Those who have trained their brain to a healthy age can now test its "weight" in Big Brain Academy, the second title in Nintendo’s medley of mental minigames. The title includes a series of brainstimulating exercises designed to improve thinking, memorization, computation, analysis, and identification. After taking an initial test to identify cognitive strengths and weaknesses, players will receive a brain weight score that will hopefully increase over time with daily practice in each of the five categories.
