3x3 ZBLL T 25 algorithm
3x3 ZBLL T 25 algorithm: 10 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 T 25 belongs to the T3 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 B B; R: L L U; B: F R F; L: U F R. The letters identify colors by their reference faces.

R' U R U2 L' R' U R U' L
The opening is R' U R; the final segment is R U' L. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
