Hayden Announces Tetrad: A New Way To Play Tic-Tac-Toe
Tetrad is a game of strategy and mental daring that enables a player to match wits against a computer. Based on the popular game of Tic-Tac-Toe, Tetrad allows the tension to build between opponents as each tries to get four X's or O's in a row in any direction on any or all four playing boards.
Tetrad has a board that offers 16 squares on four different levels. The additional squares and boards allow 76 possible winning combinations — nine times more than conventional, two-dimensional Tic-Tac-Toe.
Players can choose from three levels: novice, intermediate or professional. Colorful graphics accompanied by unique sound effects make Tetrad a new way to play an old favorite.
Tetrad is written by Philip Hess and can be used on an Apple II disk with 32K, 09809, $19.95.
