  • Patent number: 4871176
    Abstract: A gaming apparatus for use with prerecorded media or material, such as audio or video tape, to be selectively played through a conventional player/recorder, such as an audio or video tape player, is disclosed. The play of the prerecorded material in the conventional player is controlled by a token operated unit which contains switching circuits to selectively connect the player to a monitor, such as a speaker or ear or headphones, in the case of an audio message, and a television type monitor in the case of a video message. The prerecorded material and tokens interrelated with other game paraphernalia, such as a game board, etc., as desired to provide a game which includes an audio and/or video output as part of the game engineering.

  • Patent number: 4300770
    Abstract: An electrical board game is disclosed which includes a track described on a foldable game board and having starting and finishing points and dividing into multiple parallel paths at various points along the track.The players moves a players piece along one of the multiple paths and the game detects which path was chosen by the use of electrically conductive circuitry on the board in conjunction with a conductive players piece.The game includes the ability of the players to randomly designate which of the parallel paths are safe and which are danger through the use of conductive switching elements placed on the game board in a physical orientation which determines the designation of the paths.An electronic sound generator is provided which is placed on the board and electrically responds to the players choice of path and the designation of that path, and generates either a safe or a danger sound.

  • Patent number: 4288537
    Abstract: A toy for playing a number of different games having a housing containing a sound generating circuit and a number of removable game boards providing connections to the circuit. A laminate path affixed to the board and a probe provide means for connecting a resistor to the circuit and for carrying the value of resistor to change the frequency of the sound generated. In specific embodiments the path is broken so that a graphite path defined by a pencil may connect the parts of the circuit. The path is included in each of the games as a key to the play thereof.
