Mutabohn is an expansion for Bohnanza released in 2001 for 2–7 players, 60 minutes per game, and ages 12 and up. It was designed by Uwe Rosenberg and its main mechanics are Hand Management, Set Collection, and Trading.
This expansion for Bohnanza was published as a limited edition of 2500 copies. Mutabohn allows different sorts of beans to be planted in the same field. The box contains 33 Bonus cards and 4 pages of rules in German. The cards contains 7 different pictures which have no influence on play, being flavour only. There are 24 different combinations of bean types, in three Bonus values (30, 50 and 70). The Bonus cards are shuffled and placed as a pile face down next to the draw pile. Each player receives 2 Bonus cards (3 cards in a two-player game). The Bonus cards are placed anywhere in the hand, they do not follow the strict order of the Bean cards. In Mutabohn, genetic manipulations allow the beans to mutate while they are growing in the field. Gartenbohnen may become Rote Bohnen. Rote Bohnen may become Augenbohnen, etc. Each bean type can be transformed into the next lower value (which has the next higher number of cards) simply by planting this new type of bean on top of the old beans. Each Bonus card features a series of icons in the corners showing a pattern like AABBC (Small coloured pictures are used instead of letters) --this forms a "gene-code" which must match the pattern of beans in the field in order to play the bonus. Expands: Bohnanza Mutabohn is part of the Bohnanza family of games.
Mutabohn supports 2–7 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Mutabohn is 60 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Mutabohn for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Mutabohn has a complexity rating of 2.2 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
