- Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells.
- All ? clues are positive single-digit integers, which are Numbered Room Sandwich clues.
- Numbered Room Sandwich clues indicate the sum of the digits found in the cells between the Index and Indexed digits of the Numbered Room. The Index and Indexed digits are found in the same region. The sandwich sum cells are collectively found in a single different region.
(Numbered Rooms clues are placed in the seen row, column, or diagonal position indicated by the first seen digit in their respective row, column, or diagonal.)
Here's an example to demonstrate the rules:
Finally managed an empty grid with ambiguous outer clues! Hope you enjoy the puzzle! 😄 - Any feedback or comments welcome!
Solution code: Column 8 (top to bottom) with dashes for region borders. (e.g. 123-4-56-789)

Phenomenal puzzle! Some tough but very fair deductions throughout, and quite amazing that every clue was able to be ambiguous!

Absolutely incredible minimalistic CC !
I didn't think a "?" clues only CC could be smooth, but you did it !
Thanks for setting this puzzle, that never lets the solver feel stuck, there's always a deduction somewhere that pops up !

Very nice ! The later half did not solve as I would have expected it to, so I spent some time trying to disprove something that was actually true... Interactions were well chosen to keep it to a minimum of clues. Thanks.

Very nice. Quite hard, but it flowed alright for me. But then, when half the irregular sudoku bit was done, I completely forgot about the sandwich sums and spent an extra slow hour toiling about. Once I remembered that bit, it solved nicely again :) Thank you Xenonetix!

Brilliant puzzle. Perhaps not the most sensible choice for my first region construction puzzle, but beautiful logic to uncover throughout. And a fantastic set of ideas.
- Always great to jump in the deep end! Thanks for playing this as your first! :) - X
