RollerCoaster Tycoon

To keep a scary ride's popularity, delete a segment of track and replace it with the same item. The guests will be fooled into thinking that the ride has been improved and will continue going to it. If you change the color of any ride, guests will think it is a new ride and go on it more. When choosing a color for your roller coaster, do not pick green and orange. Guests will complain about it.

Build a roller coaster or a whoa belly tower. With the roller coaster, make it a power launch mode and make it fly off the track. Do not test it, just open. With the tower, build it up approximately three times and put it on full speed. Do not test it and people will fly off as they are on it. Make a shuttle loop roller coaster, have it power launched, with a speed of 60 mph. Create a large square of road. When guests walk on it, they will become stuck. When nobody is on a smaller square, delete it. When you have one or two of three squares remaining, build water on them to drown all the guests.
To score a fast kill on a guest, click on desired victim, then select the pick up tool (resembles tweezers). Move and drop the guest in water. Put some water in front of an exit to a ride. All people that get on the ride will drown. Put water or a pit directly under the exit so people fall straight it and die or get trapped. It is an easy way to keep people in your park.

Put a "No Entry" sign where you want guests. All your guests will rush into that location.

Rename a guest to Tony Day. This will make that guest hungry.

Successfully complete all levels to unlock the Mega Park.

Rename a guest to Chris Sawyer. This will make that guest become a photographer.

Rename a guest to Richard Tan. This will make that guest become a pickpocket.

In big levels such as Diamond Heights and Evergreen Gardens, build two to three Observation Towers. Less guests will become lost.

Enter RICHARD BRANSON as a guest name for a rich guest.

Create an incredibly long path that leads to nowhere. When you have lots of guests walking on the path, delete a square at the beginning so that if they try to go back they will find themselves trapped. They will be forced to do nothing but walk back and forth endlessly. Wait until they are exhausted and have to go to the bathroom. When they cannot stand it anymore, add a couple of benches, one bathroom, and one restaurant. Watch how desperate they are to eat, sit, and use the bathroom. When they have used the bathroom and eaten and rested, delete the benches, restaurant, and bathroom. Watch them suffer all over again. Repeat every so often. For added fun, have paths lead to each other haphazardly, so they do not know where they are going. Make the paths cover the entire park area. The guests will be thoroughly confused, tired, and miserable. Open up a single bathroom at the end of a long, winding, zigzag path after several guests are running around holding their stomachs. Wait until they are all hunched over with misery and fatigue, then suddenly put up a cotton candy or popcorn stand (but do not wait so long that you no longer have any funds remaining). Suddenly, you will see all the guests walking around with cotton candy and popcorn. During the game you may encounter objectives that require you to have a certain amount of guests. Use the following trick to have fun
during the process and torture your guests. To keep your guests, make a hole at the "Exit" station. All of your guests will fall into the hole and have no other option but to stay in your park. However, this will make your guests unhappy, hungry, etc. Raise a small area of land and put water all around it. Find the sickest guest in your park put them, on the land, and fill it up with entertainers. Build at least a 5x5 island with or without restaurants, bathrooms, stalls, etc. And after you do that, go through your guests, find some really mad ones, and put them there.
