Which parts of the game can I sync via Facebook?

Currently, you can use Facebook only to sync your game progress on buildings you have unlocked and levels you have completed in 20- and 70-level temporary events. 

Please note: game elements like rubies, lives, infinite lives and boosters, boosters, tricks, and puzzles are not synced via Facebook. If you need to transfer such elements to a new device or restore them, please contact our support team.
