Tired of the same old island layout? Our Catan Board Generator shuffles a brand-new Catan map every time you click. It randomly arranges all 19 terrain hexes, deals out the 18 number tokens fairly — with the powerful red 6s and 8s never touching — and scatters all 9 ports around the coast. Whether you search for it as a generator catan tool or a catan board generator, this is the fastest way to a fresh, balanced island for your next game night: no shuffling tiles by hand, no arguments about setup, just a fair random board in one click.
How to Use the Catan Board Generator
- Look at the board that is already generated for you on this page — a fresh random layout appears automatically.
- Study the island: each hex shows its resource (Wood, Sheep, Wheat, Brick, Ore, or Desert) and its number token, with probability dots under the number.
- Check the ports around the edge — you will find four generic 3:1 ports and five 2:1 resource ports, randomly placed.
- Not in love with this island? Click Generate New Board for another completely random layout.
- Recreate the layout with your physical game tiles, place the robber on the desert, and play.
What Is a Catan Board Generator?
A Catan board generator is a free online tool that creates randomized Settlers of Catan board layouts. It shuffles the terrain hexes, places the number tokens, and positions the ports for you, so you can copy the island onto your physical game instead of laying tiles out manually. Because the official composition is always preserved — the same 19 hexes, 18 tokens, and 9 ports — every generated board is a legal Catan island, just never the same one twice.
How the Standard Catan Setup Works
The official setup has two flavors. The rulebook offers a fixed beginner layout printed in the manual, designed so new players get even access to every resource. The variable setup shuffles the terrain hexes face down, builds the island randomly, then places number tokens in a spiral order around the board. Ports are shuffled and placed around the coast, and the robber starts on the desert. Our generator follows the variable-setup spirit, with one widely trusted addition: the balance rules below.
What Makes a Catan Board Balanced?
A balanced board spreads luck evenly. High numbers (6 and 8) are not stacked on touching hexes, resources are not clumped in one corner, and every starting position has a fair shot at wood, brick, wheat, sheep, and ore over the course of the game. Think of it as a balance score: compare how many pips (dice probability) each resource holds against an even split. A board near 100 percent pays every resource almost equally; a board at 60 leans hard on one or two resources, and someone at the table will feel short-changed all night. Fair generators chase the high scores; pure-random generators accept anything.
The Four Fairness Rules
1. Keep 6 and 8 apart. The printed manual states this one outright. Sixes and eights each pay on 5 of the 36 dice combinations — the most of any number. A pair of them on one corner decides the game early, so red numbers never touch on a fair board.
2. Keep 2 and 12 apart. The mirror of the first rule. Twos and twelves each pay on just 1 of 36 combinations; stacking the two weakest numbers in one corner wastes that whole region.
3. Keep matching numbers apart. If two hexes with the same number share an intersection, one dice roll pays double at that corner and nothing elsewhere. Spreading duplicates evens the table out.
4. Keep matching resources apart. Big blocks of one resource make that corner monopolize production and everyone else starve for it. Breaking up resource clusters is the usual fix for the most common complaint about fully random boards.
Our generator enforces the first rule always (separated 6s and 8s) and shuffles everything else freely, which most groups find strikes the right balance between fairness and chaos. Tournament-style boards apply all four.
Terrain Hexes and the Resources They Produce
The 19 terrain hexes follow the official mix: 4 Fields (produce Grain/Wheat), 4 Pasture (produce Wool/Sheep), 4 Forest (produce Lumber/Wood), 3 Hills (produce Brick), 3 Mountains (produce Ore), and 1 Desert (produces nothing — the robber starts there). Every settlement or city touching a hex collects its resource when that hex’s number is rolled, so the terrain mix shapes the whole economy of the island.
Number Tokens and Dice Probability: The Pip Table
Two dice give 36 possible combinations. The dots under each number token — its pips — count how many of those 36 combinations produce that total. That is why a 6 or an 8 pays five times more often than a 2 or a 12.
| Number | Pips | Chance per roll |
|---|---|---|
| 2 | 1 | 2.8% |
| 3 | 2 | 5.6% |
| 4 | 3 | 8.3% |
| 5 | 4 | 11.1% |
| 6 | 5 | 13.9% |
| 8 | 5 | 13.9% |
| 9 | 4 | 11.1% |
| 10 | 3 | 8.3% |
| 11 | 2 | 5.6% |
| 12 | 1 | 2.8% |
(Seven has no token because a roll of 7 moves the robber instead of paying out.) In a typical game the dice roll about 100 times, so a 5-pip hex can be expected to pay roughly 14 times, while a 1-pip hex pays about 3 — plan your starting settlements accordingly.
