Most beginners choose the layer-first method, which is characterized by few formulas and easy understanding; Racing players usually use CFOP method, and they can restore the six sides of the Rubik's Cube within 30 seconds after proficiency. Here is a brief introduction to this method.
Introduction of Rubik's cube formula steps
The CFOP method is divided into four steps: cross->; F2L->； OLL->； phase-lock loop
Cross: It means to make a cross at the bottom.
F2l: (the first two layers) means to align the first two layers at the same time.
OLL: (Orienting the last layer) means uniform color, with the top facing up.
PLL: (positioning the last layer) means adjusting the order of the top layer (completing the whole Rubik's cube)
Step one, pass through the bottom frame.
1. When making a cross, remember four colors. You should also remember the corresponding color changes on adjacent faces. You must be able to look at one side and remember the color of the other.
2. Analyze the patterns after each interruption as much as possible. According to statistics, in 99% of cases, the cross can be completed in seven steps.
3. Twist the cross blindly so that it has no mistakes.
4. Gradually reduce the thinking time until you can twist the cross blindly within each observation time of 15 seconds.
5. It is very important to find the first group of F2L from the completion of the crossing, but even a very fast person can hardly complete this step without stopping.
6. Slow down the speed of making a cross and find the first pair of F2L at the same time.
7. Don't look ahead when making a cross, which forces you to slow down when making a cross, thus making your movements more coordinated when completing the transition from the cross to F2L.
8. Put the cross in a unique box. When the crossover is completed in this way, analyze its F2L trend.
Step 2: Complete the first two layers (F2L) with 4 1 case.
1. If you are just beginning to learn F2L, you should fully understand each formula and write down some similar formulas. This will not only help you remember F2L, but also help you in the future.
It will be of great benefit for you to know F2L intuitively during the application process.
2. Reduce the observation time. In addition, you should be able to recover the same case from all aspects.
3. Find the formula that suits you best, watch experts' videos on the Internet and see how they do F2L.
4. In F2L, one of the most important suggestions is to slow down and predict the future. If you are proficient in every formula, but if you have completed a set of F2L, you need time to find the next set.
Then your F2L level is far from being in place. Pre-judgment means that when doing the first group of F2L, the speed should be slower, so that you can have time to observe the trend of the next group of F2L and ensure that each group.
Seamless connection between F2L. The final state of the whole four groups of F2L should look like an action group. It should be less than 20 seconds (within 20 seconds).
Here is a good way to train your prediction ability. With a musical metronome, at the beginning, you can rotate the Rubik's cube at a speed of 2 steps per second. Maintain a speed of 2 steps per second.
It can keep your hands busy for a while. If the average is less than 20 seconds (less than 20 seconds), your goal is 3 steps per second. Rubik's cube is also very popular: the method is very good, and experts also listen to music before the game.
Find the feeling )
6. When you practice for a period of time, you can try to improve your speed while making predictions. It will make you feel uncomfortable at first. But gradually, you will like this rhythm.
Make accurate predictions.
7. It is very difficult to predict OLL, so you must take the time to judge OLL. So, after practicing everything very skillfully, play four groups of F2L at full speed to judge the formula of OL.
Step 3, top surface reduction (OLL)
1. For each case, learn to solve from two directions. For simple cases, learn to solve from any direction.
2. learn some COLL, and it will be very practical to encounter some cases.
3. Time is 57 OLL, the sooner the better.
4. Practice and judgment of zero delay PLL.
Step 4, top surface thinning (PLL)
1. All modes should be able to recover from at least two directions.
2. Some simple situations should be able to recover in all four directions.
Because of the last step in these CFOP, you should choose a good formula, so that you can press the timer by hand after restoring the Rubik's Cube.
4. Time to complete 2 1 PLL, the sooner the better. Find more PLL formulas online.
Summarize CFOP
1. If possible, videotape yourself and compare yourself with the master.
Communicate with experts more, and you will learn a lot from them.
3. Not only learning speed, but also learning Rubik's cube teaching, blind twisting and minimum steps.
4. Try to play in the presence of others (Rubik's cube is also popular: because you usually practice at home, you will definitely feel nervous when you show it to others)
Step 5 Participate in online discussions
6. Try to learn some other skills, maybe you can find more suitable methods and inspiration.
7. Remember a disturbing formula, and then restore the Rubik's Cube. In this way, you can compare the fluctuation of your grades under relaxation and pressure.
