The name CFOP comes from the steps involved (Cross, F2L, OLL, PLL), and you may also see it referred to as the Fridrich method (after Jessica Fridrich, who. CFOP (Cross, F2L, OLL, PLL, pronounced C-F-O-P or C-fop) is a It is also known as the Fridrich Method after its popularizer, Jessica Fridrich. The CFOP Method (Cross – F2L – OLL – PLL), sometimes known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3.

Bar is facing to the left. This is for the same reason as the cross in step 1 – you need to be able to look at the cube and produce an efficient way of solving each F2L pair. The idea of F2L is to pair each of the four bottom layer corners with the corresponding edge piece and then insert them into the correct place. Here’s a simple example:. If doing the cross on the bottom takes much longer than when doing it on the top, don’t be disheartened!
Instead, it is much better to perform the algorithms slightly more slowly in one continuous stream. This step is called CPLLas it aims to permute the corners – that is, move them to their correct positions like this:.
David Singmaster published a layer-based solution in which proposed the use of a cross. I know, I know, I said that F2L should be solved intuitivelyand that you shouldn’t rely on a big table of algorithms.
As a result, many who learned from her website began to call this method the “Fridrich Method,” which explains the common use of the term today. Compare these two algorithms:. Wasting time is bad.
You can also order the table by trigger, which I think is much more conducive to memorisation. If you’ve just arrived at this website looking to learn how to solve a Rubik’s Cube and thought to yourself “Beginner my left foot, I’m starting with the speed cubing guide, that sounds fast”, then I warn you now: The first algorithm does successfully pair the red-blue corner and edge pieces, but it also lifts out the blue-orange pair from its proper place, thereby undoing any hard work it took to put it there.
At this pace, you remove the temptation to focus only on the pieces that you are currently applying an algorithm to, and you can easily be looking at the rest of the cube to find the next F2L pair.
Maybe you’re even getting pretty good, and can consistently do it in under 2 fridricg. Therefore, rotate the cube as little as possible. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time. The corner pieces should then be permuted correctly in relation to each other – but you might need to turn the top layer so that they are back in the right places.
CFOP Method – Wikipedia
The last layer steps OLL and PLL involve first orienting the last layer pieces, then permuting them into their correct positions. There are, however, a few situations you might find yourself in where this procedure is not quite so obvious. In reality, many developments were made in the early ’80s by other cubers who have contributed to the method in its current form.
Czech speedcuber Jessica Fridrich is generally credited for popularizing it by publishing it online in You’re ready to take your first look. Fill in the four slots between the cross pieces, one slot at a time.

They are there so you can see an optimal way to solve each case, but try to not rely on them for every single F2L case you encounter. Because it was taken already, that’s why. Consider this situation, and the two approaches to solving it:. 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.
Both have the same effect, but a double layer turn is quicker. Then, once you know those few algorithms, you can begin to learn the rest of the last layer algorithms while always being able to fall back on the ones you know.
But the second algorithm is considerably quicker to perform, as you don’t have to adjust fridricj hand position at all.
Headlights facing to the right when L shape is correctly positioned. Fridrich switched to F2L later in Her main contribution to the method 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 fridridh systems. Distinguished from the Sune by the side the non-oriented corners are facing.
You want to eliminate wasted time searching okl pieces. It’s easier to perform the quick trigger first and then add on the U’, as opposed to modifying a well-practised sequence.
