How to Solve a Rubik’s Cube in 20 Moves, often abbreviated as CFOP (Cross, F2L, OLL, PLL), is a popular method for solving the iconic Rubik’s Cube puzzle. Invented by Jessica Fridrich in 1997, CFOP is widely recognized as one of the most efficient and beginner-friendly methods, allowing solvers to achieve sub-20-second solve times with practice.
The CFOP method is divided into four main steps:
- Cross: Solve the white cross on the bottom face.
- F2L (First Two Layers): Pair up and insert the remaining edge and corner pieces of the first two layers.
- OLL (Orientation of Last Layer): Orient the last layer edges correctly.
- PLL (Permutation of Last Layer): Permute the last layer corners and edges to solve the cube.
Each step involves a series of specific algorithms and techniques, which can be learned and memorized with practice. The 20-move sequence refers to the minimum number of moves required to solve the cube using the CFOP method, although in practice, most solvers require a few more moves to complete the solution.
