Rules:
Normal sudoku rules apply.
In a cage (marked with dotted lines) digits may not repeat and must sum to the total at the top left of the cage. If no total is given, the sum of that cage is equivalent to all other cages with no given sum.
The shaded cell must be at least 6.

Added shaded cell to fix multiple solutions. And adjusted rules to make sure they explain the rules for killer properly.

Usually in killer sudoku, digits may not repeat within cages. Is that supposed to be a part of the rules in this puzzle?
