3x3 ZBLL H 18 algorithm
3x3 ZBLL H 18 algorithm: 18 turns, opening with y2 R' U'. Case recognition, the complete sequence, and practical execution notes.
Solve the entire last layer in one sequence when its edges are already oriented.
ZBLL H 18 belongs to the H2 group in ZBLL.
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: UF, UL, UB, UR. Reading each side’s top row left to right when facing that side gives F: L R B; R: U B U; B: F L L; L: U F U. The letters identify colors by their reference faces.
Execute the algorithm
y2 R' U' R U' R' U F' R U R' U' R' F R2 U' R' U R
The opening is y2 R' U'; the final segment is R' U R. This version contains 18 face, wide, or slice turns and 1 whole-puzzle rotation.
