Abstract

PROBLEM TO BE SOLVED: To provide a pinball game machine capable of bringing a specified game state after a jackpot game into a pseudo winning ball increased state.SOLUTION: A pinball game machine includes the first start hole 12 for carrying out the first special pattern lottery in a winning prize of a game ball as an opportunity, an ordinary pattern operation gate 15 for carrying out an ordinary pattern lottery in passing of the game ball as an opportunity, the second start hole (motor-driven tulip) 13 for carrying out the second special pattern lottery in the winning prize of the game ball as an opportunity, and a large prize hole 16 operated openingly and closingly based on lottery results in the first and second special pattern lotteries. When hit with a jackpot in the first special pattern lottery based on the winning to the first start hole 12, a variation display time of the ordinary pattern under a time-shortened game given after the jackpot game is more shortened than that in an ordinary game time, to enhance a chance for the second special pattern lottery.

Description

  The present invention relates to a ball game machine that is installed and used in a game hall such as a pachinko parlor, and in particular, a ball game in which a big win and a small win are determined by a special symbol lottery performed when a game ball is won. Related to the machine.

  Some ball game machines have a special symbol lottery when a game ball is won at a specific starting point, and when the lottery results are a big hit, for example, up to 15 rounds of big prize holes called attackers There are models that open up to 10 winnings per round as the upper limit, and when the lottery result is a small win, the big winning opening is opened once for 1.8 seconds, for example. In such a ball game machine, a large number of balls can be obtained only when the jackpot is reached, and the jackpot is generally installed to enhance the effect of the game. , It is not possible to increase the number of balls by small hits.

  Therefore, conventionally, there is a first start opening for performing the first special symbol lottery when the game ball is won, and a second start opening for performing the second special symbol lottery when the game ball is won. When the deviation of the first special symbol lottery based on the winning at the first starting opening reaches a predetermined number of times (for example, 1000 times), the winning rate at the second starting opening is set by changing the opening / closing operation of the electric accessory. A ball game machine that increases the probability of winning a small winning of the second special symbol lottery based on winning at the second starting opening, and increases the number of balls by opening the large winning opening based on this small winning Has been proposed (see, for example, Patent Document 1). According to the ball game machine configured in this way, when the first special symbol lottery reaches a predetermined number of times, it is possible to increase the number of balls by increasing the small win winning probability of the second special symbol lottery. Therefore, the labor consumed by the player until the predetermined number of times is reached can be rewarded.

JP 2006-25834 A

  However, in the conventional ball and ball game machine disclosed in Patent Document 1, a privilege to increase the winning probability of a small hit is given only when the first special symbol lottery reaches a predetermined number of times. Therefore, there is a problem in that a great unfairness occurs between a player who has finished a game before reaching a predetermined number of times and a player who has subsequently played a predetermined number of times. Further, in a model having a jackpot probability in a normal state of, for example, about 1/300, such a predetermined number of times is about 1000 times referred to as a so-called “large ball” and is a number of times that occurs very rarely. In a normal gaming state, only a big win can be obtained, and there is room for improvement in terms of enhancing the fun of the game.

  The present invention has been made in view of the situation of the prior art as described above, and an object of the present invention is to provide a ball game machine that can make a pseudo game increase state during a specific game after a jackpot game. There is.

  In order to achieve the above-described object, the ball game machine of the present invention is triggered by the fact that the game ball has passed the first start opening for performing the first special symbol lottery when the game ball is won. A normal symbol actuating gate for starting a normal symbol variation display by performing a normal symbol lottery, and a movable piece that opens and closes based on the lottery result of the normal symbol lottery, and the second when the game ball is won A second start opening for performing the special symbol lottery of the first and second special symbol lottery that opens and closes based on the lottery results of the first and second special symbol lottery, the first and second special symbol lottery A lottery including a jackpot, a jackpot, and a loser with different opening styles of the big prize opening is performed, and a bonus winning prize of the second special symbol lottery is selected with respect to a probability of winning the bonus of the first special symbol lottery If the probability is set to be high In addition, the second special symbol lottery is set to perform a lottery to win with a higher probability of jackpot and loser than the big win, and if the first or second special symbol lottery is won The normal game state is selectively shifted to the specific game state, and the change display time of the normal symbol during the specific game is made shorter than that in the normal game.

