Digits are not repeated in rows, columns, or hidden regions.

Chaos Construction: The grid is divided into nine hidden, orthogonally connected zones containing nine unique digits (replacing nine 3x3 squares). A digit with an arrow indicates the distance to the edge of its zone in the direction of the arrow (not counting the cell itself). Digits in a circle indicate how many hidden zones are in its row.

Dutch Whispers: Digits along an orange line have a difference of at least 4.
