Modular Fog
(Eingestellt am 13. Mai 2025, 07:53 Uhr von kyuquu)
This is my first attempt at creating a fog puzzle. Please enjoy, and feel free to leave feedback!
RULES:
Normal sudoku rules apply.
Dynamic Fog: The grid is covered in fog, which will gradually clear as correct digits are placed. No guessing is required.
Modular Lines: Any three adjacent digits along a teal line have different residues modulo 3.
Partial Kropki: Digits separated by a white kropki dot are consecutive. Digits separated by a black kropki dot are in a 1:2 ratio. Not all possible kropki dots are given.
Killer Cages: Digits in a cage do not repeat and sum to the value in the top left corner.
XV Pairs: Digits separated by a V sum to 5. Digits separated by an X sum to 10.
Lösungscode: Row 9 (left to right)

It's only a 1 star for solvers that are happy go lucky making assumptions, it's definitely not a 1 star to solve logically.

Very fun, and perfect 1 star difficulty (even if I kept making mistakes).
Thank you @xrrx for sharing the modulo 3 combinations

Great puzzle! Very intricate logic for a 1* puzzle, but enjoyable nonetheless!

Well done!

I did not need to assume there was one modular line to solve this puzzle

Thank you @xrrx for defining the modulo 3 rule.

@VitP I had to make that assumption as well.

Solvable without additional rules.
Fun puzzle, thanks!

Added dynamic fog to the rules (oops!)

Very nice fun puzzle.

@VitP, I solved it without assuming anything that wasn't specifically mentioned in the rules.

Very enjoyable solve! It wasn't super hard, but it was well designed and aesthetically pleasing. Well done!

Nice puzzle. Smooth solve with rules as is.

Puzzle solves very smoothly without any need to change rules.

do you mean for there to be ONE modular line, having SIMPLE geometry?
because that is NOT what the rules say, and without that assumption, the puzzle appears to be insoluble.
@VitP I suppose it wouldn't hurt to mention that the line can only travel in a straight line orthogonally or diagonally, but the puzzle is indeed solvable with this in mind, even if you allow that there could be multiple lines.

Just for the others in case they dont know: residuals of modulo 3 are these combinations 147, 258, 369