  In the case of a ball game machine configured in this way, if a big win is won in the lottery result of the first or second special symbol lottery based on the winning at the first or second starting port, it is selectively selected from the normal gaming state. The transition to the specific gaming state is made, and the fluctuation display time of the normal symbol in the specific game is made shorter than that in the normal game, and the lottery opportunity of the second special symbol lottery in the specific gaming state is larger than that in the normal gaming state. As a result, during the specific game, it is possible to achieve a pseudo-increase state by acquiring the ball by the small hit itself.

  In the above configuration, the first start opening and the second start opening are arranged at different positions in the game area, and the normal symbol operation gate and the big prize opening are located in the vertical direction of the game area across the second start opening. If they are arranged in a distributed manner, for example, during a normal game where there are few chances for winning at the second starting opening, the game ball is launched aiming at the first starting opening and the winning opportunity at the second starting opening is increased. During a specific game, it is possible to play a game in which the target position of the game ball is selected according to the game state, such as firing a game ball aiming at the normal symbol operating gate.

  The bullet ball game machine of the present invention has a first start opening for performing a first special symbol lottery when the game ball is won, and a normal symbol operation gate for performing a normal symbol lottery when the game ball has passed. And a second start opening for performing the second special symbol lottery in response to the winning of the game ball, and a large winning opening that opens and closes based on the lottery results of the first and second special symbol lottery, If you win a jackpot in the lottery result of the first or second special symbol lottery based on the winning at the first or second starting opening, you can selectively shift from the normal gaming state to the specific gaming state, during this specific game Since the fluctuation display time of the normal symbol of the game is shorter than that in the normal game, and the lottery opportunity of the second special symbol lottery is increased, it is possible to obtain a bounty by small hits during a specific game and to simulate The ball can be increased, and therefore only a jackpot It is possible to enhance the interest of the game created a new payout increasing function with small win without.

1 is a front view of a ball game machine according to an embodiment of the present invention. It is explanatory drawing which shows the probability of the 1st and 2nd special symbol lottery at the time of a normal game. It is a flowchart which shows the control process of a normal symbol lottery. It is explanatory drawing which shows the relationship between a some gaming state and the probability of the 1st and 2nd special symbol lottery.

  FIG. 1 is a front view of a ball game machine according to an embodiment of the present invention, and FIG. 2 is a drawing of first and second special symbol lotteries in a normal game. FIG. 3 is a flowchart showing control processing for normal symbol lottery.

  As shown in FIG. 1, a bullet ball gaming machine 1 according to this embodiment includes a machine frame 2 installed in an island facility of a game hall, and a front frame 3 attached to the machine frame 2 so as to be openable and closable. A game board 4 housed and held in the front frame 3, a glass frame 5 attached to the front surface of the front frame 3 so as to be openable and closable, and a front board 6 disposed below the front frame 3, A firing handle 7 attached to the front board 6 is provided.

  The game board 4 has a game area 9 surrounded by guide rails 8 and the like. When the shooting handle 7 is rotated at an arbitrary angle by a manual operation of the player, the game board 4 is directed from the shooting device (not shown) to the game area 9. A game ball is launched. Near the center of the game area 9, a symbol display device 10 made of a liquid crystal panel (LCD) or the like is disposed, and a normal symbol display portion 11 made of an LED or the like is disposed in the lower right corner of the game board 4. Yes. Below the symbol display device 10, there is a first start port 12 that executes the first special symbol lottery when the game ball wins and starts the variable display of the first special symbol on the symbol display device 10. It is arranged. On the right side of the symbol display device 10, a second special symbol lottery is executed in response to the winning of a game ball, and the symbol display device 10 starts a variable display of the second special symbol. A mouth 13 is provided. The second start port 13 is configured as an electric tulip having a pair of movable pieces 13a that can be opened and closed, and a plurality of obstacle nails 14 are disposed above the movable piece 13a. When the movable piece 13a is closed by the obstacle nail 14, the game ball is prevented from winning a prize at the second starting port 13, and only when the movable piece 13a is opened, the gaming ball is not supplied to the second starting port 13. Winning is permitted.

  Above the second start port 13, a normal symbol operation gate 15 is arranged to execute the normal symbol lottery when the game ball has passed and to start the normal symbol variation display on the normal symbol display unit 11. Yes. Although details will be described later, when the lottery result of the normal symbol lottery is a win, the fluctuation display of the normal symbol display unit 11 is stopped at a specific symbol, and the movable piece 13a of the second start port 13 has a predetermined opening time. And it is designed to open with the number of releases. In addition, a big prize opening 16 called an attacker is arranged below the second start opening 13, and as will be described later, this special prize opening 16 is based on the lottery results of the first and second special symbol lotteries. Open and close. The game area 9 is provided with a general winning port (not shown) in addition to the first and second starting ports 12 and 13 and the big winning port 16, and a game that has not won any starting port or winning port. The ball is discharged to the back side of the game board 4 from an out port 17 provided at the lowermost end of the game area 9.

