PROBLEM TO BE SOLVED: To provide a game development for increasing frequency of frequent occurrence of winning by a predetermined symbol combination, and variously changing establishment frequency of winning. SOLUTION: A control mode in which winning flags related to a specific role are easily accumulated and a control mode in which pull off control of the winning symbol using the accumulated winning flags is performed. A control unit performs a game by the accumulation mode until the number of accumulated winning flags becomes a predetermined value, and moves to the discharge mode in response to the accumulation of the winning flags of the number exceeding the predetermined value. When the number of accumulations is decreased to the predetermined number by the discharge mode, the game returns to the accumulation mode. The accumulation process of the winning flags comprises a kicking process of a winning symbol, a process of making the number of sliding pieces in the pull off control of the winning symbol smaller than a usual, or a process of increasing frequency of internal winning to replay.
