3x3 OLL 18 algorithm
3x3 OLL 18 algorithm: 12 turns, opening with y R U2. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer after completing F2L; permutation is handled in the next stage.
OLL 18 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 R U2 R2 F R F' U2 M' U R U' Rw'
The opening is y R U2; the final segment is R U' Rw'. This version contains 12 face, wide, or slice turns and 1 whole-puzzle rotation.
