3x3 OLL 28 algorithm
3x3 OLL 28 algorithm: 9 turns, opening with Rw U R'. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 28 belongs to the All Corners Oriented group in OLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL, UBL, UBR. Upper edges with that color facing up: UL, UB.
Execute the algorithm
Rw U R' U' M U R U' R'
The opening is Rw U R'; the final segment is R U' R'. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
