PROBLEM TO BE SOLVED: To provide a slot machine which can heighten a player's interest with a shift to a special game condition and can ensure the fairness of a game. SOLUTION: A CPU 41a operates a regular bonus, at the same time as a shift to a big bonus and judges whether or not the regular bonus is operating for one game during the big bonus. When it is judged that the regular bonus is not operated yet, the CPU operates the regular bonus again, thereby usually controlling to the regular bonus while the big bonus is operating. The CPU 41a judges whether or not a set value is appropriate every time when an internal lottery is held. If the set value is not appropriate, the CPU disables the progress of a game until a new set value is set by the change of the set value. COPYRIGHT: (C)2007,JPO&INPIT
