How ZBLL training works
What ZBLL is
ZBLL solves the whole last layer in one algorithm when the last layer edges are already oriented, so it replaces OLL and PLL. It has 493 cases, which is why it is split into sets.
How the drill works
Pick the sets you are learning and leave the rest out, then choose an algorithm mode and add criteria such as a time limit. A connected smart cube times recognition and execution.
How to practice here
Work through one set at a time and add the next once the first stops slowing you down. Adaptive mode, a Pro feature, keeps you on your weakest cases.
Look up the ZBLL algorithms in the library
How many ZBLL algorithms are there?
493 cases. You do not need them all at once: pick a set, learn it and add the next.
What do I need to know before ZBLL?
ZBLL only applies when the last layer edges are oriented, so it comes after you can control edge orientation. Most cubers also know full OLL and PLL first.
Do I need a smart cube to use the trainer?
No. A smart cube is optional. When connected, it adds separate recognition and execution times.
Where do I find the algorithms?
Every case has a diagram and algorithms in the ZBLL algorithm library, linked above. Use the trainer to drill the sets you pick.
