Frequently asked questions
What is an online chess clock?
An online chess clock is a two-player timer that runs one side at a time. Each player taps their clock after moving, which stops their time and starts the opponent's time.
What is Fischer increment?
Fischer increment adds a fixed number of seconds after a player completes each move. A 3+2 game starts with three minutes and adds two seconds per completed move.
What is Bronstein delay?
Bronstein delay waits for a fixed number of seconds before deducting time on each move. Unused delay time is not added to the player's remaining clock.
What do bullet, blitz, and rapid mean?
Bullet uses very short clocks, blitz usually gives each player three to five minutes, and rapid gives each player more than ten minutes. Event rules can vary.
Does this chess timer require an account?
No. The chess timer runs in your browser, requires no account, and does not upload your game or clock data.
