PROBLEM TO BE SOLVED: To provide a game machine which gives an interest to a player in selecting the game machine, in game machines which can generate a probability ambiguous mode. SOLUTION: In the game machine capable of generating the probability ambiguous mode (expectation mode) wherein vague information is given as to whether the state of probability of a big win in a special pattern variable display game is the state of high probability or that of low probability, a probability ambiguous mode display control means (performance control device 300) enables display of the probability ambiguous mode when the result of display of the special pattern variable display game is that of generation of a probability ambiguous state wherein the display of the probability ambiguous mode is performed and when a period determining means (performance control device 300) determines that a game ball has not entered, as a winning ball, into a general prize-winning opening 35, a normal pattern starting gate 34, a first starting prize-winning opening 36, a normal variable prize-winning device 37, etc. for a prescribed period.
