Abstract

When three or more feature symbols are stopped on the variable display portion, the slot machine provides a free game. In the bonus game process, the main CPU determines the number of game condition choice images to be displayed on the selection screen according to the number of feature symbols that have been stopped on the variable display portion. When one of the game condition choice images is selected from the game condition choice images displayed on the selection screen by the player, the main CPU executes the free game according to the free game execution condition associated with the selected game condition choice image.
