Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a ball game machine provided with a storage means for storing up to a predetermined number of game balls won in a winning section (start winning prize opening).

  In general, a pachinko gaming machine, which is one of the ball game machines, performs a jackpot lottery or the like in response to the winning of a game ball in a winning portion (starting winning opening) provided on the game board surface. That is, when a game ball wins at the start winning opening, for example, a random number is obtained and a lottery is performed to determine whether or not the game is a big hit, and the lottery result is displayed in a stopped state after the symbols are displayed on the symbol display device provided on the game board surface. The player is notified by a symbol variation effect (symbol pattern). In such a pachinko gaming machine, when a game ball is won at the start winning opening while the symbols are being displayed on the symbol display device (hereinafter referred to as “varying symbols”), up to a predetermined number of the game balls Deferred. Then, for example, the number of game balls held is informed to the player by turning on one hold ball provided on the game board surface for each winning game ball.

  Then, when a big win is won in the lottery using the random numbers described above, a special game consisting of performing a unit special game that makes it easy to win a big winning opening provided on the game board surface is executed. That is, a normally closed grand prize opening is opened, and for example, an operation (hereinafter referred to as “unit special game”) that is closed when a predetermined time elapses or a predetermined number of game balls are awarded to the big prize opening. Repeat a predetermined number of times. Such a pachinko gaming machine (hereinafter referred to as “first type pachinko gaming machine”) is described in Patent Document 1, for example.

Japanese Patent Application Laid-Open No. 11-299998

  In the conventional first type pachinko gaming machine described above, the number of game balls that can be held during symbol variation is restricted to, for example, a maximum of four. And even if more than the number of game balls that can be held during symbol variation wins the start winning opening, the big hit lottery triggered by the winning is not performed. As a result, after the number of reserved balls reaches the maximum during the symbol change, the player has stopped launching the game balls and waits for the game balls that have been reserved to be digested. As a result, the operating rate of the pachinko gaming machine is lowered, and there is a problem that it may give a player a sense of wasting time.

  Further, in the conventional first-class pachinko gaming machines, the probability of winning a jackpot is generally set to about 1/200 to 1/350. Therefore, in order to win a jackpot, the player averages 200 It is necessary to make a game ball win at the start winning opening about 350 times. If a big win is won, a predetermined unit special game is normally repeatedly executed for a predetermined number of rounds. As a result, the game tends to be monotonous, and there is a problem that the player feels bored. Furthermore, if the jackpot symbol is not displayed for a long time, the player may be skeptical about the pachinko gaming machine.

  The present invention has been made in view of the above-described problems, and a first object thereof is to effectively prevent a player from stopping the launch of a game ball during a pattern change, and to provide a ball game machine. An object of the present invention is to provide a ball game machine that can prevent a decrease in the operating rate of the machine. Furthermore, the second object is to provide a ball game machine that can provide more interest to the player by increasing the frequency of winning the jackpot while maintaining the profit return rate to the player. .

A second detection means for detecting a game ball that has not been stored in the means, and a first jackpot lottery is performed in response to the detection of the game ball by the first detection means. The second jackpot lottery is to be performed upon detection.

  Thus, in the ball game machine according to the present invention, a winning portion provided on the game board surface, a storing means for storing up to a predetermined number of gaming balls won in the winning portion, and a gaming ball stored in the storing means First detection means for detecting a game, second detection means for detecting a game ball that has won the winning portion and has not been stored in the storage means, and a first jackpot for each detection by the first detection means A jackpot lottery means for performing a lottery and performing a second jackpot lottery for each detection by the second detecting means, and a variable provided on the game board surface when winning a jackpot in the first or second jackpot lottery And a special game executing means for repeatedly executing a unit special game that makes it easy to win a winning opening. When the special game executing means wins a jackpot in the first jackpot lottery Perform 1 unit special game is characterized by performing said second of said first unit advantageous second unit special game from the special game when the player wins the jackpot for the player in jackpot lottery.

  As a result, the special game execution means executes the second unit special game which is more advantageous to the player than the first unit special game when winning the jackpot in the second jackpot lottery. In addition, it is possible to effectively prevent the player from stopping the launching of the game ball, and it is possible to prevent a reduction in the operation rate of the ball game machine. Further, the special game executing means executes the first unit special game when winning a jackpot in the first jackpot lottery, and the second game when winning the jackpot in the second jackpot lottery. Since the unit special game is executed, it is possible to increase the frequency of winning the jackpot while maintaining the profit return rate to the player, and to provide more interest to the player.

  In the bullet ball game machine according to the present invention, the number of game balls that can be won in the variable winning opening in the second unit special game is larger than that in the first unit special game. As a result, the player can receive more prize balls in the second unit special game than in the first unit special game, so that the second unit special game can be received from the first unit special game. Can be advantageous to the person.

  Further, the ball game machine according to the present invention is characterized in that the time for making it easy to win the variable winning opening in the second unit special game is longer than that in the first unit special game. Thus, the player can win more game balls in the second unit special game than the first unit special game in the variable prize opening.

