These tips are from Wisco's Zoo Tycoon
* Guests can see in a range of 10 tiles. The more animals they see in this range, the better.
But these animals must be happy to keep the guests happy.
* Every animal house has different attractions. You can change the attraction of an animal
house by clicking on the house. This opens an info box. Then, click on an icon that looks
like a notepad. Note that these attractions must be researched first before you can use
them!
* The compost building generates $ 50 for every pile of raked poo. And if you have the
Dino Digs expansion, you will get $ 100 for every pile of raked dino poo!
* Every guest has his/her favorite animal. Seeing this animal in your zoo will increase
that guest's happiness! You can check a guest's favorite animal in his/her information
panel, by clicking on the guest.
* Don't hire maintenance workers in the first months of a game, because they will have
little work and you must pay them anyway! Also, don't start the game by building
food/drink-stands, because it takes a while before a guest becomes hungry/thirsty when
he/she enters your zoo. More important is it that you have to pay upkeep-costs for these
food/drink-stand, so you can save money if you wait to build the food/drink stands. The
same for restaurants.
* A hamburger stand is twice as filling as a hotdog stand but does not stimulate the thirst
as much.
