The rules:

Normal sudoku rules DO NOT apply.

Normal Schrodinger Sudoku rules apply. Fill the grid with the digits 0-9 such that no digit repeats in a row, column, or box.

S-cells: In each row, column, and box there is exactly one S-cell. S-cells contain two digits instead of one, and their value for the purpose of other clues is the sum of those digits.

Doublers: One cell in each row, column and box is a doubler. For the purpose of other clues, the cell's value is double the digit (or digits) in the box. Each digit from 0-9 appears exactly once in a doubler cell.

Region sum lines: On blue lines, the sum of values on the line is equal in each region the line appears in. Different lines may have different sums.

Killer cages: Digits do not repeat in cages (though values may repeat) and values sum to the total in the top left corner of each cage.

Kropki: Values in cells separated by a black dot have a 2:1 ratio. Not all dots are necessarily given.

I want to start using a sig, just to put that quote there. :D Glad you enjoyed it.

It was a tough one for sure and took me quite some time but I never felt stuck. Great challenge, very satisfying all the way through.

Quite difficult, but well worth it, brilliant use of combining both modifier cells to create new logic. Thanks for sharing!
