How do you draw a perfect circle in this game?

Press and hold, then trace the ghost circle in one smooth, continuous stroke and release. Moving in a single steady sweep — rather than correcting mid-stroke — gives the highest accuracy score.

What is a good perfect circle score?

Anything above 90% is excellent and most players land between 70% and 90%. A score of 95%+ is leaderboard-worthy, and a true 100% is near-impossible freehand.

How is this different from other circle drawing tests?

Many viral circle tests score you against a fixed center dot. Score It High fits a circle to the stroke you actually drew (Kasa least squares), then penalizes radius wobble, incomplete arcs, and a gap where you started and finished.

Why is drawing a perfect circle so hard?

Your shoulder and wrist naturally move in arcs, not perfect curves, so keeping a constant radius freehand is extremely difficult. The perfect circle test measures exactly how close you can get.

Is the Perfect Circle game free to play?

Yes. Draw a Perfect Circle is completely free, runs in any modern browser, and needs no download, sign-up, or install.

Can I play the Perfect Circle test on mobile?

Yes. The game works on phones, tablets, and desktops — draw with your finger on touch screens or with a mouse or trackpad on desktop.

Precision drawing

Draw a perfect circle — scored on the stroke you drew

One continuous stroke, then an accuracy percentage. No ruler, no undo, no account required.

The ghost ring is a guide, not the score. We fit a circle to your path and grade how round, complete, and closed that path actually is.

How Score It High grades a circle

A lot of viral circle tests lock a dot in the middle of the screen and score you against that one point. If you draw a beautiful circle a few millimetres off the dot, they punish you. That is a center-finding test, not a roundness test.

We do the opposite. After you release, we run a Kasa least-squares fit: the circle that best matches the points you actually drew. Score then drops for three things we can measure: how much your radius wobbles, whether you covered a full loop, and how far your start and end sit apart.

A round oval that is slightly off-center can still score well. A square drawn around the ghost cannot. That is the whole point of the studio.

How to play

Press and hold, trace the ghost in one motion, and release. The percentage is geometric fidelity — 100% would be a perfectly round, fully closed loop.

Sweep at one speed. Mid-stroke corrections add wobble the fitter will see.
