Expansion for Bohnanza only available with the book "Das grosse Bohnanza Buch".
It adds 6 new cards to the game. Three of the Spiderbeans are orange, three are black. With this comes a new way of bluffing when you're trading the Spiderbeans.
When you harvest the SpiderBeans it's not just the number of beans that counts but more the way you planted them.
