Twisty shapes, also known as 'twisty puzzles' or 'puzzle cubes, ' are 3-dimensional puzzles that have been around since the 1970s. They consist of a cube made up of several smaller cubes, each of which can be twisted and turned in different directions. The goal is to rearrange the pieces so that all of the sides match up. The term 'ESSES' is an acronym for the six sides of the cube: Edge, Side, Edge, Side, Edge, Side.
