On this board, the Rook can bring any 1 (one) other friendly piece along with it, but the player must balance the other piece atop the Rook and push the Rook along the board to its destination. The Rook may at no point leave the game board. If the carried piece falls off at any point, it is forfeit. The player must also imitate the noise of any internal combustion engine while moving the Rook.
