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.

There are lots of algorithms for doing this, but I like this one the best.
CFOP Method – Wikipedia
This step is called CPLLas it aims to permute the corners – that is, move them to their correct positions like this:. Lol first approach involves taking each edge piece, putting it above where it needs to go, and turning the appropriate face twice to place the piece on the bottom layer.
You should do it on the bottom o,l then it’s easier to locate the other pieces. Solve the classic wooden ball puzzle How To: There are, however, a few situations you might find yourself in where this procedure is not quite so obvious. But sometimes it can be advantageous to disturb unsolved spaces by choosing a space to build your corner-edge pair that also assists the creation of the next pair. Using this algorithm is preferable than using the first algorithm twice, as it will be much faster to perform.
The major innovation of CFOP over beginner methods is its use of F2L, which solves the first two layers simultaneously. 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.
Indeed, the whole cross is assembled on the bottom layer instead of the top.
Of course, when you’re just sat at home on a lazy Sunday idling the afternoon away with a Rubik’s Cube you likely won’t be paying much attention to official WCA competition rules, but it does give you something to aim for.
Even though you can already solve this case using the beginner way, I would take the time to practise and learn this algorithm now. This advice applies to all of steps in this guide, but it is most important during F2L and step 1, the cross. But now you’re v2l. All of that being said, I can oll you some situations to hopefully make the process easier. The second option is this algorithm:.
Fortunately, there is a huge algorithm database for your perusal, where you can find the perfect algorithms for you. Czech speedcuber Jessica Fridrich is generally credited for popularizing it by publishing it online in 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.
So instead, what we’re going to do, you and I, is cheat a little. If you perform each algorithm as quickly as humanly possible, you don’t leave yourself much time to analyse the cube and isolate the next corner-edge pair you want to solve.
You aren’t satisfied with people standing around for 2 minutes while you solve it because that guy at the office didn’t believe you. However, knowing that you can solve this step using just one algorithm is useful during the learning process!
So the first algorithm orients okl the last layer pieces makes them kll face the right way, i.
But the second algorithm is considerably quicker fl2 perform, as you don’t have to adjust your hand position at all. It does take time to get used to, and it doesn’t really matter how long you take when you’re practising.
Archived from the original on The algorithm page has each OLL algorithm ordered by the shape they resemble, so you can find which situation you need easily. This can’t be solved as simply, but the idea is exactly the same. Because it was taken already, that’s fl2.
Disassemble and reassemble olk 4×4 Rubik’s Cube puzzle How To: This differs from case 2 only by the orientation of the edge blue is up, not orange. OLL consists of 57 different algorithms. Have a go on your cube, and see if you can work out how to solve any of the pairs.

Views Read Edit View history. The important part of F2L is being able to solve each of the pairs without affecting any of the other previously solved pairs. If you need to swap opposite edges, you can use this algorithm:. Maintain your Rubik’s Cube in six easy steps How To: Don’t forget to align the centers pieces of the cube! Now insert the pair into its slot. If you do UF’U2, you can turn this case into case 2 above. I know, I know, I said that F2L should be solved intuitivelyand that you shouldn’t rely on a big table of algorithms.
I would recommend that you keep using the 2-look algorithms until you feel confident with most of this speedcubing guide. Retrieved from ” https: Compare these two algorithms:.
The strategy here is to join a corner of the first layer with the edge that goes above it, then insert that pair. Solve the Cast Heart metal puzzle from Kll News: Not having to turn the cube over after completing the cross on the top layer saves a lot of time, and it also means that you can be looking for the pieces for the next fl whilst completing the cross on the bottom.
First, you can just use the above algorithm anyway, which will make some headlights for you to solve as above.
But you could also place the white-red piece by doing this: This page was last edited on 17 Decemberat The next step is to solve the rest of the first two layers which is what F2L olp for at the same time, to get this:. If they need to move clockwise, then use this algorithm:.
