What should I do if I can t understand the third order Rubik s Cube restoration formula?

First of all, you need to understand the Rubik's Cube terminology:

f (front) is the meaning of the front, clockwise direction, f'It is to turn in a counterclockwise direction in front.

b(behind) is the meaning of the latter, ditto, b'It's the back. Ditto.

r (rgiht) means right-hand side, pay attention here, the right hand should be turned up, r'It's counterclockwise, that is, turning down on the right-hand side.

The meaning of l (left) is to turn to the left-hand side, l'It's just going up.

U (up) means top, turn to your left-hand side, u'Just turn to your right-hand side.

d(down) is the meaning of the underside, turn in the direction of your right-hand side, d'It's just going to your left-hand side.

f2 means 180 degrees ahead.

B2 back

r2 to the right

l2 to the left

u2 top surface

d2 Bottom Same as above...

The first layer,That's the base,Bottom,Twist the cross (whatever color you choose,It's OK,But when I solve it,I like white as the bottom,Because it's easier to distinguish),And then the color (that is,When you make white into a cross,Its corresponding color,Blue,Green。。 Wait for the center color to be connected together (except for yellow)), and then just fill in the 4 corners of white. The formula for the second and third layers - the second layer, the first one, if you want to fill in the left one, is u',l',u,l,u,f,u',f'。

Fill in the words on the right are u, r, u',r',u',f',u,f, by the way, I will also give you a little bit of the formula of the third layer, a word, a small l shape (the L word is reversed), a cross, all use this formula -r',u',f',u,f,r and then there is a little more cross, here you have to pay attention, a little more cross, the more point should be towards yourself, if there is a point on the left hand side (the idea * left hand side has a little bit of meaning, that point is on the third layer, but not at the top, but facing you, this point should be remembered!). That's what formula l is',u',l,u',l',u',u',l, if there is a point on the right-hand side, use this formula -r, u, r',u,r,u,u,r'Now that the top surface is finished, we have reached the angle, and the formula for the angle (relatively long) -r, u, u, r',u,u,l',u,r',u', l angle is good, and finally the remaining edge - you have to see if it is clockwise or counterclockwise, clockwise is to turn to your left hand - f2, u, l, r',f2,l',r,u counterclockwise is to turn -f2,u to your right',l,r',f2,l',r,u'Okay, that's the formula for the second and third layers, when you can enter the first method for 2 minutes, you can learn CFOP, I hope you can reply to the six sides, if there is anything you don't understand, feel free to ask me, I can also be regarded as a communication, hehe, my name is the last samurai.

f means front, b means back, l means left, r right, d below, u, and the top is represented by letters clockwise, such as u means that the upper layer is rotated 90 degrees clockwise.

Counterclockwise is denoted by a skimm, as in u'Indicates that the upper layer is rotated 90 degrees counterclockwise.

180 degrees is represented by 2, e.g. u2 means that the upper layer rotates 180 degrees clockwise, u'2 indicates that the upper layer is rotated 180 degrees counterclockwise.

The corresponding lowercase letters f, b, l, r, u, and d represent two layers of rotation.

x (the whole cube rotates in the direction of r), y (the whole cube rotates in the direction of u), z (the whole cube rotates in the direction of f).

After that, there are four edges in the second layer, and you only need to memorize two formulas: the case where the top color is equal to the color on the right and the case where the top color is equal to the previous color, and these two formulas are uru'r'u'f'uf and.

u'f'ufuru'r'The letters are abbreviated in English One more is counterclockwise rotation Without adding is clockwise u=up r=right f=frount Alas, you can't play the word You still go to the Rubik's Cube station to see But it is not recommended that you learn the layer first method I have taught many people the layer first method I regret dying Wrong people Or use the CFOP method Basically, you can improve by 30 seconds by learning one step and then learn another step to improve by 30 seconds Finally, it is very easy to enter 30 seconds Come on.

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.

<> answer: Take one side of one of the colors to yourself (e.g. red) and the yellow side 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 Gong Fan Duo both Yi Huan forehead only touch the round fight 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 is usually a cube in shape, made of elastic hard-cavity 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.

The formula for the reduction of the Rubik's Cube is as follows:

1. First, select a face to build a grip cross, and then align the color of the center block on the four sides of the letter with the adjacent color of the cross.

2. Return the bottom layer according to the way of up, left, bottom and right, if the homing is correct, the side has a layer of spelling.

3. Then align the center block with the assembled layer, and put together the middle layer of the side according to the formula.

4. Assemble the cross on the top floor, but be careful not to disturb the parts that have been put together in front, and then put together the top surface according to the formula.

5. Align the color in the middle of the third layer on the side with the color of the center block, and put together the third layer of the Rubik's Cube according to the formula to complete the restoration.
