Chess Tactics
Real positions from real games. Your opponent has just moved: find the winning move and play the line through to the end.
Chess puzzles and board games
Classic board games make some of the best puzzles. Find the winning move in real chess positions, play checkers against a computer opponent, or clear a board of marbles one jump at a time.
Every puzzle here has a clear goal and a solution you can check, with hints that show the next move when you are stuck.
Checkers
Checkers puzzles where one move wins, plus full games against the computer at four difficulty levels. English and American rules.
Last Piece
Chess pieces with no sides and no opponent. Every move must be a capture, and the aim is to leave exactly one piece on the board.
Marble Jump
Marble solitaire on a wooden board: jump a marble over its neighbour into an empty hole, remove the jumped one, and finish with one marble on the target.
