Kropki Chaos
(Published on 23. January 2022, 04:19 by mathpesto)
I've really enjoyed solving chaos construction sudokus recently and wanted to try setting my own for the first time. It was a real challenge, but I'm pleased with the result and I hope you enjoy it! If you're feeling stuck, post a hidden message or find me on Discord. Comments and ratings are much appreciated, and please be sure to check out my other puzzles here.
Rules:
Each row, column, and region must contain the digits 1–9 exactly once. Regions must be determined.
A white dot between cells indicates that they are in the same region and their digits are consecutive.
A black dot between cells indicates that they are in different regions and their digits are in a 1:2 ratio.
Not all dots are necessarily given.
Solve on Penpa+ (Thanks SudokuExplorer!)
Puzzle:
Solution code: Enter columns 7 and 8 (18 digits, no spaces)

Oh awesome to see this kropki rule percolating, I used it in my second puzzle ever! Would it be okay if I did your puzzles on my youtube stream?

I remember wanting to make one with a similar ruleset a while back, but with the negative constraint and kept on breaking it. I'm really pleased you ended up making one. Thanks, it was a joy to solve! :-)

@SudokuExplorer Thanks so much for the Penpa+, I'll add it to the description. Glad to read you enjoyed solving it! I too initially intended for a negative constraint, but couldn't get it to work.
