3x3 ZBLL U 34 algorithm
3x3 ZBLL U 34 algorithm: 17 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 U 34 belongs to the U3 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: B R B; R: L F R; B: U B U; L: L L R. The letters identify colors by their reference faces.
Execute the algorithm
y R U R' U R U2 R' U R U2 R D R' U2 R D' R2
The opening is y R U; the final segment is R D' R2. This version contains 17 face, wide, or slice turns and 1 whole-puzzle rotation.
