How to play Chess

  1. Choose to play the computer, its level and your colour, or play a friend.
  2. Click a piece to see the squares it can move to, then click one of them.
  3. When a pawn reaches the last rank, pick the piece it becomes.
  4. Checkmate the other king to win. Stalemate, repetition, the fifty-move rule and bare kings end in a draw.

Frequently asked questions

How strong is the computer?
Easy makes plenty of mistakes, which suits beginners. Medium plays sensible chess. Hard thinks for up to two seconds a move and will punish loose play.
Are all the rules included?
Yes: castling, en passant, promotion to any piece, check, checkmate and stalemate, and draws by repetition, the fifty-move rule and insufficient material.
Can I take back a move?
Yes. Undo takes back your last move (and the computer's reply).
Can two people play?
Yes. Choose "Two players" and use Flip board to turn it round between moves if you like.
Is Chess free?
Yes. It's free to use, with no sign-up and nothing to install.
