PROBLEM TO BE SOLVED: To provide a game machine, surely consuming the frequency of continuation of time-shortening to relieve a game player stuck in a game. SOLUTION: In this Pachinko game machine 10, the period (the frequency of time-shortening) of a first high probability lottery mode (the time-shortening state) set at the end of a big prize is set to be different depending on the game state before the big prize, and the highest frequency of time-shortening is given in the case of transition from the low probability state to the high probability state. In the case of transition from the high probability state to the low probability state, when the residual frequency of time-shortening before transition is larger than the predetermined frequency, the residual frequency of time-shortening is set as the frequency of time-shortening.
