Ask the third order Rubik s Cube master, I m a rookie

Make sure the quality of your Rubik's Cube first....Those 10 Rubik's cubes will definitely not improve the score. The closure of the national C is good. After 50s, you can start practicing CFOP, go to the Rubik's Cube station** and print out the formula of a CFOP.

It is recommended to memorize the commonly used OLL first, because this formula is the simplest and can save a lot of steps. You can read PLL halfway through the memorization, which is also commonly used. If the third layer and the top surface can be done in one step, then 35s is no problem.

Well, I'll be playing in an hour and a half.

1. Buy a better Rubik's Cube, and you can consider the national armor seal three before 30 seconds, and then you can use the first five or wild geese.

3. Learn FSC fingering to make the technique smooth.

4. The most important thing is to practice a lot.

Some people suggest that you don't mess with people's advice, it's good to enter 50 seconds, but you don't need to change the Rubik's cube, who said that 10 yuan will definitely not be able to improve? As long as the lubrication is appropriate, it can also rotate rapidly, of course, its quality is indeed not very good, it is easier to wear and tear, if you have the conditions, you can buy one, between your level, don't use the fault tolerance, A two Guhong or something, in the future, you can consider sealing three, of course, the best beginner practice technique is a one, but since you have learned, Feng San can also be, buy don't go to the Rubik's Cube station, indeed, his is true, but expensive to death, and I doubt that his reputation is also brushed out, I bought it from the big cigarette butt store at the time.,I'm sure you must know him.,The national armor is named after him.,Senior demon friend.,Very good.,It's cheaper than a small station.,But there's one point.,Stickers have to be pasted by yourself.。 As for the technique, go to the Rubik's Cube and go to the gan technique, this is the most famous, but I'm a mobile phone now, I can't give it to you, you can just search for it.

The third-order Rubik's Cube tutorial is as follows:

The bottom angle homing formula is (r u r'）、f'u'f）。

The formula for the homing of the middle edge is (u' f' u f）、（u r u' r'），u r u' r'）、u' f' u f）。

The formula for apical surface homing is f(r u r' u'）f'。

The formula for the homing of the apical angle face is r' u2 r u r' u r、u' r u'u' r' u' r u' r'。

The formula for apical prismatic homing is (r u' r）（u r u r）（u' r' u' r2）。

3rd Rubik's Cube Strategy:

When the 3rd order Rubik's Cube is spelled, it is necessary to spell out a top-level cross first, and then put the entire surface together, and then spell the other four corner blocks, and pay attention to the colors when fighting one by one.

Then the middle side block is homed, turn the white side downward, find the red and green edge blocks, and turn the Rubik's Cube according to the formula to make the side blocks return to position.

Adjust the top layer of the side block upwards to make a yellow cross, the top layer does not appear yellow cross, and it can be repeated according to the formula.

Adjust the yellow corners of the Rubik's Cube to the cross, position the yellow blocks at the four corners, and adjust the color blocks on the sides to the corresponding positions.

1. The bottom cross.

To complete all 12 edges, the first step is to put together a cross and complete the first four edges. And make the color of the cross uniform with the color of the center block around it. The cross can be groped for itself.

It doesn't take too difficult skills to complete the cross alone. As long as you have a certain amount of spatial imagination and logical thinking ability, plus a certain amount of time to study, there is no problem in completing the cross independently.

2. A middle layer of edges.

After completing the cross, the next step is to flip the entire cube so that the yellow side is facing up, and complete the edges of the middle layer. The edges of the second layer can also be derived on their own.

3. Top-level cross.

If the last edge does not appear in the middle layer, then there must be a yellowish edge inside the slot. So let's go to the top layer (r) first, and then dodge, (you or u.)'or u2) to return the scrambled edges (r'）。

4. A top-layer prism.

The most basic situation we have to deal with is that the back has been restored and the front 3 edges need to be rotated. Here is the formula first, and the author will give an analysis later. It can be a bit tricky to understand this step at first. But it is still advisable to look at the derivation formula.

Clockwise three rotations: r'u'ru'r'u2r。This is the small fish formula used in the layer. The formula for counterclockwise substitution is symmetrical with its mirror image: lul'ulu2l'。

5. Top-layer corner block - replacement.

Finally came to the corner block. Let's take a corner block as an example. Rotate the top layer (remember to turn only the top layer) so that the corner block is below the target position.

Now let's forget about everything except the top layer and this corner block. Let's abstract the problem and see what to do with this corner if it were a one-sided piece. The old routine is to move this corner block to its target position, then dodge it, leave a slot for the top edge to come back, and finally return the block to its position.
