Chess Puzzle is a free online chess tactics trainer you can play right in your browser — no sign-up, no download. Each puzzle drops you into a real position with one best line to find: spot the tactic and play every move in the sequence. Build a solving streak, chase your best puzzle rating, and skip any puzzle that has you stuck.

1. Study the position — the prompt above the board tells you which side moves.
2. Tap a piece, then tap a highlighted square to make your move.
3. Only the best move counts; the opponent replies automatically.
4. Play the full sequence to solve the puzzle and extend your streak.
5. Wrong move? Your streak resets, but you can try again — or skip.

💡 Tip: Scan forcing moves first — checks, captures, and threats. Most puzzles hinge on a move your opponent can't ignore.
