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

Explana9on: we'll make a U' move (so when we'll make the r move, the two red pieces will become
adjacent to each other, and not diagonal), then we'll make the r move to pair-up the 2 red center
pieces, and finally we'll make a U move to align them both on the lec.
Solving the remaining 2 pieces: The best way to do it is by posiFoning one red center piece on the
lec side (internal lec) of the cube, and the second on the right side, then making an r/r' move to
pair them up. In the following example, both of the remaining pieces are on the right side (internal
right) of the cube (one is on the top face):

Solu9on: [ F2 r' F r ]
Solu9on: [ r' F' r U ]
Explana9on: First we'll make an F2 move to reposiFon one piece into the lec side (so the next r'
move will not affect it, and it will pair up with the piece currently on top) (The reason we make F2,
and not F', is because that in the next move we want them to pair-up adjacently to each other, and
not diagonally). Then we'll make the r' move to pair-up the pieces. Now we'll make an F move to
align both pieces on the right side of front face. Finally we'll make an r move to solve them into
their final posiFon on the top face, so all 4 red center pieces are completely solved.
*This example above applies to all possible cases, as by doing r/r' & F/B/D/U moves you can
posiFon the 2 remaining center pieces into the same situaFon and solve the same way.
The 4th center block: The fourth center block to solve is the opposite in color to the one we've just
solved,
meaning the orange (again, applies only to original color-scheme cubes, where the orange is
opposite to red).
First we'll flip the cube upside down so the red center will be on the boMom face (yellow & white
sFll on L & R faces). We'll have to bring all the orange center pieces into the top layer. Hopefully
some of them are already there.
We'll use the "elevator" principle to upload the orange pieces into the top, without harming the red
pieces on the boMom. Here is an example to how it's done:
