Horse Whispers
(Published on 2. November 2026, 19:51 by gk122)
Normal Sudoku rules apply: place a digit from 1 to 9 in every empty cell so that each row, each column and each 3x3 box contains every digit exactly once.
- Anti-Knight: No two digits separated by a chess knight's move may be the same.
- German Whispers: Adjacent digits along a green line must differ by at least 5.
- Thermometers: Digits strictly increase from the bulb towards the tip.
- Odd Digits: Digits in cells with circles must be odd (the bulb of the thermometer does not count as a circle).
- Even Digits: Digits in cells with squares must be even.
Solution code: Column 9

Clarified rules and fixed error in rules on sudokupad.

I disagree with paintspotinfez regarding the bulb.
but he's right in pointing out the "unclear rules" on sudokupad.
Anyways, very nice puzzle, I had to stay ambivalent [high/low] until the very end.
I cannot remember having solved any german whispers puzzle that I haven't placed a single digit until the puzzle was entirely solved and I only had to replace my colours with digits.
Very satisfying solve!
thank you very much for sharing.

I feel like the rules should specify whether or not the round bulb of a thermometer also counts as a circle or not.
(Oh also, while the Logic-Masters version of the rules mention circles and squares, the rules on Sudokupad itself currently say "Digits in marked [odd/even] cells must be [odd/even]" without clarifying which shape is which)

I'm new to setting and probably a bit blind to the difficulty (I know exactly what to do so it must be easy!)
Adjusting the difficulty after your feedback, will also add a hidden comment on the intended break-in

I echo the other comments. Loved the puzzle, but the break took me nearly an hour. Is there something we missed or was your 1-star rating trolling us!

Very nice puzzle, but far more difficult than 1 star, rather closer to 3 stars.

If this is a 1 star, I am _very much_ missing something. Struggling with it for two hours in two days.
