What's a good Android game to keep my brain ticking over during those super-long hospital shifts when I need a mental break that isn't, like, *more* medical stuff?

Okay, so I'm usually too tired to learn complicated apps after a 12-hour shift, but 'Trivia Madness' is pretty straightforward. It's got a ton of different categories, so it's not just the same old questions over and over. I like that I can play a quick round or two without having to invest a ton of brainpower – kinda like a mental palate cleanser between charting. Plus, it's actually reliable; hasn't crashed on me once in the last six months, which is saying something. It's a no-fuss approach to trivia, which is exactly what I need when I'm trying to decompress after dealing with… well, you know, everything. I've even used some of the random facts to break the ice with patients sometimes, which is a bonus. It's not gonna win any awards for groundbreaking gameplay, but it works when you need it to.
