A specific area is provided inside a V-attacker that is opened only during a jackpot game. The “probability short time state” is generated only when the probability change jackpot is determined in the jackpot determination and the game ball passes through the specific area. The open pattern of the V attacker includes a long open pattern and a short open pattern. In the short-time release pattern, it is more difficult to pass the game ball to the specific area than in the case of the long-time release pattern. The rate at which the V-attacker is opened and closed in an open pattern for a long time differs between when the first jackpot determination is determined to be a jackpot and when the second jackpot determination is determined to be a jackpot.

Description

  The present invention relates to a gaming machine that causes a gaming state advantageous to a player by satisfying a specific condition.

  2. Description of the Related Art Conventionally, there are known gaming machines that have different probabilities of transition to a gaming state advantageous to an advantageous player after the jackpot game ends depending on each of a plurality of jackpot determination means. For example, the gaming machine disclosed in Patent Document 1 has a first jackpot determining means for determining a jackpot when a game ball is won at the first starting port, and a jackpot when the game ball is won at the second starting port. A second jackpot determining means for performing determination. The probability of transitioning to the probability variation short-time state, which is the most advantageous gaming state for the player, is 136/251 when determined as a big hit by the first jackpot determining means, but determined as a big hit by the second jackpot determination. In this case, it is 166/251.

  In the conventional gaming machine, the probability variation state is generated after the jackpot game is ended, only on the condition that the probability variation jackpot is a jackpot for shifting to the probability variation state. That is, the rate of occurrence of the probability variation state is the same as the rate of probability variation jackpot. Therefore, when changing the rate of transition to the probability variation state between a plurality of jackpot determinations, the content of the game cannot be easily diversified under the restriction of the rate of probability variation jackpot.

  The present invention can change the rate of transition to the probability variation state between a plurality of jackpot determinations without being restricted by the rate of probability variation jackpot, and can easily diversify game contents The purpose is to provide a machine.

The gaming machine according to the present invention includes a first start port provided on the game board, a first start port detecting means for detecting a game ball won in the first start port, and the first start port detecting means. Due to the fact that a game ball has been detected, first jackpot determination means for determining whether or not to execute a jackpot game that is advantageous to the player, a second start port provided on the game board, A second start port detecting means for detecting a game ball won in the second start port, and whether or not to execute the jackpot game due to the detection of the game ball by the second start port detecting means; A second jackpot determining means for determining, a special winning opening having an opening / closing member, and allowing a game ball to be awarded only when the opening / closing member is opened, and the first jackpot determining means or the second jackpot determining The jackpot game is realized by means. Type determination means for determining whether or not the type of jackpot is a predetermined probability variation jackpot, and the first jackpot determination means or the second jackpot determination means when it is determined that the jackpot is the determination result A determination means for determining an opening pattern of the special winning opening, a notification means for notifying a player of the determination results of the first jackpot determination and the second jackpot determination, and the notification A special winning opening opening / closing means for opening and closing the opening / closing member of the special winning opening according to the opening pattern determined by the determining means during the jackpot game executed after the jackpot is notified by the means; and winning the special winning opening Specific area detecting means for detecting a game ball that has passed through a specific area through which only the played game ball can pass, and the type determination The probability that the first jackpot determination means and the second jackpot determination means determine the jackpot is determined on the condition that the stage is determined to be a probability variation jackpot and the game ball is detected by the specific area detection means. A first advantageous state that occurs after the end of the jackpot game has a first advantageous state that is higher than a normal probability, and a case where the first jackpot determination unit determines that the jackpot is a big hit; and the second jackpot The rate at which the type determining unit determines that the probability variation jackpot is the same when the determining unit determines that it is a big hit, and the opening pattern of the special winning opening includes a game ball to the specific area A long-time opening pattern that allows easy passage of light, and the opening time is shorter than the opening time of the long-time opening pattern, The determination means when it is determined that the probability determination jackpot is determined by the type determination means, including a short-time release pattern in which passing of the game ball to the area is more difficult than during the release by the long-time release pattern. the ratio of long open pattern is determined, and if it is determined that the jackpot by the first jackpot determination means, by different between when it is determined that the jackpot by said second jackpot determination means by said first The ratio at which the first advantageous state is generated by the advantageous state generating means is different between the case where the first big hit determining means is determined to be a big hit and the case where the second big hit determining means is determined to be a big hit. And

In the gaming machine according to the present invention, in order for the first advantageous state to occur after the jackpot game is finished, the probability variation is a big hit and the game ball needs to pass through a specific area. Furthermore, when a game ball wins the first starting port and is determined to be a jackpot (in the case of the first jackpot), and when a game ball wins the second start port and is determined to be a jackpot (the second jackpot) ) And the probability that the game ball will pass through the specific area is different. Therefore, the ratio of shifting to the first advantageous state can be easily changed between the two jackpot determinations without being restricted by the ratio of the probability variation jackpot. In other words , without changing the ratio of probability variation jackpot between the first jackpot judgment and the second jackpot judgment, the ratio at which the first advantageous state occurs is the case of the first jackpot and the second jackpot It can also be changed.

  The second starting port may have an opening / closing member, and the opening / closing member may be opened to allow or facilitate winning of a game ball to the second starting port. The gaming machine is caused by a passage opening provided on the gaming board, passage opening detection means for detecting a game ball that has passed through the passage opening, and detection of a game ball by the passage opening detection means. A normal hit determination means for determining whether or not to execute a normal hit game advantageous to the player, and a second start port opening / closing means for opening and closing the opening and closing member of the second start port during the normal hit game. Further, it may be provided. The first advantageous state may be a short time state of a probability variation in which a rate at which the opening / closing member of the second starting port is opened by the second starting port opening / closing means is higher than usual. In this case, when the probability variation short-time state occurs, the frequency at which the jackpot determination by the second jackpot determination means is increased as compared with the normal state (non-probability variation non-time short state). As described above, the rate at which the probability variation state occurs is different between the case of the first jackpot and the case of the second jackpot. Therefore, the gaming machine according to the present invention can change the probability of transition from the normal state to the probability variation short-time state and the probability that the probability variation state continues without causing the probability variation non-short-time state.

  When the determination unit determines that the probability variation jackpot is determined by the type determination unit, if the first jackpot determination unit determines that the jackpot is one of the long-time release pattern and the short-time release pattern If the second jackpot determination means determines that the jackpot is big, only the long-time opening pattern may be determined. In this case, if it is determined that the probability variation jackpot is determined by the second jackpot determination means, the special winning opening is always opened for a long time, so that the probability variation short time state is likely to occur again thereafter. In other words, during the normal state, it is difficult to shift to the short state at the time of probability change, but once the short state at the time of probability change occurs, the big hit game and the short state at the time of probability change are likely to continue alternately. Therefore, it is possible to entertain the game while making the player strongly expect to shift to the short state when the probability change.

  The average of the notification time when the notification means notifies the determination result of the first jackpot determination is greater when the probability variation short-time state has occurred than when the probability variation short-time state has not occurred. It may be long. In this case, if the short-term probability variation state has occurred, it becomes easier to win the game ball at the second starting port while the determination result of the first jackpot determination is informed. As a result, it is possible to reduce a possibility that the first big hit is determined during the probability variation short state and the continuation of the probability variation short state is interrupted.

