The method presented here divides the cube into layers and you can solve each layer applying a given algorithm not messing up the pieces already in place. You can find a separate page for each one of the seven stages if the description on this page needs further explanation and examples.
Watch the cube being solved layer-by-layer with this method:
It fixes the white edges, corners then flips the cube to solve the second layer and finally completes the yellow face.

If you get stuck or you don't understand something, the online Rubik's Cube solver program will help you quickly fix your puzzle. All you have to do is input your scramble and the program will calculate the steps leading to the solution.
Use this stage to familiarize yourself with the puzzle and see how far you can get without help. This step is relatively intuitive because there are no solved pieces to watch out for. Just practice and don't give up easily. Try move the white edges to their places not messing up the ones already fixed.
In this step we have to arrange the white corner pieces to finish the first face. If you are very persistent and you managed to do the white cross without help then you can try to do this one as well. If you don't have patience I'll give you some clue.
Twist the bottom layer so that one of the white corners is directly under the spot where it's supposed to go on the top layer. Now, do one of the three algorithms according to the orientation of the piece, aka. in which direction the white sticker is facing. If the white corner piece is where it belongs but turned wrong then first you have to pop it out.
Until this point the procedure was pretty straight forward but from now on we have to use algorithms. We can forget the completed white face so let's turn the cube upside down to focus on the unsolved side.
In this step we are completing the first two layers (F2L). There are two symmetric algorithms we have to use in this step. They're called the Right and Left algorithms. These algorithms insert the Up-Front edge piece from the top layer to the middle layer while not messing up the solved white face.
If none of the pieces in the top layer are already lined up like in the images below, then turn the top layer until one of the edge pieces in the top layer matches one of the images below. Then follow the matching algorithm for that orientation.
After making the yellow cross on the top of the cube you have to put the yellow edge pieces on their final places to match the colors of the side center pieces. Switch the front and left yellow edges with the following algorithm:
All pieces are on their right places you just have to orient the yellow corners to finish the puzzle. This proved to be the most confusing step so read the instructions and follow the steps carefully.
Turn the top layer only to move another unsolved yellow piece to the front-right-top corner of the cube and do the same R' D' R D again until this specific piece is ok. Be careful not to move the two bottom layers between the algorithms and never rotate the whole cube!
Bruh I learned it in 2 days and took me a week to get sub 50 and for the record im not saying that im smart cause I also taught 3 of my friends how to solve and thy all were pros in under a week I even taught a 9 yr girl how to solve it and she got it on 5 days.
I found my old cube in storage, gave it a go to search tutorials on youtube, Clickbait title, Learn To Solve Rubiks Cube In 10 Minutes! I was able to solve a cube under 5 minutes after about 20 minutes of the tutorial. I then train and practice somewhat often, I purchased a high quality GAN cube for $60 and eventually averaged 45 seconds to solve, I now am starting a collection of every type of cube from 11 to 55, pyraminx, and gear puzzle. If you put in the effort, you will learn.
In start i used to get frustrated when solving rubic cube even if i was copying the tutorial on you tube. But one the day i decided i should really do it when i saw 9 years old boy can do it in 70 seconds. Then i watched a tutorial and it took me an hour to solve the rubic cube and now i have remembered all the algorithms and can do without watching any tutorial. I am so happy. By the way i am 39 years old man.

What started as an ergonomic experiment by Hungarian Architect Erno Rubik, soon became one of the most popular mainstream puzzles. With almost half a billion cubes being sold, chances are you came across one and were amazed (& terrified) with it.
After a decade of running away from the cube, I finally added it to my resolutions list for the year of 2020. However unlike other items on my list, I dreaded getting started on this one and postponed doing it till as late as November 2020. During my block leave for the year, I finally got my hands on solving the cube. It took me about 4 hours (and multiple anxiety attacks) to solve it for the first time and almost a weeks time to take my average time down to just under 3 minutes.
At first it looks difficult. Then you attempt solving it and it now looks almost impossible. You keep up the efforts and now it looks somewhat plausible. And then you finally solve it. And now it feels as easy as riding a bicycle.
In the summer of 2015, I went to my first Maker Faire, in Tokyo, Japan. Afterward, I could only think about the challenge of making something. It moved me so much that I left the company where I worked as a programmer for 16 years and became a full-time maker.
My cube, when scrambled and placed on a desk, starts turning its faces to solve itself. It recognizes its color arrangement and solves from its current state, rather than reversing scrambled movements. It works independently without the need for an external computer or cameras, and can solve itself in about 30 seconds, no matter how scrambled.
Generally, a machine that solves Rubikʼs Cube with robot arms uses cameras or color sensors. I came up with the idea of using rotary position sensors. I programmed the microcontroller so that the rotary position sensor would detect when the face was turned by hands and the color arrangement data in the memory would change.
I decided to disassemble the servos to access the gears and motors and use just them. I spent a lot of time considering their arrangement (Figure L). Then I made a 13-piece gearbox and put the servo gears and motors in it (Figure M).
I first printed all 26 pieces with a 3D printer to a slightly larger size (Figure R). I filed them little by little over a month with precision needle files and sandpapers. During that time, I found the proper width of the gap and proper strength of the spring by repeatedly assembling them (Figure S).
Currently I am studying the Schreier-Sims algorithm. To gain a deeper understanding, I am trying to look into applications of this algorithm, among which its use for solving the Rubik's Cube is perhaps the most famous.
However, it seems that there is not a complete, comprehensive algorithm that uses the Schreier-Sims method to solve the Rubik's Cube. Instead, there are only scattered, fragmentary methods, most of which date back over a decade and do not entirely align with the overall framework of the Schreier-Sims algorithm. Does this mean the problem has not been fully resolved?
Is there any simple introduction of using the Schreier-Sims method to solve the Rubik's Cube? If such a guide is not available, is there any examples where the Schreier-Sims algorithm is applied to similar problems? Thanks a lot.
The Schreier-Sims algorithm computes what is known as a strong generating set of the group, which starts with the given generating set and appends new strong generators as words in the existing strong generators. Having done that it can express arbitrary group elements as words in the strong generators very quickly. You could then use the definitions of the new strong generators to express the element as a word in the original six generators (which is known technically as evaluating a straight line program), but the resulting expanded words will be very long in general.
I tried doing this with ten random elements of the Rubik cube group in Magma. The average length of their words in the 27 strong generators was 33, whereas the average length of the expanded words was about 13 million, which is indeed not very efficient.
The purpose of this guide is to help you achieve your first blindfolded solve. There are multiple methods to choose from when solving a cube blindfolded. For this guide, we will use the M2 method on the edges and the Old Pochmann method on the corners.
The first step is about making a decision and sticking with it. You will need to decide how you will hold your cube for blindfolded solves. It does not matter which way you hold it, it just always needs to be consistent.
I always hold my cube with the yellow center piece facing up and the red center piece facing me. When I do this, I know that green is on the right, blue on the left, orange in the back, and white on the bottom.
I chose this orientation because it is the orientation I use for regular solves when solving the white cross on the bottom. Make this choice now and take some time to get familiar with where the colors go if this is not natural already.
Mix up the cube and practice envisioning where each piece belongs based on your orientation. For example, when I see the green and red edge piece, I know immediately that it goes on the front right edge.
The next big decision to make for blindfolded cubing is a lettering scheme. The goal here is to associate every sticker on the cube with a letter of the alphabet. Some people do not rely on letters, but I believe using a solid lettering scheme makes the memorization process much easier.
