Wrecking Ball (Double Trouble)

(Published on 29. September 2021, 13:57 by Mad-Tyas)

Time for a little more advanced logic with doubling cells.

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.
