Fridrich (CFOP) – Stage 1. July 4th by Chris Durnford. If you have already read our beginner’s solution guide, you will already know how to do this step. 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 Rubik’s Cube. CFOP is the most frequently used speedsolving method for the 3x3x3 for the 3×3 Rubik’s Cube since have been set with CFOP, with the.

What’s even better is that these few algorithms are used in the full CFOP method anyway, so we’re not wasting any time! Now that you know the beginner method, you can begin to introduce the concepts in this guide into your tubik. So you’ve gone through the beginner’s method a few times, and maybe you can solve the cube unaided every time.
Rubil aren’t satisfied with people standing around for 2 minutes while you solve it because that guy at the office didn’t believe you. If they need to move clockwise, then use this algorithm:.
The cases for this step can all be solved intuitively if you have enough experience. Rather than relying on a big table of algorithms, F2L is best done intuitively. However, the second algorithm is much faster to perform, as it is essentially the same few moves performed three times. Czech speedcuber Jessica Fridrich is generally credited for popularizing it by publishing it online in Not until he first scrambled the pieces and attempt to put them back in order did he realize his cube made for a challenging puzzle.
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. Make a cross on one side by solving all edges of a given face. Included are all the algorithms and methods required to learn how to solve a Rubik’s cube. Rubik created the cube as a teaching tool so that his students could understand how to move parts of a 3D object independently without fundamentally altering or destroying it.
But the second algorithm is considerably quicker to perform, as you don’t have to adjust your hand position at all. However, there is such a list on the algorithms pagewhere you can see each F2L case and how to solve it.
PLL gets the same treatment, as we’ll be permuting the corners first and then the edges. However, it is NOT required. They don’t look scary at all, and there’s even some triggers in there that you’ve already seen! The next step is to solve the rest of the first two layers which is what F2L stands for at the same time, to get this:.
This works, and is an intuitive way to solve the problem, but the second solution is much simpler. 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.

Hopefully you find them useful: 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. Turning the whole cube in your hands is a slow waste of time.
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 ccfop looking at the rest of the cube to find the next F2L pair. This doesn’t disturb any of the other F2L spaces, ccop you rubi, see that the red-green pieces are looking rather unsolved and unhappy. I rubi, recommend that you keep using the 2-look algorithms until you feel confident with most of this speedcubing guide. The way it works is to split up the steps into two smaller steps each.

You can also order the table by trigger, which I think is much more conducive to eubik. Compare these two algorithms:. As you practise incorporating the techniques on this page into your solves, you will learn to ruvik the various other OLL and PLL situations, which will help immensely in their memorisation.
The last layer steps OLL and PLL involve first orienting the last layer pieces, then permuting them into their correct positions.

I’m not even kidding. You simply repeat these steps rubki each of the four corners, and solve each F2L pair in turn. David Singmaster published a layer-based solution in which proposed the use of a cross. 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.
This step aims to permute the edge pieces, which by now you have probably worked out is also called EPLL.
If you are thinking “how the dickens is anyone supposed to do this in 4. Don’t worry if you struggle!
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. It consists of four steps: It’s beautiful, and no horrid cube rotations. I have gone through each of these situations and chosen algorithms that I think are easy to both perform and learn, but you may feel differently.
Have a go on your cube, and see if you can work out how to solve any of the pairs. CFOP is the most frequently used speedsolving method for the 3x3x3 cube. The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers F2Lorienting the last layer OLLand finally permuting the last layer PLL.
If you do RU2R’, you can turn this into case 3. Orientation of the Last Layer. As mentioned above, the sections in this method don’t have to be learned sequentially. COLL and CLL both mean different things to other cubers, and sticking to convention makes things a lot easier for everyone involved.
