What is Perfect Circle Drawing?
Perfect Circle Drawing is a game where you draw a freehand circle with mouse or finger and score how close it is to a perfect circle. Inspired by the viral 'Circle of Truth' challenge of 2026, it analyzes the drawn circle's center point, radius deviation, and gap between start and end points, scoring out of 100.

Frequently Asked Questions
How is the score calculated?
After calculating the center point and average radius of drawn points, it measures how much each point deviates from the ideal circle. How well the start and end points connect is also included in the evaluation.
Can I do it on mobile?
Yes! You can draw circles with your finger on a touchscreen. Some say fingers actually make it easier to draw natural circles than a mouse.
Can I get 100 points?
Theoretically possible, but getting 100 freehand is nearly impossible. 90+ is truly impressive skill!
