What is a Catan board generator?
A Catan board generator lays out terrain and number tokens so you do not have to shuffle everything by hand. Whether you want the official beginner island, a completely random map, or a calmer fair setup where red numbers never touch, you get a picture of the board in a few seconds.
Why use a fair or random layout?
The rulebook’s variable setup can still place two hot numbers side by side. Many groups prefer house rules that keep 6 and 8 apart. Fair mode does that for you, with optional extras like blocking identical numbers or matching terrain on neighboring hexes. Tournament mode turns all of those stricter checks on at once. Random mode skips the rules for a wild card table.

Balance score
After each roll you will see a simple balance score from 1–10. It nudges down when very high rolls sit next to each other, when identical numbers touch, or when the same terrain clusters. It is a quick read on how “spiky” the island feels—not an official tournament certification.
Tile counts (base game)
The classic island uses nineteen terrain hexes and eighteen number chits. Deserts never get a production number. The extension adds more hills, forests, fields, pastures, mountains, a second desert, and the extra chits that ship in that box.
