Pandemonium is a spinning roller coaster located at several Six Flags theme parks in North America. It was designed by Gerstlauer, a German ride manufacturer, along with Werner Stengel. Since 2005, Six Flags has installed Pandemonium in five of their parks. Its design consists of several cars holding four riders each. While the cars traverse the track, they spin around according to the angle of the track and the shifts in the riders' weight.
