Gameplay
Dr. Kawashima's Brain Training: How Old Is Your Brain? uses educational puzzles that are math, word games, memorization games, and other kinds of games. The point of the game is to keep the player's brain young using these educational puzzles. The player is supposed to try and keep their brain at 20, which the game says is the perfect age. It's based on a book by Ryuta Kawashima. The DS is held like a book on its side with the top screen on the left and the bottom screen on the right (opposite for lefties).

Brain Age Check
The Brain Age Check lets the player check how old he or she is by doing puzzles.

Training
The Training mode lets the player play most of the puzzles without doing a Brain Age Check.

Sudoku
The Sudoku mode was added to the non-Japanese versions of the game since it was so popular.

Reception
Brain Age was a popular game, and sold more than 3 million in Japan, 1 million in the United States, and 2 million in PAL regions.
