Square Play (1984)

Square Play is an abstract strategy game played on a board of inset squares. Each player takes turns placing one of seven tokens in the hope of creating a square with four tokens. If they fail in that effort, players take turns moving a token to create either a square with four tokens or a straight line with three, whereupon they can remove an opponent's token. Play continues until either a square is formed or until a player is eliminated due to having only 2 tokens left on the board.
