3x3 OLL 31 algorithm
3x3 OLL 31 algorithm: 9 turns, opening with R' U' 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 31 belongs to the P 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, UBR. Upper edges with that color facing up: UB, UR.
Execute the algorithm
R' U' F U R U' R' F' R
The opening is R' U' F; the final segment is R' F' R. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
