Unique Under the Fog 5.0
(Published on 14. May 2025, 13:39 by Visumation)
Rules:
Normal sudoku rules apply.
Digits on an arrow sum to the digit in that arrows circle.
Neighbouring digits on a green German Whisper must have a difference of at least 5. (GW)
Digits on a purple Renban line for a non-repeating set of consecutive digits. (RB) (Z)
Grey Ten-lines must be divided into non-overlapping segments that all sum to 10. (T)
Digits separated by a black dot are in a 1:2 ratio.
Digits cannot repeat on the positive diagonal.
Digit cannot repeat on the negative diagonal.
Digits cannot repeat in cells with blue squares.
Cells with a grey circle contain odd digits.
Each constraint type may contain no repeated digits anywhere in this puzzle. Eg. If one renban line contains a 5, then no other renban line may contain a 5.
Additionally the grid is partially covered in fog. Placing a correct digit may clear fog in somewhere in the grid.
Solution code: Row 3

Amazing puzzle!
The blue squares were a bit annoying as I like to mark stuff with colours. Maybe there could be an additional non-color mark (also for accessibility) like a dot in the corner or a background pattern instead of a flat colour?

This one was tough but fair. Loved it, the break in especially. Thanks.

The break-in and the endgame parts are very beautiful,but that one step in the middle was not very friendly you know,but nevertheless really liked the puzzle,so thank you very much.
Yeah. I was debating with myself if I should leave that step in. I decided to leave it. Maybe that was the wrong decision…;) Thanks for solving and commenting. /vis

Perhaps it's because I've solved too many puzzles. I think this break is quite obvious and probably not as difficult as commonly recognized.
Yeah. I think it is very possible to have seen a trick similar to this before, if you solve a lot. Thanks. /vis
