The methods I described in my previous posts can solve a cube, however they are not close to being very efficient. Therefore, I am outlining a few more efficient methods for each cube in this post, starting with the 2×2.

## 2X2

A good method for 2×2 is the Ortega method. It is a very useful method and can easily take your times down to less than 5 seconds. This method is done by first solving a face, then solving the opposite face, and finally permuting both layers. There are 13 algorithms to learn in total, some of which you will already know, to solve using Ortega.

A good place to learn this method is Cyotheking’s website.

Pros- Easy to learn, can get quite fast.

Cons-To get world class, this method isn’t sufficient.

Another good method for 2×2 is called CLL. It is a very simple method used by world class solvers. It is done by solving a layer, and then using one algorithm to solve the last layer. There are many extensions of this method which can be used along with CLL to get better times.

A good place to learn this is Cyotheking’s website, which also has the extensions I mentioned earlier.

Pros- World class times are possible

Cons- Lots of algorithms are needed, particularly if you want to learn the extensions.

**3X3**

Moving on to 3×3, there are lots of methods available for use in advanced solving. The most popular is the CFOP method, also known as the Fridrich method as it was proposed in the 1980’s by Jessica Fridrich. This method can be called a more efficient form of the beginners method. The steps to it are (1) Solving the cross, (2) Solving the first two layers, (3) Orienting the last layer and (4) Permuting the last layer to solve the cube.

Pros- Simple, somewhat intuitive

Cons- Lots of algorithms to learn

Another method for 3×3 is the Roux method, proposed by Frenchman Gilles Roux. His method is where you build two 1x1x2 blocks on opposite sides, solve the last layer corners, orient the last 6 edges, and finally solve the rest with one algorithm.

Pros- Very intuitive, few algorithms

Cons- Hard to understand at first

## Pyraminx

For Pyraminx, the method I have described earlier is quite good, if the top 3 edges can be done efficiently. Another method is LBL, or Layer by Layer. It is a very fast method and can be used to achieve times of 5-6 seconds. It is done by building the bottom layer, then finishing the top with one algorithm. There are 5 algorithms to learn.
