Color/3D Tic Tac Toe

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

In this 2-player versus computer game, each player takes turns placing a piece on a 3 x 3 x 3 tic tac toe board. The board is represented by a series of 9 pegs, and the player uses the keyboard to state which peg and the location (top, middle, or bottom) to play each piece. A player can win by playing 3 in a row in either the x, y, or z axis.