  When a game ball passes through the normal symbol operation gate 15 during a normal game, the normal symbol lottery performs a hit determination with a low probability of, for example, a normal symbol variation time of 30 seconds and a hit probability of 1/50, and the lottery result is hit. In this case, the normal symbol display unit 11 stops the variable display at a specific symbol, and opens the movable piece 13a of the second starting port 13 once, for example, for 0.5 seconds.

  In addition, when the game ball wins the first start port 12 or the second start port 13 during the normal game, the first and second special symbol lottery determines the big hit, the small hit and the loss with a preset probability, The special winning opening 16 is opened and closed based on the lottery result. Here, as shown in FIG. 2, the small win winning probability of the second special symbol lottery is set to be significantly higher than the small win winning probability of the first special symbol lottery. The jackpot probability of the special symbol lottery of 1 is set to 1/256, the probability of small hitting is set to 1/256, and the loss probability is set to 254/256, whereas the jackpot probability of the second special symbol lottery is set to 1/256, The small hit probability is set to 254/256, and the loss probability is set to 1/256. If the lottery result of the first or second special symbol lottery is a big hit, the variable display on the symbol display device 10 is stopped at a specific symbol, for example, “777”, and the big prize opening 16 is made a predetermined number of times. Only open operation. The big winning opening 16 is maintained in an open state until 30 seconds elapses for one opening or until 10 game balls are won, for example, and after repeating the opening operation 15 times, the jackpot ends. In addition, when the lottery result of the first or second special symbol lottery is a small win, the variable display on the symbol display device 10 is stopped at a specific symbol other than the big hit, for example, “123”, and the big prize opening 16 is opened once for 1.8 seconds, for example, and when the lottery result of the first or second special symbol lottery is lost, the closed state of the special winning opening 16 is maintained. However, as described above, the probability of opening the movable piece 13a by normal symbol lottery during normal gaming (the winning probability 1/50) is set low, and the obstacle nail 14 is disposed above the movable piece 13a. Therefore, the game ball rarely wins the second starting port 13 during the normal game.

  When the jackpot is won in the first or second special symbol lottery, a specific game state in which a privilege advantageous to the player is given after the jackpot game, for example, the variation display time of the special symbol or the normal symbol is shortened. It becomes a specific game state called “short-time game”. In addition, as long as the number of time savings in which the time-saving game is continued is within 100 times, it can be set to an arbitrary number such as 25 times, 50 times, and 100 times. At this time, when the game ball passes through the normal symbol operation gate 15 in the short game, the normal symbol lottery shortens the fluctuation time of the normal symbol from 30 seconds to 0.5 seconds, for example, and the hit probability is reduced from 1/50 to 49, for example. When the winning determination is made by changing to a high probability of / 50, and the lottery result is winning, the movable piece 13a of the second start port 13 is continuously opened twice for 2 seconds, for example.

  That is, as shown in the flowchart of FIG. 3, in the control process of the normal symbol lottery performed when the game ball passes, it is first determined whether or not the game ball has passed the normal symbol operation gate 15 (S- 100) When it is detected in S-100 that the game ball has passed the normal symbol operation gate 15, the game state at that time is determined (S-101). If it is determined in S-101 that the gaming state is a normal game, the process proceeds to S-102, and the normal symbol lottery is performed with a low probability that the variation time of the normal symbol is 30 seconds and the hit probability is 1/50. (S-103). If the lottery result of the normal symbol lottery is determined to be a win in S-103, the fluctuation display of the normal symbol display unit 11 is stopped at a specific symbol, and the movable piece 13a of the second start port 13 is held for 0.5 seconds. When the lottery result of the normal symbol lottery is determined to be lost in S-103, the movable piece 13a is kept closed without being opened.

