  • Patent number: 6110043
    Abstract: A method of operating of controller-based progressive gaming system having a plurality of gaming machines wherein each gaming machine generates unit bet information indicative of a number of unit bets supplied to a machine for playing a game. The method comprises the steps of randomly selecting a bonus mode activation value between a high and low limit, providing a current value, providing a base value, incrementing the current value when the gaming machines are played so that the current value is incremented by a fixed amount of each unit bet received by each gaming machine. A bonus mode time period is entered when the incremented current value is equal to or exceeds the bonus value. Eligible machines are locked-in and random bonus jackpots are made during the bonus time period. Each bonus award decrements the current value by the amount of each award and the bonus mode time period is ended when the current value is less than or equal to the base value.

  • Patent number: 6059289
    Abstract: A method is set forth for playing a bonus game in a secondary slot machine adjacent a primary slot machine. The primary slot machine issues a bonus qualifying signal to the secondary slot machine to start play of a bonus game when a bonus qualifying event occurs. The reels of the bonus game include value symbols, null symbols, and end game symbols which may be of two basic types: a lose game symbol and a stop game symbol. After the random spin, the values of any value symbols displayed on the payline of the secondary slot machine are accumulated into an accumulated winning value. The value symbols could include positive integer values, negative integer values, and multiples. The random spinning, determination of values of any value symbol and the accumulation of a winning value is repeatedly continued until an end of the bonus game occurs.

  • Patent number: 6047963
    Abstract: A Pachinko bonus game system for an underlying game machine. The Pachinko bonus game has a playing field with a plurality of rows of pegs. A ball is launched onto the playing field by a launch mechanism when an initiate condition occurs during play of the underlying game. A row of lanes are provided on the playing field. The ball, after traversing among the pegs on the playing field, eventually travels through one of the lanes. At each lane is randomly displayed a bonus payoff value. The lane the ball travels through senses the presence of the ball and the value displayed for that lane is added to the credit meter in the underlying game. The bonus payoff values are randomly changed from game to game which eliminates any mechanical bias present in the Pachinko game. A stand-alone Pachinko game as well as using a Pachinko game as a coin dispenser is also provided.

  • Patent number: 5947592
    Abstract: A visual display sign having a lighting unit. The reflector in the lighting unit is nearly completely sealed and has a reflecting surface that spreads the emitted light about eight degrees from the plane of circumference of the reflector. To cool the lighting unit, air is directed along the rear surface of the sealed reflector. A small amount of the air enters the sealed reflector, causing a buildup of pressure inside the reflector and preventing any additional air from entering the reflector. This cooling system minimizes dust buildup on the reflective and light-emitting surfaces inside the reflector. The lighting units are attached to the visual display sign at a downward angle of about eight degrees from the horizontal.