  The notification means determines the determination result of the second jackpot determination means when both the determination result of the first jackpot determination means and the determination result of the second jackpot determination means have not been notified to the player yet. Notification may be given with priority over the determination result of the big hit determination means. By giving priority to the determination result of the second jackpot determination, it is possible to reduce the possibility that the first big hit is determined during the probability variation short state and the continuation of the probability variation short state is interrupted.

  The probability that the first jackpot determination means and the second jackpot determination means determine the jackpot is the normal probability when no game ball is detected by the specific area detection means during the jackpot game, and In the non-stochastic variation short time state in which the opening / closing member of the second start opening is higher than usual, the jackpot determination by the first jackpot determination means and the second jackpot determination means is performed after the jackpot game ends. You may further provide the 2nd advantageous state generation means which occurs until it performs predetermined times. Even if the game ball does not pass through the specific area during the jackpot game, the rate at which the second jackpot determination is executed after the jackpot game ends is high. If it is determined that the big jackpot is determined to be a big jackpot, a probability variation short time state is likely to occur thereafter. Therefore, even if the probability variation short-time state is not generated after the jackpot game is completed, the player can continue the game while strongly expecting that the probability variation short-time state is determined again and the probability variation short-time state is generated.

  Hereinafter, a pachinko machine 1 which is an embodiment of a gaming machine according to the present invention will be described with reference to the drawings. First, the mechanical configuration of the pachinko machine 1 will be described with reference to FIGS. 1 to 3.

  As shown in FIG. 1, a game board 2 is provided in the upper half of the pachinko machine 1. The game board 2 is substantially square (see FIG. 2), and the front surface is protected by a glass frame 13 holding a transparent glass plate. An upper plate 5 is provided at the lower part of the game board 2. The upper plate 5 supplies game balls to the launcher and receives prize balls. A lower plate 6 for receiving a prize ball is provided immediately below the upper plate 5. On the right side of the lower plate 6, a launch handle 7 for adjusting the launch of the game ball is provided. Speakers 48 are respectively provided on the left and right corners of the upper portion of the glass frame 13.

  As shown in FIG. 2, a substantially circular game area 4 surrounded by a guide rail 3 is formed on the front surface of the game board 2. An effect device 30 is provided in the approximate center of the game area 4. The effect device 30 performs various effects by driving the decorative body using power such as a motor and causing a light emitter such as an LED to emit light. A display screen 28 composed of an LCD is disposed at the center of the effect device 30. The display screen 28 displays various videos such as moving images and messages. In particular, the display screen 28 displays a demo symbol for notifying the result of the jackpot determination. The player can grasp the result of the jackpot determination through the display screen 28 and the effect device 30.

  Below the display screen 28, a first special symbol start winning opening 14 is provided. A normal symbol start gate 12 is provided on the right side of the display screen 28, and a second special symbol start electric accessory 15 is disposed below the normal symbol start gate 12. A normal attacker 16 and a V attacker 17 are provided vertically below the second special symbol starting electric member 15 diagonally to the left.

  The second special symbol starting electric member 15 includes an opening / closing member. The opening / closing member of the second special symbol starter electric accessory 15 can move in the front-rear direction, and the game ball wins the second special symbol starter electric accessory 15 only when the opening / closing member moves forward (open state). it can. The normal attacker 16 and the V attacker 17 also include an opening / closing member. The opening / closing members of the normal attacker 16 and the V attacker 17 can swing in the front-rear direction around the lower end. The game ball can win the normal attacker 16 and the V attacker 17 only when the open / close member swings forward (open state). Each open / close member is electrically opened and closed by a solenoid.

  As shown in FIG. 3, a specific area 18 and a non-specific area 19 are formed in the flow path of the game ball won in the V attacker 17. The specific region 18 is provided upstream of the non-specific region 19 in the flow path. Furthermore, a lid member 20 that opens and closes the upper opening of the specific region 18 is provided inside the V attacker 17. The lid member 20 can move to a closed position that is an upper part of the specific region 18 and an open position (a position shown in FIG. 3) that is a position to the right of the closed position. If the lid member 20 is in the closed position, the game ball cannot pass through the specific area 18 and passes through the non-specific area 19. If the lid member 20 is in the open position, the game ball passes through the specific area 18 upstream of the non-specific area 19 with a high probability.

  As will be described in detail later, in the pachinko machine 1, during the jackpot game, passing the game ball through the specific area 18 in the V-attacker 17 is one of the conditions for causing the probability variation short-time state after the jackpot game ends. . In the present embodiment, the V attacker 17 is released once during one big hit game. The opening pattern of the V attacker 17 includes a long-time opening pattern that is opened for a maximum of 13 seconds in one opening operation and a short-time opening pattern that is opened only for a maximum of 0.3 seconds. The maximum opening time of the V attacker 17 in the case of the short-time opening pattern is set to a time shorter than the game ball firing interval. Therefore, in the case of a short-time release pattern, the probability that a game ball wins the V attacker 17 is low. The types of jackpot games are provided with a long-time opening jackpot in which a long-time opening pattern is selected and a short-time opening jackpot in which a short-time opening pattern is selected.

  Furthermore, the lid member 20 that closes the specific region 18 moves to the open position only at a predetermined timing. Specifically, the lid member 20 moves to the open position simultaneously with the opening of the V attacker 17 and once returns to the closed position after 0.3 seconds. Then, after 3.5 seconds have passed since the V-attacker 17 is opened, the position moves again to the open position, and returns to the closed position again after 12.5 seconds (16 seconds after the V-attacker is opened). Accordingly, in the case of a big hit for a short time, the time zone during which the game ball can pass through the specific area 18 is only 0.3 seconds when the specific area 18 is first opened. In addition, as shown in FIG. 3, the game ball needs to pass through a flow path of a certain distance from flowing into the entrance of the V attacker 17 until reaching the specific region 18. The flow path is designed so that the average time from the game ball to the specific area 18 from the entrance of the V attacker 17 is longer than 0.3 seconds. That is, in the case of a short-open big hit, the probability that the game ball wins the V attacker 17 is lower than in the case of a long-open big hit, and the game ball won in the V attacker 17 passes through the specific area 18. Probability is also low. Therefore, the probability that the game ball passes through the specific area 18 in the case of a short-open big hit is significantly lower than that in the case of a long-time big hit.

  As shown in FIGS. 1 and 2, a symbol display device 8 is provided diagonally to the right of the game area 4. The symbol display device 8 includes a normal symbol display unit 24, a first special symbol display unit 25, a second special symbol display unit 26, a normal symbol memory number display LED 59, a first special symbol memory number display LED 60, and a second special symbol memory. Number display LED61 (refer FIG. 4) etc. are provided.

  An LED is used for the normal symbol display unit 24. When the game ball passes through the normal symbol start gate 12, a normal hit determination is performed, and the determination result is displayed on the normal symbol display unit 24. The normal symbol display unit 24 displays a normal winning when it is turned on, displays a deviation when it is turned off, and blinks to indicate that the normal symbol is changing. The first special symbol display unit 25 and the second special symbol display unit 26 display special symbols composed of alphabets, numbers, symbols, or combinations thereof. When a game ball wins the first special symbol start winning opening 14, a first jackpot determination is performed, and one of a plurality of special symbols is displayed on the first special symbol display unit 25 according to the determination result. . When a game ball wins the second special symbol start electric accessory 15, a second jackpot determination is performed, and the determination result is displayed on the second special symbol display unit 26.

