Abstract: A gaming machine is provided with a principal variable display for displaying principal graphical information corresponding to at least one of a plurality of principal graphical elements, each such principal graphical element having a predetermined significance in a principal game of the gaming machine. A secondary display displays secondary graphical information that constitutes any combination of secondary information predictive of the results that will be obtained in the play of the principal game, a secondary game, and/or timing information. A principal controller produces first control signals that control the principal variable display to display the principal graphical information as a sequential principal progression of the principal graphical elements, and second control signals that control the secondary display to display the secondary graphical information. The secondary graphical information has a predetermined relationship to the sequential progression of the principal graphical elements.

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”).

Abstract: In a game machine, game result conditions may be randomly selected for a predetermined number of games among a plurality of given game result conditions and a demonstration may be made to provide a player of the game with a feeling of higher probability of winning a prize in the game when the randomly selected game result conditions include a given specific game result condition. The demonstration may be made by a variety of possible techniques, including using a flashing light or changing the volume or tone of a sound. Random numbers may be sampled in advance for random selection of game result conditions for the current game and for one or more games that will follow the current game, i.e., ranging several games down from the current game. These random numbers may be used to determine whether or not a demonstration should be made in the current game.
