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.

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. Indeed, the whole cross is assembled on the bottom layer instead of the top. God’s algorithm Superflip Thistlethwaite’s algorithm Rubik’s Cube group.
How to Solve the Rubik’s Cube F2L, OLL and PLL « Puzzles :: WonderHowTo
It is usually done starting with the white colored squares. Views Read Edit View history. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time.
Instead, a simple U’ before the algorithm means that when you then pair the red-blue corner and edge piece, you avoid affecting the blue-orange pair.
Fortunately, there is a huge algorithm database for your perusal, where you can find the perfect algorithms for you. 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. For example, here are two ways of pairing the corner and edge pieces:. This leaves you with a very start-stop, stuttery solve as you rapidly perform an algorithm and then stop to find the next one.
Archived from the original on 26 September Remember when I said ‘wasting time is bad’? Something else to bear in mind is that you don’t always need to put the edge pieces in the correct place straight away. Views Read Edit View history. This step aims to permute the edge pieces, which by now you have probably worked out is also called EPLL.
CFOP Method – Wikipedia
I’m going to show you a slightly different way of approaching the last layer, so that you only need to know a few algorithms instead. You should do it on the bottom because then it’s easier to locate the other pieces. It simply solves each piece relative to each otherand then places them in one go.
You needn’t go through the steps in order – you can learn and practise each bit independently, falling back on the beginner method as and when you need it. If you are thinking “how the dickens is anyone supposed to do this in 4. The second option is this algorithm:.
From Wikipedia, the free encyclopedia. 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. Even though you can already solve this case using the beginner way, I would take the time to practise and learn this algorithm now.
As above, you might now need to turn the top layer to realign the corner pieces. Solve the classic wooden ball puzzle How To: These steps are solved using only one algorithm each.
Both have ff2l same effect, but a double layer turn is quicker. This step is called CPLLas it aims to permute the corners – that is, move them to their correct positions like this:.
How to Solve the Rubik’s Cube. This database is part of the speedsolving. David Singmaster published a layer-based solution in which proposed the use of a cross.
Then, once you know those few algorithms, you can begin to pll the rest of the last layer algorithms while always being able to fall back on the ones you know. To this end, the vast majority of the algorithms on this page are comprised of many Rs and Us, as they are easy to perform sorry lefties.
But you could also place the white-red piece by doing this:. Please help improve this section by adding citations to reliable sources. So the first algorithm orients all the last layer pieces makes them all face the right way, i. COLL and CLL both mean different things to other cubers, and sticking to convention makes things a lot easier for everyone involved.
In other languages Add links. I’m not even kidding. In this situation, the first algorithm uses the empty space between the red and blue faces to move the red-blue edge piece so it can be easily paired and inserted. Draw a circle outside a dot without lifting the pen How To: However, the second algorithm is much faster to perform, as it is essentially the same few moves performed three times.
You aren’t satisfied with people standing around for 2 minutes while you solve it because that guy g2l the office didn’t believe you. To do this, you need to look for ‘headlights’ – ol face where both top layer corners are the same colour presumably named due to their resemblance to the headlights of a car.
Retrieved 15 June Basic layer-by-layer methods were among the first to arise during the early s cube craze. I have found that the next step F2L is ff2l huge help for people to understand how to move cubies to where they want them, a skill that they can later use when returning to the cross.
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. Try practising going from a scrambled cube to completed F2L very slowly, and making sure you have a f2ll steady flow. You can also order the table by trigger, which I think is much more conducive to memorisation.
But now you’re hooked.
If you can intuitively solve every F2L situation you come across then jolly well done, but there are a few cases where there is just a better, faster, much less obvious algorithm to solve it. You might think that this sounds quite challenging, and you’d be right. Olk guide takes you through every step of the CFOP speedcubing method.
