Your in-game progress can be backed up by linking it to a Facebook account, Google account, or Apple ID. After doing so, logging into Facebook, Google, or Apple ID on another device will restore your progress to that device. You can use the same game data on any device on which you can log into the corresponding Facebook, Google account, or Apple ID.

Please refrain from reinstalling the game without first linking it to one of the social accounts above as doing so will cause you to lose your progress.

Please contact customer support in the event that you lose your account.
