Various game parts such as a center means 23, a second symbol starting means 24, a plurality (two in this case) of variable winning means 25L and 25R, a first symbol starting means 26, a normal winning means 27, etc. are arranged. Yes.

  The center means 23 is arranged on the upper side of the center in the left-right direction in the game area 22, and a variable display means 28 such as a liquid crystal type is provided at a substantially central portion thereof, and a normal winning means 27 and a first symbol display means 29 are provided at the upper part. Each has it. The variable display means 28 constitutes the second symbol display means 30.

  The first symbol starting means 26 is constituted by a passage gate or the like, and is disposed on the left and right of the center means 23, for example, and detects the game ball when the game ball passes. The first symbol starting means 26 may be constituted by a winning means capable of winning a game ball.

  The 1st symbol display means 29 is comprised by the display means of the 7-segment type etc. which can display 1 or multiple, for example, 1st 1st symbol, The 1st symbol starting means 26 detects a game ball As a result, the first symbol fluctuates for a predetermined time by random number control and stops.

  As the first symbol, a numeric symbol, alphabet symbol, character symbol, and other symbols can be used. In this embodiment, ten types of numeric symbols from “0” to “9” are used. When the first symbol starting means 26 detects a game ball during the fluctuation display of the first symbol display means 29, the detected number is stored up to a predetermined number, for example, four. .

  The second symbol starting means 24 is constituted by an opening / closing prize winning means such as an electric tulip provided with a pair of right and left opening / closing claws 32 that can be freely opened and closed. For example, the second symbol starting means 24 is disposed on the lower side of the center means 23. The opening / closing claw 32 is opened for a predetermined time in the first profit state that is generated on the condition that the stop symbol after the change is displayed on the condition that a predetermined hitting mode is displayed.

  The second symbol display means 30 can variably display one or a plurality of, for example, three second symbols (game symbols) in the left-right direction, for example, at a substantially central portion of the variable display means 28 in the vertical direction. Each second symbol changes in a predetermined variation pattern, such as scrolling up and down or left and right, on the condition that the second symbol starting means 24 detects a game ball, and becomes a predetermined jackpot mode or a disengagement mode. Thus, stop in a predetermined order such as left, right, and middle.

  As the second symbol, a numeric symbol, alphabet symbol, character symbol, and other symbols can be used. In this embodiment, ten types of numeric symbols from “0” to “9” are used. In the present embodiment, 10 types of symbols, ie, “0 · 0 · 0”, “1 · 1 · 1”,...

  Furthermore, the jackpot mode includes a special jackpot mode and other normal jackpot modes. In this embodiment, among the 10 types of jackpot modes, “1 · 1 · 1”, “7 · 7 · 7”, etc. are odd numbers. Five types of jackpot modes consisting of symbols are designated as special jackpot modes, and five types of jackpot modes consisting of even numbers such as “2, 2, 2”, “8, 8, 8”, etc. are designated as normal jackpot modes.

  The variation pattern of the second pattern includes, for example, a reach-less variation pattern that becomes a disengagement mode without going through the reach state, a reach-out variation pattern that becomes a disengagement mode via the reach state, and a jackpot manner via the reach state There are many types such as the reach jackpot variation pattern.

  When the second symbol starting means 24 detects a game ball during the fluctuation display of the second symbol display means 30, the detected number is stored up to a predetermined number, for example, four. .

  The variable winning means 25L and 25R constitute so-called attackers, each of which includes, for example, an open / close plate 33 that can be opened and closed around the horizontal axis on the lower side, and can be converted into an open state advantageous to the player and an unfavorable closed state. It is configured.

  These two variable winning means 25L and 25R are arranged, for example, on the left and right sides of the lower side of the game area 22, and a game ball driven into the left side of the game area 22 due to the arrangement of a game nail (not shown) is variable on the left side. The game balls that have been driven into the winning means 25L on the right side of the game area 22 are guided to the variable winning means 25R on the right side with a high probability.

  Inside the variable winning means 25L, 25R, for example, a plurality of passages such as three are formed, each one of which is a specific area 34. The variable winning means 25L and 25R include specific area passage detection switches 36L and 36R that detect game balls that pass through the specific area 34, and normal winning detection switches 37L that detect game balls that pass through other passages. 37R is provided.

  The variable winning means 25L, 25R is configured such that one of the opening / closing plates 33 has a predetermined upper limit on condition that the stop symbol after the change of the second symbol display means 30 displays a predetermined big hit mode. The game is released until the opening time elapses or a predetermined maximum number of winning game balls are won within the upper limit opening time (second profit state), and a predetermined number of payouts per game ball won during the opening. The award ball is paid out.

  Also, during the second profit state, if the game ball that has won the open variable winning means 25L or 25R passes through the internal specific area 34, the second profit state has a predetermined upper limit number of rounds (for example, 16 rounds). It is designed to be repeated up to the limit.

  In the variable winning means 25L, 25R, the above-described upper limit opening time, upper limit winning number, and payout number are individually set. In this embodiment, the upper limit opening time on the variable winning means 25L side is set to 30 seconds, the upper limit winning number is set to 10 and the payout number is set to 15, and the upper limit opening time on the variable winning means 25R side is set to 15 seconds, the upper limit winning number. Is set to 5 and the number of payouts is set to 10.

