Please bind your account to keep it safe in case you have deleted the game or lost your device. Also, you can play with your Base from different devices.

Binding methods vary depending on your devices (Apple or Android).

You can follow these steps to bind your Base:

- Click on your Commander avatar at the top left of the screen.

- Click on settings.

- Click on account.

- Click on bind account, then choose the preferred way to bind your Base, or you can bind your Base with both methods under one condition: Your accounts should not be linked to any other Bases.

Binding methods on Apple devices:

- Facebook.

- Games Center: where you can log in to your Base only from Apple devices because Game Center is only available on Apple devices; in case you have switched your device from Apple to Android and your Base is only linked by Game Center, you will not be able to open your Base in your new device unless you bind it to Facebook also.

Binding methods on Android devices:

- Facebook account.

- Google: Where you can log in to your Base only from Android devices because Google is only available on Android devices, so in case you have switched your device from Android to Apple, and your Base is only bound to Google, you will not be able to open it Base on your new device unless you bind it to Facebook also.

Note: It's important to bind your Base with both available methods to prevent any issue that may affect logging in to your Base in case of a problem with one of the accounts.
