ZBLS trainer
Drill ZBLS: insert the last F2L pair and orient the last layer edges in a single algorithm.

How ZBLS training works
What ZBLS is
ZBLS inserts the last F2L pair and orients the last layer edges in a single algorithm, so the last layer arrives with its edges oriented. It is the step before ZBLL.
How the drill works
Select the cases you want to learn, choose an algorithm mode and add criteria such as a time limit. A connected smart cube shows your recognition and execution times for each case. Cases are grouped so you can work on a few at a time.
How to practice here
Take one group at a time and drill it until you start without hesitating, then add the next. Adaptive mode, a Pro feature, keeps you on your weakest cases.

What is the difference between ZBLS and F2L?
F2L inserts the last pair and leaves the last layer edges as they are. ZBLS inserts the same pair and orients the edges at the same time.
Do I need ZBLS to use ZBLL?
ZBLL needs oriented last layer edges, and ZBLS is one way to get them.
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 ZBLS algorithm library, linked above. Use the trainer to drill the ones you pick.
