Variant Sudoku 101: German Whispers
(Eingestellt am 17. Dezember 2025, 07:59 Uhr von PhoenixAki)
- Normal sudoku rules apply. Place the digits 1-9 in each row, column, and 3x3 box without repetition.
- German Whispers: Adjacent digits on a green line must have a difference of at least 5.
To increase accessibility to my puzzles, I include hints in my LMD posts and also post solution videos on my YouTube channel. I hope these help you solve the puzzles if you are struggling :)
Hint 1: There's 2 important freebie bits of info about German whispers. First, can 5 ever go on one? Second, what does that mean about how the lows and high digits must be dispersed on a line?
Hint 2: Another good piece of info to realize is that 4 and 6 are very hard to place onto long German whisper lines. 4 must be paired with 9, and 6 must be paired with 1. Apply that info to boxes 1 and 9 and pencilmark the results as far as you can.
Hint 3: Column 2 is special once you work out box 1's digits. Where can 4 and 6 go in the column, and what digits does that leave left over? Doing all that is enough to resolve box 9.
Hint 4: Where can 3 go in row 8?
Hint 5: Continue to pencilmark the lines as you go, remembering about lows and highs and 4's and 6's. The most important observation involves where 4 can go in row 2. That is enough to resolve a lot of things and kickstart the end of the puzzle.
Lösungscode: Box 5 in normal reading order (left to right, top to bottom). 9 digits.

Added hints after learning recently how to do that in HTML. Wish I knew this a few weeks ago when I went over all my posts...oh well.

Updated post as part of an effort to improve consistency of rule phrasing and post layout across all my puzzles.

This puzzle does a fantastic job of being easy without being boring (which is something I feel like German whispers can be at risk of more than most constraints). I feel like this would be a lovely introduction to German whispers for someone who hasn't encountered them before, while still being plenty of fun for someone like me who has loved German whispers for a long time!
