You will be unable to restore your progress if you haven't linked your game account to your Facebook account or Apple ID.
If you have linked your account to Facebook or Apple ID:
- Install and launch the game.
- After loading, you'll see two buttons: "Play" and "Save Progress".
- Press "Save Progress" and log in to the Facebook account or Apple ID associated with your game account. If the save data tied to your account is of a higher level than your current game progress, it will overwrite your current save. If your current save data is of a higher level than the previous save, your progress won't be overwritten.
Unfortunately, your lost progress cannot be restored if you haven't linked your game account to your Facebook account. Tech support cannot help with this. However, we can restore any in-game purchases you have made with real money.
