The base game of CATAN is a modern classic, but if you’ve played it a few times, you might be wondering how to keep the experience fresh. That’s where expansions come in. CATAN offers a range of expansions that add new mechanics, scenarios, and ways to play—each appealing to different kinds of players. Whether you’re looking for deeper strategy, more players, or exciting twists, here’s a breakdown of the best CATAN expansions and what makes each one worth playing.
The Best CATAN Expansions
1. CATAN: Seafarers
What it adds:
Ships, exploration, and island hopping.
Why it’s great:
Seafarers expands the board with sea routes, new islands, and more variability. Instead of building roads, you’ll build ships across water, discovering islands that offer new resources and bonus points. It keeps the core gameplay intact while adding just enough variety to feel fresh.
Best for:
Players who want more exploration and variety in map layouts.
2. CATAN: Cities & Knights
What it adds:
City development, commodities, barbarians, and defensive knights.
Why it’s great:
This is the most strategic expansion. Cities & Knights replaces development cards with a new system of commodities and city upgrades. You’ll also have to work with (and against) other players to fend off barbarian attacks. It adds depth without being overwhelming once you’re familiar with base CATAN.
Best for:
Experienced players who want more challenge and strategic decisions.
3. CATAN: Traders & Barbarians
What it adds:
Five mini-scenarios, new rules for 2-player games, and a modular way to mix and match features.
Why it’s great:
CATAN: Traders & Barbarians is a highly customizable expansion. It includes multiple smaller variants like fishing, camel caravans, and barbarian attacks, which you can combine as you like. It also has excellent 2-player rules, which the base game lacks.
Best for:
Players who like modular variety and want to keep changing how they play.
4. CATAN: Explorers & Pirates
What it adds:
Mission-based scenarios, exploration, pirates, and new mechanics for ships and crews.
Why it’s great:
While Explorers & Pirates is the most different from classic CATAN, it offers a grander sense of adventure. You’ll discover new lands, transport settlers, and even battle pirates. Each scenario builds on the last, adding complexity and story.
Best for:
Players who enjoy thematic games and progressive scenario-based play.
5. CATAN: 5-6 Player Extensions
What it adds:
Extra components to let more people play.
Why it’s great:
Every main expansion has its own 5-6 player version. These don’t add new rules but do let more people join the fun. Just note that games take longer with more players.
Best for:
Larger groups and game nights.
Final Thoughts
If you’re just starting with expansions, Seafarers is the most accessible and adds a lot of replay value. For a deeper, more competitive experience, go with Cities & Knights. Want to mix things up every time you play? Traders & Barbarians is your toolkit. Each expansion brings something different, so the “best” one depends on how you like to play CATAN.
Pro tip: Don’t forget that most expansions require the original base game to play.
