The four tests
- CPS test — clicks per second over 1, 5, 10 or 30 seconds. Most people score 6–8 CPS; jitter and butterfly clickers reach 10–15+. Your best score is saved in this browser.
- Reaction time — 5 rounds, averaged. Typical human visual reaction is about 200–270 ms; your monitor and mouse add a few milliseconds.
- Double-click test — catches worn mouse switches that register one click as two. A gap under 80 ms between clicks of the same button is flagged.
- Polling rate — how many position updates per second your browser receives while you move the mouse, rounded to the nearest standard setting (125–8000 Hz).
About the polling rate result
Browsers report what they observe, not the mouse's hardware setting directly. Move the mouse quickly and continuously for a few seconds for a stable reading. Chrome and Edge use high-precision raw events; other browsers may cap the rate, especially above 1000 Hz. Use it to compare settings or spot an unstable connection.
Frequently asked questions
What's a good CPS?
6–8 CPS is typical with normal clicking. Over 10 CPS usually means jitter clicking or butterfly clicking; Minecraft PvP players often train for this.
My mouse double-clicks on its own — what can I do?
That's usually a worn switch. Try compressed air, check for a firmware "debounce" setting in your mouse software, or replace the switch. If the mouse is under warranty, the test result is good evidence.
