3x3 ZBLL Pi 10 algorithm
3x3 ZBLL Pi 10 algorithm: 15 turns, opening with y' F 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 Pi 10 belongs to the Pi 1 group in ZBLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. 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: R R U; R: L F L; B: U B R; L: U L U. The letters identify colors by their reference faces.
Execute the algorithm
y' F U' R U' R' U R U R' U2 R U2 R' U F'
The opening is y' F U'; the final segment is R' U F'. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
