Evolutionary Bohnanza-variant
Design: Uwe Rosenberg
© Lookout Games 2001 in a limited edition of 2500 copies.

Bohnanza is published by Amigo, Germany and available in English by Rio Grande Games.
The layout of this translation follow the original German rules, but the text has been expanded and in some cases clarified for ease of understanding.

Game Materials
In the Bohnanza-variant "MUTABOHN" may different sorts of bean cards be planted in the same field. The box contains 33 Bonus cards and 4 pages of rules in German. The cards contains 7 different pics which have no influence on play, they are flavor only. The top corners show 24 different combinations of bean types, and these may have one of three Bonus values:
10 cards of 30 Bohnenpfennige
11 cards of 50 Bohnenpfennige
12 cards of 70 Bohnenpfennige

Game Preparations
A copy of the Bohnanza is needed to play "MUTABOHN". Any language edition will do. You do not need the expansion for the two-player game, and the variant may be played with more players using only the basic cards by following the guidelines at the end of the rules, but the game will be easier to play if you have the the listed cards from various expansion (see below).
The preparations follow the standard rules. In addition are the Bonus cards 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.

Cards Needed
  # of players
2-3+The cards from the basic game are used with any number of players.
4+Add 22 Weinbrandbohnen
(or the 22 Kognakbohnen from the 2001 edition of "High Bohn".
  5+  Add 24 Kaffebohnen.*
6+Add 26 Wachsbohnen, but remove the 6 Gartenbohnen.**
7Add 28 Mokkabohnen, but remove the 6 Gartenbohnen.**

*) A game will take about 1 hour with the original Bohnanza-end game rules, and about 2 hours if played with the Mutabohn-endgame rules.
**) The game ends when the deck has been depleted 3 times - as by the original rules.

Game Idea
The 4 types of mutationsNot only Soybeans can be untenable manipulated geneticly to make them more durable, more nutricious or whatever. Other types of beans may be manipulated as well. In "MUTABOHN" will the beans 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.
Important: All beans in a field will be regarded as being of the same type as the last planted bean, and when harvested will the payout be as stated on that card. Example 1
EXAMPLE 1: Anni has collected 2 Brechbohnen (frequency 14) in a field, and now she is planting a Saubohne (16) and a Feuerbohne (18) directly on top of them.
All four beans are now considered to be "Firebeans" and if she collects two more will they be worth 2 Gold.
Even if she only had one other Feuerbohne card could she plant that plus a Blaubohne (or two "Blue beans") and still cash in 2 Gold.
OBS! You cannot buy a 3rd Field in "MUTABOHN"!

Bonus Cards
Each Bonus card feature a series of icons in the upper right and left corners showing a pattern like AABBC. Small colored pictures are used instead of the letters A, B, C (and D) are they form a "gene-code" which should be identical to the beans in the field in order to benefit from the bonus. NOTE: The gene-code is always targeted towards the last placed card. A code with 5 bean icons will thus target the last 5 cards in a field. No other cards in that field have relevance for that bonus.
AABBC means that the field must contain two beans of one type, then two beans of the type which is slightly less rare (the next higher frequency), and finally must the fifth bean be of the type which is one step more common: always the next higher number in frequency. It is important to remember that the beans planted must always be of the same type or of the next higher frequency. "Skips" are not allowed, so you cannot plant a Brechbohne (14) directly on top of a Augenbohne (10) since you would have skipped the level with the Sojabohne (12). Example 2
EXAMPLE 2: A field containing the cards Rote Bohne, Augenbohne, Augenbohne, Sojabohne Sojabohne, Brechbohne would fit the Bonus card with the gene-code AABBC:
The "Red bean" is not counted, "A" = Augenbohne, "B" = Sojabohne and "C" = Brechbohne.
The field would also fit the Bonus card with the gene-code ABBC.
The Bonus card AABB could NOT be used as the last played card is a single bean. If another Brechbohne was planted could the 7 cards not only be harvested for 4 Gold, but this Bonus card could be played as well.
The Bonus cards held the player's hand tells him which Gene-codes he should be looking for. Whenever the player has a field with the corresponding Gene-code may he - at any time - show the Bonus card and add it to his pile of money.
The value of the Bonus card is written on the card.
100 Bohnenpfennige = 1 Bohnentaler (1 Gold).
A player will immediately draw a new Bonus card as replacement as soon as he has played one, so that he always has two Bonus cards in his hand. Each Bonus card will only come in play once per game, so when the pile has been depleted will a player not be able no longer be able to refill his hand. Since Bonus cards can be played at any time may a dispute arise about who has the right to the last card. If the card is claimed by more players at the same time will the card be given to the player who is sitting first in the player-order.
Important: You do not have to harvest the field when you cash in your Bonus card. You simply place the card in your money pile and draw a new card. This card may be shown and cashed in immediately if the Gene-code fits one of your fields. This way can several Bonus cards be cashed in from the same field.
Special rule: A player may at any time pay a Gold (one of the regular Bean cards from his money pile) to be allowed to exchange one or more Bonus cards from hand with new from Bonus pile. The returned cards are placed in any order at the bottom of the pile, and the same number of cards are drawn from the top. This rule is particular important in the two-player game as the Bonus deck contains many cards which may be of better use that those held right now.

