Ad on live quiz

I’m creating live trivia game (almost finished).
The live game show will be held in specific time.
User can watch one ads to gain life if they want.only one ad is allowed per 24.
Can I use ad for that purpose?
AdMob/Facebook will approve for that kind of app ?
And Kodular will give me assess to use ads ?

Yes, you are ready to go. I don’t think so you will have any issue. Neither with admob/Facebook nor Kodular.

Use rewarded video ads for that. If you use banner / Interstitial ad in this point, it would be considered as forcing to user.

If i start showing ad from starting(I mean without having lots of user),will be there any problems from ad network?
And also have wallet feature,is it okey ?
