In December 2021 there was a logic puzzle advent calender on mathebau.rocks, containing variants of standard puzzles. These puzzles are now uploaded to the puzzle portal.

In every white (orthogonally) connected area, there is exactly one number, which indicates the size of the area. A question marks stands for any number, but in this puzzle, no number can appear more than once.
