Facebook account connection works on all devices, so it's the best choice for you if you want to play the game on both iOS and Android devices.
 
Connecting is super easy to do - just go to account connection in the title screen or in-game settings, select the Facebook option and you will be ready to go. We will never post to your wall or send any information to your friends.
 
Note: If you remove your account from Facebook, you could lose your account and we will not be able to recover it.
