There are 41 different variations for solving the corner-edge pieces in the F2L step. Many of these cases are very similar to each other (mirrors) and therefore. F2L Algorithms (First 2 Layers). Developed by Feliks Zemdegs and Andy Klise. Images sourced from Conrad Rider’s VisualCube. 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.

First Two Layers (F2L) of Fridrich Speedcubing Method – Wiki
But just look at it. Top of the page. Instead, the pieces that do get affected are ones you don’t care about, as they were occupying the space that you want to put the red-blue pair into. Indeed, the whole cross is assembled on the bottom layer instead of the top. They don’t look scary at all, and there’s even some triggers in there that you’ve already seen! You now know the basic ideas of F2L.
You will also have noticed that the first two brackets are written in red. As mentioned above, the sections in this method don’t have to be learned sequentially.
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. F2L First 2 Layers is a way of continuing after solving the cross. The red-blue F2L ff2l is used in all of these diagrams so the sticker that is hidden would be either red or blue, depending on which sticker is shown. About Me My Records. Very slow indeed, about seconds per quarter turn of a face.
But you could also place the white-red piece by doing this: F2L combines steps 2 and 3 of my beginner solution, but it requires approximately the same number of moves as step 3 alone. Just like the beginner guide, the rest of the last layer isn’t an intuitive thing you can just work out if you can, you and your mega-brain should probably be working for NASA or something.
Just like with the happy red-green pieces before, sometimes you will come to an F2L situation that you’ve solved many times, but solve it in a different way because you want to set up the next F2L pair for easy solving. This section does not cite any sources. Here’s a simple example:. In these cases, it is assumed that the corner and edge are either in their respective locations or in the top layer. Floppy Cube 1x3x3 Rubik’s Domino 2x3x3. Well here is where your journey begins.

That’s called 2-look PLL. In this step, a first-layer corner henceforth referred to as fricrich corner” and the middle-layer edge above it “the edge” are inserted at the same time into their designated locations “the slot”. This might seem like a trivial difference to you, but each little pause adds up, fridruch when you’re trying to really push down your solve time every second counts.
Or you can check the advanced F2L section. If one or both pieces are stuck in another slot, you can simply move them out by inserting random pieces from the top layer into that slot. However, the second algorithm is much faster to perform, as it is essentially the same few moves performed three times.
To do this, you need to look for ‘headlights’ – a face where both top layer corners are the same colour presumably named due to their resemblance to the headlights of a car. From Wikibooks, open books for an open world.

David Singmaster published a layer-based solution in which proposed the use of a cross. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time. This practise is called lookaheadand is vital if you want to achieve solve times under 20 seconds. Well go ahead, but don’t blame me when you’re trying to make friends with other speedcubers and you have to listen to “Wait, do you mean COLL as in orienting and permuting last layer corners while preserving edge orientation, or just orienting the corners and preserving edge orientation but ignoring all last layer permutation?
It’s quite an easy step, as it is essentially the same as step 4 from the beginner guidewhich is to get a cross on the top face. U2 R U2 R’. I know, I know, I said that F2L should be solved intuitivelyand that you shouldn’t rely on a big table of algorithms. At this stage, a lot of people still find it quite difficult to intuitively manipulate the cube. 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.
This means that doing the cross on the bottom is difficult, as they have come to rely on algorithms for situations that are suddenly upside-down.
F2L Algorithms Page
But you could also place the white-red piece by doing frisrich. In most cases those algorithms are simply the intuitive pair-and-insert procedure optimized with moves such as x, y, d, etc.
I would recommend that you keep using the 2-look algorithms until you feel confident with most of this speedcubing guide. This method was first developed in the early s combining innovations by a number of speed cubers. This doesn’t disturb any of the other F2L spaces, but you can see that the red-green pieces are looking rather unsolved and unhappy.
Make sure that the colours of the other stickers on the edges are in this order: As you practise incorporating the techniques on this page into your solves, you will learn to recognise the various other OLL and PLL situations, which will help immensely in their memorisation. Case 5 Corner on Top, Edge in Middle.
