3D Tic-Tac-Toe

Three dimensional tic-tac-toe is just like the traditional game except that it is played on multiple levels simultaneously. In this case there are three levels. You win by getting three in a row on any level, as well as up, down, and diagonally across the different levels.

The handicap game disables the center position on the middle level because the player claiming this square often has an unfair advantage.
