A ball launch passage 92 that guides is defined. And the spring part 54a of the inner rail 54 functions as a backflow suppression means that suppresses the backflow of the game ball from the game area 52 to the ball launch passage 92.

  Further, the special winning opening 28, the ordinary electric accessory 26, the two operation openings 22, and the four general winning openings 24 are respectively arranged on the translucent plate 51 and below the game area 52. In the present embodiment, these are all arranged in a range of about a quarter of the lower side of the game area 52 so as not to obstruct the display screen 64a visually recognized through the translucent plate 51 as much as possible. The out port 58 is provided at the lowermost part of the game area 52. Among the game balls launched into the game area 52, game balls that have not entered any of the ordinary electric accessory 26, the big prize opening 28, and the general prize opening 24 are played through the out area 58. Discharged from.

  The big winning opening 28 is arranged at the approximate center in the width direction of the game area 52 and above the out opening 58. The big prize opening 28 includes a ball entry detecting device 38 for detecting the entry of a game ball and a big prize opening solenoid 62 for opening and closing the opening and closing member, and the reception state of the game ball is disadvantageous for the player. It is configured as a variable pitching device that changes between a state and an advantageous state. That is, the opening / closing member of the special winning opening 28 can be opened / closed by controlling the driving of the special winning opening solenoid 62. The game ball cannot enter the closed prize opening 28 in the closed state, and can enter the big prize opening 28 only when it is opened.

  The ordinary electric accessory 26 includes an incoming ball detection device 36 for detecting the entrance of a game ball and an ordinary electric actor solenoid 60 for opening and closing the opening / closing member. The ordinary electric accessory 26 is disposed approximately at the center in the width direction of the game area 52 and above the special winning opening 28. Entering a game ball into the ordinary electric accessory 26 triggers a lottery to open the grand prize opening 28.

The two right general winning openings 24 are formed integrally with the right cover 43. Further, the two left general winning award ports 24 are formed integrally with the left cover 44. The game balls that have entered the general winning opening 24 are guided to a ball discharge path provided on the back side of the translucent plate 51. The general winning opening 24, the right cover 43, and the left cover 44 are formed of a light-shielding material. Thereby, the player cannot visually recognize the ball discharge path provided on the back side of the translucent plate 51.

  In the present embodiment, a liquid crystal display device (LCD) having a large display screen 64a is employed as the display device 64 disposed on the back side of the light transmitting plate 51. The display screen 64 a has the same width as the game area 52 and has a slightly smaller height than the game area 52. As described above, in the pachinko gaming machine 10, the visual effect during the game can be easily improved by arranging the display device 64 having the large display screen 64a behind the game board 50. As the display device 64, another device having a flat display screen such as an organic EL display or a plasma display may be employed.

  A special symbol display area 86 for variably displaying special symbols is provided on the right side of the display screen 64a. The special symbol is a symbol corresponding to the result of a lottery performed when a game ball enters the ordinary electric accessory 26, and has a role of indicating whether or not to generate a jackpot. In the special symbol display area 86, for example, numbers “0” to “9” are displayed as special symbols. Further, in the vicinity of the special symbol display area 86, a reserved ball display area 88 is provided for displaying the number of reserved balls of the fluctuation of the special symbol. The number of reserved balls indicates the number of winning balls that have not been changed yet.

  In addition, a decorative symbol display area 90 is provided substantially at the center of the display screen 64a. In the decorative symbol display area 90, an effect image including a decorative symbol linked to the special symbol is displayed in a variable manner. The decorative symbol is a symbol for visually producing the result of the special symbol lottery indicated by the special symbol. In the decorative symbol display area 90, as a decorative symbol, for example, a plurality of rows of symbols imitating a slot machine game are displayed in a variable manner.

  A normal symbol display device 82 including an LED is provided on the left side of the game area 52. Further, in the vicinity of the normal symbol display device 82, a holding ball lamp 84 for changing the normal symbol is provided. The normal symbol variation holding ball lamp 84 is composed of three lamps, and displays the number of reserved balls of the normal symbol variation depending on the number of lights. The number of held balls indicates the number of balls that have not been executed yet.

  In the pachinko gaming machine 10 configured as described above, when the player rotates the launch handle 17, the game balls stored in the upper ball tray 15 are launched one by one with the strength corresponding to the rotation angle. It passes through the launch passage 92 and enters the game area 52. When the player fixes the position of the launch handle 17, the launch of the game ball is repeated at regular time intervals. A game ball that has entered the upper part of the game area 52 falls in a direction according to how it hits while hitting a plurality of game nails and windmills. When a game ball enters any of the general winning port 24, the operating port 22, the ordinary electric accessory 26, and the big winning port 28, the winning ball corresponding to the type of the winning port is the upper ball tray 15 or the lower ball. It is paid out to the dish 16. The game balls that have entered the winning ports such as the general winning port 24 are processed as safe balls, and the game balls that have entered the out port 58 are processed as out balls. In the present specification, “incoming”, “entered ball”, and “winning” include “pass”, respectively.

  When a game ball enters the ordinary electric accessory 26, the special symbol is displayed in a variable manner in the special symbol display area 86. At this time, in the decorative symbol display area 90, the decorative symbol is variably displayed in a manner interlocked with the variable symbol display. The variable display of the special symbol display area 86 and the decorative symbol display area 90 is stopped after elapse of a display time determined in advance. If the special symbol and the decorative symbol at the time of the stop are the winning mode, the gaming state shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the special winning opening 28 is started. At this time, the decorative symbols simulating a slot machine game show a state in which the three symbols match. The grand prize winning opening 28 is temporarily closed after being opened for about 30 seconds or after nine or more game balls have entered. Such opening and closing of the special winning opening 28 is repeated, for example, 15 times under a predetermined condition.

  If a special condition is further met when a special game occurs, a probability variation game (hereinafter referred to as “probability variation”) or a time-variation variation game (hereinafter referred to as “time reduction”) is specified as a specific game after the special game is completed. Be started. During probability change, a lottery with a higher win probability than usual is performed, and a new special game is generated relatively early. The time reduction is continued until, for example, the special symbol fluctuates 100 times. During the time reduction, the variation time of the special symbol is shortened.

  When the game ball passes through the operation port 22, the normal symbol is variably displayed on the normal symbol display device 82 for a predetermined time. When the normal symbol stops in a predetermined hit state after the lapse of a predetermined time, the normal electric accessory 26 is opened for a predetermined time. Normally, the probability that a normal symbol stops in a hit state is set to be relatively low, but the probability is increased during the time reduction, and thus the probability that the ordinary electric accessory 26 is released during the time reduction is also increased. . Further, during the time reduction, the normal symbol fluctuation display time is shortened, and the time during which the ordinary electric accessory 26 is in the open state is set relatively long. As described above, during the time saving, the ordinary electric accessory 26 is easily opened, and the number of times and the opening time are increased. Therefore, the ease of accepting a game ball in the ordinary electric accessory 26 greatly varies depending on whether the time is short or not, and a large difference occurs in the number of balls that are awarded to the ordinary electric accessory 26. That is, during the time saving, the player can advance the game with almost no reduction in the number of balls, so that a large profit can be given to the player during that time.
