You enter the e-mail address of a friend (or select a friend from your friend list) and select a map. A challenge will then be sent to your friend by e-mail. If he accepts, a game will be created and you each take turns to play. At the end of each turn a mail will be sent out to the other player to notify him of the move. You'll have 5 days per turn, so you can for example spend 10 minutes per day to make your move.
