Rubik's Cube: Orientation of the Last Layer

About OLL

There are in total 57 OLL (Orientation of the Last Layer) cases in the CFOP method. Actually it’s not necessary to learn all of them to solve a cube. Many people use only 10 of them, in a two-step manenr, which is often called double-O in the “CFOOP” strategy. Based on my personal experience, you don’t have to remembere all of them to get an average of 17s.

Here I show a chart of all the 57 OLL algorithms. They are organized in a two-dimensional way: rows/columns represent different cases of edges/corners, respectively. Yellow is the color of the upper face.
