SOLUTION: The frequency of vertical movement of an engaging board 118a equipped in front of a stage 118 made random timing in an ordinary activation time and a game ball guided onto the stage 118 is repeatedly retained and retain-released. When a small prize winning is achieved and an electric tulip of a special pattern starting port 116 is opened in an ordinary pattern game, a lot of prize winning can be expected when the opening timing and the timing of vertical movement of the engaging board 118a are coincided well. When a jackpot prizing is completed in a variable probability pattern, the game gets into a special condition in which the vertical movement of the engaging board 118a is synchronized with the small prize winning timing to enable more game balls can get into a prize winning port. |
