PLL Ub — Ub Permutation

Edges Only.

Recognition — what PLL Ub looks like
Guided walkthrough — PLL Ub, trigger by trigger

Algorithm

7 moves. Execute with the cube already oriented (top face one colour) and the last layer on top.

Setup / recognition

Apply this scramble to a solved cube to reach the PLL Ub case so you can practise it on demand:

Perm family: U. You recognise it by the edges only — read the headlights, bars and blocks on the side stickers before turning.

About this case

PLL Ub (Ub Permutation) is a PLL case — the permutation step of CFOP. Edges Only. It is performed after OLL has oriented the top face; once this algorithm cycles the pieces into place, the cube is solved.