  Further, in the ball game machine according to the present invention, the number of prize balls for each winning of the game balls in the variable winning opening in the second unit special game is larger than that in the first unit special game. . Accordingly, since the player can receive more prize balls in the second unit special game than in the first unit special game, the player can receive the second unit special game in the first unit. It is possible to make the unit special game more advantageous than the special game.

  In the ball game machine according to the present invention, the storage means has at least a first effect mode and a second effect mode in which the symbol variation time is longer than the first effect mode. Thereby, since the symbol variation time of the second effect mode is longer than the symbol variation time of the first effect mode, in the case of the second effect mode, the symbol variation time is larger than that of the first effect mode during the symbol variation. The game ball can be won in the winning portion, and the game ball can be easily detected by the second detection means. As a result, in the second effect mode, the frequency of winning the jackpot in the second jackpot lottery is increased from that in the first effect mode, and the player can change the second effect mode from the first effect mode.

  Next, the configuration of the game ball storage device 20 constituting one of the characteristic parts of the ball game machine 1 according to the present invention will be described. 2, 3, and 4 are first, second, and third explanatory diagrams showing the internal configuration of the specific winning portion 12 and the game ball storage device 20 that is connected to the specific winning portion 12. FIG. 2 is a diagram illustrating a state in which the expansion device 13 is operated and the game balls A to E are continuously awarded to the specific winning unit 12. FIG. 3 is a diagram illustrating a state in which the game ball A is accommodated in the ball receiving unit 31 and the game balls B to E are stored in the game ball storage device 20. FIG. 4 is a diagram illustrating a state in which the game balls B to E are stored in the game ball storage device 20 and the game balls F are guided by the second path 25. Since the game ball storage device 20 shown in FIGS. 2 to 4 is disposed on the back side of the game board surface 10, it is not shown in the front view of the bullet ball game machine 1 shown in FIG.

  As shown in FIGS. 2 to 4, the game ball storage device 20 is provided with a plurality of paths for guiding the game ball, and passes through the prize ball detection device 12 a below the prize ball detection device 12 a of the specific winning portion 12. A game ball flow lower portion 21 for receiving the flow of the game ball is disposed. A first path (lower stage) 23 that guides a game ball extends in a substantially lower right direction via a shutter 29 in the right direction of the game ball lower portion 21. A storage ball detection device 22 that detects a game ball (storage ball) is disposed at the left end portion of the first path (lower stage) 23. A first path (upper stage) 24 is disposed above the first path (lower stage) 23, and a first start detection device 25 (first detection means) is provided in the middle of the first path (upper stage) 24. Is provided. The first path (lower stage) 23 and the first path (upper stage) 24 are provided with a desired inclination so that the game balls can be smoothly guided. A substantially disk-shaped rotating body 30 is disposed behind the first path (lower stage) 23 and the first path (upper stage) 24 (back side with respect to the paper surface). The rotating body 30 has a ball receiving portion 31 that can accommodate one game ball, and is rotated clockwise (in the direction of arrow Y shown in FIG. 4) or counterclockwise by the rotating body drive source 30a (see FIG. 5). It is rotated (in the direction of arrow X shown in FIG. 3).

  A shutter 29 disposed below the game ball lower portion 21 can move in the left-right direction, and the shutter 29 is opened and closed by a shutter drive source 29a. 2 and 3 show a state in which the shutter 29 is closed, and FIG. 4 shows a state in which the shutter 29 is moved leftward and opened. Below the shutter 29, a second path 26 for guiding the game ball extends vertically downward, and a second start detection device 27 (second second) for detecting the game ball that passes through the second path 26. Detection means) is provided.

  In addition, as described above, the game ball storage device 20 is disposed on the back side of the game board surface 10 so that its configuration is not visible to the player (see FIG. 1). It is more preferable if the portion is configured to be visible from the player. For example, it is possible to form the game board surface 10 using a transparent material and make the game ball storage device 20 visible to the player. Thereby, the player can directly visually check how the game ball is stored and how the game ball is guided to the first route (upper) 24 by the rotating body 30, so that the player can It becomes possible to provide an interesting interest.

  Next, the function of the game ball storage device 20 will be described. FIG. 2 shows a state where five game balls (A to E) have successively won the specific winning portion 12, and the first game ball A has passed through the stored ball detection device 22. When the storage ball detecting device 22 detects the passing of the game ball, a passing detection signal is transmitted, and one holding lamp 4 is turned on in response to the passing detection signal. The game ball A that has passed through the stored ball detection device 22 is guided to the rotating body inlet 23a by the first path (lower stage) 23. The rotating body entrance 23 a is a gate through which the game ball passes when the game ball is accommodated in the ball receiving portion 31 of the rotating body 30. In FIG. 2, the rotating body 30 is stopped with the ball receiving portion 31 in the lowest position. Therefore, when the game ball A is guided to the rotating body entrance 23 a, the gaming ball A is in the ball receiving portion 31 of the rotating body 30. Is housed in.

  Next, the winning game ball B passes through the storage ball detection device 22 in the same manner as the game ball A, and is guided to the rotating body inlet 23a by the first path (lower stage) 23, and the gaming ball B passes through the rotating body inlet 23a. Stored. When the storage ball detection device 22 detects the passage of the game ball B, one of the above-described holding lamps 4 is turned on (hereinafter the same). Similarly, the game ball C won next after the game ball B also passes through the storage ball detection device 22, is guided by the first route (lower stage) 23, and is stored on the left side of the game ball B (see FIG. 3). ). Similarly, a game ball D and a game ball E are also stored, and a state where four game balls (B to E) are stored in the first path (lower stage) 23 is shown in FIG.

