x y z: whole cube rotation

Adding [T]: turning two layers of the corresponding side

Adding [M]: turning the internal layer of the corresponding side

Adding [‘]: 90 degree turn counter clockwise

Adding [2]: 180 degree turn clockwise

Adding [‘2]: 180 degree turn counter clockwise

In this tutorial we will introduce the ‘Reduction method’ which will require us to first solve the center pieces and turn the edge pieces to form an equivalent to the 3x3x3 cube. Then we will be able quickly solve the cube using the methods for solving the 3x3x3 cube.

Solve the center
pieces of all 6 sides

Pair the edge pieces

Apply 3x3x3 methods
&deal with parities

Done

1

Solve the center pieces

by aligning the 4 center pieces of each colour and positioning them in the orders
Solve the center pieces of the yellow face.
Solve the center pieces of the white face.
Solve the center pieces of the remaing faces one by one.

For big cubes with even number of layers, the center pieces are not fixed on certain sides You need to memorize the relative positions of the different colours. In the case of GAN460 this is top-yellow, down-white, left-orange, rlght-red, fronC-blue, back-green.

Turn the edge pieces

to pair them up
Start with any pair of edge pieces (we take red/blue edges as example below). Take the right side edge slots (marked in grey below) as working slots. Use algorithm 3 to line up the edge pieces.
Flip the cube when the 4 edges on the top side are all paired up. Repeat step 1 for the unsolved edges (now flipped to top side) until the remaining 4 edges are all paired up.

If the last 2 edge pairs can not be solved, apply algorithm 4.

Solve the cube like the 3x3x3 cube, and deal with parities.

Now your 4x4x4 cube should look like a 3x3x3 cube. Use the 3x3x3 methods to solve it until you encounter a parity case.

In case of parity situations, use the algorithms below

Two scenarios as shown below might happen when making the
cross on the top side. Use algorithm 5 to handle it

Algorithm5 TR U2 x TR U2 TR U2′ TR’ U2 TL U2 TR’ U2′ TR U2 TR’ U2′ TR

When solving the top face, if you entcounter the scenario can
not be solved, apply algorithm 6 once where 2 opposite edges to solve it.

Algorithm6 MR2 U2 MR2 TU2 MR2 MU2

In the emergence of any of the 3 scenarios shown on the right, apply algorithm 6 once in any direction, then continue to solve the cube using 3x3x3 methods.
