3x3 ZBLL H 28 algorithm
3x3 ZBLL H 28 algorithm: 13 turns, opening with x' U' R. 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 28 belongs to the H3 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: B B B; R: U L U; B: F F F; L: U R U. The letters identify colors by their reference faces.
Execute the algorithm
x' U' R U' R' U R' F2 R U' R U R' U x
The opening is x' U' R; the final segment is R' U x. This version contains 13 face, wide, or slice turns and 2 whole-puzzle rotations.
