I just upgraded from my original Aosu to an Aosu GTS M and it's massively better. Not sure about the Aosu GTS M vs. Wuque M comparison, I just got the one that was on sale :)

If you don't want to learn Yau, you can do freeslice and learn to solve multiple edges at once, look up 323 edge pairing. Or you can do Meyer, which is basically the Roux version of Yau (it's pretty similar).

So while I was waiting for a competition I bought a 4x4, but since I didn't have any WiFi I couldn't watch any videos on how to solve it. I was able to get up to PLL, but now I'm stuck.

So I am able to get up to this point on my own.


Anybody know how I can swap those?

The exact case as in the picture is indeed impossible, but what's possible are cases like these:



For these, the solution is as 1001010101001 mentioned: do some setup moves to bring the two pieces you want to swap to the UFr and UBr positions, do that alg, then undo the setup moves.

That case shouldn’t be possible. My guess is some stickers may have gotten swapped
R U R’ U’ — setup
(Take r as a slice turn)
l’ U2 l U2 l U2 r’ U2 l U2 l’ U2 F2 l2 F2 r

U R U’ R’

Edit :If you don’t have wifi, how did you post this?
What I was trying to say was that I didn't have WiFi when I first bought the cube and tried to solve it.

For pll has anyone compiled a list of algs for the remaining cases with parity?
Thanks in advance
If you mean for PLL parity, I put quite a few algorithms for most of the 22 PLL Parity cases at the beginning of the 4x4x4 parity algorithms Wiki page. I have included all (or at least most) of the original algorithms found for these cases back at the beginning of the century.

I am aware that there have been several videos of PLL parity tutorials featuring new (and possibly faster) algorithms for each of the cases, but I lost track of them. If someone does his or her research and figures out which algorithms for PLL parity cases which are already not in the Wiki and lists them here, I will add them to the Wiki.

Is there a nice way to solve this pll parity case?
Set Up: (V Perm) U2 R U R' U' (PLL Parity) U' R U' R'
Just do PLL parity + E perm.

Alternatively, Uw2 Rw2 U2 Rw2 R' D R' U' R (U2 D') R' D' R U2 R' (U' D) Rw2 Uw2, or one of the algs in the wiki page linked in the post directly above yours.

i ever accidentally get this condition, i did oll algorithm but i realised this condition so i reversed oll algorithm before oll algorithm is done and i did oll parity 2 times

if you get this condition :




do oll parity algoritm 2 times with this algorithm

(Rr)2 B2 U2 (Ll) U2 (Rr)' U2 (Rr) U2 F2 (Rr) F2 (Ll)' B2 (Rr)2

and your 4x4 will be solved
