Hey i have a little bit trouble to solve my 4x4x5 :/
I can solve it when i dont get parity. Because when i use PLL parity of 4x4 the inner center pieces will get messed up like in the picture :O

Is anyone here who can help me :mrgreen:

Have you tried (r2 R2 u2) x3? Either that or something along the lines of that algorithm should work. Unless the other center piece isn't where I think it is. Could you show a picture of the other side?

I think I've worked out what you have to do for most cases. If you put a picture up later I'll try and give you an algorithm. :)

OK, try this: Hold it so on the front face one of the scrambled center pieces is on the right, and perform this: (r2 R2 u2)x2 b2 u2 r2 R2 u2 b2 r2 R2.

Sebuver, how in god's name do you figure out those algorithms!?

You switch the two edges intuitively, then try again try again etc. When you know it by heart you decode :)

I'm a genius. :lol:

Seriously, I worked it out from experience. if you perform (R2 U2)x3 on a 3x3x3, you get the Fish Pattern. If you apply it irregulary on higher order puzzles, then different things happen. For example, it flipped the middle edges around internally which you couldn't see. Then you're left with 4x4x4 parity, in which I used my own algorithm which I made up and use on the 4x4x4. To make sure I was correct, I just used a 5x5x5.

Glad I could help solve the problem Rouricht! :D

My algorithm (white - U, light-blue - F):

(F2 2U2 r2 2U2)*2 - 8 turns.

Your algorithm is elegant.