Ports Explained: Harbors and Trade
Nine ports ring the coast: four generic 3:1 ports (trade any 3 identical resources for 1 of your choice) and five 2:1 resource ports (trade 2 of the named resource for 1). Random port placement keeps trading strategy fresh — a wood-heavy island plays completely differently when the 2:1 wood port lands on the far coast.
Beginner Layout vs Fully Random Boards
The beginner layout guarantees even spacing and gentle numbers, which is kind to new players. Fully random boards create natural scarcity — one resource rare and expensive, another flooding the table — which experienced players find more interesting. Our generator sits in between: randomized terrain and ports, with the 6-and-8 rule protecting the board from the one layout flaw that can quietly decide a game before it starts.
Example Board Breakdown
Imagine this island: a wheat 6 and ore 8 hold the center, brick 5 and wood 9 guard the east coast near the 2:1 wood port, sheep spreads across the north, and the desert sits harmlessly on the southern edge. The strongest starting intersections touch the 6, 8, and 5 — three different resources, three different numbers — exactly the kind of spread a fair generator aims for.
Strategy Tips for Random Boards
Prioritize number diversity over raw pips: settlements on 5, 6, and 9 beat three hexes all numbered 6, because production arrives more steadily. Secure at least one port strategy — if your best numbers are wood and brick, the 2:1 wood port is gold. Watch for the scarce resource early; on random boards, whoever monopolizes the rarest resource controls mid-game trading. And when the desert lands near your planned expansion spot, reroute — do not build toward a hex that never pays.

Frequently Asked Questions
What is a Catan board generator?
A Catan board generator is a free online tool that creates randomized Settlers of Catan board layouts. It shuffles all 19 terrain hexes, places the 18 number tokens fairly with no adjacent 6s and 8s, and randomly positions the 9 ports — giving you a fresh, balanced island for every game.
How many hexes and tokens does the generator use?
The generator uses the official composition: 19 terrain hexes (4 Wood, 4 Sheep, 4 Wheat, 3 Brick, 3 Ore, 1 Desert), 18 number tokens from 2 to 12, and 9 ports (four 3:1 and five 2:1 resource ports). The desert receives no token and is where the robber starts.
Why are the 6 and 8 never next to each other?
Sixes and eights (the red numbers) are the most frequently rolled totals after seven. If a 6 and an 8 touched, one intersection could produce on more than a quarter of all dice rolls, creating an overpowered starting spot. Official Catan setup rules — and our generator — always keep red numbers separated.
What do the dots under each number mean?
The dots show how likely that number is to be rolled with two dice. Five dots (6 and 8) means most likely, about 13.9% of rolls each. One dot (2 and 12) means least likely, about 2.8%. More dots means the hex produces more often.
Is a random board fairer than the beginner layout?
Both are fair in composition — the same hexes, tokens, and ports are always used. The beginner layout guarantees even spacing, while random boards create natural scarcity and variety, which most experienced players find more interesting. Our generator guarantees the one balance rule that matters: separated red numbers.
Can I use this for the physical board game?
Yes. Generate a layout on screen, then arrange your physical Catan tiles, number tokens, and port pieces to match it. Place the robber on the desert hex, and you are ready to play a completely fresh island.
What are the official Catan setup rules?
The rulebook offers a fixed beginner layout and a variable setup: shuffle the terrain hexes, build the island, then place number tokens in spiral order, put ports around the coast, and start the robber on the desert. Keeping 6 and 8 apart is part of the printed manual’s guidance, while stricter rules — separating matching numbers or resources — are popular house rules that fair generators apply for you.
How many possible Catan board combinations are there?
Far more than anyone could play in a lifetime. Just arranging 19 hexes and 18 tokens produces an astronomical number of distinct islands, which is exactly why a quick generator beats sorting tiles by hand before every game night.
