How it works

  1. Press Start, then hold down on the board and draw one loop around the centre dot.
  2. It ends by itself after a full turn. If you let go early it ends there; if the ends do not meet or a rule is broken, you will see why and can draw again.
  3. Circle accuracy = 100 − (how far, on average, your line strays from its own average distance to the dot, in %). There is no time limit.

About this test

The circle test shows how faithfully your hand follows the shape in your head. Circle accuracy measures how far your line strays from a circle centred on the dot, so it rewards both roundness and centring (drawing off-centre lowers it). The formula has the same form as a published circle game (drawtheperfectcircle.com), but we measure evenly along your line rather than at the points you drew.

Tiers are set by your top % alone. A result exactly on a boundary gets that tier. There is no verified player distribution for Statgon circle scoring, so this is a provisional table based on other sites’ guidance and our own assumptions. It is not a checked ranking among real players. We are preparing anonymous aggregation (nothing is collected yet).

FAQ

How reliable are the percentile and tier?

They are provisional. There is no verified player distribution for Statgon scoring, so the table is based on other sites’ guidance and our own assumptions. They are not checked rankings among real players. Circle accuracy itself is a direct measure of your line.

How is circle accuracy calculated?

We measure the distance from the centre dot to your line evenly along the line, then subtract from 100 how far, on average, that distance strays from its own average, in %. Straying 5% on average gives 95%. The gap between the end and the start is closed with a straight line and measured too.

I drew well but it asks me to draw again.

You draw again if the line leaves the board, comes too close to the dot, goes backwards too far, does not complete a turn, leaves a large gap between the ends, or is too small or too fast. The reason appears under the board.

Do angular shapes score high too?

They can. Only the distance from the centre dot counts, so shapes with an even radius, like a regular octagon, score high. Smoothness is not measured separately.

Can I play with a keyboard?

No. The test measures a line drawn by hand, so you need a mouse, touch or pen. Start, close and retry work with a keyboard.
