Delirium

Delirium is a Giant Frisbee ride located in the Action Zone section of Kings Island. It opened on April 12, 2003, and has been operating for over fifteen years at the park. The ride was manufactured by HUSS Park Attractions, who had previously manufactured the defunct Tomb Raider: The Ride (later renamed The Crypt) and Shake, Rattle, and Roll(formally called Troika).

History
After the defunct Tomb Raider: The Ride(later renamed The Crypt) opened in 2002, park officials at Kings Island were impressed with the ride's popularity, and brought HUSS Park Attractions back a second time to make a new ride. HUSS designed a new Giant Frisbee, which improved on their original Frisbee design by featuring an increased number of seats, a longer pendulum, and a higher swing of 120 degrees. This design was eventually used for Delirium, and became the largest Frisbee ride at the time of its opening.

Ride Experience
The queue line features a roof that provides not only shade, but also protection from any objects that could potentially fall from guests while riding. It also gives the illusion that the ride is about to fall onto the area, before it swoops upwards for its swinging pattern.

Riders are given a number shortly before they reach the end of the line, corresponding to the seat they will occupy while riding. Once everyone is onboard, the ride begins, and the pendulum starts to swing, with the ride platform rotating. This allows for a different experience each time the ride swings, offering a different view of the surrounding area. After making several swings, the ride begins to slow down, and once the ride platform comes to a stop, the guests are allowed to exit.

Trivia

 * A similar ride opened at sister park Kings Dominion in 2016 under the same name, and features a similar color scheme, but the primary difference is that it had a different manufacturer.
 * This was the third ride in the park to be manufactured by HUSS Park Attractions. The first ride was Shake, Rattle, and Roll (formally called Troika), and the second was the now closed Tomb Raider: The Ride (later renamed The Crypt).
 * This was the first ride that debuted during the 2003 season at Kings Island. The second was SpongeBob SquarePants 3D in the now-closed Action Theater. Also Scooby Doo’s Haunted Castle opened in 2003(now known as Boo Blasters on Boo Hill)
 * In the 2013-2014 off season the ride was repainted red, white, and orange; therefore removing the checkered spot on the ride.
