3x3 ZBLL L 71 algorithm
3x3 ZBLL L 71 algorithm: 15 turns, opening with y' 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 L 71 belongs to the L6 group in ZBLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL, UBR. 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 F L; R: U R L; B: F B U; L: F L R. The letters identify colors by their reference faces.
Execute the algorithm
y' R U R' U R U' R' U R U' R' U R U2 R'
The opening is y' R U; the final segment is R U2 R'. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
