Welcome to the Pet Rescue Community
Do you need help with your game? Ask the Community for help.
You need to connect it to either Facebook or Kingdom, once it connected you just log into which ever one you chose on your new device and your progress will be there. Since it's the first time you'll be connecting there is a small possibility that you'll be set back to level 1 (this happened to someone in my group that was in the same situation) but the good news is if that happens, you'll able to get it restored (she got help from a moderator here after posting about it).
