One shape. One target. One satisfying slice. Can you cut off exactly 30%? Or split an unusual shape perfectly in half? SliceSense turns a simple swipe into a playful test of your eye for proportions. SLICE YOUR WAY THROUGH 12 WORLDS Explore 120 campaign levels, from clean geometric shapes to fruit, forest finds, vehicles, creatures, and sweet treats. Every world has its own look, and every new shape gives you a different puzzle to judge. THREE WAYS TO TEST YOUR INSTINCTS • Classic slicing: draw a straight cut and get as close as you can to the target percentage. • Point & Slice: start from a marker around the shape and choose the right direction. • Memory Mist: study the shape for three seconds, then make your cut while it is hidden. PLAY WITH FRIENDS Pass one phone around in Party mode. Two to six players cut the same shapes against a 10- or 15-second clock. Every cut stays secret until the reveal shows everyone’s line, and the best total score wins.

Five daily shapes give you a fresh challenge; replay them to practice after your first scored cut.
