How is my drawing scored?

The game samples your outline's distance from its centre at every angle and compares that to the ideal shape, at the best-fitting rotation. A perfectly even, closed outline scores near 100%; wobbles and gaps lower it.

Can I draw with a mouse or a finger?

Both. Draw in one continuous stroke with a mouse, trackpad or touchscreen · whatever you have.

Is there a time limit or a way to lose?

No · it is pure practice. You get a percentage and the perfect outline to compare against, and you can redraw as often as you like.

Why is the circle harder than the square?

A circle has to be perfectly even all the way round, with no corners to anchor you, so most people find it the toughest. The polygons give your eye corners to aim for.

Does it work offline?

About Perfect Shape

Perfect Shape is a steady-hand challenge: choose a shape, draw it freehand in a single stroke, and find out how close to geometrically perfect you got · scored as a percentage. It is the kind of thing that looks easy until you try to draw a truly round circle.

How the score works. When you lift your finger, the game measures your outline's radius at every angle around its centre and compares that profile to the ideal shape · a perfectly even radius for a circle, a regular ridged profile for a triangle, square, pentagon or hexagon · trying every rotation to give your drawing the fairest possible fit. A smooth, closed, even outline scores highest.

You are never wrong. There is no fail state and no time limit. Every attempt simply shows your percentage and overlays the perfect outline in grey so you can see exactly where you drifted, then you go again.

Beat your best. Each shape keeps its own personal best, so you always have a number to chase. Circles are the classic; the polygons reward a planned, deliberate hand.
