World of Zoo will simulate a zoo, and players will care for 95 different species of animals, from 11 different families, and place it in one of the 20 exhibits.[2][3] The goal of the game is to keep the animals in the zoo happy, ways to do this include: feeding the animals, playing with the animals, and improving the animals exhibits.[5] Keeping the animals happy will result in hearts and tokens for the player, who can then redeem their hearts and tokens for food, tools, and new animals.[5]
Certain achievements can earn the player certain objects, for example: new species can be unlocked, or in-game awards earned.[3][5] One example of an in-game award is the player raising in status with one animal family, for the big cat family, awards range from, lowest to highest, "Junior Big Cat Handler" to "Big Cat Whisperer".[5]
If the player scares the animals too much, they can attack.
The game will also feature an "Animal Creator", a feature that allows players to create and customize animals' personalities and appearances similar to Spore; along with an "Animal Adoption Network" feature—another way players can add animals.[2][3]