  Next, the rotating body 30 containing the game ball A in the ball receiving portion 31 starts to rotate in the X direction (counterclockwise direction), and the ball receiving portion 31 overlaps the rotating body outlet 24a as shown in FIG. End the rotation. The rotating body outlet 24a is disposed at the left end portion of the first path (upper stage) 24, and the game balls accommodated in the ball receiving portion 31 of the rotating body 30 are discharged to the first path (upper stage) 24 side. It is a gate through which game balls pass. When the rotating body 30 starts rotating in the X direction, one of the on-hold holding lamps 4 is turned off (the same applies hereinafter).

  When the rotation of the rotating body 30 shown in FIG. 3 is completed, the game ball A accommodated in the ball receiving portion 31 is discharged to the first path (upper stage) 24 side through the rotating body outlet 24a. The game ball A discharged to the first path (upper stage) 24 side is guided by the first path (upper stage) 24 and passes through the first start detection device 25. Next, as shown in FIG. 4, the rotating body 30 starts to rotate (reverse) in the Y direction (clockwise) and returns to the position where the ball receiver 31 is at the lowest position (see FIG. 2).

  Further, the time from when the rotating body 30 starts to rotate in the X direction from the position shown in FIG. 2 until it reverses and returns to the position corresponds to the symbol variation time. That is, the rotator 30 guides one game ball from the first path (lower stage) 23 to the first path (upper stage) 24 every symbol variation time. Since the ball game machine 1 according to the present embodiment has a plurality of symbol variation times as will be described later, it has a rotation mode corresponding to each symbol variation time. In addition to the mode that rotates in the X direction and then reverses and returns in the Y direction as described above, each rotation mode is a mode that rotates in the Y direction and then reverses and returns in the X direction. The rotation mode may be one rotation, or any rotation mode in which each symbol variation time is one cycle.

  Next, as shown in FIGS. 3 and 4, when four game balls (B to E) are stored in the first path (lower stage) 23, the stored ball detection device 22 stops (stores) the game balls E. Is detected. When the storage ball detection device 22 detects the stop of the game ball, a stop detection signal is transmitted, and the control of the shutter drive source 29a is started with the stop detection signal as an opportunity, and the shutter 29 is opened and closed. That is, when the storage ball detection device 22 detects the stop of the game ball, the shutter 29 moves to the left and is opened (see FIG. 4), and when the storage ball detection device 22 does not detect the stop of the game ball, the shutter 29 is It moves to the right and is closed (see FIG. 2). As shown in FIG. 4, when the shutter 29 is opened, the game ball F flows down to the second path 26 side and passes through the second start detection device 27 by the guidance of the second path 26. Similarly, the game ball G won next after the game ball F passes through the second start detection device 27 by the guidance of the second path 26.

  As described above, the gaming ball storage device 20 according to the present embodiment stores up to four gaming balls that have won the specific winning unit 12 in the first path (lower stage) 23, and the stored gaming balls are the first ones. The game balls that have not been stored pass through the second start detection device 25. Note that the mechanism for distributing the game balls to either the first route or the second route has a simple structure substantially constituted by the storage ball detection device 22 and the shutter 29, but the game balls are arranged in the first route or the second route. This is a configuration that can be reliably distributed to any of the routes.

  Next, an outline of the game of the ball ball game machine 1 having the above configuration will be described. When the player operates the ball handle, the game ball is launched, guided by the guide rail 2 and released above the game board surface 10. While the game balls come into contact with the windmill 19 or the nail to change the falling direction, a part of the game balls enter the winning opening 16, 16, or the specific winning section 12, and the winning opening 16, 16, or the specific winning section 12 The game balls that have not entered the game enter the out port 18. When the game balls win the winning openings 16, 16, for example, five prize balls are paid out to the player from the prize ball payout exit.

  Next, when the game ball passes through the operation gate 17, a normal symbol lottery is performed in response to a passing signal from the operation gate passage detection device 17a, and the normal symbol display unit 3 starts to change the normal symbol. Then, for example, when 30 seconds have elapsed since the start of the fluctuation, the normal symbol stops in the form of the lottery result. At this time, if the stop mode of the normal symbol is a predetermined hit mode, the expansion devices 13 and 13 of the specific winning unit 12 are operated (FIGS. 2 to 4), and are held for 0.5 seconds, for example. During this time, since the opening width of the specific winning portion 12 is enlarged, it becomes easy to win the specific winning portion 12. Further, if the normal symbol stop mode is a predetermined off mode, the expansion devices 13 and 13 of the specific winning unit 12 are not operated, but even in this case, it is possible to win the specific winning unit 12. If the game ball passes through the gates 17 and 17 while the normal symbol is changing in the normal symbol display unit 3, the corresponding change is suspended and sequentially executed.

