Some players may not be able to directly log in with GameCenter(@gc), Apple ID(@sa), or Twitter(@wt) accounts on the event page. We strongly recommend you to bind your account (if you are using one) to an email address so that you can join in the event as well (Once the account is binding with your email, you can log in with your email as an account on the event page).

You may follow the next steps to finish the binding:

Firstly, Tap [Account] in the top left corner of the login interface. Press [Bind Another Account] and bind your account with either your Facebook account or email address.

After the binding process is completed, return to the event page and log in with your Facebook account or your email address. If you bound your email address, simply enter your email and password to log in. If you bound your Facebook account, please log in by pressing the exclusive Facebook entrance right under the login button.
