3x3 OLL 19 algorithm
3x3 OLL 19 algorithm: 10 turns, opening with y S' 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 19 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: UBL, UBR. Upper edges with that color facing up: none.
Execute the algorithm
y S' R U R' S U' R' F R F'
The opening is y S' R; the final segment is F R F'. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