  Next, when a game ball wins the specific winning portion 12, for example, four award balls are paid out to the player from the award ball payout opening in response to a detection signal from the prize ball detection device 12a. A game ball that has won the specific winning unit 12 is detected for the first start via the first path (lower stage) 23 of the game ball storage device 20, the ball receiving unit 31 of the rotating body 30, and the first path (upper stage) 24. The route is either guided to the device 25 or guided to the second start detection device 27 via the second path 26.

  That is, if four game balls are not stored in the game ball storage device 20, the shutter 29 is closed (see FIG. 2), so the game ball newly won in the specific winning unit 12 is the first start detection device. 25, and is detected by the first start detection device 25. On the other hand, if four game balls are already stored in the game ball storage device 20, the shutter 29 is opened (see FIG. 4), and the next game ball won is guided to the second start detection device 27, It is detected by the second start detection device 27. Subsequently, a first jackpot lottery triggered by a detection signal from the first start detection device 25 or a second jackpot lottery triggered by a detection signal from the second start detection device 27 is started.

  Next, the characteristic part which concerns on the game of this embodiment is demonstrated. First, the first characteristic portion is provided with a plurality of unit special games that are repeatedly executed in a special game and a first unit special game and a second unit special game that is more advantageous to the player than the first unit special game. That is. That is, the special game execution determining means 131 described later determines that the first unit special game is a unit special game executed in the special game when the first jackpot lottery is won and the second jackpot lottery. When the jackpot is won, the second unit special game that is more advantageous to the player than the first unit special game is determined as the unit special game executed in the special game.

  Subsequently, a first example of the first and second unit special games will be described. In the first unit special game, the normally closed grand prize opening 15 is opened for 20 seconds or until 10 game balls are won, and each game ball that has won the grand prize opening 15 during this period is opened. The player is given 10 prize balls. That is, in the first unit special game, a maximum of 100 (10 × 10) prize balls are awarded to the player. On the other hand, in the second unit special game, the big prize opening 15 is opened for 30 seconds or until 15 game balls are won, and 10 game balls are won for each game ball won in the big prize opening 15 during this period. Give the player a prize ball. That is, in the second unit special game, a maximum of 150 (15 × 10) prize balls are awarded to the player. Thus, since the second unit special game can receive a maximum of 150 prize balls, it is more advantageous for the player than the first unit special game that can receive a maximum of 100 prize balls.

  In the first example described above, there is no time limit for opening the special winning opening 15 (20 seconds for the first unit special game, 30 seconds for the second unit special game), and the first unit. In the special game, 10 game balls are awarded to the grand prize opening 15, and in the second unit special game, 15 game balls are awarded to the big prize opening 15, and the prize is awarded while the grand prize opening 15 is open. For each game ball, 10 prize balls may be given to the player.

  Alternatively, there is no restriction on the number of game balls that can be won in the big prize opening 15 (10 balls in the first unit special game, 15 balls in the second unit special game), and the big prize slot 15 in the first unit special game. Is opened for 20 seconds, and in the second unit special game, the grand prize opening 15 is opened for 30 seconds, and 10 prize balls are awarded for each game ball won while the big prize opening 15 is open. It may be given to the player. That is, the second unit special game is more advantageous to the player than the first unit special game because the time for which the big prize opening 15 is opened is longer than that of the first unit special game.

  Next, a second example of the first and second unit special games will be described. In the first unit special game, as in the first unit special game in the first example, for example, the grand prize opening 15 is opened for 20 seconds or until 10 game balls are won, Since the player is given 10 prize balls for each game ball won in the big prize opening 15, the player can receive a maximum of 100 (10 × 10) prize balls. On the other hand, in the second unit special game, the big prize opening 15 is opened under the same conditions as the first unit special game (for example, until either of 20 seconds or 10 game balls wins) Each game ball won in the winning opening 15 is awarded 15 award balls more than the number of the first unit special game award balls (10 balls), so that the player can receive a maximum of 150 (10 × 15) prize balls. Can receive. Thus, since the second unit special game can receive a maximum of 150 prize balls, it is more advantageous for the player than the first unit special game that can receive a maximum of 100 prize balls.

  In this way, the second unit special game is a game that is more advantageous for the player than the first unit special game, and winning the jackpot in the second jackpot lottery wins the jackpot in the first jackpot lottery. Since the player can obtain an advantageous game, it is possible to effectively prevent the player from stopping the launch of the game ball while the symbol is changing. In addition, by providing a plurality of unit special games executed in a special game as the first unit special game or the second unit special game, the frequency of winning a big hit while maintaining the profit return rate to the player, It is also possible to increase the number of ball game machines.

  Furthermore, in the present embodiment, the jackpot determination means 115 described later includes a plurality of random number tables (random number table 1 and random number table 2), and the winning probability of jackpot between the random number table 1 and the random number table 2 can be made different. . That is, the winning probability of the second jackpot lottery based on the random number table 2 may be different from the winning probability of the first jackpot lottery based on the random number table 1.

  For example, if the jackpot winning probability in the second jackpot lottery is made higher than the jackpot winning probability in the first jackpot lottery, the second jackpot lotter will be more advantageous for the player than the first jackpot lottery. As a result, it is possible to more effectively prevent the player from stopping the launch of the game ball during the symbol change.

