PROBLEM TO BE SOLVED: To provide a game machine for executing a new performance mode to replace the performance mode at a previous stage during a performance period of the previous stage in a ready-to-win performance capable of developing from the previous stage to a next stage without letting the performance mode become monotonous, while lowering of excitement and enjoyment in the game can be suppressed. SOLUTION: When a special background 51b is displayed and controlled, the special background performance is executed during the performance period in which a normal ready-to-win performance supposed to be executed in a normal background 51a, and right and left decorative symbols 50a, 50c are stopped and displayed after executing the special background performance, thereby preventing a player from being irritated by the normal ready-to-win performance and bored with the normal ready-to-win performance which does not provide expectation for a jackpot.
