Shuffle terrain tiles and number tokens for a unique Settlers of Catan setup every time. Supports the base game (3–4 players) and the 5–6 player expansion. Balanced mode keeps 6 and 8 off adjacent hexes.

Number Tokens
Red tokens (6 & 8) have the highest probability — 5 ways to roll on 2d6.
Catan (originally Settlers of Catan) is a multiplayer strategy board game designed by Klaus Teuber and published in 1995. Players build settlements, cities, and roads on a modular hex-tile board, collecting resources based on dice rolls and their settlement positions. Because every hex is a different terrain type producing a different resource, and because each hex is assigned a number token that determines how often it produces, the placement of tiles and tokens fundamentally shapes the entire game. A well-randomized board prevents any single resource or number from dominating, creating a balanced competitive environment from the very first turn.
The standard 3–4 player base game uses 19 terrain hexes arranged in a 3-4-5-4-3 row pattern, surrounded by ocean frame pieces. Eighteen number tokens (2 through 12, excluding 7) are distributed across the resource hexes, with the desert hex receiving no token. Tokens marked with a red dot (6 and 8) are the most valuable because there are five ways to roll each number on two dice. Placing settlements at intersections adjacent to multiple high-probability hexes — especially if those hexes produce different resources — is the core strategic goal of setup. Our balanced mode enforces a GS1-style constraint: no two red-dot hexes (6 and 8) may share an edge, preventing any single settlement from having two hyper-productive neighbors.
| Terrain | Resource | Hex Count (Base Game) | Strategy Value |
|---|---|---|---|
| Forest | Lumber | 4 | High early-game (roads & settlements) |
| Pasture | Wool | 4 | High early-game (settlements) |
| Fields | Grain | 4 | High mid-game (cities & dev cards) |
| Hills | Brick | 3 | High early-game (roads & settlements) |
| Mountains | Ore | 3 | High late-game (cities & dev cards) |
| Desert | None | 1 | Negative (Robber starts here) |
What is the recommended Catan board setup for beginners?
The official Catan rulebook includes a "beginner's setup" — a fixed, non-random board with pre-assigned hex and token positions designed to teach the game's resource flow without overwhelming new players. After one or two games, the rulebook encourages switching to the fully randomized setup. Our generator's "Balanced" mode is a good middle ground: it randomizes the board but enforces the constraint that no two high-probability (6 and 8) hexes share an edge, giving a fair board without the flat predictability of the fixed layout.
Why randomize the Catan board?
Randomizing the board prevents experienced players from memorizing optimal first-settlement positions and exploiting them game after game. A fresh random layout each session means every player must evaluate the new board from scratch, rewarding strategic thinking over rote familiarity. It also dramatically increases replay value — the number of possible board configurations is astronomically large, effectively guaranteeing no two games play the same way.
What are the number token probabilities in Catan?
In Catan, resources are produced when the combined total of two six-sided dice matches a hex's number token. The probabilities on 2d6 are: 7 (6/36, but no token), 6 and 8 (5/36 each — marked red), 5 and 9 (4/36 each), 4 and 10 (3/36 each), 3 and 11 (2/36 each), 2 and 12 (1/36 each). "Pip count" is a shorthand — each dot under a number represents one way to roll it. A settlement touching a 6, 8, and 9 has 5+5+4 = 14 pips, the theoretical maximum for any three-hex intersection.
How does the Robber affect strategy?
The Robber is placed on the desert at game start and does nothing. When a 7 is rolled (the most common result at 6/36), the active player must move the Robber to any resource hex, blocking that hex from producing until the Robber moves again. The player also steals a random resource card from any opponent with a settlement adjacent to the new Robber position. Strategically, players use the Robber to target the leader's best hex, punish opponents with few alternate resource sources, and protect their own critical hexes by keeping an eye on Knight Development Cards to chase the Robber away.
What is the difference between base Catan and Catan expansions?
The base Catan game supports 3–4 players on a 19-hex board. The Seafarers expansion adds ocean hexes, ships, and island discovery, supporting 3–4 players on larger, multi-island maps. Cities & Knights introduces commodity cards, city improvements, and barbarian invasions, significantly increasing complexity. The 5–6 Player Extension adds extra hexes, tokens, and frame pieces to support two additional players on either the base or Seafarers map. Explorers & Pirates is a later expansion with missions and pirate ships. Our board generator covers the standard 3–4 player and 5–6 player base game configurations.