The Game Turn with Two Players
The two-player game follow the standard phases with the new rules for planting added (see "Game idea" above) and changes to phases 2 and 4.
Each player has 3 Bonus cards in hand instead of 2 in the two-player game.
OBS! In the two-player game may each player use his Bonus cards on cards planted in his opponents fields as well as his own.
Phase 1: This part of the game turn is unchanged:
You must plant the first card in your hand, and you may plant the second.
Phase 2: After the active player has revealed the two top cards of the deck must he offer a Bean card to his opponent. This can either be one of two Beans just revealed or any Bean card from his hand. The offered "gift" must be accepted by the other player unless he can return the favor by making a counter-offer in the form of a card from his own hand. This exchange of offers will continue until one player cannot (or do not want to) make a legal offer:
Important: Each type of Bean may only be offered once (per phase).
If player A offer a Blaubohne may player B not offer a Blaubohne in return.
If he makes a counter-offer with a Feuerbean, may player A in return offer a card which is neither a Blaubohne nor a Feuerbohne.
The first player who is unable to offer a legal gift will receive a fine of 1 Gold. The fine is temporarily marked by placing a "3rd Field" card in the player's money pile. This card is deducted from the player's score at the end of the game.
After the exchange of gifts will the phase continue with the normal trading.
The players may, if they agree, play the game without forced trading.
Phase 3: The third part of the turn is unchanged. The newly acquired Beans are planted in the player's fields in the order decided by the player. First will the active player plant his Beans, and then will the other player plants his. It is important to plant the Beans one at a time, in order to give the opponent a chance to play his Bonus cards.
Phase 4: Draw new cards according to the table below. The game ends as soon as the draw pile is empty. The deck is not reshuffled.

 Two-player game:
 0-2 beans in hand  draw 3 cards 
 3 or more beans in hand  draw 2 cards 


The Game Turn with More Players
The multiplayer game have the following changes to the basic game of Bohnanza:
Phase 1: The active player must plant the first two Bean cards in his hand.
In addition he may plant his 3rd card.
A player who doesn't have at least two cards in his hand at the beginning of his turn, will receive a fine of 1 Gold. The fine is temporarily marked by placing a "3rd Field" card in the player's money pile. This card is deducted from the player's score at the end of the game.
Phase 2: No change. Reveal the 2 top cards of the deck and trade as nornal.
Phase 3: Since the traded Beans may be planted in any order may a player have several options to cash in Bonus cards. Contrary to the two-player game may a player only cash in Bonus cards for his own fields. The new rule for planting Beans in effect (see "Game Idea").
Phase 4: At the end of his turn will a player draw new cards according to the tables below:
 3-4 player game:
 0-2 beans in hand  draw 4 cards 
 3 or more beans in hand  draw 3 cards 

 5-7 player game:
 0-2 beans in hand  draw 5 cards 
 3 or more beans in hand  draw 4 cards 

Table explanation: As can be seen will a player be rewarded with an extra Bean, if he ends his turn with two or less cards in his hand.

The Alternative MUTABOHN Game Ending
The original Bohnanza-rules state that the game ends as soon as the draw pile has been played through 3 times. With the new "MUTABOHN"-rules will the game be far from finished at that stage.
3-4 players: The game ends with the new Mutabohn-rules.
   5 players: The players may use either type of ending.
6-7 players: The game ends by the standard Bohnanza-rules.
The draw pile is reshuffled as many times as possible. Whenever the draw pile is depleted will the discard pile be reshuffled. IMPORTANT: The card-mixer should ask all players in turn order, beginning with the current player (and including himself), whether they want to harvest one or both their fields to include more cards into the deck. The ending may thus be postponed for a long time.
The cards in the deck and discard pile may be counted at any time, including when it is being reshuffled.
The game may end after phase 3 (a) or in phase 4 (b).
a)The game will end after phase 3 when a player cannot reveal two cards in phase 2, IF both the draw and the discard piles are empty and no player is willing to bring cards back into the game by harvesting. The game will end after the current player has finished phase 2 and 3 - regardless of the size of the discard pile after phase 3.
b) The game ends immediatly during phase 4 when a player cannot draw the cards required and no player is willing to harvest to bring more cards into play.

Final Scoring
Each player harvest his last fields and count his Gold (Bohnentaler and Bohnenpfennige). Once again: 100 Bohnenpfennige = 1 Bohnentaler.
The player with the most money wins the game.

MUTABOHN without the Bohnanza-expansions
If you don't have the recommended type of Beans can you prolong the game using the following rule: For each missing type must all earned Bohnentaler-cards be returned to the deck once when the discard pile is reshuffled. The players will keep their earned Bonus cards and fines. The game is played with the "MUTABOHN"-ending.
EXAMPLE: The five friends Julia, Rick, George, Tim and Anni wants to play "MUTABOHN" but they don't own any of the other expansions, and thus must play without the needed Weinbrand and Kaffeebohnen. They must play through the deck twice, and each time must they write down their score on a piece of paper and return their earned Bean cards to the deck. The third time the deck is depleted (and any subsequent rounds) may the player keep their Gold as normal.
WARNING! This variant is a stressful - not to say exhausting - trading game. Most Beans offered will have several potential buyers. This demands sharper negotiations and the whole game loses some of its "lightness".