  The normal symbol memory number display LED 59 displays up to four normal symbol operation reserved balls. The normal symbol actuated holding ball number is the number of game balls that have passed through the normal symbol start gate 12 and whose normal hit determination result is not yet displayed on the normal symbol display unit 24. The first special symbol memory number display LED 60 displays up to four first special symbol actuated balls. The number of first special symbol actuated reserved balls is the number of game balls that have won the first special symbol start winning opening 14 and for which the result of the first jackpot determination has not yet been displayed. The second special symbol memory number display LED 61 displays up to four second special symbol actuated balls. The second special symbol actuated holding ball number is the number of game balls that have won the second special symbol starting electric player 15 and the result of the second jackpot determination is not yet displayed.

  Next, a game flow in the pachinko machine 1 of the present embodiment will be schematically described. The pachinko machine 1 can cause a non-probability variation state in which the probability of being determined to be a big hit in the first jackpot determination and the second jackpot determination is approximately 1/350, and a probability variation state in which the probability is approximately 1/35. . Further, it is possible to cause a non-short-time state in which the opening / closing member of the second special symbol starting electric accessory 15 is a normal rate and a short-time state in which the rate is higher than the non-time-short state. With these combinations, the pachinko machine 1 has three game states of “non-probability variation non-short state” (hereinafter referred to as “normal state”), “non-probability variation short state”, and “probability variation short state”. Occur. Needless to say, the type of gaming state in which the pachinko machine 1 can occur can be changed. For example, the present invention can also be applied to a pachinko machine that can generate only two game states of “normal state” and “probability short state”.

  The “non-probability short time state” ends when the sum of the number of first jackpot determinations and the number of second jackpot determinations reaches a specified number (100 in this embodiment), and shifts to the “normal state”. . Therefore, the player plays a game in the hope that it will be a big hit before the “non-probability short time state” ends. The “probability short time state” ends when the sum of the number of jackpot determinations reaches 10,000. However, since the probability of being determined to be a big hit in the “short state at the time of probability change” is about 1/35, the possibility that it will be determined to be out of 10000 consecutive times is close to zero. Therefore, the “probability change short state” of the present embodiment is practically continued until it is determined that the next jackpot. The “non-probability short time state” and “probability short time state” are also ended when the jackpot game is started. In this case, the specified number of counts is cleared.

  During the “normal state”, the rate at which the opening / closing member of the second special symbol starter electric accessory 15 is opened is lower than in the time-short state. Therefore, the player can easily win the game ball in the first special symbol start winning opening 14 than in the second special symbol start electric accessory 15. When a game ball wins the first special symbol start winning opening 14, a first jackpot determination is performed.

  When it is determined that the jackpot is a special symbol indicating that the determination result is a jackpot. The jackpot type is determined according to the determined special symbol. The jackpot type in the present embodiment is first classified into either a probability variation jackpot or a normal jackpot. When the probability variation jackpot is reached, a “probability variation short state” is generated on condition that the game ball passes through the specific area 18 (see FIG. 3). Normally, if the game is a big hit, even if the game ball passes through the specific area 18, the “probability variation short state” does not occur. Further, the jackpot type is classified into one of the above-mentioned long-time opening jackpot and short-time opening jackpot. The pachinko machine 1 is provided with three jackpot types, “probability fluctuation long-time open jackpot”, “probability fluctuation short-time jackpot”, and “normal short-time jackpot” by these combinations. The jackpot type may be changed. For example, the present invention can be realized by using “normally long open big hit”.

  Although details will be described later, when it is determined that the first jackpot is determined to be a jackpot, the ratio of “probability variation long-time open jackpot” is 50%. If “probability variation long open jackpot” is reached, the “probability variation short state” is almost generated after the jackpot game ends. On the other hand, if it is not “probability variation long open big hit”, after the jackpot game ends, almost “non-probability short time state” occurs. That is, the probability of shifting from the “normal state” to the “short state during probability change” via the jackpot game is about 50%.

  During the “probability change short state”, the rate at which the opening / closing member of the second special symbol starting electric accessory 15 is opened is higher than in the “normal state”. Therefore, the player can easily win the game ball with the second special symbol start electric accessory 15 than the first special symbol start winning opening 14, so that the game ball is launched to the right side of the game board 2. (So-called “right-handed”). When a game ball wins the second special symbol start electric accessory 15, a second jackpot determination is performed. When it is determined that the jackpot is determined by the second jackpot determination, the long-time open jackpot is determined at a higher rate than when the jackpot is determined by the first jackpot determination. In the present embodiment, when it is determined that the jackpot is determined by the second jackpot determination, the ratio of “probability variation long-time open jackpot” is 85%. Therefore, in the pachinko machine 1, the probability that the “probability variation short state” continues through the jackpot game is higher than the probability of shifting from the “normal state” to the “probability variation short state”. In other words, in the pachinko machine 1, the rate of transition to the “probability variation short state” can be changed in accordance with the gaming state without differentiating the probability variation probability jackpot between the two jackpot determinations. Since the rate of transition to the “probability variation short-time state” can be changed according to the gaming state without causing the “probability variation non-short-time state”, the game content is not complicated.

  Even during the “non-probability short state”, the opening / closing member of the second special symbol starting electric accessory 15 is easily opened. Therefore, the player makes a right turn. The probability of being determined to be a big hit during the “non-probability fluctuation short state” is lower than in the “probability fluctuation short state”. However, if the result of the second jackpot determination becomes a big hit before the shift to the “normal state” continuously for the specified number of times, the “probability short time state” occurs with a probability of about 85% after the jackpot game ends. . Therefore, in the pachinko machine 1, the player can enjoy the game without impairing the expectation even when the “short state at the time of non-probability change” is generated without the “short state at the time of probability change” occurring. That is, the value of the “non-probability short time state” can be increased as compared with the conventional gaming machine.

  Next, the electrical configuration of the pachinko machine 1 will be described with reference to FIG. As shown in FIG. 4, the control unit 40 includes a main board 41, a sub control board 58, a lamp driver board 46, an effect control board 43, a payout control board 45, and a relay board 47.

The flag relation storage area 5210 stores various flags other than the flags stored in the winning ball flag storage area 5202.

  Next, the storage area of the ROM 53 of the main board 41 will be described. The ROM 53 stores various initial values, programs, and the like. Further, the ROM 53 includes a jackpot determination table for performing the first jackpot determination and the second jackpot determination, a special symbol determination table for determining the first special symbol and the second special symbol, and a variation for determining the variation pattern. A pattern determination table and the like are stored. The variation pattern is a pattern for determining the effect time of the notification effect for notifying each result of the first jackpot determination and the second jackpot determination, and the operation of the display screen 28 and the speaker 48 during the notification effect. .

  The special symbol determination table stored in the ROM 53 will be described with reference to FIG. The pachinko machine 1 has a special symbol determination table including a first jackpot special symbol indicating that the result of the first jackpot determination is a jackpot and a second jackpot special symbol indicating that the result of the second jackpot determination is a jackpot. Determine by referring to. As described above, the jackpot special symbol is classified into either a probability variation jackpot or a normal jackpot. Furthermore, the jackpot type is classified into either a long-time open jackpot or a short-time open jackpot.

