3x3 ZBLL U 72 algorithm
3x3 ZBLL U 72 algorithm: 14 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 U 72 belongs to the U6 group in ZBLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. 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 F F; R: R R B; B: U B U; L: B L L. The letters identify colors by their reference faces.
Execute the algorithm
y R U2 R' U' R U' R' L' U2 L U L' U L
The opening is y R U2; the final segment is L' U L. This version contains 14 face, wide, or slice turns and 1 whole-puzzle rotation.