  On the other hand, if the winning probability of the jackpot in the second jackpot lottery is made lower than the winning probability of the jackpot in the first jackpot lottery, the winning probability in the first jackpot lottery can be increased. As a result, it is possible to further increase the frequency of winning the jackpot while maintaining the profit return rate to the player.

  Next, the 2nd characteristic part which concerns on the game of this embodiment is demonstrated. The ball game machine 1 according to the present embodiment has three effect modes (hereinafter referred to as “effect mode A”, “effect mode B”, and “effect mode C”, respectively) having different symbol variation times. The effect mode A is the effect mode having the longest symbol variation time of, for example, 30 seconds, among the three effect modes, and the player receives five or more game balls during the symbol variation time of 30 seconds. It is easy to get 12 to win. When four game balls are stored during the symbol variation time, the shutter 29 is opened as described above, and the game ball that has won the next prize-winning unit 12 is guided to the second path 26 to detect the second start. Since it passes through the device 27, the second jackpot lottery is performed. When the big jackpot is won in the second jackpot lottery, the second unit special game is repeatedly executed for a predetermined number of rounds (up to 15 rounds) as described above, so the presentation mode A is an advantageous mode advantageous to the player. .

  On the other hand, the effect mode B is an effect mode in which the symbol variation time is, for example, 15 seconds, which is shorter than the effect mode A, and causes the specific winning unit 12 to win five or more game balls during the symbol variation time of 15 seconds. It is possible but not easy. The effect mode C is the effect mode in which the symbol variation time is, for example, 7 seconds, which is the shortest among the three effect modes, and five or more game balls are assigned to the specific winning portion 12 during the symbol variation time of 7 seconds. It is very difficult to win a prize. As described above, the ball game machine 1 according to the present embodiment has three effect modes A, B, and C having different symbol variation times, and switching to each effect mode is performed by effect mode lottery based on predetermined conditions. Done. The effect mode lottery will be described in the jackpot determination process described later.

  Next, the determination result of whether or not the big hit is based on the first or second jackpot lottery mentioned above is a symbol pattern (a jackpot symbol pattern or a missed symbol pattern) to be displayed after the symbols are variably displayed on the symbol display device 11. The player is notified by voice output from the voice output unit 11a (see FIG. 5). The symbol pattern does not simply notify the player of the determination result of whether or not it is a big hit, but also includes an effect pattern such as reach, super reach, etc. It gives a lot of interest.

  When a jackpot symbol (for example, a symbol of a specific slot of “7”, “7”, “7”) is stopped and displayed on the symbol display device 11, the jackpot is won and a special game is subsequently started. In other words, the first unit special game is started when the jackpot is won in the first jackpot lottery, and the second unit special game is started when the jackpot is won in the second jackpot lottery. As described above, after the normally closed big prize opening 15 is opened and opened, the big prize opening 15 is temporarily closed, for example, when a predetermined number of game balls are won or a predetermined time elapses. Is done. Then, a predetermined number of prize balls set in each of the first or second unit special games are paid out to the player for each game ball won while the grand prize opening 15 is opened. Furthermore, if there is a prize in the V zone provided inside the big prize opening 15 while the big prize opening 15 is open, the big prize opening 15 is once closed and then opened again. Such opening and closing of the big prize opening 15 are repeatedly executed for a predetermined number of rounds. On the other hand, when the first or second unit special game is repeatedly executed for a predetermined number of rounds, or when there is no winning in the V zone while the special winning opening 15 is opened, the special game is ended.

  Next, main game control of the ball game machine 1 according to the embodiment of the present invention will be described with reference to FIG.

Hereinafter, each component of the game control unit 100 will be described.

  The game control means 100 includes special game determination means 110, game effect control means 120, and special game control means 130.

  The special game determination unit 110 includes a normal symbol winning determination unit 111, an enlargement device operation control unit 112, a shutter operation control unit 113, a rotating body operation control unit 114, a jackpot determination unit 115, and a game effect determination unit 116. , Symbol variation time determination means 117.

  The normal symbol winning determination means 111 determines whether or not the game ball has passed the operation gate 17 based on the detection signal from the operation gate passage detection device 17a, and displays the normal symbol on the normal symbol display unit 3 in a variable manner. When it is determined that the normal symbol is won, the lamp of the normal symbol display unit 3 is turned on in a predetermined state.

  The magnifying device operation control means 112 controls the magnifying device drive source 13a of the specific winning unit 12 to operate the magnifying device 13. That is, when the normal symbol winning determination means 111 determines that the normal symbol is won, the enlargement device operation control means 112 controls the enlargement device drive source 13a to operate the enlargement devices 13 and 13.

  The shutter operation control means 113 determines whether or not a predetermined number (four) of game balls are stored based on a stop detection signal from the storage ball detection device 22, and controls the shutter drive source 29a to control the shutter 29. Open and close.

  The rotating body operation control means 114 controls the rotating body drive source 30a to rotate the rotating body 30 clockwise or counterclockwise based on the respective symbol variation times, or stop the rotation, and further rotate the rotating body. The rotation speed of 30 is changed.

