Umm, wow. Before I started I wondered, “how is this enough information to determine both the regions and the digits in them?” And as it slowly resolved, I kept wondering the same thing. How is this happening? It felt like magic. A very satisfying solve.

Clean, beautiful logic on a very sparse grid. I actually gave it 4 stars but I realize I might be in the minority... With so few clues, it's "easier" in the sense that you don't have to wonder where to look.

Superb puzzle with some really rewarding and intricate logic. Completely agree that it's all about asking the right questions - and once you do, it's a beautiful solve.

I solved this the other day and forgot to comment; shame on me for not giving you due cheers earlier! This was a truly brilliant entry in the CC canon. I found the example puzzle to be a useful aid in approaching the main event. Exceptional setting here against what, at first, appears to be an impossibly free rule set. A very narrow solve path, I found, but wholly accessible with some good probing. Truly wonderful. Thank you!

Absolutely brilliant. I had several eureka moments throughout the solve. Very consistent path - that forces you to ask the right question. Bravo!

Exquisite creation! So many different types of questions being featured in the break-in sequence. It keeps around the same difficulty going into the irregular section as well.
Agree that it's not too hard and should be on CTC someday

Absolutely miraculous, oh my lord!
And it's not brutally hard (4¼ for me), therefore really a must-do for CtC.
On a cosmetic note, I think it would look better if the sandwich clues are moved to R0 and perhaps given a circle or a shaded background (more colorblind-friendly).

Genius CC. Thanks.

Can I get a rule clarification? Does cell X+1 after the first border in a row/column with a black clue have to be in a different region, or just NOT in the same region? In C5 of the example the 3rd cell after the border is off the grid and therefore NOT in a different region.

Thanks for pointing out the imprecision in that rule. I've updated it to make clearer that the X-Sum cells can reach the grid edge.

Brilliant construction. Absolutely baffling how it solves with such minimal clues. Some deductions pushed me to my limits, but the solve path is consistently hard and interesting.
