Fibonacci card games
are
games of chance and skill for up to four players
using a special deck of cards. They are "draw and
discard" rummy style games. The objective is to form
the cards in one's hand into sets putting them face
up on the table in "melds", to be the first player
to complete six sets and then to "go out" with no
cards left over. Players score by completing melds
and by going out. The game can also be played
Solitaire. Several different games can be played
with the one card deck.
There are 89 cards in Fibonacci Deck
21^{©}
and, except for three wild cards and two bonus
cards, each card is identified with one of six
numbers in the Fibonacci series, specifically: 2,
3, 5, 8, 13 and 21 as shown in the picture to the
left. The numbers in a completed set of cards have to add to
21. A set can be simply one card, (card 21) or as
many as eight cards for example: 2, 2, 2, 3, 3,
3, 3 and 3.
A unique feature of the Fibonacci
series is that each number is equal to the sum of
the two preceding lower numbers. For example 5 = 3 +
2, and 21 = 13 + 8. It is this feature,
in combination with the rules, that makes the
Fibonacci rummy game
challenging and unique.
Certain cards in the deck are
designated as "base cards". Each set must start with
a base card except for the single card set 21.
The number on the top left corner of a base card is
red and two rabbits can be seen on top of the
colored area. A bonus card for base 2 (see the
bottom right corner card opposite) includes two
number 3's making this card total 8.
Each card has graphics associated
with the card number. The heights of the colored
rectangles and the colored areas on each card are
proportional to the Fibonacci number. The number 21
card is colored 100% from top to bottom and is 3.5
inches high. The number of petals on the flower in
the center of the card is equal to the Fibonacci
number.
The colored areas on card
combinations that add to 21 would exactly fill a
single card. Cards can be stacked and overlapped on
top of each other, the bottom of one card to top of
the colored area on another card, as a visual aid to
set collection.
The card on the left is a wild
card, the Fibonacci card. The picture is of Leonardo
Pisano Fibonacci, the 13^{th} century
mathematician. Fibonacci showed that the number
series answers a question as to how a rabbit
population grows. See
"About Fibonacci".
The Fibonacci card can be used as a base
card or in a set. The player has to designate the
number which the card represents but can change the
designation as the game progresses.
