colors, and then restore it to its original state of having one color per face by turning each face in sequence to reorient/reposition the edge and corner pieces adjacent to that face's center piece. Solutions Regardless of color variant, the most common solution strategy shares qualities with common methods for solving a Rubik's Cube. The solution begins with one face (most often white), where the solver will reconstruct the "star" formed by the edge pieces adjacent to that face, each one properly paired with the neighboring center color (analogous to the "white cross" of the beginner and CFOP methods for a Rubik's Cube). Once this is done, the five white corner pieces are maneuvered into place, commonly paired with the appropriate edge piece on the opposing side of each corner from the starting face. The star, first five corners and first five edges are known as the "first two layers", similar to those of a 3x3 cube. From here, the solver will typically proceed to the "second two layers", which involves a similar process of joining and positioning corner and edge pieces around the equator of the puzzle, and then the corners and edges in the hemisphere opposite the starting face. This is all typically done "intuitively", turning faces of the puzzle based on where the solver wishes the pieces to move, with the result of each move being predictable given some experience manipulating the puzzle. This leaves the solver with the "last face", most commonly grey (opposite the white starting face), which will require a series of more complicated move sequences to orient (flip/rotate) and permute (rearrange) the pieces of the last layer in predefined ways without disturbing the solved lower layers. These "algorithms" are similar to those used on a Rubik's Cube and thus familiar to those experienced in solving one, with the obvious allowance made for the extra side of each face (and thus the extra turn possible as part of a full revolution of the face). The "beginner" method requires only four or five algorithms of between three and six moves each to be memorized, which will be used to orient and then permute the last layer's edge pieces to form the last layer star, followed by orienting and permuting last layer corners. More complicated algorithm sets require memorization of a wider variety of distinct sequences of longer length, which nevertheless are more efficient solutions for
