PROBLEM TO BE SOLVED: To prevent changes in allowance levels for setting a probability with which allowance of the derivation of a winning display result is determined in each game from being immediately perceived by a player.SOLUTION: A winning probability of each winning combination in an internal lottery is determined according to difference of setting values. In a RAM, setting value work for storing data showing setting values is provided separately from work for storing data showing progress conditions of a game (credit, game state and the like) other than the setting values. When the power is turned ON with a setting key switch provided inside the slot machine being in an ON-state, setting change processing is performed, and the setting values stored in the setting value work in the RAM can be re-written. The data stored in the work other than the setting value work of the RAM is not cleared simply by turning ON the power with the setting key switch being in an ON-state, but it is cleared on condition that the power is turned ON with a data clear switch being in an ON-state in addition to the setting key switch. |
