Brain Age: Train Your Brain in Minutes a Day!

Brain Age: Train Your Brain in Minutes a Day!, known as Dr Kawashima's Brain Training: How Old Is Your Brain? in the PAL regions, is a 2005 edutainment puzzle video game by Nintendo for the Nintendo DS. It is inspired by the work of Japanese neuroscientist Ryuta Kawashima, who appears as a caricature of himself guiding the player. Brain Age features a variety of puzzles, including Stroop tests, mathematical questions, and Sudoku puzzles, all designed to help keep certain parts of the brain active. It was released as part of the Touch! Generations series of video games, a series which features some games for a more casual gaming audience.
