Short answer

A free Catan Traders & Barbarians 5–6 map generator. The 30-hex stretched 5–6 board, balanced according to standard rules, ready for the T&B 5–6 extension's scaled scenarios: more fishing grounds, more caravans, larger barbarian camps.

What you need to play 5–6 player Traders & Barbarians

The base Catan game.
The Catan 5–6 player expansion.
The Catan Traders & Barbarians expansion (3–4 player base box).
The Catan Traders & Barbarians 5–6 player extension (the dedicated kit for six).

This generator produces the underlying 30-hex layout for that combination. All scenario-specific tiles (fishing grounds, river hexes, oasis, castle, barbarian camps) come from the four boxes above.

What this T&B 5–6 generator builds

30 land hexes: 6 forest, 5 hills, 6 fields, 6 pasture, 5 mountains, 2 desert (matches the 5–6 expansion bag).
28 number tokens placed across non-desert hexes.
Standard balance constraints enforced by default (no 6/8 adjacency, no 2/12 adjacency, no same-number adjacency).
Robber starts on the first desert; the second is dead space (or, in The Caravans, becomes the second oasis).
Shareable seed URL for all six players.

Differences from 3–4 player T&B

Larger board: 30 hexes vs. 19 — more space for caravans to traverse, more coast for fishing grounds, more interior tiles for rivers or barbarian camps.
Build phase: after the active player ends their turn, every other player gets a build phase to spend resources. This carries over from the 5–6 expansion and applies in every T&B 5–6 scenario.
More scenario components: the T&B 5–6 extension provides additional fish tiles, more caravan markers, and extra barbarian-camp tiles to scale each scenario to six players.
Longer games: 6-player T&B title scenario can run 3.5–4 hours. Plan accordingly.

Recommended rules for six-player T&B

Keep all four adjacency toggles at their defaults. Six-player T&B is already long; strict balanced-board rules give the fairest possible starting position. If your group enjoys variance and is playing the gentler scenarios (Fishermen 5–6 or Rivers 5–6), the same-resource adjacency toggle creates thematic clusters without breaking balance much.

T&B 5–6 scenario compatibility matrix

Not every T&B scenario scales cleanly to six players, and even the ones that do have different sweet spots. This matrix summarises what works, what's marginal, and what to avoid in 5–6 player T&B sessions.

Scenario	5–6 quality	Notes
Fishermen of Catan	Excellent	Scales linearly. More coastline = more fishing grounds; pace stays brisk because fish-tile decisions are quick.
Rivers of Catan	Good	Three river hexes on the 30-hex stretched board are less central than on the 19-hex base — bridge density drops, gold-coin pace slows. Game length stretches by 30–45 minutes vs. 3–4 player Rivers.
The Caravans	Marginal	Two desert-oasis tiles instead of one (one per desert on the 5–6 board), but caravan-traffic decisions become a turn-order bottleneck with six. Recommended only if your group enjoys negotiation-heavy Catan.
Barbarian Attack	Excellent	Scales very well. Six knight-building players means barbarian camps fall fast; tension stays high without the game stalling.
Title scenario (T&B)	Avoid	Fixed scenario layout doesn't accommodate the 30-hex board cleanly; six-player title scenario sessions consistently overrun. Use the 3–4 layout for the title scenario instead.

Combining T&B 5–6 with other expansions. The T&B 5–6 extension is technically combinable with the 5–6 Seafarers extension for the Fishermen scenario only — the additional fish-and-sea complexity remains tractable. T&B 5–6 is not designed to combine with Cities & Knights 5–6 in the title scenario; the two systems compete for the same component slots (knights, barbarians) and the rulebook does not provide a unified ruleset. For combined-expansion play, stay at 3–4 players.

Why the generator is most useful for Fishermen, Rivers, and Barbarian Attack. Those three scenarios use the underlying 30-hex board as-is and overlay components on top, so a balanced generator output translates directly into a fair starting position. The title scenario prescribes a fixed layout; the generator's output isn't needed for it.

Common questions

Can I play Traders & Barbarians with 6 players using just the base T&B box?

No — you also need the Catan 5–6 expansion AND the Traders & Barbarians 5–6 extension. They're separate purchases.

How long does a 6-player T&B title-scenario game take?

Plan for 3.5–4 hours. The build phase keeps things moving but the full T&B title scenario plus six-player components is by far the longest standard Catan format.

Which T&B scenarios scale best to six players?

Fishermen 5–6 and Barbarian Attack 5–6 are the most popular six-player scenarios — they parallelise well across more players. The Caravans and Rivers work but move slower. The full title scenario is technically supported but rarely played at six.

Does the build phase change the board layout?

No. The build phase is a turn-order rule; the board is laid out the same way. This generator covers the layout only.
