Description

  The present invention relates to a gaming machine that determines a gaming state that shifts after the end of a jackpot game, depending on whether or not a game ball that has won a prize opening passes a specific area.

  2. Description of the Related Art Conventionally, a gaming machine having a specific area through which only a game ball that has won a prize opening can pass is known. For example, the gaming machine described in Patent Document 1 includes a variable winning device at the center of the gaming board. The variable winning device includes an electric combination, a rotating body, and a sorting member. The electric accessory is released when a specific condition is established. The game ball can enter the winning opening of the variable winning device only when the electric accessory is opened. The rotating body includes a specific area and a non-specific area. The distribution member distributes the game balls won from the winning opening to either the specific area or the non-specific area. When the game ball passes through the specific area, a probability variation state in which the probability of being determined to be a big hit is higher than usual is generated after the end of the big hit game.

JP 2009-5901 A

  In a conventional general gaming machine, whether or not to shift the gaming state to the probability variation state is determined depending on whether or not the probability variation jackpot that is a jackpot for shifting to the probability variation state. That is, in the conventional gaming machine, the rate of shifting to the probability variation state is the same as the rate of winning the probability variation. Therefore, when the ratio of transition to the probability variation state is changed between a plurality of jackpot determinations, the ratio of the probability variation jackpot is restricted. Here, providing a difference in the proportion of probability variation jackpots among a plurality of jackpot determinations leads to a lack of game fairness. Therefore, in the conventional gaming machine, it is difficult to change the rate of transition to the probability variation state between a plurality of jackpot determinations.

  Therefore, it is conceivable to apply the technique disclosed in Patent Document 1 to a conventional gaming machine to change the rate of transition to the probability variation state. Specifically, a variable winning opening provided with a specific area and a non-specific area is provided, and a game ball that has won a prize in the variable winning opening passes through the specific area as a condition for shifting to the probability variation state. In this case, the longer the opening time of the variable winning opening is, the easier the game ball passes through the specific area, and thus the rate of transition to the probability variation state increases. And the ratio which transfers to a probability variation state can be changed between several jackpot determination by providing a difference in the opening time of a variable winning opening between several jackpot determinations.

  However, in addition to winning a lottery to determine whether or not to win the probability variation, if the game ball passes through a specific area as a condition for transition to the probability variation state, it must pass through a two-stage lottery, The game becomes complicated. Therefore, it has been difficult for a conventional gaming machine to change the rate of transition to the probability variation state between a plurality of jackpot determinations without complicating the game.

  An object of this invention is to provide the gaming machine which can change the ratio which transfers to a probability fluctuation state between several jackpot determination, without making a game complicated.

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 detection of a game ball, first jackpot determination means for determining whether or not to execute a jackpot game that is advantageous to the player, a passage opening provided on the game board, and the passage opening A passage opening detecting means for detecting a game ball that has passed through, and a normal state for determining whether or not to execute a normal hit game advantageous to the player due to the detection of the game ball by the passage opening detecting means A second start port having a hit judging means and an opening / closing member, and allowing the game ball to be won or facilitated by opening the opening / closing member; and an opening / closing member of the second start port during the normal hit game Second opening and closing means for opening and closing 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 winning jackpot by the first jackpot determining means, and a special winning opening that has an opening / closing member and that allows a game ball to be won only when the opening / closing member is opened. The opening pattern of the opening / closing member of the special prize opening is a long-time opening pattern in which a game ball can easily pass through the specific area, and the opening time is shorter than the opening time by the long-time opening pattern. The first determination means for determining one of the short-time release patterns in which the passing of the game ball to the specific area is more difficult than the long-time release pattern, and the second big hit determination means is determined to be a big hit. A second determining means for determining an opening pattern of the opening / closing member of the special prize opening as one of the long-time opening pattern and the short-time opening pattern; and the first jackpot determining means or the second jackpot An informing means for informing the player of the determination result of the determining means, and an opening determined by the first determining means or the second determining means during the jackpot game executed after the jackpot is notified by the notifying means. Special prize opening opening / closing means for opening and closing the opening / closing member of the special prize opening according to a pattern, and specific area detection means for detecting a game ball that has passed through a specific area through which only a game ball won in the special prize opening can pass And the first jackpot determination means and only on the condition that a game ball is detected by the specific area detection means during the jackpot game Probability fluctuation occurrence means that occurs after the end of the jackpot game, a probability fluctuation state in which the probability that the second jackpot determination means is determined to be a big hit is higher than a normal probability, and at least the jackpot game is executed As a condition, when the rate at which the opening / closing member of the second start port is opened is higher than usual, the short-time occurrence means that occurs after the end of the jackpot game, the first jackpot determination means, and the second jackpot Counting means for counting the number of times that the judgment means has determined to be consecutively discontinued, and end means for terminating the probability variation state and the time-shortening state when the number of times counted by the counting means reaches a predetermined number of times. The probability that the second determining means determines the long-time release pattern is the probability that the first determination means determines the long-time release pattern. Higher than the probability that a constant, and Ri less than 100% der, the predetermined number of times the termination unit is a reference to terminate the probability change state and the time-shortening conditions, characterized in der Rukoto least 8500 times.

