Atari 800 Game: 3-D Tic-Tac-Toe (1979 Atari)

A 3D version of this strategy game where the object of the game is where you place 4 X's or O's across the 4x4x4 board in either vertical, horizontal, or diagonally. There are 9 games where the first eight games are a human player against the computer opponent. Games 1-8 are based on skill level and game 9 is a two-player game. Only played on game 1. The higher levels are just too difficult to beat.
