Test your sense of spatial relationships with this reverse jigsaw puzzle. Instead of putting things together, you use your finger to slice 2-D shapes into equal-size parts. Slicing a square in half: easy. Using three cuts to divide an irregular blob into seven pieces, all with the same area: Good luck.
WIRED First slice can be a hint if you get stuck. Has 200 levels to keep the challenges coming.
TIRED Free on Android only because of ads. No way to save solutions.
