E-perm
Corners only
E-perm is a PLL case on the 3x3 (Corners only, trudny). Algorithm: x' R U' R' D R U R' D' R U R' D R U' R' D' x. 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
No blocks, bars or headlights. The edges are in their places, so it’s not H-perm.
