CUBE RESOLUTION GUIDE 2x2x2

The goal of this guide is to teach you how to solve the Rubik's Cube in the easiest and most understandable way possible. It is not very difficult to learn, but it requires concentration, memory and spatial vision.

Before starting the resolution, take a look at the Notation 2x2x2 section, you will find the basic concepts to know to start solving it.

Notation 2x2x2 cube

The resolution consists of 3 steps:

• Step One : Solve the first layer of the cube.
• Second Step : Orient the second layer.
• Third step : Swap pieces in the second layer.

FIRST STEP

In this first step we will have to solve the first layer of the cube, as we see in the pictures. It will not be enough for an entire face to be the same color, but the colors on the side of the piece will also have to match.

In this guide we will start with the white layer, so first of all we must choose one of the corners that is white, orient the cube so that the white looks up and make the piece is at the top left of the front face.

Once we have the piece located and the cube oriented, we must look for the corner next to it and place it so that it is below its correct position.

In the picture we can see an example. The piece chosen was the white, red and green, and next to it is the piece, white, blue and red. This piece is placed under its place and the cube is oriented correctly using the color red as the front face.

We will have to repeat the same procedure with all the white corners to end up achieving the goal of this first step.

We can find 4 different situations to put the corner in its place:

First situation:

With the two pieces placed and the cube oriented correctly, the white color of the corner to be placed is on the front face.

The moves we need to make in this case are as follows:

Second situation:

With the two pieces placed and the cube oriented correctly, the white color of the corner to be placed is on the right side.

The moves you need to make in this case are as follows:

Third situation:

With the two pieces placed and the cube oriented correctly, the white color of the corner to be placed is on the underside.

Once we have performed the following algorithm, you will be left with the cube in the second situation:

Fourth situation:

The piece is in its proper place but is not well oriented and the colors do not match the rest.

We will repeat the following algorithm until the piece is oriented correctly. We will have to repeat it 2 or 4 times, depending on where you are looking at the white color of the corner.

In the case of the example image, as the white looks at the front face we will have to do the algorithm 4 times.

If the target is facing right, we should do the algorithm twice.

SECOND STEP

In this second step, first of all we have to turn the cube, the white face must be facing down.

The goal is to make sure that all the corners of the second layer, which we now have at the top, are well oriented, that is, with the yellow facing up.

In this step we will only have to use a single algorithm, but we may have to repeat it several times.

First of all we have to orient the cube correctly and then perform the algorithm noted below. If the yellow face is not complete, we will reorient the cube and re-perform the algorithm. We may need to repeat the algorithm more than 3 times.

How to orient the cubeThe cube notation

Case 1 : If only one of the corners is yellow facing up, we orient the cube so that this corner is at the top left of the front face, as shown in the picture. He then performs the algorithm.

Case 2 : Conversely, if one or more corners have yellow facing up, we orient the cube so that the piece on the top left of the front face is yellow facing the left face, in the pictures we can see 2 examples. We then perform the algorithm.

We can move the top layer of the cube freely to look for one of the two situations mentioned.

THIRD STEP

In this last step we will only have to perform at most 2 times the algorithm shown below.

To do this we must orient the cube correctly.

How to orient the cubeThe cube notation

Case 1 : Turning the top layer we must be able to solve one of the side faces (green, orange, red or blue). We have to place this resolved face on the back, with the yellow layer on the top and the white one on the bottom.

In the example image we can see how the blue face is completely solved, we have to place this face on the back to perform the algorithm.

Case 2 : It may happen that by moving the top layer we do not get a side face to be completely resolved, in this case we have to perform the algorithm with the yellow layer at the top and the white layer at the lower part, using any of the side faces as the front face. Once done, we can move on to case 1.
