What is the difference between a guest account and a Facebook/Apple login account?

Do you want to save your progress and continue the adventure with your peons on another device? Connect your Facebook profile to the game! Once it's linked, you may pick up where you left off with your Peons and continue your exciting adventure.

You get a free present when you link your Facebook profile to the game for the first time too. Not only that, you can play with your friends and trade stickers to complete your sticker sets! Just so you know, when you complete sticker sets, you get more rolls! Awesome, right?!

Using Facebook/Apple login (for iOS devices) will ensure that your game is appropriately backed up and restored if you need it.

If you play the game with a Guest account, you will lose your progress if the game is deleted from your device.

Please note that retrieving your progress is not possible on such accounts.
