Hereinafter, a ball game machine according to an embodiment of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a front view of a ball game machine 1 according to an embodiment of the present invention. FIG. 2 is a front view of the game board 2.
The ball game machine 1 includes a game board 2 (see FIG. 2) for playing a game by dropping a game ball launched from a launching device (launching means, not shown) along the board surface, and a game board 2 A front frame 3 having a substantially rectangular shape in front view to be held and a front door 4 covering the entire front surface of the front frame 3 are provided. The front door 4 can be opened and closed with respect to the front frame 3 around the left edge.

  The lower part of the front frame 3 receives and stores an upper plate 5 for storing game balls (pachinko balls) to be launched toward the game board 2 and game balls that cannot be stored in the upper plate 5. And a lower plate 6 for keeping it. A supply port (not shown) through which game balls overflowing from the upper plate 5 are supplied is formed above the lower plate 6. On the lower surface of the lower plate 6, a discharge port (not shown) for discharging game balls stored in the lower plate 6 is formed. This discharge port is normally covered, and when the discharge lever 9 protruding from the lower front of the lower plate 6 is operated to open the discharge port, the game balls in the lower plate 6 are moved downward from the discharge port. To be discharged.

  On the right side of the lower plate 6, a handle 10 for adjusting the momentum of the game ball launched toward the game board 2 is disposed. The handle 10 is rotatably held by the front frame 3. When the handle 10 is rotated while the game balls are stored in the upper plate 5, a launching device (not shown) is activated, and the game balls in the upper plate 5 are taken into the launching device one by one. Fired from the launch device toward the surface of the game board 2.

The front door 4 is formed with, for example, a substantially circular (ellipse having a long axis in the vertical direction) opening 11. For example, the opening 11 is covered with a transparent plate 12 such as a glass plate at the rear, and when the front door 4 is closed, the game board 2 provided behind the opening 11 can be visually recognized through the transparent plate 12. It is like that.
In the upper left portion and the upper right portion of the front door 4, sound generating means 13 including, for example, a speaker for outputting sound is provided. During the game in the bullet ball gaming machine 1, the game atmosphere can be raised by the sound output from the sound generation means 13. The sound generating means 13 generates (outputs) a sound having contents corresponding to the display contents of an effect display means (decorative member, first notifying means, second notifying means) 15 to be described later during the jackpot game (special game state). To do.

  On the board surface of the game board 2, a substantially arc-shaped guide rail 14 for guiding a game ball launched from a launching device (not shown) to the upper left portion of the game board 2 is disposed. A large number of obstacle nails (not shown) are arranged on the surface of the game board 2, and a game ball released from the upper left portion of the game board 2 toward the upper right side along the guide rail 14 is Along the board surface of the game board 2, it falls through a number of obstacle nails. On the board surface of the game board 2, a game area S in which a game ball can flow down is formed.

  In the central part of the game board 2, for example, an effect display means 15 constituted by a liquid crystal display is arranged. The effect display means 15 provides an effect according to the progress of the game during the game. Specifically, a plurality of effect symbols are variably displayed (high-speed scroll display) in response to a symbol variation operation of the normal symbol display means 31 described later. Further, during a jackpot game, which will be described later, an effect indicating that the game is a jackpot game (an effect corresponding to a special prize opening game) is displayed. In other words, the effect indicating that the jackpot game is being played is displayed with priority over the variation display (high-speed scroll display) of the effect symbol. The display screen of the effect display means 15 is surrounded by a frame (not shown). A decorative member 16 having a motif of a catch from the Edo period, such as ten hands, is attached to the front surface of the frame. Further, an effect lamp (decorative member) 17 for exciting the game is disposed at the center in the left-right direction above the effect display means 15 in the frame. The effect lamp 17 is turned on / off in a manner corresponding to the display content of the effect display means 15 during the big hit game.

A normal symbol start port 18 through which a game ball falling along the board surface of the game board 2 can enter (pass) is disposed immediately below the effect display means 15 on the board surface of the game board 2 and in the center in the left-right direction. Yes. A normal symbol starter sensor 20 (design starter, see FIG. 3) is disposed in the normal symbol starter 19 that defines the normal symbol starter 18. The game ball that has entered the normal symbol starting port 18 passes in the vicinity of the normal symbol starting port sensor 20 immediately after entering the normal symbol starting port 18, and the passage is detected by the normal symbol starting port sensor 20. It has become so. When detecting the game ball, the normal symbol start port sensor 20 outputs a detection signal to a main control board 40 (see FIG. 3) described later. In response to the game ball entering the normal symbol start port 18, a special symbol start port opening game (to be described later) for opening the special symbol start port (first opening / closing prize winning means ) 21 described below in a predetermined manner is executed. A normal symbol lottery for determining whether or not to do is executed.

A special symbol starting port 21 and a special winning opening (second opening / closing winning means ) 22 are arranged vertically below the normal symbol starting port 18 on the surface of the game board 2. A special winning opening 22 is arranged below the special symbol starting port 21. In other words, the special symbol starting port 21 and the special winning port 22 sandwich the special symbol starting port 21 in the vertical direction.
The special symbol starting port 21 has, for example, a rectangular shape that is long on the left and right, and is formed in a size that allows a plurality (3 to 4) of game balls to enter simultaneously. In relation to the special symbol start port 21, a first opening / closing plate 23 capable of opening and closing the special symbol start port 21 is disposed. The first opening / closing plate 23 closes the special symbol start port 21 in a state along the board surface of the game board 2 and can prevent the game ball from entering the special symbol start port 21. The special symbol start port 21 is opened by tilting to the near side about a rotating shaft (not shown) arranged along the lower end edge of the symbol start port 21 and dropped to the special symbol start port 21. The coming game ball can be introduced into the special symbol starting port 21. The game ball that has entered the special symbol starting port 21 falls into a ball collection path (not shown), and is collected into the ball game machine 1 through this ball collection path. A special symbol starting port sensor 24 (symbol starting means; see FIG. 3) is interposed in the middle of the ball collection path. When the game ball passes through the special symbol start port sensor 24 in the ball collection path (that is, when the special symbol start port sensor 24 detects the game ball), the special symbol start port sensor 24 detects the main control board 40 (FIG. 3). The detection signal is output in response to the reference. When a game ball enters the special symbol starting port 21, a predetermined number (for example, 10 balls) of prize balls are paid out from a prize ball payout device (not shown). The game balls paid out from the prize ball payout device are supplied to the upper plate 5. Since the first opening / closing plate 23 closes the special symbol starting port 21 in a state along the board surface of the game board 2, when the first opening / closing plate 23 is closed, the special symbol starting port 21 is allowed to enter the game ball. I can't.

  In addition, a special symbol lottery for determining whether or not to execute a special prize opening opening game in which the special prize opening 22 is opened in a predetermined manner according to the game ball entering the special symbol start opening 21 is executed. Is done. The probability determined to open the special prize opening 22 by the special symbol lottery is a predetermined high probability (1/1) in the probability variation mode to be described later, and a mode that is not the probability variation mode (time reduction mode to be described later or described later). A low probability (for example, 999/1000) set in advance during the normal mode).

  The special winning opening 22 has, for example, a rectangular shape that is long on the left and right, and is formed in a size that allows a plurality of game balls (3 to 4) to enter simultaneously. The special winning opening 22 is formed in substantially the same size as the special symbol starting port 21 in the left-right direction. The left and right ends of the special winning opening 22 are aligned with the left and right ends of the special symbol start opening 21 in the left-right direction. A second opening / closing plate 25 for opening and closing the special winning opening 22 is provided in association with the special winning opening 22.

  The second opening / closing plate 25 closes the special prize opening 22 in a state along the board surface of the game board 2 and can prevent the game balls from entering the special prize opening 22. By tilting forward about a pivot shaft (not shown) arranged along the lower edge of 22, the special prize opening 22 is opened and the game ball falling to the special prize opening 22 is special. It can be introduced into the winning opening 22. The game balls that have entered the special winning opening 22 fall into a ball collection path (not shown) and are collected through the ball collection path into the ball game machine 1. A special prize opening sensor 26 (see FIG. 3) is interposed in the middle of the ball collection path. When the game ball passes through the special prize port sensor 26 in the ball collection path (that is, when the special prize port sensor 26 detects the game ball), the special prize port sensor 26 is connected to a main control board 40 (see FIG. 3) described later. In response, a detection signal is output. When a game ball enters the special winning opening 22, a predetermined number of prize balls (for example, three balls) are paid out from a prize ball payout device (not shown). The game balls paid out from the prize ball payout device are supplied to the upper plate 5. The number of prize balls (for example, 3 balls) to be paid out for entering the special winning opening 22 is smaller than the number of prize balls (for example, 10 balls) to be paid out for entering the special symbol starting port 21. Is set. Since the second opening / closing plate 25 closes the special winning opening 22 in a state along the board surface of the game board 2, it is not possible to allow a game ball to enter the special winning opening 22 when the second opening / closing plate 25 is closed. .

  In the special prize opening game, the special prize opening 22 is kept until a predetermined short time (for example, 0.5 seconds) elapses or until a predetermined number (for example, two balls) of game balls enter the special prize opening 22. This operation is performed for a small number of rounds (for example, 2 rounds) with an interval of a predetermined time (for example, 2.0 seconds) (hereinafter referred to as this round). The special prize opening game of the specification may be expressed as “0.5 seconds × 2R”). Since the opening time of the special prize opening 22 in each round of this special prize opening game is short (for example, 0.5 seconds), in one special prize opening game, a small number of game balls (on average, For example, about 2 game balls enter. Since the number of prize balls to be paid out to the special prize opening 22 is small (for example, 3 balls), there are very few prize balls that a player can acquire in the special prize opening game. In other words, although the special prize opening game is a special symbol profit state, it does not give a large profit directly to the player. The state in which the special prize opening game is executed is referred to as “special profit state”.

  A normal symbol start gate 27 through which a game ball falling along the board surface of the game board 2 can pass is disposed on the right part of the game board 2 (to the right of the effect display means 15). The game ball that has passed through the normal symbol start gate 27 is detected by a normal symbol start gate sensor 28 (symbol start means, see FIG. 3). When the normal symbol start gate sensor 28 detects a game ball, it outputs a detection signal to a main control board 40 (see FIG. 3) described later. In accordance with the passage of the game ball to the normal symbol start gate 27, it is determined whether or not to execute a special symbol start port opening game (displacement means operation game) that opens the special symbol start port 21 in a predetermined manner. Normal symbol lottery is executed. That is, the normal symbol lottery is executed both when the game ball enters the normal symbol start port 18 and when the game ball passes through the normal symbol start gate 27. The probability determined to open the special symbol start port 21 by the normal symbol lottery is a predetermined high probability (1/1) in the probability variation mode described below and the time reduction mode described below, and the normal mode described below. Inside, a low probability (1/300) determined in advance.

In the special symbol start opening game, such an operation of opening the special symbol start port 21 once until a predetermined time (for example, 3.0 seconds) elapses is performed for a predetermined time (for example, 2.. Repeated twice with an interval of 0 seconds (hereinafter, the special symbol start opening game of this specification may be expressed as “3.0 seconds × 2 times”). Since the special symbol starting port 21 is formed in a size that allows a plurality of (3-4) game balls to enter simultaneously, and the opening time of the special symbol starting port 21 is 6.0 seconds in total. In this special symbol starting port opening game, it is easy for a game ball flowing down along the surface of the game board 2 to enter the special symbol starting port 21. Therefore, a large number (for example, about 10) of game balls enter in one special symbol start opening game. That is, the number of game balls that enter the special symbol start port 21 or the special winning port 22 is larger in the special symbol starting port opening game than in the special winning port opening game. Then, the number of prize balls (for example, 10 balls) to be paid out for entering the special symbol starting port 21 is the number of prize balls (for example, 3 balls) to be paid out for entering the special prize opening 22. ) Is set to be more. Accordingly, the special symbol start opening game is higher than the profit given to the player than the special prize opening opening game. This special symbol start opening game is executed independently of the special prize opening opening game.
The state in which the special symbol start opening game is executed is called “ordinary profit state”.

In the ball game machine 1, a probability variation mode, a time reduction mode (high probability mode), and a normal mode are prepared. The normal mode is a mode that is neither the probability variation mode nor the time reduction mode. In the ball game machine 1, the probability variation mode, the time reduction mode, and the normal mode can be selectively executed.
In the probability variation mode, the winning probability of the special symbol lottery is set to a high probability (for example, 1/1), and the winning probability of the normal symbol lottery is set to a high probability (for example, 1/1). In this ball game machine 1, a so-called probability variation mode with a limiter is employed. Therefore, when the number of times that the probability variation mode is continuously executed (hereinafter also referred to as “probability variation continuous execution number”) reaches a predetermined limit number, the probability variation mode is not executed after the next time, The short time mode or the normal mode is executed. That is, there is a limit on the number of times that the special prize opening game is continuously executed in the probability variation mode.

  In the time reduction mode, the winning probability of the special symbol lottery is set to a low probability (for example, 999/1000), and the winning probability of the normal symbol lottery is set to a high probability (for example, 1/1). In this ball game machine 1, a so-called time reduction mode is employed. Therefore, the time reduction mode is continued until a predetermined number of times (for example, 100 times) of the fluctuation of the special symbol display means 29 described later in the time reduction mode elapses or until a special symbol lottery is won next. Then, when the number of changes of the special symbol display means 29 passes a predetermined number of times (for example, 100 times) without winning the special symbol lottery, the normal mode is executed after the next time.

  However, in this embodiment, the winning probability of the special symbol lottery in the time reduction mode is low, but is a very high value (999/1000). There is a very high possibility that the next special symbol lottery will be won without passing the predetermined number of times (100 times). For this reason, the time-saving mode may be the one up to the next time instead of the one in which the number of times is reduced, and in this case, the game performance of the ball game machine 1 is hardly affected.

In the normal mode, the winning probability of the special symbol lottery is set to a low probability (999/1000), and the winning probability of the normal symbol lottery is set to a low probability (1/300).
Then, regardless of whether the game state (mode) of the ball game machine 1 is in the probability variation mode, the time reduction mode, or the normal mode, the game state of the ball game machine 1 is in the special prize opening game. However, it has once shifted to the normal mode.

