3x3 ZBLL T 16 algorithm
3x3 ZBLL T 16 algorithm: 15 turns, opening with y2 F 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 T 16 belongs to the T2 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 R; R: B R U; B: B L R; L: U F L. The letters identify colors by their reference faces.

y2 F R U R' U' R' F' U2 R U R U' R2 U2 R
The opening is y2 F R; the final segment is R2 U2 R. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
