Sugesstions for good Puzzle type games for Nintendo DS?

I am looking to buy a new game for my Nintendo DS.

I love playing games like Tetris, and some of the puzzle games on Mario Party DS.



There are so many games out there, it is hard to know which ones are any good.



Any suggestions on some puzzle type games you've enjoyed??Sugesstions for good Puzzle type games for Nintendo DS?

For me, Platinum Sudoku is awesome. If you're a beginner OR pro, you'll love this game. You even get a trainer to help you every step of the way!
