Rules:

Normal Sudoku rules apply.

Digits in a cage may not repeat, and sum to the clue in the top left corner.

Nine cells (one in each row/column/box) are doublers, and count as double their value in cage sums. Each digit appears in exactly one doubler. Doublers are not necessarily in cages and doublers cannot repeat within a cage.
