What's a good iOS game to play when I'm waiting for the water to boil, something that doesn't need a freakin' PhD to figure out?

Look, most mobile games are a waste of time, right? But Looper! is different. It's dead simple – match colors, make loops, rack up points. No fancy BS, just pure, mindless fun. I can play a round while I'm waiting for the pasta water to boil, or when the sous chef is late with the freakin' shallots. It's not gonna win any awards for deep gameplay, but that's the point! It's a perfect little distraction when you need to clear your head before plating 20 goddamn entrees. Plus, it's kinda satisfying when you get a high score. And the best part? You can play it one-handed while stirring the sauce. Kitchen-tested, chef-approved. Well, at least by me.
