RollerCoaster Tycoon

Click on a guest and leave it on for a long time. He will get very angry.

Rename a guest to Simon Foster. This will make that guest turn into an artist.

If you accomplish the mission on the level that you are on, and if you have a balloon stall, when your guests clap they will all drop their balloons and have to buy another one.

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. To get more people to buy from stalls, build a waiting line to the stand instead of a path. People will be mistake it for a ride. Note: Only use one stand per line.

Click on construction, delete everything until the end of the first loop, and make a flat piece. Then, add an on-ride photo section. Make it go up and add another loop. Next, make it go at the highest angle and click on the short turn at the top. Build about four to six of these and set the launch speed at 50 to 58 mph. This should make you over $2000 an hour and barely costs any money or time.

Before you complete a mission go to a location that has a lot of guests. When the mission is over they will all start to clap.

Place handymen outside roller coaster exits. Click on the handymen and the press the small blue footprints. Click the area you want them to stay in. This makes for a much cleaner park.

Simply place a new pathway over a dirty path to quickly clean it. To quickly clean your park without using more money to replace the path that is dirty, select one of your handymen. Even though it might not be as fast as just replacing the path, drop them wherever there are empty cans and vomit piles. This also works for emptying the garbage.

Open a ride and as soon as it is full, double click on close to get the money the guests paid for the ride. When your park has enough money to afford all of advertisement campaigns, put all of them on. Then, hike the entry price to $50. Crowds will come swarming in because of the advertisements and will pay $50 to enter. This will result in quick and easy money. When in Dynamic Dunes go to the Dynamic Blaster roller coaster. Set the price to $3, wait until you get a very long line, then hike the price up to about $10. Every person in that line will have to pay $10 to ride. Note: Using a higher price may cause everyone to leave the line.

Did you know that if your vertical Gs on any roller coaster are too high they won't go on?

The U.S. limit is 3.0 Max vertical Gs, which I think the game has. If a ride has more, all guests will say "Its too extreme for me".
