App Rejected - Gambling

I've just had my quiz app rejected for 'Gambling Violation'. I've been waiting for nearly 5 days for this app to go live when all my others have gone live within a few hours.

The only reason I can think they rejected for these reasons is because I stated in screenshots and the description that the top monthly players would win prizes. The app its self is just a pretty standard quiz app.

Anyone have any similar experience with this? I’ve just submitted an appeal for a review after removing mentions about winning prizes.
