Title: Mathematical gameboard

Abstract: A mathematical gameboard implemented electronically for use in a variety of games having elements of chance and skill. The gameboard includes a plurality of keys having numerical values embossed thereon, but whose positive or negative value is unknown to the player. A randomizing circuit determines whether the number represented by the key pressed is positive or negative, the odds of a negative value increasing as the value of the key increases. Windows are provided to display a player's score and the number of plays he has made. Electronic circuits are provided to implement the use of the gameboard.
