How the Rubik s Cube compresses the speed to less than a minute.

f- turn clockwise in front and b- turn clockwise in rear.

l - turn clockwise on the left side r - turn clockwise on the right side.

U - Clockwise above D- Clockwise below (if added'for counterclockwise rotation).

1.Start by turning a cross on one side of the same color as the center block on the side (it's easy to try it yourself).

2.Place the cross on top, find the corner block from the bottom layer to be homed, make it below the position you want to homing, press R'd'Rotate the rd 1, 3 or 5 times until the corners are in place, and then use the same method to return the other corners to their positions.

3.Inverting the Rubik's Cube, the face has been put together below, the top layer is rotated to one side is an inverted T, and the color of the top layer is the color of the small T on the left or right side upside down. If it is the color of the small T upside down on the left, press U'f'ufuru'r'Turn the Rubik's Cube; If it is the color of the small T upside down on the right, press URU'r'u'f'UF rotates the Rubik's Cube so that the piece just now falls between the two small T's, and then uses the same method to return the other corner pieces to their positions.

4.Press frur'u'f'Turning the Rubik's Cube 1 or 2 times will cause the top surface to appear as a cross.

5.Turn the top layer so that the color of the piece in the middle of the front upper layer is the same as the color of the lower two layers, press rur'uruur'Turn the cube 1 or 2 times to shape the surroundings into a front shape.

6.Find the corner block of the position pair (just the position pair) and press URU'l'ur'u'l Turn the Rubik's Cube 1 or 2 times so that the positions of the four corner blocks are correct.

7.Is a corner block in the wrong position in the upper right front corner, press R'd'rd rotate the Rubik's Cube 2 or 4 times, the color of the upper right front corner is also correct, turn the top layer, it is another piece to the position of the corner block that has just been restored, and repeat the steps just now. Repeat the steps above, and the imitation will be completed.

Do you restore the first two layers together, or do you want to restore the first layer first and then the second layer? The former is CFOP, the mainstream third-order advanced gameplay, and the latter is a more basic layer-first method. The speed of CFOP will be greatly improved after practice, but it takes a long time to practice, as little as two or three months, and as many as a few years.

Now the mainstream racing methods are CFOP, in view of the disadvantages of the layer-first method, the landlord can improve the amount of his formula, specialize in OLL and PLL, and then learn CFOP when going further, which has high requirements for observation.

That's the kind of thing I know, and it's speed.

If you want to change to a smoother Rubik's Cube, the national armor and the holy hand are good, and you have to memorize the formula, practice more, and you don't need the formula if you have a feel.

In the first step, the landlord will change the Rubik's Cube. For Guo C, the fault tolerance of Guo C is average, which is suitable for practicing the accuracy of the technique. At first, it will feel very stuck, but if you stick to it, your hand will become very precise and smooth.

The second step is to memorize the formula. Again, I can't eat hot tofu in a hurry. CFOP is a must-read Bible for novices.

But CFOP isn't easy to get started with. To learn CFOP, you have to memorize a large number of formulas, among which the obvious effect of memorizing is the OLL and PLL formulas. The PLL formula recommends memorizing the angle adjustment formula first, and then memorizing the whole formula.

The OL formula only needs to be memorized in the case of a full cross and a point. Memorize 5-10 formulas a day, practice one formula repeatedly, and form muscle memory, so that you only need to observe and not think about the steps in the restoration process.

The third step is to practice observation.

1. About the Rubik's Cube: Choose the right one for yourself, ask for some good brands, I use the holy hand, and pay attention to the maintenance of the Rubik's Cube, moisturize the oil in a timely manner, and avoid bumps and bumps.

2. Self: Don't use your wrist to turn the Rubik's Cube, but use your fingers, you can practice the flexibility of your fingers.

Secondly, memorizing the formula, if you get started, you can be the most advanced CFOP, which may be a bit much, but it works very well.

In fact, even if you don't memorize the CFOP formula for three minutes, there is a lot of room for improvement, basically as long as you practice more, you can still do it for one minute and thirty seconds.