  According to the gaming machine according to the present invention, a special prize is awarded when a game ball is won at the first start opening and determined as a big win, and when a game ball is won at the second start opening and determined as a big win. The rate at which the mouth is opened for a long time is different. When the special prize opening is opened for a short time, it is difficult for the game ball to pass through the specific area, and the probability variation state is unlikely to occur. If the special prize opening is opened for a long time, it is easy for the game ball to pass through the specific area, and therefore a probability variation state is likely to occur. If a short-term probability change state occurs after the jackpot game ends, the frequency of the jackpot determination (second jackpot determination) by the second jackpot determination means will increase compared to the normal state (non-probability variation non-short-time state). In addition, the probability of being determined to be a big hit also increases. If it is determined that the second jackpot is determined to be a jackpot, the special winning opening is opened for a long time at a higher rate than in the normal state, so that the probability fluctuation short time state is likely to occur again thereafter. In other words, the probability that the probability change short state continues through the jackpot game is higher than the probability that the normal state shifts to the probability change short state via the jackpot game. Therefore, the gaming machine according to the present invention has a probability between the case where it is determined that the jackpot is determined by the first jackpot determination means (first jackpot determination) and the case where it is determined that the jackpot is determined by the second jackpot determination. The rate of transition to the short state at the time of change can be changed.

  Furthermore, in the gaming machine according to the present invention, whether or not to generate the probability variation state is determined only by whether or not the game ball passes through the specific area. Whether or not the probability variation jackpot is a condition for causing a probability variation state. Accordingly, the ratio of transition to the probability variation state can be changed between the two jackpot determinations without the game being complicated by the two-stage conditions. Note that, in the gaming machine according to the present invention, in order to make the condition that the probability variation state occurs only when the game ball passes through the specific area, the ratio of the probability variation big hit is 100%. When the ratio of the probability variation jackpot is set to 100%, the probability variation state is not allowed to continue until it is determined to be the next jackpot because the probability variation state continues unreasonably. The gaming machine according to the present invention is provided with a function (so-called “ST function”) that terminates the probability variation state when it is determined to be out of sequence for a predetermined number of times, so that the probability of winning the probability variation is 100%. The occurrence condition of the probability variation state can be made one. In addition, by providing a configuration in which the ST function is provided so that the short-term opening pattern can be selected even in the second jackpot determination, the opening pattern of the special winning opening at the time of the second jackpot determination (that is, whether or not the probability variation state continues) Can attract the attention of the player.

Also, even if the game of the day ends without being determined to be a big hit during the probability variation short-time state , if the predetermined number of times (so-called “ST number”) is 8500 times or more, the probability variation short-time state ends. There is nothing. Accordingly, in this case, although the gaming machine is provided with the ST function, the gaming machine is a gaming machine (so-called “loop type” gaming machine) in which the probability variation short-time state continues until the next big hit. That is, according to the present invention, it is possible to realize a loop-type gaming machine in which the transition rate to the probability variation time shortening is different between the first jackpot determination and the second jackpot determination without complicating the game.

  The time-shortening generating means may cause the time-shortening condition on condition that the jackpot game is executed and the long-time release pattern is determined by the first determining means or the second determining means. . In this case, after the special winning opening is opened for a short time, a non-time-saving state is generated regardless of whether or not the game ball passes through the specific area. In the non-time-short state, since the frequency of the first jackpot determination is high, it is difficult to shift to the probability variation state. Therefore, when the special prize opening is opened for a short time, even if the game ball passes through the specific area due to cheating and irregularity, a time saving state advantageous to the player is not generated. Therefore, it is possible to suppress the occurrence of fraud and irregular effects while attracting the player's interest sufficiently using the specific area. In addition, when the special prize opening is opened for a long time, even if the game ball does not pass through the specific area, the time-short state is generated. Therefore, the game can be continued while suppressing the discouragement of the player.