  In the pachinko machine 1, it is a condition for causing a “probability variation short state” that the game ball passes through the specific area 18 in the V attacker 17 and becomes a big hit of probability variation. If at least one of the two conditions is not satisfied, after the jackpot game is finished, the “probability variation short state” is not generated, and the “non-probability variation short state” is generated. When the V attacker 17 is opened and closed in a short-time opening pattern, the possibility that the game ball passes through the specific area 18 is very low. Therefore, when the jackpot type is “probability variation short-time open jackpot”, the probability of shifting to the “probability variation short state” is almost zero. If the jackpot type is a normal jackpot (in this embodiment, “normal short-time open jackpot”), the probability of shifting to the “probability change short state” is 0%. The ratio that the jackpot type is “probability variation long-time open jackpot” is almost the same as the ratio of transition to the “probability variation short state”.

  In the pachinko machine 1, the ratio of probability variation jackpots is 85% in both the first jackpot determination and the second jackpot determination. However, when it is determined that the first jackpot is a jackpot, the ratio of “probability fluctuation long-time open jackpot” is 50%. When it is determined that the second jackpot is a jackpot, the ratio of “probability variation long-time open jackpot” is 85%. That is, it is possible to change the rate of transition to the “probability variation short state” without making the rate of probability variation jackpot different between the two jackpot determinations.

  The variation pattern determination table stored in the ROM 53 will be described with reference to FIGS. The pachinko machine 1 stores two variation pattern determination tables, a first special symbol variation pattern determination table (see FIG. 7) and a second special symbol variation pattern determination table (see FIG. 8). The first special symbol variation pattern determination table is referred to in order to determine a variation pattern when notifying the result of the first jackpot determination. The second special symbol variation pattern determination table is referred to in order to determine a variation pattern when notifying the result of the second jackpot determination.

  Each of the first special symbol variation pattern determination table and the second special symbol variation pattern determination table includes a plurality of tables according to the gaming state at the time of jackpot determination and the result of the jackpot determination. Each table is assigned a plurality of types of variation patterns, and each variation pattern is associated with a variation pattern determination random number value (0 to 511). When the jackpot determination is performed, a table corresponding to the type of jackpot determination, the gaming state, and the determination result is referred to, and one variation pattern is determined based on the acquired variation pattern determination random number value. The main board 41 transmits a command specifying the determined variation pattern to the sub-control board 58. The sub-control board 58 controls the display screen 28, the speaker 48, and the like according to the designated variation pattern. Further, the main board 41 changes the special symbol display portions 25 and 26 for the change time determined according to the determined change pattern.

  As shown in FIGS. 7 and 8, the variation times of the variation patterns other than “non-reach” are all the same regardless of the type of jackpot determination and the gaming state. As shown in FIG. 7, the variation time of “non-reach” in the “non-stochastic variation non-short-time state” in the first jackpot determination is 10 seconds when the number of retained balls is “0”, and the number of retained balls is “1 or 2”. "Is 8 seconds, and when the number of reserved balls is" 3-8 ", it is 6 seconds. On the other hand, the variation time of “non-reach” in the “non-probability short state / probability short state” is 11 seconds when the number of reserved balls is “0” and 9 times when the number of held balls is “1 or 2”. Second, 7 seconds when the number of reserved balls is “3-8”. In other words, the average of the non-reach variation time in the non-probability short state / probability short state is the average of the non-reach variation time in the non-probability non-short state (normal state). 1 second longer. Accordingly, during the “non-stochastic variation short state / probability variation short state”, the variation time for notifying the result of the first jackpot determination becomes long, and during this notification time, the second special symbol start electric accessory 15 is informed. It becomes easy to win game balls.

  Furthermore, as shown in FIG. 8, the variation time of “non-reach” in the “non-probability variation short state / probability variation short state” in the second jackpot determination is 10 seconds when the number of reserved balls is “0”, It is 4 seconds when the number of reserved balls is “1 or 2”, and 3 seconds when the number of reserved balls is “3-8”. In other words, the average of the variation time of “non-reach” in “non-probability short state / probability short state” indicates the result of the first jackpot determination when the second jackpot determination result is reported. Shorter than the case. Accordingly, during the “non-stochastic change short state / probability change short state”, the result of the second jackpot determination is notified in a short time, and the first jackpot determination result takes a long time. As a result, the possibility that the first jackpot determination is performed during the “non-probability short state / probability short state” is reduced.

  Next, the operation of the main board 41 of the pachinko machine 1 will be described with reference to FIGS. The main control of the pachinko machine 1 is performed by a control program stored in the ROM 53. The main process of the control program is executed in the CPU 51 when the CPU 51 detects an interrupt signal generated every 4 ms by the interrupt signal generation circuit 57 (see FIG. 4). Hereinafter, each step of the flowchart is abbreviated as “S”.

  First, command output processing is performed (S10). In the command output process, a 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 a control command stored in the RAM 52 in the main process executed last time.

  Next, a switch reading process is performed (S11). In the switch reading process, a process for detecting a game ball is performed from the detection results of each switch (see FIG. 4) provided in the normal symbol start gate 12, each winning opening, the specific area 18, and the non-specific area 19. Is called.

  Next, a counter update process is performed (S12). In the counter update process, the value of the random number acquisition counter stored in the RAM 52 is added, and the value of the timer counter is subtracted.

  Next, special electric accessory processing is performed (S13). In the special electric accessory process, a process for controlling the operation of the jackpot game and a process related to a game state that occurs after the jackpot game is finished are performed (see FIG. 14).

  Next, special symbol processing is performed (S14). In the special symbol processing, jackpot determination, determination of special symbols, game state transition processing, and the like are performed (see FIGS. 10 to 13).

  Next, ordinary electric accessory processing is performed (S15). In the ordinary electric accessory process, a process for controlling the operation of the normal hit game is performed when the normal hit is reached. CPU51 will open the 2nd special symbol starting electrically-driven accessory 15 longer than in a non-time-short state, if the time-short state has arisen. Note that if the time reduction flag is set to “ON”, the CPU 51 determines that it is in the time reduction state.

  Next, normal symbol processing is performed (S16). In the normal symbol processing, a normal hit random number is acquired when the normal symbol operation switch 74 detects a game ball. Based on the acquired random number, processing such as ordinary hit determination, storage of commands for controlling fluctuations in ordinary symbols, and the like are performed. The probability (99/100) that is determined to be a normal hit during the short-time state is higher than the probability (50/100) that is determined to be a normal hit during the non-time-short state. The variation time of the normal symbol is shorter in the time-short state than in the non-time-short state.

  Next, a payout process (S17), an error check (S18), and an information output process (S19) are performed. In the payout process, the payout of prize balls is controlled. In the error check, when an error occurs, the error is notified using the display screen 28, the speaker 48, and the like. In the information output process, various types of information are output to a game hall management computer (not shown).

  Details of the special symbol process (S14) will be described with reference to FIGS. First, flags used in special symbol processing will be described. The flag-related storage area 5210 (see FIG. 5) of the RAM 52 stores a jackpot gaming state flag, a special symbol display state flag, a probability variation flag, a time reduction flag, and the like. The jackpot game state flag is “ON” when “1” is stored during the jackpot game, and “0” is stored and “OFF” when the jackpot game is not played. The special symbol display state flag is “1” when either one of the two special symbol display portions 25 and 26 is changing (during change), and when one of them is stopped (during stop display). “2”, “0” is stored when neither of them is changing nor being stopped. The probability variation flag is set to “ON” by storing “1” during the probability variation state. The time reduction flag is set to “ON” by storing “1” during the time reduction state.

