Brain Age for Nintendo DS is a good family game. This game is rated E so every one can play. You go through different activities that keep you thinking and your brain age is determined by how well you do and how quickly you process the information. There are math puzzles, reading challenges, memory tests and observation games that test your brain. You can play sudoku as well. The graffics aren't as sharp as some other games but for the game type and price they are fine. Up to 4 people can have profiles saved in the system but it can be used by anyone using the quick play feature. We occasionally have a few problems with the voice activated activities and our DS can be a bit picky about how we write so we occasionally have answers that are recorded wrong. Overall, I love this game. It's in my car so I can play on trips and during my lunch break at work. It was really exciting when my brain age was more than a decade younger than my actual age. This isn't a game that you play until you beat and then it gets boring, you are constantly trying to do better than before and you can pick different activities everytime you play.
