The Riddler Revenge is a Zamperla Giant Discovery ride that pendulums riders at Six Flags Over Texas. It opened on May 28, 2016.
The giant circle swings in a pendulum motion while switching between clockwise and counterclockwise rotations. At the peak of the swing, riders reach a height of 146 feet (45 m) above the ground and experience weightlessness. The Riddler Revenge stands at 90 feet (27 m) tall but reaches a height of 146 feet (45 m) in full swing with an angle of 120 degrees from the center. The pendulum motion propels riders back and forth at 69 miles per hour (111 km/h).
