Logic Masters Deutschland e.V.

This 12th puzzle of my Double Trouble series arose from the idea to combine Double-Trouble with my other current project (Equalines). The overwhelming feedback on my last Equalines puzzle ( We Are All Equal ) was motivation enough to implement this idea now.

At first my intention was to create a medium-difficulty puzzle. But then I noticed that the basic setup of this puzzle was much more restrictive than I had assumed. Suddenly I found myself in the role of the solver who was allowed to discover the logic behind this restriction.
That was extremely satisfying and fascinating and I decided to show just that with this puzzle.
So it has now become a difficult puzzle with several advanced logical steps.

Rules:

Sudoku: Fill every row, column and 3x3 box with the digits 1-9.

Equalines: On each line the digits add up to the same total that has to be determined by the solver. Digits may repeat on a line if allowed by sudoku rules.

Double Trouble: Digits in cells marked with a blue diamond contribute the double value to line sums.

Have fun solving!
