3x3 OLL 50 algorithm
3x3 OLL 50 algorithm: 9 turns, opening with Rw' U Rw2. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 50 belongs to the L Shapes group in OLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Upper edges with that color facing up: UF, UR.
Execute the algorithm
Rw' U Rw2 U' Rw2 U' Rw2 U Rw'
The opening is Rw' U Rw2; the final segment is Rw2 U Rw'. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
