Sandbox allows players to create a zoo with their own imagination without any restrictions in terms of money. By accomplishing several levels, players are able to unlock new objects which would be available through the rest of the gameplay. The further they proceed, the more complicated the level is, which would involve some strategies in order to fulfill the task. Campaign Mode includes several levels in which players are required to complete the goals each before processing into a harder challenge. There are 3 different modes: Campaign, Challenge & Sandbox. In Zoo View, they can carry out their constructions and adjustments whereas they are able to walk around in the zoo, take care of the animals by themselves and clear the trash when in Guest View. Furthermore, players can run across into two modes, Zoo View and Guest View. Once they are enjoyed and so the animals, the zoo will profit more and its reputation will increase. Food & drink stands are also essential to satisfy their hunger & thirst as well as restrooms and entertainment kiosks which will amuse them. So keeping guests happy is very important other than animals by providing benches to sit, trash cans to reduce littering on the floor and donation bins in every exhibit for them to donate.

Moreover, guests are not happy even though they spot happy animals when there is lacking of kiosks, restrooms, scenery and entertainment, leading them to leave the zoo immediately with unhappiness and the zoo will gain less profit. Animals are unhappy if they are poorly treated or have their demands not met, hence will try to escape from their enclosures and frighten guests away in the zoo. The objective of this game is to build a successful zoo by building enclosures to accommodate various animals and keeping them happy.
