My code's 5536996. To use it you have to get to level 10 and then go into the social menu, tap "Redeem Code", input the code (mine is 5536996 although you may have gotten a different one from a friend) and then tap on "OK" and you'll get 25 free gems.

You can also (at time of posting) input "presents" in the redeem box and get 25 free gems for Christmas.
