3x3 CMLL Sune Down Slash algorithm
3x3 CMLL Sune Down Slash algorithm: 8 turns, opening with U Rw U'. Case recognition, the complete sequence, and practical execution notes.
Solve the four upper corners in Roux after building both side blocks; the remaining edges are solved later.
Sune Down Slash belongs to the Sune group in CMLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR. Upper edges with that color facing up: UL. Reading each side’s upper corner stickers left to right when facing that side gives F: R F; R: R U; B: B U; L: L U. The letters identify colors by their reference faces.
Execute the algorithm
U Rw U' Rw' F R' F' R
The opening is U Rw U'; the final segment is R' F' R. This version contains 8 face, wide, or slice turns and no whole-puzzle rotations.
