Fibonacci 21

Fibonacci 21 is a deck of 89 cards numbered 2, 3, 5, 8, 13, or 21. Several rummy-style games and a solitaire game can be played with the deck. The idea in each game is to form sets of cards based on the Fibonacci sequence and then to meld those cards onto the table. The winner is the first player to go out after acquiring the correct number of sets.
