Great puzzle! Very surprised it only has three stars for difficulty. I must have missed an important inference because this took a LOT of difficult inferences to finally solve.

Excellent puzzle. The big break took 80% of the time but was well worth it. An original use of if/thens

A few backtracks caused by my usual hasty conclusions, but a very pretty puzzle which I enjoyed solving, thank you.

Absolutely loved this! Lots of logic switching, and every rule is relevant multiple times. Thanks!

German correction

I would suggest to write "Ziffer" instead of "Finger" in the German description. The Google translator is funny at times.
Btw, I believe the translator of deepl.com is a good bit better.
@Phistomefel: Thank you, I've updated the German with Ziffer. I plugged the English text of this puzzle into DeepL and it lost part of the "or any other snake" emphasis, so I think I'll keep the Google translation on this puzzle, but I will keep DeepL in mind for future puzzles.

Finger ??? (schlechte Übersetzung, der englische Text ist da klarer (es ist wohl gemeint, dass die Zahl in der zentralen Zelle in keiner Schlange vorkommen darf)
@SKORP17: Ja, das ist richtig. Was ist ein besserer Weg, es für die Regeln zu übersetzen?
