Abstract

See full text

A slot machine having a plurality of symbol series disposed side by side and movable lengthwise independently, selects a combination of symbols on a winning line which is judged as to whether it coincides with any one of the predetermined prize-winning symbol combinations to pay out a predetermined number of coins. At least one of the symbol series includes a special mark as distinguished from the symbols. When the slot machine selects any one of the predetermined prize-winning symbol combinations, and one of the symbols of this combination is replaced with the special mark, the slot machine pays out coins as a special dividend the number of which is larger than that of coins to be paid out upon the one predetermined prize-winning symbol combination.