During the probability variation mode or the short time mode, the winning probability of the normal symbol lottery with respect to the entrance of the game ball to the normal symbol start port 18 or the passage of the game ball to the normal symbol start gate 27 is high (1/1). Therefore, special symbol start opening games are frequently executed.
On the other hand, during the normal mode, the winning probability of the normal symbol lottery for the entrance of the game ball to the normal symbol start port 18 or the passage of the game ball to the normal symbol start gate 27 is low (1/300). Special symbol opening opening games are rarely executed. In addition, when the first opening / closing plate 23 is in the closed state, it is impossible to allow a game ball to enter the special symbol start port 21, so that it is almost impossible to enter a game ball into the special symbol start port 21 during the normal mode.

  It is desirable that the winning probability when the special symbol lottery is low is extremely high (that is, close to 1/1). Thereby, the special symbol lottery can be almost won regardless of the gaming state of the ball game machine 1 (whether it is in the probability variation mode, the time reduction mode, or the normal mode). When the special symbol start opening game is executed, in most cases, the special winning opening opening game can be executed (generated) thereafter.

In addition, it is desirable that the winning probability at the time of high probability of the normal symbol lottery is 1/1, but even if it is a value other than 1, it may be a value close to 1. In this case, if the ball enters the normal symbol start port 18 or passes through the normal symbol start gate 27, then the special symbol start port opening game is executed with a very high probability.
In this bullet ball game machine 1, the rotation angle of the handle 10 is normally adjusted, and a game ball is released along the guide rail 14 to the upper left part of the board surface of the game board 2. The game ball that has reached the upper left portion of the board surface of the game board 2 is caused by the obstacle nails planted in the left half (the upper left part, the left part, and the lower left part) of the game board 2 so that the normal design starting port 18 of the game board 2 is reached. It is possible to be guided to the vicinity.

  In addition, the bullet ball game machine 1 can perform a so-called right-handed game (a game in which a game ball is launched toward the right portion of the board surface of the game board 2). Specifically, when the rotation angle of the handle 10 is the maximum angle, the game ball is launched with a very strong momentum. Then, the game ball is released from the upper left portion of the game board 2 along the guide rail 14 diagonally upward to the right. The released game ball passes over the effect display means 15 and reaches the right portion of the board surface of the game board 2.

  The game ball that has reached the right part of the board surface of the game board 2 is led to the vicinity of the normal symbol starting gate 27 on the right part of the game board 2 by the obstacle nails implanted in the upper right part and the right part of the game board 2. It is possible to be removed. In addition, the game ball that has reached the vicinity of the normal symbol start gate 27 is placed near the special symbol start port 21 at the lower part of the game board 2 or the special winning port 22 at the lower part of the game board 2 by the obstacle nail in the vicinity. It is possible to be guided.

In other words, during a right-handed game, the game ball fired on the surface of the game board 2 is led to the vicinity of the normal symbol start gate 27 and at the vicinity of the special symbol start opening 21 or the special prize opening 22 at the lower part of the game board 2. Led to.
In the lower right part of the game board 2, a special symbol display means (symbol display means) 29, a normal symbol hold display means 30, a normal symbol display means (symbol display means) 31, a gaming state, in an area outside the guide rail 14 Display means 32 and round status display means 33 are provided. These display means 29 to 33 are arranged in a line in this order from the lower right portion of the game board 2 toward the lower left direction.

  The special symbol display means 29 is for displaying the result of the special symbol lottery performed for the game ball entering the special symbol start port 21. The special symbol display means 29 is constituted by, for example, one 7-segment display. When a game ball enters the special symbol start port 21, the special symbol of the special symbol display means 29 is alternately switched between "8" and "-" at a high speed. The fluctuation is started and stopped after a predetermined time. At this time, if the result of the special symbol lottery is winning (winning), the special symbol display means 29 displays the symbol “1”, the symbol “2”, the symbol “3” or the symbol “4” as the special symbol. When any one (winning symbol) is stopped and the result of the special symbol lottery is out of order, the symbol “-” (out of symbol) is stopped in the special symbol display means 29.

In the ball game machine 1, the symbol changing operation of the special symbol display means 29 for the game ball entering the special symbol start port 21 is not suspended. Therefore, even if a game ball enters the special symbol start port 21 during the symbol variation of the special symbol display means 29, the symbol variation operation of the special symbol display means 29 for the incoming ball is immediately discarded. It has become.
The normal symbol display means 31 is for displaying the result of the normal symbol lottery performed when the game ball enters the normal symbol start port 18 or the game ball passes through the normal symbol start gate 27. The normal symbol display means 31 is constituted by, for example, one 7-segment display. When a game ball enters the normal symbol start port 18 or passes through the normal symbol start gate 27, the normal symbol on the normal symbol display means 31 is alternately switched between “8” and “−” at high speed. By changing, the normal symbol change of the normal symbol display means 31 is started and stopped after a predetermined time. At this time, when the lottery result of the normal symbol lottery is a win (winning), that is, when it is determined that the first opening / closing plate 23 is opened and closed and the special symbol starting port 21 is opened in a predetermined manner, When the normal symbol “7” (winning symbol) is stopped on the normal symbol display means 31 and the result of the normal symbol lottery is off, the normal symbol “−” (missing symbol) is displayed on the normal symbol display means 31. Stopped.

  During the symbol change of the normal symbol display means 31 (hereinafter, sometimes referred to as “normal symbol change”) and in the normal profit state (during the special symbol start port opening game), a game ball is placed in the normal symbol start port 18. If a game ball passes through the normal symbol start gate 27, the symbol variation operation of the normal symbol display means 31 for the incoming ball can be suspended up to a predetermined number (for example, four times). The symbol changing operation of the held normal symbol display means 31 is executed in accordance with the reserved order after the symbol changing operation of the normal symbol displaying means 31 being executed is completed. The number of symbol fluctuation operations of the held normal symbol display means 31 is displayed on the normal symbol hold display means 30. The normal symbol hold display means 30 is constituted by, for example, a 7-segment display, and can represent the number of symbol change operations held on the screen by numbers.

The game state display means 32 is composed of two lamps arranged adjacent to the normal symbol display means 31. Each lamp is configured to be switched on / off. Depending on the combination of lighting / extinguishing of these lamps, it is displayed whether the gaming state of the ball game machine 1 is the probability variation mode, the time reduction mode, or the normal mode.
The round state display means 33 includes three lamps that are arranged adjacent to the game state display means 32 and can be switched on / off. Depending on the combination of lighting / extinguishing of each lamp, the number of executions of the current special prize opening opening game in a series of jackpot games being executed is displayed.

Among the game balls that fall along the board surface of the game board 2, game balls (out balls) that have not entered any of the normal symbol start port 18, the special symbol start port 21, and the special winning award port 22 are games. It is collected in the machine from the out ball collection port 34 formed in the lower part of the board 2.
FIG. 3 is a block diagram showing an electrical configuration of the ball game machine 1 shown in FIG.
The control circuit of the ball game machine 1 has a main control board 40 and an effect control board 60. The main control board 40 is for controlling the basic operation of the game in the ball game machine 1, and is a CPU (profit state generating means, first notifying means, second notifying means) 41 which is the center of the control. A microcomputer including a random number generator 42 for generating various random numbers, a memory 43 for storing program software, and a counter unit 44 for counting various times. The memory 43 is constituted by a ROM or a RAM, for example. Detection signals are input to the main control board 40 from the normal symbol starting port sensor 20, the normal symbol starting gate sensor 28, the special symbol starting port sensor 24, and the special winning award port sensor 26, respectively. The main control board 40 includes a first opening / closing plate driving member 36 for opening / closing the first opening / closing plate 23, a second opening / closing plate driving member 37 for opening / closing the second opening / closing plate 25, and a special symbol display. Means 29, normal symbol display means 31, normal symbol hold display means 30, gaming state display means 32 and round state display means 33 are connected as control targets.

In the CPU 41 of the main control board 40, a command transmission part 45 for transmitting a command to a command receiving part 65 (included in the CPU 41 of the effect control board 60), which will be described later, of the effect control board 60, performs timing at a predetermined timing A timer 46 and a lottery execution unit 47 for performing various lotteries are included.
The random number generator 42 of the main control board 40 includes a normal symbol per random number generator 48 for generating random numbers used for normal symbol lottery, and a special symbol per random symbol generation for generating random numbers used for special symbol lotteries. And a stop symbol determination lottery random number generation unit 50 that generates a random number used in a stop symbol determination lottery for determining a symbol (stop symbol) to be stopped by the special symbol display means 29.

  The lottery execution unit 47 of the CPU 41 compares the random number values acquired from the normal symbol per random number generation unit 48 of the random number generation unit 42 with a normal symbol per random number table (not shown) stored in the memory 43. Therefore, a normal symbol lottery is performed. Similarly, the lottery execution unit 47 receives the random number values obtained from the random symbol generator 49 for determination of special symbols of the random number generator 42 and the random number generator 50 for stop symbol determination lottery for each special symbol stored in the memory 43. A special symbol lottery and a stop symbol lottery are performed by comparing with a determination random number table (not shown) and a stop symbol determination lottery random table (not shown).

The memory 43 of the main control board 40 includes a normal symbol start storage unit 51, a special symbol start storage unit 52, a special symbol-gaming state correspondence table storage unit 53, a special symbol high probability flag 54, and a general symbol high probability flag 55. It has been.
The normal symbol start storage unit 51 is generated by a normal symbol per-determination random number generation unit 48 that is acquired when a game ball enters the normal symbol start port 18 or passes through the normal symbol start gate 27. Stores the value of the random number for determining per ordinary symbol. The normal symbol start storage unit 51 can store the obtained random numbers for determination per normal symbol for up to five times, one of which is used for executing symbol variation of the normal symbol display means 31. A maximum of four times (upper limit) can be stored for holding the symbol variation of the normal symbol display means 31. When the symbol change of the normal symbol display means 31 is not performed and is not held, and when it is not in the normal profit state, a game ball enters the normal symbol start opening 18, or the normal symbol start gate When the game ball passes at 27, the normal symbol per-determination random number value obtained for the entry or passage is stored in the normal symbol start storage unit 51 for execution. Then, immediately after that, the normal symbol lottery is executed, and the symbol variation of the normal symbol display means 31 is performed according to the result of the executed normal symbol lottery.

  On the other hand, a game ball enters the normal symbol start port 18 or a game to the normal symbol start gate 27 in a state where the normal symbol start determination random number value is already stored in the normal symbol start storage unit 51 for execution. When the ball has passed, the normal symbol per-determining random number value acquired for the incoming or passed ball is stored in the normal symbol start storage unit 51 for holding, and the normal symbol stored for the holding is stored. The number of random numbers for hit determination is counted by a normal symbol hold counter 56 described later (the value of the random numbers for normal symbol determination stored for hold in the normal symbol start storage unit 51 is simply referred to as “normal” hereinafter. Sometimes referred to as “symbol start memory”). The normal symbol per-determining random number value stored in the normal symbol starting storage unit 51 for holding is the symbol variation of the normal symbol display means 31 according to the normal symbol per-determining random number value stored for execution. Is finished, the symbols are sequentially moved up and stored for execution, and the symbol variation of the normal symbol display means 31 corresponding to the values of the reserved random numbers for determining the normal symbols is sequentially executed.

  The special symbol start storage unit 52 stores a result of a special symbol lottery (a random number for determination per special symbol and a random number for special symbol determination lottery) executed for the game ball entering the special symbol start port 21. If the special symbol display means 29 has not been changed and is not on hold and is not in a special profit state, if a game ball enters the special symbol start port 21, The result of the special symbol lottery performed on the ball is stored in the special symbol start storage unit 52 for execution. Immediately thereafter, the symbol change of the special symbol display means 29 according to the stored special symbol lottery result (hereinafter sometimes referred to as “special symbol variation”) is performed.

  The special figure high probability flag 54 is used for storing whether or not the winning probability of the special symbol lottery is high, that is, whether or not the probability fluctuation mode is in progress. ”Is stored, and the value“ 0 ”is stored during the time reduction mode or the normal mode. The common figure high probability flag 55 is for storing whether the winning probability of the normal symbol lottery is high, that is, whether the probability fluctuation mode or the short time mode is in effect. A value of “1” is stored during the medium or short-time mode, and a value of “0” is stored during the normal game mode.

The counter unit 44 includes a normal symbol hold counter 56, a current continuous number counter 57, and an allowable number counter 58. The normal symbol hold counter 56 counts the number of random numbers for determination per normal symbol stored in the normal symbol start storage unit 51 for holding.
Both the current continuous number counter 57 and the allowable number counter 58 are both the probability variation continuous execution number in which the probability variation mode is continuously executed, in other words, the number of times that the special prize opening game is continuously executed in the probability variation mode. Is to count. The current continuous number counter 57 counts the number of times of the probability variation mode that has been continuously executed (occurred) up to the present time (the number of special prize opening games that have been continuously executed up to the present in the probability variation mode). The allowable number counter 58 counts the number of times of the probability variation mode in which execution is allowed continuously thereafter (the number of special prize opening games allowed to be executed continuously in the probability variation mode thereafter). Both are different.

The count values of the counters 56, 57, 58 are stored in a storage area (not shown) provided in the memory 43. In the initial state, the value of the current continuous number counter 57 is set to “0”, and the value of the allowable number counter 58 is set to a predetermined limit number (for example, 30).
On the other hand, the effect control board 60 is for controlling the effect display means 15, the sound generation means 13, and the effect lamp 17, and is a central part of the control CPU 61, a random number generator 62 for generating various random numbers, various data, and the like. Is stored, and a microcomputer including a counter unit 64 that counts various times is provided. The memory 63 is constituted by, for example, a ROM or a RAM. The effect display means 15, the sound generation means 13, and the effect lamp 17 are connected to the effect control board 60 as control targets.

  The CPU 61 of the effect control board 60 includes a command receiving unit (command receiving means) 65 that receives a command from the command transmission unit 45 included in the CPU 41 of the main control board 40 and a display control that controls the display operation of the effect display means 15. 66, a sound control unit 67 that controls the output operation of the sound generating means 13, a lamp control unit 68 that controls the turning on / off of the effect lamp 17, and a lottery execution unit 69 that performs various lotteries.

The random number generator 62 of the effect control board 60 generates a random number used in an effect scenario determination lottery for determining whether to execute an effect related to an effect scenario to be described later and which effect scenario to execute. A random number generator 76 for effect scenario determination lottery to be included is included.
The lottery execution unit 69 of the CPU 61 compares the random number value acquired from the random number generator 76 for effect scenario determination lottery with a random number table for effect scenario determination lottery (not shown) stored in the memory 63, thereby producing the effect scenario. A decision lottery is performed.

