Can I Make A Paper Toss Game?

I want to make a paper toss style game in bb3. And need help with mechanics.

— how do I change the gravity for each scene? Like how the fan changes the x axis gravity

— how do I create a flick movement style?
I want players to slide their ball a certain way to have the x gravity help collision path.

After this is done I will just need to put a collision box on the target.

 

Currently setup as a 3D game, but could change to 2D if needed

 

to answer the question on your title I think something similar was released recently: https://play.google.com/store/apps/details?id=com.kidscorner.swipeshot

 

Thanks! Do you have suggestions for the swipe mechanic? Or the gravity mechanics? See original post for context
