First of all, don't try to create multiple accounts on the same server and on the same device! This is guaranteed to lead to problems.

The following tips will help you keep your progress safe:

1. Make sure to agree to connect the game to Google Play/Game Center/AppGallery when you launch the app for the very first time.
2. Check if your account is connected in the Settings section of the game. If you did everything right, then going to game settings will make you see the sign “Disconnect” on the button "Google Play/Game Center/AppGallery"
3. If your account is still not connected, you should connect it in the Settings menu. Just open the menu, tap the "Connect button" and choose the account you need in Google Play/Game Center/AppGallery.
4. If you haven’t managed to connect the account, contact us and we will do our best to help you.
5. Do not reinstall the game unless necessary! Reinstalling the game too frequently may result in progress loss issues!
6. If a game update doesn’t get installed correctly (too long or endless loading), we recommend you to wait for a while and not to hurry up to delete the game and reinstall it.
7. Cheats, hacks and mods increase your chances to lose your progress for good.
8. Never share your Game Center/Google Play/AppGallery login and password with anyone.
