the case of the pachinko machine 1. .. If the first big hit determination determines that the small hit is a small hit, the small hit type of “small hit A” is determined at a rate of 100%.

When the second big hit determination determines that the small hit is a small hit, the small hit type “small hit B” is determined at a rate of 100%. Note that the second special symbol is not limited to this, and may include a plurality of types of small hit types and large hit types. When the small hit type of “small hit B” is determined, the game ball winning the third big winning opening 27 passes through the specific area 272 while the small hit game corresponding to “small hit B” is being executed. The jackpot gaming state is generated. In this case, the 16R big hit game is executed subsequently to the small hit game. If the small hit game corresponding to "small hit B" is executed, but the game ball does not pass through the specific area 272, and the big hit game state is not generated, the big hit game is finished after the small hit game. Is not executed.

The special symbol determination table defines the opening pattern of the first big winning opening 16 and the third big winning opening 27 in each jackpot round. In the small hit game executed based on the hit type of "small hit B", the third big winning opening 27 is opened once for a maximum of 1.5 seconds. As described above, in the jackpot game resulting from the execution of the jackpot game, the jackpot game is dealt with retrospectively as the jackpot round of the 1R. Therefore, in the special symbol determination table, the opening time of the third big winning opening 27 relating to the small hit game is defined as the opening time of the first R big hit round for convenience. Hereinafter, the maximum opening time of the third big winning opening 27 in the small hit game executed based on the hit type of "small hit B" is also referred to as a fourth opening time below. In the big hit game resulting from the fact that the small hit game corresponding to “small hit B” is executed, the third big winning opening 27 opens once for a maximum of 28.0 seconds once in each round from 2R to 16R. In addition, the maximum opening time of the third big winning opening 27 in one big hit round of the big hit game is set to the second opening time, like the pachinko machine 1.

In this modified example, if 10 or more game balls are won in the third big winning opening 27, the third big winning opening 27 will be opened even if the fourth opening time or the second opening time has not elapsed. finish. The number of winning prizes at which the third major winning opening 27 finishes opening even if the fourth opening time or the second opening time has not elapsed is hereinafter also referred to as a third winning possible number.

In order to realize the above game specifications, in the CPU 51 of the pachinko machine 100 according to the modified example, in the special electric auditors product processing in the above embodiment, the processing shown in FIGS. 18 and 19 is replaced with the processing shown in FIGS. The indicated process is executed. Note that among the processes shown in FIGS. 24 and 25, the processes having the same step numbers as the processes shown in FIGS. 18 and 19 are the same as the processes shown in FIGS. 18 and 19, and thus the description thereof will be omitted.

As shown in FIG. 24, the operation of the first special winning opening 16 in the jackpot game is controlled by the processing of S201 to S219. In the process of S203, if the jackpot type is not "16R jackpot A" (S203: NO), the jackpot game resulting from the jackpot game corresponding to "jackpot B" being executed is being executed. Therefore, the operation of the third big winning opening 27 in the jackpot game is controlled. Therefore, it is determined whether the opening/closing member 271 of the third big winning opening 27 is open (S221). The open flag stored in the RAM 52 in the modified example indicates whether or not the first special winning opening 16 and the third special winning opening 27 are in the open state. When it is determined that the third special winning opening 27 is open based on the state of the opening flag (S221: YES), the process proceeds to the determination of S230.

When it is determined that the third special winning opening 27 is not opened based on the state of the opening flag (S221: NO), a third opening command for opening the opening/closing member 271 of the third special winning opening 27. Is stored in the RAM 52 (S222). The third release command is transmitted to the relay board 470 in the command output process (S10, see FIG. 11) of the main process to be executed next time. Upon receiving the opening command via the relay board 470, the third special winning opening solenoid 72 opens the opening/closing member 271 of the third special winning opening 27. Next, the second opening time is stored in the second opening time counter (S226). Further, "2" indicating that the third special winning opening 27 is in the open state is stored in the open flag (S228). The process shifts to the determination of S230.

