It's time for a Killer Sudoku... with a twist!

Rules:

Normal sudoku rules apply. Every row, column and box must contain the digits from 1-9.

Normal killer sudoku rules apply. Within each cage, digits cannot repeat and must sum to the given total in the top-left corner.

A single digit from 1-9 is worth twice its normal value throughout the entire grid, and is therefore counted twice if it appears in a killer cage. This digit is to be determined by the solver.

Here is an 6x6 example to demonstrate the last rule. Notice that the digit 5 is counted as a 10 in all killer cages. Try the example puzzle in SudokuPad.
