3x3 OLL 25 algorithm
3x3 OLL 25 algorithm: 9 turns, opening with R U2 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 25 belongs to the OCLL 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: UF, UL, UB, UR.
Execute the algorithm
R U2 R D R' U2 R D' R2
The opening is R U2 R; the final segment is R D' R2. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
