Cube-Tac-Toe is a game of strategy. Two players build a CUBE, made up of 27 small cubes, from the ground up, competing for Cube-Tac-Toe points as they build. Three in a row is a Cube-Tac-Toe point. The player with the most Cube-Tac-Toe points is the winner. —description from the instruction sheet Published in the early 1980s by Rhombics, a maker of wooden puzzles, the pieces are made out of light Maple and dark Walnut.