In the memory 63 of the effect control board 60, in addition to an effect scenario determination lottery random number table (not shown), an effect pattern data storage unit 70, an effect scenario determination lottery table 71, an opening flag 72, an effect enable flag 73, and a lottery are possible. A flag 74 is provided.
The effect pattern data storage unit 70 stores data of effect patterns constituting the effect scenario. Specifically, display data, sound data, and lamp control data for each effect pattern are stored. During the big hit game, the display control unit 66 controls the display operation of the effect display means 15 based on the display data stored in the effect pattern data storage unit 70. The voice control unit 67 controls the output operation of the voice generation unit 13 based on the voice data stored in the effect pattern data storage unit 70. In the big hit game, the lamp control unit 68 controls the lighting / extinguishing of the effect lamp 17 based on the lamp control data stored in the effect pattern data storage unit 70. The effect scenario determination lottery table 71 is for determining the effect scenario by lottery.

  The opening flag 72 is used for storing that the effect currently being executed by the effect display means 15 is a first effect described later or an effect (early process) described later in the series of effect processes. During the initial production process or during the early stage production described later, the value “1” is stored, and during the production of the later middle stage production (intermediate process) or during the production of the later stage production (end stage processing) described later, “0” is stored. Is stored.

The effect possible flag 73 stores whether or not the execution of the effect in the effect display means 15 is permitted, and a value of “1” in the state where the effect in the effect display means 15 is allowed. Is stored, and a value of “0” is stored in the state where the effect on the effect display means 15 is prohibited.
The lottery possible flag 74 stores whether or not the execution of the production scenario determination lottery by the lottery execution unit 69 is permitted, and a value of “1” in a state where the execution of the production scenario determination lottery is permitted. Is stored, and a value of “0” is stored in a state where execution of the effect scenario determination lottery is prohibited.

The counter unit 64 includes a lottery-capable counter 75 that counts the number of production patterns that need to be executed before the next production scenario determination lottery can be executed. The count value of the lotterable counter 75 is stored in a storage area (not shown) provided in the memory 63.
When the special symbol lottery is won, four types of symbols, “1”, “2”, “3” or “4”, are prepared as special symbols displayed on the special symbol display means 29.

FIG. 4 is a diagram illustrating an example of the special symbol-game state correspondence table.
In the special symbol-game state correspondence table, the type of the determined special symbol and the probability status of the special symbol lottery and the normal symbol lottery after the special winning opening opening game corresponding to each special symbol (each winning probability is shown). Whether it is a high probability or a low probability), that is, the gaming state of the ball game machine 1 after the special prize opening opening game is finished (whether it is a probability variation mode, a time reduction mode or a normal mode) Yes. Then, the probability variation continuous execution count (the number of times the special prize opening game is continuously executed in the probability variation mode) that the probability variation mode continuously executes reaches a predetermined limit number (for example, 30 times). The game state of the ball game machine 1 is different between when the limiter is activated and when the limiter is not activated where the number of times of continuous execution of probability variation has not yet reached the predetermined limit number.

  First, the case where the limiter is not operated will be described. When symbol “2”, symbol “3”, or symbol “4” is selected, the special symbol lottery winning probability and the normal symbol lottery winning probability are both won after the special prize opening game ends. High probability until. That is, the gaming state of the ball game machine 1 after the end of the special prize opening opening game becomes the probability variation mode. When the symbol “1” is selected, the winning probability of the special symbol lottery is low after the special winning opening opening game is finished, but the winning probability of the normal symbol lottery is high. That is, the game state of the ball game machine 1 after the special prize opening opening game ends becomes the time reduction mode. As described above, the time reduction mode is a so-called time reduction mode. That is, it is a time reduction mode that can be continued until the predetermined number of times (for example, 100 times) of the variation of the special symbol display means 29 in the time reduction mode elapses or until the next special symbol lottery is won.

  When the limiter is not operated, in other words, the symbol “2”, the symbol “3”, and the symbol “4” are so-called probability variation symbols, and the symbol “1” is a so-called time-short symbol. In the symbol determination lottery performed simultaneously with the special symbol lottery when the limiter is not operated, the selection probability of the symbol “1” (hereinafter referred to as “selection probability”) is 2%, and the selection probability of the symbol “2” is 50%. The selection probability of the symbol “3” is 40%, and the selection probability of the symbol “4” is 8%.

  Next, the operation when the limiter is activated will be described. When symbol “1”, symbol “3” or symbol “4” is selected, the winning probability of the special symbol lottery is low after the special prize opening game is over, but the winning probability of the normal symbol lottery is high. become. That is, the game state of the ball game machine 1 after the special prize opening opening game ends becomes the time reduction mode. When the symbol “2” is selected, after the special winning opening opening game is finished, the winning probability of the special symbol lottery and the winning probability of the normal symbol lottery are both in a low probability state. That is, the game state of the ball game machine 1 after the special prize opening opening game ends is in the normal mode.

  In this limiter operation, in other words, symbol “1”, symbol “3” and symbol “4” are so-called short-time symbols, and symbol “2” is a so-called normal symbol. In the symbol determination lottery performed simultaneously with the special symbol lottery when the limiter is activated, the selection probability of the symbol “1” is 2%, the selection probability of the symbol “2” is 50%, and the selection probability of the symbol “3” is 40%, and the selection probability of the symbol “4” is 8%. That is, after the special winning opening opening game at the time of the limiter operation, the time reduction mode is executed with a probability of 50%, and the normal mode is executed with a probability of 50%. The selection probability of each symbol in the symbol determination lottery is common when the limiter is activated and when the limiter is not activated.

  The special symbol-gaming state correspondence table defines not only the correspondence between the special symbol and the gaming state, but also the correspondence between the special symbol, the gaming state, and the special prize opening game. In the table shown in FIG. 4, regardless of which special symbol is selected, the special winning opening opening game to be executed is the special winning opening opening game of the common mode (in this embodiment, “0.5 Special prize opening opening game of “2R per second”), it is not necessary for the special winning opening opening game corresponding to each special symbol to be in common. The mode of the special winning opening opening game corresponding to a special symbol may be different from the mode of the special winning port opening game corresponding to another special symbol.

  In the mode in which the normal symbol lottery has a high probability, that is, in the time reduction mode or the probability variation mode, the normal symbol lottery is frequently won. The game characteristics of the ball game machine 1 are that the game state of the ball game machine 1 is kept in the probability variation mode (or either the short-time mode), so that the special symbol start opening game and the special prize opening game are held. Is executed continuously, thereby obtaining a large amount of game balls. As described above, the special symbol start opening game and the special prize opening game are continuously executed for a predetermined period, thereby forming a series of jackpot games advantageous to the player.

  In order to shift from the state in which the ball game machine 1 is in the normal mode to the probability variation mode or the short time mode, first, it is necessary to open the special symbol start port 21 by winning a normal symbol lottery with a low probability of winning. There is. Next, it is necessary to win a special symbol lottery. Since the winning probability of the normal symbol lottery in the normal mode is low (1/300), even if the game ball passes to the normal symbol start gate 27 or the game symbol passes to the normal symbol start port 18 Ordinary symbol lottery is rarely won.

  When the normal symbol lottery is won, a special symbol start opening game is executed. When a game ball enters the special symbol start port 21 during the special symbol start port opening game, a special symbol lottery is executed. Since the winning probability at the low probability of the special symbol lottery is extremely high (999/1000), the special symbol lottery is almost always won. At this time, the symbol (symbol “1”, symbol “2”, symbol “3” or symbol “4”) is stopped and displayed on the special symbol display means 29. Thereafter, a special prize opening game (0.5 seconds × 2R) is executed.

When the symbol displayed on the special symbol display means 29 is a probability variation symbol (symbol “2”, symbol “3” or symbol “4”), the probability variation mode is executed after the special winning opening opening game is ended. .
That is, the normal mode shifts to the probability variation mode. In this ball game machine 1, since the probability that the probability variation symbol is stopped and displayed is 98%, the probability variation mode is almost always executed after the special prize opening game is completed.

  In the probability variation mode, the winning probability of the special symbol lottery is set to be extremely high (1/1), so that the special symbol lottery is won. Then, after the special symbol display means 29 is hit and the symbol (symbol “1”, symbol “2”, symbol “3” or symbol “4”) is stopped and displayed, the special prize opening game (0.5 seconds × 2R) Is executed. If the symbol displayed on the special symbol display means 29 is a probable variation symbol (symbol “2”, symbol “3” or symbol “4”), the probability variation mode is executed again after the special prize opening game is completed. The Since the selection rate of the probability variation symbol is extremely high (98%), the probability variation mode is continuously executed after the transition to the probability variation mode. As a result, once the normal symbol lottery is won, the probability variation mode is continuously executed thereafter.

  In this ball game machine 1, it is easy to enter a game ball into the special symbol start port 21 in the special symbol start port opening game, and the winning probability of the special symbol lottery is extremely high (high probability = 1/1). Therefore, in most cases, the special winning opening opening game is executed (generated) with the execution of the special symbol start opening opening game. And since the probability variation mode with a high winning probability of the normal symbol lottery is continuously executed (even if the short-time mode is executed, the winning probability of the normal symbol lottery is high) is continuous. The start opening game and the special prize opening game are repeatedly executed. Therefore, the special symbol start opening game is continuously executed, and the special winning opening opening game is continuously executed. The special symbol start opening game and the special winning opening opening game are executed independently of each other.

  In this embodiment, a special symbol start-up opening game and a special winning opening opening game that are successively executed are included in a series of jackpot games. That is, whether or not to execute a series of jackpot games is determined by whether or not the normal symbol lottery is won. A series of jackpot games is started by executing the first special symbol opening opening game (after the normal symbol lottery in the normal mode). In this jackpot game, the special symbol start opening game and the special prize opening opening game basically correspond one-to-one.

  A series of jackpot games can be ended by setting the probability variation mode to be executed continuously to a probability variation mode with a limiter. That is, when the probability variation continuous execution number reaches a predetermined limit number (for example, 30 times), the limiter is operated, and after the special prize opening game is finished, the time reduction mode or the normal mode is executed instead of the probability variation mode. . In the ball game machine 1, this series of jackpot games cannot be ended unless the execution of the probability variation mode is forcibly restricted.

  The series of jackpot games includes a plurality of (for example, 30) special symbol start opening games and a plurality of (for example, 30) special prize opening opening games. In this jackpot game, the special symbol start-up opening game and the special prize opening opening game have a one-to-one correspondence. Therefore, the progress status is determined in the probability variation mode, that is, in the probability variation mode. This can be expressed based on the number of special winning opening opening games that are successively executed (how many special winning opening opening games are played).

  For convenience, one game unit period is from the start of the special prize opening game to the start of the next special prize opening game. A series of jackpot games includes a plurality of consecutive game unit periods (for example, 30 sets). The Nth game unit period starts with the start of the Nth special prize opening game, and ends with the start of the next (N + 1) th special prize opening game.

However, the first set of game unit periods starts from the start of normal symbol variation (possible even during normal symbol lottery). Then, after the first special prize opening game, the game ends with the start of the second special prize opening game. Further, the game unit period of the final (for example, 30) set ends at the end of the special prize opening game included in the game unit period.
Since the end timing of a series of jackpot games is defined by the probability variation continuous execution count, the progress status in a series of jackpot games is a probability variation continuous execution count, in other words, a special execution that is continuously executed in the probability variation mode. This can be expressed based on the number of winning opening opening games (the number of special winning opening opening games). And in this series of jackpot games, it is premised that the special symbol start opening game and the special winning opening opening game are basically performed one-on-one, so that the special symbol start opening from the start of the jackpot game The progress status during the jackpot game can be expressed based on the number of times the game is executed (the number of special symbol start opening games), that is, the number of game unit periods (number of sets).

Then, when the time reduction mode is executed after the series of jackpot games is completed, the special prize opening game is executed and the probability variation mode is executed shortly as will be described later. That is, in this case, after a series of jackpot games are completed, a series of jackpot games are generated again.
5A to 5N are schematic views showing the state of the board surface of the game board 2. 5A to 5L of FIG. 5A to FIG. 5N, the illustration of the normal symbol starting port 18 (ordinary symbol starting gate 27), the special symbol starting port 21 and the special winning opening 22 are omitted, and the display contents of the effect display means 15 are omitted. Just showing.

  When the RAM of the ball game machine 1 is cleared, the game state of the ball game machine 1 is in the normal mode. Then, the game by the player is started while the game state of the bullet ball gaming machine 1 is in the normal mode. When the player rotates the handle 10, a game ball is launched from a launch device (not shown) toward the board surface of the game board 2. The game ball launched onto the board surface of the game board 2 falls along the board surface. At this time, for example, a game ball is launched toward the left part (left half) of the board surface of the game board 2.

  Then, as shown in FIG. 5A, when the game ball falling on the board surface of the game board 2 passes through the normal symbol start gate 27, the normal symbol lottery by the main control board 40 is executed. Further, as shown in FIG. 5A, when the game ball falling on the board surface of the game board 2 enters the normal symbol start port 18, the normal symbol lottery by the main control board 40 is executed. Then, in response to the passing of the game ball to the normal symbol start gate 27 or the entry of the game ball to the normal symbol start port 18, the change of the symbol is started in the normal symbol display means 31 and the effect display means 15. Is switched from a standby screen (not shown) to a symbol variation screen (see FIG. 5A). On this symbol variation screen, a plurality of effect symbols are scrolled from top to bottom (high-speed scroll display of effect symbols. (In FIG. 5A, the effect symbols that are scroll-displayed at high speed are not shown. Also, the start of the game unit period of the first set).

  During the normal mode, since the winning probability of the normal symbol lottery is low (1/300), the normal symbol lottery is rarely won. After elapse of a predetermined fluctuation time (for example, 15 seconds), the symbol is stopped and displayed on the normal symbol display means 31. Note that the fluctuation operation of the normal symbol display means 31 based on the passage of the game ball to the normal symbol start gate 27 and the entry of the game ball to the normal symbol start port 18 can be suspended up to “4” in total. Yes.

