Abstract
Before the start of a free game, a slot machine displays a selection screen on a variable display portion and accepts a selection made by the player with respect to the first choice image and the second choice image. The first special reel band or the second special reel band including a larger number of condor symbols than the normal reel band is associated by lottery to the first choice image and the second choice image. The main CPU changes the normal reel band associated to each reel display portion to a special reel band based on the selection made by the player. Then, the main CPU executes a free game using the special reel band that was changed.
