Construction time
Do not spend coins to hurry construction. Instead, wait until you have to exit the game, then have the workers start on a new structure. Close the game, and allow the construction to progress while you are not playing.
Custom roller coasters
Save free tickets for creating custom roller coasters instead of completing tasks faster.
Don't remove what you can move
Early on, you may be tempted to cut away trees and shrubs, because they're in the way. Later your campaign, though, you may find that you miss the positive effects they have on customers. You're better off simply relocating the trees. Keep that same principle in mind as you advance. Your goal should always be to get the most out of every available resource, especially the ones that cost you money to build or replace.

Making your coins last
You'll never have to spend money on the game if you're smart about how you spend your coins and use your available resources. Since the game won't let you roll your device's time forward to shave off construction time, you're going to have to be patient while workers are adding structures to your park. It may be tempting to pay them to work faster, but a better option is to save time-consuming construction for later. Have the workers start on a new structure just before you close the game and leave to do other things, so that the building is completed when you come back the next day. If you are building coasters, make sure to design your own rather than working from preexisting templates, as that will also save you coins. Finally, remember to place as many booths and hotels as your park's guests will happily use, since those structures are one of the best ways to generate revenue.
Revenue
You can collect money from the front gate, attraction, or business at any time, without waiting for the coin icon to appear. Tap the building to collect its earnings. When building roller coasters, design your own instead of spending coins on templates. Place as many booths and hotels as your park's guests can use to generate revenue. Upgrade them whenever possible. In the "Build" screen, look under "Specials" to find the "Food Rush" event. Build it and use it to gain additional money and experience. It is a mini-game that pays you to flip burgers. Play it while waiting for other tasks, such as construction, to complete.
Rush to build food rush
In the Build section, check under Specials to find the Food Rush event, which you can build to give yourself easy access to additional cash and experience. You can play a mini-game that pays you for your time as you flip burgers, which is a great way to kill time while you're waiting for structures to materialize. Food Rush should be one of the very first things you build.
Trees
Do not delete native trees that are in your way. Move them out of the way, then place them back in your park later. Your guests will like them.