When the normal symbol lottery is won, that is, when it is determined that a series of jackpot games are executed, the symbol “7” is stopped and displayed on the normal symbol display means 31 as shown in FIG. 5B. Next, on the effect display means 15, a screen for prompting a so-called right-handed game (right-hand suggesting effect screen; see FIG. 5B) is displayed (first suggestion notification) . The screen shown in FIG. 5B is a combination of an image simulating the board surface of the game board 2 in a right-handed game and a message display “Please make a right-handed”.

  In the ball game machine 1 after the start of the jackpot game, after the jackpot game is started (in other words, after winning the normal symbol lottery in the normal mode), the game ball launched on the board of the game board 2 is a special symbol start. It is desirable to gather at the mouth 21. By guiding the game ball to the right part of the board surface of the game board 2, a large number of game balls can pass through the normal symbol start gate 27 and a large number of game balls can enter the special symbol start port 21. Is possible. Therefore, the player performs a right-handed game (a game in which a game ball is launched toward the right portion of the board surface of the game board 2) in accordance with the instruction on the screen shown in FIG. Then, the player continues to perform a right-handed game during a series of jackpot games.

Thereafter, as shown in FIG. 5C, the first opening / closing plate 23 is opened and closed, and the special symbol start opening opening game is executed. At this time, the effect display means 15 displays a screen (see FIG. 5C) that prompts the user to aim at the special symbol start port 21 (second suggestion notification) . The screen shown in FIG. 5C is a combination of an image imitating the board surface of the game board 2 with the special symbol start opening 21 open and a message display “Please insert a ball”.

  When a game ball enters the open special symbol starting port 21, a special symbol lottery is executed. Since the winning probability of the special symbol lottery during the normal mode is extremely high (999/1000), in most cases, the special symbol lottery is won. Further, in response to the game ball entering the special symbol start port 21, the symbol of the special symbol display means 29 starts to fluctuate. Furthermore, 10 prize balls are paid out for one game ball entering the special symbol starting port 21.

  Then, after the predetermined fluctuation time has elapsed, as shown in FIG. 5D, one of the symbols (symbol “1”, symbol “2”, symbol “3” or symbol “4”) stops when the special symbol display means 29 is hit. In addition to the display, a screen for notifying that a series of jackpot games has occurred is displayed on the effect display means 15. On the screen of the effect display means 15 shown in FIG. 5D, a large message “Burning Chain Bonus” is displayed. That is, the first performance is executed. In addition, after the winning symbol is stopped and displayed on the special symbol display means 29, the second opening / closing plate 25 is opened and closed, and a special winning opening opening game is executed (the first special winning opening is released in a series of big hit games). Execution of the game). When the symbol displayed on the special symbol display means 29 is a probability variation symbol (symbol “2”, symbol “3” or symbol “4”), the probability variation mode is executed after the special winning opening opening game is ended. .

Then, as shown in FIG. 5E, when the normal symbol start storage unit 51 has the normal symbol start memory, the normal symbol lottery is executed shortly after the special winning opening opening game is finished, and the normal symbol display means 31 displays the symbol. And the effect display means 15 displays a screen (see FIGS. 5E to 5G) for introducing the appearing character.
That is, when entering a series of jackpot games, that is, winning the first normal symbol lottery, an effect indicating that a jackpot game is being played (see FIGS. 5B to 5G. Also, see FIGS. 5H to 5L to be described later) .) Is displayed in preference to the high-speed scroll display of the effect symbol (see FIG. 5A).

  In the probability variation mode, since the winning probability of the normal symbol lottery is high (1/1), the normal symbol lottery is always won, and as shown in FIG. 5F, the special symbol start opening game is executed. Then, when a game ball enters the special symbol start port 21 during the special symbol start port opening game, the special symbol lottery is executed, and the variation of the symbol in the special symbol display means 29 is started. In the probability variation mode, since the winning probability of the special symbol lottery is high (1/1), the special symbol lottery is always won, and as shown in FIG. Execution of the second special prize opening game in the jackpot game (start of the second set of game unit period).

  From the start of the second set of game unit periods (start of the second special prize opening game) to the end of the fourth set of game unit periods (start of the fifth special prize opening game) (Initial process) is performed on the effect display means 15. The screens included in the early stage effects include the screens shown in FIGS. 5E to 5G and the screen for explaining the game content shown in FIG. 5H. The screen shown in FIG. 5H has a message “The burning chain bonus continues until the fire goes out!”.

  From the start of the 5th game unit period (start of the 5th special prize opening game) to the end of the 29th game unit period (start of the 30th special game opening game), effect display means The middle stage effect (middle stage process) is displayed at 15. Examples of the screens included in the middle stage effect include the screens shown in FIGS. 5I, 5J, and 5K. In the middle stage production of the ball game machine 1, a plurality of production scenarios with motifs of catches from the Edo period are prepared, and the production patterns included in the production scenario determined by the production scenario decision lottery are displayed.

  Then, when the 30th set of game unit periods is started (start of the 30th special prize opening game), the effect display means 15 displays the effect of the end game (end game process). This final stage production includes a screen (not shown) for notifying the end of a series of jackpot games. Then, the screen shown in FIG. 5L is displayed at the final part of the special prize opening opening game. The screen shown in FIG. 5L has a message indicating the number of acquired game balls, “Burning chain bonus completed! Acquired xxxxxx × both!”.

  Then, after the end of the 30th game unit period (after the end of the 30th special prize opening game), that is, after the end of a series of jackpot games, the short-time mode is executed with a probability of 50%, and a probability of 50% In normal mode. When the short-time mode is executed after a series of jackpot games, the winning probability of the normal symbol lottery in the short-time mode is high (1/1), so the execution of the special symbol start opening game is started. The After the jackpot game ends, a series of jackpot games are executed again with a probability of 50%. This subsequent jackpot game is referred to as “revival jackpot game”. When the short-time mode is executed after the series of jackpot games is completed, a screen for notifying the revival jackpot game shown in FIG. 5M is displayed on the effect display means 15.

  Thereafter, the special symbol start opening game is started, and the special symbol lottery is executed based on the game ball entering the special symbol start port 21 during the special symbol start opening game. Then, when the special symbol lottery is won, a screen indicating that the revival jackpot game shown in FIG. On the screen shown in FIG. 5N, a message “continuation of burning” is displayed. Thereafter, the first set of game unit periods is started. Then, in the second to fourth sets of game unit periods, the effects of the early stage effects (screens shown in FIGS. 5E to 5G) are displayed on the effect display means 15. Further, during the game unit period of the fifth to 29th sets, the middle stage effect (the screens shown in FIGS. 5I, 5J and 5K) is displayed on the effect display means 15. Further, in the 30th game unit period, the final stage effect (the screen shown in FIG. 5L) is displayed on the effect display means 15.

FIG. 6 is a flowchart showing the flow of the ball entry process performed by the main control board 40 for the passage of the game ball to the normal symbol start gate 27 or the entrance of the game ball to the normal symbol start port 18.
During the game by the bullet ball game machine 1, the main control board 40 monitors whether or not the game ball has passed through the normal symbol start gate 27 based on the presence / absence of an input signal from the normal symbol start gate sensor 28. (Step S1). Further, the main control board 40 monitors whether or not a game ball has entered the normal symbol starting port 18 based on the presence / absence of an input signal from the normal symbol starting port sensor 20 (step S2).

  When a game ball passes through the normal symbol start gate 27 or a game ball enters the normal symbol start port 18 (YES in step S1 or YES in step S2), the main control board 40 reads the normal symbol hold counter. 56 count values are confirmed (step S3), and if the count value (the number of holdings) has not reached “4” (NO in step S3), the normal symbol per random number generator 48 determines the normal symbol per symbol. A random number is acquired (step S4). The main control board 40 stores the random number for normal symbol determination in the normal symbol start storage unit 51 (step S5), and increments (+1) the count value of the normal symbol hold counter 56 (step S6). The process for entering the symbol starting port 18 or passing to the normal symbol starting gate 27 is terminated.

On the other hand, if the count value of the normal symbol holding counter 56 is “4” (YES in step S3), the normal symbol starting gate 18 or the normal symbol starting gate is stored without storing the random number for determining the normal symbol. The processing for the passage to 27 is terminated.
FIG. 7 is a flowchart showing the game flow after the ball entry process shown in FIG.
When the random number for determining the normal symbol is stored in the normal symbol start storage unit 51 (YES in step S11), the main control board 40 confirms the value of the normal symbol high probability flag 55 (step S12), A symbol lottery determination is performed (steps S13 and S15).

  When the gaming state of the ball game machine 1 is in the probability variation mode or in the short-time mode, that is, when a value of “1” is stored in the usual high probability flag 55 (YES in step S12), The main control board 40 makes a normal symbol hit determination using a high probability (1/1) determination criterion (step S13). After the normal symbol lottery, the main control board 40 sets the symbol variation time of the normal symbol display means 31 to, for example, 0.6 seconds (step S14), and starts the symbol variation of the normal symbol display means 31 (step S14). S17). Further, the main control board 40 gives a control command to the effect control board 60. In response to this control command, the effect control board 60 starts the symbol variation of the effect display means 15. Specifically, on the symbol variation screen (see FIG. 5A), a plurality of effect symbols are scroll-displayed from top to bottom at high speed (in FIG. 5A, effect symbols that are scroll-displayed at high speed are not shown).

  On the other hand, when the gaming state of the ball game machine 1 is in the normal mode, that is, when a value of “0” is stored in the usual figure high probability flag 55 (NO in step S12), the main control board In step S15, normal symbol per unit determination is performed using a determination criterion of low probability (1/300). After the normal symbol lottery, the main control board 40 sets the symbol variation time of the normal symbol display means 31 to, for example, 15 seconds (step S16), and starts the symbol variation of the normal symbol display means 31 (step S17). . Further, the main control board 40 gives a control command to the effect control board 60. In response to this control command, the effect control board 60 starts the symbol variation of the effect display means 15. Specifically, on the symbol variation screen (see FIG. 5A), a plurality of effect symbols are scroll-displayed from top to bottom at high speed (in FIG. 5A, effect symbols that are scroll-displayed at high speed are not shown).

After the lapse of the variation time set in step S14 or step S16 (YES in step S18), the symbol variation of the normal symbol display means 31 is stopped and the stopped symbol is displayed (step S19). In addition, when the symbol variation of the normal symbol display means 31 stops, the effect display means 15 stops the effect symbols.
If the result of the normal symbol lottery is out of place (NO in step S20), the out-of-order symbol “-” is displayed as the stop symbol, and then the main control board 40 enters the normal symbol start port 18 into the game ball. Alternatively, the process for passing the game ball to the normal symbol start gate 27 is terminated. In this case, the effect control board 60 causes the effect display unit 15 to stop display the combination of the effect symbols that are out of alignment.

  On the other hand, when the normal symbol lottery is won (YES in step S20), the main control board 40 displays the winning symbol “7” as the stop symbol and notifies the player that the normal symbol lottery has been won. In this case, the effect control board 60 stops and displays the winning effect combination on the effect display means 15. Thereafter, the main control board 40 opens the first opening / closing plate 23 to open the special symbol start port 21 for 3.0 seconds, and repeats the opening of the special symbol start port 21 twice (special symbol start port). Open game, step S21). Thereafter, the processing for entering the game ball into the normal symbol start port 18 or passing the game ball to the normal symbol start gate 27 is finished.

  In the special symbol start opening game, the opening period of the special symbol start opening 21 depends on whether the winning probability of the normal symbol lottery is high, that is, whether it is in the probability variation mode or the short time mode. It may be different. Further, for example, during the normal mode, the opening period of the special symbol start opening 21 in the special symbol start opening opening game may be set shorter than in the probability variation mode or the time reduction mode.

FIG. 8A and FIG. 8B are flowcharts showing the game flow when a game ball enters the special symbol starting port 21.
During a game by the ball game machine 1, the main control board 40 monitors whether or not a game ball has entered the special symbol start port 21 based on the presence or absence of an input signal from the special symbol start port sensor 24. (Step S31).

  When a game ball enters the special symbol start port 21 (YES in step S31), the main control board 40 does not store a random number in the special symbol start storage unit 52 (NO in step S32). A random number for special symbol determination is acquired from the random number generator 49 for determination of hit (step S33). Further, the main control board 40 obtains a stop symbol determination lottery random number from the stop symbol determination lottery random number generator 50 (step S34). After that, the main control board 40 stores (stores) the special symbol per-determination random number and the stop symbol determination lottery random number in the special symbol start storage unit 52 (step S35).

Thereafter, after confirming the value of the special figure high probability flag 54 (step S36), the main control board 40 performs a special symbol lottery determination and a stop symbol type determination (steps S37, S38, S39). .
When in the probability variation mode, that is, when a value of “1” is stored in the special figure high probability flag 54 (YES in step S36), the main control board 40 has a high probability (1/1). The special symbol hit determination is performed using the determination criterion (step S37).

On the other hand, when in the time reduction mode or the normal mode, that is, when the value of “0” is stored in the special figure high probability flag 54 (NO in step S36), the main control board 40 has a low probability. A special symbol hit determination is performed using the (999/1000) determination criterion (step S38).
In the determination of the type of the stopped symbol in step S39, the main control board 40 determines the special symbol random number acquired in the processing in step S34 and the symbol selection ratio described in the special symbol-game state correspondence table shown in FIG. Based on the above, one special symbol is selected from four types of special symbols (symbol “1”, symbol “2”, symbol “3” or symbol “4”). In this case, the selection probability of the symbol “1” is 2%, and the selection probability of the symbol “2” is 50%. The selection probability of the symbol “3” is 40%, and the selection probability of the symbol “4” is 8%.

  Then, the main control board 40 starts the symbol variation of the special symbol display means 29 (step S40). On the special symbol display means 29, a stop symbol (special symbol) is stopped and displayed after a predetermined fluctuation time has elapsed (YES in step S41). When the result of the special symbol lottery is a win, the special symbol display means 29 displays one of the symbols “1”, “2”, “3” or “4” (step S42). If the lottery result is out of place, the special symbol display means 29 displays the symbol “-” (out of symbol) (step S42).

  If the result of the special symbol lottery is a win (YES in step S43), the main control board 40 (the command transmission unit 45) starts the special winning opening opening interval with respect to the effect control board 60 (the command reception unit 65). A command (F0 ?? H), limiter designation 1 command (F6 ?? H. Allowable number designation command) and limiter designation 2 command (F7 ??? H. Current continuous number designation command) are transmitted (steps S44, S45). Further, the main control board 40 executes a special winning opening opening game (step S46).

