Dutch v. German Battle
(Published on 3. October 2025, 21:04 by certifiedpaintfreak)
Normal Sudoku rules apply.
Fog covers the grid. A correct input will clear the fog in the surrounding cells. No guessing required.
Adjacent digits on German Whisper (green) lines must differ by at least 5.
Adjacent digits on Dutch Whisper (orange) lines must differ by at least 4.
Box borders divide blue line segments into the same sum. There is only ONE blue line.
Only the number 5 has an anti-knight constraint ie all 5's cannot be a knight's move away from any other 5.
Digits increase from a thermometer's bulb.
Digits on arrows sum to the circle attached to them.
Digits separated by x's add to 10.
Digits separated by white dots are consecutive.
Digits separated by black dots have a 1:2 ratio.
Solution code: digit in row 1 column 1

met the same problem.
without assuming the thermometer in b5 , nothing can be deduced

Yep, same issue. I was unable to solve this without making assumptions about the thermometer in box 5.

Is it just me or is it required to know that the thermos are single-branch, single bulb? Because I couldn't solve box 5 without that assumption.
For example when r6c5 was still covered, that square could have been a bulb with two branches going out from it, and there seemed to be no way to progress without knowing that a bulb couldn't be there. Could be wrong, just don't know whether to submit a solution code or if I need to put more work into it.

One of the more interesting break-ins for a puzzle of this difficulty.

Good fun. Just a 1* difficulty though.

Very nice puzzle. The solution code was actually a second small puzzle. ;D
