CATAN official Game Rules & Almanac
Opening plans and decisions
CATAN combines random production, public positions, and free trading. You cannot control the next gain entirely, but sites, exchanges, and plans alter dependence on luck.
Free trade, roads/sites, and robber production make observing others' plans part of your turn.
Start here if you are new
Read numbers and resource uses together
Free setup or several legal settlements at a road end.
Check production covering costs, then number probabilities and expansion room.
Abundant mismatched resources still need trading.6/8 are common, but resource combinations determine next moves.
More resource diversity may forgo higher yields/ports.
With reliable trade/special port, compare concentrated production, but check legal paths to the port first.
Compare new-settlement opportunities before upgrading
Both settlement/city affordable, legal empty intersection, and pieces available.
Compare new terrain, numbers, ports with doubled old production.
Both normally net 1 point, but future resources/space differ.
New settlement may need roads; city costs more ore/grain without new terrain coverage.
If expansion risks blockage, check new site first; productive existing sites may support repeated cities.
Calculate opponents' next moves before trading
An opponent nears 10, especially asking the last needed resource on their turn.
Combine traded resources with their possible city/settlement/award.
Active player 10 ends immediately; your improved hand must pay off in time.
Refusal leaves your gaps and may not stop bank/other trades.
Offer a trade not completing their winning cost, or pursue your own earlier victory.
Comparing two choices
New settlement or upgrade old one?
You have 1 each brick/lumber/wool,2 grain,3 ore.Own road reaches legal B beside new lumber/brick/wool.A settlement neighbors grain/ore.All pieces available.
Build settlement at B
Net+1 and expand lumber/brick/wool production.
Pay 1 each brick/lumber/wool/grain;3 ore/1 grain remain, not enough for city yet.
Upgrade A to a city
Net gain: 1 point. Production from A's adjacent grain and ore doubles.
Pay 3 ore and 2 grain; B stays empty, risking your expansion opportunity.
Both moves add one point. Compare new coverage, existing number production, and whether B may be blocked before investing.
Trade for lumber or keep the grain your opponent needs?
Opponent's turn: they have 9 points, 3 ore, 1 grain, and a settlement to upgrade. They offer 1 lumber for your 1 grain. You need lumber but can build only on your turn.
Accept trade
You get the lumber you need.
Opponent reaches 3 ore + 2 grain, upgrades for a net 1 point, and can win immediately.
Decline this offer
Keep grain to avoid directly completing the opponent's winning payment.
You still lack lumber; the opponent may find resources elsewhere.
Your own building opportunity comes too late after this trade. Check other immediate winning routes before negotiating a counteroffer.
Details that are easy to miss
- A city replaces a settlement for 2 total points, not 3.
- On 7, count only resource cards. Playing a Knight does not make everyone discard half.
- New Knights/progress cards cannot be played this turn. Announce 10 points only on your own turn.
Production depends partly on dice luck; it shines with three or four players willing to negotiate.
A decision example
You need one material for a city; trading supplies it but lets another finish an important road. Judge future effects, not equal card counts alone.
Why teach more than building costs?
Costs explain how, while trading/expansion explain why. Show roads, settlements, production, and exchange as a connected system.
Different needs make trade possible
Different layouts produce mismatched needs. Trade converts spare materials into buildings but helps opponents too; prices convey board information.
If everyone always lacked the same resource, trading would shrink and building depend more on personal production.
