Zur Klarstellung: Die rote Summe muss so klein wie möglich sein. Unter allen Lösungen mit dieser minimalen roten Summe ist dann die gesucht, bei der die blaue Summe am größten ist.

@steelwool: It seems like there was a written mistake in the update, which could caused the un-labeling.
I'm sorry for the inconvenience :)

Since this is a Sudoku puzzle, could you please add the sudoku tag?
-- Hi, the setup seems to have changed. It asked me if I was entering a sudoku and I said yes. There is no symbol for sudoku to select any longer, so I am surprised it didn't get added after the question. Added as a bespoke tag
