The Riddler Mindbender, previously named Mind Bender, is a steel roller coaster located at Six Flags Over Georgia near Atlanta, Georgia. Billed as "the world's first triple-loop roller coaster" when it opened on March 31, 1978, Mindbender has maintained its popularity since its opening. In its 30th anniversary season in 2008, Mindbender was ranked #15 by Amusement Today magazine in its annual Golden Ticket Awards, and was one of only two roller coasters built before 1980 on the list; the other was its "fraternal twin," Shockwave, at Six Flags Over Texas.
