You must solve the cross first. It can be done in 6 moves or less ~82% of the time and ≤7 moves % of the time. These are just optimal example solves; F2L. This method is called Fridrich Method, and also CFOP, because of the four To sum up, from four steps (C, F2L, OLL, PLL) we get seven parts the method is.

When talking about the advanced technique of solving the Rubik's Cube we have to mention the Petrus system and the Fridrich method (or full CFOP) which is used by the big majority of speedcubers these days. This advanced technique developed by Jessica Fridrich divides the puzzle. The most popular Speedsolving method is the CFOP (Cross, First 2 layers, Orientation of last layer, Permutation of last layer) a.k.a Fridrich Method. Unlike The beginner's method, the Speedsolving method focuses mainly about solving the Rubik's cube in the fastest and most. HOW TO SOLVE A RUBIK'S CUBE. Advanced Method. This is full CFOP (or Fridrich) method. 'CFOP' refers to the steps involved - Cross, F2L, OLL and PLL.

Please read this thread and do some forum searching prior to asking questions about becoming faster. First off, the most important factor is practice. No matter what method you use, or how many algorithms you know, you need to practice a lot to progress. With practice, you will be able to turn the cube faster, recognize cases ore quickly, and just in general gain a better understanding of the cube. You can even get sub 20 averages with a beginners method - but only if you practice a lot. No other factor is more important.

However, you only need to learn 7 algorithms to do this in 2 steps.

You permute move the pieces on the last layer to solve the entire cube. There are 21 algorithms. Cross This is completely intuitive, and is probably the hardest part in this method.

Having said that, you can still with a bit of practice, see the best cross solution in 15 seconds and execute it in well under 3 seconds. In fact, sub-2 cross is not even that hard. All cross can be solved in 7 moves, and a big majority of them only need 6 moves. However, you will need to spend a decent amount of time practising this step and the best way to do it is to solve it blindfolded.

## How to Speedsolve the Rubik's Cube

Take as long as you want to plan out your cross and solve it blindfolded. You should now decide whether you want to be colour neutral or, well, not colour neutral. This is explained further in the link below. If you're still confused, take the picture to my left.

This is fairly intuitive and easy so you should find all four pairs this way. For that, all we'll have to do is to "move" the edge piece one place left, to the L-U faces. Trigger the animation and see how it is done. The way to do it is by moving the corner to the right to the R-B-U faces by doing U', and then making an R turn, that way we will be able to make a U' turn and move the edge piece to the desired location, without moving the corner along with it, and without affecting any of the already solved cross pieces and other 3 slots.

Then we'll return the corner back to the Upper face by doing R'. The way to do it is by "moving" the edge piece one place right, to the R-U faces.

For that we'll use the exact same technique as the previous position: We'll move the corner to the R-B-U faces by doing U', and then make an R turn taking the corner piece down, so it won't be affected by the U turn of the next move , then we'll do the U turn to reposition the edge piece where we want it, and make an R' turn to get the corner back up.

Now the corner and edge pieces are completely paired and forms a block, all that left is to insert them into the slot by executing the first solving variation U2 R U' R'.

Note that also the following variations use the exact same technique: 4, 5, and 6. Case Example 3 This variation can be seen in first inspection a little bit harder for intuitive solution, however it is much easier than it looks!

Here is how it goes: We'll pair up the edge and corner piece to a block, and solve it by the first solving position. We'll have to flip the corner so the first-layer color white in our case will face to one of the sides, instead on facing top; then we'll pair up the corner with the edge piece to form a block.

Lucky us, it's done simultaneously: We'll turn the U face until the edge piece side color will fit the center piece below it In our case this is red, and requires a single U turn , then we'll make an R turn so the edge piece goes temporary to the middle layer. Now, we'll make a U2' turn to place the corner on top of the edge piece Pay attention: we have just paired them and created the block , and return the edge-corner block to the Upper face by doing R'.

Interesting thing is that while returning the edge piece to the top we used it to both pair the piece and flip the corner. Now the block is ready to be solved to the slot by executing the first solving variation U R U' R' Note that also the following variations use the exact same technique: 20, 21 and In variations where the corner or edge piece or both of them is inside the slot, usually the approach is to get the piece out of the slot back to the U face, adjust the corner-edge pieces to one of the solving positions, and insert them into the slot correctly.

## How to Get Faster Using the Fridrich/CFOP Method

F2L algorithms page Now, take your time and learn how all the different variations of the F2L are being solved. Focus on understanding how it is done rather than learning the "algorithms". In this step I focused on learning the basics of F2L, however the F2L is the step with the biggest potential for time reduce and improvement, with lots of advanced techniques which I show in the Advance F2L page: Minimizing cube rotations re-gripping Taking advantage of empty slots Multi-slotting After you feel comfortable intuitively solving the F2L, read my advance F2L techniques page.

There are 57 different possible variations or combinations of the last layer pieces orientations Not including the fully solved variation.

Therefore there are 57 different algorithms to learn to fully master the 1 look OLL. The 2 look OLL requires knowing only 10 algorithms, which some of them you should already know from the Rubik's cube beginner's method. All edges will become oriented. When 2 adjacent edges are oriented: Use the P orientation algorithm.

## CFOP Method

Orienting the LL corner pieces: There are only 7 possible variations of corner orientations when all the edges are already oriented. All 7 cases and their algorithms are in the first table of the OLL Algorithms page.

The OLL step is the "least rewarding" step in a matter of learning algorithms, meaning that the transition from 2 look OLL to 1 look OLL requires additional 47 algorithms- yet rewards in "only" around seconds. Full OLL becomes more relevant in sub 20 second solving and under.

Keep in mind that the PLL algorithms 4th step are more important and it is better to fully learn them 21 total before going for the full OLL. Fast OLL solving is a matter of knowing the algorithms, and fast fingertricks.

Though it is important to work on your fast execution of these algs, most of the progress and time-reducing will happen in the F2L Such practice will improve your turning speed which will make also your OLL faster. Recognition The algorithms are divided into sub-groups based on the shape they form on the U face e. P shapes, T shapes and lightning bolts shapes , which makes it much easier to quickly recognize the variation and execute the right algorithm.
