3x3 ZBLL U 71 algorithm
3x3 ZBLL U 71 algorithm: 17 turns, opening with R 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 U 71 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: L R L; R: F B R; B: U L U; L: R F B. The letters identify colors by their reference faces.
Execute the algorithm
R U R' U' R U' R U2 R2 U' R U R' U' R2 U' R2
The opening is R U R'; the final segment is R2 U' R2. This version contains 17 face, wide, or slice turns and no whole-puzzle rotations.
