This OLL system is used to orient all the pieces on the last layer as described in the Jessica Fridrich method, you do not need to know all 57 OLLs to use 2-look OLL, rather the system is divided up. By first orienting the edges (three cases), then orienting the corners (7 cases), orientation of all pieces on the last layer is completed.
- Step 1: Orientation of Edges. This requires the use of one of 3 algorithms:
- Step 2: Orientation of Corners. (AKA OCLL) Requires the use of 7 algorithms (6 excluding mirrors), to solve the following OLL cases:
