Abstract

When a predetermined amount of credits has been inserted into a slot machine, the game mode is switched from a non-insurance mode to an insurance mode according to the player's input operation via a touch panel. In the insurance mode, the number of games is counted. When the counted game number has reached a predetermined number, a predetermined amount of credits is paid out. In a case where the amount of credits paid out according to the rearranged symbols is equal to or greater than a predetermined amount, the counted number of games is reset. On the other hand, the predetermined amount is changed based on the change in the maximum bet amount according to the input operation via a setting change switch, which allows the set value of the maximum bet amount to be changed.
