In DragonVale for iPhone and Android, you can redeem various social codes that will give you a gift of different amounts of gems.
Redeeming a code is easy, simply tap the Social button, then tap the Redeem Code button. Type in a valid social code and press OK. If a valid code is entered it will give you a message that it worked, and you should find your gems in the Gifts tab.
Each player in DragonVale has a friend code attached to their account. Entering a code from one of your friends will grant you 25 gems, but you can only enter one friend code per account.
Looking for a friend code to enter? Enter my friend code to receive 25 free gems: 95522815
Using my friend code will give me some gems as well, allowing me to figure out some of the new breeding recipes a bit sooner.
Special Redemption Codes
Every now and then, Backflip Studios releases a social code on their Facebook page that will allow you to get some free gems for a limited time.
The current social code you can redeem for Christmas of 2013 is Presents. Enter this code to receive a gift of 25 free gems. This will expire soon, so use it quick.
