Brain Age 2: More Training in Minutes a Day contains all-new activities to challenge a player's gray matter. The title is a series of training designed to give the brain a workout. The 17 new, engaging activities are all designed to help work the brain. Whether players are playing simple songs on a piano keyboard or monitoring the photo finish of a footrace, they'll love this new mental workout. When starting a new game, players take a series of tests and get a score that shows how old their brain is. This number is called the "DS Brain Age." With daily training over weeks and months, players strive to improve their mental acuity and lower their "DS Brain Age." Progress is charted in graph form. Players can keep up to four save files on one game card. Sharing a game allows players to engage in a picture-drawing quiz or other challenges with family and friends. Players also can use DS Download Play to send a demo to friends or compete with up to 16 players in one of four fun modes.
