So Brainy! video review. Classic Game Room presents a CGR Undertow video review of So Brainy! from Viljar Lodi for the iPhone. So Brainy! is a really slick app that combines simple arcade gaming with education. And believe it or not, it's actually a lot of fun. It's like Brain Age, only more of a video game. Or Lumosity, but without the cute girl from the TV ads. You get a flurry of brain teasers and math problems, and you have to answer them correctly and quickly.
