About Perfect Split
Perfect Split tests how accurately you can divide an irregular shape in half. Draw a straight cut or adjust its angle and position with the sliders. Area mode compares the two visible regions. Weight mode uses the shading to make one side denser than the other.
How to play
- Choose Area or Weight mode before starting your collection.
- Drag a line across the shape, or set the angle and position sliders.
- Press Make cut if you used the sliders, then read the split percentages.
- Retry freely and keep your best cut before moving to the next shape.
Scoring and challenges
An exact half earns 100 points. Your best cut on each of five shapes counts toward a total of 500. Weight mode measures the modeled density as well as the geometric area.
