Notes
This tutorial is suitable to players on the Olympia server. When you finish binding a Facebook account with an IGG account, it won't take effect unless you enter game or re-enter game (if you are in game when you bind the accounts) 10 minutes later. Once the binding takes effects, you will be able to use the IGG account to win IGGems, GWO Credits, event benefits and more from the IGG official website for the Facebook account.