  In the special winning opening opening game in step S46, the special winning opening until a predetermined time (for example, 0.5 seconds) elapses or until a predetermined number (for example, 10 balls) of gaming balls enter the special winning opening 22. An operation such as opening 22 is defined as one round, and such an operation is performed for a small number of rounds (for example, 2 rounds) with an interval of a predetermined time (for example, 1 second) (special prize opening opening game) .

After the end of the special winning opening opening game, the game state of the ball game machine 1 is a special symbol-game state correspondence table and a stop symbol (stopped on the special symbol display means 29 at the start of the special winning opening opening game ( It is determined based on the type of special symbol.
When the probability variation mode is executed after the end of the special prize opening game (YES in step S47), that is, when the limiter is not activated and the stop symbol for starting the special prize opening game is “2”. When the symbol is “3” or “4”, the special figure high probability flag 54 is set to “1”, and the common figure high probability flag 55 is set to “1”. Then, the value of the current continuous number counter 57 is incremented (+1), and the value of the allowable number counter 58 is decremented (−1) (step S49).

  In addition, when the short time mode is executed after the special winning opening opening game is finished (NO in step S47 and YES in step S48), that is, the stop pattern for starting the special winning opening opening game is the symbol “1”. If there is, or if the limiter is activated and the stop symbol for starting the special prize opening game is the symbol “3” or the symbol “4”, the special symbol high probability flag 54 is set to “0”. The usual high probability flag 55 is set to “1”. Then, the value of the current continuous number counter 57 is reset to “0” and the value of the allowable number counter 58 is reset to the original value (for example, “30”) (step S50).

  Further, when the normal mode is executed after the special winning opening opening game is finished (NO in step S47 and step S48), that is, when the limiter is activated and the special winning opening opening game starts, the stop pattern is “2”. ", The special figure high probability flag 54 is set to" 0 "and the normal figure high probability flag 55 is set to" 0 ". Then, the value of the current continuous number counter 57 is reset to “0”, and the value of the allowable number counter 58 is reset to the original value (for example, “30”) (step S51).

Thereafter, the main control board 40 ends the process for entering the game ball into the special symbol start port 21.
FIG. 9 is a diagram for explaining a control command transmitted from the main control board 40 (the command transmission unit 45) to the effect control board 60 (the command reception unit 65) at the start of the special prize opening opening game.

  The control command has a 2-byte configuration including 1-byte mode data and 1-byte event data. In each control command, the mode data and event data are transmitted and received individually in succession. The mode data is for designating the outline portion of the production content, and has a hexadecimal 2-digit value. The event data is for designating a specific part of the production content, and has a value of 01 to 7F (2 hexadecimal digits). Also, the letter “H” added to the end of each data (mode data, event data) shown in FIG. 9 is a subscript, and is meant to mean a hexadecimal number.

Of the two-digit values of the mode data of the ball game machine 1, the first one-digit value is set to “A”, “B”, “E” or “F” (FIG. (Only those where the previous one digit value is “F” out of the two digit value of the data). Therefore, the value of the most significant bit when the mode data is represented by a bit string is “0”. Further, the first one digit value of the two digits of the event data is set to any one of “0” to “7”. Therefore, the value of the most significant bit when the mode data is represented by a bit string is “0”. Therefore, the presentation control board 60 only determines the most significant bit of the control command (data) received from the main control board 40, and determines whether the control command (data) is mode data or event data. Can be determined.

  At the start of the special prize opening game, three commands, a special prize opening opening interval command, a limiter designation 1 command, and a limiter designation 2 command, are transmitted from the main control board 40 to the effect control board 60 as control commands. . All mode data of the special winning opening opening interval command has a value of “F0” (H of “F0H” is a subscript; the same applies hereinafter). All the mode data of the limiter designation 1 command have a value of “F6”. All the mode data of the limiter designation 2 command have a value of “F7”.

  The special prize opening opening interval command is a command for instructing the production control board 60 to execute production control corresponding to the special prize opening opening game. The event data of the special prize opening opening interval command is the type of special symbol (design “1”, symbol “2”, symbol “3”, or symbol “4”) when the special prize opening opening game is executed. )). Also, the event data has different values depending on the gaming state of the ball game machine 1 before the special winning opening opening game is executed (that is, whether it is the probability variation mode, the short time mode, or the normal mode). have.

  Specifically, the last one digit value of the event data of the special prize opening opening interval command (that is, the portion corresponding to the lower 4 bits of the event data) is the special prize opening opening game. It corresponds to the type of special symbol at the time of execution. When the special symbol is the symbol “1”, the last one digit value of the two digits of the event data is “1”, and when the special symbol is the symbol “2”, the event data 2 Of the digit values, the last one digit value is “2”. When the special symbol is symbol “3”, the last one digit of the two digits of the event data is “3”, and when the special symbol is “4”, the event data 2 The digit value after the digit value is “4”.

  In addition, the value of the previous one digit (that is, the portion corresponding to the upper 4 bits of the event data) of the two-digit value of the event data of the special prize opening opening interval command is executed. This corresponds to the gaming state of the bullet ball game machine 1 before the game. When the game state of the ball game machine 1 before the special prize opening game is in the normal mode, that is, when the winning probability of the normal symbol lottery is low and the winning probability of the special symbol lottery is low, Of the two-digit value of data, the previous one-digit value is “0”. When the game state of the ball game machine 1 before the special prize opening game is in the short-time mode, that is, when the winning probability of the normal symbol lottery is high and the winning probability of the special symbol lottery is low, Of the two-digit values of the data, the previous one-digit value is “1”. When the gaming state of the ball game machine 1 before the special prize opening game is in the probability variation mode, that is, when the winning probability of the normal symbol lottery is high and the winning probability of the special symbol lottery is high, Among the two-digit values of the event data, the previous one-digit value is either “2” or “3”. In this case, “2” is when the limiter is not operating, and “3” is when the limiter is operating.

  The limiter designation 1 command is a value of the allowable number counter 58, that is, the number of probability variation modes that are continuously allowed to be executed thereafter (a special prize opening game that is allowed to be executed continuously thereafter in the probability variation mode). ) Is notified to the effect control board 60. The event data value of the limiter designation 1 command indicates the allowable number of times of the probability variation mode.

  The limiter designation 2 command indicates the number of times the probability variation mode has been continuously executed by the current continuous number counter 57 up to the present time (the number of special winning opening opening games that have been continuously executed in the probability variation mode). The notification control board 60 is notified. The event data value of the limiter designation 2 command indicates the number of times of the probability variation mode executed continuously.

  FIG. 10 and FIG. 11 are time charts for explaining the control by the main control board 40 from the start of symbol change in the normal symbol display means 31 to the end of the special prize opening opening game. FIG. 10 shows a case where a special symbol start opening game and a special winning opening release game are each in a series of jackpot games, and FIG. 11 shows a special symbol start opening game and a special winning opening in a series of jackpot games. The case where the open game is the second or later is shown.

During the normal mode, the variation time of the normal symbol is extremely long (for example, 15 seconds), so that the result of the normal symbol (starting memory) is difficult to digest.
Referring to FIG. 10A, when an input signal from the normal symbol start gate sensor 28 or the normal symbol start port sensor 20 is detected during the normal mode, the CPU 41 of the main control board 40 detects the normal symbol display means. 31 symbol variations are started (common symbol variations shown in FIG. 10A). After the symbol variation of the normal symbol display means 31 is executed for a predetermined variation time (for example, 15 seconds), the predetermined stop symbol (ordinary symbol) is stopped and displayed for, for example, 0.5 seconds (shown in FIG. 10A). Common figure). As a result, the normal symbol is fixedly displayed. Thereafter, a special symbol start opening opening game (special drawing start opening shown in FIG. 10 (a)) is started with a public power release start interval (for example, 5.0 seconds) interposed therebetween.

  During the period of the general electric power release opening (for example, 5.0 seconds), the effect display means 15 displays a screen shown in FIG. 5B (a screen that encourages a so-called right-handed game (right-hand suggesting effect screen)). Specifically, after the normal symbol is confirmed and displayed on the normal symbol display means 31, the main symbol stop command BE01H (not shown in FIG. 9) is transmitted from the main control board 40 to the effect control board 60. The effect control board 60 displays the screen shown in FIG. 5B on the effect display means 15 when receiving the usual figure stop command. A special symbol start opening opening game is started after the end of the public power release start interval (for example, 5.0 seconds).

In the special symbol start opening game, for example, the special symbol start opening 21 is opened twice, for example, with an interval of 1.0 second in between. From the start of the first opening (first half, for example, 3.0 seconds) in the special symbol start opening game, the end of the second opening (second half, for example, 3.0 seconds) at the special symbol starting opening 21. The period until is 7.0 seconds including an interval of 1, 0 seconds. The opening time of the special symbol start port 21 in the special symbol start port opening game is 6.0 seconds in total. In a special symbol opening opening game, it is easy to enter a game ball. When a game ball enters the special symbol start port 21, an input signal from the special symbol start port sensor 24 is detected.

  After the elapse time of the special symbol starting port 21, the CPU 41 of the main control board 40 controls the first opening / closing plate 23 to close the special symbol starting port 21. After the special symbol start port 21 is closed by the first opening / closing plate 23, the main control board 40 waits, for example, for 2.0 seconds to confirm the discharge. As described above, the special symbol start port sensor 24 is arranged at a predetermined distance from the special symbol start port 21. Therefore, the game ball that has entered the special symbol start port 21 is waited for a predetermined discharge confirmation period (for example, 2.0 seconds) so that the special symbol start port sensor 24 can reliably detect the game ball. .

Then, after the elapse of a predetermined discharge confirmation period, for example, after waiting for the elapse of a 5.0 second normal power release end interval, the CPU 41 of the main control board 40 performs the normal symbol variation operation based on the start memory of the next normal symbol. The normal symbol display means 31 is started (see FIG. 11A).
On the other hand, referring to FIG. 10B, when an input signal from the special symbol start port sensor 24 is detected during the special symbol start port opening game, the main control board 40 changes the symbol variation of the special symbol display means 29. Is started (figure variation shown in FIG. 10B). After the symbol variation of the special symbol display means 29 is executed for a predetermined variation time (for example, 0.6 seconds), a predetermined stop symbol (special symbol) is stopped and displayed for 0.5 seconds (FIG. 10B). Special figure shown). As a result, the special symbol is confirmed and displayed. Thereafter, a special prize opening game is executed.

  Specifically, after the special symbol is confirmed and displayed, after the elapse of a predetermined special winning opening opening start interval (for example, 1.0 second), the second opening / closing plate 25 is driven to open the special winning opening 22. The In the special prize opening game, the operation of opening the special prize opening 22 for 0.5 seconds is defined as one round, and for example, two rounds are performed with an interval of 2.0 seconds in between. And after completion | finish of each round, ie, after the special winning opening 22 is obstruct | occluded by the 2nd opening-and-closing board 25, the main control board 40 waits for 2.0 second, for example for discharge | emission confirmation. As described above, the special prize opening sensor 26 is disposed at a predetermined distance from the special prize opening 22 so that the game balls that have entered the special prize opening 22 can be reliably detected by the special prize opening sensor 26. This is to wait for a predetermined discharge confirmation period (for example, 2.0 seconds). After the end of the discharge confirmation period corresponding to the later round, the special winning opening release game ends after waiting for the elapse of the special winning opening release end interval (open end interval, 0.5 seconds). After the first special payout opening game is completed, the probability variation mode or the time reduction mode is selectively executed (in most cases, the probability variation mode).

  In this embodiment, the interval period between the opening and closing of the special winning opening 22 before and after the special winning opening 22 in the special winning opening opening game coincides with the above discharge confirmation period (the discharge confirmation period after the first round). That is, the period required for the special prize opening opening game includes the special prize opening opening start interval (1.0 second), the special opening 22 twice opening time (each 0.5 seconds), and the special winning opening 22 opening. Is a period (a total of 6.5 seconds) obtained by adding a discharge confirmation period (each 2.0 seconds) and a special winning opening opening end interval (0.5 seconds).

With reference to Fig.11 (a), the 2nd special symbol start opening game is demonstrated. When the normal symbol start storage unit 51 has the normal symbol start memory, the CPU 41 of the main control board 40 causes the normal symbol display means 31 to start the normal symbol changing operation based on the result of the normal symbol lottery. At this time, since the state of the ball game machine 1 is the probability variation mode or the short time mode (probability variation mode in most cases), the symbol variation of the normal symbol display means 31 is executed for a short variation time (for example, 0.6 seconds). After being performed (the normal pattern variation shown in FIG. 11A), a predetermined stop symbol (ordinary symbol) is stopped and displayed for 0.5 seconds, for example. As a result, the normal symbol is fixedly displayed (the universal symbol shown in FIG. 11A). Thereafter, for example, a special symbol start opening opening game is executed with a public power release start interval of 0.1 seconds (for example, the special figure start opening shown in FIG. 11A). The second and subsequent special symbol start opening games are similar to the first special symbol start opening game described above. After the elapse of a predetermined discharge confirmation period (for example, 2.0 seconds) in the special symbol start opening game, the CPU 41 of the main control board 40 waits for the elapse of the normal power release end interval, The normal symbol changing operation based on the start memory (the result of the normal symbol lottery) is started by the normal symbol display means 31.

A plurality of types (for example, three types, for example, 0.5 seconds, 1.0 seconds, or 1.5 seconds) are prepared for the interval of the end of opening of the public power in the second and subsequent special symbol opening opening games. Specifically, the main control board 40 selectively determines one of the three types as the normal power release end interval in relation to each special symbol start opening game. Then, the main control board 40 executes the selected utility power release end interval. For this reason, the period of the opening period for the opening of the public train differs for each special symbol opening opening game. It should be noted that a plurality of types of normal symbol hit symbols may be provided, and the period of the utility power release end interval may be selected according to the type of hit symbols.

  In the second and subsequent special symbol start-up opening games, when an input signal from the special symbol start-up sensor 24 is detected during the special symbol start-up opening game, as shown in FIG. The board 40 starts the symbol variation of the special symbol display means 29. After the symbol variation of the special symbol display means 29 is executed for a predetermined variation time (for example, 0.6 seconds) (the special symbol variation shown in FIG. 11B), the predetermined stop symbol (special symbol) is 0.5. The display is stopped for 2 seconds. Thereby, the special symbol is confirmed and displayed (special symbol confirmation shown in FIG. 11B). Thereafter, a special prize opening game is executed. This special prize opening game is the same as the first special prize opening game. That is, the period required for the special prize opening opening game includes the special prize opening opening start interval (1.0 second), the special opening 22 twice opening time (each 0.5 seconds), and the special winning opening 22 opening. Is a period (a total of 6.5 seconds) obtained by adding a discharge confirmation period (each 2.0 seconds) and a special winning opening opening end interval (0.5 seconds).

