PROBLEM TO BE SOLVED: To enable a diversified setting of chances for notifying of the probability state leading to the remedy of players in a game machine which enables the alteration of the lottery probability for determining whether the shift should be made to a special game advantageous for players to the low-probability state from the high-probability state. SOLUTION: The game machine is provided with a probability alteration lottery means which carries out an alteration lottery to determine whether or not the alteration should be made to the low-probability state when a variable display game containing an attached game is executed in the high-probability state after the end the special game advantageous for the players, a differential number of ball computation means which computes the differential number of balls between the game balls used shot to a playing area and the total of prize balls put out equivalent to those winning the prize winning slot and a notification execution decision means which determines whether the notification should be made of the alteration to the low-probability state from the high-probability state according the frequency of the variable display game executed until the shift to the special game and the result of the computation by the differential number of ball computation means during the execution of the attached game.