  Further, the specific area 34 may be configured such that a plurality of game balls can pass during one round, or closed at the time when one game ball passes, such as a maximum of one game ball per round. You may comprise so that a game ball can pass.

  For example, as shown in FIG. 3, a plurality of opening patterns for defining which of the variable winning means 25L and 25R are to be opened in each round of the second profit state are prepared in advance, and the variable winning means 25L and 25R are The opening / closing control is performed according to any one of the plurality of types of opening patterns A to H.

  For example, the opening pattern A shown in FIG. 3 starts from the variable winning means 25L side from the first round to the sixteenth round of the second profit state and is opened alternately left and right, and similarly the opening pattern B starts from the variable winning means 25R. The opening pattern C starts from the variable winning means 25L and is alternately opened to the left and right by two rounds, and the opening pattern E starts from the first round to the eighth round of the first half to the eighth round. The variable winning means 25R is opened from the ninth round to the sixteenth round, and the opening pattern H is set so that the variable winning means 25R is opened in all rounds.

  Thus, in the present embodiment, the opening switching frequency of the variable winning means 25L, 25R is set so as to decrease from the opening patterns A to H.

  In addition, open notification lamps 35L and 35R are provided in the vicinity of the variable winning means 25L and 25R, for example. These opening notification lamps 35L and 35R constitute notification means for notifying the opening pattern, and when any of the variable winning means 25L and 25R is opened according to a predetermined opening pattern during the second profit state, Prior to opening, the release notification lamp 35L or 35R on the opened side emits light for a predetermined time, for example, to notify the player which of the variable winning means 25L, 25R is open.

  FIG. 4 is a block diagram for control. In FIG. 4, 41 is a main control board, 42 is a sound lamp control board, 43 is a symbol control board, and each of these control boards 41, 42, 43 is a center means 23 mounted in the game area 22, and a plurality of others. It is housed in a board case that is detachably mounted at appropriate places on the back side of the gaming machine main body 1 including the front frame 3 and the game board 12 such as the back side of a back cover that collectively covers individual gaming parts from the back side.

  Note that one-way communication is possible from the main control board 41 to the sound lamp control board 42, and two-way communication is possible between the sound lamp control board 42 and the symbol control board 43. Thereby, a command from the main control board 41 to the symbol control board 43 is transmitted via the sound lamp control board 42.

  The main control board 41 is mainly for controlling game operations and the like on the game board 12 side. The first lottery means 51, the first determination means 52, the first profit state generating means 53, the second lottery means 54, A second determining means 55, a stop symbol form selecting means 56, a variation pattern selecting means 57, an opening pattern determining means 58, a second profit state generating means 59, a special gaming state generating means 60, a control command transmitting means 61, etc. , ROM, RAM, and other electronic components.

  The first lottery means 51 generates, for example, 10 random numbers from 0 to 9 when the probability that the first symbol after change is a hitting mode is 1/10, for example, a predetermined number according to the probability. A random number value is generated, and one of the random number values is randomly selected on condition that the first symbol starting means 26 detects a game ball.

  The first determination means 52 determines whether or not to change the first symbol after the change based on the random number value of the lottery in the first lottery means 51, that is, to make the second symbol starter 24 open. It is for determining whether or not to generate a state, and it is determined whether or not the random number value drawn by the first lottery means 51 matches a predetermined hit state determination value. The judgment result is output.

  The first profit state generating means 53, when the determination result of the first determining means 52 is a hit mode determination, and the first symbol after the change of the first symbol display means 29 is the hit mode, the second symbol starting means 24 The first profit state in which the opening / closing claw 32 is opened for a predetermined time is generated.

  The second lottery means 54 generates a predetermined number of random numbers from 0 to 299, for example, when the probability that the second symbol after the change becomes a big hit mode is 1/300, for example, A random number value is generated, and on the condition that the second symbol starting means 24 detects a game ball, any one of the random number values is selected.

  The second determination means 55 determines whether or not to change the second symbol after change based on the lottery random value in the second lottery means 54, that is, to make the variable winning means 25L and 25R open. It is for determining whether or not to generate a state, and it is determined whether or not the random number value drawn by the second lottery means 54 matches a predetermined jackpot mode determination value. The judgment result is output.

  The stop symbol form selection means 56 is for selecting the stop symbol form after the fluctuation of the second symbol display means 30 based on the determination result of the second determination means 55, and the determination result of the second determination means 55 is One of a plurality of types of big hit modes is selected at the time of the big hit mode determination, and one of a plurality of types of off mode is selected by random number lottery at the time of the off mode determination. In the case of the detachment mode, at least one of the three second symbols is a different symbol.

  The variation pattern selection means 57 alternatively selects one of a plurality of types of variation patterns by random lottery based on at least one of the determination result of the second determination means 55 and the stop symbol mode selection means 56. For example, when the determination result of the second determination means 55 is a jackpot mode determination, any one of a plurality of types of reach jackpot variation patterns in which the second symbol after the change may become a jackpot mode When determining the detachment mode, any one of a reachless detachment variation pattern, a reach detachment variation pattern, or the like in which the second symbol after the variation becomes a detachment mode is selected by random lottery.

  The opening pattern determining means 58 is for determining an opening pattern of the variable winning means 25L, 25R in the second profit state, and includes an opening pattern storage means 62, an opening pattern selection means 63 and the like.

