3x3 ZBLL L 72 algorithm
3x3 ZBLL L 72 algorithm: 13 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 L 72 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: L L F; R: U F F; B: R R U; L: R B B. The letters identify colors by their reference faces.
Execute the algorithm
R U' R' L' U2 L U L' U L R U2 R'
The opening is R U' R'; the final segment is R U2 R'. This version contains 13 face, wide, or slice turns and no whole-puzzle rotations.
