  • Patent number: 4432733
    Abstract: An amusement game formed by a base having a well therein to receive a power source, such as a battery, and a platform on which a pre-printed circuit card of conductors is located with the card having an upwardly bent portion which extends over a corresponding portion on the base and which also carries a plurality of light emitting diodes. A cover overlies the printed circuit card with the cover having a cutout providing access to a plurality of pairs of terminals of the printed circuit each of which is designed to activate an LED with a activating card having conductive material thereon to cause a corresponding pair of terminals to be activated.

  • Patent number: 4310318
    Abstract: An electronic game made from a single piece of material on which conductive ink is printed on a first section of the piece with a pattern of two sets of closely adjacent lines each with a connecting terminal for one terminal of a battery. On the first section, a light emitting diode is mounted which is connected in series with one set of lines and one of the battery connecting terminals. A hole is provided in the second section of the piece through which the light emitting diode can be viewed and an overlay with electrically conductive areas thereon is cut from the second section. The two sections of the piece are folded together with the battery connections from the first section extending through slots in the second section and a battery is connected to the battery connections with the light emitting diode being viewable through the opening.
