Let me give some backstory before I talk about the main thing
In speedcubing, the first method you learn is the beginners method. Once you learn that and you wanna get faster, you would learn one of three main methods:
CFOP, roux, and ZZ.
CFOP and ZZ both are solving the cubes differently, but they both have a similar method to solve the last step. It is way more complicated and should only be learnt if you wanna know more ways to solve the cube faster.
It’s called ZBLL.
Let’s take a look at CFOP. 4 steps. Solve the cross, finish the first two layers, make the top face the same color, and solve the rest of the cube.
The last two steps have around 80 algorithms. Some as short as a couple moves and some as high as 20+. It took me 1 month to learn it all.
ZBLL combines the last two steps, into one.
It is 493 algorithms, all of them very long. And yet some cubes have learnt it all. Not just learning the notation, but also recognition(using a certain alg for that case.)
I have no idea how they do this without forgetting at least some.
…
and yet even fewer cubers have learnt a better method.
ZB
Which combines the method I just talked about, with another method called ZBLS.
ZB has 840 algorithms, almost double the previous.
It amazes me how some people have that good of memory plus muscle memory.
And while there are some people that have memorized tens of thousands of digits of pi, I find this more impressive because you have to do recognition plus remembering the algorithm.
