3x3 OLL 39 algorithm
3x3 OLL 39 algorithm: 9 turns, opening with y' Fw' Rw. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 39 belongs to the Lightning Shapes group in OLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UBL. Upper edges with that color facing up: UF, UB.
Execute the algorithm
y' Fw' Rw U Rw' U' Rw' F Rw S
The opening is y' Fw' Rw; the final segment is F Rw S. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
