MacQubic is a three-dimensional version of tic-tac-toe played on a 4 x 4 x 4 grid. Xs and Os alternate turns, fighting to be the first to place four pieces in a line. Much study has been devoted to this seemingly simple game, and Oren Patashnik, in 1977, showed that the player who goes first can in fact force a win. However, this is much easier said than done. A route to solving MacQubic is outlined in chapter four of Victor Allis's thesis. MacQubic is a deceptively easy-looking version of this game.
