  • Patent number: 4609359
    Abstract: An educational game for developing recognition skills regarding items of significance on a map, the map being any generally two dimensional depiction of a system (e.g. geological, astronomical, etc.). A map has a selecting electrode and a plurality of selectable electrodes, each selectable electrode being associated with one and only one item of significance on the map. A player draws a card from a deck of cards. The card bears a code and the name of an item of significance on the map. The code refers to a setting for a multiple pole, single throw switch. The switch is adapted to bring the selectable electrodes individually into an energizing circuit. The player sets the switch according to the code and then attempts to locate the named item of significance by contacting the selecting electrode with the selectable electrode associated with said item. If the player's choice is correct an indicator is energized. Optionally, a push button switch must be depressed before the indicator is energized.
