About the game
Tic-tac-toe on a 4×4×4 cube: plane lines count, depth columns count, and so do the diagonals that cross the whole cube. There are 76 winning lines, which is why draws barely happen here.
How to play
Rotate the cube with the mouse and click a cell. The AI answers, and it does watch the diagonals.
