Gaming best brain/puzzle games

[Ludvigsson]

Being too lazy to look through all the releases, I was wondering if people can recommend their best brain-traing and/or puzzle games for the DS.

I'm a fan of Polarium over Meteos ...

Polarium is good fun, i'm mega stuck though lol.
I'd say brain training is better than big brain academy.