  In the opening pattern storage means 62, opening pattern data corresponding to a plurality of types of opening patterns A to H is stored in advance.

  The opening pattern selection means 63 is for selecting one of the opening patterns A to H stored in the opening pattern storage means 62 when the determination result of the second determination means 55 is the big hit mode determination. For example, one of the open patterns A to H is selected by random number lottery based on the stop symbol mode selected by the stop symbol mode selecting means 56.

  In the present embodiment, as shown in FIG. 5, the selection rates of the open patterns A to H are set to different values depending on whether the stop symbol mode is the normal jackpot mode or the special jackpot mode, and the normal jackpot mode In the case of an open pattern (for example, open patterns A and B) where the frequency of opening and closing of the variable winning means 25L and 25R is higher, the selection rate is higher. Conversely, in the case of a special jackpot mode, the variable winning means 25L and 25R are opened. The open pattern (for example, open patterns G and H) having a low switching frequency has a higher selection rate. Of course, the setting of the selection rate is not limited to this.

  The second profit state generating means 59 is determined by the opening pattern determining means 58 when the determination result of the second determining means 55 is the jackpot mode determination and the stop symbol after the change of the second symbol display means 30 is the jackpot mode. Based on one of the released patterns A to H, the variable winning means 25L and 25R are opened to generate a second profit state advantageous to the player.

  Only one of the variable winning means 25L and 25R is opened according to the opening patterns A to H during the second profit state, and a predetermined upper limit opening time elapses or a predetermined upper limit winning number is reached within the upper limit opening time. When a game ball is won, it is closed, and a predetermined number of prize balls are paid out for each game ball won.

  The second profit state generating means 59 includes profit state continuation means 64 for generating the next profit state based on the establishment of a predetermined condition during the second profit state. If the game ball won in the open variable winning means 25L or 25R passes through the specific area 34, the second profit state is continued up to a predetermined upper limit number of rounds (for example, 16 rounds). ing.

  The special gaming state generating means 60 is for generating a special gaming state advantageous to a player different from the normal gaming state after the end of the second profit state, and is configured by a probability changing means 65. In the probability changing means 65, the determination result of the second determining means 55 is jackpot mode determination, and the stop symbol pattern selecting means 56 selects a special jackpot mode among a plurality of types (10 types) of jackpot modes, On the condition that the second symbol becomes a special jackpot mode (for example, “7, 7, 7”), the probability that the second symbol will be a jackpot mode after the end of the second profit state is set to a normal probability (for example, 1/300). This is for changing from a low probability) to a high probability (for example, about 1/60).

  The probability changing means 65 is configured to increase the probability of occurrence of the jackpot mode by increasing the number of jackpot mode determination values of the second determination means 55 in the high probability state.

  In addition, the probability changing means 65 stops its operation when the second symbol becomes a normal jackpot and the next second profit state occurs or when the second symbol fluctuates a predetermined number of times so far. Thus, the special game state is terminated by returning the occurrence probability of the jackpot mode from the high probability to the normal probability (low probability).

  The control command transmission means 61 is for transmitting a predetermined control command to the sub-control board side such as the voice lamp control board 42 and the symbol control board 43 by one-way communication. The first symbol starting means 26 is a game ball. A function of transmitting a variation control command of the first symbol to the symbol control board 43 side based on the determination result of the first determining means 52, and when the second symbol starting means 24 detects a game ball, A function of transmitting a variation control command of the second symbol to the symbol control board 43 side based on the stop symbol mode selected by the stop symbol mode selecting unit 56, the variation pattern selected by the variation pattern selecting unit 57, etc., and the second profit The function of transmitting the start command of the second profit state to the sound lamp control board 42 based on the operation of the state generating means 59, the opening pattern determined by the opening pattern determining means 58, etc. Based on the variable winning device 25L, and has a function for sending to the voice lamp control board 42 side opening notification command 25R.

  The release notification command for the variable winning means 25L, 25R is transmitted at a predetermined timing before the variable winning means 25L, 25R is opened.

  The sound lamp control board 42 is for performing sound output control, lamp lighting control, and the like, and includes a notifying operation lottery means 71, a notifying control means 72, a not-shown sound control means, a lamp control means, and the like, and a CPU, It is comprised by electronic components, such as ROM and RAM.

  The notification operation lottery means 71 is for drawing whether or not to notify the opening pattern by the opening notification lamps 35L and 35R. For example, based on the start command of the second profit state from the main control board 41 side, A lottery to notify the opening pattern with a predetermined probability is performed.

  In addition, you may make it change the lottery probability of whether to alert | report an open | release pattern according to a gaming state, such as changing with the kind of stop symbol aspect of the 2nd symbol display means 30. Also, lottery may be performed based on the first release notification command from the main control board 41 side instead of the start command of the second profit state from the main control board 41 side.

  The notification control means 72 is for performing light emission control of the release notification lamps 35L and 35R, and when the notification operation lottery means 71 performs a lottery to notify the release pattern, the notification control means 72 from the main control board 41 side. Based on the opening notification command of the variable winning means 25L, 25R, before the variable winning means 25L, 25R is opened, the opening notification lamp 35L or 35R corresponding to the variable winning means 25L or 25R on the opening side is caused to emit light and variable. The player is notified in advance which of the winning means 25L and 25R is to be released.