  The average of the notification time when the notification means notifies the determination result of the first jackpot determination is longer in the case where the short-time state has occurred than in the case where the short-time state has not occurred. Also good. In this case, if the short-time state has occurred, it becomes easier to win the game ball at the second start port while the determination result of the first jackpot determination is informed. As a result, it is possible to reduce the possibility that the continuation of the time-saving state is interrupted because it is determined as the first big hit during the time-saving state.

  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 jackpot is determined during the time-short state and the continuation of the time-short state is interrupted.

  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 front 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 front 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. In the center of the rendering device 30, a display screen 28 that is an LCD is disposed. 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 second special symbol starting electric accessory 15 may be an electric accessory that allows a game ball to win even when the opening and closing member is closed. In this case, when the opening / closing member is in the open state, it is easier to win a game ball to the electric accessory than in the closed state. 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.

  Although the details will be described later, in the pachinko machine 1, only the game ball passes through the specific area 18 in the V-attacker 17 during the jackpot game is a condition for causing the probability variation 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 FIG. 1 and FIG. 2, a symbol display unit 8 is provided on the lower right side of the game area 4. The symbol display unit 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.

  When the game ball passes through the normal symbol start gate 12, the normal hit determination is performed, and the determination result is displayed on the normal symbol display unit 24. 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 a “non-probability variation non-short state” (hereinafter referred to as “normal state”), “non-probability variation short state”, “probability variation non-short state”, and “probability variation”. Four game states of “short time state” occur.

  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”. . The “probability variation non-short-time state” and “probability variation short-time state” are terminated when the sum of the number of first jackpot determinations and the number of second jackpot determinations reaches a specified number (10,000 in this embodiment), Transition to “normal state”. That is, the probability variation state of the pachinko machine 1 is terminated by the operation of a so-called number cut probability changing function (ST) when the sum of the number of jackpot determinations reaches a specified number. The “non-probability change short state”, “probability change non-short state”, and “probability change short state” are also terminated at the start of the jackpot game. In this case, the specified number of counts is cleared. The specified number of times can be changed as appropriate. For example, a jackpot with a prescribed number of 50 times to end the “non-probability short time state” and a jackpot with 100 times may be provided. In addition, when the “probability variation short state” has occurred, the specified number of times for ending the short time state and the specified number of times for ending the probability variation state may be set separately.

  During the “normal state” and the “probability variation non-short-time state” (that is, during the non-time-short state), the ratio of the opening / closing member of the second special symbol starting electric accessory 15 being opened is lower than that in the short-time 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 first big hit is a big hit, it is determined whether to generate a long-time open big hit or a short-time open big hit. In the present embodiment, when it is determined that the jackpot is determined by the first jackpot determination, the ratio at which the long-time opening jackpot is determined is 50%, and the ratio at which the short-time opening jackpot is determined is also 50%. In addition, you may change the ratio by which long-time opening jackpot is determined. As described above, in the case of a big hit for a long time, the game ball passes through the specific area 18 in the V attacker 17 with a very high probability. On the other hand, in the case of a big hit for a short time, the probability that the game ball passes through the specific area 18 is very low.

  In the pachinko machine 1, when a game ball passes through the specific area 18 during a jackpot game, a probability variation state is generated after the jackpot game ends. Specifically, when the game is a big hit for a long time and the game ball passes through the specific area 18, the game state shifts to a “probability change short state”. If the long-open jackpot is digested as usual, the probability that the game ball passes through the specific area 18 is almost 100%. Therefore, the probability of shifting from the “normal state” through the jackpot game to the “probability variation short state” is about 50%.

  During the “short state at the time of probability change” and the “short state at the time of non-probability change” (that is, during the time short state), the rate at which the opening / closing member of the second special symbol starter electric accessory 15 is opened is from the “normal state”. Is also expensive. 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 at which the long-time opening jackpot is determined is 80%, and the ratio at which the short-time opening jackpot is determined is 20%. Here, the ratio at which the long-time open jackpot is determined at the time of determining the second jackpot is higher than the ratio at which the long-time open jackpot is determined at the time of determining the first jackpot, and may be less than 100%. For example, the ratio can be set as appropriate. In the pachinko machine 1, the probability that the “probability variation short state” continues through the jackpot game is higher than the probability of transition from the non-short state to the “probability variation short state”.

