Perfect Slices is about cutting things cleanly. Objects — fruit, vegetables, cakes, occasionally more absurd things — rotate in front of you, and you throw knives to slice them. The score depends on how evenly you cut: hit the exact centre and you get a perfect slice bonus.
It's a physics-and-timing game rather than a reflex one, and it belongs to the enormously popular 'satisfying' genre — the appeal is as much the clean cut and the sound as the score.
Throw when the object's centre line is facing you, so the knife passes exactly through the middle. Perfect slices award a bonus and chain into a multiplier.
Levels give you a set number of knives rather than a clock, so the pressure is on accuracy rather than speed.
