Rubik's Cube is a three-dimensional mechanical puzzle created in 1974 by Ernö Rubik, an Hungarian sculptor and professor of Architecture

Rubik's Cube

1. It tests our mental ability2. It is educational, funny and entertaining3. It improves our capacity to process three-dimensional information.4. It tests our patience.5. It evaluates our memory.6. It is a challenge with oneself, since you will always try to do it as fast as possible.7. It reinforces hands agility.8. And much more...

Benefits of Rubik's Cube

1. 43 trillons. O more exactly, 43.252.003.274.489.856.000 is the number of possible configurations that can occur in Rubik's Cube.2. The God Number, the maximum number of movements to solve the cube is 20.3. “Speedcubing” is the name given to the sport, which consists of solving Rubik's Cube as fast as possible.

Our main objective was to take part in 3rd RUBIK'S Schools Competition

It was born in 2017.

Standard Notation

To complete the upper face by placing the four vertexes in place according to the lateral layers

Upper Face

It consists of making a cross on the white layer so that the colour of each face matches the center.

Upper Cross

This method consists of solving Rubik's cube by layers; first the upper one, then the lateral one, and finally the lower one. With a little practice Rubik's cube can be done in less than 2 minutes, and with a lot of practice you can even go down 30 seconds!

Simple Solution

U’ L’ U L U F U’ F’

U R U’ R’ U’ F’ U F

For this case we have to learn two simple algorithms. In order to carry them out, we look for an edge that does not have the yellow colour and we place it so that the colour of the edge matches the colour of the center.

Now we have to place the four edges.

To complete the second layer

Now a bit more difficult...

F R U R’ U’ F’ (x2)

F R U R’ U’ F’

Now we can find four cases and we are going to solve all of them with the same algorithm. Although it is not the most efficient solution, it is the simplest, then you can learn the rest of the ways to do it.

Now we don't care about the adjoining faces

Yellow Cross

The last face of the cube

U R U R’ U R U U R’ (x2)

U R U R’ U R U U R’

There are two cases:1. Two adjacent edges well placed at the bottom and left.2. Two edges well placed, but facing each other.

Now the cross must have the lateral colours the same as the adjoining faces.

To extend the cross

The last face of the cube

U R U’ L’ U R’ U’ L (x2 o x3)

U R U’ L’ U R’ U’ L

There are two cases:1. If a corner is in its right position, we leave it to the right.2. If no corners are in their right position, we apply the algorithm once to reach case 1.

To place the corners althought they may not be oriented.

Last vertexes

The last face of the cube

R’ D’ R D

Place a wrong corner to your right and apply the algorithm shown in the following image until the yellow colour is looking up. When that piece is ok, TURN THE UPPER LAYER to place another wrong corner to your right and re-apply the algorithm until the yellow is facing up. It is very important not to turn the cube during this process.Don't worry if it seems that you disassemble the cube!

Now we turn the corners to complete the cube.

Turn the Vertexes

You are about to finish!

Thank you!
