How to Solve a 3 by 3 by 3 Rubik's Cube: This is a Instructable how to solve a 3 by 3 by 3 rubik's cube. All movments are self invented. And I wanted to say, that I'm german, so if you find any spellingmistakes please tell me. Step 3 is this fix. Step 3 can seem incomprehensible before you 'get' it, but it is really the simplest step in the method. Beginner If you don't like the beginner instructions, take a look at the intermediate ones. You may like that approach more. Basically, we need to do 2 things in step 3. Edges to their layers. Every yellow piece needs to be grouped on one layer and the white pieces to the other according to the color of the center pieces. Swap the left-bottom and the top-right edges using this algorithm: (R D2 F) D2 (F D2 F R) 4. In the last step we have to put all edges to their final position.

Dan di dalam rumus rubik 3×3 ini kita akan membahas secara lengkap dengan mudah, cepat, dan bergambar agar lebih mudah dipahami.
(Redirected from Fridrich Method)
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. This method was first developed in the early 1980s combining innovations by a number of speed cubers. Czech speedcuber and the namesake of the method Jessica Fridrich is generally credited for popularizing it by publishing it online in 1997.[1]
The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers (F2L), orienting the last layer (OLL), and finally permuting the last layer (PLL).
History[edit]
Basic layer-by-layer methods were among the first to arise during the early 1980s cube craze. David Singmaster published a layer-based solution in 1980 which proposed the use of a cross.[2]
The major innovation of CFOP over beginner methods is its use of F2L, which solves the first two layers simultaneously. This step was not invented by Jessica Fridrich. According to Singmaster's report on the 1982 World Rubik's Cube Championship, Fridrich was then using a basic layer method, while Dutch competitor Guus Razoux Schultz had a primitive F2L system.[3]
The last layer steps OLL and PLL involve first orienting the last layer pieces, then permuting them into their correct positions. This step was proposed by Hans Dockhorn and Anneke Treep.
Fridrich switched to F2L later in 1982. Her main contribution to the method was developing the OLL and PLL algorithms, which together allowed any last layer position to be solved with two algorithms and was significantly faster than previous last layer systems.[4]
CFOP, with small tweaks, is by far the most popular method that top cubers use. Users include Mats Valk, Feliks Zemdegs, and Max Park.

There also exist many advanced extension algsets to be used in companion to CFOP, such as COLL,[6] Winter Variation,[7] VLS, ZBLL, and more. However, it is not necessary to learn them in order to solve the cube.

CFOP is heavily used and relied upon by many speedcubers, including Rowe Hessler, Mats Valk, and Feliks Zemdegs, for its heavy reliance on algorithms, pattern recognition, and muscle memory, as opposed to more intuitive methods such as the Roux or Petrus methods. The majority of top speed cubers on the WCA ranking list are CFOP solvers, including the current 3x3x3 single world record holder (Yusheng Du (杜宇生)), with a time of 3.47 seconds.[8][9]
