Each player is a zoo owner. Players score points by attracting as many visitors to their zoos as possible. To accomplish this, they must collect matching sets of animals. If a player manages to obtain many animals for his zoo, he will find it worthwhile to expand his zoo. Once all the enclosures are occupied, newly acquired animals must go into the barn. Vending stalls next to an enclosure guarantee a minimum number of visitors. At the end of the game, a player loses points for animals they have left in the barn. The player with the most points wins the game.
