I wish you a speedy success! It's not very clear to say the details.

The easiest tutorial for newbies to play the third-order Rubik's Cube:

1. The "center block" is the small square in the center of each side of the Rubik's Cube, there are 6 in total, and they have only one color on them, which means that it cannot be reversed, and its color determines the color of the restored surface where it is located. The red center block determines that the entire surface it is on will be red after the restoration in the future.

2. "Edges", as the name suggests, is a block on the edge, there are four edges on the first layer, a total of 12, and they have two colors on them, which means that they can be flipped at two angles. For example, the "blue orange" ridge will have two flip angles, either orange on top and blue on the side, or blue on top and orange on the side.

3 "Corner blocks", because they are on the 8 corners of the Rubik's cube, therefore, we call them "corner blocks". There are 8 "corner blocks", and each of them has three colors, which means that they can be flipped at three angles. For example, the "red-green-yellow" corner block can be red, green, and yellow on it, that is, it has three angles.

Once we understand the components of the Rubik's Cube, we need to identify two faces, one is the "bottom" and the other is the "top". We place the Rubik's Cube flat on the table, and the side next to the table is called the "bottom side", and the top side facing it is called the "top side".

You can refer to any face as the "bottom", and the face opposite it is the "top". In my tutorial, the white side is the "bottom surface", and the opposite side, the yellow side, is the "top surface". To put it simply, the white side is always on the bottom and the yellow side is always on the top.

Finally, let's agree on a few terms in this tutorial. The first is "dial", the "dial" of the left hand is to use the index finger of the left hand to pluck the top layer, so that the top layer turns 90 degrees counterclockwise; In the same way, the "dial" of the right hand is to use the index finger of the right hand to pluck the top layer, so that the top layer turns 90 degrees clockwise.

1. The six sides of the Rubik's Cube are divided into six faces: upper, lower, left, right, front and back, which are represented by the letters U, D, L, R, F and B, and the bottom layer, middle layer, and top layer.

2. Establish a datum bottom, such as using red as the datum bottom, that is, the middle one is red as the bottom surface.

3. After selecting the bottom surface, turn the bottom surface into a cross shape. Turn the front and back sides to the same color as the bottom layer corresponding to the red cross on the bottom.

4. Turn the red corner corresponding to the bottom surface to the front right, and use the formula to turn it to the bottom color. The same goes for the other corners, turning the bottom surface into one color.

5. When rotating the middle layer, first turn the color of the upper layer and the middle layer to the same, turn it to the right or left side, and then use the formula five straight and four reverse or five reverse and four straight, and the other angles are the same, and the middle layer can be restored.

6. The top layer is also the least good layer, first use the formula to turn the top surface into a cross shape, if you do not succeed in trying several times, as long as the cross appears, you can restore the top layer several times.

7. Restore the four corners and four sides of the top layer, turn one side and one side and turn away to yourself, and use the remaining three sides with a formula, use a few more times to turn the side well, pair one of the corners, and then turn the whole Rubik's Cube to yourself 90 °, use the formula to turn the corners well, and the whole Rubik's Cube will be completely restored.

1. There are many ways to reduce the Rubik's Cube, among which the "layer first method" is the most suitable method for beginners to master.

2. A third-order Rubik's Cube, "from top to bottom" can be understood as "top", "middle", and "bottom", and the so-called "layer-first method" is to restore layer by layer.

3. The restoration of the third-order Rubik's Cube layer "layer first method" is divided into the following 6 stages: for the top layer cross, the top layer of the edge is restored; Restore the top layer corner block; Restore the middle layer of the edge.

4. Restore the bottom edge of the bottom layer of the cross at the bottom layer; Flip the bottom corner blocks to align the bottom color; Adjust the position of the bottom corner block to complete the restoration.

1. The bottom cross.

To complete all 12 edges, the first step is to put together a cross and complete the first four edges. And make the color of the cross uniform with the color of the center block around it. The cross can be groped for itself.

It doesn't take too difficult skills to complete the cross alone. As long as you have a certain amount of spatial imagination and logical thinking ability, plus a certain amount of time to study, there is no problem in completing the cross independently.

2. A middle layer of edges.

After completing the cross, the next step is to flip the entire cube so that the yellow side is facing up, and complete the edges of the middle layer. The edges of the second layer can also be derived on their own.

3. Top-level cross.

If the last edge does not appear in the middle layer, then there must be a yellowish edge inside the slot. So let's go to the top layer (r) first, and then dodge, (you or u.)'or u2) to return the scrambled edges (r'）。

4. A top-layer prism.

The most basic situation we have to deal with is that the back has been restored and the front 3 edges need to be rotated. Here is the formula first, and the author will give an analysis later. It can be a bit tricky to understand this step at first. But it is still advisable to look at the derivation formula.

Clockwise three rotations: r'u'ru'r'u2r。This is the small fish formula used in the layer. The formula for counterclockwise substitution is symmetrical with its mirror image: lul'ulu2l'。

5. Top-layer corner block - replacement.

Finally came to the corner block. Let's take a corner block as an example. Rotate the top layer (remember to turn only the top layer) so that the corner block is below the target position.

Now let's forget about everything except the top layer and this corner block. Let's abstract the problem and see what to do with this corner if it were a one-sided piece. The old routine is to move this corner block to its target position, then dodge it, leave a slot for the top edge to come back, and finally return the block to its position.

The specific steps are as follows:

Tools: You need to prepare a third-order Rubik's Cube.

1. First of all, build the top layer of the cross and take the knurling, complete the restoration of the bottom layer, and complete the return of the edges of the second layer.

2. Restore the third layer of the top layer cross, complete the two simple cases of the same angle of the top surface, and complete the other five cases of the top surface color.

3. Then return to the four corner blocks of the third layer, restore the third layer of edge blocks, and it can be completed.

4. Set up a cross at the top, and adjust all the four top edges of the Rubik's Cube to the top surface with the same color as the top surface. At this point, there may be 4 situations: when we encounter a "point", it will be a "small turn" after the action, and then "one word", and finally a "cross".

In this way, the top cross of the third-order Rubik's Cube is turned out.

Extended information: 1. The general reduction method of the third-order Rubik's cube: layer first method, most beginners choose the layer first method, which is characterized by few formulas and easy to understand, and the general steps are as follows:

1) For the top layer of the cross, restore the top layer of the edge;

2) Restore the top layer corner block;

3) Restore the middle layer of the edges;

4. Restore the bottom edge of the bottom layer of the cross at the bottom layer;

5) Flip the bottom corner block to align the bottom color;

6) Adjust the position of the bottom corner block to complete the restoration.

2. Advanced reduction method: CFOP method, which is the method used by most racing players, can restore the six sides of the Rubik's Cube within 30 seconds after proficiency, approximate steps:

1) Cross at the bottom layer;

2) There are 41 cases for completing the first two layers (F2L);

3) Top surface reduction (OLL);

4) Top Surface Reduction (PLL).
