Doubletime (Double Trouble - GAS)

(Published on 6. October 2021, 01:35 by Mad-Tyas)

With the 7th puzzle in this series comes an expansion at the lower end of the difficulty scale.
The puzzle is intended as a new, easy introduction to the series for a broad group of solvers. And maybe it will spark a little interest in the other puzzles in the series. It would be a pleasure.

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

Advanced Double Trouble: The puzzles in this section present more complex logic around doubling cells.
Wrecking Ball

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 5 followed by column 5 (18 digits)

I loved this! The break-in was very satisfying and the puzzle was an absolute pleasure for me as a beginner. Perfect balance between being approachable whilst also providing a bit of a challenge. Thank you!

Needed some time for the break-in, but after that, it flowed nicely and easily. Thank you!
