Chess Clock
A two-player chess clock with increment. Bullet, blitz, rapid and classical presets. Tap or press Space to end your move.
Time control 5 min, no increment. Space or a tap ends a move.
How to use the chess clock
- Choose a time control, such as Blitz 3+2 (3 minutes each, plus 2 seconds per move).
- Black taps their clock, or presses Space, to start White's clock.
- After each move, tap your own clock. The increment is added to your time.
- When a clock reaches zero, that player has lost on time.
Time controls explained
A time control like 5+3 means 5 minutes for each player, plus 3 seconds added after every move (a Fischer increment). Bullet games are under 3 minutes each, blitz 3 to 10 minutes, rapid 10 to 60 minutes and classical longer than that.
On a phone, lay it flat between the players: the top clock is turned to face the player opposite. Under 20 seconds a clock turns amber, and under 10 seconds it shows tenths and ticks each second.
