Killer: Digits do not repeat in cages, and sum to the digit in the top left corner.
Chaos Construction: Divide the grid into regions, each consisting of nine orthogonally connected cells. Each row, column and region contain the digits 1-9 once each.
The smallest digit in each cage counts the number of different regions that enter that cage.
Solution code: Column 8

Wonderful! That was a joy to solve. Right at the limit of difficulty for me, and so satisfying when I made it all the way through.

Wish there were more CC puzzles like this that aren't 4-5 star difficulty. This was much more approachable than many CC puzzles on this site but was still fantastic. Well done.

Really nice puzzle, I found it flowed really nicely once I actually realised how the constraint impacted the cages. Thanks again!
