Modern draughts (also called Killer Light) is a variant of Dame
(International Draughts). The only difference is the following: in a
capture sequence (but not single piece capture), if the last captured
piece is a Dame (King), 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 three Dames will win against a lone Dame.
Note that, unlike in Killer Draughts, the halt rule is not valid at
single piece capture.
