PROBLEM TO BE SOLVED: To provide a game machine capable of opening/closing a big winning port provided on a game board at high speed. SOLUTION: Obstructing parts 94b obstructing take-in of a game ball from a lower side of big winning port holes 94a are aligned and erected along the lower side of the big winning port holes 94a. In a rotating member 91 rotatably supported to a big winning port device 9, locations corresponding to the obstructing parts 94b at the time of rotations around a rotation center shaft are notched, and opening parts 91a being allowed to pass through the obstructing parts 94b are formed. The rotating member 91 is connected to an operation member, and a big winning port 94 is opened after the opening parts 91a on the lower side of the rotating member 91 pass through the obstructing parts 94b when the lower side of the rotating part 91 rotates in one direction from the lower side to an upper side of the big winning port holes 94a on a front face side of the game board. In the operation member allowing the rotating member 91 to turn, a driving gear connected to a rotary shaft of a driving motor, an intermediate gear engaged with the driving gear, and a driven gear connected to a shaft part of the rotating member 91 so as to be engaged with the intermediate gear are used.
