How Shape Accuracy is Calculated
For circles, the game analyzes your freehand drawing by calculating the mean deviation of every point from the ideal radius. For polygons (square, triangle, hexagon), it uses a geometric fitting algorithm that tries multiple rotations to find the best match between your drawing and the ideal polygon. A perfect score means zero deviation from the ideal shape.
