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. (what looks like a cross shape); F2L: Solving the first two layers completely (not hard as it sound:)); OLL (Orientation of Last Layer): Correctly orienting the last. This two-part video tutorial will teach you how to solve the Rubik’s Cube F2L, OLL and PLL. Make sure you have your Rubiks Cube notation.

Consider this situation, and the two approaches to solving it:. Why don’t you give it a try – go to the timer pageset inspection time to 15 seconds and see if you can produce a solution to the cross entirely in your head.
But now you’re hooked. Compare these two algorithms:. It’s ok, no one has to o,l.
But you could also place the white-red piece by doing this: Because it was taken already, that’s why. You can do this in whatever order you choose but I have arranged them in what I think is a sensible order to learn them – I have grouped similar algorithms, ooll put what I think are the olk ones first. You can also order the table by trigger, which I think is much more conducive to memorisation. It is difficult to teach intuition, but through practice it should eventually just ‘click’ in f2 head.
CFOP is heavily used and relied upon by many speedcubersincluding Rowe HesslerMats Valkand Feliks Zemdegs for its heavy reliance on algorithmspattern recognition and muscle memory ; as opposed to more intuitive methods such as the Roux or Petrus method.
But what is life without a bit of a challenge every now and then. This database is part of the speedsolving. Solve the olo wooden ball puzzle How To: Views Read Edit View history.
How to Speedsolve the Rubik’s Cube
However, knowing that you can solve this step using just one algorithm is useful during the learning process! Here’s a simple example:.
An intuitive way of thinking about this situation might produce something like the first algorithm, as it follows the usual principles of pairing the edge and corner piece and inserting them together. A trigger is simply a sequence of moves that is easy to perform very quickly, and the Sexy Move trigger comes up a lot. Both algorithms solve the F2L pair and use the same number of moves.
It’s quite an easy step, as kll is essentially the same as step 4 from the beginner guidewhich is to get a cross on the top face. I know, I fl2, I said that F2L should be solved intuitivelyand that you shouldn’t rely on a big ool of algorithms. This idea of finding an empty space on the cube and using it to build a corner-edge pair is crucial to F2L, as of course you want to be able to construct each of the four F2L pairs without disturbing any previously solved ones.
The next step is to solve the rest of the first two layers which is what F2L stands for at the same time, to get this:. Using this algorithm is much faster, as it makes a cross in one go. Ol completes the cube, which you ol know looks like this:.
If you only have one, then which algorithm you use depends on the direction that the other edges need to be cycled. You want a taste of the high-flying, rock and roll lifestyle of the speedcuber. It’s all very well and good being able to perform algorithms quickly, but perhaps the most important thing with F2L is to perform the algorithms continuously.
There are, however, some more optimal algorithms.

Megaminx Pyraminx Crystal Skewb Ultimate. Her main contribution to the ol, was developing the OLL and PLL algorithms, which together allowed any last layer position to be solved with two algorithms and was significantly faster than previous last layer systems.
What’s even better is that these few algorithms are used in the full CFOP method anyway, so we’re not wasting any time! Fortunately, there is a huge algorithm database for your perusal, where you can find the perfect algorithms for you.
It can be quite difficult certainly so if you’ve o,l just started doing it upside down but with practice it will become very easy to isolate only the four edge pieces you need and formulate a basic plan to get them into a cross.
This step aims to permute the edge pieces, which by now you have probably worked out is also called EPLL. Algorithm helper Toggle algorithm helper. While this is also an excellent life tip, some situations are just better handled on a specific side of the cube. As mentioned above, the sections in this method don’t have to be learned sequentially.
It consists of four steps: You will have to rely on them in practically every solve d2l you learn every other OLL and PLL algorithm, which will take you some time and effort.
