Catan: Cities & Knights (6th Edition)

Knights are not used in the form of cards; instead, they are represented by wooden tokens that are placed on unoccupied intersections.Each token has an “active” side depicting a knight helmet in color and an “inactive” side depicting a black-and-white knight helmet. A knight can only fight after he is activated; activation costs one grain. After paying the grain, you turn the knight token over so that its active side is face up. Each ring on the token counts as one strength point.
If the knights of all players combined have enough strength points to defeat the barbarian army, the danger is averted for the moment. However, if the Catanian knights are too weak, a city will be raided and downgraded to a settlement.
This unfortunate event always affects the player who had the lowest total strength of active knights when the barbarians attacked. Besides defending Catan, knights can also be used to chase away the robber or to displace another player’s knight.
When you are not busy defending Catan, you are competing for the metropolises, which represent two additional victory points. In order to establish a metropolis (which is placed on top of a city), you first need to improve your cities.
The construction of city buildings, such as the Library, Market, Abbey, or Trading House is indicated on the Progress Track.
 
You pay for city improvements with commodities such as coins, cloth, or books. How do you get commodities? Instead of two resources, cities adjacent to mountains, pasture, and forest hexes produce only one resource but also one commodity derived from the respective type of resource.
With increasing city improvements, the odds to obtain new progress cards become more favorable. Cards such as “Mining,” “Irrigation,” or “Building Crane” allow for faster settlement activities. Cards such as “Merchant,” “Merchant Fleet,” “Trade Monopoly,” or “Resource Monopoly” create advantages with regards to trade. On the other hand, you can bother stronger players with cards such as the “Intrigue,” “Espionage,” or “Diplomacy.”
Get used to a tougher life on Catan – and a longer but also more exciting game. The first player to reach 13 victory points is the winner.
