Throw a disco party before leaving the game. A one-minute disco costs a single DiscoBux and will double your animals' earnings for short amount of time, as well as reset their sleep counters. By doing this, your animals will stay awake for as long as possible before you play with them next. The best time to throw a disco party is just before a large number of your animals is about to fall asleep. Collect tips from happy visitors while waiting for an animal to fall asleep. It is even possible to get a DiscoBux along with coins. Listen for the sound of a tip hitting the ground and collect it quickly before it disappears. Find escaped animals when notified by the zookeeper. Escaped animals will be marked with an exclamation mark over their head as you scroll through the enclosures. You will get cash or DiscoBux for finding them. Remain in the game, even if you are not on a rescue mission. This allows you to earn more coins and gives a chance for random events.
