  • Patent number: 5417423
    Abstract: The play feature for a game of the present invention comprises a multiple kicker ramp including a plurality of spaced-apart longitudinal dividers which define parallel ball lanes and a plurality of perpendicular paths between the ball lanes. Balls enter the ramp from the playfield. A ball sensor is provided in each of the perpendicular paths, each sensor associated with a different point value. A multiple kicker element, which is activated by a player controlled switch, is provided in one of the ball lanes to direct a ball to the other ball lane over one of the perpendicular paths to activate its ball sensor. This causes the point value of the activated sensor to be added to the player's score.

  • Patent number: 5356141
    Abstract: The play feature for a pinball game of the present invention comprises a roulette scoring device mounted above the playfield which includes a horizontally rotating wheel having a plurality of apertures arrayed around its periphery. A different point value indicated to the player is associated with each of the apertures. Pinballs can enter the roulette scoring device not only from the shooter lane, but also from a ramp disposed on the playfield. An optical switch or microswitch included in the ramp adjacent a holding device and a microswitch in the shooter lane generate signals sent to the game microprocessor to cause the wheel to rotate. An optical switch mounted on the playfield senses the return of the ball to the playfield and signals the game microprocessor to stop the rotation of the wheel and to add the appropriate point value to the player's score.

  • Patent number: 5351954
    Abstract: The play feature of the invention includes an electromagnet mounted below the playfield on a reversible screw. The screw is rotated to propel the magnet along its length relative to the playfield. A pinball disposed on the playfield is attracted by the magnet such that the ball will be dragged across the playfield as the magnet is propelled by the screw. Optical switches are used to provide feedback to the game's microprocessor indicative of the status of the play feature. In the preferred embodiment, the game player attempts to strike the ball as it is dragged across the playfield to put the ball in play and create multiple ball play.

  • Patent number: 5226653
    Abstract: The play feature of the invention consists of a three level target assembly where the uppermost level is mounted on a section of the playfield. The two lower levels are mounted to the underside of the playfield section such that upon activation of the play feature's drive system, the playfield section is raised to sequentially expose the two lower levels. In the preferred embodiment, the upper level includes ball ejector holes, the middle level includes button targets and the lower level includes ball diverting chutes. The game's microprocessor can be programmed to allow the ball ejector holes to eject the trapped ball only after the player completes a predetermined series of shots using a second ball. In such a situation, the ejection of the trapped ball will result in multi-ball play where more than one ball is in play at the same time.

  • Patent number: 5120058
    Abstract: A dual-path ramp for pinball games is formed of a single plastic member and has a plurality of entrances from the game playfield and exits back onto the playfield. The geometry of sides of the ramp is such that the ball, as it travels adjacent to one of the sides, is directed into a plurality of patterned grooves in the bottom surface of the ramp, which, in turn, direct the path of the ball back to the sides in a criss-cross pattern. In a second embodiment, ball guides, rather than grooves, are used to cause the ball to follow one side or the other of the ramp instead of criss-crossing back and forth.
