PROBLEM TO BE SOLVED: To solve a problem of varying the expectation of a player by varying the probability of the operation of a first game state according to the state of satisfaction of a prescribed condition because an internal winning role related to the combination of first symbols may be or may not be determined according to whether it is within a prescribed period of time or not after the termination of operation of a second game state or not if the range of numeric values to which a random number value extracted based on the starting operation belongs is a specific one. SOLUTION: When the number in a replay time (RT) game number counter is "0" when the winning number determined based on the extracted random number value and an internal lottery table is "5", a regular bonus (RB) is determined as an internal winning role by referring to a first internal winning role determining table. When the number in the RT game number counter is not "0", a big bonus (BB) more advantageous to the player than the RB is determined by referring to a second internal winning role determining table. When the operation of the BB is terminated, the number "100" is stored in the RT game number counter. COPYRIGHT: (C)2007,JPO&INPIT
