What is the formula for the third layer reduction of the third order Rubik s Cube? To letters.

The third level of formula is divided into two steps, step one is to restore the color of the top surface, and step two is to restore the position of the corner blocks and edges of the top surface, that is to say, after the end of step two, the entire Rubik's cube will be restored. I don't know what formula you want, I suggest you go or search for an introductory tutorial in the space, the details are detailed, and the formulas are complete.

First, make a white cross;

2nd, the first layer of formulas: right, up, right, up, right, right, up, up, right;

3rd, the second layer of formulas: right, up, right, up, right, up, up, right

4. The second layer of the formula is reversed: right inverse, upward inverse, right inverse, upward inverse, right inverse, upward shun, right shun, right shun, right shun;

The 5th and third level formulas: right order, upward order, right reversal, upward order, right order, upper order, upper order, right reversal.

The formula for the reduction formula of the third-order Rubik's cube is as follows:

Formula 1: "Up, Left, Down, Right, Up" After aligning the bottom cross, then find any two adjacent sides, the upper part of each side has the same color, apply this formula to make the four sides, the two colors of the upper part of each face the same, mainly to deal with the color of the edges.

Formula 2: "Up, Left, Down, Right", after the bottom cross is done, turn the cube 180 degrees, the bottom side is facing down, and through this formula, the color of the bottom surface is all done.

Formula 3: Move the top to the left, the right hand does "up, left, down right", the cube turns 90 degrees to the left, and the left hand does "up, right, down, left". This is to find the top layer without a light yellow block, align one of the color strips, look at the color of the other side, if this color is the same as the color of the center block on the right, you can use this formula.

Formula 4: Move the top to the right, the left hand does "up, right, down, left", the cube turns 90 degrees to the right, and the right hand does "up, left, down, right". This is to find the top layer without a light yellow block, align one of the color strips, look at the color of the other side, if this color is the same color as the color of the center block on the left, you can use this formula.

Formula 5: Rotate the front 90 degrees clockwise, apply the formula "up, left, down, right" and then rotate the front 90 degrees counterclockwise. This mantra is used to make the "top cross".

Formula 6: "Down, right, up, right, down, right, up" This formula mainly makes the shape of a small fish at the top, and then continues to make all the colors of the top surface.

Formula 7: "Top right, 180 degrees clockwise below, 180 degrees clockwise on the bottom left, 180 degrees clockwise on the bottom, 180 degrees counterclockwise on the right side" This formula is mainly used to make side edges.

1. Spelling cross: f(rur'u')f'

The top surface may be a piece, a corner or a word three situations, a piece can be placed arbitrarily, the corner needs to be rotated to the upper left corner, a word to be placed horizontally, a piece of the use of the formula will become a corner, the corner of the use of the formula to change a word, a word using the formula to become a cross.

2. Flip the whole color: r'u2rur'ur/ru'2r'u'ru'r'(Mirror formula, just remember one). The pattern formed after the cross in the previous step is not only the above two situations, if it is not a 4+1 "small fish picture", it can be rotated into a small fish figure by using a formula.

The technique of Rubik's Cube restoration requires placing the white middle block at the top, and then turning to the top layer to return the top edge to the top edge, and press F'u'f's mantra for bottom corner homing, press (uru'r')(u'f'UF) to carry out the centering of the prism, press F(SRUR'u')f'Carry out the apex return position, and finally the top corner face, homing and apex return according to the formula.

The Rubik's cube can be represented by F, B, L, R, U, D, M on the front and back, left and right, and the upper bottom can be represented by F, B, L, R, U, D, M, R represents the right side of the clockwise rotation of 90°, and the top edge can be returned to the top of the center, so that the white edge block is connected with the middle block of the same color on the other side.

The third-order Rubik's Cube reduction formula** is as follows:First, the top layer makes a cross of the same color: r' u2 r u r' u r<>

The second is to homing the corner blocks of the same color: r' u'r u'r' u2 r<>

The third is to homing the middle edges: 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, to bring the top edge into place: xur'u'lur u'r<>

Sixth, to bring the corner blocks of the top layer into 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)

The third-order Rubik's Cube third-order reduction formula is: lower right, upper left, front left, upper left, front right, upper right, upper right, upper right, upper 180 degrees, upper right.

When restoring the third-order Rubik's Cube, the most important thing is to restore the last layer. Because the restoration of this layer requires the use of some special formulas and techniques to achieve the best results. One of the most commonly used reduction formulas is Bottom Right, Top Left, Front Left, Top Left, Front Right, Top Right.

The purpose of this formula is to reduce the last layer of the Rubik's Cube to a cross shape, laying the foundation for subsequent reductions.

When using this formula, you need to turn the Rubik's cube to the side that needs to be restored face up, find a small piece of the same color as the top one in the lower right corner of this side, and turn this small piece to the bottom right corner.

Follow the order of the formula until you get a cross. Next, you need to carry out some special operations according to the specific situation of the Rubik's Cube to finally complete the restoration of the entire Rubik's Cube.

The mantra of the third-order Rubik's Cube

The formula of the third-order Rubik's Cube is the return of the bottom edge, the return of the bottom corner, the return of the second layer of edges, the top edge position, the top angle position, the top edge return, the top corner return, etc., when restoring, according to the formula of the restoration, the Rubik's Cube is more used in the restoration of the seven-step reduction method.

In addition to this formula, there is another very important reduction formula, which is lower right, upper right, upper right, upper right, lower right, upper 180 degrees, upper right. What this formula does is restore the corner blocks of the last layer of the Rubik's Cube to the correct position. When the user is using this formula:

You need to turn the cube to the side you want to restore face up, find a corner block in the lower right corner of this side, and turn the corner block to the bottom right corner. Then follow the order of the formula in turn until all the corner blocks are restored to the correct position.

Third-order Rubik's Cube reduction formula: r'uf'u'、r'd'rd x,3or5,r u r',(ru r'u'),ru r'u')3,u' l' u l u f u' f',u r u' r' u' f' u f,f(r u r' u')f'，(r u r' u'2 and (r u r' u'5, and r2 d2 r' u' r d2 r' u r'，r u', l' u' l u2 r u' r',u'l' u l。where r represents the right layer 90° clockwise; L represents 90° clockwise for the left layer, U represents 90° clockwise for the top layer, D represents 90° clockwise for the bottom layer, F represents 90° clockwise for the front layer, and B represents 90° clockwise for the rear layer.

Band'represents 90° counterclockwise; Band 2 represents rotation 180°.

When the third-order Rubik's cube is restored, it is generally restored according to the seven-step reduction method. The order of the seven-step reduction is the top cross, the bottom edge homing, the bottom corner homing, the edge block homing, the apex polygon position, the apex polygonal position, the apical angular homing, and the apex corner homing. The Rubik's Cube rotates according to the formula when restoring, and the more basic Rubik's Cube is the third-order Rubik's Cube, and the third-order Rubik's Cube is the more basic Rubik's Cube in the Rubik's Cube, and many high-level Rubik's Cube and special Rubik's Cube are restored on the basis of the reduction method of the third-order Rubik's Cube.

Third-order Rubik's Cube Reduction Formula:
