The process of restoring the Rubik's Cube is as follows: first restore the first layer, including the bottom and the four sides near the bottom surface, and then complete the second layer: the center, the edges around the center.

The third layer: cross to the top, cross to the side, cross to the top, to the four corners.

U: Above. D: Below.

R: Right. L: Left.

F: Front. B: Back.

R2: Turn the right side 180 degrees clockwise.

A single letter, for example: r is a 90-degree clockwise turn on the right side.

r' is the right side turned 90 degrees counterclockwise.

See the first layer, don't use formulas, solve it yourself.

The second layer is two steps:

1) For the center, it is easy to reconcile with the first layer of the restoration.

2) For the center edge, you can operate with the following formula:

Formula: r'u'r'u'

r'urur reference**:

Generally, the third layer is the top cross, the good cross (the overall view is the side cross, all the good), the top surface, the four corners.

Formula four: r'u'）f'

u2rur'ur

b'rf2r'

brf2r2

4.（ru'r）（ur

ur）（u'r'u'

r2) The formula you have to do is 3 for the top surface and 4 for the four corners.

If you want to learn the layer-first method explained by the formula of the Rubik's cube solution, you can learn it:

The third-order Rubik's Cube reduction method --- layer-first method (new - with picture).

The fastest main method to reduce the Rubik's Cube is CFOP (119 formulas):

First of all, to crack the Rubik's Cube, we must first understand its structure, the Rubik's Cube has a total of 6 colors and 6 sides, and each side is divided into ** blocks (6 blocks in the middle), corner blocks (8 blocks in 4 corners) and side blocks (12 blocks in the middle of 4 edges). Among them, there is only 1 surface of the ** block, and they are a fixed structure, so ** is a red block, so the other red colors must be concentrated on this face. And the red block is always opposite the orange block (as the international standard dictates).

The edge block has 2 faces and 2 colors, and the corner block has 3 faces and 3 colors.

Next, we'll represent each face with a letter, <>

Then the puzzle will use letters to indicate the 1 layer or 1 side to be rotated, as well as the direction: for example: r (for the right side to turn 90 degrees clockwise), r (to represent the right side to turn 90 degrees counterclockwise), r2 (to represent the right side to turn 90 degrees clockwise twice).

Here's the diagram:

Finally, it should be noted that the name of each side is relative, for example, f is the front, which is the side facing oneself when holding the Rubik's cube, if you rotate the imitation to the other side, then there is a new side to become the front.

Okay, let's try the next 7 steps to restore the Rubik's Cube!

1.First, the side with the white block in the middle (the one with the rubiks logo) is facing the top, and then make a white cross at the top, that is, the blocks of other colors are in the corresponding position (small complex, see the diagram, pay attention to the mantra marked above, do it correctly).

2 Then it's time to put the white corner blocks back in place (the cheats are very complicated, or it's easier to understand by looking at the picture).

3 Then let the middle edge block be homed.

Turn the white side downward, find the red and green side blocks, if the red and green edge blocks are on the top layer, then rotate the top layer in a clockwise direction until the side blocks are the same as the one in the diagram, and then turn the Rubik's Cube according to the formula to make the side blocks return to their positions. If the red and green edge blocks are in the middle layer, but the position or color is wrong, first make the red and green edge blocks in the front right position, and then rotate them again in one of the following orders.

4 Then adjust the top (which should be yellow) side block upwards to make a yellow cross. If the yellow cross does not appear on the top layer after 1 rotation of the formula, you can repeat the rotation until the yellow cross appears.

5 Then adjust the yellow corner blocks around the cross, which is a bit difficult, just look at the formula.

6 Usually at this time, the yellow block and the color of the side will be misaligned, according to the mantra (I haven't read it yet) to position the yellow block at the four corners.

7. Finally, adjust the color blocks on the edge to the corresponding position. Succeed with flying colors!! Get excited.

It took me a long time to get it done, so add a few more points!

The formula for the Rubik's Cube tutorial is (r u r' u' ）r' f）（r2 u' r' u' ）r u r' f'）。Marked with parentheses, the parentheses indicate a coherent set of techniques.

Uppercase letters r, u, etc. are to turn a certain face, and lowercase r, u, etc. are to turn two layers at the same time, belt'It's counterclockwise.

X, Y, Z is the whole Rubik's cube rotation, how to turn more around a little, X, Y, Z are horizontal, vertical and front and rear axes, marking X, Y, Z is respectively around these three axes clockwise rotation 90 °, plus'It's counterclockwise.

The Rubik's Cube has a total of 6 colors and 6 sides, and each side is divided into ** blocks (6 blocks in the middle), corner blocks (8 blocks in 4 corners) and side blocks (12 blocks in the middle of 4 sides). Blocks only have 1 face, they are a fixed structure, so if it is a red block, then all the other reds should be concentrated on this face.

1. The basic terminology of the six-sided Rubik's Cube.

Yellow side: upper, up u;

White side: bottom, down d;

Blue side: front, front f;

Green side: back, back b;

Orange side: left, left l;

Red side: right, right r.

2. Basic formula terms.

u: The top surface rotates clockwise; u': The top surface rotates counterclockwise;

In the same way: d, d'；f，f'；b，b'；l，l'；r，r'。

u2: The top layer rotates 180° clockwise; u'2: The top layer rotates 180° counterclockwise;

The same goes for other levels.

3. Rubik's Cube formula.

1.Bottom cross:

l'u'l2.Bottom surface reduction, four sides of the T-shape:

rur'uru'r

ru2r'u'rur'

3.The first two layers of the same color are restored:

The target block is on the top layer, and when it is rotated to be the same as the two layers below, it is placed on the right-hand side with the target at the back (rurur) (u'r'u'r')

The target block is on the top layer, and when it is rotated to be the same as the two layers below, place it on the right-hand side with the target in front (r'u'r'u'r')(urur)

If the other target blocks are in the middle layer, you can use the above two formulas to adjust them.

4.The top layer draws a cross:

Several states: a central point; Straight line state; Sharp angle state; Cross status.

f r u r'u'f'

At one point, the direction is arbitrary, and the sharp corners are out; The sharp corners are to the left back, and the top layer is in a straight line; Straight lines parallel to the body, with a cross drawn on the top layer.

5.Flip the top four corners:

All three corners need to be rotated counterclockwise, so that the second corner is yellow straight towards your own ru'u'r'u'ru'r'

All need to rotate clockwise, so that the first corner is yellow towards itself (rur'u)(ru'u'r')

When two corners, or even diagonal, one in the reverse rotation, follow the "two right" principle, one of the yellow faces the right hand, towards the right rear Use the above two formulas in order.

The four corners, following the "four back" principle, i.e. there are two yellow planes facing the rear at the same time Use the above two formulas in order.

6.The top four corners are restored sequentially:

Find a corner of the same color on both sides, with the yellow top facing you and the same color facing the right hand r2d2(r'u'r)d2(r'ur')

The appeal situation cannot be found on the side, and the yellow top side faces itself to make the formula and then adjust, and then make the formula.

7.Top-level prism restoration:

The three edges need to be cycled counterclockwise, placing the restored side on the back (ru'r)(urur)(u'r'u'r2)

Tri-edged, but cycled clockwise, placing the restored side on the back (R2'u)(rur'u')(r'u')(r'ur')

In other cases, feel free to do the first formula first, and then apply the first or second formula.