Next, it is determined whether the game ball has won the third big winning opening 27 (S230). When the third special winning opening switch 78 detects the winning of the game ball, the flag corresponding to the second special winning opening switch 77 is turned "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If the flag corresponding to the third big winning opening switch 78 is "ON", it is determined that the game ball has won the third big winning opening 27 (S230: YES), and the third big winning opening 27 is won. "1" is added to the third winning ball number counter of the RAM 52 which counts the number of game balls played (S237). At this time, the third big winning opening winning command for notifying that the game ball has won the third big winning opening 27 is stored in the RAM 52. The third special winning opening winning command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control board 45, which has received the third big winning opening prize command, transmits a signal for paying out 15 prize balls to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S233. If the flag corresponding to the third big winning opening switch 78 is "OFF", it is determined that the game ball has not entered the third big winning opening 27. When the game ball has not won the third big winning opening 27 (S230: NO), the process proceeds to the determination of S233.

Next, it is determined whether the number of winning balls into the third big winning opening 27 is “10” or more (S233). When the value of the third winning ball number counter is less than "10" (S233: NO), it is determined whether the second opening time has elapsed based on the value of the second opening time counter (S234). If the second opening time has not elapsed (S234: NO), the process returns to the main process. In the special electric auditors product processing performed thereafter, these determinations are repeatedly executed until 10 or more game balls are won in the third big winning opening 27 or the second opening time has elapsed (S233: NO, S234: NO).

When 10 or more game balls are won in the third big winning opening 27 (S233: YES) or when the second opening time has elapsed (S234: YES), the third closing command is stored in the RAM 52 (S239). ). The third closing command is a command for closing the opening/closing member 271 of the opened third big winning opening 27. The third closing command is transmitted to the relay board 470 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The second special winning opening solenoid 71 that has received the second closing command via the relay board 470 closes the opening/closing member 171 of the second special winning opening 17. The process proceeds to S216. After that, the processes of S216, S218, and S219 described above are sequentially executed, and the process returns to the main process.

On the other hand, when the big hit game state flag is "OFF" (S201: NO), as shown in FIG. 25, it is determined whether or not the small hit game is being played (S241). When the small hit game is not being played (S241: NO), the process returns to the main process.

When the small hit game is being played (S241: YES), it is determined whether the determined small hit type is "small hit A" (S242). When the small hit type is "small hit A" (S242: YES), the process of S243 to S263 controls the operation of the first special winning opening 16 in the small hit game corresponding to "small hit A". The details of the processing from S261 to S263 will be described later.

When the small hit type is "small hit B" (S242: NO), it is determined whether the third special winning opening 27 is open (S271). When the third big winning opening 27 is in the open state (S271: YES), the process proceeds to S281.

When the third big winning opening 27 is not open (S271: NO), the third opening command is stored in the RAM 52 (S272). The third release command is transmitted to the relay board 470 in the command output process (S10, see FIG. 11) of the main process to be executed next time. Upon receiving the opening command via the relay board 47, the third special winning opening solenoid 72 opens the opening/closing member 271 of the third special winning opening 27.

Next, the fourth opening time is stored in the fourth opening time counter (S273). The fourth opening time counter is a counter for measuring the fourth opening time and is stored in the RAM 52. Next, "2" is stored in the opening flag (S275).

Next, the movable piece operating command for operating the movable piece 274 in the third big winning opening 27 is stored in the RAM 52 (S276). The movable piece operation command is transmitted to the relay board 470 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The movable piece solenoid 73 which has received the movable piece operation command via the relay board 470 operates the movable piece 274 in a predetermined operation pattern during the small hitting game. The processing shifts to the determination of S281.

Next, it is determined whether the game ball has won the third big winning opening 27 (S281). When the game ball has won the third big winning opening 27 (S281: YES), "1" is added to the third prize ball number counter (S282). At this time, the third big winning opening winning command is stored in the RAM 52. The third special winning opening winning command is transmitted to the payout control board 45 in the command output process (S10, see FIG. 11) of the main process to be executed next time. The CPU 45a of the payout control board 45, which has received the third big winning opening prize command, transmits a signal for paying out 15 prize balls to the prize ball payout device 49. The prize ball payout device 49 pays out prize balls in response to the reception of the signal. The process shifts to the determination of S283. When the game ball has not won the third big winning opening 27 (S281: NO), the processing shifts to the determination of S283.

