The classic CPS test
CPS stands for clicks per second, and the CPS test is the simplest possible measure of clicking speed: click as fast as you can for a fixed time, and the test divides your clicks by the seconds elapsed. Choose a 1-second burst, a 5-second sprint, or the full 10-second endurance format. The timer starts on your first click — no start button, no countdown to wait through — and stops itself the instant time runs out.
During the run, the button area shows your live click count and the remaining time ticking down to a tenth of a second, so you can pace yourself or empty the tank. After the buzzer, clicks no longer count, and the result card takes over with your CPS score to two decimals, your total clicks, and a rating badge from Amazing down to Slow.
Track your best, beat your best
The test keeps a separate personal best for each duration — sprinting and endurance are different skills, and the numbers prove it. Every finished attempt joins a local history of your last twenty tests, and the leaderboard shows your five best scores with clicks, score, and date. A new record slots into the table with a highlight.
On a keyboard, the space bar counts as a click while the timer runs, which many testers find faster than a mouse. Everything is stored locally in your browser: no account, no shared leaderboard, no data leaving your device. Refresh the page and your bests are still waiting.
Technique tips that actually raise your score
Score in a CPS test is mostly wrist and rhythm, not effort. Keep your hand relaxed and use short, low movements — lifting the finger far between clicks is the most common way to lose. On a mouse, clicking with two alternating fingers, or jitter clicking with a tense forearm, can add real speed once practiced; on a trackpad, a single fast finger usually wins.
For the longer formats, find a sustainable pace early: a sprint that dies at second six loses to a rhythm that holds all ten. Watch the live counter — if your clicks-per-second feel is dropping, slow deliberately for a beat and recover. Then take the test again; the personal best is waiting.
