Online chess clock
A free chess timer for games over the board — blitz, rapid or classical, with increment or delay. Put your phone between you and press your side after each move.
Tip: press Space to switch sides and P to pause. On a phone, lay it between the players — the top clock is upside-down for your opponent.
Chess clock questions
How do I use an online chess clock?
Choose a time control and put the phone or laptop between the two players. Press your own side right after you move: that stops your time and starts your opponent’s.
What is increment in chess?
Increment (Fischer) adds a fixed number of seconds to your clock after every move you make. “3+2” means 3 minutes each plus 2 seconds per move.
What is the difference between increment and delay?
With delay, your clock waits a few seconds before it starts counting down each move, but unused delay is not added to your time. With increment, the seconds are always added.
Which time control should beginners use?
Rapid controls such as 10+5 or 15+10 give enough time to think. Blitz (3+2, 5+0) and bullet (1+0) are fast and best once you know the basics.