Next, it is determined whether the number of winning balls into the third big winning opening 27 is “10” or more (S283). When the value of the third winning ball number counter is less than "10" (S283: NO), it is determined whether the fourth opening time has elapsed based on the value of the fourth opening time counter (S285). If the fourth opening time has not elapsed (S285: NO), the process returns to the main process. In the special electric auditors product processing performed thereafter, these determinations are repeatedly executed until 10 or more game balls are won in the third big winning opening 27 or the fourth opening time has elapsed (S283: NO, S285: NO).

When 10 or more game balls are won in the third big winning opening 27 (S283: YES) or when the fourth opening time has elapsed (S285: YES), the third closing command is stored in the RAM 52 (S239). ). Next, "0" is stored in the opening flag (S258). In addition, the small hitting flag is turned off (S259).

Next, it is determined whether or not the game ball has passed the specific area 272 in the small hit game (S261). When the specific area switch 79 detects the passage of the game ball, the flag corresponding to the specific area switch 79 is turned "ON" in the switch reading processing of the main processing (S11, see FIG. 11). If the flag corresponding to the specific area switch 79 is "OFF", it is determined that the game ball has not passed through the specific area 272 (S261: NO), and the processing returns to the main processing.

If the flag corresponding to the specific area switch 79 is "ON", it is determined that the game ball has passed through the specific area 272 (S261: YES), and the jackpot gaming state flag is "ON" (S262). ). That is, in the small hit game corresponding to the "small hit B", the condition device operates and the accessory continuous operation device operates because the game ball passes through the specific area 272. Next, "1" is added to the value of the R counter (S263). The R counter is a counter that counts the number of rounds executed in the jackpot game and is stored in the RAM 52. That is, with the operation of the accessory continuous operation device, the small hit game is treated as a big hit round of the 1R and converted into the number of rounds as the big hit round of 1R. After that, the process returns to the main process.

As described above, in the pachinko machine 100, the specific area 272 is provided inside the third special winning opening 27. When it is determined that the game is a small hit by the second big hit determination executed when the game ball wins the second starting opening 13, the small hit type of "small hit B" is determined. When the small hit game corresponding to "small hit B" is executed, the movable piece 274 is operated in a predetermined operation pattern. Therefore, when the game ball wins the third big winning opening 27 in the small hit game, the won game balls pass through the specific area 272 at a predetermined ratio. When the game ball passes through the specific area 272 (S261: YES), the big hit game is executed subsequently to the small hit game (S262, S221 to S239). In this way, the pachinko machine 100, in addition to the jackpot game using the first special winning opening 16 that does not include a specific area, a jackpot game similar to a feather type gaming machine using the third special winning opening 27. I can do it. The pachinko machine 100 allows the player to easily enjoy the game according to the playability of the feather type. The third big winning opening 27 of the modified example corresponds to the "second big winning opening" of the present invention. The specific area 272 corresponds to the “specific area” of the present invention.

The present invention is not limited to the embodiments and modifications described above in detail, and various modifications can be made without departing from the gist of the present invention. In the above embodiment, the normal hit determination is executed when the game ball passes through the normal symbol actuation gate 10, and the normal hit game is executed according to the result of the normal hit determination. For example, when the game ball passes through the normal symbol operation gate 10, the normal hit game may be executed without the normal hit determination being performed. In this case, one of the first pattern P1 and the second pattern P2 may be determined as a predetermined electric charge opening pattern when the game ball passes through the normal symbol operation gate 10. Further, the normal symbol operation gate 10 is configured as a winning opening, and the winning ball may be paid out to the game ball winning the winning opening.

In the above embodiment, the first jackpot determination is executed when the game ball wins the first starting opening 12, and the second jackpot determination is executed when the game ball wins the second starting opening 13. It For example, when the game ball wins the first starting opening 12, the small hit game may be executed without executing the first big hit determination. In addition, when the game ball wins the second starting opening 13, the small hit game may be executed without executing the second big hit determination.

A specific area such as the specific area 272 provided inside the third special winning opening 27 may be provided inside the first special winning opening 16 of the above-described embodiment. In this case, the jackpot game executed using the first big winning opening 16 is one of the game balls winning the first big winning opening 16 in the small hitting game executed using the first big winning opening 16. May be executed subsequent to the small hit game, provided that the game passes through the specific area.

