Dsc Z's gl s smpl. Go on safaris and get animals for your zoo. Go in the game as many times as you can to ensure that your animals is not asleep. If the animals go to sleep, they won't earn any coins for you. Waking them up requires only a tap and they will get coins for you until they fall asleep again. If you want to earn coins faster and make animals wake longer, upgrade the level by rescuing more and more animals. If you don't have anything to do or are saving up coins for a new aircraft. The game's premium currency is the Disco bux. Unlike other games, it is surprisingly easy to find. If you want to go anywhere in the zoo without wanting to scroll, use the map. You should save up for disco bux because you can start a disco party which earns you 2 times more coins than normal and keeps animals awake.
