Basic layerbylayer methods were among the first to arise during the
early 1980s cube craze.

(April 2017) (Learn how and when to remove this template message) First Two Layers solved Orientation of the Last Layer complete The method consists of 4 steps: The Cross  This first stage involves solving the four edge pieces in one outer layer of the puzzle, centring around a commonly coloured centre piece. First Two Layers (F2L)  In F2L, corner and edge pieces are paired up and later moved to their correct location. There are 42 standard cases for each corneredge pair including the case where it is already solved. It can also be done intuitively. Orientation of the Last Layer (OLL)  This stage involves manipulating the top layer so that all the pieces therein have the same colour on top, at the expense of incorrect colours on other sides. This stage involves a total of 57 algorithms. A simpler version, called "twolook OLL" orients edges and corners separately. It uses nine algorithms, two for edge orientation and seven for corner orientation. Permutation of the Last Layer (PLL)  The final stage involves moving the pieces of the top layer while preserving their orientation. There are a total of 21 algorithms for this stage. They are distinguished by letter names, usually based on what they look like with arrows representing what pieces are swapped around (e.g. A permutation, F permutation, T permutation, etc.). "Twolook" PLL solves the corners and edges separately. It uses six algorithms, two for corner permutation and four for edge permutation. Competition use[edit]
