Share one clock between two players

Only the active player's clock counts down. Tap that clock after a move to add the chosen increment and start the other player's time.

The clock reports when a player runs out of time. It does not record moves, validate a game or decide other results. Set a new time control after Reset.

How to use this tool

  1. Set starting minutes and increment seconds.
  2. Press Start and tap the active clock after each move.
  3. Pause for an interruption or reset for a new game.

Example

For a 5 minute game with a 3 second increment, enter 5 starting minutes and 3 increment seconds. A completed move adds 3 seconds to that player's remaining time.

Common questions

Can I switch players with the keyboard?

Press Space when focus is outside a form field or button. Tapping the active player's clock also switches turns.
