Stroll in the fog
(Published on 22. January 2025, 20:26 by maxlamenace)
For my second puzzle, I played with fog to add simple logic to some classic variants (arrows, renban, kropki). I hope you enjoy it!
Rules:- Normal sudoku rules apply.
- Fog: The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells.
- Arrows: Digits along an arrow must sum to the digit in that arrow's circle.
- Renban: Digits on a purple line must be a set of consecutive, non-repeating digits (in any order). Lines do not cross or branch.
- Kropki: Digits on a white dot are consecutive.
Solution code: Row 3 (9 digits)

Added a quick note to specify that renban lines do not cross or branch.

I rated this 2/5 difficulty.
This is a great FoW sudoku. I agree with @dingledork and @VitP ghat this puzzle is HIGHLY underrated. Really liked the logic around the bottom-right-most arrow, as it was totally not what I was expecting!
I really liked the logic you packed into this puzzle, and it was super fun to solve. So many great ideas that are approachable enough for the general community, but clever enough to be very entertaining. The puzzle had several 'phases' for me, and IMO the hardest part was the final disambiguation of the top-most renban.
Great puzzle, definitely worth giving it a solve!

in fog puzzles, you need to specify how line crossings and branchings are treated. generally, they are disallowed, but that is not guaranteed.
notwithstanding the above, this is a properly constructed puzzle, and therefore desreves a rating of 90% or more.

I’ll never understand the ratings on this site. This is a great fog puzzle - not difficult, but with some VERY clever logic to be discovered mid-solve.

This is an outstanding, yet easy puzzle. I loved the interaction of the clues. It was never too obvious, but hat always a logical flow. Thanks for sharing.
