How to Solve a 4x4 Cube- the Rubik's Revenge

Solu9on: [ r' F2 r ]
following moves:
Example: uploading 2 white center pieces from the F face (same for all faces).
Explana9on: since we have to preserve the center pieces at the boMom, just doing an r / l move is
not enough. Therefore, we make an r' move and take down the non-white center pieces on top into
the F face, then switch them with the 2 white pieces, by doing F2. (There are 2 yellow pieces on the
back face at the moment, which will go back into their solved posiFon in the next move). Now we'll
finally reverse the r' move by doing an r move. The white pieces are now correctly posiFoned on
the top face, and all yellow pieces on the boMom remained unharmed.
This is an important idea in understanding the 4x4 soluFon. It's just like an "elevator" move, we
bring down the "elevator" toward the pieces we want to reposiFon, "upload" the pieces into the
"elevator", and elevaFng them upwards into the solved posiFon. That way we are able to posiFon
pieces while preserving already solved pieces.
When 3 center pieces are on top:
Same idea is implemented here: We'll use the elevator idea as well. In
fact the algorithm is almost similar-
Solu9on: [ r' F r ]
The only difference is that we have to make only single F turn, because one white piece was already
"inside" the elevator.
If the 3 white pieces on top, or the piece on the front face, are posiFoned differently than in the
example, all you have to do is just some U / F turns to adjust them like in the image and solve.

How to Solve a 4x4 Cube- The Rubik's Revenge

Example: forming 2 adjacent red pieces.
Solu9on: [ U' r U ]
The 3rd center block: we can choose any of the remaining four colors to be the third block to solve.
In this guide I chose red.
It is best to rotate (flip) the cube so the solved center blocks (yellow & white) will be on the R & L
faces.
Make some r/r' & U/F/B/D moves to form 2 adjacent red pieces. Rotate
(flip) the cube so they will appear on the top face (yellow & white sFll on R & L faces). Then make
some U turns, if needed, in order to align the 2 red center pieces on the lec side of the top face(see
image for lec/right internal side explanaFons) (can be the right side as well, I'm personally used to
lec since I'm right-handed), like in the example below (right image):
