Abstract

In conventional types of slot machines, the prize status is determined by random selection using random numbers for each game. In this type of conventional slot machine, for example, the current game prize status is determined by the random selection of the prize status when a token is put into the slot machine to operate the start lever. When the current game prize status is determined, the reels are rotated to begin the game. In the type of slot machine in which the prize status is determined by random selection using random numbers in the present invention, a demonstration is made by unusual lights or sounds or by unusual operations when the randomly selected prize status is a “big jackpot” or when a “big jackpot” is missed by one reel symbol among all the reels (this condition of two matching symbols is referred to as “one-shy”). In one method for making this demonstration, reel lights are provided on the reverse side of reel belts on which are imprinted the symbols around the reels, and these reel lights, which in conventional slot machines are flashed only when the prize status has been confirmed after all the reels have stopped, are flashed before all the reels stop. In the present invention, a demonstration is made by flashing reel lights when the game prize status is “one-shy,” making it possible to provide an exciting game environment which is visually appealing to the player and arouses the anticipation of the player.
