Ua-perm
Edges only
Ua-perm is a PLL case on the 3x3 (Edges only, easy). Algorithm: R U R' U R' U' R2 U' R' U R' U R. Below are 3 variants with a 3D animation and a scramble to practise.
My status:don’t know
How the status is counted
Training counts the status. A case added to training gets “learning”, and “known” after 5× “correct” in a row with the timer and without hints, when the average time is within the category threshold (Settings). 2× “wrong” in the last 3 attempts or much slower times drop it back to “learning”. Daily tasks don’t change the status.
How to recognize
A bar in front. The edge on the left is the opposite colour of the side, the one on the right is not.
