Brain Age: Train Your Brain in Minutes a Day!
Like Nintendogs, Brain Age took the casual consumer market by storm. The premise was attractive to a wide range of players with the notion of making you “smarter” by completing mental exercises for a few minutes each day.
There were several exercises, such as Sudoku puzzles, Stroop tests, math questions, and reading passages, all designed to keep the brain actively thinking. The game would periodically tell you what your “brain age” was based on how well you performed.
The game may not have actually made you smarter; there was a lot of criticism about the methods used. How would counting to 100 as fast as you can make you smarter, anyway? It seemed more likely to make you better at those specific tasks, not smarter as a whole. Still, they were fun exercises to keep you mentally sharp, and overall it was a defining game for the DS era.
