PROBLEM TO BE SOLVED: To provide a game machine which is equipped with game properties always giving a feeling of tension that does not bore a player by making a mode (a game state) movable until a next jackpot occurs after a game transits to a jackpot game and with a mode after the jackpot game which can keep the player motivated for playing.SOLUTION: There is provided an opening extension function of ordinary electric accessories after a jackpot game which performs win/lose lottery determination caused by ball entry to a first start port where ball entry is normally possible and a second start port composed of ordinary electric accessories at prescribed win/lose lottery probability by giving priority to the second start port and executes a jackpot game when a result of the win/lose determination is jackpot. As different states of the win/lose lottery probability, there are provided a normal state, a middle probability state, and a high probability state. Probability transition means more easily performs distribution to the high probability state in the middle probability state than in the normal state, performs fall lottery determination, more easily performs transition to an opening extension state in the high probability state during a non-opening extension state, and performs opening extension determination at prescribed transition lottery probability, regardless of the win/lose probability lottery probability in the opening extension state.SELECTED DRAWING: Figure 8 |
