<p>PROBLEM TO BE SOLVED: To provide a game machine that can properly execute jackpot pre-determination when performing the jackpot pre-determination and fall lottery.SOLUTION: A game machine is configured by: acquiring a jackpot lottery random number and a fall lottery random number by the game ball entry to a starting hole; performing a jackpot lottery using the jackpot lottery random number; executing a jackpot game when results of the jackpot lottery are affirmative; transferring the winning probability of the jackpot lottery from a low probability state to a high probability state after the jackpot game; executing a fall lottery using a fall lottery random number when the winning probability of the jackpot lottery is in the high probability state; and transferring the winning probability of the jackpot lottery from the high probability to the low probability in the case of affirmative results. The game machine executes fall pre-determination using the fall lottery random number when the winning probability of the jackpot lottery is in the high probability state. When the results of the fall pre-determination are affirmative, the jackpot pre-determination is performed in the low probability state. When the results of the fall pre-determination are negative, the jackpot pre-determination is performed in the high probability state.</p> |
