With the breaking bricks game (my top score is 331,200 on that). Give this one a try. My top score on this one is 1,478 at level 26.

Good luck--of course you have to be able to add 2's and 3's really fast with this one, and a couple quick fingers on your left hand would help. I love the back-up music though.
