What do all the letters in the Rubik's cube formula mean?

F = front face front B = back face back R = right face right face L = left face left face U = up face above D = down face below Take the markings in the table above as an example, F would mean the front is turned 90° clockwise, F' would mean the front is turned 90° counterclockwise, and R2 would mean the right side is turned 180°, and it's just so That's all. The Rubik's Cube is not a one-sided play, but a layer to complete then how to play six-sided it, the process is actually the first layer, the second layer, the third layer! It is simple to say, but each layer has to be rotated after some to form, and a little bit of fun can also be said like magic, when you complete a process, twist the other places will not affect your front of the completed layer, of course, there is a certain formula or called the password, a little bit of excitement, right? Let's take a look at how each layer is twisted. Layer 1 (if you already know this layer, skip to layer 2) This first layer is very important! You have the ability to complete one side, so to speak, and you have the ability to complete all six! It's just a matter of method. It won't hurt your brain cells too much. Of course, you may say, finish one side of my six-year-old nephew can also ah. The one side I'm talking about will hurt your brain cells a little bit. I'm asking you to complete the one side with a uniform color around it. Maybe you have played before without paying attention to this problem, but today you want to do "master" you have to play in this way, is not much harder? This way, the first assumption that you are now spelling a side of yellow, first randomly find a color spell, such as yellow and a middle color, and then look for a yellow and blue and a corner block of other colors (find a red oh) spell it out, and then look for a yellow and red center block and then spell it out, and then the same way a circle on the completion of it. If there is a piece of yellow that was already on top but is not the right color, replace it and find the right piece until you complete the circle. How's it going? Have you practiced one side of the row yet? Well look at the second layer Play: the second layer in order to see the map convenient, here must first talk about some of the English symbols, the international station is also used in this way to mark, so you learn these symbols if you see people foreigners can see how to twist the web page. We now assume that the Rubik's Cube is fixed then relative to us is divided into: Front (F), after (B), left (L), right (R), on (U), under (D) six sides Front = Front Back = Back Left = Left Right = Right Up = Above Down = Below which are all clockwise Turn a bit, that is, rotate the 90-degree angle If it is added with a single quote ', that means counterclockwise rotation of 90 degrees. If you add a single quotation mark ', that is to say 90 degrees counterclockwise rotation If you add a 2, that is to say two turns, that is to say 180 degrees, in fact, after turning 180 degrees, either clockwise 180 or counterclockwise 180 degrees of the results are the same. So sometimes it depends on the direction of your hand to choose whether to turn 180 degrees clockwise or counterclockwise. If you turn the cube over after completing a row, so that one side is on the bottom, and twist the colors to align with the center. You will find that there are about two such cases: Solution 1: U R U' R' U' F' U F Solution 2: (in fact, the same as above, but in the opposite direction) U' L' U L U F U' F' Principle of the mnemonic: one step away from the goal, remove the bottom one, and then put back the bottom one. But if you encounter a situation like this you can just use one of the above methods to change it out and then turn it into the above shape again, of course, if you are a very willing to learn, you can memorize the following longer formula directly to the opposite solution: F2 U2 R' F2 R U2 F U' FOK, right? Then we will enter the third level of the third level will generally have the following three major cases: our current goal is: cross! We refer to as, point, line, fold The solution you just need to memorize a formula! R' U' F' U F R If the cross has appeared, we now first to adjust it to the center of the alignment of the color, of course, not necessarily once can be successful, may also need to change the position of the formula is very easy to change the position of the formula is to the left and the front of the prongs of the mutual exchange of the RUR 'U R U' U' R 'very good, your cross has four sides The next step is to change the corners, which is done with another formula L'RUR'U'LURU'R' L'RU'LUR'U'L'UL Okay, now comes the most exciting moment of all, the moment of finalization! Please keep your head cool! First, L'RUR'U'LURU'R' the whole cube to a U, then L'RU'LUR'U'L'UL If it's not done yet? L'RUR'U'LURU'R' Turn the whole Rubik's Cube into a U, and then L'RU'LUR'U'L'UL This time it will work!

★ x: (the whole cube turns in the direction of R), x': (the whole cube turns in the direction of R)

y: (the whole cube turns in the direction of U), y': (the whole cube turns in the direction of U)

z: (the whole cube turns in the direction of F), z': (the whole cube turns in the direction of F')

This is the first time that you have to turn a U in the cube.
