Urgent Rubik s Cube Formula, High Score Heavy Thanks!!

I just played Rubik's Cube recently, so I'll tell you how I feel. The Rubik's Cube I bought back came with an explanation, but I think it's relatively easy to play to the third step. After the fourth step (top-level restoration), it is not possible to read the manual, and then I figured out how to use those formulas, and I played when I had time, and I became proficient while playing.

I wanted to write it myself, but unfortunately I couldn't type it myself.

There are some formulas, the formulas of the first 3 steps are relatively simple, and it is easy to turn without how to memorize and understand, mainly to restore the top layer later, and it takes a few more exercises to remember.

You can change the r, l, and u inside to left, right, up, down, etc.

r-right l-left u-up d-down f-front b-back What is not dotted is clockwise, and what is dotted is counterclockwise. Column: Equation 2-1: (r u r'I'll just remember that it's right straight, up straight, right reverse, hehe.

Personally, I think it's more detailed. You should be able to understand it, and you can be proficient by touching the Rubik's Cube more. Hehe.

Well, it's the top cross under the formula under the standard case (four top corners, three missing); Place one vacancy on the near side and the other two on the far side.

If you do it with your right hand, it is: up and down, up and down.

The formula on the left-hand side is: upside down, upside down, top upside down.

Buy "Rubik's Cube Paradise", very detailed, yuan.

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" can be understood as "top", "middle", "bottom", the so-called "layer first" is layer by layer reduction.

The second level of formulas: upward straight - right straight - upward reverse - right reverse - upward reverse - forward reverse - upward straight - forward straight.

The third level of the formula (starting cross): right reverse - upward reverse - forward reverse - upward straight - forward straight - right straight.

The third layer of the formula (four-corner block): right shun - upward shun - right reverse - upper shun - upper shun 180° - right shun - right inverse.

It's been a long time since I've spelled a Rubik's Cube, and today someone suddenly asked, so let's talk about it. (My best time is 1 minute 15 seconds).

The first layer: The first layer is self-taught, and it is very simple. Let's not talk about it.

The first layer and the first side are put together synchronously.

Second layer: Place the full side side down. Then align the middle of the second layer with the first layer to form a small inverted T-shape. Realign the middle of the third layer.

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is green above.

Use the left-shift formula: up-left-up+left+up+front+up-front-(up, down, left, right, front and back.) + refers to 90 degrees clockwise, - is the opposite, 2 fingers to 180 degrees).

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is yellow on top.

Use the right-shift formula: Up+Right+Up-Right-Up-Front-Up+Front+

When the second layer appears, the right side of the front is yellow. The second layer on the right and the left are blue with shortcut formulas.

Quick formula: Right + Up 2 Right - Up + Right + Up 2 Right - Up + Front - Up - Front + +

And so on, put the second layer together.

Third layer: After the second layer is put together. There will be 4 situations on the top surface (we will spell the word "ten" on the top surface next):

1.There is only one top color in the middle. Use the cross formula over and over again. Appearance 2

2.The top surface forms a top color. Turn the top face to turn the line into a vertical line. Use the cross formula again. Appearance 3

3.The top surface forms a right angle. One side up, the other side down. Use the cross formula again. Appearance 4

4.A "ten" word (needless to say in this case).

Cross formula: right-up-front-up+front+right+

Then the color. (The third layer is the same color as the side).

Color matching formula: right-up-right + up-right-top 2 right + top 2 Effect: The color of the top layer on the left remains unchanged. The remaining three sides of the middle color rotate counterclockwise.

until the color is the same in the middle of the four sides.

After the top cross is put together. Here are three formulas to spell out the top surface:

1.Left + Right - Up - Right + Up + Left - Up - Right - Up + Right + Effect: The top right corner of the top surface does not move. The lower right corner flips to the top of the upper left corner, the upper left corner flips back to the bottom left corner, and the lower left corner pans to the lower right corner.

2.Front + Right - Front + Left 2 Front - Right + Front + Left 2 Front 2 Effect: The top right corner of the top surface does not move. The rest of the triangles are translated counterclockwise for one round.

3.Left + Right + Up 2 Left - Right - Back + Front + Up 2 Back - Front - Effect: It's hard to say, just use it once after the six sides are good (this is also a shortcut formula).

If there's anything else you won't be able to ask me at any time.

Rubik's Cube cheats: As long as 7 steps, you can restore 6 sides.

Any intricate 3*3 Rubik's cube can be restored in just 7 steps!

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 letters to represent each face, and then we will use letters to indicate the layer or 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 clockwise 2 times 90 degrees).

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, put the white block in the middle (the one with the rubiks logo) on it, and then make a white cross at the top, that is, the other colored blocks 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 blocks are put in place;

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!

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

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