Advanced Method. This is full CFOP (or Fridrich) method. 'CFOP' refers to the steps involved - Cross, F2L, OLL and PLL. This involves remembering a lot. It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method. This method is named after its creator, Jessica Fridrich. There are many different methods for solving the Rubik's cube. .. the advanced method, check out Dan Knights' advanced solution and Jessica Fridrich's LL.

looked at me frawning and said with his mouth half open: "Yeah, so what's your system?" I answered with a big smile: "I use the Fridrich method. This advanced technique developed by Jessica Fridrich divides the puzzle into layers and you have to solve the cube layer by layer using algorithms in each. Algorithms of the 2nd part to orientate the right upper corner (well positioned). This method is called Fridrich Method, and also CFOP, because of the four.

Fridrich's website offered a vast wealth of information for those entering the sport, including a full description of CFOP with complete lists of algorithms. As a result, many who learned from her website began to call this method the "Fridrich Method," which explains the common use of the term today. Several high-profile cubers have long disputed this terminology; Ron van Bruchem , famously, has publicly written that he will never call CFOP the "Fridrich Method. The term "CFOP" has since seen increasing usage compared to back then, also in part motivated by efforts to standardize terminology in method classification, and is now seen, commonly, as "Fridrich Method. In particular, it combines some steps of the said method into one by using many more algorithms. Here, we outline pure CFOP without any additional trick.

First we will turn the white corner so that it is not white on top anymore and then solve it with one of the formulas presented above. Every time you solve a pair, you are actually using the empty slot of that same pair.

If you don't, you may break other pairs that have been already built before. Before letting you play with your Rubik's cube, I would still like to teach you a couple of tips. Most of the time, what slows you down is your inspection and your thinking. So there is no need of turning the faces as fast as possible. Take your time and try to anticipate. Secondly, try to minimize the number of times you flip the whole cube during the resolution. Flipping the cube is the time when no move can be performed.

As everything changes when rotating the cube, all your inspection will be hard to transpose.

It has to be maximum once per pair, ideally just once or twice during the whole solve of the F2L. Also remember that you have two hands and the left hand should not only be used to hold the cube.

Have a look at the following case:. You may be tempted to solve this case with your right hand.

But doing it with your left hand will be quicker! With a bit of practice, you left and right hands can solve cases equally as fast. Not turning the cube on this special case saves you about seconds. If you are about to turn the cube, always make sure that you put the pair you are solving in the back.

Because if everything that is solved is in the back, then it is much easier to find what to solve next. Y ou would have a full visibility on all the unsolved pairs. Vision and thinking should be much faster too.

With a bit of practice on all the cases, you should get closer to 10 seconds first two layers. That is a great first goal and will help you to solve the Rubik's cube under 20 seconds.

Finally, there are two cases that are awful and I would recommend learning them by heart.

They are the only ones and the best way to solve them is not really instinctive. Here they are:. Now you have everything to find the best F2L algorithms using Fridrich method. The algorithms you will find will make sense and therefore will be easy to learn and to perform fast.

In the Fridrich method, the last layer is solved differently from the beginners method. It is the first step to the full Fridrich method, used by speedcubers. I will show you the orientation of the last layer in two steps.

First, we will see how to orient the edges and then the corners. In a last step, we will see how to orient both at the same time. It is of course quicker but also requires to learn a lot of formulas. Fridrich method is also called CFOP. To know it fully there are about 80 algorithms to learn and that is why I am going to first introduce an intermediary method. Orienting the last layer means putting all the yellow stickers on top. To do that we will need to flip the corners and the edges.

For the edges orientation, you should already know all the cases. I taught them in the page of the tips for solving the Rubik's cube. Nothing new on this step. Determining which case to use is very easy. You just need to count how many corners are not yellow on top. This should be immediate. But to correctly orient the corners, there are 7 different cases.

Either 2, 3 or 4 corners are incorrectly oriented. The formulas can seem a bit long but they are quite easy to learn. They also can be performed very quickly. If you have 0 corner to orient then you can directly move on to the next step. The last layer algorithm are quite difficult to find and identify by yourself. The most efficient here is to learn them by heart. I would recommend you to start with the formulas that orient 3 corners , because they are easy and you know them already.

Then then ones with two corners to orient and finished with the last two. Here are the magic algorithms:. You already know the two formulas. They were used the one after the other in the step 7 of the beginners method. But we are going to use either the one or the other depending on the case.

Here is what it looks like with the animations:.

Right hand: Left hand: Three different cases can happen here. Or the two corners are next to each other and the yellow is on the side. Or the two corners are next to each other and the yellows are not on the same side. Here there are two different cases. Either the corners are symmetric: Or they are not symmetric: In total, there are 57 OLLs.

Here, we outline pure CFOP without any additional trick. Also, the cube is commonly solved with the white side on top for the cross, yellow on the bottom for the cross, and opposite for the other steps. However, it is NOT required. Cross Make a cross on one side by solving all edges of a given face. A Make sure to align the edges with the second-layer centers.

It is recommended that you solve the cross on the bottom, left, right or back face and that you become familiar doing the cross with all colors; not just one. Each slot is filled by inserting a corner and its corresponding edge simultaneously. Most of the 41 cases have reasonable intuitive solutions.

The completion of this step leaves one with just the last layer, typically placed on top. The whole cross solving should be planned during the 15 seconds of inspection, before starting the resolution.

Once you are at that level, you should be able to solve every cross in under 1. To improve on the cross, my advice is to solve it blindfolded.

During pre-inspection, take more than 15 seconds. Look at your Rubik's cube and try to see the optimal solution for solving the cross. At first you will only be capable of planning 2 edges, then 3 and then the whole cross. Once you can do any cross blindfolded, you will be able to focus on the first pair while solving the cross. This will make you save huge amounts of time.

If you are interested in more information about solving the Rubik's cube blindfolded , have a look at our guide. I would also advice you to solve the cross on the bottom layer from the beginning. So flip the whole cube and start practicing with the cross on the bottom. It helps you to focus on unsolved faces, instead of focusing on the white face.

It also avoids to flip the cube when the cross is finished, which will save time too. The aim is to perform the moves continuously and to have a good transition between each step. Every second you do not rotate any face can be saved. It is possible that solving the cross on the bottom wastes time in the beginning but it will quickly make you improve. If it is too difficult for you, maybe you can try it later on But if you want to solve the cube under 20 seconds, that's a very important step.
