I'm pretty unsophisticated when it comes to video games, but I do occasionally play escape games when I'm looking for a way to occupy some time. I enjoy them because they require logic and problem solving, but are also just fun.
I saw one recently I thought I'd share: in "Library Labyrinth," you're locked in the library with a serial killer, and you need to find objects and solve puzzles to survive him and get out of the library. Good times, I know, but I also liked that winning this game involved using Twitter (in the game - you don't need an account yourself). Clever, and it also shows (again) how ubiquitous Twitter has become.
