Abstract
An electronic guessing game is disclosed which includes a keyboard for entering numbers, and a light and speaker for producing a variety of visual and audible signals. A prize is also provided within a transparent housing. A first player enters a secret number by means of the keyboard. A second player then enters his guess at the secret number using the same keyboard. The second player attempts to retrieve the prize by reaching into the transparent housing. The position of the players hand is detected by a group of photocells. If the player's guess is not equal to the secret number, the game will generate an error signal and the player must withdraw his hand. The closer the player's guess is to the secret number the closer he may approach the prize before the error signal is sounded. If the player guesses the secret number within a preallotted time interval, he may retrieve the prize. A mode of operation is also disclosed in which the game chooses the secret number by means of a random number generator. Thus the guessing game may be played with only one player.
