How to spell the first layer of the Rubik s cube, and how to put together the complete Rubik s cube?

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 will use a letter to represent each face, and then we will use a letter to indicate the layer or side to be rotated, and the direction: for example:

r (represents the right side clockwise 90 degrees), r (represents the right side 90 degrees counterclockwise), r2 (represents the right side turns clockwise 2 times 90 degrees) 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 put the white block in the middle (the one with a rubiks logo) on 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 the white corner block is in place (the cheats are very complicated, or it is easier to understand by looking at the picture)3 Then let the middle side block be in place.

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 to the cross, a little difficult, look at the formula tips6 Usually at this time, the yellow block, and the color of the side will be misaligned, according to the formula (I haven't read it thoroughly) to position the yellow blocks at the four corners 7 Finally, adjust the color blocks on the side to the corresponding position. Succeed with flying colors!!

Get excited.

This is slow and troublesome, let me tell you the method, the following 'angles' are the four corners of a face, and the 'edge' is the four sides of a face, which is the one sandwiched by two angles;Spell a cross first, the color should be right, red to orange, blue to green, and what is red on the left and right, all right, so that there are four corners, according to the color position on the right to get it, hopefully.

Okay, I'll ask Chen Nan to tell you.

There are three ways to layer first corner first edge first as a beginner, it is best to learn the first layer method is to say that the first layer of the first layer of the way is not unique, so there is any way, I suggest you play by yourself first, practice spelling a face. If you have any questions, feel free to ask.

Simply put together a shuffled Rubik's cube into a flower of the same color.

2. Turn the cross flower to make it a cross of the same color. Note that the center point matches the color of the sides when turned. This is shown in the figure below.

3. The top surface is also put together into a cross. Of course, there are also many crosses with several of the same color on them. The following two figures are shown.

4. Complete the top surface color turning. Uniform top color. Don't worry about the side color of the top layer.

5. Adjust the position of each color block and turn it to the correct position.

There are tutorials for general Rubik's cubes.

The first step is to make a green cross at the top. Available formulas: (right reverse, upward straight, forward reversed, upward inverse) Here reverse refers to counterclockwise, and forward refers to the forward pointer. The Rubik's Cube is divided into up, down, left, right, front and back, so the above situation will occur.

First, find the green in the center, then use this green as the center, find the four green edges around him, and finally put together a green cross. If you want to make this green cross, you have to find it from the green edge in the middle.

The second step is to make the green corner blocks back into place. Available formulas: (Right Reversed, Reverse Down, Straight Right, Straight Down) The formula can be repeated multiple times.

The third step is to return the middle edges. This can be both.

The formula for the first case is: (Ascend, Right, Ascend, Right, Right, Ascend, Forward, Ascend, Ascend).

The formula for the second case is: (upward reversal, forward reversal, upward order, forward order, upward order, right order, upper direction, right reversal).

The fourth step is to put the top edge back into place. Available formulas: (Forward Straight, Right Straight, Up Straight, Right Inverse, Up Inverse, Forward Inverse).

The fifth step is to put the top edge in place. Available formulas: (Right Straight, Ascend, Right Reversed, Ascended, Right, Ascended, Reversed).

The sixth step is to return the corner blocks on the top layer. Available formulas: (Ascend, Right, Upward, Left, Ascend, Right, Ascend, Left).

The seventh step is to return the top corner blocks to their positions. Available formulas: (Right Reversed, Reverse Down, Straight Right, Straight Down) can be repeated multiple times.

At this time, you must pay attention to holding the Rubik's Cube, which is the red side in front, turn the top layer clockwise (up and down), and then turn the corner that needs to be rotated to the upper right position.

There are many ways to reduce the third-order Rubik's Cube, among which the "layer-first method" is the most suitable method for beginners to master. A third-order Rubik's Cube, "from top to bottom", we can understand it as "top", "middle", and "bottom", and the so-called "layer-first method" is to restore layer by layer. The third-order Rubik's Cube "layer first method" is restored, which is divided into the following six stages:

The first stage]: the top layer of the cross, restore the top layer of the edge. [Phase 2]:

Restore the top corner block. [Phase 3]: Restore the middle layer of the edge.

The fourth stage]: the bottom cross, restore the bottom edge. [Stage 5]:

Flip the bottom corner block to align the bottom color. [Stage 6]: Adjust the position of the bottom corner block and the restoration is completed.

How to put the Rubik's Cube together is in a certain order.

1. Turn out a cross at will;

2. Front and right homing (up right up and right up and backward and forward forward), front and left homing (up and left up and up and backward);

3. Top cross homing: right down, left forward, backward left, front left, and right up (1-4 times);

4. Top-level homing: bottom, left, right (2 or 4 times), upper right bottom, left and right, right and upper right (2 or 4 times);

5. Top angle homing: upper right back lower right upper front 180 ° lower right back upper right upper front 180 ° right 180 °;

6. Top-level restoration: 180° from right to right, right to right, left to right.

The last piece of the Rubik's Cube is directly straightened.

Normally, there will be no leftover pieces.

If it appears, it means that the Rubik's Cube is wrong.

Don't tell me how it was.

Anyway, it's wrong now.

Straighten it directly. It is not possible to restore with formulas.

1. The first layer: the bottom edge is in place (also known as the bottom frame cross, the process of correct restoration of the bottom four edges) The bottom shelf of the Rubik's Cube can be self-taught, but the relative position order of the four edges to be restored in this step should be noted because we use the white center block as the bottom layer, according to our current mainstream Rubik's Cube sticker method (yellow on the bottom, white on the front, blue on the front and green on the back, orange on the left and red on the right), if we first restore the white and blue edges. 2. Then we keep the white center block at the bottom, the white and red squares should be placed on the right side of the white and blue squares, the white and orange squares are placed on the left side of the white and blue squares, and the white and green squares are placed on the opposite side of the white and blue squares.

3. Then rotate the top layer of another color (blue or red or green or orange) to make it the same color as the corresponding center block, so that we rotate it 180 degrees, and the corresponding edge will be correctly restored to the bottom. Nuclear tank.

In the Rubik's Cube formula, the top-left-bottom, left-up, left-left, bottom-left are the reduction methods of the second layer.

The standard names of the 6 planes of the Rubik's Cube used in the whole process of solving the Rubik's Cube are as follows:

Top: Top plane (choose your favorite color).

Front: Front plane.

Left: Left plane.

Right: Right plane.

Bottom: The bottom plane.

Rear: The posterior plane is --- and rarely used.
