@brunogirin @pikesley @babe Never did solve that one.
Good lord, you have a problem. Allow me to help.
@pikesley @babe @ayukawa FWIW this is "just" a rubik's cube that you have to care about the orientation of the face-centres https://rubiks.fandom.com/wiki/Axis_Cube
I still curse the friend who gave me mine scrambled because unsolved it itches
@SamLR presuming you can solve it (which is head-scratchy even if you're adept with a regular 3x3) then it's just this https://www.youtube.com/watch?v=kbj9xI_-iiI
@ayukawa @SamLR @babe Lookup "superflip" BUT instead of rolling the centre slice UP, roll it DOWN each time. Try it with a 3x3 first until it makes sense. Then to get this layering, start at the outermost layer and work your way in.
It's entirely possible none of this makes sense, not sure I've ever attempted to explain it before.
