2-Look OLL

This OLL system is used to orient all the pieces on the last layer as described in the CFOP method, you do not need to know all 57 OLLs to use 2-look OLL (commonly abbreviated as 2L-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 (EOLL-IgnoreC) . This requires the use of one of 3 algorithms:
  1. to flip adjacent edges
  2. to flip opposite edges
  3. to flip all four edges
• Step 2: Orientation of Corners (OCLL) . Requires the use of 7 algorithms (6 excluding mirrors), to solve the following OLL cases:
  1. T
  2. Bowtie
  3. Headlights
  4. Sune
  5. Anti-Sune
  6. H
  7. Pi

Orientation of Corners (CO Only) and then Orientation of Edges (AKA OELL, AKAOLL-E or OLL-ACO) is also 2L-OLL, but this is less used.
