Z-perm
Edges only
Z-perm is a PLL case on the 3x3 (Edges only, medium). Algorithm: M' U' M2 U' M2 U' M' U2 M2. 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
Like H-perm, but without opposite colours: two sides form a checkerboard. Hold the checkerboard on the right.
