How it works
- Choose the number of players (2 to 6), the starting time per player and an optional increment in seconds.
- Press Start. The first player's clock runs down. When you finish your turn, press Next turn.
- Use Pause for a break or a rules discussion, then Resume. Each tile shows time left, time used and turns played.
- When a player's time runs out, the clock stops and shows who lost on time. Press Reset to play again.

Questions
- How does the increment work?
- The increment, also called Fischer increment, is added to your remaining time each time you finish a turn. With 5 minutes and a 3 second increment, ending a turn after 10 seconds leaves you 4:53 instead of 4:50.
- How accurate is the timer?
- Time is measured against the browser's monotonic clock, not by counting ticks, so a busy device may refresh the display late but never loses time. Under 10 seconds, tenths of a second are shown.
- What if my phone locks or the tab is hidden?
- The elapsed time is still counted correctly when you come back, because it is computed from timestamps. Keep the tab open, though: some phones freeze pages in the background, and the clock cannot notice a flag falling until the page wakes up.
