  • Patent number: 7070506
    Abstract: A pinball machine having an inclined playfield supporting a plurality of game features and a rolling game ball. A processor is used to control the function of the pinball machine including permitting game play in a tournament mode wherein game play allows a player to earn a score that is evaluated to determine if a prize is to be awarded. The processor may also allow for game play in a normal mode wherein game play does not provide for a prize to be awarded. When both game play modes are available, a player operated switch may be provided for permitting player selection of the mode of play at the beginning of each game.

  • 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.

  • Patent number: 5833236
    Abstract: A wrecking ball play feature for a pinball game includes a crane disposed upon the playfield of the pinball game. A wrecking ball is suspended from the crane by a cable so that it may be impacted by a game ball rolling upon the playfield. After being struck by the game ball, the wrecking ball swings in a pendulum-like fashion so as to strike targets near the crane, thus increasing the player's score. Alternatively, the wrecking ball may block a passage, the access of which by the game ball increases the player's score. The wrecking ball may be raised or lowered so that the pinball game features two or more modes of play. In one embodiment, the wrecking ball is raised and lowered by pivoting the crane arm about a pivot connection with the crane tower by way of a solenoid connected between the crane arm and the playfield. In another embodiment, the wrecking ball is raised by retracting the cable into the crane arm by way of tilting a crank to which the cable is connected.

  • Patent number: 5707059
    Abstract: A pinball game is provided with a control system which enables a game player to choose between a novice mode of play and a normal mode of play. In novice mode, game play proceeds for a predetermined time, regardless of the number of game balls played and selected game features, such as the tilt sensor, may be disabled. Game bonuses and free games may be made unavailable in novice mode to encourage experienced players to play in normal mode.

  • Patent number: 5186462
    Abstract: The play feature of the invention consists of a ball projecting mechanism mounted for rotary motion about an axis disposed substantially perpendicular to the playfield. When a ball enters the projecting mechanism, a motor is activated which rotates the projecting mechanism about the axis. The player, by pressing a button, can control when the projecting means is fired thereby to control the direction of travel of the ball. A series of play features can be located at a position on the playfield spaced from the projecting mechanism to provide targets for the player.