The specific area 272 in the above-described modified example may function as an area that determines whether or not to continue the operation of the accessory continuous operation device. Specifically, it is assumed that the jackpot game is started when one of the game balls winning the third big winning opening 27 in the jackpot game passes through the specific area 272. The pachinko machine 100 starts a new jackpot round after the jackpot round ends, provided that the game ball winning the third jackpot 27 in the jackpot round of the jackpot game passes through the specific area 272. Good.

After the jackpot game is over, a so-called time saving state may be set in which the gaming balls are more likely to win the electric chew 11 than in the normal gaming state. Specifically, after all or part of the jackpot game, a game state in which a game ball is more likely to be won in the electric chew 11 than in a normal game state may be set for a predetermined period. Because of the setting of the time saving state, the variation time of the normal symbol is shortened compared to the state of the normal game, the normal hit is changed to the open pattern of the electric chew so that the electric chew is opened for a longer time in the normal play One or more of the methods such as increasing the probability may be used. In the time saving state, the variation time of the special symbol may be shorter than that in the normal game state. In this case, a change in game occurs such that the execution frequency of the jackpot determination in the time saving state is higher than the execution frequency in the normal game state.

In the above embodiment, the expected value of the profit given to the player when the jackpot game is executed as the result of the second jackpot determination is the expected value to the player when the jackpot game is executed as the result of the first jackpot determination. It is larger than the expected value of the profit to be given. The expected value of the profit given to the player when the jackpot game is executed as a result of the second jackpot judgment, the profit value given to the player when the jackpot game is executed as a result of the first jackpot judgment Various methods can be adopted for making the value larger than the expected value. For example, the size of the entrance of the second jackpot opening 17 used in the jackpot game executed as a result of the second jackpot determination, the first jackpot opening used in the jackpot game executed as a result of the first jackpot determination It may be larger than the size of the 16 inlets. Further, the opening time of the second jackpot opening 17 in the jackpot game jackpot round executed as a result of the second jackpot determination, the first jackpot opening in the jackpot game jackpot round executed as a result of the first jackpot determination It may be longer than the opening time of 16. The total opening time of the second jackpot opening 17 in the jackpot game executed as a result of the second jackpot determination, the total opening time of the first jackpot opening 16 in the jackpot game executed as a result of the first jackpot determination May be longer than. The number of award balls per game ball winning the second major winning opening 17 may be greater than the number of award balls per gaming ball winning the first major winning opening 16. The number of possible second prizes may be greater than the number of possible first prizes. One of these methods may be used, or a plurality of methods may be used in combination.

The first pattern P1 and the second pattern P2, which are the electric chew opening patterns shown in FIG. 7, are examples, and various kinds of opening times, opening times, and opening timings in each electric chew opening pattern can be adopted. It suffices that the game ball that has won the electric chute 11 opened in the first pattern P1 passes through the first passing area 192 more easily than the second passing area 193. In addition, it is only necessary that the gaming balls that have won the electric chute 11 opened in the second pattern P2 pass through the second passing area 193 more easily than the first passing area 192.

In the above-described embodiment and modified example, it is determined in the big hit determination whether the hit is a big hit, a small hit, or a loss. For example, the jackpot determination need not be determined to be a failure.

All elements described in the claims, the description and the drawings (eg display means, moving means, corresponding images, etc.) are physically single unless stated explicitly to limit the number. Alternatively, a plurality of them may be provided, and the arrangement may be changed appropriately. Further, the names given to the elements (element names) are merely given for convenience of description of the present case, and it is not particularly conscious that the names have a special meaning. Therefore, the element name alone does not limit the interpretation of what the element is. For example, the "main substrate" may be hardware alone or may include software. Further, it is a matter that a person skilled in the art can easily consider whether a plurality of elements among all the above elements are appropriately integrally formed or one element is divided into a plurality of elements. It is clear that all patterns are within the expected range without intentionally describing all patterns in the description, etc., and therefore it is stated in the claims etc. that they are explicitly excluded. It goes without saying that all of them are included in the scope of rights according to the present invention unless otherwise stated. Therefore, only by adopting the game machine with the structural difference within the range of the degree because it is not described in this embodiment, the right according to the present invention cannot be avoided. .. In addition, the same applies to the differences in the configurations, shapes, and the like of the respective elements, which are obvious to those skilled in the art from the present embodiment.
