All of the top grossing free-to-play games are like that. DragonVale used to occupy the top spot, and is similar.
The current #7 top-grossing app is Slotomania. I like to think of all these free-to-play games like Slotomania. They're addictive, have colorful graphics, and either make you wait to earn more coins, or succumb to your addiction and pay up (real $) to get (fake $) coins NOW.