  As shown in FIG. 9, when the special symbol process is started, it is determined whether or not a game ball is won in the first special symbol start winning opening 14 (S21). When the first start switch 72 provided in the first special symbol start winning opening 14 detects the winning of the game ball, the first of the winning ball flag storage area 5202 in the main process switch reading process (S11, see FIG. 9). The flag corresponding to the start switch 72 is set to “ON”. If this flag is not “ON” and the game ball has not won (S21: NO), the process directly proceeds to the determination of S25. If a game ball has won the first special symbol start winning opening 14 (S21: YES), it is determined whether or not the value of the first special symbol actuated holding ball number storage area 5206 is "4" ( S22). If it is “4” (S22: YES), the number of suspendable balls that can be stored has reached the upper limit, and the process directly proceeds to the determination of S25.

  When the number of first special symbol operation reservation balls is not “4” (S22: NO), “1” is added to the value of the first special symbol operation reservation balls number storage area 5206 (S23). Next, a random number is stored in the first jackpot relation information storage area 5205 (S24). Specifically, the value of the first jackpot determination counter is stored in the first jackpot random number column of the first jackpot relation information storage area 5205. The value of the first special symbol determination counter is stored in the first jackpot special symbol determination random number column, and the value of the first variation pattern determination counter is stored in the first variation pattern determination random number column.

  Next, processing related to winning a game ball to the second special symbol starting electric accessory 15 is performed. First, it is determined whether or not a game ball has won the second special symbol start electric accessory 15 (S25). When it is determined that the flag corresponding to the second start switch 73 provided on the second special symbol start electric accessory 15 is “OFF” and the game ball is not won (S25: NO). Then, the process directly proceeds to the determination of S31 (see FIG. 11). If a game ball has won the second special symbol start electric accessory 15 (S25: YES), it is determined whether or not the value of the second special symbol actuated holding ball number storage area 5208 is "4". (S26). If it is “4” (S26: YES), since the random number for this game ball cannot be stored, the process proceeds to the determination of S31 as it is.

  If the second special symbol operation reserved ball number is not “4” (S26: NO), “1” is added to the value of the second special symbol operation reserved ball number storage area 5208 (S27). Various random numbers are stored in the second jackpot relation information storage area 5207 (S28), and the process proceeds to the determination of S31.

  Next, as shown in FIG. 11, it is determined whether or not the game state is a jackpot gaming state (S31). If the jackpot gaming state flag is “ON” and it is determined that the jackpot gaming state is in effect (S31: YES), the processing returns to the main processing as it is. If it is not in the big hit gaming state (S31: NO), it is determined whether any of the two special symbol display portions 25, 26 is changing (S32). If the display state flag is not “1” and neither of them is changing (S32: NO), it is determined whether or not one of the two special symbol display units 25 and 26 is stopped (S33). ). If the display status flag is not “2” and none of them is being stopped (S33: NO), the process proceeds to S34 (see FIG. 12), and a big hit determination is performed.

  In the jackpot determination, the second jackpot determination is performed with priority over the first jackpot determination. As shown in FIG. 12, first, it is determined whether or not the number of second special symbol actuated holding balls is “1” or more (S34). If it is “1” or more and the second special symbol operation holding ball is present (S34: YES), the second jackpot determination is performed, which will be described in detail later. If the number of the second special symbol operation reservation balls is “0” (S34: NO), it is determined whether or not the number of the first special symbol operation reservation balls is “1” or more (S35). If it is “0” (S35: NO), the process directly returns to the main process.

  If the number of the first special symbol operation reservation balls is “1” or more (S35: YES), the value of the first special symbol operation reservation balls number storage area 5206 is subtracted from “1” (S36), and the first jackpot determination Is performed (S37). The first jackpot determination is performed based on the value in the first jackpot random number column of the first jackpot relation information storage area 5205 with reference to a determination table according to whether or not the probability variation state is in effect. Next, in the first special symbol variation pattern determination table (see FIG. 7), the variation pattern is determined by a table corresponding to the gaming state and the determination result. Furthermore, a special symbol is determined. Specifically, if the determination result is a jackpot (S38: YES), one of the variation patterns indicating the first jackpot is determined by the value in the first variation pattern determination random number column (S39). When the variation pattern is determined, a process of starting a notification effect according to the determined variation pattern is performed, and the variation of the special symbol is started. Next, according to the special symbol determination table (see FIG. 6), one of the first special symbols indicating the first jackpot is determined based on the value of the first jackpot special symbol determination random number column (S40). As described above, the jackpot type is determined according to the special symbol. The process proceeds to S52. If the determination result is out of order (S38: NO), one of the variation patterns indicating the outage is determined (S41), and the process proceeds to S52. The special symbol in the case of a loss is one type of “-”.

  In addition, when the second special symbol operation holding ball exists (S34: YES), the second jackpot determination is performed in the same flow as the first jackpot determination. First, “1” is subtracted from the value of the second special symbol operation reserved ball number storage area 5208 (S43), and a second jackpot determination is made according to whether or not the probability variation state is being performed (S44). If the jackpot (S45: YES), the second special symbol variation pattern determination table (see FIG. 8) is referred to determine the variation pattern indicating the second jackpot (S46). A second special symbol indicating the presence is determined (S47), and the process proceeds to S52. If the determination result is out of order (S45: NO), the variation pattern indicating the out of place is determined (S48), and the process proceeds to S52.

  When the big hit determination is completed, the variation time of the special symbol determined according to the determined variation pattern is set in the special symbol variation time counter which is a timer counter (S52). “1” indicating that one of the special symbol display units 25 and 26 is changing is stored in the special symbol display state flag (S53), and the process returns to the main process.

  Further, in the determination of S32 shown in FIG. 11, when “1” is stored in the special symbol display state flag and it is determined that any of the special symbol display portions 25 and 26 is changing (S32). : YES), it is determined whether or not the variation time has elapsed (S54). If the value of the special symbol variation time counter set in S52 (see FIG. 12) is “0” and it is determined that the variation time has elapsed (S54: YES), a special symbol stop command is stored in the RAM 52. Is stored (S55). This command is transmitted to the sub-control board 58 and the relay board 47 in the next main process, and instructs the demo symbols on the display screen 28 and the fluctuation stop of the special symbol display units 25 and 26. Next, a predetermined stop display time (for example, 0.6 seconds) is stored in the special symbol stop time counter (S56). “2” indicating that one of the special symbol display sections 25 and 26 is in a stopped display is stored in the special symbol display state flag (S57), and the process returns to the main process. On the other hand, if it is determined in S54 that the variation time has not yet elapsed (S54: NO), the process returns to the main process as it is.

  If it is determined in S33 that “2” is stored in the special symbol display state flag and one of the special symbol display units 25 and 26 is determined to be stopped (S33: YES). Whether or not the stop display time has elapsed is determined based on the value of the counter set in S56 (S59). If the value of the special symbol stop time counter is not “0” and the stop display time has not yet elapsed (S59: NO), the process returns to the main process as it is. When the stop display time has elapsed (S59: YES), “0” indicating that neither the special symbol display units 25 and 26 are changing nor being stopped is stored in the special symbol display state flag (S60). . Next, a game state transition process is performed (S61), and the process returns to the main process.