As described above, the special symbol start port 21 is formed in a size that allows a plurality (3 to 4) of game balls to enter simultaneously. Therefore, in each special symbol start opening game, a game ball enters the special symbol start port 21 shortly after the start of the special symbol start opening game.
However, at the start of the first special symbol start-up opening game, it is possible that the game ball does not flow to the special symbol start-up port 21 since the right-handed game has started. In this case, it is conceivable that the game ball does not enter the special symbol start port 21 even after a certain period of time has elapsed after the start of the special symbol start port opening game.

  In the bullet ball game machine 1, the period for the opening of the second special symbol start-up opening game is set to 0.1 seconds, whereas the first special symbol starting-open opening game is set for the first time. The period of the opening start interval is set to 5.0 seconds. Therefore, the start timing of the special symbol start port opening game can be delayed until the flow to the special symbol start port 21 is completed. Then, immediately after the start of the special symbol start port opening game, the game ball can enter the special symbol start port 21.

  In the first special winning opening opening game, the right-hand suggesting effect screen (see FIG. 5B) is displayed on the effect display means 15 during the opening period of the electric train opening (5.0 seconds) (see FIG. 10B). Right-hand suggestion period shown in a)). Therefore, the player plays a right-handed game according to the right-handed instruction. Then, the game balls flowing down the game board 2 can be collected around the special symbol start opening 21 when the general electric release start interval (5.0 seconds) has elapsed, that is, when the special symbol start opening 21 starts to open. it can.

  In the series of jackpot games of the ball game machine 1, the special symbol start opening game and the special prize opening game are continuously executed as described above. In this series of jackpot games, When the normal symbol lottery is executed during the special winning opening game, the continuity of the special symbol opening opening game in a series of jackpot games is lost. This will be specifically described below.

  As described above, regardless of whether the game state of the ball game machine 1 is in the probability variation mode, the short-time mode, or the normal mode (the special figure high probability flag 54 or the normal figure high probability flag 55 is set to “1”). ”Regardless of whether or not“ ”is set), during the special prize opening game, the game state of the ball game machine 1 is in the normal mode. Therefore, if the special winning opening opening game ends and there is a normal symbol starting memory during the special winning opening opening game (from the start of the special winning opening opening interval until the elapse of the special winning opening release interval), the starting memory is stored. The normal symbol lottery corresponding to is executed with a winning probability with a low probability (1/300).

When the winning probability of the normal symbol lottery is low (1/300), the fluctuation operation of the normal symbol corresponding to the normal symbol lottery has a long variation time (for example, 15 seconds). When the symbol variation operation includes reach or the like, the regular symbol variation time becomes longer.
In the ball ball game machine 1, the special symbol start in the special symbol start opening opening game is usually started after the opening of the special symbol start opening 21 in the special symbol start opening opening game (the second and subsequent special symbol start opening opening game). The period until the opening of the mouth 21 is started is a discharge confirmation period (for example, 2.0 seconds), a normal power open end interval (for example, 0.5 seconds, 1.0 seconds, or 1.5 seconds), a normal symbol Period (for example, 0.6 seconds), normal symbol confirmation time (for example, 0.5 seconds), and general electric power release opening interval (for example, 0.1 seconds) (for example, a total of 3.7 seconds) (Total 4.2 seconds or total 4.7 seconds).

  On the other hand, when the normal symbol lottery is executed with a low probability (1/300), the special symbol in the next special symbol start-up opening game from the end of the opening of the special symbol start-up port 21 in the special symbol start-up opening game. During this period (for example, a total of 3.7 seconds, a total of 4.2 seconds, or a total of 4.7 seconds), the period until the start of the opening of the start port 21 is changed to a normal symbol variation time (for example, 15 seconds) and This is a period (for example, a total of 23.0 seconds, a total of 23.5 seconds, or a total of 24.0 seconds) in which the public power release start interval (5.0 seconds) is replaced.

Therefore, if the normal symbol lottery is executed during the special winning opening game, a long interval occurs between the special symbol starting games, and the continuity of the special symbol starting game in the series of jackpot games is lost. It will be. In the ball game machine 1, the following measures are taken so that the normal symbol lottery is not drawn with a low probability during the jackpot game.
Assume that during the special winning opening opening game corresponding to a certain special symbol starting opening game, the normal symbol starts to fluctuate prior to the special symbol starting opening opening game next to the special symbol starting opening game.

If the second special symbol opening opening game is completed before the first special winning opening opening game is finished, the normal symbol lottery is executed during the special winning opening opening game. There is a risk of being drawn with a low probability (for example, 1/300).
In other words, in order to prevent the normal symbol lottery from being executed with a low probability (1/300), the end timing of the special symbol start port opening game in each special symbol start port opening game (hereinafter referred to as “special symbol start port opening end timing”). In other words, the end timing of the special power start opening game is the end timing of the special winning opening opening game corresponding to the special symbol start opening opening game (hereinafter referred to as “special winning opening opening end timing”). It is desirable that it is always slower than the time when the mouth opening end interval elapses.

As a technique of always delaying the special symbol start opening release end timing from the special winning opening opening end timing, in the special symbol start opening opening game, the special symbol start opening opening game is ended from the start of opening the special symbol starting opening 21 (ie It is conceivable to set the period until the electric opening end interval elapses) to be significantly longer than the entire period of the special prize opening opening game.
However, since there is a restriction that the opening period of the special symbol start opening 21 in one special symbol start opening opening game must be set within 6.0 seconds in total, the period of the special symbol start opening opening game is limited. It cannot be set for too long. On the other hand, in the special prize opening game, it is necessary to execute a plurality of rounds of the special prize opening game during one special prize opening game, and the game balls to the special prize opening 22 in each round are played. A discharge confirmation period (for example, 2.0 seconds) is provided for the incoming ball. Therefore, it is not possible to set the special winning opening opening game period too short. Further, as described above, the special winning opening opening game is started based on the entering of the game ball into the special symbol starting port 21 during the corresponding special symbol starting port opening game. It is difficult to assume the timing at which a game ball flowing down the game board 2 enters the special symbol start port 21.

  In the ball game machine 1, as shown in FIG. 11 (a), in relation to the second and subsequent special symbol start opening games, the special symbol start port 21 after the first opening of the special symbol start port 21 A period (for example, 9.5 seconds, 10.0 seconds, or 10.5 seconds) is an assumed entry period of the game ball to the special symbol start opening 21 in the second and subsequent special symbol start opening games (FIG. 11 (a ) Before the special winning opening opening game (for example, a total of 6.5 seconds), special symbol change time (for example, 0.6 seconds), and special symbol confirmation time (for example, 0.5 seconds) ) Are set to be longer than a period (for example, 9.1 seconds).

Therefore, in most cases, the special symbol start opening opening end timing can be made later than the special winning opening opening end timing, so that before the end of the general electricity opening end interval in the next special symbol starting opening opening game. The special prize opening opening game corresponding to the previous special symbol start opening opening game can be ended.
The “assumed entry period (pre-addition period)” refers to a period sufficient for one game ball to enter the special symbol start opening 21 from the start of the special symbol start opening opening game. Therefore, in the second and subsequent special symbol start-up opening games, the game ball enters the special symbol start-up port 21 soon after the opening (for example, within 1.5 seconds).

  The period of the public power release start interval in the second and subsequent special symbol opening opening games is set to 0.1 seconds, for example. In addition, as a normal power release end interval in the second and subsequent special symbol opening opening games, for example, a normal power release end interval of 0.5 seconds, 1.0 second, or 1.5 seconds is prepared. Therefore, the period of the entire special symbol opening opening game is as follows: the opening interval of the electric train opening (for example, 0.1 seconds), the opening time of the special symbol starting port 21 twice (for example, 3.0 seconds each), and the special symbol starting port. 21 between two opening times (for example, 1.0 second), a discharge confirmation period provided for each opening of the special symbol start port 21 (for example, each 2.0 seconds), and a normal power supply opening end interval This is a period (for example, 9.6 seconds, 10.1 seconds, or 10.6 seconds) added (for example, 0.5 seconds, 1.0 seconds, or 1.5 seconds). The period after the first opening of the special symbol start opening 21 in the special symbol start opening opening game is a period obtained by subtracting the general electric release opening interval (for example, 0.1 second) from the entire period of the special symbol start opening opening game. (For example, 9.5 seconds, 10.0 seconds, or 10.5 seconds).

On the other hand, the total period of the second and subsequent special prize opening games is, for example, a total of 6.5 seconds as described above.
In addition, as described above, in the second and subsequent special symbol opening opening games, there are a plurality of types (for example, three types, for example, 0.5 seconds, 1.0 seconds, or 1.5 seconds) of public power release end intervals having different periods. Seconds).

  If the period of the opening period of the regular electric train is constant, the period from the end of the opening and closing movement of the special symbol starting port 21 to the start of the opening and closing operation of the special symbol starting port 21 in the next special symbol starting port opening game Becomes constant. Therefore, a player who has played with the ball game machine 1 several times can know the time from the end of opening the special symbol start port 21 to the opening of the next special symbol start port 21. Then, it becomes possible to launch the game ball at such a launch timing that the launched game ball reaches the special symbol start port 21 when the special symbol start port 21 is opened.

  The handle 10 is provided with a projecting stop button (not shown) that can be pushed in. By pushing this firing stop button, a game ball is not fired from a launching device (not shown) regardless of the rotational operation of the handle 10. The player presses the launch stop button to stop the launch of the game ball, and the launch timing such that the game ball reaches the special symbol start port 21 when the special symbol start port 21 is opened. Thus, the game ball can be launched by releasing the pushing operation of the firing stop button. Such an operation is called “stopping”. If this stopping is performed, the consumption of the game ball is suppressed, and there is a possibility that the sales of the game store in which the ball game machine 1 is installed may decrease.

  However, in the bullet ball game machine 1, the period of the general electric power release end interval in each special symbol start opening opening game is not constant (indefinite). Therefore, the period from the end of opening the special symbol start port 21 to the start of opening the special symbol start port 21 in the next special symbol start port opening game is not constant (indefinite). Therefore, the game ball cannot be launched aiming at opening of the special symbol start port 21. Thereby, the stop hit by the player can be prevented.

  In addition, the period of the public power release end interval in the first special symbol start opening game is set to 5.0 seconds, for example. In the first special symbol start-up opening game, the normal power release end interval is in the second and subsequent special symbol start-up opening games (for example, 0.5 seconds, 1.0 second, or 1.5 seconds). Compared to, it is set for a longer period. The reason for this will be described next.

  As described above, the period of the opening period for the opening of the normal electric power for the first special symbol opening opening game (the right-hand suggestion period shown in FIG. 10A) is set to 5.0 seconds, for example, as described above. Yes. In the first special symbol start-up opening game, a right-handed suggestion effect screen (see FIG. 5B; right-handed suggestion period) is displayed on the effect display means 15 during the opening period of the public call opening (5.0 seconds). Therefore, it can be collected around the special symbol starting port 21.

  However, depending on the disposition state of the obstacle nail on the game board 2 and the disposition position and size of the special symbol starting port 21, 5.0 seconds have elapsed since the start of the right-handed game (that is, the start of the right-handed game instruction). However, it is conceivable that the game balls cannot be sufficiently collected at the special symbol starting port 21. In this case, it is possible to set the length of the interval between the start of the electric train opening for more than 5.0 seconds, but in this case, after the normal symbol (winning symbol) is stopped on the normal symbol display means 31 (on the effect display means) This is not preferable because a very long interval is left before the start of the special symbol start opening game.

  In the special symbol starter opening game in this embodiment, from the start of the first opening (first half part, for example, opening for 3.0 seconds) at the special symbol starter 21 to the later opening (second half part). For example, the period until the end of (release for 3.0 seconds) is 7.0 seconds including an interval of 1.0 seconds. In addition, since the game ball that has entered the special symbol start opening 21 is not held, it is sufficient that only one start ball enters during the special symbol start opening opening game.

  In this case, the assumed pitching period in the second special symbol start-up opening game is set to 1.5 seconds (if a right-handed game is performed, the game will be played shortly after the start of the special symbol start-up opening game. On the other hand, the assumed entry period in the first special symbol start-up opening game is set relatively long as 5.9 seconds. In FIG. 10 (b), the special symbol start opening 21 at the end of the assumed pitching period of 5.9 seconds (game ball entering at the latest possible timing) during the first special symbol start opening opening game. The case where the special winning opening opening game is executed based on the game ball that has entered the ball is described as an example.

  By the way, since the assumed entry period in the first special symbol start opening game is long, the period from the elapse of the assumed entry period (5.9 seconds) to the end of the special symbol start opening game is The remaining opening period (1.1 seconds) of the special symbol start port 21 is a period obtained by adding a discharge confirmation period (for example, 2.0 seconds) and a normal power release opening interval. And, if the public train opening end interval is set to a relatively short period, the first special winning opening opening game (the special winning opening executed (generated) based on the first special symbol starting opening opening game) There is a risk that the next round, that is, the second lottery of normal symbols, may start before the (open game) ends.

Therefore, in the ball game machine 1, the period of the public power release end interval of the first special symbol start opening opening game (for example, 5.0 seconds) is the end of the public power release end of the second special symbol start opening opening game. It is set to a time longer than the interval period (for example, either 0.5 second, 1.0 second, or 1.5 second). Thereby, the start timing of the 2nd normal symbol lottery can be made later than the end timing of the 1st special prize opening opening game. This prevents the normal symbol lottery from being executed during the end timing of the first special prize opening game, that is, the period when the winning probability of the normal symbol lottery is low (the normal symbol low probability period shown in FIG. 10B). Can do.

