Normal sudoku rules apply (ie Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box). Zombie Cages: Digits in cages must sum to the number in the initial top-left corner, and digits cannot repeat within a cage. ALL cages must grow by at least one orthogonally connected cell (and could grow by more than one!). Different cages cannot share cells.
