Chess Clock

Yes. The chess.lc chess clock is 100% free, runs entirely in your browser, and requires no install, no signup, no account, and no credit card. There are no daily limits — use it for as many games as you want.

No. The chess clock runs entirely in your browser using JavaScript. No app store install, no extension, no executable, no Chrome flag. Open the page on any device — phone, tablet, laptop — and you can start a game in one tap.

Built-in presets cover the seven most-played time controls: bullet (1+0), blitz (3+0, 3+2, 5+0, 5+3), and rapid (10+0, 15+10). These match the standard rated controls on Chess.com, Lichess, and chess.rodeo, so the times feel identical to your online games.

Yes. The 3+2, 5+3, and 15+10 presets add Fischer-style increment after every completed move. The notation X+Y means X minutes base time plus Y seconds added back to your clock each time you tap your side. Increment prevents pure time scrambles in winning positions.

Tap your own clock (or press the spacebar on desktop) to stop your timer and start your opponent's. This matches a physical chess clock — you press your side after you move, not your opponent's. If the game has not started yet, the first tap on either side starts White's clock.

Yes. The two-clock layout is fully responsive and works in portrait orientation on phones. The tap-to-switch interaction is optimized for touch screens — no double-tap, no long-press, no precise targeting required. Use it on the same device you play board games with friends on.

Yes. The Pause button stops both clocks immediately. Press Resume to continue with the same remaining times, or Reset to restart the game with the original preset. Useful for over-the-board games when someone needs a quick break.

For free Stockfish analysis with no daily cap, paste your PGN into chess.rodeo — it's free, no account required, and runs the same engine that powers top-tier game-review features. Useful for post-mortems after blitz or rapid games on the chess.lc clock.
