Cut It in Half

Cut It in Half challenges your spatial reasoning by asking you to draw a single line that divides a shape into two equal areas. Shapes range from simple triangles to complex polygons, and difficulty increases as you progress.

A shape appears on screen. Draw a line through it that splits it into two halves of equal area. The closer your line is to a perfect bisection, the higher your score. You have 15 seconds per round.

How you approach bisection reveals your perceptual precision — whether you rely on intuition or careful calculation, and how you handle increasing complexity under time pressure.
