Last Chessman Standing:
Invented by Vesa Timonen. Have the pieces capture each other until there is only one. No moves, only captures.

How to Play.
Click and drag a piece onto another to capture it. Pieces capture as in standard chess, but color can be ignored. When the button is held on a piece, the legal captures will turn black. You'll be notified if there are no more moves.
