Play in Sudokupad

Here is a type of deconstruction puzzle with four sudokus to solve. Color the 3x3 regions in the grid so there is one Pink Arrow Sudoku, one Green XV Pair Sudoku, one Blue White Kropki Dot Sudoku, and one Orange Black Kropki Dot sudoku. Place the digits 1-9 in each region. Digits may not repeat in a row, column or diagonal of the same color sudoku.

Note: Row, column, and diagonal rules apply only to each color sudoku. Digits will repeat in the 18x18 grid rows, columns and diagonals.

Cages indicate orthogonally connected identical digits. Obviously, cages can only occur on borders of two or more regions from different colored sudokus. Negative Constraint: All possible cages are given.

Digits on an arrow sum to the number in the attached circle (Pink Sudoku).

Pairs of cells connected by an X sum to 10. Pairs of cells connected by a V sum to 5. Negative constraint: All XV pairs in the Green Sudoku regions are given.

White dots connect consecutive digits. Negative constraint: All white dots in the Blue Sudoku regions are given.

Black dots connect cells with a 2:1 ratio. Negative constraint: All black dots in the Orange Sudoku regions are given.
