Perfect Circle: Blackboard Challenge
by kouyaiosdata
Draw a perfect circle on the blackboard and battle AI rivals! Navigate obstacles like shaky hands and tilted boards to create the most perfect circle possible. Defeat rivals across 3 rounds by achieving a higher average score than your opponent. Progress from apprentice teacher to the legendary Circle Sage across all 5 rivals. Can you defeat them all?
How to play
Drag your finger or mouse on the blackboard to draw a circle. The closer your circle matches a perfect circle, the higher your score. Complete 3 rounds of increasing difficulty: Round 1 has shaky hands, Round 2 has a tilted board, and Round 3 gives you only 5 seconds to draw. Win by achieving a higher average score than your rival across all 3 rounds. Each victory brings a stronger opponent until you face the legendary Circle Sage.
