Tap a piece to see its moves, then tap a highlighted square · pick a Difficulty level above · the computer plays the other color
Chess lets you play a full game against a computer opponent built right into the page — no account, no downloads. All the real rules are here: castling, en passant, pawn promotion, check, checkmate, and stalemate, with legal moves shown as you pick up each piece. Five difficulty levels run from a friendly club-strength opponent up to a tougher master, so beginners and experienced players each get a fair fight. The engine thinks on its own, and a clear thinking indicator shows when it's calculating. It plays with touch or mouse on phones, tablets, and computers and suits ages 8 and up — a timeless way to practice planning, foresight, and strategic thinking one move at a time.
