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.
Thermo: Digits along a thermometer must increase from the bulb to the tip.
Killer: Digits do not repeat in cages, and sum to the small clue in the top left corner if given.
Each region takes at most 1 cell in each cage. In addition, digits in a caged cell indicate the total number of visible cells from the same region vertically and horizontally, including itself, where other regions block view.
Solution code: Column 7, with a - between each region border
