Mostly Harmless
(Eingestellt am 11. April 2026, 05:47 Uhr von AaronH)
Arthur followed Ford's finger, and saw where it was pointing. For a moment it still didn't register, then his mind nearly blew up. "What? Harmless? Is that all it's got to say? Harmless! One word!" - The Hitch Hiker's Guide to the Galaxy
Rules
Normal sudoku rules apply: fill the grid with digits 1–9 so that no digit repeats in any row, column, or 3×3 box.
All variant clues follow their standard meanings; full descriptions are provided below.
- Dynamic Fog: The grid is covered with fog; entering correct digits may clear fog elsewhere, and no guessing is required. Any lines or markings continue and connect beneath fog. Unless revealed, no additional clues should be assumed to exist under the fog.
- Kropki Dots: A black dot indicates one digit is exactly double the other, while a white dot indicates the digits differ by 1.
- X / V Sums: An X between orthogonally adjacent cells indicates the digits sum to 10, and a V indicates the digits sum to 5.
- German Whispers: Along a green line, adjacent digits differ by at least 5.
- Modular Line: Along a teal line, any three adjacent digits must include one digit from each of the modulo‑3 sets {1,4,7}, {2,5,8}, and {3,6,9}.
- Nabner Line: A yellow line cannot contain two digits anywhere on the line that are consecutive.
- Maximum Cells: Cells indicated by greater‑than symbols, must contain a digit greater than all of its orthogonally adjacent neighbours.

indeed, took me a minute to figure out the end as well...
Sure, reading the rules helped, seeing what is indeed missing and such, but it's not as low hanging of a fruit as the rest has been... still a very beautiful puzzle

Not by me. It is a very nice puzzle that needs more solves and has a Hitch Hiker's theme.

Yep, no guessing needed, but I can understand the struggle with the last step. I had to bifurcate a bit to figure out the technique I was missing.

This does solve uniquely without making assumptions on contents of the fog.

11:22 For me. R7C2 and R7C3 are ambigous, there's no hint how they should collapse. Had to guess. The maximum hint showed up too late for me.

This is a great puzzle, the last thing is a little hard to spot but not THAT hard!

This puzzle was mostly harmless. And mostly 1 star difficulty :)

I"m stuck with a few boxes on the left side of the puzzle. Probably something obvious I'm missing. Haven't seen the maximum rule pop up yet.

Thanks for the "standard rules" line, btw

I think this solves fine as it is - I put a hidden comment on my final resolution.
