The unique technology contained within Nintendo DS is what makes Brain Training possible.

Nintendo DS has two screens - the lower of which is touch-sensitive. By holding the system sideways, like a book, users can write on the Touch Screen with the stylus as if you were writing with pen and paper. (Left-handed users can turn the Nintendo DS around so that the Touch Screen is on the left side.)

Nintendo DS also features an in-built microphone so you can perform some of the exercises simply by speaking. Plus, Nintendo DS’s wireless communication technology allows for up to 16 people to take part in a Calculation Battle using just one copy of the game. It is also possible to send a demo version of the game to another Nintendo DS.