  Here, in the conventional general gaming machine, unlike the pachinko machine 1 of the present embodiment, whether or not to shift to the probability variation state depending on whether or not the probability variation jackpot is a jackpot to shift to the probability variation state. Is decided. Therefore, in the conventional gaming machine, the rate of shifting to the probability variation state is the same as the rate of winning the probability variation. Therefore, when the ratio of transition to the probability variation state is changed between a plurality of jackpot determinations, the ratio of the probability variation jackpot is restricted. And, providing a difference between a plurality of jackpot determinations in the ratio of probability variation jackpots leads to a lack of game fairness, and is actually prohibited by rules. Therefore, in the conventional gaming machine, it has been difficult to change the ratio of shifting to the probability variation state between a plurality of jackpot determinations. On the other hand, as in the pachinko machine 1 of the present embodiment, if the control is performed so that the V attacker 17 is easily opened for a long time at the time of the second jackpot determination rather than at the time of the first jackpot determination, the state shifts to the probability fluctuation state. Differences can be made in the proportions.

  However, in addition to winning the lottery to determine whether or not to win the probability variation, if the game ball passes through the specific area 18 as a condition for shifting to the probability variation state, a two-stage lottery must be passed. , The game becomes complicated. Such specifications are also prohibited by the rules. Therefore, in order to avoid the two-stage lottery, it is possible to simply set the ratio of the probability variation jackpot to 100%. However, without providing a function to limit the number of consecutive successes of the probability fluctuation jackpot (so-called “limiter function”), the probability fluctuation jackpot ratio is set to 100%, and the probability fluctuation state is continued until the next jackpot is determined. Since the probability variation state continues unreasonably (that is, the ST function is not provided), this is also actually prohibited by the rules. The pachinko machine 1 of the present embodiment can solve the various problems described above. That is, without complicating the game and preventing the probability variation state from continuing unfairly, the ratio of transition to the probability variation state is determined by a plurality of jackpot determinations (first jackpot determination and second jackpot determination). It can be changed between. Hereinafter, the details of the processing and the like executed by the pachinko machine 1 will be described.

  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.

  A normal symbol operation switch 74, a normal attacker switch 75, a specific area switch 76, and a non-specific area switch 77 are connected to the relay board 47. The normal symbol operation switch 74 detects a game ball that has passed through the normal symbol start gate 12. The normal attacker switch 75 detects a game ball that has won the normal attacker 16. The specific area switch 76 detects a game ball that has passed through the specific area 18 in the V attacker 17. The non-specific area switch 77 detects a game ball that has passed through the non-specific area 19 in the V attacker 17. Further, the relay board 47 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 display unit 60. The symbol memory number display LED 61 is connected.

  The power supply board 42 is connected to the main board 41 and the game ball launching device 37, and supplies DC stabilized power to each board and the game ball launching device 37. The game ball launching device 37 launches one game ball to the game area 4 at regular intervals (0.6 seconds in the present embodiment).

  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. .

  A 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. The jackpot special symbol is classified into either a long-open big jackpot or a short-open big jackpot. As described above, in the case of a long open big hit, the V attacker 17 is released for a maximum of 13 seconds, so that it is easy to win a game ball in the specific area 18 in the V attacker 17. Therefore, it shifts to the probability fluctuation state with a very high probability thereafter. In the case of a short-open big hit, since the V attacker 17 is released only for a maximum of 0.3 seconds, it is difficult to win a game ball in the specific area 18. Therefore, the probability of subsequently shifting to the probability variation state is very low.

  In the pachinko machine 1, when it is determined that the first jackpot is a jackpot, the ratio of the long-time opening jackpot is 50%, and the ratio of the short-time opening jackpot is also 50%. On the other hand, when it is determined that the big jackpot is determined in the second jackpot determination, the ratio of the long-time opening jackpot is 80%, and the ratio of the short-time opening jackpot is 20%. In other words, the percentage of long-term open jackpots is higher when the jackpot is determined by the second jackpot determination than when the jackpot is determined by the first jackpot determination. However, even if it is determined that the second jackpot is determined to be a jackpot, there may be a case where the jackpot is a short-time open jackpot. Therefore, the player pays attention to the contents of the game, expecting that if the player wins the jackpot during the short-time state, the probability variation state is caused by the jackpot for a long time, not the jackpot for a short time.

