In an exciting duel with your opponent, you expand the settlements and cities of your principality.
Once the Settlers of Catan Card Game, now just the Catan Card Game, this is an elegant empire building game that I think is even more fun than the original boardgame. The latter has become a classic entry into the world of strategy boardgames, and this card version is just the thing for new players looking for a challenging, portable game. This rules summary is for both the basic game and the expansion rules that introduces themed decks.
Note: The latest version of this game, which has quite a few changes, is called The Rivals for Catan.
