First step of CFOP : Cross


Cross
The first step is to make a cross on the bottom face by solving four edge pieces that share one color . The cross is the step with the least amount of structure, so it takes a number of thinking and creativity to come up with a good solution. Hold your cube on your hands with the white centre facing down to improve your solution time. With numerous practice you won't need to see the white cross because you'll recognize what's going on down there according to the color scheme of your puzzle, your movements and what you notice on the top. This way you don't have to turn your cube around, saving a lot of time. A few speedcubers decide on fixing the move on the left facet but if you choose to make it on the lowest you may have a pleasant lookahead and is greater appropriate for finger hints.

Second step of CFOP : F2L


F2L
The first layers (F2L) of the Rubik's cube are solved simultaneously instead of individually to lessen the solving time significantly. Within the 2nd step of the CFOP technique, we solve the 4 white corner pieces and the edges attached to them. To be efficient try not to turn your cube around while solving and look ahead as much as possible. Be familiar with the algorithms so you can do them with your eyes closed.

Third step of CFOP : OLL


OLL or Orientation of the Last Layer is the third step of the CFOP method, which aims to orient (same color facing up) the top layer of the 3x3. This step is fully algorithmic, and consists of 57 cases. OLL has the most algorithms in the CFOP method

Fourth Step of CFOP : PLL


PLL is the acronym for Permutation of the last Layer. Permutation of the last Layer is the remaining step of many speedsolving methods. on this step, the portions on the pinnacle layer have already been oriented (OLL) in order that the top face has all the same color, and they are able to now be moved into their solved positions. There are 21 PLLs (13 if you count mirrors and inverses as being the same) and each one is named after a letter.
