Basics

The process of solving the cube is very simple. All you need is a little logic, thinking capacity and a cube :P
To make things even simpler i will divide the process into smaller sections which will enable you to proceed step by step, and not jumble everything up.

Firstly, let me tell you about the Rubik's Cube:

The above picture is of a Rubik's cube (solved).

The Rubik's Cube is a 3-D mechanical puzzel invented in 1974 by Hungarian sculptor and professor of architecture Erno Rubik. Originally called the "Magic Cube", the puzzle is considered as the "puzzle of the century".

In a classic Rubik's Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally white, red, blue, orange, green, and yellow). A pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be a solid colour.

This is a simple cube with a 3×3×3 dimensions. There is another puzzle called the professor's cube, it has a dimension of 5×5×5, and it is (obviously) more challenging than a Rubik's Cube.

This is a professor's cube

Now, let's not get carried away and get back to the task already at hand.

Observe the next set of diagrams carefully, these terms will be often used and hence its mandatory to go through the following set of diagrams.

These are the layers in the cube. You will first solve the first layer and then the second layer and then the 3rd layer. (I know it sounds obvious)

This is how it will look after solving the first layer.

Here the black colour is just to show that those squares can be filled with any colour.

Solving the second layer will give you the follow combination in the cube:

Here again, white coloured squares are just to show that they can be filled with any colour stickers.

And then solving the final layer will give you a solved rubik's cube.

I wish to divide the steps as following:

1) Top layer edges.

2) Top layer corners

3) Second layer

4) Third layer edges

5) Third layer corners

6) Third layer orientation

Now if you are confused with the terms edges and corners, I hope the next set of pictures will help you understand.

The center's of the cube are the colours at the middle of each side of a cube:

The coloured portions are called the center

The edges of the cube are the middle piece of each side:

The coloured portions are the edges

Each edge contains only 2 colours.

The end pieces of each side is the corner:

Again, the coloured portions are the corners

Each corner is made up of 3 colours.

A important point to note is that the center of the cube is always stationary and we have to try to get all the colours to their respective center.

In my next segment I will be teaching you how to solve the top layer edges.

I suggest you to have a rubik's cube with you while you go through the instruction, so that you can try solving it while reading the instructions, or you could note all the instructions in your head (that works if your name is Einstein).
