3x3 OLL 2 algorithm
3x3 OLL 2 algorithm: 11 turns, opening with y' R 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 2 belongs to the Dot Case 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: none.
Execute the algorithm
y' R U' R2 D' Rw U Rw' D R2 U R'
The opening is y' R U'; the final segment is R2 U R'. This version contains 11 face, wide, or slice turns and 1 whole-puzzle rotation.
