Rules:

NEARLY normal sudoku rules apply. Place the digits 0-8 once each in every row, column, and 3x3 box.

Exactly one cell in each row, column, and box is a Doubler. Doubler cells contain a complete set of the digits 0-8. The value of a Doubler cell is equal to its digit multiplied by 2. (All other cells have a value equal to their digit.)

Arrows: Values along an arrow sum to the value in the attached circle.
