How to play
CPS stands for clicks per second, which is simply your click count over the number of seconds. Quick rounds measure your peak, and long rounds measure stamina.
- Choose a length: 1 s, 5 s, 10 s, 30 s or 60 s.
- Click the big box. That first click starts the clock and already counts.
- Keep clicking until the time is up.
- Read your CPS. Best CPS keeps your top score for each length in this browser.
Controls
- Mouse or trackpad: click inside the box.
- Touch screen: taps count too, and two fingers taking turns is fastest.
- Time: pick the length before you start.
- Pause: the button stops the test.
Tips
- Let your palm sit on the mouse and tap with your fingertip, bending at the knuckle.
- Hold the mouse steady. If it wanders, clicks miss the area.
- On a phone, alternate two fingers.
- Take a break if your hand or wrist starts to ache. Long bursts of fast clicking are hard on them.
FAQ
How is CPS calculated?
Clicks divided by seconds. Land 42 clicks in a 5-second test and your score is 8.4 CPS.
Why didn't some of my clicks count?
Clicks that arrive within 20 milliseconds of the previous one are discarded. A human finger can't click 50 times a second, but autoclickers and failing mouse switches can. When the test sees a lot of those, it still shows the score but won't record it as a best.
Is there a leaderboard?
No. Bests are kept on your device only, and nobody else's scores are stored. For a fair contest, take turns on one mouse.
Does the CPS test work on a school Chromebook?
There's nothing to download or install, so it works in Chrome on a school Chromebook. The school's network still decides which sites load. If this one is blocked, ask a teacher or the IT team, and skip proxy or unblocker sites, which break school rules and often carry malware.
