Frequently Asked Questions
What is a good reaction time?
The average human reaction time to a visual stimulus is 200-300 milliseconds. Anything under 200ms is considered fast — competitive gamers often score 150-180ms. Reaction time is influenced by age, sleep, alertness, and practice. Regular testing can help you track improvements over time.
How can I improve my reaction time?
Practice regularly with reaction time tests, get adequate sleep (7-9 hours), stay hydrated, and minimize distractions during testing. Physical exercise and hand-eye coordination games also help. Our reaction test offers three difficulty levels so you can progressively challenge yourself.
What is a binary clock?
A binary clock displays time using the binary number system (base-2) instead of decimal digits. Each column of LEDs represents a digit of the time — hours, minutes, and optionally seconds. Our Binary Clock Decoder game teaches you to read binary time with an interactive tutorial and streak-based challenges.
Are these tests accurate?
Yes. All timing measurements use performance.now(), which provides sub-millisecond precision independent of system clock changes. This is the same high-resolution timer used in professional benchmarking tools. Results are comparable to lab-grade reaction time measurements.
