Soooo much misinformation. You can have 1 account per iDevice + 1 PC Only account. Linked accounts do not count as a PC only account. To change which Facebook account your account is associated with you need to eMail the developers and request they manually make this change. To link a Mochi account to an iDevice first: Log into Mochi and get your account going 2nd sign into Facebook account that will be associated with the linked account (facebook is a required part of the linking process) if the facebook account is already associated with another game account you cannot use it to link the new account) Third download the game onto the iDevice and go through tutorial making a temporary account which will later be deleted. Fourth go to www.KingdomsAtWar.com and select Link iDevice . Follow the prompts until you get to this screen: Selecte Mochi to link your PC account to the iDevice. Next screen will confirm which account you are keeping and which you will be deleting. All of this is covered under the Transfer & Linking Guide Sticked
