Idk if it's because I'm not very familiar with the global entropy constraint but this one was personally easier than Entropy Quilt. Very nice puzzle

Thank you for your reply, Raumplaner. I think I sort of know what you are hinting at. I noticed a little set equivalence forcing a small digit into one cell that was disambiguating the central (diagonal) entropy line. As I do not want to spoiler anybody, I leave the comment as vague as that.
Does that fit with your "hidden line"-concept?

No, i was refering to entropic logic. But interesting to know. (Raumplaner)

Thank you very much. There are some 'hidden' lines in this puzzle that help with the solve if you notice them. (Raumplaner)
