My score seems too slow / too fast — is the test accurate?
Our test uses the browser's performance.now() API for sub-millisecond timing accuracy. However, your score includes system latency (mouse, USB polling, monitor refresh rate). On a standard setup this adds approximately 5–15ms. A 144Hz gaming monitor and 1000Hz polling rate mouse will give the most accurate results.
My Clicker Tycoon progress was lost — can I recover it?
Game data is stored in your browser's localStorage. If you cleared your browser data, switched browsers, or used private/incognito mode, the save data is gone and cannot be recovered — we do not store any user data on our servers. To prevent this in the future, always play in regular (non-incognito) mode and avoid clearing site data for reactionspeedtest.com.
Can I embed your reaction test on my website?
We do not currently offer an embeddable widget. For educational or research use, please contact us through this form with details about your intended use.
How do I report a false positive in CPS / reaction test?
Use the Bug Report option in the form above and include your browser, operating system, device type (PC/Mac/mobile), and a description of what happened. A screenshot or screen recording is very helpful.
