The Helpful Quad
(Eingestellt am 21. April 2025, 03:57 Uhr von Belamis)
Sudoku: Normal Sudoku rules apply.
Roman Numerals: Digits separated by an X sum to 10.
Renban: Purple lines contain a non-repeating set of consecutive digits in any order.
Killer: Digits do not repeat in cages, and sum to the small clue in the top left corner if given.
Quadruples: Every digit in a circle has to be assigned to one of the surrounding cells.
German Whispers: Along green lines, digits must differ from their neighbors by at least 5.
Constraint Regions: Each constraint type may contain no repeated digits anywhere in the puzzle. E.g. ALL cells connected by an X must contain no repeated digits, ALL cells around quad clues must contain no repeated digits etc.

The break-in is hard to find, but once you found it, the puzzle is ~1* ...

Took me forever to find the (relatively easy break-in)
Loved the non-conventional clues.

Wow that was a tough one for me, easily 4 stars! I really liked the logic with the whisper lines and x's. But the helpful quad and renbans weren't being very helpful to me personally

Brilliant!! Felt like I'd really solved something without getting too stuck

Great puzzle, I espacially enjoyed the importance of box 9.

The break in logic was very nice, smooth sailing after that. Great construction!

What a fun puzzle! The break in was, in my opinion, a bit tougher than 2* but then it starts to resolve soon after.
I loved this puzzle!

Lovely puzzle, but to me the break in was neither obvious nor easy, but once I found it, everything went fairly smooth and easily.
Thanks for setting & sharing!
