Measure activations per second in a 1, 5 or 10-second run. Use a mouse, touch or keyboard. The first activation starts the timer and is counted; your best score for each duration is stored locally when available.
How to use this tool
Choose the duration and activate the large test area repeatedly. Keyboard users can focus it and press Enter or Space; held-key auto-repeat is ignored. Wait for the final score, then activate again to retry. Hidden tabs cancel the run.
What this test can and cannot show
Scores depend on input method, device and browser timing, so compare like-for-like runs. The tool does not certify gaming skill or use population-based rankings. Local records can disappear if browser storage is cleared or unavailable. Take breaks if repeated clicking feels uncomfortable.
Updated October 1, 2026. Browser and device support varies.
Questions and troubleshooting
How is my CPS score calculated?
The final score is the number of activations divided by the selected duration in seconds. The first activation starts the timer and is included. Mouse, touch and keyboard results measure different input methods, so compare runs using the same method and duration.
Where is my personal best saved?
The best score for each duration is saved in this browser’s local storage when available. It is not an account record or a public leaderboard. Clearing site data, using another browser or blocked storage can remove or hide it.
How this tool was checked
Automated Chromium checks on October 1, 2026 verified a timed keyboard run, score output and duration reset. These checks validate counting behavior; they do not establish human speed rankings or mouse switch latency.
