Concluding with this series of tutorials, we will see now How To Solve A 4x4x4 Rubiks Cube.

The main purpose of the series, is that you learn in a much more effective way how to solve the Rubik's cubes.

We have seen that the resolution of the Junior Cube it's a subset of the steps for the resolution of Standard Cube.

We will see now that in the case of 4x4x4 Rubik's Cube (and bigger cubes), the method of resolution of the Standard Cube is the base of resolution of more complex cubes.

A way to solve more complex Rubik's Cubes is accomplished through using what is commonly called the 3x3x3 reduction method.

In this method it is necessary that you know how to solve the Standard Cube. If you need to learn how to solve the Standard Cube, please read 'How To Solve A 3x3x3 Rubiks Cube'.

Note:

For simplicity this tutorial is divided in four pages, in this first page terms are defined and the method is described.

In order to understand How To Solve A 4x4x4 Rubiks Cube, you need to be familiar with the notation. If you don't know it, please read 'How to solve a Rubiks Cube' before continuing.

For the purposes of the following tutorial, a series of colors will be chosen for the faces, you can choose others.

• Corner ..- a physical corner piece. A corner piece has three sides. There are eight corners.
• Edge .....- a physical edge piece. An edge piece has two sides. There are twenty four edges.
• Centre ...- a physical centre piece. An centre piece has one side. There are twenty four centres.
• Face .....- a side of the cube. There are six external faces and six internal faces.

A 4x4x4 Rubiks Cube has internal faces, they are named with a lower case letter.

• Internal Upper Face - u

• Internal Down Face  - d

• Internal Left Face  - l

• Internal Right Face - r

• Internal Front Face - f

• Internal Back Face  - b

In a 4x4x4 Rubiks Cube, the internal faces can turn. To facilitate the turn (and the notation) of an internal face, this is rotated together with the outer face.

See the difference in the following examples of a clockwise turn of the External and the Internal Upper Face (also note the double arrow, which denotes to turn two faces).

The algorithm is divided in three steps.

The first step in the solution is to solve the 4 Centre Pieces on each face of the cube.

The next step is to Pair up the 24 Edges into 12 distinct Double Edge Pairs (Dedges)

When you have solved the Centres and Paired up the Edges, you should see your 4x4x4 Rubik Cube like a 3x3x3 Rubik Cube.

You can finish off the cube in the same way as a 3x3x3.

The 4x4x4 Rubiks Cube is an even cube and has no fixed Centre pieces to refer to.

There is no quick way to determine which color goes where in relation to the others. It is helpful to have a color scheme memorised:

Standard Color Scheme

• Yellow opposite White
• Blue opposite Green
• Red opposite Orange

If your cube is scrambled (or it doesn't have the standard color scheme), there is an easy way to determine the scheme.

Simply solve the corners of your 4x4x4 (assuming that you can solve the Corners of a 3x3x3).

Once you've figured out your colour scheme, memorize it or write it down.

At some point in your 4x4x4 Rubik Cube solving it is possible that you make a mistake with your Centres, such as transposing two Opposite Centres.

There is an easy way to fix it.

Now that you understood the method, it is time to put in practice.

Begin with the first step: Solving The Centres.
