You can play AB Pop! on more than one device and sync the progress between devices by connecting the game to Facebook. Simply connect the game to Facebook on the device on which you have progress to create a backup and play for a bit. Then connect the game to Facebook on your other device to sync the progress to the other device as well.
To avoid the game getting confused by progress levels between devices, we strongly suggest making sure that you close the game app always on one device before switching to play on another device.
