The Settlers of Catan: The Great River
The Great River of Catan is an expansion for The Settlers of Catan. The expansion consists of a tile with three hexes and a river. Everything constructed alongside this river grants a gold point. Each three gold points are worth one victory point.
All the other rules are the same as the base game — except that you now need two more victory points to win the game. This expansion was originally only available as an insert in Games Quarterly Magazine.
