Spellbound (Fog)

(Published on 10. March 2026, 09:07 by Liamhere)

Dynamic Fog: Placing correct digits may clear up fog somewhere in the grid. No guessing required.

Normal Sudoku rules apply. Place the digits such that every row, column and 3 by 3 box contains the digits from 1-9 only once.

Kropki Dots: Digits separated by a black dot has a 1:2 ratio. (One is double the other)

Green Whispers Line: Adjacent Digits along a green whispers line differs by at least 5.

Orange Lines: Digits on the same orange line has the same number of letters when spelled. (For example, 4 and 9 may lie on the same orange line since both FOUR and NINE have four letters)

Solve on Sudokupad.

Solution code: Digits on column 5. (From top to bottom)

Really enjoyed this one a lot. It was a solid 3* for me though. Maybe I’m missing something.

not easy to see for color blind people.

The orange line gives interesting interactions with the whispers. Once the rules are interpreted, everything becomes approachable.

Initally I was a bit worried about having to track the numbers that work with each other, but the puzzle helped with that so that it never became an issue.

Took some time to finish the puzzle so I gave it 2/5 in difficulty. Maybe I missed something there.
