3DS Puzzle GamesFollow

My mom bought a 3DS and likes the puzzle games. She had a DS and played all the Layton games and the brain age games.

My dad told me for Christmas she wanted Brain Age for the 3DS, but looking around online it looks like it doesn't come out until February. I told him that and he said something about a TV commercial they had seen for the 3DS that had a puzzle game, they thought it was Brain Age.

I'm thinking of just picking up the 3DS Layton game for her, but does anyone know what game they may have seen? I don't recall any 3DS commercials, and I watch a LOT of TV geared towards kids...
