Description

  The present invention relates to a gaming machine used in a game hall such as a pachinko parlor.

  In recent pachinko machines, for example, as shown in Patent Document 1, a pair of movable pieces are provided at a start winning opening, and when a game ball passes through a passing winning opening called a through chucker. When winning the open lottery to be performed, the movable piece is released, and it becomes easy for the game ball to win the start winning opening. The result of the open lottery is displayed on, for example, a 7-segment display with 1-digit display. When “7” stops after the display of normal symbols is displayed on this display, the open lottery will be selected. Is lost. When a pachinko ball enters the starting prize slot in the game board, a random lottery using a random number is performed, and special symbols such as numbers and marks are variably displayed on an image display device such as a liquid crystal display. When the symbol is determined, the special symbols are stopped so that the symbols of the same type are aligned.

  When the same special symbol is displayed after winning the symbol change display, the winning mode is displayed after a certain period of time. In the winning mode, an open / close board (attacker) built in the game board surface is opened, and a large winning opening that is normally closed is exposed. When the big prize opening is exposed, most of the pachinko balls flowing down the game board face are in a state where it is easy to win. When the attacker opens and a certain time elapses, or when a certain number of pachinko balls enter the winning prize opening, the attacker temporarily closes (end of the first round). In the second and subsequent rounds, the attacker is similarly controlled to open and close, and for example, it is normal to be able to repeat up to the 15th round.

Some pachinko machines that shift to the hit mode as described above shift to the probability variation mode in which the winning probability of winning is higher than that in the normal mode. The probability variation mode is shifted to after completion of the hit mode when a combination of specific special symbols is prepared. When shifting to the probability variation mode, the player shifts to the hit mode again in a short period of time, so the player can acquire a large amount of pachinko balls. In the probability variation mode, the variation time of the normal symbol is shorter than in the normal mode. Furthermore, in the normal mode, the movable piece is released once for each winning lottery, whereas in the probability variation mode, it is released. The movable piece is released three times for each winning of the lottery. Thereby, in the probability variation mode, the winning rate of the game balls at the start winning opening becomes higher than in the normal mode, so that it is easy to win again and it is possible to play the game while suppressing the decrease of the game balls on hand.

  However, in the above pachinko machines, the probability of winning in the probability variation mode is high, but there are cases where the winning period is not long and the game in the probability variation mode changes from the normal mode. There were times when there was no redundancy. In order to solve this, it is conceivable that the win probability is increased and the period of the probability variation mode is likely to be shortened. However, if the win probability is too high, the player's gambling will be jealous. The soundness of the pachinko machine may be lost.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine that can eliminate the redundancy of the game in the probability variation mode without encouraging the player's happiness.

  In order to achieve the above object, the gaming machine according to claim 1 includes a winning opening in which a pair of movable pieces open and close to change a winning rate of a game ball, and determines whether or not to open the movable piece. An open lottery is performed when a game ball passes through a passing prize opening, and the result of the open lottery is displayed by displaying a variable display of the symbol, and when the open lottery is won, the movable piece is displayed after the variable display Is released and the winning lottery executed in the normal mode wins the winning mode, the winning mode becomes more advantageous to the player than the normal mode, and the winning probability than the normal mode after the winning mode ends In a game machine that shifts to a probability variation mode in which the rate increases, in the probability variation mode, the variation time from the start of variation of the symbol to the end of variation is longer than in the normal mode, and Those with an open control means for opening and closing the movable piece as opening time until closing is increased from the open pieces.

  The first opening control pattern in which the symbol variation time is longer than that in the normal mode and the movable piece is released longer, and the symbol variation time is shorter than that in the normal mode. Is set to be longer than the normal mode and shorter than the first release control pattern, and in the probability variation mode, either the first release control pattern or the second release control pattern is executed. It is preferable that the kana is determined by opening control pattern selection lottery.

  Moreover, it is preferable that the probability variation mode is ended when the total opening time of the movable pieces reaches a predetermined time.

  According to the present invention, in the probability variation mode, the movable piece is opened and closed so that the variation time of the symbol is longer than that in the normal mode and the opening time of the movable piece is longer. By stopping the ball to stop firing, it becomes possible to increase the number of game balls, and it is possible to eliminate the redundancy of the game during the probability variation mode. Then, it is not necessary to increase the winning probability so that the period of the probability variation mode is shortened, and it is possible to prevent the player's enthusiasm.

  In addition, since the opening / closing pattern of the movable piece is determined by lottery, the games in the probability variation mode become diverse, and the interest in games in the probability variation mode can be enhanced.

  The probability variation mode ends when the total opening time of the movable pieces reaches a predetermined time, so that even if the opening control pattern changes, the winning rate of the game ball (the game ball was continuously fired) The probability that the game ball will win in this case can be made constant.

