3x3 ZBLL T 38 algorithm
3x3 ZBLL T 38 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 T 38 belongs to the T4 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 B B; R: L F U; B: F R B; L: U L L. The letters identify colors by their reference faces.

The opening is y' R U; the final segment is R U' R'. This version contains 17 face, wide, or slice turns and 1 whole-puzzle rotation.
