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.

There are, of course, many more cases than this, but most can be solved with the strategies above or can be reduced to one of the above cases. Fridrich first saw a Rubik’s Cube at the age of 16 in March It is up to you to find your own style and solution. The last layer is solved by first orienting and then permuting jeszica last layer of the cube using a few sets of algorithms.

But if you want to solve the cube under 20 seconds, that’s a very important step. This step 1 is the exact same of the step 1 of the beginners method.

The cases described below are designed to help you gain that intuition. But doing it with your left hand will be quicker! The OLL skip is the position where all the last layer is already oriented without performing any algorithm. Now insert the pair into its slot.

Don’t forget to align the centers pieces of the cube! Or do you feel like you need a better cube? She says she came with the idea of this method because it allows very fast inspection during the resolution. First, the”cross” is made on the first layer, consisting of the center piece and four edges.


It also avoids to flip the cube when the cross is finished, which will save time too. There are in total 21 PLLs which methof to the Fridrich method. Just put the solved face in front of you and you will need to permute the three remaining edges.

Simulating moves mentally will help you for the next solves and you will become more jezsica more familiar with efficient cross solving. You may be tempted to solve this case with your right hand.

Also remember that you have two hands and the left hand should not only be used to hold the cube. Having a PLL skip has a chance out of 72 to happen. It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method.

Here are the magic algorithms:.

The cross is done intuitively. Retrieved from ” https: Have a look at the Pochmann method.

The corner firsts methods that were the best at the time did not allow such a fast vision. Every algorithm will save you time.

Flipping the cube is the time when no move can be performed. If on one face the two corners have the same color, then they can be considered as solved and the other two will need to be permuted. If you are interested in mehtod information about solving the Rubik’s cube blindfoldedhave a look at our guide. Have a look at the following case:. It is of course quicker but also requires to learn a lot of formulas. Retrieved April 19, They are the only ones and the best way to solve them is metjod really instinctive.


Super-durable and solid stickers with vivid colors will not peel off or fade easily. Method inventors Speedcubers Cubers. Make sure that the colours of the other stickers on the edges are in this order: Vision and thinking should be much faster too.

A lot of algorithms to learn. Because if everything that is solved is in the back, then it is much easier to find what to solve next.

She invented it at the end of the s. If you have 0 corner to orient then you can directly move on to the next step. Methkd found all these cases intuitively, just with practice. Categories Cubers Method inventors Speedcubers.

Here is a photo of Jessica while practicing on the Rubik’s cube kethod. All the algorithms for this step are super easy and can be performed under a second. The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms.

Although the cases can be very different, some similar pattern often happen. It is recommended that you should start learning using the beginner method first, then use the Fridrich method fridriich you have become proficient at that.
