3 Vs: Verschiedenheit von Vier
(Published on 11. April 2026, 12:39 by gadgetgreen)
Inspired by the beautiful "XOV" series from The Bard.
Modified Sudoku rules apply: Place the digits 0-9 in each row, column, and box. However, there will be one digit in each that does not fit. This digit can vary between rows, columns, and boxes and needs to be determined by the solver.
XV: Digits separated by an X sum to 10, those separated by a V sum to 5. All Xs and Vs have been given.
Dutch whisper: The difference between two adjacent digits on an orange line is at least 4.
Solution code: Row 5

dutch whispers are my personal nightmare (I struggle a lot with the flipping five) and extended digits do NOT help ...
it's a nightmare to scan for me (had to start with the wort possible pencilmarking [fill all with 0-9] and then reduce.
really nice series, but the next dutch whisper in this series will be skipped ;-)

Thanks for you patience! ... unfortunately there will be a dutch whisper in the future, but it will be different and more approachable in a way. Please give it a try :)

Great job!! A couple tricky spots if you are not paying full attention.

Oh, my... I have forgotten about the negative constraint too, and spent hours on trying and backtracking. Have filled about 60% of grid though. After the hint, it took a minute to finish.
I'm still laughing at myself. It was great, thanks.

I don't think that this has a unique solution.
For instance, row 7 col 5 can easily both the digits that are not in the row or column otherwise.
I did cheat with the solution check on Sudokupad either way. But there seems to be something off with the puzzle.

Maybe you forgot about the negative constrain for the Xs and Vs? Have a second look (:

Update: Yeah, I totally did miss that all Xs and Vs are given. My bad.
