Congratulations on the solve yesterday, it has been interesting keeping up with your M2M challenge.

Hey Jon — Thanks for following along and for the support.

The Rubik’s Cube challenge is interestingly different to the portrait drawing challenge, for example, in the sense that the method is very well-defined and freely available on the internet. Once you learn the beginner’s Rubik’s Cube method, the trick to getting faster is 1) Understanding the progression of methods, 2) Analyzing your own inefficiencies, 3) Disciplined and deliberate practice.

Here’s a progression that you can follow:

  1. Learn the beginner’s Rubik’s Cube method on YouTube (search for “Rubik’s Cube tutorial”).
  2. Once you are very comfortable with the beginner’s method, learn F2L and the CFOP method. This basically means you will attempt to complete the first two steps of the beginner’s method at the same time.
  3. Once you are comfortable with CFOP and F2L, learn two-step OLL and the 21 PLL algorithms.
  4. Once you learn these, learn all 57 OLL algorithms.
  5. Once you learn all 78 algorithms, learn the ZBLL algorithms, effectively collapsing the last two CFOP steps into one.
  6. More algorithms and practice…

To get sub-20, I only completed this progression up to step 3. All these steps should be highly google-able and well-documented (which should help clarify some of the acronyms)

Hope this helps.
