The Perfect Circle

Click and hold to start drawing. Move your mouse in a circular motion. Release to complete the circle. Aim for a perfectly round shape with minimal deviation from the average radius.

The Perfect Line

Two dots will appear on the canvas. Click and drag to draw a line connecting them. Keep your line as straight as possible and ensure it connects both dots accurately.

The Perfect Angle

A horizontal reference line and a rotating line will appear. Click and drag to rotate the line. Your goal is to align the rotating line to exactly 90 degrees (perpendicular to the horizontal line). The angle accuracy is measured to 0.01 degree precision.

Score Calculation

Formula: (Precision × 80% × 100) + (Time × 20% × 100)

Precision is the most important factor. A slow but perfect shape scores higher than a fast but sloppy one.

Precision: Measured by deviation from the ideal shape. Smaller deviations result in exponentially better scores.

Time: Each game has an ideal completion time. Finishing too quickly or too slowly reduces the time score.
