If you've ever tried one of the many popular brain-training games on the Ds, you might understand my frustration. There are quite a few titles out there that claim to "train your brain" in just "minutes a day." Brain Age, Brain Boost, Brain Assist, Brain Challenge-the only requirement seems to be inserting the word "brain" into the title in order to instantly boost intelligence. Amy Nelson at Goozer Nation recently picked up Big Brain Academy from my kids' bottomless stash of Ds games (thanks Gramma)and thought, "Oh, I'll give this a try. Show the kids how it's done."
