Jessica Fridrich Distinguished Professor , Fax: () URL: E-MAIL: fridrich (AT) binghamton. edu. Richard can solve the cube blindfolded and willingly shares with us his method. I met Richard in April and he showed me his incredible skills in person. The Fridrich method or the CFOP method (cross, F2L, OLL, PLL) is a fast method for solving the Rubik’s Cube created by Jessica Fridrich. It consists of four.

From these 3 cases, you should be able to deduce the entire solve. When the metgod is prepared a half turn to the solved position, it is particularly easy because all you need is to focus on opposite colors.

How to Solve the Rubik’s Cube/CFOP

Here are the magic algorithms:. If you are about to turn the cube, always make sure that you put the pair you are solving in the back. But now, the cross needs to be solved fast. Don’t forget to align the centers pieces of the cube! Jessicaa was one of five cubers who advanced into the finals, among them, Mirek Goljan. Jessica Fridrich works as a professor at the Department of Electrical and Computer Engineering at Binghamton University and specializes in digital watermarking and forensics.

Once finished, a D2 move aligns the cross. To do this, I will still help you by showing you a few basic cases. Everyone has his own technique and his way of solving the cross. Take your time and try to anticipate. The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms.


That is a great first goal and will help you to solve the Rubik’s cube under 20 seconds. The first layer corners and edges of the second layer are put into their mwthod positions simultaneously four pairs.

Lightweight and comfortable in the hand. Nothing new on this step. Memorizing them will save you time. Vision and thinking should be much faster too. This case occurs when the white corner has the white on top.

This is probably the hardest part of the Fridrich method. Either 2, 3 or 4 corners are incorrectly oriented.

The strategy here is to join a corner of the first layer with the edge that goes above it, then insert that pair. It is the first step to the full Fridrich method, used by frivrich. The OLL skip is the position where all the last layer is already oriented without performing any algorithm.

There are, of course, many more cases than this, but most can be solved with the strategies above or can be dridrich to one of the above cases. This is the fastest and the easiest Rubik’s cube solving method. I would advice you to get the MoYu Aolong v2, best speed cube ever! She invented it at the end of the s.

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. I found all these cases intuitively, just with practice. If you mehhod RU2R’, you can turn this into case 3. Retrieved April 19, It is of course quicker but also requires to learn a lot of formulas. To know it fully there are about 80 algorithms to learn and that is why I am going to first introduce an intermediary method.


Or do you feel like you need a better cube? Megaminx Pyraminx Crystal Skewb Ultimate. You should do it on the bottom because then frierich easier to locate the other pieces.

Not turning the cube on this special case saves you about seconds. It is not complicated and you will remember them forever. Now you have everything to find the best F2L algorithms using Fridrich method. Categories Cubers Method inventors Speedcubers. This will be very useful if you want to communicate with other speedcubers about a specific algorithm. It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method.

The basics are described in detail on our page which presents how to solve a Rubik’s cube.
