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.
