PROBLEM TO BE SOLVED: To provide a game machine of new interest in which the theoretical probability of a game ball which enters a variable ball entrance to intrude a specified area is increased on the basis of the drawing of a winning. SOLUTION: The judgment processing of a small winning 1 and a small winning 2 is performed when a game ball enters a start port, and a variable winning port is opened on the basis of the lapse of "1.0 sec" with the fact that the game ball enters the start port as a reference when the small winning 1 is determined. Since a rotor is started from an initial state disadvantageous to a player at the opening timing of the variable winning port when the small winning 1 is determined, it does not easily intrude into a big winning hole. When the small winning 2 is determined, the variable winning port is opened again on the basis of the lapse of "4.1 sec" with the fact that the game ball enters the start port as a reference. When the small winning 2 is determined, since the rotor stand still in a state advantageous to the player at the timing of re-opening the variable winning port, the game ball intrude into the big winning hole at a very high probability when it enters the variable winning port.
