Chess Clock

About the Chess Clock

A browser-based two-player turn timer built for any timed board game. It runs two independent countdowns and switches between them on each tap — the moment you finish your move, tap your panel to stop your clock and start your opponent's. Supports Fischer increment, Bronstein delay, a live move log, and presets from Bullet to Classical. A 3-second animated countdown launches each game; on mobile, the top panel rotates 180° so each player reads their clock right-side up from across the table.

No app install, no account needed. Just set your time control and tap.

How to Use on GameNight.pro

• Set your time control: Pick a preset from the Time Controls bar — Sudden Death, Fischer, or Bronstein — or use Custom Setup to set any minutes, seconds, and increment amount.
• Choose who goes first: Use the Who Starts? toggle to select White or Black. That player's clock runs immediately after the countdown.
• Tap to start: Tap either clock panel. A 3-second countdown fires, then the first player's clock begins.
• Tap your panel when done: The glowing panel is yours. Tap it the moment you finish your move — your clock stops, your opponent's starts.
• Pause or reset: Hit Pause to freeze both clocks. Reset appears while paused and returns to setup. Keyboard shortcuts: Space taps the active clock, P pauses, R resets.

Time Control Types

• Sudden Death: Each player gets a fixed pool of time — use it all and you flag. The simplest format, popular for casual blitz. Set Inc. Type to None.
• Fischer increment: A fixed number of seconds is added to your clock after every move, regardless of time spent. Rewards speed without punishing deliberation. Notation: 10 | 5 = 10 minutes + 5 seconds per move.
• Bronstein delay: Time is restored after each move but only up to the amount actually spent — you can never accumulate extra seconds. Rewards efficient play without the time-buildup effect of Fischer.

When to Use a Chess Clock

• Any two-player game that drags: A shared clock turns Scrabble, Checkers, or Backgammon from marathon sessions into snappy rounds. A 2-minute time control fixes slow players without an argument.
• Teaching chess to a beginner: Set an asymmetric control — 15 minutes for the learner, 5 for the experienced player — so both sides feel equally pressured.
• Running a club night or tournament: Presets cover every standard format from Bullet to Classical. Reset between rounds in one tap; the move log provides a time record for any disputes.
• No physical clock available: Place a phone face-up between players — audio cues cover every tap so neither player needs to glance at the screen to know whose clock is running.
