Mouse Spin Test
Move your mouse in circles inside the ring and this test turns the motion into numbers: total spins, your current speed in RPM, your peak speed, and the total degrees you have turned through. It is mostly for fun, but spinning fast is also a quick way to see how cleanly your mouse sensor keeps tracking at high speed. Try free play, or take the five-second challenge for a score and a rank.

What a mouse spin test measures
A mouse spin test tracks the angle of your pointer around the center of the pad and adds up how far it travels, so circular motion registers as rotation. It reports the total number of full turns (spins), how fast you are spinning right now in RPM, your peak speed, and the total number of degrees you have turned through. Because it responds to fast circular motion, it doubles as a rough check that your sensor keeps tracking cleanly at speed — for a fuller button and scroll check use the Mouse Tester, and to measure your real sensitivity try the Mouse DPI Analyzer.
How RPM and spins are calculated
RPM stands for rotations per minute. As you move, the test measures the small change in pointer angle between updates and sums those changes over a short rolling window, ignoring tiny jitter near the center where the angle is unstable. Dividing the degrees turned in that window by the elapsed time gives an angular speed, which is converted to rotations per second and then multiplied by sixty for RPM. One full spin is 360 degrees, so total spins is simply the total degrees turned divided by 360. The reading is smoothed slightly so a single stray sample does not spike the number.
Spin-outs and perfect control speed
A spin-out is when you whip or spin the mouse so fast that the sensor briefly loses tracking and the cursor jumps or stalls. Every optical sensor has a maximum speed it can follow, often quoted in inches per second (IPS); move faster than that and tracking breaks down. Your perfect control speed is the fastest you can move while the sensor still reports every step accurately. Spinning here at high RPM without the trail glitching or the counter freezing is a sign the sensor is keeping up, whereas sudden jumps or a stalled count can mean you have exceeded its tracking limit.
Tips for more spins
- Hold the mouse loosely with your fingertips so your wrist and fingers can whip it around in tight, fast circles.
- Keep the circles small and centered; large sweeps cover more distance but take longer to complete a full turn.
- A lower DPI gives finer, more controlled circles, while a higher DPI makes each motion sweep further — both can help depending on your style, so try each.
- Use a smooth, low-friction mousepad with room to move so the sensor stays in contact and glides.
- Warm up first, then take the five-second challenge; a steady rhythm usually beats a frantic one.
