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.

Not only will it help you speed up whenever you find yourself with a dot on the last layer, but when you see this algorithm again during proper 1-look OLL, you’ll feel all smug because you already know it.
This will be awkward the first few times you attempt it, but it is certainly worth practising. It can be quite difficult certainly so if you’ve only just started doing it upside down but with practice it will become very easy to isolate only the four edge pieces you need and formulate a basic plan to get them into a cross.
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. Solve the wooden ball puzzle How To: Using this algorithm is much faster, as it makes a cross in one go. But not exactly the same, as you’ll have noticed – the cube is upside down.
How to Solve the Rubik’s Cube.
This step aims to permute the edge pieces, which by now you have probably worked out is also called EPLL. They don’t look scary at all, and there’s even some triggers in there that you’ve already seen! Speedcubing Guide So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time. But the second algorithm is considerably quicker to perform, as you don’t have to adjust your hand position at all.
The second option is this algorithm:. The cases described below are designed to help you gain that intuition. A trigger is simply a sequence of moves that is easy to perform very quickly, and the Sexy Move trigger comes up a lot.
Move on to the next sections, but keep starting with the cross on the bottom.
Learning and practising this method can take you all the way to the top of the game – it is used by a lot of the top speedcubers to set world records, including the current staggeringly low time of 4. Going slowly isn’t better – going faster is better, but you’ll get faster by going slower.
Through practice, your lookahead will improve to a point where you can perform every algorithm very quickly, but without losing the ability to know what you’re doing next.
Solve a Rubik’s Cube in 5 minutes How To: 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. Have a go on your cube, and see if you can work out how to solve any of the pairs.
David Singmaster published a layer-based solution in which proposed the use of a cross. It does take time to get used to, and it doesn’t really matter how long fl2 take lll you’re practising. Views Read Edit View history. Wasting time is bad. 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.

CFOP Method – Wikipedia
If you do RU2R’, you can turn this into case 3. You simply repeat these steps for each of the four corners, and solve each F2L pair in turn. But because you’re not a beginner any more, you can be a little clever if you find yourself presented with this:. The important part of F2L is being able to solve each of the pairs without affecting any of the other previously solved pairs. 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.
Share Your Thoughts Click to share your thoughts. 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.
You now know the basic ideas of F2L.
So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time. You have two options here. This leaves you with a very start-stop, stuttery solve as you rapidly perform an algorithm and then stop to find the next one. 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. Full CFOP takes some dedication. Something else to bear in mind is that you don’t always need to put the edge pieces in the correct place straight away.
This lll was last edited on 17 Decemberat This step is called CPLLas g2l aims to permute oll corners – that is, move them to their correct positions like this:. Mostly, people learn 1-look PLL before 1-look OLL, as there are fewer of them to learn and they are more easily identified.
This step was proposed by Hans Dockhorn and Anneke Treep. Step 1 – Ol Cross This step is the same as fl beginner method – forming a cross on the first layer to get this: As you might well imagine, this means that full CFOP has a lot of algorithms in it – one for every situation you might encounter. I shall now try to explain some further concepts that you can use to improve your F2L.
Now insert the pair into its slot.
