ABSTRACT:
In a slot machine, a token is inserted to play a game. The slot machine pays tokens when the game results in a win, which comprises a normal win, or a big win for which more tokens are paid than for the normal win. The game comprises a normal game, or a bonus game whose winning probability is higher than the normal game. The bonus game is triggered when a big win is acquired. The slot machine generates a play signal representing a play of the game and a big win signal representing a big win. A display apparatus is associated with the slot machine, and has 16 DIP switches which are set with reference to the slot machine, and signal information regarding the slot machine. In the display apparatus, a normal game counter counts the times of having played the normal game between the completion of playing the bonus game and the occurrence of a big win, whereas a big win counter counts the number of times of a big win. A microcomputer receives the information from DIP switches, and causes 4-digit and 2-digit LEDs responsively to display the count values of the two counters. In a microcomputer, a subtracter calculates a net reward number of tokens rewarded by the slot machine. While playing the bonus game, the LEDs display the net reward number. The same display apparatus is adaptable to a pinball machine in which a ball is bet to play a game, and operates similarly.
