PROBLEM TO BE SOLVED: To provide a game machine which prevents a game from becoming monotonous. SOLUTION: According to the game machine, a player plays a game by betting three tokens in a regular mode. When the player wins an SB winning probability in a winning combination lottery and then wins an SB, the game machine is shifted from the regular mode to an SB mode. In the SB mode, the player plays a game by betting the two tokens. When the player wins a replay winning probability in the SB mode, he or she can play the subsequent game in the regular mode by betting the two tokens. In the game performed by betting the two tokens in the regular mode, the winning probability of a BB is higher than that in a game by betting the three tokens. COPYRIGHT: (C)2009,JPO&INPIT
