How does a chess clock work?
Each player has their own time. After making your move, tap your own side; this stops your clock and starts your opponent's. If you set an increment, the configured number of seconds is added to your side after each move. A player who runs out of time loses (their flag falls).
Frequently Asked Questions
Why is the top side upside down?
The top clock is rotated 180° so two players can use a phone or tablet facing each other.
Which time controls can I use?
Pick from the presets (Bullet, Blitz, Rapid, Classical) or enter minutes and increment manually.
