ThinkFun Solitaire Chess
Everyone knows the best part of Chess is capturing your opponent's pieces.  Solitaire Chess makes the best part the whole point.  Players get 10 pieces, two each of the Knight, Rook, Pawn and Bishop, one each of the King and Queen, and 40 challenges.  Set pieces on the board according to the challenge cards, and proceed to capture each one, but only by using the same moves allowed in traditional Chess.  Players have to capture a piece with every move, so the game is fast-paced and always exciting.  Ages 8 to Adult.
