If you have access to both devices, then you can link your new device by following the "Link Other Device" instructions in settings menu in the game. Click on the settings menu at the top right corner of the main menu and there you should find the instructions under the account section.
If you have lost access to your old device and account, this is how to regain access to it.
1. Please describe your old account:
- Amount of coins/gems
- Name some of your friends
- Previous usernames
- Clan name
- Previous clans
- Items you own
- Date when your account was created
- Last login date
- Receipts for in-app purchases
2. Connect your new account to Game Center.
When you open the game, you should have a new account. Please finish the tutorial if you haven't already and create a username for this new temporary account.
Then you will need to connect the account to your Game Center. If the game does not automatically sign you in, go to the settings menu, which is located in the top right corner in the main menu. From the settings menu go to account and then you can connect to Game Center by clicking on the icon that says disconnected.
When that is done, please send us your Support Code. In the game's main menu, go to settings and scroll down, press "Support Code". Please reply to this email with the code exactly as it is written.
We will then move the Game Center / Google Play ID back to your original account so that next time you log in, you'll be back on your old account.
