Chaos Construction: Digits are not repeated in rows, columns, or regions. The grid is divided into nine hidden regions, each consisting of orthogonally connected cells containing the digits 1-9.
CC Cages: Digits in a cage sum to the number in the top-left of the cage and cannot repeat. Within each cage, all digits of the same parity share the same region, and digits of opposite parities cannot share a region.
CC Summit Lines: Digits along a blue line must be ascending or descending, with 1 and 9 reversing the ascension/descension. Blue lines consist of two regions. Low digits (1, 2, 3, 4) share the same region and high digits (6, 7, 8, 9) share the other region. A 5 can belong to either.
