Uwe Rosenberg seems to have a talent for inventing novel card game systems, and this game helps his reputation. Some describe it as Bohnanza, the second helping, and in this game about collecting sets of different kinds of jewelry players do buy cards from each other and play cards out of their hands to complete sets of four. However, the points awarded for a complete set are adversely affected if multiple sets of similar cards already exist.
In BRIDGE TROLL, you and your friends are hideous trolls who each guard a troll bridge. Each turn, you throw boulders to bid for travelers, who vary in number depending on the weather for that day.
Travelers include fat merchants, pilgrims, poor monks (who make good eating), and if you are lucky, royal personages.
