android play gift certificat for winning in the game?

So i have been thinking whether this is possible - using corona store library and android play.

One user is ranked highest in a mulitplayer game.
Would it be possible to give him some kind of android play or ingame currency which would allow him to use e.g. 5€ to “buy” ingame items, which the others would have to pay for, sort of a free gift certificate for winning?

If so, can you explain roughly how this would be carried out? would I use some sneaky programming or can android play keep track of this / have this kind of feature?

Thanks in advance, Zwonkie [import]uid: 162464 topic_id: 29529 reply_id: 329529[/import]
