3x3 OLL 49 algorithm
3x3 OLL 49 algorithm: 9 turns, opening with y2 Rw U'. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 49 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, UL.
Execute the algorithm
y2 Rw U' Rw2 U Rw2 U Rw2 U' Rw
The opening is y2 Rw U'; the final segment is Rw2 U' Rw. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
