PROBLEM TO BE SOLVED: To improve the interest of a game by heightening players' expectation of whether or not the game is controlled in a high-probability condition by carrying out a variety of performances. SOLUTION: The probability variation latency rate is 30% or 70% depending on an announcement of a shift of the performance mode to either an A mode or a B mode which is made in the variation of subsequent decorative patterns after a variable winning action is taken in accordance with an opening control pattern corresponding to the opening pattern of an opening KP1-2. Consequently, the game machine permits performance patterns to be increased and players to play a game in the expectation that the game is controlled in the probability variation condition by making it difficult to determine whether or not the game is controlled in a probability variation condition, whereby the interest of the game can be improved.