  The jackpot determination means 115 includes a start detection determination means 115a, a random number lottery means 115b, and a jackpot determination means 115c. The start detection determination unit 115a determines which start detection device the game ball has passed through based on a detection signal from the first start detection device 25 or the second start detection device 27. The random number lottery means 115b performs the first jackpot lottery or the second jackpot lottery based on the determination of the start detection judging means 115a. That is, when the game ball passes the first start detection device 25, the first big hit lottery using the random number table 1 is performed, and when the game ball passes the second start detection device 27, the random number table 2 is stored. The second jackpot lottery used is drawn. The jackpot determining means 115c determines whether or not the jackpot winning is based on the result of the first jackpot lottery or the second jackpot lottery.

  The game effect determining means 116 includes effect data storage means 116a, symbol pattern determining means 116b, and effect pattern determining means 116c. The effect data storage means 116 a stores a plurality of symbol patterns and effect pattern effect data displayed on the symbol display device 11. The symbol pattern determining unit 116b determines a symbol pattern for jackpot or miss to be displayed on the symbol display device 11 based on the determination by the jackpot determining unit 115c. The effect pattern determination means 116c determines the effect pattern of big hit or miss based on the determination of the jackpot determination means 115c.

  The symbol variation time determination unit 117 includes a specific symbol determination unit 117a, an effect mode lottery unit 117b, and an effect mode determination unit 117c. The specific symbol determination unit 117a determines whether or not the stop symbol determined by the symbol pattern determination unit 116a is a specific symbol. The effect mode lottery means 117b performs the effect mode (symbol variation time) lottery when the specific symbol determining means 117a determines that the symbol is a specific symbol. The production mode lottery is executed by selecting either the lottery table 1 or the lottery table 2 according to the type of the specific symbol as will be described later. The effect mode determining means 117c determines the effect mode (symbol variation time) based on the result of the effect mode lottery.

  The game effect control means 120 includes a symbol display control means 121 and a voice output control means 122, and controls the symbol display device 11 and the voice output unit 11a to provide the determined symbol pattern and effect pattern to the player.

  The special game control unit 130 includes a special game execution determination unit 131, a cycle game execution unit 132, a continuation determination unit 133, and a special game end determination unit 134. The special game execution determination unit 131 determines execution of the special game based on the jackpot determination result by the jackpot determination unit 115c, and further determines a unit special game (first or second unit special game) to be executed in the special game. To do. The cycle game execution means 132 executes the unit special game of either the first or second unit special game determined by the special game execution determination means 131. The continuation determination unit 133 determines whether or not to continue the unit special game. The special game end determination means 134 determines whether or not to end the special game.

  Next, with reference to the flowcharts of FIGS. 6 to 10, the flow of a series of processes from when the game ball is won to the specific winning unit 12 until the special game is executed and ended in the bullet ball gaming machine 1 will be described. To do.

  First, as shown in FIG. 6, the series of processes is roughly constituted by a jackpot determination process (step S1) and a special game control process (step S2). The jackpot determination process (step S1) is a process for determining whether or not the jackpot is based on the acquired random number, and the special game control process (step S4) is a case where execution of the special game (jackpot) is determined. This is a control process that causes a special game to be executed.

  7 and 8 show a flow of the jackpot determination process in step S1. That is, the jackpot determination process (step S1) is performed by a series of processes (steps S11 to S19) shown in FIG. 7, and then proceeds to the symbol variation process (step S20) shown in FIG. FIG. 9 shows a flow of the symbol variation time determination process in step S40.

  The flow of the jackpot determination process (step S1) will be sequentially described. First, it is determined whether or not the game ball has won the specific winning portion 12 (step S11). That is, if the game ball is detected by the prize ball detection device 12a, it is determined that the game ball has won the specific prize unit 12.

  If it is determined in step S11 that there is a prize, 4 is added to the prize ball counter in order to give a predetermined number (for example, 4) of prize balls to the player (step S12). Subsequently, the shutter operation control means 113 opens and closes the shutter 29 (step S13). For example, when a stop detection signal is transmitted from the storage ball detection device 22, the shutter operation control means 113 controls the shutter drive source 29a to open the shutter 29 (see FIG. 4).

  Next, it is determined by the start detection determination means 115a whether or not the game ball has passed through the first start detection device 25 (step S14). That is, in a state where the shutter 29 is closed (FIGS. 2 and 3), the game ball is first in the first path (lower stage) 23, the rotating body 30 (ball receiving portion 31), and the first path (upper stage) 24. It is guided by the start detection device 25 and passes through the first start detection device 25. When the shutter 29 is closed (FIG. 4), the game ball is guided to the second start detection device 27 by the second path 26 and passes through the second start detection device 27.

  When the start detection determining means 115a determines the passage of the first start detection device 25 in step S14, the start detection determining means 115a turns on the first lottery flag (step S15), and the random number lottery means 115b is the random number table 1 described above. A random number is obtained from the data (step S16). On the other hand, when the start detection determination means 115a determines the passage of the second start detection device 27, the start detection determination means 115a turns on the second lottery flag (step S17), and the random number lottery means 115b receives the random number table described above. A random number is acquired from 2 (step S18).

