We are looking to do a small game on iPhone and Android that ends in a coupon for the winner. It will start with the user playing the game of filling a balloon with water using a water gun. If the balloon is filled within a set time, then, the balloon blasts and a coupon with bar code pops out. If not, the user can play again only the next day. The app will be integrated with Facebook for login, posting the success, posting the coupon etc.
Pls see attached screens.
