This plays similar to normal chess, but with some changes. - No checkmate. The machines win by getting three pieces to the other side of the board. The minirobots win by preventing that. The "kings" can be taken. - The minirobots' pawns promote to machine gunners, who behave like a knight mixed with a short range queen. - The machines' queen can only move four squares. - The machines' rooks can only move four squares. - The machines' bishops can only move three squares, but can only be taken by bishops or while within three squares of sonar bot. - The machines' knights can take their own pawns. - The machines' king can spawn pawns on the spaces in front of itself.
