What formula is used to unify the color of the top layer after the top layer of the Rubik s Cube is

Attached: <>

Complete the top layer. a) Top layer cross.

After completing the second layer, the top layer will have the following three situations:

For the above three cases, we only need to remember one formula, which is:

Formula mumumuum'um'um'uu

Our ultimate goal is to make the top surface look like this.

If the top surface of your Rubik's Cube is already like this, then this step can be skipped directly, but not every time you will be so lucky, the formula still needs to be memorized. The following are the top three states and twisting methods.

Top view: black indicates a yellow block.

2) Top-level plane.

The first formula (left-handed formula): L'U'Lu'L' U2L

The second formula (right-handed formula): rur'uru2r'

7 situations encountered after twisting the top layer of the Rubik's Cube into a cross.

c) Top layer corner block.

After the top color of the Rubik's cube is unified, we begin to restore the position of the corners of the Rubik's cube, first turn the top layer of the Rubik's cube, find the two corner blocks in the correct position, put the side with the two corner blocks on the palm of the right hand, and then use the following formula to rotate the Rubik's cube to restore the corner blocks to the correct position.

Formula r2f2r'b'rf2r'br'

If there are no two corner blocks in the correct position, we can rotate the top layer of the Rubik's Cube, put the two corner blocks in the correct position on the diagonal, and then find one side and twist the above formula to get two corner blocks in the correct position on one side.

4) Top layer edges.

1.Start with the left-hand formula, turn the Rubik's Cube, and do the right-hand formula.

2.Start with the right-handed formula, turn the Rubik's Cube, and make the left-handed formula.

3.In these two cases, first find a side to make a left-handed (right-handed) formula, and then turn the Rubik's Cube to make a right-handed (left-handed) formula, you can get the above situation, and then restore it.

The Rubik's Cube has been restored!

The modus operandi of these seven situations. Found online.

If you only use two formulas and repeat it, you have to put it in the right position.

The following is the one in the Rubik's Cube Paradise, I hope you can use it.

The simplest formula for the restoration of the top 7 cases of the third-order Rubik's cube:

First, the top layer makes a cross of the same color: r' u2 r u r'u r second, to bring the corner blocks of the same color into place: r' u'r u'r'U2 R The third way to make the middle layer edge block home:

r u2 r' u' r ur' u' r u' r'

Fourth, to return the top edges: R2 d' r u2 r'D r u2 r fifth, so that the top layer of the edge is in place: xur'u'lur u'r Sixth, so that the corner blocks of the top layer are put in place:

r u'u'(r'2 u')(r2 u')r'2 u' u'r

Seventh, make the top layer of the corresponding corner block homecoming: (l u' l')y(r u r u' r)

Answer: Take one side of one of the colors to yourself (e.g. red) and the yellow side to face up, frur"f"frur"f"。

Formula after the top cross:

r' u2 r u r' u r

x'(r u'r) d2 (r'u r) d2 r2

r u 'r) u (r, Fan Duo, Yi Huan, Wei Fan Li, u r u') (r' u' r2)

Follow these three formulas to complete the restoration.

1. The English name is rubik'S cube, also known as the Rubic Cube, is an extreme hand sport.

2. It usually refers to the third-order Rubik's Cube. The third-order Rubik's Cube shape is usually a cube and is made of elastic hard plastic.

3. The racing game is to disrupt the Rubik's cube and then restore it in the shortest possible time.

4. The Rubik's Cube was first invented in 1974 by Professor Erno Rubick of the Budapest School of Architecture, Hungary.

The color of the first layer is the same, and the color of the side of the first layer is the same as the color of the side of the Rubik's Cube 4.

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.

The third level of the formula (also four corners): right straight - upward straight - right reverse - upward reverse - right reverse - forward - right straight 180° - upward reverse - right reverse - upper reverse - right straight - right reverse - forward reversal.

The third level formula (also centered): right straight - upward reverse - right straight - up straight - right straight - upper shun - right straight - lower reverse - right reverse - upper reverse - right 180°

Third-order Rubik's Cube: It consists of a central axis connected to six central blocks, 8 corner blocks, and 12 edged blocks, which when connected together form a whole, and either side can rotate horizontally without affecting the other blocks. The third-order Rubik's cube is the most common in life, and in March 2011, a new type of third-order - bread third-order appeared, breaking the conventional design of the third-order Rubik's cube.

Top cross (color) bottom left, top left, front right, top right, front left, top left.

Top Corner Block (Color) Left Hand: Top Left, Top Right, Bottom Left, Top Right, Top Left, Top 180, Bottom Left.

Right hand: upper right, upper left, lower right, upper left, upper right, upper 180, lower right.

