Big Brain Academy (バイブラインアカデミー, Baiburaingu Akademi) is a Nintendo DS game developed by Nintendo and released in Europe in 2006. It is a puzzle game that tests the player's mental acuity. The game is divided into five categories: Think, Memorize, Analyze, Compute, and Identify, each of which contains a series of minigames. The minigames test the player's mental skills in areas such as mathematics, logic, language, and pattern recognition. The objective of the game is to score as many points as possible by completing minigames as quickly and accurately as possible. At the end of each game, the player's performance is evaluated and they are given a 'Brain Weight' score. The player's score is then compared with those of other players in the region and given a ranking. Big Brain Academy has been praised for its unique and challenging gameplay, as well as its ability to improve the player's mental skills.
