CFOP method

The CFOP method (Cross – F2L – OLL – PLL), also known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3 Rubik's Cube and is one of the fastest methods. This method was first developed in the early 1980s, combining innovations by a number of speed cubers. Jessica Fridrich, a Czech speed cuber and the namesake of the method, is generally credited for popularizing it by publishing it online in 1997.

The method works by first solving a cross typically on the bottom, continuing to solve the first two layers together (F2L), orienting the last layer (OLL), and finally permuting the last layer (PLL). There are 78 algorithms in total to learn for OLL and PLL but there are other algorithm sets like ZBLL and COLL that can be learned as an extension to CFOP to improve solving efficiency.
