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.
Rules: Put a triangle in some cells, which covers half of the cell (i.e. ◢, ◣, ◤ or ◥). Numbers indicate, how many of the (orthogonally) neighboured cells contain a triangle). All uncolored areas are squares.
Solution code: Row 9 and column 11: Q for ◤, W for ◥, A for ◣, S for ◢ and N for an empty cell.

Ich fand es schon beim ersten Lösen erstaunlich, wie sehr die Quadrat-Bedingung den Rätseltyp verändert.