  In the second and subsequent special symbol start opening games, from the start of opening the special symbol start port 21 (start of the first half opening) to the end of opening the special symbol start port 21 (end of the second half opening). The period is not limited to 7.0 seconds, but the special symbol variation time (for example, 0.6 seconds), the special symbol determination time (for example, 0.5 seconds), and the special prize opening game (for example, 6.5 seconds) is preferably shorter than a period (for example, 7.6 seconds). In this case, the special symbol starting port 21 is closed before the special winning opening opening game corresponding to the special symbol starting port opening game is ended. Therefore, it is reliably prevented that two (plural) special prize opening games are executed in correspondence with one special symbol start opening game. The ball game machine 1 is based on the premise that a special symbol opening opening game and a special prize opening opening game correspond one-on-one during a series of jackpot games. If the special prize opening opening game is executed twice corresponding to the game, the game performance of the ball game machine 1 may be lost. However, since it is reliably prevented that two (plural) special prize opening opening games are executed in response to the first special symbol start opening opening game, the game characteristics of the ball game machine 1 may be lost. There is no.

When the final special prize opening game is finished, the series of jackpot games is finished. The presence / absence or type of the special winning opening opening end interval (opening end interval) in the final special winning opening opening game is the type of the special symbol corresponding to the special winning opening opening game (symbol “1”, symbol “2”). , Symbol “3” or symbol “4”).
FIG. 12 is a diagram for explaining the special winning opening release end interval of the final (30th) special winning opening release game. The final special prize opening game is when the so-called limiter is activated.

In this embodiment, the special winning opening opening end interval (1) (first interval), the special winning opening release end interval (2) and the special winning opening release end interval (3) (second) Three types of special winning opening opening end intervals are provided.
When the special symbol corresponding to the last special prize opening game is “2”, the special prize opening release interval (1) is set as the special prize opening completion interval in the last special prize opening game. Executed. The symbol “2” is a so-called normal symbol, and the gaming state of the ball game machine 1 is in the normal mode after the final special prize opening game is completed (that is, after a series of jackpot games are completed).

  The length of the special winning opening opening end interval (1) is set to a predetermined first period (for example, 10 seconds). In the special winning opening opening end interval (1), an effect for ending is executed over the entire period. Specifically, the screen shown in FIG. 5L is displayed on the effect display means 15. Further, the sound generating means 13 outputs sound corresponding to the screen of FIG. 5L. Further, the effect lamp 17 is turned on / off in a manner corresponding to the screen of FIG. 5L.

After the elapse of the special winning opening opening end interval (1), the special winning opening release game ends. Thereafter, the gaming state of the ball game machine 1 becomes the normal mode. Therefore, the revival jackpot game is not executed. The selection probability of the symbol “2” is 50%.
When the special symbol corresponding to the last special prize opening game is “3”, the special winning opening release interval (2) is set as the special winning opening release interval in the final special winning opening game. Executed. The symbol “3” is a so-called short-time symbol, and after the final special prize opening game is completed (that is, after a series of jackpot games are completed), the game state of the ball game machine 1 is in the short-time mode.

  The length of the special winning opening opening end interval (2) is set to a period (for example, 20 seconds) obtained by adding a first period and a predetermined second period (for example, 10 seconds). In the special winning opening opening end interval (2), an effect for ending is executed over a first period (for example, 10 seconds) from the start of the interval. After the elapse of the first period, an effect for revival is then performed over the second period. In the second period, the screen shown in FIG. 5M is displayed on the effect display means 15. Further, the sound generating means 13 outputs sound corresponding to the screen shown in FIG. 5M. Further, the effect lamp 17 is turned on / off in a manner corresponding to the screen shown in FIG. 5M. After the end stage production process ends, “0” is set (stored) in the early stage flag 72 (step S70). Thereafter, the processing by the effect control board 60 ends.

After the elapse of the special winning opening opening end interval (2), the special winning opening release game is finished, and then the revival jackpot game is executed. The selection probability of the symbol “3” is 40%.
When the special symbol corresponding to the last special prize opening game is “4”, the special prize opening release interval (3) is set as the special prize opening completion interval in the last special prize opening game. Executed. The symbol “4” is a so-called short-time symbol, and after the final special prize opening game is completed (that is, after a series of jackpot games are completed), the game state of the ball game machine 1 is in the short-time mode.

  The length of the special winning opening opening end interval (3) is set to a period (for example, 50 seconds) obtained by adding the first period, a predetermined third period (for example, 30 seconds), and the second period. Has been. In the special winning opening opening end interval (3), an effect for ending is executed over a first period (for example, 10 seconds) from the start of the interval. After the elapse of the first period, an effect corresponding to the variation of the normal symbol is then executed over the third period. In this third period, a symbol change screen (see FIG. 5A) is displayed on the effect display means 15, and a plurality of effect symbols are scroll-displayed at high speed from top to bottom on this symbol change screen (FIG. 5A). Then, the effect design scroll-displayed at high speed is not shown). In addition, sound corresponding to the scroll display is output from the sound generation means 13. Further, the effect lamp 17 is turned on / off in a manner corresponding to the scroll display. After the elapse of the third period, an effect for revival is then executed over the second period. Specifically, the screen shown in FIG. 5M is displayed on the effect display means 15. After the end stage production process ends, “0” is set (stored) in the early stage flag 72 (step S70). Thereafter, the processing by the effect control board 60 ends.

After the elapse of the special winning opening release end interval (3), the special winning opening release game is finished, and then the rebirth jackpot game is executed. The selection probability of the symbol “4” is 8%.
In addition to the screen shown in FIG. 5M, a screen for promoting a so-called right-handed game (a right-hand suggesting effect screen, for example, a screen as shown in FIG. 5B) may be displayed. Further, the screen shown in FIG. 5M may incorporate an image imitating the board surface of the game board 2 in the right-handed game shown in FIG. 5B and a message display “Please make a right-handed” shown in FIG. 5B. .

If the special symbol corresponding to the special prize opening game is “1”, the same special prize opening opening interval is executed as when the limiter is not activated, and the middle stage production (midboard process) is continued. The series of jackpot games will not end.
That is, when the special symbol corresponding to the last special symbol lottery is the symbol “1”, the ending effect is not executed. On the other hand, if the special symbol corresponding to the final special symbol lottery is symbol “2”, symbol “3” or symbol “4”, an ending effect is executed.

  If the special symbol corresponding to the last special symbol lottery is “2”, the special prize opening game will end immediately after the ending effect, whereas the special symbol corresponding to the final special symbol lottery will end. When the symbol is “3”, the revival effect is executed after the ending effect. When the special symbol corresponding to the final special symbol lottery is the symbol “4”, the normal symbol variation effect and the revival effect are executed in this order after the ending effect.

  13A and 13B are flowcharts showing the flow of control by the effect control board 60 at the start of the special prize opening opening game. When the CPU 61 of the effect control board 60 receives the special winning opening opening start interval command transmitted by the main control board 40 (command transmission unit 45 thereof) in step S44 of FIG. 8B (YES in step S61), the value of the opening flag 72 Is checked (step S62). When the value of the early stage flag 72 is “0” (NO in step S62), the CPU 61 releases the number of times of the special prize opening based on the type of the limiter designation 2 command received simultaneously with the special prize opening opening interval command. Whether it is a game is determined (steps S63, S65).

  When the type of the limiter designation 2 command received by the command receiving unit 65 is F701H (the value of the mode data is “F7” and the value of the event data is “01”), that is, the first special prize opening game. In the case (when it is the first winning of the special symbol lottery; YES in step S63), an effect that a series of jackpot games has been started is executed (S64: first effect process). Specifically, the effect control board 60 displays the screen shown in FIG. 5D on the effect display means 15. In addition, the sound control unit 67 of the effect control board 60 outputs sound corresponding to the screen of FIG. 5D. Furthermore, the lamp control unit 68 of the effect control board 60 performs lighting control of the effect lamp 17 in a manner corresponding to the screen of FIG. 5D. After the first effect process ends, the process by the effect control board 60 ends.

  In addition, when the type of the received limiter designation 2 command is any one of F702H, F703H, or F704H, that is, when it is the 2nd to 4th special prize opening game (2-4 consecutive wins in the special symbol lottery) If NO in step S63 and NO in step S65, an early stage effect is executed in the series of effect operations (S66: early stage process). Specifically, the effect control board 60 displays the screen shown in FIGS. 5E to 5G or the screen shown in FIG. 5H on the effect display means 15. In addition, the sound control unit 67 of the effect control board 60 outputs sound corresponding to each screen. Furthermore, the lamp control unit 68 of the effect control board 60 performs lighting control of the effect lamp 17 in a manner corresponding to each screen. After the opening process of step S66 is completed, a value of “1” is set (stored) in the opening flag 72. And the process by CPU61 of the production | presentation control board 60 is complete | finished. Further, when the type of the received limiter designation 2 command is F705H or more (F705H, F706H, F707H,..., F71DH, F71EH), that is, the fifth or later special prize opening game (special symbol). If the lottery is won five or more times consecutively (NO in step S63 and YES in step S65), the process proceeds to step S71.

On the other hand, when the value of the early flag 72 checked in step S62 is “1” (YES in step S62), the process proceeds to step S71 on condition that the limiter is not operated (NO in step S68). . When the type of the received limiter designation 2 command is any of F032H, F033H, or F034H, that is, when the limiter is activated (YES in step S68), an effect that the series of jackpot games ends (the final stage) (Direction) is executed (S69: final process). After the end stage processing is completed, “0” is set (stored) in the early stage flag 72 (step S70). Thereafter, the processing by the effect control board 60 ends.

Next, in step S71, it is determined whether or not the value of the lottery enable flag 74 is “1”. The lottery enable flag 74 is a flag for indicating whether or not the execution scenario determination lottery is necessary.
The effect scenario determination lottery determines whether or not to execute the effect operation of the effect pattern and determines the effect scenario to be executed when it is determined to execute the effect operation of the effect pattern. This effect scenario determination lottery is executed at the start timing of the special prize opening opening game (step S72).

  As a result of the effect scenario determination lottery, when it is determined to execute the predetermined effect (YES in step S73), the number of effect patterns included in the scenario selected by the scenario determination lottery is set in the lottery available counter 75 ( At the same time as step S77, the main control board 40 sets a value of “0” in the lottery enable flag 74 (step S74), and proceeds to step S75. On the other hand, when the value of the lottery enable flag 74 is “0” (NO in step S71), the process proceeds to step S75.

  Next, in step S75, it is determined whether or not the value of the effect enable flag 73 is “1”. The effect enable flag 73 is a flag for indicating whether or not the effect can be executed by the effect display means 15, the sound generation means 13, or the effect lamp 17. In a state where the execution can be performed, a value “1” is set (stored) in the effect enable flag 73. In the state where the execution cannot be performed, such as during the execution of the effect, “0” is set (stored) in the effect enable flag 73.

  When the value of the effectable flag 73 is “1” (YES in step S75), a value of “0” is set in the effectable flag 73 (step S76). Then, the middle stage production (middle board processing) is executed (S78: production pattern execution). Specifically, the effect control board 60 displays the screen shown in FIG. 5I, the screen shown in FIG. 5J, the screen shown in FIG. In addition, the sound control unit 67 of the effect control board 60 outputs sound corresponding to each screen. Furthermore, the lamp control unit 68 of the effect control board 60 performs lighting control of the effect lamp 17 in a manner corresponding to each screen.

  After the production of the middle stage is finished, the value “1” is set (stored) in the production possible flag 73 and the value of the lotterable counter 75 is decremented (“−1”) (steps S79 and S80). If the value of the lotterable counter 75 becomes “0” (YES in step S81), a value of “1” is set (stored) in the lotterable flag 74 (step S82). In other words, a value of “1” is set (stored) in the lottery available flag 74 at the timing when the rendering operations of all the rendering patterns included in the previously determined rendering scenario are completed by the rendering scenario determination lottery (step). S82), it becomes possible to execute the production scenario determination lottery. In other words, the production scenario determination lottery is not executed unless the production operation of all the production patterns included in the production scenario determined last time is finished by the production scenario decision lottery. Thereafter, the processing by the effect control board 60 ends.

On the effect display means 15, the sound generation means 13, or the effect lamp 17, an effect according to the effect scenario determined by lottery by the effect scenario determination lottery is executed.
FIG. 14 is a diagram illustrating an example of an effect scenario determination table used in the effect scenario determination lottery.
Specifically, as shown in FIG. 14, a plurality (type) of production scenarios are prepared for the ball game machine 1. The effect scenario determination lottery determines one effect scenario from a plurality of effect scenarios. In this embodiment, the case where six types of effect scenarios are prepared for the ball game machine 1 is described as an example, but it goes without saying that a larger number of effect scenarios may be prepared. Yes.

  As shown in FIG. 14, a scenario “XXXA” is prepared as an effect scenario in which the number of effect patterns is 4 in this bullet ball game machine 1. In the scenario “XXXA”, after the execution of the effect pattern “X” is repeated three times, the effect pattern “A” is executed once. In addition, a scenario “XXA” and a scenario “XXB” are prepared as production scenarios with three production patterns. This scenario “XXA” is an effect scenario in which the effect pattern “A” is executed once after the effect pattern “X” is executed twice. The scenario “XXB” is an effect scenario in which the effect pattern “B” is executed once after the effect pattern “X” is executed twice. Also, scenario “XB” and scenario “XC” are prepared as production scenarios with two production patterns. The scenario “XB” is an effect scenario in which the effect pattern “B” is executed once after the effect pattern “X” is executed once. The scenario “XC” is an effect scenario in which the effect pattern “C” is executed once after the effect pattern “X” is executed once. In addition, a scenario “C” in which an effect pattern “C” is executed once is provided as an effect scenario with one effect pattern. The effect pattern “X” is not necessarily limited to a single type of effect pattern, but the length of the effect pattern “X” is set to be the same.

In the effect scenario determination lottery, it is determined that the effect pattern is not executed (displayed as “-” in the effect scenario determination table shown in FIG. 14). In other words, the effect scenario determination lottery serves as both a lottery for determining whether or not to perform the effect operation of the effect pattern and a lottery for determining the effect scenario when the effect operation of the effect pattern is executed. .
Which of the six production scenarios is selected by lottery depends on the number of remaining game unit periods at the time of the production scenario decision lottery (the number of remaining random fluctuations (the number of consecutive executions allowed thereafter) The number of probability variation modes to be performed)) is different.

