Thermo Kropki Arrow Sudoku

(Published on 14. February 2021, 14:49 by Lizzy01)

Normal sudoku rules apply. Digits along thermometers increase from the bulb end. Digits along arrows sum to the digit in the circle. White dots are between consecutive digits, black dots are between digits with a 1:2 ratio; the negative constraint applies.

This negative constraint is confusing. A black dot can't be a 1,2 pair because that would have been a white dot?

--No it's standard kropki rules, any pair of cells without a dot can't be consecutive or in a 1:2 ratio, 1 and 2 can be on both black and white dots.

It turns out you can proceed quite far and forget negative constraint, ask me how I know :) Thank you.

Sorry, I wanted to be sure, does the negative constraint apply to just the black dots or to the white dots as well?

Ah, nevermind ... I see that is active in the puzzle and the answer is yes, to both.

Very entertaining puzzle. I like how the rules interact with each other.

One thing... I don't think it's a 3 stars puzzle. I would say it's more of a 2 star, but still lovely.