  The symbol control board 43 is for performing display control of the first symbol display means 29 and the second symbol display means 30, and includes a first symbol control means 73, a second symbol control means 74, etc., and includes a CPU, ROM, It is comprised by electronic components, such as RAM.

  The first symbol control means 73 controls the display of the first symbol display means 29, and the variable control command from the control command transmission means 61 is provided on condition that the first symbol start means 26 detects a game ball. Based on this, the first symbol of the first symbol display means 29 is changed for a predetermined time, and when the determination result of the first determination means 52 is the hit mode determination, the first symbol is stopped in the hit mode.

  The second symbol control means 74 controls the display of the second symbol display means 30, and the variation pattern selected by the variation pattern selection means 57 on condition that the second symbol start means 24 detects a game ball. Accordingly, the second symbol of the second symbol display means 30 is changed for a predetermined time, and is stopped in the stop symbol mode selected by the stop symbol mode selecting unit 56.

  Next, the operation of the pachinko machine will be described. When a game ball is fired by the launching means 13 during the game, the game ball enters the game area 22 through the guide rail 21 and then wins the normal winning means 27 or the like while falling in the game area 22 1 Drops downward while passing through the design starting means 26.

  When the game ball passes through the first symbol starting means 26, the first lottery means 51 draws the generated random number value, and the first determination means 52 determines whether or not it is a winning mode from the lottery random number value, and the determination result Based on the above, the control command transmission means 61 transmits the variation control command of the first symbol to the symbol control board 43 side.

  When the determination result of the first determination means 52 is the hit mode determination, “7” after the first symbol of the first symbol display means 29 fluctuates for a predetermined time by the control of the first symbol control means 73 on the symbol control board 43 side. Stop in the hit mode. Then, by the control of the first profit state generating means 53, the opening / closing claw 32 of the second symbol starting means 24 is opened for a predetermined time, and it becomes easy for the game balls to win the second symbol starting means 24. In addition, if the determination result of the 1st determination means 52 is other than a hit aspect determination, the 1st symbol after a fluctuation | variation will stop in a deviating aspect, and the 1st profit state generation means 53 will not operate | move.

  When the opening / closing claw 32 of the second symbol starting means 24 is opened and a game ball is won, and when the second symbol starting means 24 detects a gaming ball, the second lottery means 54 draws the generated random number value and performs the second determination. It is judged whether the means 55 is a big hit mode from the lottery random number value.

  And when the determination result of the 2nd determination means 55 becomes the big hit mode determination, the stop symbol mode selection means 56 became one of the multiple types (10 types) of big hit modes as the off mode determination. In this case, one of a plurality of types of detachment modes is selected by random lottery, and the variation pattern selection unit 57 selects at least one of the determination result of the second determination unit 55 and the selection result of the stop symbol mode selection unit 56. Based on the above, one of a plurality of types of variation patterns is selected by random lottery, and the control command transmission means 61 transmits the variation control command of the second pattern via the sound lamp control board 42 by one-way communication. It transmits to the symbol control board 43 side, and commands change, stop, etc. of the second symbol.

  In addition, when the determination result of the second determination unit 55 is the jackpot mode determination, the release pattern selection unit 63 of the release pattern determination unit 58 is based on the stop symbol mode selected by the stop symbol mode selection unit 56. One of the open patterns A to H is selected by random number lottery.

  For example, as shown in FIG. 5, when the stop symbol mode selected by the stop symbol mode selection unit 56 is a normal big hit mode such as “6, 6, 6”, the switching frequency of the variable winning units 25L and 25R is A higher open pattern (for example, open patterns A and B) is selected with a higher probability, and is variable when the stop symbol mode selected by the stop symbol mode selection means 56 is a special jackpot mode such as “7, 7, 7”. An open pattern (for example, open patterns G and H) having a lower switching frequency of the winning means 25L and 25R is selected with a higher probability.

  On the symbol control board 43 side, when the variation control command is received from the control command transmission unit 61, the second symbol control unit 74 determines the second symbol of the second symbol display unit 30 according to the variation pattern selected by the variation pattern selection unit 57. After changing for a predetermined time, it is stopped in the big hit mode or the off mode selected by the stop symbol mode selection means 56.

  And if the stop symbol after the change of the 2nd symbol display means 30 is decided in the big hit mode, while the start command of the 2nd profit state will be transmitted to the voice lamp control board 42 side, the 2nd profit state generating means 59 will be The second profit state is generated according to any one of the opening patterns A to H selected by the opening pattern selection means 63.

  That is, first, the variable winning means 25L or 25R on the side designated in the first round of the opening pattern is opened. Then, the opened variable winning means 25L or 25R is closed and won when a predetermined upper limit opening time elapses from the opening or when a predetermined upper limit number of game balls wins within the upper limit opening time. A predetermined number of prize balls are paid out per game ball.

  When the game ball that has won the variable winning means 25L or 25R passes through the specific area 34 during the opening (during the second profit state), it is subsequently designated in the second round of the opening pattern. The variable winning means 25L or 25R on the side is opened. This second profit state is repeated up to a predetermined upper limit number of rounds (for example, 16 rounds).

  Further, when the second profit state generating means 59 operates, based on the opening pattern determined by the opening pattern determining means 58, etc., at a predetermined timing before each round of the second profit state starts. The opening notification command of the variable winning means 25L, 25R is transmitted from the control command transmitting means 61 side to the sound lamp control board 42 side.