  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. 6) and a second special symbol variation pattern determination table (see FIG. 7). 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. 6 and 7, 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. 6, the variation time of “non-reach” during the non-time-short state in the first jackpot determination (that is, “normal state” and “probability variation non-time-short state”) 10 seconds, 8 seconds when the number of reserved balls is “1 or 2”, and 6 seconds when the number of held balls is “3-8”. On the other hand, the variation time of “non-reach” during the short-time state (that is, “non-probability short-time state” and “probability short-time state”) is 11 seconds when the number of held balls is “0”, and the number of held balls Is 9 seconds when “1 or 2” is “7 or 2” and 7 seconds when the number of reserved balls is “3 to 8”. That is, the average of the variation time of “non-reach” during the time reduction state is 1 second longer than the average of the variation time of “non-reach” during the non-time reduction state. Therefore, during the short-time state, the fluctuation time for notifying the result of the first jackpot determination becomes long, and it becomes easy for the second special symbol start electric accessory 15 to win a game ball during this notification time. .

  Further, as shown in FIG. 7, the fluctuation time of “non-reach” during the short time state in the second jackpot determination is 10 seconds when the number of held balls is “0”, and when the number of held balls is “1 or 2”. It is 3 seconds when the number of reserved balls is “3-8” for 4 seconds. That is, the average fluctuation time of “non-reach” during the short-time state is shorter in the case of informing the result of the second jackpot determination than in the case of informing the result of the first jackpot determination. Therefore, during the short-time state, the result of the second jackpot determination is notified in a short time, and it takes a long time to notify the result of the first jackpot determination. As a result, the possibility that the first jackpot determination is performed during the short-time state decreases.

  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 (see FIG. 8) is executed by the CPU 51 when the CPU 51 senses an interrupt signal generated every 4 ms by the interrupt signal generation circuit 57 (see FIG. 4).

  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 the game state that occurs after the jackpot game ends are performed (see FIGS. 12 and 13).

  Next, special symbol processing is performed (S14). In the special symbol processing, jackpot determination, determination of special symbols, gaming state transition processing, and the like are performed (see FIGS. 9 to 11).

  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 RAM 52 stores a jackpot gaming state flag, a 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 display status flag is “1” when either one of the two special symbol display portions 25 and 26 is changing (during change), and “one” is displayed when either one 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 winning of a game ball, a flag corresponding to the first start switch 72 in the switch reading process of the main process (see S11, FIG. 8). 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 number of first special symbol operation reservation balls 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 number of first special symbol operation reservation balls (S23). Next, various random numbers are acquired and stored in the RAM 52 (S24). Specifically, the value of the first jackpot determination counter (first jackpot determination random number), the value of the first special symbol determination counter (first special symbol determination random number), and the value of the first variation pattern determination counter (first Fluctuation pattern determining random numbers) are stored in the RAM 52, respectively.

  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 proceeds to determination of S31 as it is. If a game ball has won the second special symbol start electric accessory 15 (S25: YES), it is determined whether or not the number of second special symbol actuated balls 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). The value of the second jackpot determination counter (second jackpot determination random number), the value of the second special symbol determination counter (second special symbol determination random number), and the value of the second variation pattern determination counter (second variation pattern determination random number) Are acquired and stored in the RAM 52 (S28).

  Next, 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. 10), 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. 10, first, it is determined whether or not the number of second special symbol actuating 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 holding balls is “1” or more (S35: YES), the first special symbol operation holding balls is subtracted from “1” (S36), and the first jackpot determination is performed (S37). ). The first jackpot determination is performed in the order in which they are stored by referring to a determination table corresponding to whether or not the probability variation state is in effect, and using an undetermined first jackpot determination random number stored in the RAM 52. Next, the variation pattern is determined by the table according to the gaming state and the determination result in the first special symbol variation pattern determination table (see FIG. 6). 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 first variation pattern determination random number (S39). Next, according to the special symbol determination table (see FIG. 5), one of the first special symbols indicating the first jackpot is determined by the first jackpot special symbol determination random number (S40). As described above, in the case of the first jackpot determination, the ratio of the long-time open jackpot is 50%. The process proceeds to S51. 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 S51. 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 number of second special symbol actuated balls (S43), and a second jackpot determination is made according to whether or not the probability variation state is being performed (S44). If it is a big jackpot (S45: YES), a variation pattern indicating that it is a second jackpot is determined (S46), and a second special symbol indicating that it is a second jackpot is determined (S47). The process proceeds to S51. In the case of the second jackpot determination, the percentage of long-time open jackpot is 80%. 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 S51.

  When the big hit determination is completed, a variation pattern designation command for designating the determined variation pattern is stored in the RAM 52 (S51). The variation pattern designation command is transmitted to the sub control board 58 in the command output process (S10, see FIG. 8) of the main process to be executed next time. 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 display state flag (S53), and the process returns to the main process.

