Mindbender
The second of two vertical loops is shown here at the bottom of this picture. However, the park makes the bewildering claim that Mindbender has three loops. They count the diagonal plunge, or tilted helix turn, seen at the top of this picture as a loop. I don't know of any coaster enthusiast who agrees with Six Flags' statement that this was the first coaster with three loops!