  With reference to FIG. 13, the gaming state transition process will be described in detail. In the game state transition process, control of a flag for shifting to a jackpot game when it is determined that the jackpot is determined, and control of a flag for ending the short-time state and the probability variation state are performed. First, it is determined whether or not the jackpot determination result is a jackpot (S63). If it is a jackpot (S63: YES), the value of the jackpot determination count counter that counts the number of jackpot determinations made after the end of the previous jackpot game (number of times determined to be consecutively lost) is initialized. (S64). “1” indicating that the jackpot game is being played is stored in the jackpot game state flag and set to “ON” (S65). Both the probability variation flag and the time reduction flag are set to “OFF” (S66), and the process returns to the special symbol process.

  If the jackpot determination result is not a jackpot (S63: NO), “1” is added to the value of the jackpot determination count counter (S68). Next, it is determined whether or not a “non-probability short time state” has occurred (S69). If the “non-probability short time state” has occurred (S69: YES), whether or not the number of determinations has reached 100 is determined based on the value of the jackpot determination number counter (S70). If it has not reached 100 times (S70: NO), the process returns to the special symbol process (see FIG. 11) as it is. When it reaches 100 times (S70: YES), the time reduction flag is set to “OFF” (S71), and the process returns to the special symbol process. That is, the gaming state shifts from the “non-probability short time state” to the “normal state”.

  If the “non-probability short time state” has not occurred (S69: NO), it is determined whether or not the “probability short time state” has occurred (S73). If it has not occurred, that is, if the “normal state” has occurred (S73: NO), the process directly returns to the special symbol process. If the “probability variation short state” has occurred (S73: YES), it is determined whether the number of determinations reaches 10,000 based on the value of the jackpot determination number counter (S74). If it has not reached 10,000 times (S74: NO), the process returns to the special symbol process as it is. If it has reached 10,000 times (S74: YES), both the probability variation flag and the hourly flag are set to “OFF” (S75), and the process returns to the special symbol process.

  Next, with reference to FIG. 14, the details of the special electric accessory processing (see S13, FIG. 9) will be described. First, the flag used in the special electric accessory processing will be described. The main flags used here include an open flag and a processing standby flag. The open flag is a flag indicating whether or not one of the normal attacker 16 and the V attacker 17 is open. “1” is stored and “ON” is stored during either release, and both are closed. If it is set, “OFF” is set. The process waiting flag is a flag indicating whether or not the waiting time from when one of the normal attacker 16 and the V attacker 17 is closed until the next process is performed is “1” during the waiting time. "Is stored and" ON ".

  As shown in FIG. 14, when the special electric accessory processing is started, it is determined whether or not the jackpot gaming state is set (S101). If the jackpot gaming status flag is “OFF” and it is determined that the jackpot gaming status is not set (S101: NO), the processing returns to the main processing as it is. If it is determined that the game state is a big hit game state (S101: YES), it is determined whether or not it is during the waiting time until the next processing relating to the normal attacker 16 and the V attacker 17 is performed by the processing waiting flag. (S102).

  When it is determined that the processing standby flag is “OFF” and the standby time is not being reached (S102: NO), it is determined whether one of the normal attacker 16 and the V attacker 17 is opened (S102: NO). S103). When the open flag is “OFF” and both the normal attacker 16 and the V attacker 17 are closed (S103: NO), a process for opening either the normal attacker 16 or the V attacker 17 is performed. (S104 to S111). First, “1” is added to the round number counter that counts the number of opening / closing operations of the executed attackers 16 and 17 (S104). Next, based on the value of the round number counter, it is determined whether or not it is the final round (for example, the 15th round among all 15 rounds) (S105). If it is not the final round (S105: NO), a normal attacker release command for releasing the normal attacker 16 is stored in the RAM 52 (S106). A long time open counter for measuring the maximum open time of 13 seconds is set (S109). The open flag is set to “ON” (S111), and the process proceeds to the determination of S113.

  If it is the final round (S105: YES), a V attacker release command for releasing the V attacker 17 is stored in the RAM 52 (S107). At the same time as the V-attacker opening command is stored, a control process (not shown) for opening and closing the lid member 20 (see FIG. 3) according to the above-described procedure is performed. Next, it is determined whether or not the type of jackpot is a long-time open jackpot (in this embodiment, “probability variation long-open jackpot”) (S108). If the long-time open big hit (S108: YES), the long-time open counter is set (S109), the open flag is set to “ON” (S111), and the V attacker 17 is opened and closed in a long open pattern. . If it is a short-open big hit (S108: NO), a short-time open counter that measures a maximum open time of 0.3 seconds is set (S110), an open flag is set to “ON” (S111), and V The attacker 17 is opened and closed in an open pattern for a short time.

  Next, it is determined whether or not the number of game balls won to the opened attackers 16 and 17 is “9” or more (S113). The number of game balls won in the attackers 16 and 17 during one opening operation (during one round) is counted in the switch reading process (S11, see FIG. 9). If the number of winning balls is not “9” or more (S113: NO), it is determined whether or not a maximum opening time of 13 seconds or 0.3 seconds has elapsed (S114). If the maximum opening time has not elapsed (S114: NO), the process returns to the main process as it is. In the case of the special electric game processing performed after that, when the jackpot gaming state is set (S101: YES), not in the waiting time (S102: NO), and the attackers 16 and 17 are open (S103: YES) These determinations are repeated until nine or more game balls win the attackers 16 and 17 or until the maximum opening time has elapsed (S113: NO, S114: NO).

  When 9 or more game balls are won (S113: YES) or when the maximum opening time has elapsed (S114: YES), a closing command for closing the opened normal attacker 16 or V attacker 17 Is stored in the RAM 52 (S115). The predetermined waiting time is stored in the processing waiting time counter (S116). The opening flag is set to “OFF” (S117). “1” indicating the waiting time is stored in the processing waiting flag and is set to “ON” (S118), and the processing returns to the main processing.

  If the processing standby flag is “ON” (S102: YES), it is determined whether or not the standby time has elapsed based on the value of the processing standby time counter (S121). If the value of the counter is not “0” and the standby time is being measured (S121: NO), the process returns to the main process as it is. If time elapses while the main process is repeatedly performed and the standby time elapses (S121: YES), the process standby flag is set to “OFF” (S122).

  Next, whether or not a specified round (for example, 15 rounds) has been consumed is determined based on the value of the round number counter (S123). If the specified round has not been digested (S123: NO), the process returns to the main process, and the opening and closing operations of the attackers 16 and 17 are performed again in the next special electric accessory process. When the specified round is digested (S123: YES), the value of the round number counter is initialized (S124). The jackpot gaming state flag is set to “OFF” (S125).

  Next, a process for generating the “non-probability short state” or the “probability short state” is performed. Specifically, it is first determined whether or not the jackpot type is a probability variation jackpot (S126). When the jackpot type is not the jackpot probability jackpot but the regular jackpot (S126: NO), the “probability change short state” is not generated at that time. Therefore, only the time reduction flag is set to “ON” (S129), a “non-probability change time reduction state” is generated, and the processing returns to the main processing. If the jackpot type is the probability variation jackpot (S126: YES), it is determined whether or not the game ball has passed through the specific area 18 in the V attacker 17 during the jackpot game (S127). When the specific area switch 76 detects a game ball that has passed through the specific area 18, the flag corresponding to the specific area switch 76 in the winning ball flag storage area 5202 is set to “ON” in the switch reading process (S11, see FIG. 9) of the main process. " If this flag is set to “ON” (S127: YES), the probability variation flag is set to “ON” (S128), the time reduction flag is set to “ON” (S129), and “probability variation short time state” is set. Is born. The process returns to the main process. If the game ball has not passed through the specific area 18 (S127: NO), only the time reduction flag is set to “ON” (S129), a “non-probability short time state” is generated, and the process returns to the main process.