  Further, in the determination of S32 shown in FIG. 9, when “1” is stored in the 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. 10) 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 units 25 and 26 is in a stop display is stored in the 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 display state flag and one of the special symbol display units 25 and 26 is being stopped (S33: YES), S56 is displayed. Whether or not the stop display time has elapsed is determined based on the counter value set in (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 the special symbol display portions 25 and 26 are neither changing nor being stopped is stored in the display state flag (S60). Next, a first game state transition process is performed (S61), and the process returns to the main process.

  With reference to FIG. 11, the first gaming state transition process will be described in detail. In the first game state transition process, a flag control for shifting to a jackpot game and a flag control for ending the short-time state and the probability variation state are performed when it is determined that the jackpot is a big hit. First, it is determined whether or not the jackpot determination result is a jackpot (S63). If it is not a jackpot (S63: NO), “1” is set to the value of the jackpot determination count counter that counts the number of jackpot determinations made after the end of the previous jackpot game (the number of times it was determined that the game was consecutively lost) It is added (S64). Note that the process of S64 may not be executed during the “normal state”.

  Next, whether or not the gaming state is the “non-probability short time state” is determined by the probability variation flag and the short time flag (S65). During the “non-probability change short state”, the probability change flag is set to “OFF” and the time reduction flag is set to “ON”. If it is “short state at the time of non-probability change” (S65: YES), whether or not the number of determinations reaches 100 is determined by the value of the jackpot determination number counter (S66). If it has not reached 100 times (S66: NO), the process returns to the special symbol process (see FIG. 9) as it is. When it reaches 100 times (S66: YES), the time reduction flag is set to “OFF” (S67), the gaming state is shifted to the “normal state”, and the process returns to the special symbol process.

  If the gaming state is not “non-probability variation short state” (S65: NO), whether or not the probability variation state has occurred (that is, the gaming state is “probability variation short state” or “probability variation non-short state”). Is determined) (S69). If the probability variation state has not occurred and the game state is “normal state” (S69: NO), the process returns to the special symbol process as it is. If the probability variation flag is set to “ON” and a probability variation state has occurred (S69: YES), whether or not the number of determinations has reached 10000 is determined by the value of the jackpot determination number counter. (S70). If it has not reached 10,000 times (S70: NO), the process returns to the special symbol process as it is. If it has reached 10,000 times (S70: YES), the probability variation flag is set to “OFF”, and if the time reduction flag is set to “ON”, it is changed to “OFF” (S71). That is, the “probability variation short state” or the “probability variation non-short state” is shifted to the “normal state”. The process returns to the special symbol process.

  If the result of the jackpot determination is a jackpot (S63: YES), the value of the jackpot determination count counter is initialized (S73). “1” indicating that the jackpot game is being played is stored in the jackpot game state flag and set to “ON” (S74). If the probability variation flag and the time reduction flag are set to “ON”, it is changed to “OFF” (S75), and the process returns to the special symbol process.

  With reference to FIG. 12, the details of the special electric accessory process (S13, see FIG. 8) 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. 12, 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 (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. 8). 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). Next, a second game state transition process is performed (S125), and the process returns to the main process.

  The second gaming state transition process will be described with reference to FIG. In the second game state transition process, the game state is controlled at the end of the jackpot game. First, in order to end the jackpot game, the jackpot game state flag is set to “OFF” (S131). It is determined whether or not the game ball has passed through the specific area 18 in the V attacker 17 during the big hit game (S132). When the specific area switch 76 (see FIG. 4) detects a game ball that has passed through the specific area 18, the flag corresponding to the specific area switch 76 is set to “ON” in the switch reading process (S11, see FIG. 8) of the main process. Is done. If this flag is set to “ON” (S132: YES), the probability variation flag is set to “ON” (S133), and the process proceeds to the determination of S134. If the game ball has not passed through the specific area 18 (S132: NO), the process proceeds to the determination of S134 while the probability variation flag remains “OFF”.

  Next, it is determined whether or not the type of jackpot game has been a jackpot for a long time (S134). If it is a big hit for a long time (S134: YES), the time reduction flag is set to "ON" to cause a time reduction state (S135), and the processing returns to the special electric accessory processing. If it is a short-open big hit (S134: NO), the process returns to the special electric accessory process while the hourly flag remains “OFF”.

