Drag visitors to their requested enclosures. When a visitor has been to 3 attractions, a goal is achieved. Complete the required number of goals before time runs out to pass each level.
Don't leave visitors waiting, or they'll run out out of patience. Buy more time by giving them ice cream and popcorn.
When an enclosure needs to be cleaned or an animal fed, drag the right icon to that enclosure.
Hint: Take care of the visitors already in the zoo first to clear some space!