Top corner block (position) Left hand: Left 180, Front 180, Lower Left, Back Left, Top Left, Front 180, Lower Left, Back Right, Lower Left.

Right hand: Right 180, Front 180, Lower Right, Back Right, Top Right, Front 180, Lower Right, Back Left, Lower Right.

Top Layer Prism (Position) Left Hand: Top Left, Top Right (followed by the second layer Left Hand formula), Bottom Left.

Right hand: upper right, upper right (followed by the second layer of right-handed formula), lower right.

The top-level cross rotation method of the third-order Rubik's cube:

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.

There is only one formula for the top layer of the cross, which is frur'u'f', that is, the front layer turns 90 degrees clockwise, the right layer turns 90 degrees clockwise, the top layer turns 90 degrees clockwise, the right layer turns 90 degrees counterclockwise, the top layer turns 90 degrees counterclockwise, and the front layer turns 90 degrees counterclockwise.

Bottom right (front left), left (front right), top up.

After spelling it into a cross.

Bottom right, top right, bottom right, top right.

The top surface is spelled out. Up (back right), up (front 180), down (back left), up (front 180) (right 180), and finally up, right, up, left, up, left, right, right, down, down.

Front clockwise, right clockwise, top clockwise, right counterclockwise, top counterclockwise, front counterclockwise.

There are three cases: blue is the front, red is the right, and yellow is the top.

Can I send it to you in PPT?

Inside is a solution using words and images. It should be very detailed.

Really want to learn the alphabet, the alphabet wants English to know the English before, after, left, right, up and down English, and the alphabet is the first of their beginnings.

Upper Right, Upper Left, Lower Right, Upper Left, Upper Left, Upper Left, Lower Right, The upper layer is the "fish head", and the formula is repeated up to two times! The top layer is turned!

Then capped.

Formula: Top Right, Top Left, Bottom Right, Up Left, Top Right, Top Left, X2 Bottom Right.

Next, restore all the top faces, and then restore the side ones. Here's the formula.

Hello, if you only put together the cross, then there are still four corners away from putting together the first layer. The second step should be to put together the first layer! The cross is facing upwards and recovering corner by corner.

First of all, you just need to look at the corner block, then find the corner block that you need in the upper right corner of the magic side facing you, just rotate the bottom layer so that the corner block is on the right side facing you, it doesn't matter above and below, and then use the formula r'd'r.It's OK (sometimes the corner block you need will be on it.,And then the direction is the same.,You use that formula and it will come down.,I suggest that the bottom corner block first restore the position.,The first answer to that person.,He said the third step.,You can do the third step according to him.,I hope it helps you.,If you don't understand anything, just ask) I'm on the subway.,Mobile phone typing.。

Use the formula "Forward Straight, Top Right, Top Straight, Right Bottom, Top Reversed, Forward Reversed". Pay attention to the placement of the Rubik's Cube.

1. Play the color of the first layer consistently, and make the color on the edge of the first layer consistent with the color on the side of Rubik's Cube 4.

2. The second layer of formulas: upward - right - upward - right - upward - forward - upward - forward - upward - forward 3, the third layer of formula (from the cross): right reverse - upward reverse - forward reverse - upward - forward - upward - forward - right - the third layer of formula (four corner blocks):

Right Shun - Shang Shun - Right Reverse - Shang Shun - Shang Shun 180° - Right Shun - Right Reverse.

4. The third layer of formulas (also four corners): right Shun - Shang Shun - Right Reverse - Upward Reverse - Right Reverse - Forward Shun - Right Shun 180 ° - Upward Reverse - Right Reverse - Upper Shun - Upper Shun - Right Reverse - Forward Reverse The third layer formula (also center): Right Shun - Upward Shun - Right Shun - Right Shun - Upper Shun - Right Shun - Right Shun - Lower Reverse - Right Reverse - Upper Reverse - Right 180°

Use the formula "Forward Straight, Top Right, Top Straight, Right Bottom, Top Reversed, Forward Reversed". Pay attention to the placement of the Rubik's Cube.

Don't worry, that's the last step of adjustment, and your next step should be to restore the top surface

1. As shown in the figure below, the yellow cross on the top layer has been completed, and the color of the blue and yellow block does not match the orange block in the center, taking this as an example.

2. Rotate the rightmost layer by 180°, and we can see that the yellow and blue blocks are at the bottom layer.

3. Rotate the lowest layer, the layer where the yellow and blue blocks are located, until you find the blue center block.

4. After finding it, rotate the Rubik's Cube as a whole so that the matching blue and yellow blocks and the blue center are on the far right.

5. Rotate the rightmost layer 180° to complete. Other mismatched top-level crosses and center blocks, and so on.
