Please don't advertise in the comments, but getting into arguments over ads is not constructive either. Draw a circle while staying as close to the template as possible. ⚠️ If it says "Not a circle", you made the circle too quickly or you didn't close it all the way. When you're done, release your mouse. It will show a graph of the distance from the actual circle over the time you drew it. (lower is better, it's not a percent scale) My best score is 2.95!
Update Oct 8 2026 - Thank you to whoever featured this project!!!!!!!!!!!!!!! I opened my chromebook at school today and had 2000+ messages! When I started Scratch over 7 years ago, I had no expectation that any of my projects would get popular, let alone featured! I'll do my best to respond to comments, but some will probably slip through the cracks. I have added a personal best I was inspired by my friend @notmyreainame2: https://scratch.mit.edu/projects/1384790384/ The neal.fun website is what popularized this perfect circle type of game. The pencil, arrows, and font is from the Scratch library, but everything else is by me. If you are wondering exactly how it works, @Xenochro phrased it well: It calculates the distance between the mouse and the origin. Then, it finds the difference between that value and the circle's radius. It does this for every point on your circle, and then calculates the average, which becomes your score. #games #art
