User Profile

Hello, my app keeps being rejected because "the primary purpose of your app is to encourage users to watch ads or perform marketing-oriented tasks, which is not appropriate for the App Store." To make simple, my app concept is like a tombola, if user wants to validate a game, he has to watch a rewarded ad. After the first rejection, I changed my concept and now, to validate a game it cost 50 appcoins, and to get appcoins, user need to choose between 15 cards, each permits to earn appcoins, and for some of them (with ad badge, to alert users...), you have to watch ad (those cards have the highest value). I don't understand why it's being rejected, it's the goal of rewarded ad to make users watch an ad to get items. Do you have advices please, to be in compliance with apple guidelines, thanks
