It's a good game to play in bursts and the Sudoku alone is worth the $20.
THE BAD: Doesn't allow for long periods of play. The mini-games can become tiresome.
Brain Age: Train Your Brain in Minutes a Day makes full use of the Nintendo DS.
GAMEPLAY is quite good. The game tests your ability to do basic math and memorization. The microphone recognizes words well, and the touch screen is surprisingly accurate. Plus, it does Sudoku well since the use of the stylus works great. However, the game only allows you to do a few things each day which is unfortunate if you want to play the game for more than a few minutes.
GRAPHICS are simple but sharp. The text is legible and the game sports a lot of white. It's easy on the eyes and suits the game. Nothing fancy, but that's okay.
SOUND is okay. There isn't anything great in the game, but it's sort of similar to the music found in Nintendogs. Some voice dialogue could have made the game more lively and the instructions easier to understand.
VALUE is pretty good. For a game that costs $20, it's worth the price. The game can easily be something owners will come back to every now and then. In fact, fans of Sudoku should buy this game just for that reason alone.
OVERALL Brain Age has the potential to last forever. It's a good game to play in bursts (especially since it forces you to do so) and the Sudoku alone pays the $20 admission. However, if you for some reason you hate sudoku (or doing math) there isn't enough content to recommend owning this game.
