Rubik’s cube may be perceived as part of a kid’s play or toy. At first glance, it may seem to be a simple cube with different color patterns but solving it is not simple. It requires persistence. Studying the different methods and mastering them is the key to solving Rubik’s cube.
A Deeper Insight
Jessica Fridrich had developed one of the methods in Rubik’s, which was known as the Fridrich Method. Unlike the beginner’s method, the Fridrich Method or popularly known as CFOP, is a speedcubing method for it can solve the Rubik in fewer moves. Using the Cross, first two layers, The Orientation of the last layer, Permutation of the last layer or CFOP for brevity can drastically solve the Rubik in just more or less 56 moves which usually takes around more or less 110 moves using the beginner’s method.
It is advisable, however, that one must first obtain a mastery of the beginner’s method before leveling up to the CFOP. The gauge if an individual obtained a level of mastery in the beginner’s method once he or she was able to solve the Rubik’s Cube at a speed of around 1and a half minutes to around two minutes.
Four Necessary Steps of Solving Rubik’s Cube in the Fridrich Method
- Cross: The first step is for you to solve the first layer by having the four edges formed in the shape of a cross.
- F2L (First Two Layers): Proceed to a analyze and solve the first two layers
- Orientation of the Last Layer (OLL): The last layer corners and edge pieces must be correctly placed.
- Permutation of the Last Layer (PLL): This is the last phase wherein you can successfully solve the Rubik’s cube by setting the edge pieces and the last layers in their proper place.
A Microscopic Analysis of the CFOP Method Step-wise
The initial step in solving the Rubik’s Cube is to solve the first layer and shape it into a cross. Basically, the initial step of solving it and having it in the shape of a cross is similar to the beginner’s method, with a slight difference in how it is being solved. Usually, in the beginner’s method, the first layer is being solved on the top, thus making the player have the cube flip upside down, thus incurring more time in solving the first layer. The CFOP solves the first layer not from the top but from the bottom, giving a quicker phase transition to the next level. This method will drastically reduce the time in solving the first layer.
Solving it from the bottom instead of from the top was seen as a key principle in attaining speed in solving the Rubik’s cube. At first, this process of solving it from the bottom may seem to be complicated and difficult. However, it gets easier once you get acquainted and are constantly being put into practice. One key factor that must be considered is focusing on one color to solve. In this way, you will gain familiarity with the color scheme and eventually memorize it. Familiarity and memorizing the color scheme will make it easier to move forward to the second step, which is the F2L step.
First Two Layers (F2L)
Comparably the F2L step is similar to the Beginner’s Method, specifically on the second and third steps. In the second layer, there is a need to solve the eight pieces by placing the four corner pieces and four middle layer edge pieces. It can be done by placing and pairing the corner pieces and the edge pieces by having them properly placed on their slots.
The second step will spell the difference as to the time gain in solving the Rubik’s cube. To attain speed in solving it, the player must view it on the top side of the cube, thus enabling them to plan ahead of time and eliminate any unnecessary moves and rotations. The corner edge positions could have a possible of 41 variations of which can be solved even without using algorithms.
The Orientation of the Last Layer (OLL)
The OLL paves to the last layer to have one color orientation, and it can be done by solving the eight pieces, which are the four corner pieces and four edge pieces. The solving of the OLL requires the use of an algorithm in order to have one look OLL or two-look OLL. Basically, you will have been acquainted with the algorithms in the beginner’s method, and you must attain mastery of the 57 algorithms in order to achieve the one-look OLL or the two-look OLL.
Permutation of the Last Layer (PLL)
There could be a possibility of 21 combinations that can complete and solve the final and fourth step in the Fridrich Method. This logically means that the player must have mastered 21 algorithms in order to have the last layer to be successfully solved. In the beginner’s method, you could already be acquainted to the two algorithms used in these 21 algorithms.
The CFOP Method may seem to be more complicated, intense, and more difficult than the beginner’s method. However, once you get acquainted with it and through constant practice, you will be able to gain mastery of this method that eventually will make you achieve speed in solving the Rubik’s Cube.
The difficulty relies on its unconventional way of solving the Rubik’s Cube. But once mastered, a player may be able to solve it in a span of time of 30/20/10 seconds. This is what this game is all about, which entails persistence, mastery of the patterns, and constant practice. The analytical mind is being developed by carefully studying the method and one of which is the CFOP Method.
