How to redeem gems from in-game offers?

[Unregistered]

I was in the game and news popped up. 6 gems if I downloaded free game- said ok it took me to the app store. I then downloaded the game.

Went back to bakery story and still had the same amount of gems as before.
How do I go about redeeming the gems?

Thank you in advance

Open up the new game and play it for a minute.
