More information about my Double Trouble series as well as links to the other puzzles of the series can be found below the puzzle.
Rules:
Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Killer:
In cages digits must not be repeated and have to add up to the total given in the top left corner of a cage.
Double Trouble: Digits in cells marked with a blue diamond contribute the double value to the cage total.
Have fun solving!
The Double Trouble series:
It's a simple idea. Treat a few cells as if they are double their value. But it has tons of interesting logic and can turn known rule variations completely upside down. With this series I want to show this diversity.
Variant introduction: Easy to moderately difficult puzzles that show the combination of doubling cells with different variants.
Double Trouble - Arrows
Double Trouble - Killer
Double Trouble - Skyscraper
Double Trouble - XV
Puzzles with hidden doubling cells: The doubling cells are not given here, but must be determined by the solver.
Doubles Hidden Inside Squares
I look forward to any feedback and suggestions about the series.
Solution code: Row 9 followed by column 1 (18 digits)

Very nice! The doubling cells add a fun kind of complexity to the killer rules.
