About Perfect Circle
Perfect Circle is a simple yet challenging game that tests your hand steadiness and precision. Drawing a perfect circle freehand is surprisingly difficult, requiring a steady hand, good eye-hand coordination, and spatial awareness.
The game uses advanced algorithms to analyze the shape you've drawn, comparing its roundness, consistency, and closure to that of a mathematically perfect circle.
Challenge yourself or compete with friends to see who can draw the most perfect circle!
