Anti-knight Anti-king: The Pattern
(Published on 27. November 2021, 03:15 by DiMono)
This is a puzzle with two solution paths. If you approach it from scratch, there is a difficult but logical path to the end that I think is rather interesting. If you know things about anti-king anti-knight sudoku grids, it can be finished in about two minutes. But where's the fun in that?
Standard sudoku rules apply.
Anti-king: diagonally adjacent cells may not contain the same digit.
Anti-knight: cells a chess knight's move away from each other may not contain the same digit.
Solve on f-puzzles
Solve on CTC

Hmm, after taking the difficult path I now seem to know things about anti-king anti-knight sudokus. Nice! I wonder if it can be proven that this holds for all anti-king anti-knights?
@Gullie: Yes, it is true for all anti-king anti-knight sudoku. I've posted an in-depth proof of one of the properties of these puzzles in the #theory-and-programming channel of the Cracking the Cryptic discord server.
