The name CFOP comes from the steps involved (Cross, F2L, OLL, PLL), and you may also see it referred to as the Fridrich method (after Jessica Fridrich, who. CFOP (Cross, F2L, OLL, PLL, pronounced C-F-O-P or C-fop) is a It is also known as the Fridrich Method after its popularizer, Jessica Fridrich. 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 greatly reduces the number of cases; 2-look PLL has 6 cases. However, there is such a list on the algorithms pagewhere you can see each F2L case and how to solve it. Go on, I’ll wait right here. I actually use [r’ R] okl of M. Views Read Edit View history. However, the kll algorithm is much faster to perform, as it is essentially the same few moves performed three times.
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 olo previously solved ones.
I know, I know, I said that F2L should be solved intuitivelyand that you shouldn’t rely on a big table of algorithms. Why don’t you give it a try – go to the timer pageset inspection time to 15 seconds and see frivrich you can produce a solution to the cross entirely in your head. For example, here are two ways of pairing the corner and edge pieces:. World Cube Association Regulation A3a1 states that a competitor has up to 15 seconds of inspection time before attempting a solve, and you would want to be spending this time mentally formulating a complete solution to the cross which you could then execute very quickly at the start of your solve.

The way it works is to split up the steps into two smaller steps each. They also tend to use more double layer turns like d as opposed U y’. Learn 5 Tips to solve a Rubik’s Cube much faster! It’s ok, no one has to know. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time.
The most recognized OLL algorithm. 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.
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. The completion of this step leaves one with just the last layer, typically placed on top. Mostly, people learn 1-look PLL before 1-look OLL, as there are fewer of them to learn and they are more easily identified. Retrieved from ” https: 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.
Consider this situation, and the two approaches to solving it:. Here’s a similar example:. First, you can just use the above algorithm anyway, which will make some headlights for you to solve as above.
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. After getting the top cross, there are seven unique cases to complete the OLL. A Make sure to align the edges with the second-layer centers. I would recommend that you keep using the 2-look algorithms until you feel confident with most of this speedcubing guide.

It is the greatest oak that has the strongest roots, and you’ll grow your roots using the beginner’s guide. 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.
By using this site, you agree to the Terms of Use and Privacy Policy. Fridrich switched to F2L later in F2L can be a little difficult to get your head around. There are, however, a few situations you might find yourself in where this procedure is not quite so obvious.
The first algorithm either requires you to shift your hand position to twist the F face or start using some peculiar thumb movements.
In rfidrich following example, you can see that the ‘headlights’ are on the Front face, as the top layer corners are both blue. I assure you that the rabbit hole goes even deeper than that, and every situation actually has multiple algorithms for your learning pleasure.
CFOP method
Watch my super fast 7. Try to also remember that you probably have two hands. Headlights to be faced to the left. If you need to swap opposite edges, you can use this algorithm:. Wasting time is bad. The last B turn is done by the right hand index finger. As mentioned above, the sections in this method don’t have to be learned sequentially. 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.
There are five such cases that you should learn the algorithmic solution for, and they’re all in this nice little table:. At this stage, a lot of people still find it quite difficult to intuitively manipulate the cube.
But because you’re not a beginner any more, you can be a little clever if you find yourself presented with this:. Instead, really try and solve each case intuitively. It is recommended that you solve the cross on the bottom, left, right or back face and that you become familiar doing the cross with all colors; not just one. But not exactly the same, as you’ll have noticed – the cube is upside down.
Now that your top layer has been oriented, it’s time to permute it. However, note that this is a few seconds slower. God’s algorithm Superflip Thistlethwaite’s algorithm Rubik’s Cube group.
