Reaction Time Test Unblocked
This page opens the classic reaction time test as a simple web page. There's nothing to download and no account to create, so it opens on most school and work devices, including Chromebooks.
The screen turns red; wait. The moment it turns green, click, tap or press Space. Five rounds give you an average, a fastest and a median time in milliseconds.
Why it opens almost anywhere
- It's a single lightweight HTML page – no plug-ins, no Flash, no installer.
- No sign-up and no third-party login.
- Results are saved only in your browser.
- Works with mouse, keyboard or touch.
Tips for an accurate result
Use a wired mouse or the Space bar if possible – some wireless devices add a little delay. Close other heavy tabs, sit comfortably and look at the centre of the screen. Don't try to predict the change; the wait is random, and clicking early resets the round.
