- Six Flags St. Louis
Pandemonium is a steel spinning roller coaster designed by Gerstlauer, located at several Six Flags amusement parks in the United States. Since 2005, Six Flags has installed Pandemonium in five of its 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.
