Beschreibung
Koi is a competitive set collection card game.

Introduction
You are a fish breeder who has been breeding Guppies and Minnows for fisherman to use as bait.  Recently you have decided that the real money is in breeding Koi, so you started to breed them in your Guppy and Minnow ponds.  You have figured out that 5 Koi gives you the right amount of genetic diversity without breaking the bank (because Koi are expensive).  You have also fallen in love with a certain color of Koi, and any Koi with this color is what you're after for your collection.  There's a problem though; your fish breeding neighbors have seen what you're doing and come to the same conclusion.  It is now a race to get to 5 Koi the fastest so you can start breeding and making money to buy out your competitors.

Object
To collect 5 Koi with the same color in your pond (hand) before everyone else. 
The color of Koi you collect is your choice and can be changed at any point during the game, as long as you end with 5 Koi that have the same color.
