Big Brain Academy Unlockables (DS)

How much does your brain weigh? Find out with Big Brain Academy, the DS title that makes mental exercise incredibly fun. Big Brain Academy is a series of minigames (called Activities) that are designed to exercise the brain. Players can "weigh" their brain in Test mode, earn medals for individual activities in Practice mode or play against friends and family in Versus mode.

Big Brain Academy's Test mode will quiz players in five areas: thinking, memorization, computation, analysis and identification. After taking the test, players will be told the "weight" of their brain and areas of strength or weakness - and it will identify a brain type that is similar to their own. Once they have a score, they can keep playing the game to exercise the brain in areas where it needs improvement based on their performance in the Test mode.
