How do I restore my game?

If you used the option to bind your previous game to an external account then you will need to play through the initial tutorial until you can access the settings menu. Then go to the Account option and log in again with the details you used to bind it. (IM30 account, facebook etc.)

If you did not bind the game then there is no way for you to access it again. You can contact the game support with your previous account details (name, province etc) and they may be able to retrieve it for you. Go to the same account option in the settings menu and look for the 'retrieve lost account' link.
