PROBLEM TO BE SOLVED: To provide a game machine which can improve the attractiveness of games while securing the stability in the management of game parlors by preventing loss in the feeling of achievement over the games. SOLUTION: The game machine has the main CPU 201 which can carry out the control of a first jackpot game state in which a first major prize winning slot is operated to open or close in a first open/close mode that makes game balls easier to win, a second jackpot game state in which the major prize winning slot is operated to open or close in a second open/close mode that makes the game balls harder to win while being associated with the control of a high-probability state so as to facilitate the control of the jackpot game state and the dummy jackpot game state adapted to open or close the second major prize winning slot. When the control of the dummy jackpot game state is carried out, the main CPU 201 controls the operation of opening or closing the second major prize winning slot in the third open/close mode almost the same as the second open/close mode in which the second jackpot game state is carried out.
