It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method. This method is named after its creator, Jessica Fridrich. He said: “I am using the Fridrich method.” I asked with a surprise in my voice: ” You actually memorized ALL algorithms?” His answer was: “No. 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.

Solving the corners first and then the edges. Lightweight and comfortable in the hand. There is a third tricky case. For example, here are two ways of pairing the corner and edge pieces:. Then then ones with two corners to orient and finished with the last two.
It is of course quicker but also requires to learn a lot of formulas. Once you have located the two corners that are of the same color, the other two need to be permuted. 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.
This is a lot less algorithms than the OLLs. 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.
At this stage, a lot of people still find it quite difficult to intuitively manipulate the cube. Therefore, rotate the cube as little as possible.
The cases described below are designed to help you gain that intuition. Try practising going from a scrambled cube to completed F2L very slowly, and making sure you have a continuous steady flow.

The national championship took place in May by which time Fridrich was averaging about 25 seconds. To find the pattern on the corners, just focus on the side colors of the corners. You might think that this sounds quite challenging, and you’d be right.
This page was last edited on 17 Decemberat 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. Turning the whole cube in your hands is a slow waste of time. By using this site, you agree to the Terms of Algirithms and Privacy Policy.
How to Solve the Rubik’s Cube/CFOP
Ffidrich the cross 3 Step 2: 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. In total, there are 57 OLLs. Even if you understand the basic ideas above, it isn’t always obvious how best to proceed.
If you clicked the link to the algorithm page before, you’ll have seen that the list is indeed quite long. Or they are not symmetric: Aogorithms is now time to start practicing! Why not see how well you can do with the timerand please do get in touch if you have anything you’d like to say, or leave a comment below!
Full CFOP takes some dedication. The cross is done intuitively. Both have the same effect, but a double layer turn is quicker. The algorithms you will find will make sense and therefore will be easy to learn and to perform fast.
Consider this situation, and the two approaches to solving it:. It does take time to get used to, and it doesn’t really matter how long you take when you’re practising.
Why don’t you give it a try – go to the timer pageset inspection time to 15 seconds and see if you can produce a solution to the cross entirely in your head. Categories Cubers Method inventors Speedcubers.
