ABSTRACT:
A slot machine has a game number counter which cumulatively counts the number of games played. Whether the number of games counted by the game number counter reaches a predetermined number or not is detected by a comparator; and if both numbers coincide, a coincidence signal is output from the comparator. The slot machine has also a winning number counter which cumulatively counts the number of wins occurring during the period until the number of games reaches the predetermined number. At the time the coincidence signal is obtained, the number of wins cumulatively counted by the winning number counter is compared with a standard number of winnings. As a result of this comparison, if the number of wins in the winning number counter is larger than the standard number of wins, the following game is set to decrease the likelihood of a win; but in the contrary case, the same control is actuated for shifting a winning combination of symbols onto a winning line.