  In FIG. 1, the pachinko machine 10 includes a game board 10a. A game area 11 is formed on the front surface of the game board 10a, and a game ball launched in response to a player's launch operation flows down the game area 11. The game area 11 is provided with a start winning opening (hereinafter referred to as “start opening”) 12, a normal winning opening (hereinafter referred to as “normal opening”) 13, and a through chucker 14. When a game ball wins the start port 12 or the normal port 13, a predetermined number of game balls are paid out as a prize ball. The game balls that have been paid out can be used for games. The start port 12 is provided with a pair of movable pieces 12a. The start opening 12 changes the winning rate of the game ball by opening and closing the movable piece 12a. When the movable piece 12a is opened, a game ball can easily enter the start port 12. Whether or not to open the movable piece 12a is determined by an open lottery executed when a game ball passes through the through chucker 14. The result of the open lottery is displayed with a lamp 15a indicating a circle and a lamp 15b indicating a cross. When the game ball passes through the through chucker 14, either of the lamps 15a and 15b remains lit after the lamps 15a and 15b flash alternately. When the lamp 15a is turned on, it is “winning”, and when the lamp 15b is turned on, it is “lost”. In this way, the ◯ mark and the X mark function as “design” in the claims, and the alternating flashing of the lamps 15a and 15b functions as “variation display” in the claims. Although not shown in detail, the game area 11 is provided with game nails and windmills that change the movement of the flowing game balls.

  A center accessory 16 is provided at the center of the game area 11. A liquid crystal display 17 for displaying the result of the winning lottery is provided in the center accessory 16.

  The liquid crystal display 17 displays symbols 19 arranged in three columns, and each column 19 is composed of, for example, numbers 0 to 9 in one column. When a game ball wins at the start port 12, a winning lottery for determining a winning or losing is performed, and then the variation display of the symbol 19 is started, and the symbol 19 scrolls from top to bottom. The symbols 19 are sequentially stopped one by one (in the order of left column → right column → center). When all symbols 19 are stopped, the same symbol 19 is found, and the other combinations are lost. For this reason, when the same symbol 19 stops in the left and right columns, the reach state is reached. After the reach state is displayed, the same symbol 19 as the left and right symbols 19 stops at the center.

  If the winning is won, the normal mode is changed to the winning mode, the attacker 20 is released, and the round game is performed. When the attacker 20 is opened, the big prize opening is exposed from the board surface, and most of the game balls are guided to the big prize opening on the inner surface of the attacker 20. Thereby, a large number of prize balls can be obtained in the winning mode. The attacker 20 is closed when a predetermined number (for example, 10) of game balls wins in the big winning opening or when the opening time of the big winning opening becomes 30 seconds, for example, and the first round is ended. In the hit mode, the opening and closing of the attacker 20 is repeated and the process ends in the fifteenth round.

  The pachinko machine 10 can be played in the probability variation mode in addition to the normal mode and the winning mode. When transitioning to the probability variation mode, the probability of winning a win is higher than in the normal mode. Whether or not to shift to the probability variation mode is assigned with a probability of 1/2 when winning. When the transition to the probability variation mode is determined, the mode transitions to the probability variation mode following the hit mode. The probability variation mode ends when the opening time of the movable piece 12a reaches a certain time.

  A holding ball display unit 21 is provided above the liquid crystal display 17. The holding ball display unit 21 includes four lamps. When the pachinko ball wins the start opening 12 during the variable display of the symbol 19 or in the winning mode, the right of the winning lottery is carried over as a holding ball up to four. In the holding ball display unit 21, when one holding ball is stored, one lamp is turned on. The retained ball carried over is digested after the change display of the symbol or after the hit mode ends. When one reserved ball is consumed, one lamp of the reserved ball display unit 21 is turned off and the variation display of the symbol 19 is performed once.

  In FIG. 2, the pachinko machine 10 includes a control unit (opening control means) 30. The control unit 30 controls the overall operation of the pachinko machine 10 such as opening / closing control of the attacker 20 and display control on the liquid crystal display 17 in accordance with a game control program stored in the working memory 31.

  The start winning sensor 32 detects a game ball that has entered the start port 12. The normal winning sensor 33 detects a game ball that has entered the normal mouth 13. The through sensor 34 detects that a game ball has passed through the through chucker 14. The prize ball payout device 35 pays out a specified number of game balls as prize balls in response to a payout command input when a game ball wins at the start port 12 or the normal port 13. The game ball launching device 36 launches game balls one by one into the game area 11 in response to the turning operation of the launch handle of the player. The launch strength of the game ball is adjusted according to the amount of rotation of the launch handle. The attacker drive device 37 opens and closes the attacker 20 in the hit mode.

