Rubiks Revenge - Solving The Centres

Updated on May 23, 2014

We begin the reduction method in order to solve the 4x4x4 Rubiks Revenge Cube.

In the 3x3x3 reduction method, the 4x4x4 is initially partially solved so it can be treated and solved as a Standard Rubik Cube.

The goal of the first step is to solve the 4 centre pieces on each face of the cube (any cubie with only one color, there are four cubies on each of the six faces).

Since there is no reference centre, this will require find out and memorize the color scheme of the 4x4x4 Rubiks Cube.

Warning:

If you haven’t read the first part, please read it before continuing.

The first step in solving the Rubiks Revenge Cube is to solve the Centres (2x2 block), in order to have a point of reference for solving the rest of the cube.

Step 1, Solving The Centres

You begin solving two opposite Centres.

The first step is to make two rows (2x1 block) of each color.

Choose two opposite colors (let's take White and Yellow, they can be any two opposite colors).

 
.

I] First White Row

If the cube has a White row already solved, place it in the u Face and go to II]

Look for two White Centre Pieces and locate one piece in the Front Face and another in the Upper Face. There are two possible states:

r' - F2
r' - F2
l - F2
l - F2

If the pieces are in diagonal:

r - U - r' - F2
r - U - r' - F2

II] First Yellow Centre

Place the solved White row in the Back Face (u2 move).

If the cube has a Yellow row already solved, place it in the u Face (without disassembling the solved White row) and go to III]

Solve the opposite (Yellow) row. There are two possible states:

a)

Look for two Yellow Centre Pieces and locate one piece in the Right Face and another in the Upper Face.

f - d' - F2
f - d' - F2

Look for two Yellow Centre Pieces on the Upper, Left, Right, Down Faces (U-L-R-D section) and locate one piece in the Right Face and another in the Upper Face:

B - b' - d'
B - b' - d'

If the Centre Piece is located in the Front or Back Face, move the d Face without placing another piece in the Front or Back Face.

b)

Three Centre Pieces in the Front Face and one in the U-L-R-D section:

B - r - U' - r' - B'
B - r - U' - r' - B'

III] Finishing the White Centre

Place the solved White row in the Front Face. Look for two White Centre Pieces, there are three possible states:

  • a) Already solved in U-L-R-D section.

  • b) Not solved in U-L-R-D section.

  • c) One piece in U-L-R-D section and another in Front Face.

a) Already Solved In U-L-R-D Section

 .

a1)

d - R2 - d'
d - R2 - d'

a2)

R2 - d - R2 - d'
R2 - d - R2 - d'

a3)

U - b' - R' - d - R2 - d'
U - b' - R' - d - R2 - d'

a4)

d' - b - R' - d - R2 - d'
d' - b - R' - d - R2 - d'

b) Not Solved In U-L-R-D Section

 .

F' - f - R2 - d - R2 - d'
F' - f - R2 - d - R2 - d'

c) One Piece In U-L-R-D Section And Another In Front Face

. 

c1)

F' - d' - F - d
F' - d' - F - d

c2)

R - d - R' - d'
R - d - R' - d'

IV] Concluding The Centres

The first two Centres are solved. For the next step White and Yellow become the top and bottom faces (let's take White Down Face, Yellow Upper Face).

For the four remaining Centres, there are three possible states:

  • a) Resolved, in the correct position.

  • b) Resolved, not in the correct position.

  • c) Not resolved.

a) In The Correct Position

If the Centres are resolved in the correct position, go to Pairing Up The Edges

b) Not In The Correct Position

If the Centres are resolved but not in the correct position, you should exchange the faces:

d' - F2 - d2 - R2 - d'
d' - F2 - d2 - R2 - d'

c) Not Resolved

Solve two opposite Centres, by making two rows (2x1 block) of each color (let's take Red and Orange).

If the cube has a Red row already solved, place it in the u Face and go to next step.

Look for two Red Centre Pieces and locate one piece in the Front Face and another in the Right Face as is shown.

d' - F - d
d' - F - d

Place the solved Red row in the Back Face (u2 move). Solve the opposite (Orange) row.

If the cube has an Orange row already solved, place it in the u Face (without disassembling the solved Red row) and go to next step.

Look for two Orange Centre Pieces and locate one piece in the Front Face and another in the Right Face as is shown.

F - d - R - d' - F2
F - d - R - d' - F2

Moving the d layer and the outer layers only, if the cube has an Orange row already solved, place it in the d face and go to next step.

Arrange the cube as shown (without disassembling the solved Red row)

d - R' - d'
d - R' - d'

In order to finish the Red Centre, arrange the cube as shown in one of the six possible states:

a)

d' - F - d
d' - F - d

b)

d - R' - d'
d - R' - d'

c)

d' - F2 - d
d' - F2 - d

d)

d' - F - d - F2 - d' - F - d
d' - F - d - F2 - d' - F - d

e)

d - R' - d' - R2 - d - R' - d'
d - R' - d' - R2 - d - R' - d'

If the Red Centre Pieces are at opposite layers, place the Red row in the Right Face and place both Centre Pieces in the u-r intersection:

f)

d - B' - d' - R - d' - F - d
d - B' - d' - R - d' - F - d

The two remaining Centres are solved easily in few movements. (If you need help, see all the possible cases here).

Next step, Pairing Up The Edges.
