Build a Zoo is a Roblox tycoon simulator experience developed by Century Farmers. Players build and manage their own zoo by purchasing mysterious eggs from a conveyor belt, hatching them to reveal animals of varying rarities, and collecting coins generated by their collection. The core loop revolves around reinvesting earnings into bigger enclosures, rarer eggs, and a more impressive zoo.
The game features a pet fusion system that lets players combine multiple animals to create stronger companions with unique traits. Special weather events like the Black Mist can grant pets rare Shadow Mutations, adding a layer of random reward to progression. Seasonal content brings exclusive pets, titles, and season pass rewards on a rotating basis.
Build a Zoo is structured around escalating rarity and collection depth, appealing to players who enjoy egg-hatching and idle tycoon mechanics common in the Roblox genre.
