Redeem Code link in rewards

Just wondering how to go about using the “Redeem Code” link in rewards? I am a new player - only about 2 weeks but love this game. I enjoyed Puzzle Quest way back when and this game is even better. I just can’t stop playing and exploring. Great job.

Thanks

Thank you for the fast reply. I will look for it.

Sorry if I mislead you, but that giveaway ended a while ago. I was just using it as an example.

That’s ok. At least I know how they work now. Thanks a lot for the information.
