What happens after "100 %" Brain Usage"?
I downloaded this for my ipod. I like it, I play it right before bed. I felt that it was a bit too easy to reach 100% and when I did, nothing happened. I continue to do the tests just for fun and my score is always 100% now. It is weird because I feel I don't know if the game is "over". I figured that once one made it to that mark, a "new rank" would be achieved. I don't know. I would like it if the company and/ or game itself said "great job, smartie, go play something else now"... or "hey dummy, we tricked you. this goes up to 1000%". Maybe one is supposed to score all "A plusses" in all the training games/ levels to beat the game...? Aside from that, I like the game. It is even more fun to play not half asleep with one eye closed! I like it just as much as 'Big Brain Academy' on the Wii. I have never played 'Brain Age'.

Good game with annoying traits
The game is better than Brain Age (IMO) due to the large variety of challenges that it presents. However, it has the following highly annoying traits:

- The alarms when the time is about to end: all this does for me is stress me out and makes me miss the last few questions. Running the DS on mute helps for sure.

- The theme music: I haven't found a way to turn this off. It keeps going on and on while one is browsing the menus. Running on mute helps here too.

- The sanctimonious advice: I don't need some animated dumb bell to tell me how to live my life. I (by necessity) practice late at night and the tiresome repetitive advice about my late bedtime really sucks.

- The animation at the start of the game: There seems to be no way to skip the game maker's stupid logo animation every frikking time one starts playing. This wastes about a minute *every* time - highly annoying. I fear that one day I might stab my stylus all the way through my DS due to this stupid trait.

You can see that the above annoyances are really ruining my enjoyment of this otherwise excellent game. I really enjoy the tests and the practice but the annoyances above are just infuriating.

Fun and Very Challenging
This game has different areas in which you can exercise you brain and measure your levels in areas such as logic, focus, memory, math. It's so much fun and some parts are downright tough. Of course, you get better as you go. I love Brain Age 1 and 2 and this as well. So I think if you're a Brain Age fan, you'll have fun with this. Also, I think this was way better than Big Brain Academy. However, my niece and nephew can play that one but not this one. Small children won't be able to do this.

Beats Brain Age 1 and 2 handily
I have both Brain Age games and I have to say that Brain Challenge is a lot more fun and a lot more challening. I like that I can unlock a lot of different games, and that I can play them over and over again should I so choose. I actually enjoy playing these games, which really can't be said for Brain Age. The one thing Brain Age has that Brain Challenge doesn't and that I miss is Suduko, but really, big deal. It's not like Suduko can only be found on Brain Age games.

If you're looking of a something that will keep you engaged and continually be enjoyable, I'd totally go with this game.

Great brain game
I love UBI game designers. This another great example of a fun and entertaining game.
