Frequently Asked Questions
What is considered a good human reaction time?
The average human visual reaction time is around 250ms. Scores under 200ms indicate elite esports-tier reflexes, while 150ms approaches the biological threshold of human nerve transmission.
What happens if I click too early?
Clicking before the screen turns green triggers a 'Too Soon!' penalty and requires restarting that trial.
Does my monitor's refresh rate affect my score?
Yes. A 144Hz or 240Hz gaming display updates frames 2–3 times faster than a standard 60Hz screen, reducing visual display latency by approximately 8–12 milliseconds.
