Uniqueness
(Published on 19. June 2025, 03:32 by chrisjnap)
Normal sudoku rules apply.
Digits in killer cages must not repeat and must sum to the number in the top left of the cage, if given.
Cells with grey squares in them contain even digits.
Cells with grey circles in them contain odd digits.
Cells joined by a white dot must have a difference of 1.
Cells joined by a black dot must be in a 1:2 ratio.
Not all dots are given.
Each constraint type may contain no repeated digits anywhere in the puzzle.
Solution code: Enter column 4

Absolutely fantastic setting! I made it much harder by ignoring a digit in a circle i got early on, but still managed 10:09. Really excellent setting!

I’d never seen uniqueness applied to kropki dots before and it was awesome!! Thank you :)

This was a very nice puzzle. First time seen the uniqueness on an open puzzle like that. Great interactions. Very clever setting thx.
