Categories (Catan x factor)
The Catan x.. categories, indicated in the Game Library, show how easy/difficult a game is to understand/explain. So we use Settlers of Catan, as a reference. Games as easy/difficult as Catan are indicated by Catan x1. Games with Catan x.1/2 are easier and Catan x2 and Catan x3 more difficult. These categories also each have their own color.
The colored stickers on the boxes indicate which category the games belong to, how many players the game can be played with, the minimum age and the average playing time.
