The Joker's Jinx was asteel roller coaster atSix Flags America inPrince George's County, Maryland. The ride utilizeslinear induction motor technology to launch the train from 0 to 60 mph (97 km/h) in just over three seconds.
The Joker's Jinx was designed byPremier Rides and manufactured by Intermountain Lift, Inc.[2]
In the fall of 1998, pieces of greenPremier Rides roller coaster track were spotted on the park's property.[3] On October 28, 1998, it was announced that Adventure World would be renamed Six Flags America and feature three new roller coasters, including Joker's Jinx. Joker's Jinx would be an LIM spaghetti bowl launch coaster byPremier Rides. It was to be located in a brand new 6-acre (0.024 km2) Gotham City section, which would be entered by passing underThe Wild One roller coaster.[4]
Construction of Joker's Jinx began in December 1998 and was completed in late March 1999. On April 4, 1999, the ride performed its first test runs.[5] Joker's Jinx officially opened on May 8, 1999.
Joker's Jinx was repainted with a brighter green track in 2020.[6]
On May 1, 2025, Six Flags announced that the Six Flags Americapark will close at the end of the 2025 season on November 2, 2025.[7] The status on the future of the Joker's Jinx roller coaster was not given at the time of the announcement.[8]

Joker's Jinx is located in theGotham City section of the park nearSuperman: Ride of Steel roller coaster. After boarding Joker's Jinx, riders are launched through a narrow launch tunnel into a "spaghetti bowl" of track which contains acobra roll, a sidewinder, and many twists and turns. The coaster doesn't have a mid-coursebrake run like the similar rides atKings Island andKings Dominion; instead the coaster has multiple rings that the train goes through. After the rings, riders spiral downward and to the left, and after more twists and turns they pass through acorkscrew before arriving at the ride's final brake run.
Premier Rides built several of these LIM Catapult roller coasters from 1996 to 1999, although only the twoFlight of Fear rides are indoors. The other outdoor LIM Catapult coaster in the United States isPoltergeist atSix Flags Fiesta Texas; that opened in 1999. In addition, a LIM Catapult coaster called Mad Cobra operated atSuzuka Circuit in Japan from 1998–2003; Mad Cobra was moved to China and reopened at Kingdoms of Discovery in (2006-2026).[9][10] The five Premier LIM catapult coasters share a similar layout and have the same technical specifications.
Premier Rides gave thetrains an overhaul in 2002 and replaced the restraints with lap bars.[11]

On April 13, 2017, a train stalled 100 feet (30 m) off the ground at a 30-degree angle stranding 24 riders. They were evacuated safely, and there were no reported injuries.[12][13] The roller coaster was stuck in the same position it was in when a similar incident occurred in 2014, where it took more than four hours to evacuate the stranded riders.[14]
