Pandemonium

Pandemonium is the name of four spinning roller coasters currently operating at four Six Flags amusement parks in the United States, those being Six Flags Over Texas, Six Flags St. Louis, Six Flags New England and Six Flags Fiesta Texas. A fifth installment of the ride also operated at Six Flags Discovery Kingdom from 2008 to 2012 until it was replaced by Superman: Ultimate Flight. Each of these steel coasters were designed and built by Gerstlauer, a German ride manufacturer, along with Werner Stengel. Since 2005, Six Flags has installed Pandemonium in five of its parks.
