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.

You will need to perform the following algorithm: Retrieved from ” https: It is not complicated and you will remember them forever. Megaminx Pyraminx Crystal Skewb Ultimate. This is the fastest and the easiest Rubik’s cube solving method. You may be tempted to solve this case with your right hand. Sometimes, it is easier to first build the pair and then insert it. After you’re finished, just doing a D move or D’ will align the cross with the faces.

Every second metjod do not rotate any face can be saved.

Views Read Edit View history. This case will be solved in two steps. It doesn’t corner twist as often nor does it lock up. Most of the time, what slows you down is your inspection and your thinking.


They were used the jessifa after the other in the step 7 of the beginners method. It is usually done starting with the white colored squares. Here are the magic algorithms:.

It definitely friidrich much better than my other speed cubes. It is now time to start practicing! Here there are two different cases.

I will metnod you the orientation of the last layer in two steps. Menu 1 Fridrich method: The corner firsts methods that were the best at the time did not allow such a fast vision. Every time you solve a pair, you are actually using the empty slot of that same pair. In total, there are 57 OLLs. Every algorithm will save you time. Solving the corners first and then the edges. Fridrich method is also called CFOP. The last layer algorithm are quite difficult to find and identify by yourself.

It has to be maximum once per pair, ideally just once or twice during the whole solve of the F2L. Retrieved from ” https: It is possible that solving the cross on the bottom wastes time in the beginning but it will quickly make you improve.

Determining which case to use is very easy. This will make you save huge amounts of time. If you have 0 corner to orient then you can directly move on to the next step. At first you will only be capable of planning 2 edges, then 3 and then the whole cross. At first, we will do it in two steps: Super-durable and solid stickers with vivid colors will not peel off or fade easily.


How to Solve the Rubik’s Cube/CFOP

The national championship took place in May by which time Fridrich was averaging about 25 seconds. You should do it on the bottom because then it’s easier to locate the other pieces. Here is what it looks like with the animations:.

Metnod says she came with the idea of this method because it allows very fast inspection during the resolution. A lot of algorithms to learn. But if you want to solve the cube under 20 seconds, that’s a very important step. According to me, it is much more interesting to find all the cases by yourself.

For the edges orientation, you should already know all the cases. This differs from case 2 only by the orientation of the edge blue is up, not orange. Here is a photo of Jessica while practicing on the Rubik’s cube 3×3. As everything changes when rotating the cube, all your inspection will be hard to transpose.
