FAQ
What if I tap too early?
The round isn't counted and restarts. The wait is random every time, so you can't time it in advance.
Do results differ between devices?
Yes. Screen refresh rate, touch latency and wireless mice can add tens of milliseconds. Compare results from the same device for fairness.
How are titles chosen?
They're just-for-fun names based on your average. They don't represent any real ranking or ability.
Where is my record saved?
Only your best average is stored in this browser. Nothing is sent to a server.
