How to play

• The board is a 3×3×3 cube — 27 slots. It also slices into 9 games of nine slots each (three for every axis).
• On your turn you may only play inside the active game (the glowing layer). The slot you take locks the next player into the game that runs through it, and the camera swings over there.
• If the active game has no empty slot you get a free move anywhere in the cube.
• Win by lining up three of your marks in a row — across a game, through the layers, or corner to corner through the cube. Draws are impossible: every full cube hides a line.
• Camera: drag with the right mouse button (or drag anywhere) to orbit, wheel to zoom.