  The winning lottery unit 37 receives a command from the control unit 30 when a game ball wins at the start port 12 and performs a winning lottery using a random number to determine a winning or a lose. As the winning, a normal winning that is shifted only to the winning mode and a probability changing winning that is shifted to the probability variation mode after the winning mode are set. In the winning determination table used in the winning lottery, all random numbers extracted in the lottery are assigned with one of lost, normal winning, and probability variation. Then, the random value extracted at the time of the lottery is checked against the hit determination table to determine the loss, the normal win, or the probability change win. The winning determination table is composed of a normal table used in the normal mode and a probability variation table used in the probability variation mode. The normal table has a winning probability of 1/360, and the probability variation table has a winning probability of winning. It is set to 1/350. In any table, the number of random values is determined so that the normal hit and the probability variation are each selected as 1/2. Therefore, the winning probability per probability change is 1/720 in the normal mode, and the winning probability per probability change is 1/700 in the probability variation mode.

  Note that in the winning lottery, only the loss or the winning may be determined, and when the winning is won, the lottery for determining the normal winning or the probable change may be executed separately from the winning lottery.

  The open lottery unit 39 performs an open lottery using a random number in response to a command input from the control unit 30 when a game ball passes through the through chucker 14, and determines whether or not to release the movable piece 12a. . When the open lottery is performed, the control unit 30 blinks the lamps 15a and 15b alternately and lights the lamps 15a and 15b according to the lottery result. When the open lottery is won, the control unit 30 drives a solenoid (not shown) that drives the movable piece 12a to cause the movable piece 12a to perform an opening operation.

  The opening control pattern lottery unit 40 performs an opening control pattern selection lottery using a random number in response to a command input from the control unit 30 when winning per winning change in the winning lottery. Whether one of the opening control patterns opens the movable piece 12a during the probability variation mode is determined. The result of the opening control pattern selection lottery is written in the working memory 31 and is held until the probability variation mode ends. In the first opening control pattern, the blinking time of the lamps 15a and 15b is 10 seconds, the opening number of the movable piece 12a is one time per opening lottery, and the opening time is 6 seconds. In the pattern, the blinking time of the lamps 15a and 15b is 0.5 seconds, the number of times of opening the movable piece 12a is 3 times per winning of the opening lottery, and the opening time is 1.5 seconds. In the normal mode, the movable piece 12a is opened by the third opening control pattern. In the third opening control pattern, the blinking time of the lamps 15a and 15c is 8 seconds, and the number of opening of the movable piece 12a is one for each winning lottery, and the opening time is 0.2 seconds.

  The timer 41 is activated each time the movable piece 12a is opened in the probability variation mode. In the timer 41, the accumulated open time of the movable piece 12a after shifting to the probability variation mode is counted. The time of the timer 41 is cleared when the probability variation mode ends.

  Next, the flow of processing when the movable piece 12a is opened will be described with reference to FIG. When a game ball passes through the through chucker 14 and is detected by the through sensor 34, an open lottery is performed. When the open lottery is won, the movable piece 12a is opened with an open control pattern corresponding to the game mode.

  In the normal mode, the movable piece 12a is opened in the third opening control pattern, and after the lamps 15a and 15b blink for 8 seconds, the movable piece 12a is opened once with an opening time of 0.2 seconds.

  In the case of the probability variation mode and when the first opening control pattern is selected by the opening control pattern selection lottery, the movable piece 12a is released once with an opening time of 6 seconds after the lamps 15a and 15b blink for 10 seconds. To do. When the first opening control pattern is selected, the control unit 30 displays the blinking time of the lamps 15a and 15b from the liquid crystal display 17. When the first opening control pattern is selected in the probability variation mode, the blinking time of the lamps 15a and 15b and the opening time of the movable piece 12a are longer than the other patterns, so that the game ball is blinking while the lamps 15a and 15b are blinking. If the so-called stop-off is performed, in which the game ball is fired only when the movable piece 12a is released, the game ball can be efficiently increased. Thereby, the interest of the game in the probability variation mode can be enhanced, and the probability variation mode does not feel redundant in the game even for a long time. Since the flashing time of the lamps 15a and 15b is displayed from the liquid crystal display 17, it is possible to stop by using this as a guide.

  In the case of the probability variation mode and when the second opening control pattern is selected by the opening control pattern selection lottery, the movable piece 12a is opened for 1.5 seconds after the lamps 15a and 15b blink for 0.5 seconds. Open 3 times in time. Regardless of the type of opening control pattern, the control unit 30 ends the probability changing mode when the cumulative opening time of the movable piece 12a reaches a certain time in the probability changing mode.

  In the above embodiment, the opening control patterns of the movable piece 12a are three patterns, but the types of opening control patterns may be set as appropriate. Further, although the result of the open lottery is displayed by the lamps 15a and 15b, the result of the open lottery may be displayed by an appropriate method such as providing a 7-segment display or using the liquid crystal display 17.
