Give as good as you get in Bohnanza: The Duel!
What was that thing about the gift horse? In this two-player variant of Bohnanza, both bean farmers give each other gifts of beans they can't use themselves — to make life harder for their opponent, if possible. Trying to fulfill their secret "bo(h)nus" requirements, they both need to keep a vigilant eye on the other player's bean fields.
In more detail, both duelists have bean field mats in front of themselves on which to plant their beans. Between them is a row of eight gift cards. Each player holds five hand cards and three "bo(h)nus cards" with secret objectives. In this game, you have the option of planting more than one type of bean in the same field, but when you plant a different bean than the one you've planted previously, this new bean type must be the next highest number. When harvesting your beans, the beanometer of the card you've most recently planted is what counts.