  On the other hand, if it is determined in S-101 that the gaming state is a short-time game, the process proceeds to S-105, where the normal symbol lottery has a high probability that the variation time of the normal symbol is 0.5 seconds and the hit probability is 49/50. The hit determination is performed (S-106). If the lottery result of the normal symbol lottery is determined to be win in S-106, the fluctuation display of the normal symbol display unit 11 is stopped at a specific symbol, and the movable piece 13a of the second start port 13 is stopped for 2 seconds. If the lottery result of the normal symbol lottery is determined to be lost in S-106, the movable piece 13a is maintained in the closed state without performing the opening operation. As described above, the probability of opening the movable piece 13a by the normal symbol lottery during the short-time game is significantly higher than that in the normal game (the probability of hitting is greatly increased), and the opening mode of the movable piece 13a is more advantageous than that in the normal game. Therefore, the winning rate to the second start port 13 that was difficult to win in the normal game becomes very high in the short-time game.

  In the ball ball game machine 1 configured as described above, when a player rotates the launch handle 7 to an arbitrary angle, a game ball is launched from a launch device (not shown) toward the game area 9. The game ball is dropped in the game area 9 by its own weight, and the direction is changed by an obstacle nail or a windmill (not shown). In the process of falling, the game ball wins the first starting port 12 or passes through the normal symbol operation gate 15. Then, the game balls that have not won any start opening or winning opening are discharged from the out opening 17. At that time, the probability of opening the movable piece 13a by the normal symbol lottery during the normal game is set low, and even if the game ball passes the normal symbol operation gate 15, the second starting port 13 is hardly won. In a normal game, it is preferable to launch a game ball aiming at the left side of the center portion of the game area 9 and win the first starting port 12.

  In such a normal game, when the game ball wins the first start opening 12 and the lottery result of the first special symbol lottery performed as a trigger is a big win, the big winning opening 16 is given a predetermined number of times (for example, 15 times). For example, if the number of payout balls for a single winning of the big winning opening 16 is 15, for example, about 1700 balls can be obtained in the jackpot winning of the first special symbol lottery. When this jackpot is over, the gaming state shifts from the normal game to the short-time game, the fluctuation time of the normal symbol lottery is greatly shortened, and the winning probability is changed from the low probability to the high probability. Therefore, when the short time state is reached, the game ball is launched (right-handed) toward the right side of the center of the game area 9, so that the game ball is placed on the normal symbol operating gate 15 disposed on the upper right side of the game area 9. Is preferably passed.

  When the game ball passes through the normal symbol operation gate 15 in such a short game, the normal symbol lottery is executed with a high hit probability (for example, 49/50), and the lottery result is a win. Since the movable piece 13a of the second start port 13 is continuously opened twice for 2 seconds, the game ball falling on the right side of the game area 9 can be awarded to the second start port 13 at a high winning rate. Here, the winning probability of the second special symbol lottery performed upon winning the second start opening 13 is set to be very high (for example, 254/256), so the game ball is set to the second start opening. When winning 13 is achieved, most of the winnings become small hits and the large winning opening 16 is opened once for, for example, 1.8 seconds. As described above, when aiming right at the normal symbol operating gate 15 in the short-time game, the movable piece 13a of the second start port 13 disposed on the upstream side of the game ball dropping path is opened with high probability, Since the large winning opening 16 arranged on the downstream side also opens with a high probability, it is possible to expect a large number of winnings by repeatedly opening the large winning opening 16 with a small hit during a short-time game. For example, when it is calculated on the assumption that an average of two game balls are won in the big winning opening 16 per small game (30 payout balls), 750 when the set number of short times is 25. When the number of times and the number of working hours is 50 times, it is possible to expect 1500 pieces, and when the number of working hours is 100 times, 3000 balls can be expected to be obtained.

  In addition, when winning a jackpot in the second special symbol lottery at the time-short game, after the jackpot is over, it will shift to the time-saving state again, and the number of times (such as 100 times) set without winning the jackpot ) Is reached, after that time is finished shortly, the normal state is entered and the normal game is returned.

  As described above, the ball game machine 1 according to the present embodiment is configured so that the first start port 12 for performing the first special symbol lottery when the game ball is won and the game ball has passed. A normal symbol operating gate 15 that performs a normal symbol lottery when triggered, a second start opening (electric tulip) 13 that performs a second special symbol lottery when a game ball wins, and a first and second special symbol If the first prize lottery that is opened and closed based on the lottery result of the lottery and the first special symbol lottery based on the winning to the first start opening 12 is won, the time is given after this jackpot game. The probability of opening the movable piece 13a by the normal symbol lottery during the game is made higher than that in the normal game to increase the winning rate to the second starting port 13, and the second based on the winning to the second starting port is made. Special design lottery wins and has Since the lottery with a higher probability of winning the jackpot will be performed, it is possible to obtain a lottery with the jackpot itself during the short-time game and make a pseudo-ballistic increase state. It is possible to enhance the fun of the game by creating a new function to increase the number of hits by winning.

