PROBLEM TO BE SOLVED: To provide a pinball game machine capable of achieving game characteristics of suddenly switching a game state into a probability variable state without previous notice. SOLUTION: A first lottery is carried out triggered by the entry of a game ball into a starting port, and the result of the lottery is displayed on a rendering display device. When winning a prize, a big prize hole is opened to perform a jackpot game. A second lottery is carried out triggered by detecting the shooting of a game ball, but the result of the lottery is not displayed on the rendering display device. In the second lottery, the big prize hole is opened in a form of making the entry of the game ball more difficult than the case of winning the prize in the first lottery, and then a lottery on whether to perform a special jackpot game for starting a probability variable state is carried out. In this manner, the player's attention is attracted to the first lottery, and the presence of the second lottery can be hidden from the player. Game characteristics of suddenly switching into the probability variable state without previous notice can thereby be achieved by starting the probability variable state after the termination of the special jackpot game by winning the second lottery.
