As a tip: what it's really checking is for a circle centered on the dot in the middle with the radius equal to your initial click's distance from the center. You could make a mid sized perfect circle which is slightly off the center of the dot and lose to a square that fills the play area.

I was wondering why some circles seemed great but got low scores. To test your tip, I just made a square and got 92%

Also interesting to try to get low percentages. Worst I could get was 53.1% by drawing a rectangle over my whole screen.

I got 20% by drawing an ellipse

I got 2.6 for starting close, then circling a big circle, like this https://pasteboard.co/vYFY7MSrgcoD.png

My anticlockwise circles score more than my clockwise ones. Is there some theory behind that ?

By cheating with a Python script to move the mouse, I managed to get 99.9%. Seems difficult to get higher than that, perhaps due to the mouse position having integer coordinates.

I literray came here to see who is going to proclaim automation first (and in what way) :) Unsurprinsingly, it was the first comment.

100% perfect circle is a pure math thing and can't be achieved with drawing in any way.

Another great neal.fun page. One feature I'd like to see is, make the user to N circles in a row and take the median score or something. Right now you can just spam hundreds and take your top score, but it doesn't really reward consistency.

One of my maths teachers was able to draw up to something like a three foot circle on the blackboard that looked very, very close to ideal every time. He would always use two arcs to do it and it was uncanny. He would whip out a metre/yard rule to do straight lines because they are much harder to do.

Your limbs etc are all a collection of ball and socket/downright weirdly jointed/hinges with benefits/more weirdness. You then want to use this monstrose agglomeration (did I mention how you move the bloody things?) to draw a circle? Obviously you would decide to run a finger over a simulator of a lump with a ball in it and some on/off switches.

People are weird. Nice website though.
