The game is divided into two different rounds, called Ages. During each Age, the King will decree which buildings are to be included in the city. During every Age, players place the Wall Pieces on their board according to the result of the Building Die. They need to include the buildings indicated by the King's Decree and to keep out the dangerous Vikings. The players who manage to close the city earlier, as well as those who include the most Coins, will be rewarded.
