In order to play on two (or more) devices, you need to play your game on your devices in turn (non-simultaneously) and make progress. (Don't lock your device with the game running or don't leave your device with the game running as the device will lock and the progress you’ve just made may fail to be saved.) Exit the game correctly: Close it to your multitasking bar and then swipe it away from the multitasking bar.
Make sure you go to the city view before you exit the game (it won’t sync correctly if you close the game on match-3 levels, in Friends menu, ect.).Otherwise it may cause serious issues with saving and transferring your progress across devices. Don't play the game if it's open on your other devices. Don't play the game on two or more devices simultaneously.Both devices must meet the minimum system requirements.You must have the latest game version on both devices.NOTE: The downloaded game progress will completely replace your current progress. A window telling you to download the saved game from our cloud will pop up.Log in Facebook using the same account you used on the first device.Make sure you have a stable internet connection.
