The Turret moves like a queen, but it cannot capture in this way. Instead the Turret, when it moves, has the power to sling a piece located immediately behind itself to a forward square in the alignment direction. The slung piece, which can be of any colour, is hurled to the square immediately forward of the square on which the Turret stops. Any enemy piece positioned here is captured. Thus the Turret can be used for transporting friendly pieces, attacking enemy pieces, or removing enemy pieces from good positions. Even the king can become a dangerous attacking piece together with the Turret. In opening and middlegame it introduces new tactical themes. In the endgame it can transport friendly pawns and the friendly king over the board. It can create a double attack along a diagonal and an orthogonal. Pawns can be catapulted to their promotion square, when they are promoted to queen as only alternative. Pawns cannot be catapulted to the first rank, that is, the second rank is the limit. Kings and rooks retain their castle rights if catapulted away and back, while they haven't moved by their own accord. Other rules are the same as in standard chess, except for the possible promotion to Turret.
