CFOP, which stands for Cross, F2L (First Two Layers), OLL (Orientation of the Last Layer), and PLL (Permutation of the Last Layer), is a popular method for solving the Rubik's Cube. It breaks down the solving process into four main steps, making it easier for beginners to learn and master the cube. The CFOP method starts with solving the cross on one face, followed by pairing and inserting the first two layers. Next, the last layer's pieces are oriented, and finally, they are permuted to their correct positions. This systematic approach helps cubers improve their speed and efficiency.
