Slice It! is a game that tasks players with cutting up different shapes into pieces of equal size. For each puzzle, players are told how many pieces they must slice the shape into, and are given a set amount of slices to achieve it. They cannot slice any more or less. It starts off simple enough but as the levels continue, the puzzles become increasingly hard, and players will eventually need to use their maths skills to adjust their slices.

Before beginning each puzzle, players are told how many slices they need to create to complete the stage. In order to cut up the shapes equally into the set amount of pieces, the player has to often plan ahead to make sure they do not fall short of the required slices. Some shapes are irregular and it is not easy or obvious on where to make the cuts.
