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.

This will allow you to focus on the next step, F2L while doing the cross.

Categories 3x3x3 other substeps. This works, and is an intuitive way to solve the problem, but the second solution is much simpler. Don’t forget to align the centers pieces of the cube! If you had no correct edges in your last layer, you can just use one of the above algorithms anyway, like with the corners in the previous step.
Fridrich (CFOP) Method
The definition is a little different depending on the subject or who you are talking to. These miscellaneous techniques can help you improve your speed in the step.
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 frirdich head. As you might well imagine, this means that full CFOP has a lot of algorithms in it – one for every situation you might encounter.
But not exactly the same, as you’ll have noticed – the cube is upside down. Unsourced material may be challenged and removed. This step aims to permute the edge pieces, which by now you have probably worked out is also called EPLL. You should do it on the bottom because then it’s easier to locate the frirdich pieces.
Here’s a simple example:. CFOP is heavily used and frkdrich 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.
I shall now try to explain some further concepts that you can use to improve your F2L. This step is called CPLLas it aims to permute the corners – that is, move them to their correct positions like this:. That’s why there’s a big scary table of algorithms lurking on the algorithms pagebut because we’re using our clever 2-look shortcut, you only need to know the following seven.
Czech speedcuber Jessica Fridrich is generally credited for popularizing it by publishing it online in Maybe you’re even getting pretty good, and can consistently do it in under 2 minutes. I have not had time to make sure all these moves are correct. I assure you that the rabbit hole goes even deeper than that, and every situation actually has multiple algorithms for your learning pleasure.
Both algorithms solve the F2L pair and use the same number of moves. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time. Step 1 – The Cross This step is the same as the beginner method – forming a cross on the first layer to get this: Most F2L cases consist of two parts.
First Two Layers
The major innovation of CFOP over beginner methods is its use of F2L, which solves the first two layers simultaneously. Learn the intuitive steps first and fully understand how the moves work.
Twisty Puzzles Online Stores International. This step was proposed by Hans Dockhorn and Anneke Treep. Go on, I’ll wait right here.
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. So for OLL, instead of orienting every piece in the last layer at once, we’ll do the edges first and then the corners.
In these cases, it is assumed that the corner and edge are either in their respective locations or in the top layer.
It is usually done starting with the white colored squares.
