Completely Antiknight Slitherlink
(Published on 4. May 2021, 06:56 by Geoteve)
When I uploaded Antiknight Slitherlink, I got a comment that he or she wonders if an antiknight slitherlink without a red cell(which isn't affected by the antiknight rule) is possible. And this puzzle is a possible case I've found. I wonder if there's more, but I don't think I will try finding more.
Rules
1. Fill 0~3 in every cell of the grid. Cells separated by a chess knight's move cannot contain the same digit.
2. Draw a single continuous loop by connecting neighboring dots along the dotted lines. The numbers indicate how many edges of a cell are used for the loop. The loop may not touch or cross itself, and it doesn't need to touch all of the dots.
You can try this puzzle on Penpa+.
Solution code: Digits in Column 4 and 5

I really liked the idea of using the anti-knight constraint with slitherlink. Hopefully other setters (or you) do discover another one :-)

Nice puzzle! Just some quick remarks regarding translation into german:
- "rote Blutkörperchen" should be "rote Zellen" (and the first word in the bracket should be "die", not "der", and the last should be "sind" instead of "ist")
- "eines Schachritters" should better be "eines Schachspringers"
- It would probably be better to remove the "möglicherweise" :)
