I started playing this yesterday with a friend, and it's pretty awesome. It's basically scrabble via mobile to mobile. You make a game, they join then you take turns. So during the day if it's your turn you can plop down a word then check it an hour or so later.

Are there any other games like this? Main feature being you can play it against/with someone like this one, and preferably turn based. Actually if there is a cool more action oriented one I'll check that out too.
