(stylized as Brain Age2), also known as More Brain Training from Dr. Kawashima: How Old Is Your Brain? in PAL regions, is an edutainment video game and the sequel to Brain Age: Train Your Brain in Minutes a Day! (2005). It was published and developed by Nintendo for the Nintendo DS handheld game console. Before the game begins, the player must perform a Brain Age Check to determine their brain age, which ranges from 20 to 80, to determine approximately their brain''s responsiveness. A brain age of 20, the lowest age that the player can achieve, indicates that the player''s brain is as responsive as that of an average 20-year-old. After the player is told their initial brain age, they can complete a series of minigames to help improve their brain''s responsiveness, after which they can run Brain Age Check again to determine their updated brain age. Critics were generally favorable towards Brain Age 2, which received aggregated scores of 77% from Metacritic and 79.04% from GameRankings. Praise focused on improvements made on Brain Age, while criticism targeted the game''s inability to consistently understand written and spoken answers.
