PROBLEM TO BE SOLVED: To provide a game machine which can further enhance the amusement of a game.SOLUTION: A game control part acquires a random number value regarding a special pattern, when a first start port switch or a second start port switch detects the passage of a game ball. The game control part determines on the basis of the acquired random number value whether or not to perform a special game (jackpot game etc.) advantageous of a player. If it is determined in the determination to perform the special game, the operation pattern of a big winning port and a round number are set, and a high probability state, a middle probability state, or a low probability state as a game state after the end of the jackpot game is set. The probability of the middle probability state being set as the game state is higher in the detection at the first start port switch than at the second start port switch. After the determination is done in a predetermined number of times in the high probability state or the middle probability state, the game state is moved to the low probability state. |
