Chaos Construction: Divide the grid into nine orthogonally connected nine-cell regions, and place the digits 1 to 9 once in each row, column, and region.
Top Right Boi: In each region, the rightmost cell of its topmost row is a doubler. Value of a doubler is twice its digit. Digits cannot repeat in Top Right Bois.
Bottom Left Boi: In each region, the leftmost cell of its bottommost row is a nullifier. Value of a nullifier is 0. Digits cannot repeat in Bottom Left Bois.
White Region Dots: Cells joined by a white dot belong to the same region and contain consecutive values.
Black Region Dots: Cells joined by a black dot belong to different regions and contain values where one is double the other.
Arrow: Values along an arrow sum to the value in the attached circle.