  On the sound lamp control board 42 side, for example, based on the start command for the second profit state from the main control board 41 side, the notification operation lottery means 71 performs a lottery to notify the opening pattern with a predetermined probability. When the notification operation lottery means 71 performs a lottery to notify the release pattern, the notification control means 72 is based on the release notification command from the main control board 41 side, and the variable winning means 25L, 25R. Before the opening, the release notification lamp 35L or 35R corresponding to the variable winning means 25L or 25R on the opening side is caused to emit light to notify the player in advance which of the variable winning means 25L or 25R is open.

  In FIG. 6, the determination result of the second determination unit 55 is the jackpot mode determination, the stop symbol mode selection unit 56 selects “6, 6, 6”, which is the normal jackpot mode, and the release pattern determination unit 58 selects the release pattern A. Is selected and the notification operation lottery means 71 performs the lottery to notify, the fluctuation of the second symbol display means 30, the on / off of the release notification lamps 35L and 35R, the variable winning means 25L and 25R FIG. 6 shows an example of each history of an open / close state, a detection state of the normal winning detection switches 37L and 37R, and a detection state of the specific area passage detection switches 36L and 36R.

  When the second symbol of the second symbol display means 30 stops at “6, 6, 6”, which is a normal big hit mode (a1), according to the opening pattern A, the opening notification lamp 35L is first lit and the variable winning means 25L is opened. After notifying the player that the variable winning means 25L is opened, the second profit state of the first round is started (a2). The player operates the launch handle 14 to drive the game ball into the left side of the game area 22 in advance by aiming at the variable winning means 25L side by lighting the release notification lamp 35L.

  The variable winning means 25L during the opening, for example, 10 game balls as the upper limit winning number wins until the upper limit opening time of 30 seconds elapses, and the normal winning detection switch 37L and the specific area passing detection switch 36L. Is closed when the detection signal is output a total of 10 times, and the second profit state of the first round is terminated (a4). It should be noted that 15 winning balls are paid out for each winning game ball to the variable winning means 25L.

  When the game ball passes through the specific area 34 during the second profit state of the first round and a detection signal is output from the specific area passage detection switch 36L (a3), this time, according to the opening pattern A, the opening notification lamp After 35R is lit and the player is informed in advance that the variable winning means 25R is released (a4), the variable winning means 25R is opened and the second profit state of the second round is started (a5). The player operates the firing handle 14 to drive the game ball to the right side of the game area 22 in advance by aiming at the variable winning means 25R side in advance by lighting the release notification lamp 35R.

  The open variable winning means 25R is closed when, for example, five game balls as the upper limit winning number are won before 15 seconds as the upper limit opening time elapses, and the second profit state in the second round is set. End (a7). In addition, 10 prize balls are paid out per prize for the winning of game balls to the variable winning means 25R.

  When the game ball passes through the specific area 34 during the second profit state of the second round and a detection signal is output from the specific area passage detection switch 36R (a6), the release notification lamp 35L is again provided according to the release pattern A. Is turned on and the player is informed in advance that the variable winning means 25L is released (a7), and then the variable winning means 25L is opened and the second profit state of the third round is started (a8).

  The open variable winning means 25L is closed at the time when the upper limit opening time of 30 seconds elapses before, for example, ten game balls that are the upper limit winning number win, and the second round of the second round. The profit state ends (a9). If the game ball has not passed the specific area 34 during the second profit state of the third round, the lighting of the release notification lamp 35R corresponding to the subsequent fourth round and the subsequent opening of the variable winning means 25R are performed. At that time, the operation of the second profit state generating means 59 ends.

  In FIG. 7, the determination result of the second determination means 55 is the jackpot mode determination, the special symbol pattern “7 · 7 · 7” is selected by the stop symbol mode selection means 56, and the release pattern E is determined by the release pattern determination means 58. Is selected and the notification operation lottery means 71 performs the lottery to notify, the fluctuation of the second symbol display means 30, the on / off of the release notification lamps 35L and 35R, the variable winning means 25L and 25R FIG. 6 shows an example of each history of an open / close state, a detection state of the normal winning detection switches 37L and 37R, and a detection state of the specific area passage detection switches 36L and 36R.

  When the second symbol of the second symbol display means 30 stops at “7, 7, 7”, which is a special jackpot mode (b1), according to the opening pattern E, the opening notification lamp 35L is first lit and the variable winning means 25L is opened. After notifying the player beforehand, the variable winning means 25L is opened and the second profit state of the first round is started (b2). The player operates the launch handle 14 to drive the game ball into the left side of the game area 22 in advance by aiming at the variable winning means 25L side by lighting the release notification lamp 35L.

  The variable winning means 25L during the opening, for example, 10 game balls as the upper limit winning number wins until the upper limit opening time of 30 seconds elapses, and the normal winning detection switch 37L and the specific area passing detection switch 36L. When the detection signal from is output a total of 10 times, it is closed and the second profit state of the first round ends (b3).

  When the game ball passes the specific area 34 during the second profit state of the first round and a detection signal is output from the specific area passage detection switch 36L (b3), the same as the first round according to the release pattern E After the opening notification lamp 35L is lit and the player is informed in advance that the variable winning means 25L is open, the variable winning means 25L is opened and the second profit state of the second round is started (b4). The player may operate the launch handle 14 to drive the game ball to the left side of the game area 22 aiming at the variable winning means 25L side following the first round by turning on the release notification lamp 35L.

