How the test works
Pick 1, 5 or 10 seconds, then click the big box. The clock starts on that first click and every click, tap or key press on the box counts until time is up. Your score is the number of clicks divided by the seconds. Clicks after the end are ignored, and the box waits a moment before you can start again, so a last click does not start a new run by mistake.
What a good score is
Most people manage 6 to 8 clicks a second by tapping normally. Jitter clicking, where you tense your arm to shake the finger, reaches 10 to 14, and butterfly clicking with two fingers can go higher. A short test flatters you: 1 second is all burst, while 10 seconds shows what you can keep up.
Keys and touch
With the box focused, every key press counts as a click (held keys do not repeat), so you can test a spacebar or a keyboard switch. On a phone each tap counts, and two fingers tapping in turn count separately. Your best scores are kept in this browser's local storage, so they are there next time on this device. They are never sent anywhere; clear the site's data to wipe them.
Questions
Is the count exact?
Yes. Every press the browser reports on the box is counted once, the moment it happens, and the time comes from the browser's high-resolution clock.
Can an auto clicker cheat it?
It can. There is no leaderboard here to protect, so the test simply counts what arrives.
Are my scores saved?
Only your best for each length, in this browser's local storage. Nothing is sent anywhere.
