3x3 OLL 51 algorithm
3x3 OLL 51 algorithm: 10 turns, opening with y2 F 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 51 belongs to the Line Shapes 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: UL, UR.
Execute the algorithm
y2 F U R U' R' U R U' R' F'
The opening is y2 F U; the final segment is U' R' F'. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