  With reference to FIG. 14, the game executed in the pachinko machine 1 will be described. In the pachinko machine 1, the gaming state with the highest occurrence rate is the “normal state (non-probability variation non-short-time state)”. In the “normal state” and the “probability variation non-short-time state” (that is, the non-time-short state), the rate at which the opening / closing member of the second special symbol starter 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 non-time-saving state is almost the first jackpot determination.

  When it is determined that the jackpot is determined by the first jackpot determination, the ratio of the long-time opening jackpot is 50%, and the ratio of the short-time opening jackpot is also 50%. When the jackpot is opened for a long time, the opening time of the V-attacker 17 during the jackpot game becomes longer, and the game ball passes through the specific area 18 in the V-attacker 17 with a high probability. When the big hit is a big hit for a long time and the game ball passes through the specific area 18, the gaming state after the big hit game is ended becomes a “short state at the time of probability change”.

  In the present embodiment, the player fires a game ball to the right part of the game board 2 during the jackpot game (so-called “right strike”). A normal symbol start gate 12 and a second special symbol start electric accessory 15 are 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. During the non-short-time state, at least one of the probability determined to be a normal hit, the variation time of the normal symbol, and the opening time of the second special symbol starting electric accessory 15 is made different from that during the short-time state, The rate at which the symbol starting electric accessory 15 is opened is set lower than in the time-short state. However, in the present embodiment, the probability that the game is determined to be a normal hit and the fluctuation time 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. The opening time of the second special symbol start electric accessory 15 is set. Therefore, during the jackpot game, the number of second special symbol actuated holding balls increases on average.

  In the “short state at the time of probability change” and the “short state at the time of non-probability change” (that is, the short time 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. Furthermore, during the time reduction state, the effect time of the notification effect indicating the result of the first jackpot determination (the symbol variation time of the first special symbol display unit 25) is longer than that in the non-time reduction state (see FIG. 6). . As a result, it is easier for the second special symbol start electric accessory 15 to win a game ball during the change of the first special symbol than in the non-short-time state. From the above, the jackpot determination executed during the 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 jackpot is opened for a long time at a higher rate (80%) than when the jackpot is determined by the first jackpot determination. That is, the probability that the “probability variation short state” solves the jackpot game and continues is higher than the probability of transition from the “normal state” to the “probability variation short state” via the jackpot game. Accordingly, the pachinko machine 1 changes the rate of transition to the “probability short time state” between the case where the first jackpot determination is determined to be a jackpot and the case where the second jackpot determination is determined to be a jackpot. Can do.

  More specifically, the conventional general gaming machine determines the subsequent gaming state using only the determination result as to whether or not the jackpot type is a probability variation jackpot. And it is not performed to change the ratio of the probability variation jackpot between the two types of jackpot determination because the game is complicated and prohibited by the rules. Therefore, in the conventional gaming machine, the game contents cannot be sufficiently diversified. However, the pachinko machine 1 according to the present embodiment can sufficiently diversify the game contents by changing the proportion of the game balls passing through the specific area 18 between the two types of jackpot determination.

  Here, in the pachinko machine 1, whether or not to generate the probability variation state is determined only by whether or not the game ball passes through the specific area 18. Whether or not to become a probability variation jackpot is not a condition for causing a probability variation state, so the probability of being a probability variation jackpot is 100%. Therefore, unlike the case of providing two-stage conditions (passing through the specific area 18 and probability variation jackpot), the game is not complicated. If the probability variation jackpot is set to 100% and the probability variation state is continued until the next jackpot is determined, there is a risk that the probability variation state will continue unreasonably and lack game stability. is there. The pachinko machine 1 according to the present embodiment includes a function (so-called “ST function”) that terminates the probability variation state when it is determined that a predetermined number of consecutive deviations occur, so that the probability of the probability variation jackpot is 100%. However, the occurrence condition of the probability variation state can be reduced to one. In addition, by providing a configuration in which an opening pattern can be selected for a short time even in the second jackpot determination while having the ST function, the opening pattern of the V attacker 17 at the time of the second jackpot determination (that is, the probability fluctuation state is substantially Whether or not to continue) can attract the player's attention.

