Abstract (en)

A slot machine having a plurality of symbol rows each having a plurality of symbols disposed at equal pitch pays out a predetermined number of coins when the symbol rows under movement stop and a symbol combination on a prize-winning line becomes coincident with a hit game symbol combination. The slot machine includes a lost game determining unit (20, 42, 43), a symbol determining unit (43, 44, 45) and a symbol row stop position control unit (28, 29, 30). The lost game determining unit (20, 42, 43) determines if a present game is to be set as a lost game or a hit game. The symbol determining unit (43, 44, 45) responds to a present lost game and determines symbols of the respective symbol rows so as to obtain a highest probability of occurrence of a symbol combination nearest to a hit game symbol combination. The symbol row stop position control unit (28, 29, 30) controls the respective symbol rows such that the symbols determined by the symbol determining unit (43, 44, 45) stop on the prize-winning line.
