Based on the theories of neuroscientist Dr. Kawashima, Brain Age 2: More Training in Minutes a Day contains all new activities to challenge your gray matter.

• New Activities! The title is a series of minigames designed to give your brain a workout. The 17 new, engaging activities are all designed to help work your brain and increase blood flow to the prefrontal cortex. Whether you're playing simple songs on a piano keyboard or monitoring the photo finish of a footrace, you'll love your new mental workout!
• Keep training! When you start a new game, you will take a series of tests and get a score that shows how old your brain is. This number is called your "Brain Age". With daily training over weeks and months, you can improve your mental acuity and lower your Brain Age. Progress is charted in graph form.
• Expanded multiplayer! you can keep up to four save files on one game card. Share a game allows you to compete in a picture-drawing quiz or an acrostic challenge with family and friends. You can also use DS Download Play to send a demo to friends or compete with up to 16 players in one of four fun modes.
