Jumping Chess is a chess variant played on a 10x10 board The rules are similar to those of orthodox chess, except that pieces capture by jumping over opposing pieces, as in Checkers or Draughts. The standard orthodox chess array is used, but in order to avoid uncapturable pieces at the edge of the board, two extra ranks and two extra files of edge squares are added. These edge squares can only be entered as the result of a capturing jump, and pieces sitting on them are obliged to capture if possible. The object of the game is to capture the opposing King, not to checkmate it. This game won the Chess Variant Pages 100 Square Contest.
