Rewards and Sweepstakes in App

Sweepstakes is sweepstakes, lotteries is lotteries...

_Quoting the current ASRGs:_
..5.3 Gaming, Gambling, and Lotteries
Gambling, gaming, and lotteries can be tricky to manage and tend to be one of the most regulated offerings on the App Store. Only include this functionality if you’ve fully vetted your legal obligations everywhere you make your app available and are prepared for extra time during the review process. Some things to keep in mind:

-- ..5.3.1 Sweepstakes and contests must be sponsored by the developer of the app.
-- ..5.3.2 Official rules for sweepstakes, contests, and raffles must be presented in the app and make clear that Apple is not a sponsor or involved in the activity in any manner.

• - ..5.3.3 Apps may not use in-app purchase to purchase credit or currency for use in conjunction with real money gaming of any kind, and may not enable people to purchase lottery or raffle tickets or initiate fund transfers in the app.

• - ..5.3.4 Apps that offer real money gaming (e.g. sports betting, poker, casino games, horse racing) or lotteries must have necessary licensing and permissions in the locations where the App is used, must be geo-restricted to those locations, and must be free on the App Store. Illegal gambling aids, including card counters, are not permitted on the App Store. Lottery apps must have consideration, chance, and a prize.

Will Apple allow me to do this or will my app get rejected? 

App Review isn't here, there are no pre-reviews, no one here can promise what App Review will/won't allow/reject.

You'll only be afforded the opinions of unpaid referrees here, and mine is that based on the brief app exposition provided, with no details on if the app is paid, free, IAP, or how rewards are earned and then redeemed/converted to sweepstakes entries, odds of winning, etc. etc. you may have to build it, submit it and run the review gauntlet, fingers crossed.

Good luck.

So 2 years later, do we have any answers on what happened?

I was thinking of doing something similar in my app as part of a promotional thing, users would be able to play a "game" that would have similar odds to winning the lottery for a big payday. However, no one pays anything for the app or to participate in the game.

Let’s continue this question a little further. I have a client that would like me to build a ticket app to replace using the paper raffle ticket For his events. At the end of the event he does a drawing for giveaway. This is not done in app and not monetary but could be a gift basket. Is this allowed if the number wining person is randomly selected by a script in the back end and the users is notified by email? Can the winner be notified in app?
