Counting Constraints

(Eingestellt am 22. Juli 2025, 16:25 Uhr von etoler)

Normal Sudoku rules apply.

Dynamic fog: The grid is partially covered in fog. Correctly placing digits may clear fog somewhere in the puzzle. Correct digits do not necessarily clear fog from their own cells.

Counting constraints: A digit on a constraint indicates the total number of times that digit appears on any of the constraints below. No cell contains more than one constraint.

German whispers: Adjacent digits along a green line must have a difference of at least 5.

Dutch whispers: Adjacent digits along an orange line must have a difference of at least 4.

Nabner lines: No two digits on a yellow line may be the same or consecutive.

Renban lines: Pink lines are filled with a consecutive set of non-repeating digits.

Counting circles: A digit in a black-outlined counting circle indicates the number of times that digit appears in a counting circle.

Odd circles: A digit in a gray circle must be odd.

Kropki: Digits separated by a black dot have a ratio of 1:2 (i.e. one is double the other).

That was very cool. Loved it, but at the same time a bit scary being able placing so many digits that don't clear any fog. Thanks!

Gorgeous! To find the break-in wasn’t easy at all. Needed one hour, but then it was a nice trip along the path. Thank you very much for creating and sharing this beauty.

That was fun! A lot to unpack at first, but when you start to break it down it get's smoother and smoother.

Thank you for this nice puzzle, etoler! It was great fun to figure out the counting. I had one slight problem/insecurity when starting out: I was unsure if all the constraints were counting together or if each constraint counted on their own (a 6 on a GW meant there would be exactly six 6s on GW lines). I don't know if I am the only one here, but if not, it might be worth emphasizing in the rules that ALL constraints count together. Thanks again for setting and sharing this treat!

Glad you enjoyed it! One person got caught on this in testing but said they worked it out pretty quickly, so I left it alone for brevity. Without getting spoiler-y, you could prove that a per-constraint version wouldn't work based on the starting grid, but since you're the second person to bring it up, I decided to go ahead and tweak the rules. Let me know if you think this works or if I can adjust it some other way!
