Rubik's cube: the third layer

The third layer
of the 3x3x3

Home - Conventions - 1^st layer - 2^nd layer - 3^rd layer

As you have understood, the cube will be finished at the end of this step.

This is 4 parts:

   1. Make cross
   2. Targeting cross
   3. Place wedges
   4. Orient corner

To begin, you must turn the cube on 2 layers made downward.

1 - Make the Cross:

At the end of this stage
your cube should look like this:

In this step, do not worry about colors on the sides. Only the color of the cross (here, yellow)!

2 options available to you:

a) - The edges are opposed:

This formula will switch the left and right edges to the center:

Use the following formula:

U F R U R' U' F'

b) - The corners are not opposed:

This formula will switch the front and right edges to the center:

Use the following formula:

F U R U' R' F'

It is possible that some edges are already installed properly. You then have the chance.

The cross is now finished:

Rubik's cube: la troisième couronne

2 - Targeting the cross:

The goal is that your cube
look like this:

To focus the cross, you can apply a single formula. This will rotate the bones (except the one in front of you) in the sense of a clock hand.

Use the following formula:

R U U R' U' R U' R'

You can apply this formula several times, but a little reflection you see when rotating the upper judiciously, the formula can be applied only once!
With a little practice, you will see that it is easy to do.
Example:

In the left example, if you apply the formula, you put the orange face (right) instead of the blue (left) and blue instead of green (behind). Only 2 faces are positioned correctly (red and green). It is not good!

After reflection, turn your face orange cube in front of you and rotate the upper surface to align the orange edge facing you (right figure). Now, if you apply the formula, all edges are properly positioned.

At the end of this stage
your cube will look like this:

3 - Place the corners:

At the end of this step, your cube should look something like this:
The "something" is important because the orientation of parts may vary. What matters is the location (the 3 colors on each corner corresponds to the 3 sides of the corner)

The formula will rotate around (except the one placed in front of you right) in the sense of a clock hand.

To rotate the corners, use the formula:

L' U R U' L U R' U'

In this case, I had to put the orange face before me as the corner yellow / blue / orange was already done!
Depending on your configuration, you should apply the formula 2 foix up!

In my case, the 4 corners are well placed and 2 are already correctly oriented (2 front).

4 - Orient the corners:

After this step, your cube is finished!

Continuing the example above,
your cube should look something like this:

The formula allows you to switch up the 2 corners of your right.

Use the following formula:

R U U R' U' R U' R' L' U U L U L' U L

Depending on your configuration, you can repeat this several times.

Normally, your cube is finished!

Congratulations !!
