In December 2020 there was a logic puzzle advent calender on mathebau.rocks. These puzzles will be uploaded to the puzzle portal in the next weeks.
Rules: Blacken some cells such that in every region there is exactly one orthogonally connected 'stone' blackened. A number indicates how many cells are blackened in the given region.
Black cells of different regions cannot touch orthogonally. If all 'stones' fall down, they do exactly cover the lower four rows of the grid.
Solution code: Size of the 'stones' that are (at least with one cell) in row 5, left to right

Schönes Rätsel, gar nicht so leicht. Nur der Lösungscode...
@Dandelo: Ich habe den Lösungscode geändert, in der Hoffnung, dass er jetzt besser zu ermitteln ist :)
