Catan Cities & Knights: Complete Guide
The Catan Cities and Knights expansion is the deepest Catan expansion, adding commodities (paper, cloth, coin), city improvements across three tracks, active knights, and periodic barbarian attacks that punish unprepared players. It transforms Catan from a 60-minute family game into a 2-hour strategy experience. If your group has mastered the base game and wants real depth, Catan Cities and Knights is the expansion.
Fair warning: don’t teach Catan Cities and Knights to first-time Catan players. Learn the base game, play Seafarers if you like, then graduate here.
Commodities: The New Economy
Cities in Catan Cities and Knights don’t just double resource production — they also produce commodities: cities on forest produce paper, cities on pasture produce cloth, cities on fields produce coin. (Hills, mountains, and the desert-adjacent terrains produce double resources as normal, no commodities.) Commodities are spent exclusively on city improvements — they can’t build roads, settlements, or cards. This creates a parallel economy: resources for expansion, commodities for development. Managing both is the core skill of the expansion.
City Improvements: Three Tracks
Each player has three improvement tracks, each with five levels: Trade (yellow) — improves your trading: better bank rates, eventually 2:1. Politics (blue) — stronger knights and eventually the ability to build extra knights. Science (green) — faster development card draws and eventually extra cards. Each level costs commodities (escalating: 1, then 2, then 3…). Reaching level 3 in any track earns you a metropolis — worth 2 bonus victory points and immune to barbarian sacking. The first player to reach level 3 in each track claims its metropolis; it can be stolen if someone later surpasses you. Improvements are where games are won. A level-4 science player draws dev cards at a frightening rate; a level-4 trade player effectively prints resources.
Knights
Knights replace the base game’s soldier cards as the robber-control mechanic in Catan Cities and Knights: knights cost 1 sheep + 1 ore and are placed on intersections like settlements (without the distance rule). A knight must be activated (costs 1 grain) before it can do anything. Active knights can chase the robber off your hexes, block opponents’ building spots, and displace weaker knights. Knights come in three strength levels: basic, strong, mighty. Knight positioning is tactical: place them to guard your best hexes, threaten opponents’ expansion, and contest key intersections. Inactive knights are just expensive decorations — keep them fed with grain.
The Barbarians
This is the expansion’s signature pressure mechanic. A barbarian ship advances along the track each time the event die triggers it. When the barbarians reach the island: total up all active knights from every player. If knights are sufficient, the island is saved and the top contributors get a Defender of Catan card (1 VP). If not, the barbarians sack the island and the player(s) with the fewest active knights lose a city (downgraded to a settlement). This creates a beautiful prisoner’s dilemma. Everyone wants someone else to pay for knights while they build improvements. But if everyone free-rides, everyone loses cities. Watch the barbarian track and make sure you’re never the weakest contributor when it lands.
Catan Cities and Knights Strategy Tips
Balance knights and improvements. All knights and no improvements means you survive but never pull ahead. All improvements and no knights means you lose a city to the first barbarian attack. Science is the strongest track. Extra development cards compound — more cards means more progress, more VPs, more everything. Trade is second (the improved bank rates are quietly enormous). Metropolis timing matters. The first level-3 in each track grabs 2 VP and barbarian immunity — rushing one metropolis early is often correct. Commodities are the bottleneck. You’ll always have more improvement ideas than commodities, so prioritize ruthlessly.
Frequently Asked Questions
Do I need the base game for Catan Cities and Knights? Yes, Catan Cities and Knights requires the base Catan set.
How long does Catan Cities and Knights take? Plan for 2 to 2.5 hours with experienced players, longer while learning. It’s roughly double the base game.
Can I combine Catan Cities and Knights with Seafarers? Yes — the expansions are designed to combine, though the resulting game is long and complex. Learn each separately first.
What happens if I have no active knights when barbarians attack? You’re the weakest contributor (zero), so you lose a city — it’s downgraded to a settlement. Keep at least one active knight whenever the barbarian ship is close.
Is Catan Cities and Knights good for 3 players? It works, but shines at 4. With 3, the barbarian math and knight competition are less tense. For the game’s background, see Catan on Wikipedia.
Catan Cities and Knights rewards groups that want real strategic depth — master its two economies and you’ll never go back to the base game.
