A gaming machine that adjusts a base value (winning rate) in a high-probability gaming state by a novel method and does not cause variation in the base value (winning rate). For example, a special symbol is displayed in a first display area of a variable display device, and a normal symbol is displayed in a second display area of the variable display device. When the big hit symbol is displayed in the first display area, the gaming machine changes the variable winning opening to a state advantageous to the player. A variable starting winning opening control means for changing the variable starting winning opening to a state advantageous to the player when the normal symbol becomes a winning symbol, and a probability of obtaining a big hit when the probability changing symbol is displayed in the first display area. And a probability varying means for outputting a probability varying signal; a base managing means for managing a base value one by one when the probability is varied, and outputting a base value; and a variable according to the probability varying signal and the base value. Base value changing means for changing a base value by changing a winning probability to the starting winning opening. [Selection] Fig. 28 |
