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?

Yes. PlayMemorize is a Progressive Web App, so Perfect Shape keeps working without a connection once the page has loaded.
