Bejeweled Blitz is a fast passed puzzle/thinking game that is based around the original Bejeweled. See if you can beat your high score or your friends high school in under 60 seconds. Bejeweled Blitz is a very addicting game that is free in the app store.

I found myself addicted to this game for over 3 hours in one sit down.  Talk about completely zoning in on a game.
