How to play Reaction Time
- Start the game and wait for the green GO cue.
- Tap the cue or focus the button and press Space as soon as it changes.
- An early response restarts that trial without recording a time.
- After five valid trials, compare your average in milliseconds.
A useful way to practice
Read the current rule before reacting. Device latency, input method, distractions and familiarity can all change a result. For fairer comparisons, use the same device and avoid treating a score as a diagnosis.
What your result means
This is a recreational attention activity. Results describe performance on this particular task, with this device and these rules. They are not a clinical assessment, IQ score or promise of improvements in daily life. Your best result and recent sessions stay in this browser; no account is required.
Is Reaction Time free?
Yes. You can play the full activity without a payment, download or account.
Can I use a keyboard?
Use Tab to focus buttons and Enter or Space to activate them. Answer fields accept normal typing. The maze also supports arrow keys. Timed tests will differ between touch, mouse and keyboard input.
Why did my result change?
Practice, a different generated puzzle, distractions and input timing all affect results. Compare several sessions rather than drawing a conclusion from one attempt.
