How is the score calculated?
We compare your drawing against a mathematically perfect circle rooted at the center of your drawing. Deviations reduce your score.
Master the Perfect Circle Game
Perfect Circle is an addictive skill game that tests your precision. Your goal is simple: draw a circle that is as round and accurate as possible.
We analyze your drawing in real-time to calculate a percentage score. 100% means geometrical perfection. Challenge yourself and see if you can beat your high score or compete with friends.
To improve consistency, practice with one stable hand posture and one fixed drawing speed. Sudden acceleration near the closing point is the most common reason scores drop below your average.
Use short rounds first, then move to full circles after control improves. Comparing weekly averages is more meaningful than chasing one lucky high score because it reflects repeatable motor control.
Practice Checklist
- Keep wrist and elbow posture consistent for each attempt.
- Start slowly and maintain similar speed through the closing arc.
- Track weekly average score rather than one peak result.