  The open variable winning means 25L is closed when the upper limit opening time of 30 seconds elapses before the ten game balls that are the upper limit winning number wins, and the second profit state of the second round is ended. (B5).

  The same process is repeated until the 8th round, and when the game ball passes through the specific area 34 and the detection signal is output from the specific area passage detection switch 36L during the second profit state of the 8th round, it is released. According to the pattern E, after the opening notification lamp 35R is turned on and the player is notified in advance that the variable winning means 25R is opened (b6), the variable winning means 25R is opened and the second profit of the ninth round is opened. The state starts (b7). The player operates the firing handle 14 to drive the game ball to the right side of the game area 22 in advance by aiming at the variable winning means 25R side in advance by lighting the release notification lamp 35R.

  The open variable winning means 25R is closed when, for example, five game balls as the upper limit winning number wins before the upper limit opening time of 15 seconds elapses, and the second profit state of the ninth round is reached. Is finished (b8).

  When the game ball passes through the specific area 34 and the detection signal is output from the specific area passage detection switch 36R during the second profit state of the ninth round (b8), the release notification lamp 35R is again made according to the release pattern E. Is turned on and the player is informed in advance that the variable winning means 25R is opened, and then the variable winning means 25R is opened and the second profit state of the tenth round is started (b9). The player may operate the launch handle 14 to drive the game ball to the right side of the game area 22 aiming at the variable winning means 25R side following the ninth round by turning on the release notification lamp 35R.

  When the same process is repeated up to the 16th round, which is the upper limit number of rounds, the operation of the second profit state generating means 59 ends when the second profit state of the 16th round ends (b10).

  When the stop symbol after the fluctuation of the second symbol display means 30 becomes a special jackpot mode of the jackpot mode, the probability changing unit 65 of the special gaming state generating unit 60 is activated after the end of the second profit state. Thus, a special gaming state is generated, and the probability of occurrence of the jackpot mode is changed from a normal probability to a high probability. After that, since the second determination means 55 determines whether or not the big hit mode is set in a high probability state, the possibility that the second symbol after the change becomes the big hit mode again becomes very high, and the player is advantageous. You can play games in the state.

  This special gaming state is ended when the second symbol after the change becomes a normal jackpot and the next second profit state occurs, or when the second symbol fluctuates a predetermined number of times so far, The occurrence probability of the big hit mode returns from the high probability to the normal probability.

  As described above, the present embodiment includes a plurality of variable winning means 25L and 25R, and the opening pattern determining means 58 releases the plurality of variable winning means 25L and 25R in the second profit state one or more times. Since the pattern is determined, the opening pattern of the variable winning means 25L, 25R when the second profit state occurs is rich in change, and the player needs to adjust the launch operation according to the opening pattern. Therefore, more interesting games are possible.

  Further, since any one of the plurality of variable winning means 25L and 25R is in the open state during the second profit state, the winning probability of the game ball in the second profit state is variable. This can be made substantially the same as when there is only one winning means.

  Since the player is provided with release notification lamps 35L and 35R for notifying the release pattern determined by the release pattern determination means 58 before the variable winning means 25L and 25R are opened, the player next selects a plurality of variable winning means 25L and 25R. You can know in advance which will be released. Thereby, it becomes easy to win the game ball in the specific area 34 and continue the second profit state.

  The release pattern determining means 58 relates the symbol variation of the second symbol display means and the opening of the variable winning means 25L, 25R in order to determine the release pattern based on the stopped symbol form after the fluctuation of the second symbol display means 30. And the production effect can be further enhanced.

  Furthermore, when the second symbol is in a special jackpot mode, since the opening pattern with the low switching frequency of the variable winning means 25L, 25R is selected with a high probability, the second symbol is special. In the big hit mode, the player does not need to switch between right-handed and left-handed while the second profit state is continued, and can easily receive the return of profit.

  8 and 9 exemplify the second embodiment of the present invention, in which the opening pattern determination means 58 is played in the next round based on the winning of the game ball to the variable winning means 25L, 25R in the second profit state. An example is shown in which the variable winning means to be opened is determined.

  The opening pattern determining means 58 of the present embodiment does not determine the opening patterns for all rounds of the second profit state that occur after the second profit state generating means 59 starts operating, but instead of determining the second profit state. When each round of the state is started, it is determined which of the variable winning means 25L, 25R is to be released in the round, the release rule storage means 81, the timer means 82, the release selection means. 83 and the like.

  The release rule storage means 81 is for storing in advance a release rule for determining a variable winning means to be released in the next round of the second profit state. This release rule is defined such that, for example, the variable winning means to be released in the next round is determined according to the winning of the game ball to the variable winning means 25L, 25R in the second profit state.

  The release rule in the present embodiment is that the duration of each round in the second profit state, that is, the opening time of the variable winning means 25L, 25R is a predetermined time (for example, the variable winning means 25L is 15 seconds and the variable winning means 25R is 8 seconds). Etc.), the variable winning means released in the round are continuously released in the next round, and when the predetermined time is exceeded, the variable winning means different from the variable winning means released in the round is released. It is prescribed as follows.

