You want to learn the Fridrich but do you own a decent cube? I would advice you to ckbe the MoYu Aolong v2, best speed cube fridroch Speedup your solving time without any effort. It doesn’t corner twist as often nor does it lock up. Good control of the cube. It definitely turns much better than my other speed cubes. Super-durable and solid stickers fdidrich vivid colors will not peel off or fade easily. This moyu speed cube 3×3 comes pre-lubricated and tensioned. Advanced solution for Rubik’s cube 3×3.

We are now going to have a look at the Fridrich method. This is the fastest and the easiest Rubik’s cube solving method. Most of the world fastest speedcubing athletes use the Fridrich method to solve the Rubik’s cube.

CFOP Method

It is the key to solve the cube under 20 seconds or even 10 seconds if you firdrich master the method. This method frivrich named after its creator, Jessica Fridrich. She invented it at the end of the s.

She says she came with the idea of this method because it allows very fast inspection during the resolution. The corner firsts methods that were the best at the time did not allow such a fast vision.

Here is a photo of Jessica while practicing on the Rubik’s cube 3×3. The Fridrich method is only made up of 4 steps but also full of algorithm to learn.

If we consider the first two layers as solved intuitively, there is in total 78 algorithms to learn to solve the last layer: Thankfully, you do not need to learn everything at once and each of these two steps can be separated in two sub-steps.

The sub-steps are solving the edges and then the corners. This step 1 is the exact same of the step 1 of the beginners method. The basics are described in detail on our page which presents how to solve a Rubik’s cube. But now, the cross needs to be solved fast.

Every cross can be solved in under 10 moves. 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 blindfoldedhave 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. Although the cases can be very different, some similar pattern often happen. I am going to give you a few techniques to solve these cases. I found all these cases intuitively, just with practice. Memorizing them will save you time.

After you’re finished, just doing a D move or D’ will align the cross with the faces. When the cross is prepared a half turn to the solved position, it is particularly easy because all you need is to focus on opposite colors.

Once finished, a D2 move aligns the cross. While doing the last D move, you can start inspecting for the next step of the resolution. These techniques are very helpful.

It is now time to start practicing! Do not under-estimate the progress you can make by just looking at the cube and trying to figure out the cross. Sometimes you can even take a minute to think on how to solve the cross. Simulating moves mentally will help you for the next solves and you will become more and more familiar with efficient cross solving. There is no general rule on the best way to solve the cross though.

Everyone has his own technique and his way of solving the cross. It is up to you to find your own style and solution. A new speedcuber just appears! The idea is very easy: Solve the first two layers at once.

More precisely, every time you solve a corner, just associate the corresponding edge and solve both at the same time. This corner and edge are called a pair.

Sometimes, it is easier to first build the pair and then insert it. Some other times, we build the pair and insert it at the same time. There are many websites presenting solving formulas for the first two layers. According to me, it is much more interesting to find all the cases by yourself. It is not complicated and you will remember them forever. To do this, I will still help you by showing you a few basic cases. From these 3 cases, you should be able to deduce the entire solve.

They will be presented with an example. The basic idea of the first 2 layers is to pair the edge and the corner. And this needs to be done while inserting them at the correct place.

On the following example, we can see that a simple rotation of the right face will pair the red white bleu corner and the red blue edge.

The rotation of the upper layer will then bring cjbe pair to where it needs to be once solved. Finally the R’ move will complete the solve of the pair. Here fridfich the two main ways for inserting a pair, when the white of the corner is not located on top. Length moves will appear here Algorithm.

There is a third tricky case. This case occurs when the white corner has the white on top. This case will be solved in two steps. 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. Frifrich 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.
