The free online mouse test.
A complete mouse tester that works without install — press a button on your mouse below to see it light up, then dig into polling rate, click speed, chatter, scroll and DPI. No download, no sign-up, just readings you can trust.
Most popular tests
Detected a keyboard input (—) instead of a mouse button. If that happened when you pressed a mouse button, it's remapped to a key or macro in your mouse software — so it won't register as a button here.
- Hover your cursor over the mouse illustration, then press each button on your mouse and check if it lights up.
- Point your mouse cursor at the mouse illustration and then spin the scroll wheel on your mouse up and down.
- Check if the arrows on the illustration also light up.
- Right-click and the side buttons are captured here, so they won't open the menu or navigate the page.
- A single middle (wheel) click toggles a locked highlight — click it again to release.
All tests
Polling Rate
Measure real report rate (Hz) from raw coalesced pointer samples.
Click Speed
Clicks per second over a fixed window — the classic CPS test.
Double-Click
Catch switch chatter and unintended double-fires.
Buttons & Scroll
Verify every button and the scroll wheel on an interactive diagram.
DPI Analyzer
Estimate CPI from a measured physical move (pointer-locked).
Scroll Wheel
Check scroll up, down, speed and the wheel click for skips.
Mouse Accuracy
Click random targets for an accuracy % and time per target.
Mouse Skip
Detect cursor jumps and skipping against your motion baseline.
Kohi Click
The 10-second CPS test made famous by Minecraft PvP.
Jitter Click
Measure jitter-clicking speed in clicks per second.
Butterfly Click
Two-finger butterfly clicking CPS over a timed window.
Drag Click
Burst CPS from the drag-click technique.
Right-Click
Right-button CPS and a quick reliability check.
Spacebar Counter
Count spacebar presses per second with a precise timer.
Mouse skill games
Free browser games to train and benchmark your mouse skills — a reaction time test, aim trainer, Super CoreBall, tracking test, bounce ball and flick shot trainer. Pair them with the CPS test above to see how click speed translates into aim.
Reaction Time
How fast can you click when the signal fires? Measures true reflex time.
Aim Trainer
Click randomised targets as fast as possible. Pure precision, no spray.
Tracking
Keep your crosshair on a moving ball. Tests smooth mouse control.
Super CoreBall
Fire balls onto a spinning core without hitting the orbiting ones. 20 levels, 5 tiers.
Bounce Ball
Chase a bouncing ball that speeds up every 5 seconds. Can you keep up?
Flick Shot
Snap to targets that appear anywhere on screen. Pure flick speed.
