Play More Brain Training from Dr Kawashima - How Old Is Your Brain (E)(FireX) Online

Remember that weird little DS game where a floating head judged your brain age? This is the sequel, and it’s just as oddly charming. You’ll start by scribbling answers on the touchscreen for simple math problems and memory tests—nothing too intense, but it’s weirdly satisfying when the game tells you your brain’s "age" is younger than you expected.

There’s something about the way Dr. Kawashima’s pixelated face nods approvingly (or sighs in disappointment) that makes you want to retake the tests immediately. The voice recognition for reading aloud is hilariously hit-or-miss, though—half the time it thinks you’re speaking ancient Sumerian instead of counting to 20.

It’s not exactly a hardcore brain workout, but if you like quick puzzles between bus stops or waiting for coffee, this one’s got a weirdly addictive rhythm. Just don’t take the brain age results too seriously.
