English is not my first language. In college (in the US), a roommate got me hooked on the New York Times crossword puzzle, and I picked up a lot of English vocabulary (along with a ton of trivia) from it.
I'd love to be able to repeat this trick somehow to increase my German vocabulary.
I have found a few crossword puzzle in German online, but they have all been pretty unsatisfying (not necessarily easy for me to solve, just uninteresting and poorly put together).
Does anyone know of a good, regular1 crossword(-like) feature in German?
1 I stress regularity here because I think the reason the crosswords in German that I've found have been uniformly unsatisfying is that they all seemed to be isolated/sporadic efforts. It takes practice to devise and edit crossword puzzles; it's a subtle skill.
