SOLUTION: When one is entitled to a plum and does not operate stop buttons 19a to 19c following a prescribed operation procedure, a control section 30a controls first to third reels 14a to 14c so as to prevent a plum pattern from stopping on an effective winning line and operates an AT (assist time) mode transition lottery section 41. The AT mode transition lottery section 41 determines whether to transit to the AT mode by lot. When a transition to the AT mode is determined, the control section 30a reads the execution program of a game from the ROM area of a memory 31. COPYRIGHT: (C)2004,JPO
