Help me choose my wife’s next DS game

My wife doesn’t play many games ’ maybe 2-3 per year, if that. When she does, she prefers the DS. Here are some of the games she’s most enjoyed in recent years:

  • Picross 3D
  • Bejeweled
  • Tetris/Dr. Mario
  • Sudoku
  • Phoenix Wright (although her interest in that waned)

As you can see, she likes puzzle games. But she doesn’t like Professor Layton. I suspect she doesn’t care for story-driven games. She just likes to jump in and immediately start solving puzzles.

That said, what games would you recommend she play?