  Further, in the present embodiment, the number of consecutive failures (so-called “ST number”) for ending the “probability variation short state” by operating the ST function is set to a very large value of 10,000 times. . The probability of being determined to be a big hit in the probability variation state is about 1/35, and a value more than 250 times this denominator is set as the ST number, and the ST function may be activated 10,000 times consecutively. Is infinitely close to 0%. Furthermore, in the pachinko machine that causes the short-time state as in the present embodiment, the number of times that the jackpot determination is performed during the short-time state is, on average, 12 times per minute. Therefore, even if it is assumed that the game in the short state with the probability variation is continued for 12 hours, the number of jackpot determinations is “about 12 × 60 minutes × 12 hours = about 8640 times”. And considering that it is difficult to continue the game for 12 hours, it can be said that the number of jackpot determinations that can be executed in a day does not exceed 8500 times. The pachinko machine 1 is a gaming machine (so-called “loop type” gaming machine) in which the “probability variation short state” continues until the next big hit by setting the ST number to 8500 times or more. . In other words, the pachinko machine 1 realizes a loop-type gameability in which the transition rate to the “probability change short state” is different between the first jackpot determination and the second jackpot determination without complicating the game content. It is. This feature is a remarkable feature that has never been seen in conventional gaming machines.

  In the pachinko machine 1, after the V-attacker 17 is released for a short time, a non-time-short state, not a time-short state, occurs regardless of whether or not the game ball has passed through the specific area 18. In the non-time-short state, since the frequency of the first jackpot determination is high, the gaming state is less likely to shift to the “probability variation time-short state” as compared to the time-short state. That is, when the V attacker 17 is released for a short time, even if the game ball passes through the specific area 18 due to cheating and irregularities, a gaming state (short state when probability change is short) that is most advantageous to the player is generated. There is nothing to do. Therefore, the pachinko machine 1 can suppress the occurrence of fraud and irregular effects while sufficiently attracting the player's interest using the specific area 18.

  In addition, even if the game is a big hit for a long time, there is very little possibility that the game ball will not pass through the specific area 18 due to irregular effects. In the pachinko machine 1, if the game ball does not pass through the specific area 18 in the case of a big hit for a long time, the probability variation state is not generated, but the short-time state is generated. 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 second jackpot is determined to be a jackpot, since it will be a long-term open jackpot at a higher rate than if the first jackpot determination is determined to be a jackpot, then the “probability change short state” Easy to occur. 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”. Yes, the expectation will not be greatly diminished. That is, it is possible to suppress the disappointment of the player when the game ball does not pass through the specific area 18 in the big hit for a long time.

  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 probability that the short-time state will be interrupted will increase from 20% (in the case of the second jackpot determination) to 50% (this will cause the time-short state to be continuous) Is referred to as “punk” below). Therefore, in order to reduce the possibility of disappointment of the player due to “puncture”, it is necessary to reduce the frequency with 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. Moreover, the time of the notification effect of the first jackpot determination in the time reduction state is made longer than that in the non-time reduction 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”. As a result, the frequency at which the player is discouraged by “punk” decreases.

  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. In the above-described embodiment, when the long-time release pattern is selected and the game ball does not pass through the specific area 18, the “non-probability short time state” is generated after the jackpot game ends. Since the second jackpot determination is frequently executed during the “non-probability short time state”, the disappointment of the player when the game ball does not pass through the specific area 18 can be suppressed. However, when the long-time release pattern is selected and the game ball does not pass through the specific area 18, it is possible to shift to the “normal state” without causing the “non-probability short state”.

  In the said embodiment, when alerting | reporting the result of the 1st jackpot determination in a time-short state, it sets so that the average of alerting | reporting time may become longer than in a non-time-short state. 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 said embodiment, the average of alerting | reporting time is varied by varying the fluctuation | variation time in the case of "non-reach" according to a gaming state (refer FIG. 6). 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 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-saving state, so that the game flow is the same as in the above embodiment.

  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, it is possible to change the rate of transition to the “short state at the time of probability change”. .

  In the above-described embodiment, when the short-time release pattern is selected, the time-short state does not occur after the jackpot game ends. This suppresses the occurrence of fraud and irregular effects. However, it is also possible to cause a time-short state after the end of the short-time opening jackpot. In this case, for example, the game content may be diversified by setting the number of time reductions after the short time opening jackpot ends to a number less than the number of time savings after the long time opening jackpot ends.

  In the above-described embodiment, the loop function gaming machine is substantially set by setting the continuous number of failures (so-called “ST number”) for ending the “probability variation short state” to 10,000 times. Is realized. However, the present invention can be realized even if the number of STs is changed. For example, even if the number of STs is set to less than 10,000, if the number of STs (for example, 1000 times or more) at which the probability of being determined to be a big hit before the end of the “probability variation short state” is very high is set. The frequency at which the ST function operates is extremely low, and the same effect as in the above embodiment can be obtained.
