I'm with TVDK, definitely found this to be a hard puzzle. Fantastic logic all the way through though. Thank you!

What a gorgeous RSL sudoku with such elegant logic. Definitely more like 4* for difficulty though.

Beautiful puzzle. I found it quite difficult, but I also am just starting to do RSL more, and I had to learn several new techniques to solve this one. Very very fun, thank you!

Over an hour here as well, but great puzzle. Got a few digits and then basically pencilmarked the entire grid. Got a bit frustrated but of course it were the last 3 cells I didn't pencilmark that solved the entire puzzle.

Very nice construction, for a long time it felt like it was just one deduction away from giving in but there was always more to find. Had a great time. Thanks!

Wow, what a puzzle! I found it much harder than 3 stars, but it was so exciting. Even when I believed I could not find anything anymore, it did not let me go. And, in hindsight, I am very glad I did not gave up too early. Thank you for this amazing construction, NicoD!
