If you've been drawn to receive a reward, they will contact you (they will try twice before drawing a new winner) to talk about the details, confirm your identity, make you sign some forms. But likely that's only for the physical rewards.
For the in-game rewards, I'm sure they will still contact you via the email you entered a contact email. Either they will send you a code in the email, or more likely just add the items to your acount.

And for in-game rewards do we ha e to kill someone or is it also a random pick for just paying the game?
