3x3 OLL 15 algorithm
3x3 OLL 15 algorithm: 10 turns, opening with Rw' U' 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 15 belongs to the Knight Move 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. Upper edges with that color facing up: UL, UR.
Execute the algorithm
Rw' U' Rw R' U' R U Rw' U Rw
The opening is Rw' U' Rw; the final segment is Rw' U Rw. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
