Killer draughts is a variant of Dame (International Draughts). The only difference is the following: if the last captured piece is a Dame, the captor must stop at the immediate next cell after the last jumped piece. This serves to reduce the drawishness of the game, since it means that two Dames will win against a lone Dame.

The object is to capture all your opponent's men by jumping over them, or stalemate the opponent so he has no moves. A Man can move forward, by sliding diagonally to an adjacent empty square. It may also jump over an enemy piece in any direction to a vacant square on the other side. Jumping over a piece captures it. Capturing is mandatory, and you must keep jumping and capturing as long as it is possible. You must even choose beforehand the series of jumps that captures the most men.

When your Man reaches the other end of the board, it becomes a Dame and can then move and capture forwards and backwards over any distance. It also jumps to capture, but only one Man at a time. A Dame must also choose the line that captures the most men. If a Man reaches the promotion square as part of a capture sequence, it does not promote.

The variant was invented by Christian Freeling. Tjalling Goedemoed has written a course in Killer Draughts, downloadable here.
