Klunker (1999)

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.
