Catan Online is a strategic board game that takes inspiration from "Settlers of Catan", which made its debut in 1995. In this game, players assume the roles of settlers on an island and compete to construct and expand settlements, trade resources, and accumulate points. The game board is modular and can be arranged in various configurations, making each game unique. Players need to use their resources wisely and negotiate with others to get what they need, as the winner is the first to reach a certain number of points.
