Games like Brain Age on DS?

For the weirdest reason, which I have NO idea why, I'm kinda CRAVING a game like Brain Age. I've looked at Brain Challenge by gameloft, and that's what sounds the most like it. Anyone else have any good ones?
(Haha, I'm kinda afraid to buy Brain Challenge cause it'll go down to a buck the day after I get it... Just like the last 4 games I bought. yeah...)

But honestly I'd stick with Brain Challenge ;-)

i'd go for Biggest Brain. It's awesome because it has Facebook rankings.
