Position 3 of your pieces in a row anywhere on the three-dimensional 3x3x3 game board. Players alternate turns placing their pieces until one achieves a run of 3 or the board fills up without a winner. If the board fills up, the second player wins the game.
You can either place a new piece in an empty square, or push existing pieces toward the back of the cube, as long as the row you push isn't full. Rotate the board using your arrow keys or W, A, S, D to play on any side of the board.
Nine "neutral" black pieces start on the board as obstacles, placed in a random pattern generated each time you play. Use these to block your opponent or secure advantageous positions for your pieces. You can also place three neutral pieces throughout the game (1 per turn) in addition to your normal move. These placements cannot push existing pieces, and must be placed on an empty square.
Hope you enjoy!
