Abstract

A scatter object symbol is randomly selected among plural symbols. The symbols are rearranged. A payout determined by a combination of the symbols rearranged on a payline is awarded.

It is notified contents of a payout determined on the basis of the scatter symbol and the corresponding payout is awarded.
