  • Patent number: 5915693
    Abstract: A game ball cradle is positioned upon the playfield of a pinball game. A player-controlled solenoid plunger mechanism "pops" a ball positioned within the cradle into the air. A wire form jump rope is rotatably connected to an electric motor. The jump rope is positioned so that when it is rotated, it will pass under a game ball that has been properly "popped" by the player. A switch indicates to the game microprocessor that the jump rope has completed a revolution. Optical detectors indicate to the game microprocessor that the game ball is within the cradle so that the electric motor may be activated and, upon completion of a successful "jump", the player's score incremented and the speed of the jump rope rotation increased.

  • Patent number: 5913516
    Abstract: A play feature for a pinball game features a multimode target with a variable trajectory ball ramp. The multimode target features a pair of distinct targets mounted upon the playfield of the pinball game in a rotating fashion. The multimode target may be rotated between positions whereby each of the distinct targets is exclusively accessible by the game ball thus providing the pinball game with more than one mode of play. A variable trajectory ball ramp is positioned upon the playfield and is curved and banked towards the multimode target. A pinball properly negotiating the ramp may strike the multimode target so as to increase the player's score. The multimode target may oscillate and the distinct targets may feature a number of sub-targets as well as oscillating barriers.
