Hire Einstein
To extend your research by leaps and bounds, find Guest #1 and rename him “E=MC2”. Then find guest #2 and rename him “E=MC3”. The two will meet and begin brainstorming. Shortly thereafter they will ask to be hired on as the park’s research developers. Say “yes” and pour your resources into the think tank. The following year, research and development will have grown by leaps and bounds. You will have all of the latest rides and nearly a billion dollars to spend!

Increase Park Rating
Though it is questionable ethically, it makes business sense... Maintain high park ratings by drowning all unhappy guests! (Click on a mad guest and use the pincer icon to place him in the water.)

Kill Everything
First, find guest 2374, rename him as "Timothy Mcveigh". Next, make him walk by an entertainer, drown him, find a slide, and watch for a big bomb to go down the slide. Then, all your rides will be deleted, all people gone, all land flattened, and you'll receive ten million dollars.

Maximizing Productivity of Shops and Stalls
Location is the key to maximizing profits! Here are a few business tips:
Don’t squeeze stores together. They will compete for customers and their prices will fall. Put shops and stalls near the rear of the park, NOT at the entrance. Once tired and hungry guests have walked all the way to the back, they will be more than willing to pay higher prices for snacks.

Receive A One Million Dollar Gift
To get lots of money for your park, close it down for one full year! Afterwards, a man dressed in a blue suit and holding a clipboard will give you a little “helpful money” ($1,000,000).

Retain Ride Popularity
To retain a scary ride’s popularity, simply delete a segment of track and replace it with the same thing. The guests will be fooled into thinking that the amusement has been improved and will continue flocking to it!

Remove Weeds without Mowing
To remove weeds without mowing the landscape, click on a construction button (like the leveling land button). Then click on a weed it will disappear!

Utopia at Mega Park
To unlock Mega Park, a scenario with a sprawling plot of land and no objectives, you must complete all other scenarios
