PROBLEM TO BE SOLVED: To improve an operation rate by giving a new decision material when selecting a game machine to a player and suppressing the decline of a desire to continue a game. SOLUTION: The drawing of regular symbols is performed when a game ball enters a winning gate, and a second start port is opened for the prescribed time when a winning is drawn by the drawing of the regular symbols. Further, when a game ball enters the second start port, the drawing of special symbols is performed. When a big winning is won by the drawing of the special symbols, a round game of opening a big winning port is executed, and a large amount of prize balls can be acquired. The opening time of the second start port is set to 1 second in the initial state of the game machine, and the opening time is shortened to 0.5 second when a small winning is won.
