When following the steps, it is build to showcase some common renban logic you will find in almost any renban 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!
Rules: Normal sudoku rules. Digits along each renban line must be a set of consecutive digits in any order, and must not repeat.

Terrific introduction to renban in all of it's forms, I liked how the different lines showcased very different deductions all along the solving path.
