Swords in the Fog

(Published on 25. April 2025, 14:50 by Br1312te)

Solve on Sudokupad. The puzzle can only be solved online due to the fog mechanic.

Rules:

Place the digits 1-9 in every row, column and box.

German Whisper Lines: two cells connected by a green line must have a difference of at least 5.

Dutch Whisper Lines: two cells connected by an orange line must have a difference of at least 4.

Kropki Dots: digits connected by a white dot are consecutive. Digits connected by a black dot are in a 1:2 ratio.

Dynamic Fog: the grid is partially covered in fog. Placing correct digits will clear the fog of that cell. Key deductions might clear more fog. No guessing is required.

Love, Brigitte

Solution code: Row 1 from left to right (9 digits in total)

I rated this 2/5 difficulty.

Great dFoW puzzle! The whole puzzle was nicely put together, and there were several interesting ideas throughout the solve.

I think 2* is a fair difficulty rating. The puzzle was quite approachable, but there some tricky ideas that were probably too difficult for a 1*. I thought the final step/disambiguation was the hardest step (not too hard, but still nonobvious sudoku technique(s)).

My favorite part(s) of the puzzle was probably the first few steps of the break-in. The interaction between the whisper lines was cool, and the fog worked nicely alongside the puzzle logic.

Thanks for sharing!