  Next, with reference to FIG. 15, the game executed in the pachinko machine 1 will be described. In the pachinko machine 1, the gaming state with the highest percentage of occurrence is the “normal state”. In the “normal state”, the rate at which the opening / closing member of the second special symbol starting electric accessory 15 is opened is low. Therefore, the player adjusts the launch handle 7 so that the game ball flows down on the left side of the display screen 28 (see FIGS. 1 and 2), and makes the game ball win the first special symbol start winning opening 14. As a result, the jackpot determination executed during the “normal state” is almost the first jackpot determination.

  When it is determined that the first jackpot is a jackpot, the ratio of “probability variation long-time open jackpot” is 50%. When “probability variation long open big hit” is satisfied, two conditions (probability variation big hit + passing of specific area 18 of game ball) for generating “probability fluctuation short state” can be easily satisfied. When the two conditions are satisfied, the game state after the jackpot game ends becomes a “probability variation short state”. Even when “probability fluctuation long-time open big hit” is reached, there is very little possibility that the game ball will not pass through the specific area 18. In this case, the gaming state is “short state during non-probability change. Further, when it is determined that the first jackpot is determined to be a big hit, the ratio of“ probability change short-time open big hit ”is 35%. In the case of “probability variation short-time open big hit”, if the game ball passes through the specific area 18, a “probability variation short state” is subsequently generated. However, since the opening time of the V attacker 17 is short, it is difficult for the game ball to pass through the specific area 18. Therefore, in the case of “probability variation short-time open jackpot”, the gaming state after the jackpot game is almost “non-probability variation short state”. Moreover, when it is determined that the jackpot is determined by the first jackpot determination, the ratio of “non-probability variation short-time open jackpot” is 15%. In this case, the gaming state after the end of the jackpot game is always a “non-probability short state”.

  In the present embodiment, the normal attacker 16 and the V attacker 17 are arranged in the lower right portion of the game board 2. Therefore, during the jackpot game, the player launches a game ball to the right part of the game board 2 (so-called “right-handed”). A normal symbol start gate 12 and a second special symbol start electric accessory 15 are also arranged on the right part of the game board 2. A part of the game ball fired to the right part of the game board 2 passes through the normal symbol start gate 12, and the normal hit determination is performed. During the jackpot game state, the short-time state is not generated. While the time-short state is not occurring (during the non-time-short state), at least one of the probability of being determined to be a normal hit, the normal symbol variation time, and the opening time of the second special symbol starter electric accessory 15 is the time-short state. By making it different from the inside, the rate at which the second special symbol starting electric accessory 15 is opened is set lower than in the time-short state. However, in the present embodiment, the probability that it is determined to be a normal hit and the fluctuation of the normal symbol so that, on average, several game balls win the second special symbol starting electric player 15 within the jackpot game time. Time and the opening time of the second special symbol starting electric accessory 15 are set. Therefore, during the jackpot game, the number of second special symbol actuated holding balls increases on average.

  In the “probability change short state”, the ratio of opening the second special symbol starting electric accessory 15 is high. Therefore, the player fires a game ball toward the second special symbol start electric accessory 15 arranged on the right part of the game board 2. The game ball fired to the right part of the game board 2 is difficult to win the first special symbol start winning opening 14. Further, in the present embodiment, when both the first special symbol operation reservation ball and the second special symbol operation reservation ball exist, the second jackpot determination is performed with priority. During the big hit game, several second special symbol actuating balls are stored on average. In addition, during the “probability variation short state”, the effect time of the notification effect indicating the result of the first jackpot determination (the variation time of the symbol of the first special symbol display unit 25) is longer than that in the “normal state”. . As a result, it is easier to win the second special symbol starting electric accessory 15 during the fluctuation of the first special symbol than in the “normal state”. From the above, the jackpot determination executed during the “probability short time state” is almost the second jackpot determination.

  The probability of being determined to be a big hit during the “short state at the time of probability change” is higher than the “normal state” and the “short state at the time of non-probability change”. When it is determined that the jackpot is determined by the second jackpot determination, the ratio of “probability variation long-time open jackpot” increases to 85% compared to the case of the first jackpot determination. In other words, the ratio of the probability change jackpot itself is the same ratio in the first jackpot judgment and the second jackpot judgment, but the ratio that the “probability short time state” occurs after the jackpot game ends is the first jackpot judgment. It differs between the judgment and the second jackpot judgment. Therefore, the pachinko machine 1 can easily change the rate of transition to the probability variation state between the two jackpot determinations without being restricted by the rate of probability variation jackpot.

  In a conventional gaming machine having a plurality of jackpot determination means, there is no difference between a plurality of jackpot determinations in the ratio of the jackpot type, which is a jackpot that shifts to the probability variation state, which is a jackpot transition jackpot . When the probability variation jackpot is reached, a probability variation state is always caused after the jackpot game is over. Therefore, in the conventional gaming machine, it is necessary to always use the “probability variation non-short state” when changing the ratio of transition to the “probability variation short state” between a plurality of jackpot determinations. In other words, the probability that the probability variation itself will occur is the same among multiple jackpot judgments, but there are multiple ratios that cause the “probability variation short-time state” and multiple “probability variation non-short-time states”. By changing between jackpot judgments, a difference is made in the rate of transition to the “probability change short state”. Therefore, there is a restriction that the “probability variation non-short-time state” must be used, and problems such as a complicated game content cannot be solved. On the other hand, in the pachinko machine 1 according to the present embodiment, the ratio of the probability variation jackpot is the same between the two jackpot determinations, but the open pattern selection ratio of the V attacker 17 depends on the type of jackpot determination. Different. Thereby, the ratio which transfers to a probability fluctuation state can be easily changed between two jackpot determinations.

  In the present embodiment, even when it is determined that the probability variation jackpot is determined by the first jackpot determination, there is a case where the short-term release jackpot becomes short and the transition to the “probability variation short state” does not occur. On the other hand, when it is determined that the probability variation jackpot is determined by the second jackpot determination, the jackpot will always be a long-term open jackpot, and then it is easy to shift to the “probability variation short state”. In other words, during the “normal state”, it is difficult to shift to the short state at the time of probability change, but once the “short state at the time of probability change” occurs, the big hit game and the “short state at the time of probability change” are likely to continue alternately. Accordingly, it is possible to entertain the game while making the player strongly expect to shift to the “probability change short state”.

  In the “non-probability short time state”, the probability of being determined to be a jackpot is the same as in the “normal state”, but since the second special symbol starting electric accessory 15 is released at a high rate, the second jackpot determination is high. Done in proportion. As described above, when it is determined that the jackpot is determined by the second jackpot determination, the ratio of “probability long open jackpot” is higher than that in the case of the first jackpot determination (85%). Therefore, even if the “probability short time state” does not occur after the jackpot game ends, the player can enjoy the game while strongly expecting to be determined to be a big hit again during the “non-probability short time state”. And expectation is not lost. That is, the value of the “non-probability short time state” can be increased as compared with the conventional gaming machine.

