摘要 A processer randomly designates the predetermined number of special symbol display areas from among symbol display areas when a free game starts. Subsequently, reels stop rotating to position a symbol in each of the symbol display areas. In case wild symbol(s) is/are repositioned in the specific symbol display area(s), the wild symbol(s) repositioned in the specific display area(s) will be placed and maintained in a hold state in subsequent free game(s). In the subsequent free game(s), symbols will be repositioned in symbol display areas other than one(s) in which the wild symbol(s) has/have been placed in a hold state.
