Rb-perm
Adjacent swap
Rb-perm is a PLL case on the One-handed 3x3 (Adjacent swap, medium). Algorithm: R' U2' R' D' R U' R' D R U R U' R' U' R. Below are 2 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
One bar next to the left side of the headlights. Hold the headlights in front.
