Brain Age: Train Your Brain In Minutes A Day NDS comments

Give your gray matter the workout that it needs to stay sharp and focused.
Brain Age: Train Your Brain in Minutes a Day is inspired by the research of Dr.
Ryuta Kawashima, a prominent Japanese neuroscientist. His theories revolve
around keeping brains stimulated by performing mental activities quickly.

• Brain Age is a series of exercises designed to give brains a workout.
  Activities include performing math problems, counting people going in and out
  of a house, drawing pictures on the touch screen and reading classic
  literature out loud.


• When users start a new game, they will take a series of tests that
  determine their brain age within the game. This number is called the “DS brain
  age.” As the player uses the software over a series weeks and months, their
  ability to perform the exercises will improve and their DS brain age will
  decrease. Progress is charted in graph form.


• Users can keep up to four save files on one game card. Sharing a game
  allows them to compare their results with those of family and friends. Users
  also can send a demo version of Brain Age to friends or compete with up to 16
  players in a battle to see who can solve math problems the fastest.


• Brain Age also includes more than 100 sudoku puzzles, which are among the
  most popular types of brain-challenging puzzles in the world.
