Slot machine with wild symbol feature and control method thereof

Abstract

In a slot machine, symbols are scrolled in plural display areas provided on a display at an execution of a slot game and then stopped in the display areas respectively. Furthermore, if a “JOKER” symbol has come to a stop in a central display area, a “WILD” symbol(s) displayed in the remaining display areas is activated. If a “JOKER” symbol has not come to a stop in the central display area, a “WILD” symbol(s) displayed in the remaining display areas is deactivated. Therefore, since dividends may vary largely according to a symbol displayed in the central display area, a slot machine producing a superior entertainment feature with a “WILD” symbol can be provided.
