9-steps Tutorial: Between Lines
Here is a tutorial sudoku teaching the Between Lines constraint and aimed at first-timers. It is accessible, though not the easiest puzzle. When following the steps, it is build to showcase some common between line logic you will find in almost any between line sudoku there is! However, if you feel like it, or for more experienced solvers, feel free to solve it any way you like, there are no rules! (Except the following...)
Rules: Normal sudoku rules. Cells along lines between two filled circles must have values strictly between those in the circles. NB: Digits may repeat along a line.

Last puzzle in the serie: Anti-knight
Solution code: Column 4, top to bottom

This was way harder than I thought when I started it. But very enjoyable. Thanks!

I like your 9-steps tutorials. Especially in the evening, when my brain doesn't work that well anymore.
