To keep your progress and game achievements safe, connect the game to your Google Play (Android) or Game Center (iOS) account! 
 
This will help you to save all your progress even if you are buying a new phone, or using several phones at once.
 
You can continue your game where you left it because Google Play and Game Center automatically saves your progress and allows you to access this data on any of your devices.
 
In addition to that, you can always share your achievements with your friends and watch their progress.
 
To connect your account, follow these steps:
  • Go to the setting section (you can find it by tapping on the button with three stripes at the upper-right bottom of your main screen);
  • Make sure you sign in with your Google Play or Game Center account; 
 
 
The procedure is super fast and it will help you a lot not to lose your account progress!
