Chess Chess is a free online chess game you can play right in your browser — no sign-up, no download. Play a full game as White against a built-in AI that adapts its strength to you: win consistently and it digs deeper, struggle and it eases off. Every rule is in here — castling, en passant, promotion — on a clean, mobile-friendly board.

1. Tap one of your pieces to see its legal moves highlighted.
2. Tap a highlighted square to move there — captures are marked on enemy pieces.
3. The AI answers as Black after every move.
4. Protect your king: checkmate ends the game, for either side.
5. Keep winning and the AI levels up to match you.

💡 Tip: Develop knights and bishops before your queen, castle early, and never trade king safety for a pawn.