  When the random number is acquired by the random number lottery means 115b, the symbol display device 11 determines whether to allow symbol variation for symbol variation (step S19). That is, when the symbol is currently fluctuating, the symbol variation prohibition flag is turned on as described later (step S51), and the symbol variation prohibition state is set. Therefore, before shifting to the symbol variation process of step S20, it is determined whether or not it is in the symbol variation prohibited state. If the symbol variation prohibition flag is not turned on, symbol variation is permitted, and the symbol variation process (step S20) shown in FIG. 8 is started.

  In the symbol variation process (step S20) shown in FIG. 8, the jackpot determining means 115c determines whether or not the random number acquired in step S16 or step S18 is a jackpot (step S21). When it is determined that the jackpot is successful, the jackpot flag is turned on (step S22), the jackpot symbol pattern is determined by the symbol pattern determining means 116a (step S23), and the jackpot effect pattern is determined by the effect pattern determining means 116b (step S24). ).

  If it is determined in step S21 that it is not a big hit (out), the out flag is turned on (step S30), and then the effect mode flag is read out (step S30). As described above, in the present embodiment, three effect modes, effect modes A, B, and C having different symbol variation times are provided, and the current effect mode is read out.

  First, it is determined whether the production mode flag A is turned on (step S32). When the production mode flag A is confirmed, the design pattern determining means 116a corresponds to the production mode A (design variation time 30 seconds). The off symbol pattern is determined (step S34), and the off effect pattern corresponding to the effect mode A (the symbol variation time 30 seconds) is determined by the effect pattern determining means 116b (step S37). If the effect mode flag A is not confirmed, it is next determined whether the effect mode flag B is turned on (step S33). When the effect mode flag B is confirmed, the symbol pattern determining means 116a determines an out symbol pattern corresponding to the effect mode B (the symbol variation time 15 seconds) (step S35), and the effect pattern determining means 116b determines the effect mode B ( The off-line production pattern corresponding to the symbol variation time of 15 seconds is determined (step S38). If the effect mode flag B is not confirmed, the symbol pattern determining means 116a determines an out symbol pattern corresponding to the effect mode C (symbol variation time 7 seconds) (step S36), and the effect pattern determining means 116b determines the effect mode. An off effect pattern corresponding to C (design variation time of 7 seconds) is determined (step S39).

  When the off effect pattern corresponding to each effect mode is determined in steps S37, S38, and S39, the process proceeds to the symbol variation time determination process (step S40). Next, the flow of the symbol variation time determination process (step S40) will be described with reference to FIG.

  First, the specific symbol determination unit 117a determines whether or not the stop symbol of the off symbol pattern determined in the processes of steps S37, S38, and S39 corresponds to the specific symbol (step S41). The specific symbol is, for example, an arbitrary number of numbers selected in advance such as “1”, “2”, “3”, and a plurality of specific symbols are designated. When the stop symbol of the off symbol pattern corresponds to the plurality of specific symbols, the process proceeds to the effect mode lottery described below, and when the symbol does not correspond to the specific symbol, the symbol variation time determination process (step S40) ends.

  If it corresponds to the specific symbol, the specific symbol determination means 117a further determines whether or not the stop symbol of the off symbol pattern corresponds to the specific mode A symbol (step S42). The specific mode A symbol is a symbol selected in advance as a specific mode A symbol such as “7”, “7”, and “6” among a plurality of specified symbols.

  When it corresponds to the specific mode A symbol, the effect mode lottery means 117b executes the effect mode lottery based on the lottery table 1 (step S43), and when it does not correspond to the specific mode A symbol, the effect mode lottery means 117b performs the lottery table. In step S44, the effect mode lottery is executed. Here, the lottery table 1 is, for example, a lottery table that is easy to win the effect mode A set to win the effect mode A with a probability of 3/4. The lottery table 2 is, for example, a lottery table that is set to win the presentation modes A, B, and C with a probability of one third.

  Next, the result of the effect mode lottery in steps S43 and S44 is determined by the effect mode determining means 117c. First, it is determined whether or not the effect mode A has been won (step S45). If the effect mode A is won, the effect mode flag A is set (step S47). Subsequently, when the effect mode A is not won, it is determined whether or not the effect mode B is won (step S46). When the effect mode B is won, the effect mode flag B is set (step S48). ). If the effect mode B is not won, the effect mode flag C is set (step S49). The symbol variation time determination process (step S40) ends when any of the effect mode flags A, B, and C is set by the processes of steps S46, S47, and S48.

  When the symbol variation time determination process (step S40) is finished, the jackpot symbol pattern determined in step S23, the losing symbol pattern determined in steps S34 to 36, the jackpot effect pattern determined in step S24, and step S37. Each command of the off effect pattern determined in .about.39 is transmitted (step S50). Subsequently, the symbol variation prohibition flag is turned on, and the symbol variation prohibition state is set (step S51). Then, the symbol variation timer is set (step S52), and the jackpot determination process (step S1) shown in FIGS. 7 and 8 ends, and a game effect based on the determined jackpot effect pattern or the missed effect pattern is given to the player. Provided.

  Then, the special game execution determination unit 131 determines execution of the special game based on the jackpot determination result by the jackpot determination unit 115c. That is, the presence / absence of the jackpot flag turned on in step S22 is confirmed. If the jackpot flag is turned on, the process proceeds to a special game control process (step S2).