  As described above, the second jackpot determination is performed at a high rate in the “short state at the time of probability change” and the “short state at the time of non-probability change”. However, even when the short-time state has occurred, there is little possibility that the first jackpot determination will be performed. If the first jackpot judgment is determined to be a big hit during the time-short state, the percentage of “probability fluctuation long-time open big hits” will be lower than if the second jackpot judgment is judged to be a big hit. Can not fully enjoy the benefits. Therefore, in order to prevent the player from being discouraged, it is necessary to reduce the frequency at which the first jackpot determination is performed during the short-time state. As described above, since the pachinko machine 1 employs the priority digestion of the second jackpot determination, the frequency of the second jackpot determination is higher during the short-time state. Then, an average number of second special symbol actuating balls are stored during the jackpot game. Therefore, the second jackpot determination is easily performed immediately after the end of the jackpot game, and the second special symbol start electric motor is performed while the result of the second jackpot determination is being notified (while the second special symbol display unit 26 is changing). If a game ball is awarded to the accessory 15, the game proceeds without the first jackpot determination being made. In addition, the time of the notification effect of the first jackpot determination in the “probability change short state” and the “non-probability change short state” is set longer than that in the “normal state”. Further, the first special symbol start winning opening 14 and the second special symbol start electric accessory 15 are separated in the left-right direction. As a result, it is possible to reduce the frequency at which the first jackpot determination is performed in the “short state at the time of probability change” and the “short state at the time of non-probability change”.

The display screen 28 for executing the notification effect corresponds to “notification means”. The V attacker open / close solenoid 71 corresponds to “special prize opening opening / closing means”. The specific area switch 76 corresponds to “specific area detecting means”. The CPU 51 that generates the “probability variation short state” in S128 and S129 of FIG. 14 functions as the “first advantageous state generating means”.

  The present invention is not limited to the embodiment described in detail above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. First, in the said embodiment, the time short state when the ratio by which the 2nd special symbol starting electrically-driven accessory 15 is opened becomes higher than usual is employ | adopted. However, it is possible to realize the present invention without adopting the time reduction state. For example, the present invention can be realized even if a normal winning opening without an opening / closing member is arranged in place of the second special symbol starting electric accessory 15 and the normal symbol starting gate 12 is omitted. Even in this case, according to the present invention, the rate at which the probability variation state occurs can be easily made different between the two jackpot determinations.

  In the second special symbol start electric accessory 15 of the above embodiment, a game ball can be won only when the opening / closing member is opened. However, you may use the electric combination which can win a game ball while the opening-and-closing member is open | released as the 2nd special symbol starting electric combination 15. Even in this case, it is easy to win a game ball to the second special symbol starting electric accessory 15 during the time-shortening state, so that the flow of the game is the same as in the above embodiment.

  In the above embodiment, when it is determined that the probability variation jackpot is determined in the second jackpot determination, the ratio of the long-time opening jackpot is 100%. However, this value may be less than 100%. That is, when it is determined that the probability variation jackpot, the probability of a long-term open jackpot may be different between the two jackpot determinations, and specific numerical values may be set as appropriate.

  In the above-described embodiment, three game states, “normal state (non-probability variation non-short state)”, “probability variation short state”, and “non-probability variation short state” occur. The pachinko machine 1 according to the above embodiment can change the ratio of occurrence of the “probability variation short-time state” between the two jackpot determinations without causing the “probability variation non-short-time state”. Can be prevented from becoming complicated. However, it goes without saying that the present invention can also be applied to a gaming machine that causes a “probability variation non-short-time state”.

  In the above embodiment, three types of jackpot types are adopted: “probability variation long-time open jackpot”, “probability variation short-time open jackpot”, and “non-probability variation short-time open jackpot”. However, different jackpot types may be adopted. For example, “non-stochastic fluctuation long open big hit” may be adopted. In this case, it is easy to pass the game ball into the specific area 18 in the V attacker 17, but even if the game ball passes through the specific area 18, the probability variation state does not occur. Therefore, it is not possible to determine whether or not a probability variation state is subsequently caused only by looking at the game result during the jackpot game (whether or not the game ball has passed through the specific area 18). Therefore, the player's expectation for the occurrence of the probability variation state can be maintained for a longer time.

  In the above embodiment, when reporting the results of the first jackpot determination in the “short state at the time of probability change” and the “short state at the time of non-probability change”, the average of the notification time is set to be longer than that in the “normal state” Has been. This increases the frequency with which the second jackpot determination is performed during the short-time state, thereby reducing the possibility of so-called “puncture”. Here, in the above embodiment, the average of the notification time is varied by changing the variation time in the case of “non-reach” according to the gaming state (see FIG. 7). However, the method of adjusting the average of the notification time is not limited to the method of adjusting the variation time in the case of “non-reach”. For example, you may increase the average of alerting | reporting time by increasing the selection probability of the fluctuation pattern which performs reach production. The average of the notification time may be increased by increasing the fluctuation time of the fluctuation pattern other than “non-reach”. Moreover, in order to increase the frequency with which the second jackpot determination is performed during the short-time state, it is desirable to execute the second jackpot determination with priority over the first jackpot determination. However, the present invention can be realized even if the jackpot determination is executed in order from the special symbol actuated holding ball that is won early.

  In the above embodiment, when the game ball does not pass the specific area 18 during the jackpot game, the “non-probability short time state” occurs after the jackpot game ends. Since the second jackpot determination is frequently performed during the “non-probability short time state”, it is possible to increase the player's expectation for the transition to the “probability short time state”. However, when the game ball does not pass through the specific region 18, it is possible to shift to the “normal state” without causing the “non-probability short time state”. In other words, the present invention can also be applied to a gaming machine that causes only two game states of “normal state” and “probability variation short state”. In addition, the “non-stochastic variation short time state” may occur only after either the jackpot in the non-stochastic fluctuation state or the jackpot in the probability fluctuation state.

  In the above embodiment, two opening patterns, a long-time opening pattern and a short-time opening pattern, are provided as the opening pattern of the V attacker 17. However, the opening pattern of the V attacker 17 is not limited to two. For example, one or a plurality of chance opening patterns for releasing the V attacker 17 for a time shorter than the opening time in the long-time opening pattern and longer than the opening time in the short-time opening pattern may be provided. In the chance release pattern, the longer the opening time of the V attacker 17 is, the more likely the “probability variation short state” is to occur thereafter. When the chance release pattern is selected, the player can enjoy the jackpot game with a strong expectation that the game ball will pass through the specific area 18.

  In the above embodiment, when the short-time release pattern is selected, the release time of the V attacker 17 is 0.3 seconds shorter than the game ball firing interval. By slightly opening the V-attacker 17, the number of rounds of the jackpot game in the case of long-time open big hit and the number of rounds in the case of short-time open big hit are made the same, and the type of jackpot game is determined by the number of rounds This can be prevented. However, the opening time of the V attacker 17 when the short-time opening pattern is selected may be “0 seconds” (that is, not opened).

  The round for releasing the V attacker 17 does not have to be the final round in one jackpot game. Further, in one big hit game, the V attacker 17 may be released in a plurality of rounds. In this case, by changing the total opening time of the V attacker 17 in one jackpot game between the long-time opening pattern and the short-time opening pattern, the rate of transition to the “short state at the time of probability change” can be changed.
