===Speedcubing methods===
A solution commonly used by speedcubers was developed by [[Jessica Fridrich]]. This method is called [[CFOP method|CFOP]] standing for "Cross, F2L, OLL, PLL".  It is similar to the [[Layer by Layer|layer-by-layer]] method but employs the use of a large number of algorithms, especially for orienting and permuting the last layer. The cross is solved first, followed by first layer corners and second layer edges simultaneously, with each corner paired up with a second-layer edge piece, thus completing the first two layers (F2L). This is then followed by [[Orientation (geometry)|orienting]] the last layer, then [[permutation|permuting]] the last layer (OLL and PLL respectively). There are a total of 120 algorithms for Fridrich's method, however they are not all required to use the [[CFOP method|CFOP]] method. Most dedicated cubers will learn as many of these algorithms as possible, and most advanced cubers know all of them. If a cuber knows every algorithm for OLL they may be described as knowing full OLL. It is the same for PLL and F2L.

A now well-known method was developed by [[Lars Petrus]]. In this method, a 2×2×2 section is solved first, followed by a 2×2×3, and then the incorrect edges are solved using a three-move algorithm, which eliminates the need for a possible 32-move algorithm later. The principle behind this is that in layer-by-layer, one must constantly break and fix the completed layer(s); the 2×2×2 and 2×2×3 sections allow three or two layers (respectively) to be turned without ruining progress. One of the advantages of this method is that it tends to give solutions in fewer moves. For this reason, the method is also popular for fewest move competitions.<ref name="larspatrus">{{Cite web |title=Rubik's Cube Solution - Petrus Method |url=https://lar5.com/cube/ |access-date=8 November 2018 |publisher=lar5.com}}</ref>

The Roux Method, developed by [[Gilles Roux]], is similar to the Petrus method in that it relies on block building rather than layers, but derives from corners-first methods. In Roux, a 3×2×1 block is solved, followed by another 3×2×1 on the opposite side. Next, the corners of the top layer are solved. The cube can then be solved using only moves of the U layer and M slice.<ref name="rouxmeth">{{Cite web |title=Introduction |url=http://grrroux.free.fr/method/Intro.html |access-date=20 June 2012 |publisher=Grrroux.free.fr}}</ref>
