9-steps Tutorial: XV
Here is a tutorial sudoku teaching the XV 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 XV logic you will find in almost any XV 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 these ones...)
Rules: Normal sudoku rules. Two cells separated by an X must sum to 10. Two cells separated by an V must sum to 5.

Last puzzle in the serie: German Whispers
Solution code: Bottom row, left to right

@Snaques: here's an anti-knight tutorial. I wouldn't say it's a 1-star puzzle, but it does explore the constraint from several viewpoints. https://f-puzzles.com/?id=yk7ysq96

Thanks for the great feedback, it really is a joy to read :)
About the anti-knight tuto, I thought about it, but it is quiet hard to set, since it quickly goes all over the place! I'll try for the fans ;)