  In addition, the first start port 12 and the second start port 13 are arranged at different positions in the game area 9, and the normal symbol operation gate 15 and the big winning port 16 fall between the second start port 13 and the game ball falls. Since it is distributed in the upper and lower positions of the route, during a normal game where the winning rate to the second starting port 13 is low, the player hits the first starting port 12 to the left and wins the second starting port 13 When the game is short, during a short game, it is possible to play a game in which the target position of the game ball is selected in accordance with the game state, such as hitting the symbol actuating gate 15 to the right.

  In the above-described embodiment, the case where the number of time reductions after the jackpot by the first and second special symbol lottery is set constant (for example, 100 times) has been described, but the number of time reductions in the first special symbol lottery is set. You may make lottery to distribute to multiple types (for example, 25 times, 50 times, and 100 times), and in this way, change the expectation of the amount of winning ball according to the number of times after the lottery result. Can do. At that time, the number of times after the lottery result may be clearly indicated on the symbol display device 10 or the like. However, if the number of times shortened is not clearly indicated, it is possible to create an increased number of balls that will not continue until now. There is no new game can be realized.

  Also, in the above embodiment example, even if the big win is won by either the first special symbol lottery or the second special symbol lottery, a time-shortening function is given after the jackpot ends. Only when winning the symbol lottery jackpot, the time-saving function may be given, and when winning the big jackpot in the second special symbol lottery, the game may be shifted to the normal game after the jackpot and the time-saving function may not be given.

  Further, in the above embodiment example, the “short-time game” has been described as an example of the specific game state given after the jackpot game. However, this specific game state increases the jackpot winning probability of the first and second special symbol lotteries. A game state called “probability game” may be included.

  FIG. 4 shows the relationship between a plurality of gaming states (normal game, probability-changing game, and short-time game) including such a probability-changing game (hereinafter abbreviated as probability-changing game) and the probabilities of the first and second special symbol lotteries. It is explanatory drawing which shows. As shown in the figure, in the normal gaming state and the short-time gaming state, for example, the big hit probability of the first special symbol lottery is set to 1/200, the small hit probability is 1/200, and the loss probability is set to 198/200. On the other hand, the jackpot probability of the second special symbol lottery is set to 1/200, the jackpot probability is 197/200, and the loss probability is set to 2/200. In addition, when the game changes to the probability variation gaming state, the jackpot probabilities of the first and second special symbol lotteries increase from 1/200 to 2/200, respectively, and accordingly, the loss probability of the first special symbol lottery increases to 198. The loss probability of the second special symbol lottery is set to fall from 2/200 to 1/200, from / 200 to 197/200.

  In this way, in the ball game machine 1 equipped with the probability variation function, when the jackpot is won in the first special symbol lottery performed at the time of winning the first starting port 12 in the normal game, the jackpot is surely changed. Draw at the same time whether the jackpot or single hit. And if the single special jackpot is won in the first special symbol lottery, the game state shifts from the normal game to the short-time game after the jackpot ends, and the fluctuation time of the normal symbol lottery is greatly shortened and the probability of winning Is changed from a low probability to a high probability, it is possible to acquire a ball with a small hit itself during a short-time game and to increase the number of balls. In addition, when winning a promising jackpot in the first special symbol lottery, the gaming state shifts from a normal game to a probable gaming after the jackpot ends, and the jackpot probability of the first and second special symbol lottery will be the next jackpot In addition to being raised until winning, the variation time of the normal symbol lottery is greatly shortened, and the winning probability is changed from a low probability to a high probability. In this case, since there is no upper limit of the number of time reductions in the probability variation game, the number of balls will continue to increase due to the small hit until the big win is won during the probability variation game.

  If you win a jackpot in the second special symbol lottery during a probable game, you will draw a probabilistic jackpot and a single jackpot in the same way as the first special symbol lottery, and the gaming state after the jackpot ends based on the lottery result However, there is a transition to either probabilistic games or short-time games. However, after the jackpot in the second special symbol lottery is over, the probability variation function may not be given, and the game may be in a short-time gaming state, or the short-time count after the jackpot ends may be set to zero, or a short-time end may be set. It is also possible to realize a game rich in variety, such as performing a lottery to distribute (for example, 25 times, 50 times, 100 times).
