Overview

Catan Junior is a simplified version of Settlers of Catan with a pirate theme. Players build pirates’ lairs and ships on a fixed island board, collecting resources when islands produce goods. A Ghost Captain blocks production, and Coco the parrot provides helpful bonuses. The first player to build all 7 of their pirates’ lairs wins.
