FAQ
What's a good average reaction time?
Most people average somewhere in the 200-300 millisecond range, though it varies by person and device.
What does Hard mode do differently?
Hard mode occasionally shows false starts to test whether you click too early, not just how fast you react.
Can I see my progress over multiple attempts?
Yes, the trend graph and history show how your results change across attempts.
Is my score saved anywhere?
No, stats and history are kept only in your current browser session.
