3x3 OLL 37 algorithm
3x3 OLL 37 algorithm: 8 turns, opening with F R' F'. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 37 belongs to the Fish 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: UL, UB.
Execute the algorithm
F R' F' R U R U' R'
The opening is F R' F'; the final segment is R U' R'. This version contains 8 face, wide, or slice turns and no whole-puzzle rotations.
