Three D Tic Tac Toe

3D Tic-Tac-Toe is one of several 3-dimensional tic-tac-toe variants created for early computer systems.

In this 1-player versus computer game, the player competes on a 4 x 4 x 4 3-dimensional board. The player and computer take turns placing a piece on the board, with the goal of placing 4 pieces in a row either on the x, y, or z axis, or placed upon an angle.

The game also allows a simpler 4x4 2-dimensional board for beginners.
