In app purchase + redeem points as gift vouchers
We are developing a multiplayer game in which user has to buy some credit point through in app purchase, then he can multiply those points by winning multiplayer challenges with friends. On reaching a certain level of points, he can reward himself by re-deeming gift vouchers (amazon, ebay, etc) through those points. Does apple allow this type of game structure? Please suggest. -- Thanks, Devarshi ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
