Rules
Normal sudoku rules apply.
Within a cage, digits must not repeat and their values sum to the small number in the top left corner.
There are nine nullifier cells in the grid, one in every row, column and box. Each digit from 1-9 appears in a nullifier cell exactly once.
The value of every cell that orthogonally touches a nullifier cell is equal to 0.
A nullifier cell's value is equal to its digit.
Solution code: Row 2

Before reading the rules i glanced at the board image, did a double take seeing a 5-cell "3" and a "0" cage, thought "this is ludicrous... i must try it". Very glad I did :)