  In addition, the variable winning means to be released in the first round of the second profit state may be determined based on, for example, random number lottery, stop symbol form of the second symbol, etc. In the release rule of the present embodiment, If the stop symbol mode is a normal jackpot mode, the variable winning means 25L is selected. If the stop symbol mode is a special jackpot mode, the variable winning means 25R is selected.

  The timer means 82 measures the duration of each round in the second profit state, that is, the opening time of the variable winning means 25L, 25R.

  The opening selection means 83 is for selecting which of the variable winning means 25L and 25R is to be released in each round when the second profit state round is started. One of the variable winning means 25L and 25R is selected based on the release rule stored in the above and the time measured by the timer means 82 in the previous round.

  Further, the control command transmission means 61 sends a sound lamp from the control command transmission means 61 side at a predetermined timing before each round of the second profit state starts based on the determination result of the release pattern determination means 58. An opening notification command for the variable winning means 25L, 25R is transmitted to the control board 42 side.

  In FIG. 9, the determination result of the second determination means 55 is a jackpot mode determination, the special symbol pattern “7 · 7 · 7” is selected by the stop symbol mode selection means 56, and the notification operation lottery means 71 performs notification. When the lottery is performed, the second symbol display means 30 changes, the open notification lamps 35L and 35R are turned on / off, the variable winning means 25L and 25R are opened and closed, and the normal winning detection switches 37L and 37R are detected. 4 shows an example of each history of detection states of the specific area passage detection switches 36L and 36R.

  When the second symbol of the second symbol display means 30 stops at “7, 7, 7”, which is a special jackpot mode (c1), first, the release notification lamp 35R is turned on and the variable winning means 25R is released. In advance, the variable winning means 25R is opened, the second profit state of the first round is started (c2), and the timer means 82 starts measuring time.

  The variable winning means 25R that is being opened, for example, receives five game balls as the upper limit winning number before the upper limit opening time of 15 seconds elapses, and the normal winning detection switch 37R and the specific area passing detection switch 36R. When the detection signal from is output five times in total, it is closed and the second profit state of the first round is completed (c4), and the timer means 82 is stopped.

  When the game ball passes through the specific area 34 during the second profit state of the first round and a detection signal is output from the specific area passage detection switch 36R (c3), the time count of the previous round by the timer means 82 Is 7 seconds, which is shorter than the predetermined time of 8 seconds, for example, the opening selection means 83 selects the variable winning means 25R opened in the previous round. Then, after the release notification lamp 35R, which is the same as that in the first round, is turned on and the player is informed in advance that the variable winning means 25R is open (c4), the variable winning means 25R is opened and the second round of the second winning means 25R is released. 2 When the profit state starts (c5), the timer means 82 newly starts counting time.

  The variable winning means 25R that is being opened, for example, receives five game balls as the upper limit winning number before the upper limit opening time of 15 seconds elapses, and the normal winning detection switch 37R and the specific area passing detection switch 36R. When the detection signal from is output five times in total, it is closed and the second profit state of the second round is completed (c7), and the timer means 82 is stopped.

  When the game ball passes through the specific area 34 during the second profit state of the second round and a detection signal is output from the specific area passage detection switch 36R (c6), the time measured by the timer means 82 in the previous round Is 9 seconds longer than the predetermined time of 8 seconds, for example, the release selection means 83 selects the variable winning means 25L different from the variable winning means 25R released in the previous round. In response to this, the release notification lamp 35L is lit to notify the player in advance that the variable winning means 25L is open (c7), and then the variable winning means 25L is opened and the second profit of the third round is released. As the state starts (c8), the timer means 82 newly starts counting time.

  For example, the variable winning means 25L that is being opened receives, for example, 10 game balls that are upper limit winning numbers before the upper limit opening time of 30 seconds elapses, and a normal winning detection switch 37L and a specific area passing detection switch 36L. When the detection signal from is output a total of 10 times, it is closed and the second profit state of the third round is completed (c10), and the timer means 82 is stopped.

  When the game ball passes through the specific area 34 during the second profit state of the third round and a detection signal is output from the specific area passage detection switch 36L (c9), the time count of the previous round by the timer means 82 Is 13 seconds, which is shorter than the predetermined time of 15 seconds, for example, the release selection means 83 selects the variable winning means 25L that was released in the previous round. Then, after the opening notification lamp 35L, which is the same as that in the third round, is turned on and the player is informed in advance that the variable winning means 25L is opened (c10), the variable winning means 25L is opened and the fourth round As the 2 profit state starts (c11), the timer means 82 newly starts timing.

  For example, the variable winning means 25L that is being opened receives, for example, 10 game balls that are upper limit winning numbers before the upper limit opening time of 30 seconds elapses, and a normal winning detection switch 37L and a specific area passing detection switch 36L. When the detection signal from is output a total of 10 times, it is closed and the second profit state of the fourth round ends (c13), and the timer means 82 stops.

  When the game ball passes through the specific area 34 and the detection signal is output from the specific area passage detection switch 36L during the second profit state of the fourth round (c12), the time count of the previous round by the timer means 82 Is 18 seconds longer than the predetermined time of 15 seconds, for example, the release selection means 83 selects the variable winning means 25R different from the variable winning means 25L released in the previous round. Then, in response to this, the release notification lamp 35R is lit to notify the player in advance that the variable winning means 25R is open (c13), and then the variable winning means 25R is opened and the second profit of the fifth round is released. As the state starts (c14), the timer means 82 newly starts counting time.

