Chess Clock
A two-player chess clock with blitz and rapid presets — tap to switch.
Tap a player's panel to start the opponent's clock. After that, the player on the move taps their own panel to bank the increment and pass the turn. Changing the time control resets both clocks.
How to use the chess clock
- 1
Pick a time control — for example 5+0 blitz, 10+0 rapid, or 15+10 with increment.
- 2
Each player gets their own clock; only one runs at a time.
- 3
After your move, tap your side of the clock — that stops yours and starts your opponent's.
- 4
If a clock reaches zero, that player has run out of time and the game is over.
- 5
Use Pause to stop both clocks, and Reset to start a new game with the same control.
Tips & tricks
A chess clock is two timers that are never running at the same time. Tapping your side hands the turn — and the ticking — to your opponent. The discipline of pressing the clock after every move is part of timed play.
Increment time controls (the +5 or +10) add a few seconds back to your clock after each move, which keeps fast games from being decided purely by who can tap quickest near the end.
It works for more than chess — any two-player turn-based game benefits from a shared clock. Keep it in fullscreen between two players for a clear, glanceable board.
Frequently asked questions
How does an online chess clock work?
It shows two clocks, one per player, and only one runs at a time. After your move you tap your side, which stops your clock and starts your opponent's.
What time controls are supported?
Common blitz and rapid presets like 5+0, 10+0 and 15+10, plus the ability to set your own base time and increment.
What is increment?
Increment is a small amount of time — for example 5 or 10 seconds — added back to your clock after each move. It is the "+" in a control like 15+10.
What happens when a clock hits zero?
That player has run out of time. The clock stops and clearly shows whose time expired.
Can I use it for other games?
Yes. Any two-player, turn-based game can use a shared clock — chess, checkers, Go, or casual games.
Is the chess clock free?
Yes — free, no sign-up, works on phones and tablets.
