In summary, the present invention is directed to a movable member facing a concave chamber formed in a mounting board attached to the surface of a game board.
The movable member is provided with a variable winning device that can be converted into a first state in which the game develops disadvantageously to the player and a second state in which the game develops in favor of the player by moving the movable member. A special prize port facing a continuation switch for continuing the second state and a general prize port for a normal prize; a prize probability changing device for changing a prize probability of the special prize port; Is switched between a state advantageous to the player and a state disadvantageous to the player based on the output of the specific right detecting means arranged in the game section,
Based on the output of the specific right means, the state of the winning probability varying device alternates between a state advantageous to the player and a disadvantageous state, and the winning probability of the special winning opening varies depending on the state of the winning probability varying device. Therefore, the continuation of the special game is facilitated, the number of prize balls to be acquired is increased, or the continuation of the special game is easy but the prize ball acquisition is not so expected, or the game may be varied. Since this change is difficult to predict, it is possible to provide an interesting pachinko machine that the player does not get tired of.
