The Square-1 (or Cube 21) is a cubic twisty puzzle, with irregular cubies. It has only three axes of rotation - the top and bottom faces, and the entire right half of the puzzle. The puzzle consists of two halves, each with corner and edge pieces indistinguishable to the core. The top and bottom layers consist of triangular edge pieces and quadrilateral corner pieces, and the middle layer consists of two trapezoidal pieces. This puzzle does not have fixed center, and when scrambled, shifts to a random shape. The object is to return it to its cubic state as well as to make each side one solid color.
The Square-1 is a interesting puzzle - the concepts of other puzzles can be applied to it, however, it is unique in that corners and edges are indistinguishable to the puzzle's inner mechanism - meaning corners can be swapped with edges and therefore the puzzle can change shape. The puzzle is much easier to work with when it is in the shape of a cube so generally the first step is to somehow (there are several methods) get the pieces arranged so that the puzzle is cubic. Then, the pieces are separated into their correct layers, and permuted. Note that there is no possible incorrect orientation for pieces, since the middle layer can only rotate through 180 degrees at a time (many talks about separation as "orientation").
