Find the advanced Rubik s Cube reduction formula, restore the formula of the Rubik s Cube

Landlord. First of all, your speed is not suitable for memorizing CFOP. It is best to stabilize the score at about 40s before memorizing. 90s is still too slow.

I won't give you the formula for CFOP here, because there are too many formulas. I'll give you some tips to speed it up.

It's mostly practice. I'm going to give you some tips for the landlord here.

1: The cross is directly established correctly.

2: In the two steps of the bottom layer and the second layer, it is not necessary to first the bottom layer and then the second layer. For example, I used white as the bottom and put down the white, red, and blue corners after building the cross.

At this time, the red and blue edges are observed, and you can lower this edge first and then the other corners. Doing so saves time in observation.

3: If the landlord's Rubik's Cube performance is good, then you can change to a less fault-tolerant Rubik's Cube to practice, and you can practice accurate fingering. So as far as the Rubik's Cube is concerned, I don't agree with the view upstairs.

4: Don't speed up your hands, practice with slow twisting. When the average of the Rubik's Cube is less than 15s, the main factors that affect the speed are coherence, observation, and formula, and after entering 15s, it has a greater relationship with hand speed.

5: Memorize some simple, useful oll, such as the seven cross case, and frur'u'f'(Positive, Right, Ascending, Right, Ascending, Ascending, Positive), frur'u'f'。(The front two layers are straight, the right is straight, the upper is straight, the right is reversed, the upper is reversed, and the front two layers are reversed.)

6: Practice the high-level Rubik's Cube, which has been proven to be effective for third-order speed-up. (Available or unavailable).

7: Exchange experiences with friends.

8: This is a supplement to 1, that is, when the Rubik's Cube is played, there is 15s of observation time, what is it used for in 15s? To observe the cross, you first need to find the center and edge of the target cross, and then consider how to rotate it so that the steps to create the correct cross are the least or the smoothest.

If there are slightly more steps than the least steps, the smoothest step is preferred. ）

That's basically my experience of playing Rubik's Cube. In addition, the layer-first method has great advantages in observing the first and second layers. Please take advantage of this.

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

Prepare the material: Rubik's Cube.

1. Make a cross of the same color on the bottom surface.

2. T1, front + up + front + up + front + up - front - front - up - front -.

3. T2, right-up-right-up-right-up+right+up+right+right+.

4. Draw a cross on the item layer.

5, T3, right-up-front-up+front+right+.

6. Press T3 to make one side to get an L-shape composed of three pieces.

7. Turn to the upper left corner to become an inverted L-shape.

8. Do T3 again, you can get a slot.

9. Put the word shape vertically, and do T3 to get an item layer cross.

10. Spell the third layer of items.

11、t4，r-u-r+u-r-(u-)2r+u-r-(u-)2。

12、t5，f+u+f-u+f+(u+)2f-。

13. When there are three variegated corner blocks on the top layer, use T4 or T5.

14. When the corner blocks of the third layer are arranged counterclockwise, use T4.

15. Before use, ensure that the corner block in the upper left corner of the top layer is the correct color block.

16. Find a corner block of the same color as the top cross on the side of the third layer.

17. Use T4 once to appear that there is a color block on the item surface.

18. Find a corner block of the same color as the top cross on the side of the third layer.

19. Let the color block with the same color as the neck face go backwards.

20. T4 and T5 can be used below.

21, t7, counterclockwise, r+u-r+u+r+u+r+u-r-u-r-r2.

22, t8, clockwise, r2u+r+u+r-u-r-u-r-u+r-u+r-.

Rubik's Cube Reduction Formula.

Hello dear, the formula for the reduction of the Rubik's Cube is as follows:

1. Make a white cross. Clause.

Second, the first layer of formulas: right, up, right, up, right, right, up, up, right. Clause.

3. The second layer of formulas: right shun, upper shun, right shun, upper shun, right reverse of the weighing cover, upper inverse, right inverse, upper inverse, right inverse. Clause.

Fourth, the second layer of the formula is reversed: right inverse, upward inverse, right inverse, upward inverse, right transport slag side quiet inverse, upward shun, right shun, right shun, right shun. Clause.

Fifth, the third level of formula: right, up, right, up, right, right, up, up, right.

The full set of formulas of the Rubik's Cube is as follows: 1. Formula: small fish formula: up, left, bottom, left, up, left, left, left,

2. T word formula: up, right, up, left, up, left, up, right, up, up. 3. Middle-level formula:

Down, up, left, up, right, down, down, up, right, up, left, down. 4. Prism formula: up, left, or right, down, down, down, up, down, up, right, down, right, up, down, up, right, up, down, up, right, down, down, up, right, down, down, up, right, down, down, right, down

To play the Rubik's Cube, you must first set the center of the Rubik's Cube, choose a favorite color among the 6 colors, and then position and orient the 4 edge squares on the plane of the center square with this color, that is, the top edge. The goal is to position and orient the blocks that belong to the 4 edges of the top plane. The 4 top edge squares are placed and oriented one by one.

The final step of the third-order Rubik's Cube reverts the formula: r+, u-, r+, u+, r+, r+, u-, r-, r-.

The last step needs to be restored well, if the previous step is not restored, then the Rubik's Cube can not be restored, at this time the formula of the previous step should be repeated many times, after the previous step is restored, the restored side will be treated as the B side, and the Rubik's Cube can be restored after several times.

The last formula of the third-order Rubik's Cube is: the Rubik's Cube is held on the blue, the front is yellow, and it is done (right inverse, upper straight, right inverse, upper inverse, right inverse, upper inverse, right inverse, upper shun, right shun, right shun, right shun 180).

Layer code: Each layer of the Rubik's Cube is referred to by the initials of the English brother's skin. r(right), l (left), u(up), d(down), f(front), and b(back) refer to the right, left, top (top), bottom (bottom), front (front), and back (back) layers, respectively.

Rotation direction: rotate 90° clockwise, and write the code of each layer directly; Rotate 90° counterclockwise, and suffix [in the code of each layer'] or [i]; The mascot rotates 180°, with the code suffix or [2'] on each layer (the default is 180° clockwise); Rotate two layers, then use the code of each layer in lowercase or add a [w] after it.
