Measuring CPS: what the test actually does
CPS stands for clicks per second. The test measures how fast you click with a mouse, either over a fixed time span or, the other way around, as the time it takes to reach 100 clicks. It is common among players of shooters and similar games, where a high click rate helps with firing or fast building, but it works just as well as a short reaction test with no game attached.
What people use the CPS test for
- Gaming prep: Players of games like Minecraft PvP or shooters use it to check their click rate, often before switching to a different mouse or a new click technique.
- Comparing with friends: The global leaderboard makes your score comparable to others, with no account and no sign-up needed.
- Mouse check: A score that is suddenly lower than usual can point to a problem with your mouse, such as double clicks from a worn-out switch.
How a run works
- 1 Pick a variant: a fixed time span from 1 to 60 seconds, or "100 clicks".
- 2 Click inside the game area, the first click starts the timer.
- 3 Keep clicking as fast as you can until time runs out or you reach 100 clicks.
- 4 Check your result and, if you like, add it to the leaderboard with a nickname.
What sets this test apart
Measurement runs on performance.now() and real pointer events, not a coarse timer. When you submit a score, your browser sends the full click sequence along with it, the server recomputes the value itself, and it discards implausible results, such as those from autoclickers. That makes the leaderboard more meaningful than one that just trusts whatever the browser reports.