In other words, the lottery table employed is different based on the number of consecutive probability variation executions derived from the limiter designation 1 command (or limiter designation 2 command) received at the timing of step S61 in FIG. 13A.
Then, when the effect pattern is executed, the display control unit 66 reads display data of the effect pattern included in the effect scenario determined by the effect scenario determination lottery from the effect pattern data storage unit 70. And the display control part 66 carries out display control of the production | presentation display means 15 based on this display data. In addition, the sound control unit 67 reads out the sound data of the effect pattern included in the effect scenario determined by the effect scenario determination lottery from the effect pattern data storage unit 70. Then, the voice control unit 67 controls the output operation of the voice generation unit 13 based on the voice data. Further, the lamp control unit 68 reads out the lamp control data of the effect pattern included in the effect scenario determined by the effect scenario determination lottery from the effect pattern data storage unit 70. The lamp control unit 68 controls lighting / extinguishing of the effect lamp 17 based on the lamp control data stored in the effect pattern data storage unit 70.

  Specifically, an effect scenario with a smaller number of effect patterns to be included is selected as the number of remaining game unit periods in the series of jackpot games is reduced. In the case where an effect is executed as a result of the effect scenario determination lottery, the average number of effect patterns included in the effect scenario selected by the effect scenario determination lottery is 1 when the remaining 2 sets or more and the remaining 4 sets or less are left. 1.65 if there are 5 sets or more and 9 sets or less, 1.93 if there are 10 sets or more and 14 sets or less, and 2.39 if 15 sets or more and 19 sets or less are left In the above case, it is 2.93. That is, as the number of remaining game unit periods in a series of jackpot games decreases, the number of average effect patterns to be included decreases.

FIG. 15 is a diagram for explaining the display start timing of the production scenario at the time of production of the middle stage. In FIG. 15, a case where the scenario “XXA” is determined by lottery in the effect scenario determination lottery will be described as an example of the effect scenario.
In this case, during the period required to execute the effect of the effect pattern X, the normal symbol corresponding to the next special symbol start opening game is started immediately after the end of the special symbol start opening game. (I.e., when at least one start memory is stored in the normal symbol start storage unit 51 throughout a series of jackpot games, and within the previous additional period, a game ball is sent to the special symbol start port. Is set to a period slightly less than twice the game unit period in the

  In addition, during the period required for the production of the production pattern A, the normal symbol corresponding to the next special symbol start opening game is started immediately after the end of the special symbol start opening game. (I.e., when at least one start memory is stored in the normal symbol start storage unit 51 throughout a series of jackpot games, and the game ball is placed at the special symbol start port within the previous additional period. The period is set to be slightly less than three times the game unit period in the case of entering a ball).

  Therefore, as shown in FIG. 15 (a), immediately after the end of each special symbol start opening game, the variation of the normal symbol corresponding to the next special symbol start opening game is started. If there is (ie, at least one normal symbol is stored in the normal symbol start storage unit 51 through a series of jackpot games), the first set (the first set counted from the start of the production of the middle stage, In the present embodiment, the game unit period start (corresponding to the fifth set) is the start (special prize opening opening game start) timing, the third set (the third set counting from the start of the production of the middle stage), in this embodiment , The start timing of the game unit period of the seventh set) and the start of the game unit period of the fifth set (corresponding to the ninth set in the present embodiment, which is the fifth set counting from the start of the middle stage production) T In accordance with the timing, so that each performance pattern X, the effect pattern X and the effect pattern A is performed.

  As described with reference to FIGS. 10 and 11, in this bullet ball game machine 1, various measures are taken because the normal symbol lottery is not executed with a low probability (1/300) during the jackpot game. . However, the above-mentioned measures are based on the assumption that the game ball enters the special symbol start opening within the previous additional period, and when the game ball enters the special symbol start opening after the previous additional period. The normal symbol lottery cannot reliably prevent the execution of the low probability (1/300). When the normal symbol lottery is executed with a low probability (1/300), the game unit period including the fluctuation of the normal symbol corresponding to the normal symbol lottery becomes remarkably long. Moreover, this period is not only long but indefinite.

Also, if the game ball does not enter the normal symbol start port 18 during the jackpot game, or if the game ball does not pass through the normal symbol start gate 27 during the jackpot game and the number of start memories becomes zero, Or a plurality of game unit periods may become long.
And when the interval from the end of the production to the start of the next production is fixed, as shown in FIG. 15 (b), for example, when the first game unit period in the middle board process is long, There is a possibility that the start timing of the effect pattern to be executed next (second effect pattern X) may be shifted before the start timing of the third set of game unit periods. Further, the start timing of the next effect pattern (effect pattern A) may be shifted before the start timing of the fifth game unit period.

  On the other hand, as shown in FIG. 15C, a case where the start timing of the effect is fixed at the start of a predetermined game unit period will be described. For example, the start timing of the first effect pattern X is matched with the start timing of the first set of game unit periods, the start timing of the second effect pattern X is matched with the start timing of the third set of game unit periods, If the start timing of the third performance pattern X is matched with the start game unit period of the fifth game unit period, for example, the period of the first set of game unit periods in the mid-game process becomes longer. The production of the first production pattern X ends in the middle of the game unit period of the eye, and the production is not performed for a long time until the production of the second production pattern X starts after the production of the first production pattern X. Therefore, there is a possibility that the production is delayed.

On the other hand, as shown in FIGS. 13A and 13B, in the middle stage production of this embodiment, only at the start of the special winning opening opening game, that is, when the special winning opening release start interval command is received (YES in step S61). It is determined whether or not to execute the effect. Therefore, in other cases, the production operation of the production pattern is not started.
In this embodiment, the lottery for determining whether or not the production scenario determination lottery performs the production operation of the production pattern and the lottery for determining the production scenario when performing the production operation of the production pattern are performed. These lotteries may also be performed individually.

  That is, every time the special winning opening opening start interval command is received (YES in step S61), whether or not the value of the effect enable flag 73 is “1”, that is, the effect display means 15, the sound generation means 13 and It is determined whether or not an effect by the effect lamp 17 is being executed. Only when the special winning opening opening start interval command is received and the value of the effect possible flag 73 is “1” (YES in step S61, YES in step S75), the effect display means 15, the sound generation means 13 and The execution of the effect by the effect lamp 17 is started.

As shown in FIG. 15 (d), after the end of the effect operation of the effect pattern, the start of the effect operation of the effect pattern to be executed next starts the next special prize opening game that is executed at the end of the effect operation. Is held until.
Therefore, even if one (or a plurality) of game unit periods included in a series of jackpot games is long, the start timing of the effect pattern to be executed next can be matched with the start timing of the game unit period. it can. Thereby, the start timing of the effect pattern in the effect display means 15 can be matched with the progress of a series of jackpot games.

In addition, since the effect pattern is executed at the start of the symbol change of the next special symbol display means 29 at the end of execution of the effect pattern, it is possible to wait for a long time from the end of the execution of the previous effect pattern to the start of execution of the next effect pattern. Absent.
As described above, according to this embodiment, the special winning opening release end interval (1) and the special winning opening release end interval (1) are used as the special winning opening release end interval of the final (30th) special winning opening release game. ) And a special winning opening opening end interval (3) for a longer period of time. During the special winning opening opening end interval (3), a high-speed scroll display of the effect symbol (normal symbol effect operation, see FIG. 5A) is displayed on the effect display means 15.

  When the normal mode is executed after the end of the jackpot game (special game state), an effect for ending is displayed on the effect display means 15, and a high-speed scroll display of the effect symbol is displayed after the end of the jackpot game. Therefore, when the effect display means 15 displays a high-speed scroll display of the effect symbol after the effect for the ending, the player recognizes that the jackpot game is ended and the player is in the normal mode.

Therefore, if the special winning opening release end interval (3) is adopted when the short time mode (high probability mode) is executed after the end of the jackpot game, the state of the ball game machine 1 is in the short time mode. Nevertheless, the player will recognize that he is in normal mode.
In this case, during the special winning opening opening end interval (3), an effect for ending is displayed on the effect display means 15, then a high-speed scroll display of effect symbols is displayed, and then the time display mode is displayed on the effect display means 15. Will be displayed. Then, by notifying that the short-time mode is executed, the player will recognize that the gaming state of the ball game machine 1 is in the short-time mode. It can give a big surprise.

  In addition, since the high-speed scroll display of the effect symbol is displayed on the effect display means 15 both in the case where the normal mode or the short time mode is executed after the jackpot game, conversely, there is a period of time after the end of the jackpot game. Even after the lapse, the player does not know whether the normal mode is being executed or whether the time reduction mode is being executed. Therefore, a player's expectation can be maintained. Thus, the gameability of the ball game machine 1 can be improved.

Although one embodiment of the present invention has been described above, the present invention can be implemented in other forms.
For example, a series of jackpot games may be composed of a plurality of predetermined rounds. This jackpot game is special until a predetermined condition is satisfied (until a predetermined time (for example, 30 seconds) elapses or a predetermined number (for example, 10) of game balls enter the special winning opening 22). The operation of opening the winning opening 22 is defined as one round, and such an operation is performed for a predetermined number of rounds (for example, 2 to 15 rounds). In such a case, whether or not to execute the jackpot game is determined by a special symbol lottery. And the jackpot game is comprised by the one special prize opening | opening game which has the said multiple (for example, 2-15 rounds) rounds.

  That is, a special symbol lottery (a jackpot lottery) for determining whether or not to execute a jackpot game is executed based on a game ball entering the special symbol start port 21. When the result of the special symbol lottery is a win (big hit), the big hit game is executed. After the jackpot game is over, either the normal mode or the short time mode (high probability mode) is executed. Then, as a special winning opening opening end interval (1), which is a period from the closing operation of the second opening / closing plate 25 to the closing end of the special winning opening 23 in the last round, as shown in FIG. ) (First interval), special winning opening opening end interval (2) and special winning opening opening end interval (3) (second interval) may be used.

In addition, as the special winning opening opening end interval, at least two types of special winning opening opening, special winning opening opening end interval (1) (first interval) and special winning opening opening end interval (3) (second interval) are provided. It is sufficient that an end interval is prepared.
Further, the revival effect may be omitted in the special winning opening opening end interval (3) (second interval).

Further, the effect lamp 17 is not limited to the configuration provided on the board surface of the game board 2, and an effect lamp for raising the game atmosphere may be provided on the front surface of the front door 4.
In addition, the assumed entry period (pre-addition period) for the second special symbol opening opening game is not limited to 1.5 seconds, but 1.2 seconds (one game ball is special in 2.0 balls) It is preferable that the time is equal to or longer than 1.8 seconds (when one game ball enters the special symbol start port 21) for 1.8 seconds or more when entering the symbol start port 21).

The counter is not limited to a configuration in which a plurality of counters are provided for counting the number of times of continuous execution of the probability variation that the probability variation mode continuously executes (the number of times that the special prize opening game is continuously executed in the probability variation mode). It is sufficient that at least one is provided.
In the above-described embodiment, the first opening / closing plate 23 and the second opening / closing plate 25 have been described as being controlled by the main control board 40, but these opening / closing boards 23, 25 are connected to the effect control board 60. It may be controlled based on a control command given from the main control board 40 to the effect control board 60.

The electric block diagram shown in FIG. 3 shows a configuration in which the main control board 40 and the effect control board 60 are directly connected, but the two boards 40, between the main control board 40 and the effect control board 60, A relay board that relays transmission / reception of 60 control commands may be interposed.
Further, although the sound generation means 13 has been described as being controlled by the effect control board 60, it may be controlled by a sound control board provided separately from the effect control board 60. This sound control board may be connected to the main control board 40 and control the sound generating means 13 based on a control command given from the main control board 40, or may be connected to the effect control board 60 to produce effects. The sound generation means 13 may be controlled based on a control command given from the control board 60.

  Furthermore, although it has been described that the effect lamp 17 is controlled by the effect control board 60, the effect lamp 17 may be controlled by a lamp control board provided separately from the effect control board 60. This lamp control board may be connected to the main control board 40 and control the effect lamp 17 based on a control command given from the main control board 40, or may be connected to the effect control board 60 for effect control. The effect lamp 17 may be controlled based on a control command given from the substrate 60.

  Further, in the ball game machine 1, it is desirable that the profit state given to the player in the special symbol start opening game is higher than the profit state given to the player in the special prize opening game. When the number of winning balls for entering the special symbol starting port 21 is the same as the number of winning balls for entering the special winning port 22 or less than the number of winning balls for entering the special winning port 22 The number of game balls entering the special symbol start opening 21 in one special symbol start opening game is larger than the number of game balls entering the special prize opening 22 in one special winning opening opening game. You may set so that it may increase. Also, the number of game balls entering the special symbol start opening 21 in one special symbol start opening game is the same as the number of game balls entering the special prize opening 22 in one special winning opening opening game. If it is set to be less than the number of game balls entering the special prize opening 22 in one special prize opening opening game, the number of prize balls for entering the special symbol starting hole 21 However, the number of prize balls for entering the special prize opening 22 may be increased. Of course, the number of winning balls for entering the special symbol starting port 21 is larger than the number of winning balls for entering the special winning port 22, and the special symbol starting in one special symbol starting port opening game is started. It goes without saying that the number of game balls entering the mouth 21 may be set to be larger than the number of game balls entering the special prize opening 22 in one special prize opening opening game.

  The special symbol starting port 21 may be one in which a plurality of game balls cannot enter at the same time (that is, only one game ball can enter each). Then, in relation to the special symbol start port 21, instead of the first opening / closing plate 23, a pair of blades are provided, the closed state where the tip portions of the blades approach each other, and the tip portions of the blades are mutually connected. An electric tulip accessory provided so as to be openable and closable between the separated and expanded states may be provided. Furthermore, the number of special symbol starting ports 21 is not limited to one, and may be two or more. Further, the special symbol starting port 21 may be arranged at a position away from the special winning port 22 on the board surface of the game board 2.

  The special winning opening 22 may be one in which a plurality of game balls cannot enter at the same time (that is, only one game ball can enter at a time). Then, in relation to the special prize opening 22, instead of the second opening / closing plate 25, a pair of blades are provided, the closed state in which the tip portions of the blades approach each other, and the tip portions of the blades are separated from each other. An electric tulip accessory provided so as to be openable and closable with respect to the expanded state may be provided. Furthermore, the number of the special winning opening 22 is not limited to one and may be two or more.

  Further, the normal symbol starting area is not limited to the configuration in which the normal symbol starting gate 27 and the normal symbol starting port 18 are provided, and the normal symbol starting gate 27 may be provided. The structure which provides only one start port 18 may be sufficient. Alternatively, a configuration in which a total of three or more normal symbol start gates 27 and / or normal symbol start ports 18 may be provided.

  In addition, various design changes can be made within the scope of matters described in the claims.
