I think that what brings people in to Iphone games is the picture on the app. It may look cool and when you click on it you see that it doesn't look that cool. Or some people might play the game and really like it because the game is easy and they are winning all of the rounds or races. People from all over the world like games because some people like family games and other people like arcade games.  The Iphone has brought gaming to the gaming outside the home.
