Catan Resource Probability
A precise tool.
What is the Catan Resource Probability & How does it work?
Settlers of Catan uses two six‑sided dice, so each possible sum has a well‑defined probability based on the number of combinations that produce it.
When a number token is placed on a hex, the probability that the hex produces its resource on any given roll is the dice probability multiplied by the share of that resource among all resource‑producing hexes.
By combining the dice odds with the board layout you can estimate how often a particular resource will appear, which is essential for optimal settlement placement.
E = frac{c_n}{36} times frac{T_n}{T_{total}}
E = expected probability of receiving the selected resource on a single roll

Frequently Asked Questions
How do I calculate the probability of a specific resource appearing?
Multiply the dice probability by the share of that resource among all resource-producing hexes.
What are the possible sums when rolling two six-sided dice in Catan?
The possible sums range from 2 to 12, with 7 being the most likely outcome.
How does the board layout affect resource probabilities?
The placement of number tokens on hexes and their adjacency to settlements or cities influences how often resources are produced.
Can I use this calculator for any board setup?
Yes, you can adjust the calculator for different board layouts by changing the resource distribution and token placements.
What is the importance of knowing resource probabilities in Catan?
Knowing these probabilities helps players make strategic decisions about where to place their settlements and cities for optimal resource gathering.
How do I interpret the dice probability chart?
The chart shows the frequency of each possible sum from two dice rolls, with 7 being the most probable (1/6 chance).
