German Shout 2
(Published on 16. August 2022, 03:28 by meowzzz)
Previous puzzle: German Shout
Rules
- Normal sudoku rules apply.
- German whispers rules apply.
- Digits on a green line must differ by at least 5.
- Digits may repeat on this green line, if allowed by other rules.
- German shout (negative constraint of German whisper) apply.
- Digits that are orthogonally connected must not differ by at least 5. (Example: 12,46,15,89 are valid. 16,17,18,19 are not valid).
- Negative constraint does not apply to diagonally connected digits.
F-Puzzle
Fun fact, the negative constraint can fill up to 6 rows max, wrote a little program to check.
Bonus, in theory (probably not human solvable), if you only have the first row of this puzzle there seems to be a single unique solution from it. I couldn't do it myself but if anyone is crazy enough to try :)
Solution code: Row 8 followed by column 3 (no spaces and no commas)

Very nice ruleset, strange and mind-bending at first glance but beautiful once understood...

This is my first try at these rules. Really enjoyed it. Once I got my head around what digits can or can't go together it wasn't that hard anymore.

Nice puzzle!
One suggestion; the rule "Digits may repeat on this green line" should be removed as it is false.
