Find visual balance before drawing
The geometric center of the screen is not always the center of the shape. Look at the object’s widest points and imagine how much colored area lies on each side of your proposed line.
Pause for a moment before touching the board. Decide both the entry and exit points first. A confident single stroke is more accurate than starting without a destination and correcting halfway.
Use symmetry as a shortcut
For symmetrical objects, identify the axis that mirrors the outline. Cutting along or perpendicular to that axis often produces equal area. Irregular shapes require balancing a wide short region against a narrow long one.
Do not rely only on the bounding box. Empty corners contain no area. Follow the actual silhouette and mentally move small protrusions from one side of the cut to the other.
Turn percentages into useful feedback
A result near 50/50 means your center estimate was strong. If one side is consistently larger, shift the next line slightly toward that side. Make a small correction; large reactions often overshoot.
Higher levels reward consistency across different silhouettes. Remember the direction and size of each correction, not the exact line from the previous puzzle. The transferable skill is estimating area, not memorizing coordinates.
