A three-dimensional version of checkers. There are three stacked 6x6 boards and each player begins with 18 men. Men can move up or down to an adjacent board in addition to the usual checkers moves, and the object of the game is to eliminate all the opponent's men. This game is one of a series of three-dimensional traditional board game variants published by Tara Toy Corp.: others in the series were Tri-Chinese Checkers, Tri-Gammon and Tri-Tac-Toe.
