Play Last Piece — Chess Capture Puzzle

Hints cost 10 coins

Last Piece is a one-player chess puzzle where every move is a capture. Pieces move as they do in chess, any piece may take any other, and pawns capture diagonally up the screen. Clear the board down to a single piece. Later tiers limit each piece to two moves or insist that the king survives. Sixty boards grow from four by four to six by six, with a daily board.