  Similar processing is repeated up to a predetermined upper limit number of rounds (for example, 16 rounds) on condition that the game ball passes through the specific area 34 during the second profit state.

  As described above, the opening pattern determining means 58 is configured to determine the variable winning means to be released in the next round based on the winning of the game ball to the variable winning means 25L, 25R in the second profit state. Thus, the gaming state during each round can be reflected in the opening pattern of the variable winning means 25L, 25R in the next and subsequent rounds, and a more varied effect can be achieved.

  As mentioned above, although each embodiment of this invention was explained in full detail, it is not limited to each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, three or more variable winning means may be provided. The variable winning means need not be arranged in the left-right direction, and can be arranged arbitrarily, for example, arranged on the upper side and the lower side of the game area 22.

  The variable winning means may adopt any configuration such as an electric tulip type having a pair of left and right opening / closing means.

  For example, when a plurality of variable winning means are arranged in the left-right direction, the game area 22 is divided into a plurality of areas in the left-right direction corresponding to the variable winning means, and the game balls that are driven into each area are within that area. It may be possible to win only the variable winning means. The area may be divided according to the arrangement of game nails and the arrangement of game parts.

  The opening notification lamps 35L and 35R as notification means for notifying the opening pattern of the variable winning means may be provided on the variable winning means, or may be provided, for example, on the center means 23 away from the variable winning means.

  In addition, the notification means for notifying the opening pattern of the variable winning means is a predetermined display (for example, arrow display, word display such as “left” and “right”, character display, For displaying moving images, etc.), by voice, or by moving a movable object.

  As a predetermined condition for the profit state continuation means 64 to continuously generate the second profit state, in addition to winning a game ball to the specific area 34, a game ball within a predetermined time from the opening of the variable winning means 25L, 25R It may be a prize. In this case, if the predetermined time is set to be shorter than the time required for winning from the launch to the variable winning means 25L, 25R, it becomes difficult to continue the second profit state when the notifying means is not operating, and conversely, When the means is activated, it is easy to continue the second profit state. Therefore, the profit given to the player can be significantly changed depending on whether or not the notifying means is activated.

  The plurality of variable winning means 25L and 25R may set the upper limit opening time, the upper limit winning number, the number of payouts, etc. all to the same value, or only some of them may be set to different values. In addition, the setting contents such as the upper limit opening time, the upper limit winning number, the number of payouts, etc. are variable, and are changed according to random number lottery, time passage, stop pattern mode of the first symbol and second symbol, variation pattern, and other game conditions. You may do it.

  The opening pattern is not limited to that shown in FIG. 3 and can be arbitrarily set. Further, the selection rate of each open pattern can be set arbitrarily. For example, the select rates of all open patterns may be the same. You may make it change the setting content of the selection rate of each open pattern according to fluctuation patterns other than a stop symbol aspect, random number lottery, etc., for example. Moreover, you may provide the open | release pattern selected only when specific conditions are satisfied (for example, when it becomes a special jackpot mode etc.).

  When determining the variable winning means to be released for each round of the second profit state as in the second embodiment, the variable winning means to be released in the next round is determined based on the duration of the previous round. For example, the number of game balls won in the previous round, the number of wins in the specific area 34 in the previous round (when a plurality of game balls can be won in the specific area 34), how many balls have won the specific area 34, The determination may be made based on a random number lottery or the like based on winning in the specific area 34.

  In the embodiment, the main control board 41 and the sound lamp control board 42 are connected so as to be capable of one-way communication, and the sound lamp control board 42 and the symbol control board 43 are connected so as to be capable of two-way communication. And the symbol control board 43 may be connected so that one-way communication is possible, and the symbol control board 43 and the sound lamp control board 42 may be connected so that bidirectional communication is possible. Further, the sound lamp control board 42 and the symbol control board 43 may be individually connected to the main control board 41.

  The sound lamp control board 42 and the symbol control board 43 may be constituted by one sub control board. Further, the sound lamp control board 42 may be separately provided, for example, as a sound control board and a lamp control board. In this case, the notification operation lottery means 71, the notification control means 72, and the like may be provided on the voice control board, the lamp control board, and any other sub-control board. Of course, the notification operation lottery means 71, the notification control means 72, etc. may be provided on the main control board 41.

  As the special game state generated by the special game state generating means 60, for example, the variation time of the second symbol is shorter than that in the normal state, in addition to the probability that the second symbol will be a big hit mode higher than the normal state. What makes the opening time of the 2nd symbol starting means 24 longer than the normal state, What makes the probability that the 1st symbol hits higher than the normal state, and makes the variation time of the 1st symbol a normal state That increase the maximum number of rounds for opening the variable winning means 25L and 25R, increase the upper limit opening time for the variable winning means 25L and 25R, and increase the upper limit for the number of variable winning means 25L and 25R. Various profit states are used, such as those for increasing the upper limit reserved number of the first symbol starting means 26, those for increasing the upper limit reserved number of the second symbol starting means 24, etc. Door can be. Further, these plural types of profit states may be generated simultaneously or individually.

  Furthermore, in the embodiment, a pachinko machine has been described as an example, but it goes without saying that the present invention can be similarly applied to other ball game machines such as an arrange ball machine and a sparrow ball game machine.
