3x3 ZBLL H 3 algorithm
3x3 ZBLL H 3 algorithm: 18 turns, opening with y' R U2. 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 3 belongs to the H1 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: F R F; R: U F U; B: R B L; L: U L U. The letters identify colors by their reference faces.
Execute the algorithm
y' R U2 R' U' R U R' U2 R' F R2 U' R' U' R U R' F'
The opening is y' R U2; the final segment is U R' F'. This version contains 18 face, wide, or slice turns and 1 whole-puzzle rotation.
