Don’t worry! If you are already inside the game, go back to the Lobby and tap the Facebook icon on the bottom left of your screen.

The game will open a window asking for you to log in and connect to POP! Slots.

Tap Continue and your POP! Slots status and progress will be restored!

Please keep in mind that only 1 account can be linked to a Facebook or Apple ID at a time. If you had previously connected that account will be logged in and the account you're currently playing will be lost.
