Abstract
A slot machine has a micro-computer comprising a table memory for storing information as to symbol arrangements on reels rotatably arranged side by side, and a memory for storing information as to the numbers of coins or tokens to be paid out according to predetermined prize-winning combinations of symbols. Upon the reels being stopped, individually, the table memory is accessed with address signals corresponding to the stopped positions of the respective reels which are detected by counters associated therewith as to prize-winning combinations of symbols that have occurred in the prize-awarding rows in such a way that all of the symbols read out from the table memory are compared with a respective one of the predetermined symbols read out one after another.
