What OLL does
OLL orients the last-layer pieces so the U face becomes one color. Their positions may still be wrong, and PLL solves that next.
Two-look OLL and full OLL
Two-look OLL first orients edges with EOLL, then corners with OCLL. It is a reliable start with fewer algorithms. Full OLL handles all 57 shapes in one step, trading more recognition and memorization for speed.
Recognition basics
- Start from the U face: identify the dot, line, L, or cross.
- Once the edges are oriented, read the corner shape: Sune, Antisune, T, Pi and the rest.
- Check the AUF, then start each algorithm from the same reference.
Where it fits in CFOP
OLL follows Cross and four F2L pairs, then hands off to PLL. Use CFOP Solve to walk through a full solve stage by stage.
