iOS iPhone in app purchase to credits to real life prize?

[danest]

I want to make an app that is free to play but you would be able to purchase "credits" through apples in app purchase. When you use these "credits" and if you successfully complete a task you will then be able to get a prize mailed to you. Is this allowed by apple?

Have you read the iPhone Developer Program License Agreement, in particular section 3.3.20?
