Compare this to something like a 2, 12 and 11 intersection, which will only collect resources 1/9th of the time.
The second important factor is the numbers on each space. When rolling two dice not every result is equally likely – numbers towards the middle of the distribution such as 6 and 8 are much more likely than numbers towards the edges, such as 2 and 12. Some versions of the game have dots on each numbered tile – these represent the odds of rolling that particular number. There are 5 ways to roll a 6 on 2 dice, so the 6 tile will have 5 dots on it. You will want to place your initial settlements on intersections with high odds – such as a 6, 5, and 9. This intersection has a total dot value of 13, which means you will gather resources more than ⅓ of the time. Compare this to something like a 2, 12 and 11 intersection, which will only collect resources 1/9th of the time.
