Tic Stac Toe is a three-dimensional version of Tic Tac Toe, with the players alternately placing Xs and Os on a playing area that measures 3x3 or 4x4 depending on how players construct the game board. Players can place one piece on top of another one, up to a maximum height equal to the length of the game board. Whoever first achieves a row of three or four identical pieces – again depending on the size of the game board – wins. Reimplements 3D Tic Tac Toe Score Four
