Abstract: To provide a game machine capable of suitably enhancing interest in a game.SOLUTION: While a low-probability jackpot result can be obtained when a jackpot result is obtained after winning/losing determination for hold information at a side of a first special symbol, a high-probability jackpot result is obtained when a jackpot result is obtained after winning/losing determination for hold information at a side of a second special symbol. In this case, a winning/losing lottery mode becomes a high-probability mode in a first high-probability state, the hold information at the side of the second special symbol becomes a priority target, a jackpot result is obtained with the hold information at the side of the first special symbol as an opportunity before a jackpot result is obtained with the hold information at the side of the second special symbol as an opportunity and an opening/closing execution mode results, thus preventing a phenomenon resulting in the opening/closing execution mode from occurring easily. The hold information at a side of the priority target is switched according to a game state. A pattern display device 51 executes a performance for a game round corresponding to a game round at the side of the priority target.SELECTED DRAWING: Figure 11