  Next, the special game control process (step S2) will be described based on the flowchart of FIG. First, the special game execution determination means 131 confirms that the jackpot flag is turned on (step S201). If the jackpot flag is turned on, the lottery flag is subsequently read (step S202). Reading the lottery flag is a process of confirming the first or second lottery flag set in step S15 or step S17 described above. Next, the unit special game to be executed based on the turned-on first or second lottery flag is determined by the game execution determination means 131 (step S203). That is, if the first lottery flag is turned on, the first unit special game is determined as a unit special game executed in the special game, and if the second lottery flag is turned on, the second unit special game is determined. Is determined as a unit special game to be executed in the special game.

  When the unit special game to be executed is determined, the determined unit special game is then started (step S204). That is, the special winning opening drive source 14a of the attacker unit 14 is controlled, and the opening of the entrance of the special winning opening 15 is started. Then, the special game control means 130 opens the entrance of the special prize opening 15 and then a predetermined number of balls (for example, 10 balls for the first unit special game, 15 balls for the second unit special game). Depending on whether or not a game ball has won or a predetermined time (for example, 20 seconds for the first unit special game, 30 seconds for the second unit special game) has passed (step S205), The entrance of the big prize opening 15 is once closed, and the first or second unit special game is ended (step S206). Thus, the first or second unit special game is repeatedly executed for a predetermined number of rounds (for example, a maximum of 15 rounds).

  Subsequently, the special game end determination means 134 determines whether or not the round is the final round (step S207), and the special game ends when the round is the final round. On the other hand, when the round is not the final round in step S207, the process returns to step S204 to start a subsequent round.

  Although one embodiment of the present invention has been described above, according to the present invention, the first jackpot lottery is performed for each detection by the first start detection device 25 (first detection means), and the second start detection device. When the second jackpot lottery is performed for each detection by the player 27 (second detection means) and the jackpot is won in the second jackpot lottery, the second unit special game that is more advantageous to the player than the first unit special game Therefore, it is possible to effectively prevent the player from stopping the launch of the game ball during the symbol change, and it is possible to prevent a reduction in the operation rate of the ball game machine.

  The special game executing means executes the first unit special game when winning the jackpot in the first jackpot lottery, and executes the second unit special game when winning the jackpot in the second jackpot lottery. Therefore, it is possible to increase the frequency of winning the jackpot while maintaining the profit return rate to the player, and to provide more interest to the player.

  In addition, according to the present invention, including the effect modes A, B, and C, the design variation time of the effect mode A is longer than the design variation time of the effect modes B and C. More game balls than modes B and C can be won in the winning portion, and the detection of the game balls by the second detection means is facilitated. As a result, in the production mode A, it is possible to increase the frequency of winning the jackpot in the second jackpot lottery over the production modes B and C, and to make the production mode A more advantageous for the player than the production modes B and C. Become. As described above, by selecting a plurality of effect modes having different symbol variation times, it is possible to easily change the frequency of winning a jackpot in the first or second jackpot lottery.

  In addition, according to the present invention, the identification information of each effect data stored in the effect data storage means 116a can be displayed on the variable display device (symbol display device 11). It is also possible to change the rate at which the game ball is detected and the rate at which the second start detection device 27 detects the game ball based on the effect modes A, B, and C selected from the effect data. As a result, it is possible to change the frequency of winning the jackpot in the first or second jackpot lottery by selecting the production mode.

  Further, according to the present invention, the jackpot winning probability in the first jackpot lottery is made different from the jackpot winning probability in the second jackpot lottery. As a result, it is possible to make the second jackpot lottery more advantageous for the player by making the jackpot winning probability in the second jackpot lottery higher than the jackpot winning probability in the first jackpot lottery. . Alternatively, if the winning probability of the jackpot in the second jackpot lottery is lower than the winning probability of the jackpot in the first jackpot lottery, it is possible to further increase the frequency of winning the jackpot while maintaining the profit return rate to the player It is.

  Note that the scope of the present invention is not limited to the above-described embodiments, and can be applied to various other embodiments as long as they do not contradict the description of the claims. For example, in the embodiment of the present invention, the game ball storage device 20 has been described as a suitable example of the storage unit that stores up to a predetermined number of game balls won in the winning unit (specific winning unit 12). The invention is not limited to this, and any means may be used as long as it can store up to a predetermined number of game balls won in the winning portion.

  In the present embodiment, the production modes A, B, and C having different symbol variation times have been described. However, if there is at least the first production mode and the second production mode, the other production modes are available. May be.

  In the present embodiment, the special game is executed when the first or second unit special game is repeatedly executed for a predetermined number of rounds, or when there is no winning in the V zone while the special winning opening 15 is opened. Although it ends, the aspect of the special game is not limited to this. For example, the first or second unit special game may be repeatedly executed for a predetermined number of rounds regardless of whether or not the V zone is won while the grand prize opening 15 is opened, or the first unit The predetermined number of rounds in the special game may be different from the predetermined number of rounds in the second unit special game.

  The present invention can be applied not only to a so-called pachinko machine but also to other ball game machines such as an arrangement ball as long as it is a ball game machine using game balls.
