Zynga was once insanely successful as well, making north of $2.3 million per day with a 47% profit margin: http://online.wsj.com/article/SB1000142405274870351550457614...

And then their profits dropped 95% year-over-year... But that's the nature of mobile gamers and mobile games. The players are extremely fickle, and the games lack the depth and complexity necessary to keep people engaged over long periods of time. People flock from one fad to the next.

So far, I don't think we've seen anything but a bunch of one hit wonders in the mobile gaming industry. Draw Something, Words with Friends, Fruit Ninja, etc. Maybe Supercell will be different, but it doesn't seem likely.
