A Knightly Sword

(Published on 20. April 2021, 23:16 by tsc)

❶ Standard Irregular Sudoku rules apply
Kropki Pairs: white dots contain consecutive digits, black dots contain digits with a 1:2 ratio. No negative constraints, so not all dots are given
Knightly sword rules: The grey cells on the diagonal form a (scattered) region. So on the diagonal all digits from 1-9 must appear exactly once. All cells a knight's move apart from cells on the sword (and only the sword) must not contain the same digit

Puzzle: f-puzzles | penpa

Triangles (half white half grey) are only for aesthetics.

Solution code: column 3 (top down)

Ah, I see. I'll try the puzzle again with the correct understanding now!

[tsc] Thanks so much for trying again, hope it was worth it

I was trying to solve the puzzle with the assumption that two sword cells would also have a knight restriction (since one of them is knight's move apart from the cell on the sword), but the puzzle broke twice. Unless I was making some other error repeatedly, that means the restriction is only between a sword cell and a non-sword cell. If that is the case, a clearer way to state the rules could be "A cell on the sword and a cell not on the sword that are knight's move away must not contain the same digit".

[tsc] I am so sorry for the confusion. The "sword" consist of the diagonal only! I should have made this clearer in the rules
