Diamondback (Kings Island)

Mystic Timbers is a wooden roller coaster located at Kings Island in Mason, Ohio. Constructed by Great Coasters International and designed by Skyline Design, the roller coaster opened in the Rivertown section of the park on April 15, 2017. The ride's fictional theme is set to the site of an abandoned logging company where unexplained events are taking place. During its marketing campaign, the finale element in an enclosed shed was not revealed to the public until opening day. Mystic Timbers was voted "Best New Ride" of 2017 in the annual Golden Ticket Awards publication by Amusement Today. Its opening also allowed Kings Island to reclaim the title of having the most wooden roller coaster track of any amusement park in the world with 18,804 feet (5,731 m).

The Crypt was an indoor Giant Top Spin ride located at Kings Island in Mason, Ohio. Former park owner Paramount Parks collaborated with HUSS Park Attractions to design and manufacture the ride, which opened as Tomb Raider: The Ride on April 5, 2002. The flat ride featured a variety of special effects that correlated with the theme of the 2001 film Lara Croft: Tomb Raider from Paramount Pictures. Under new ownership by Cedar Fair, Kings Island removed all references to the film from both the ride and its indoor queue line following the 2007 season. It reopened as The Crypt in 2008. An outdoor, smaller version of the ride opened at sister park Kings Dominion in 2005 as Tomb Raider: FireFall and closed in 2019.

Woodstock Express is a wooden roller coaster located at Kings Island and designed by John C. Allen. It is located in the children's rides area of the park known as Planet Snoopy.

It has also been painted a number of different color schemes since its debut.

The Beast is a wooden roller coaster located at Kings Island amusement park in Mason, Ohio. Designed and manufactured in-house for approximately $3 million, the ride opened in 1979 as the tallest, fastest, and longest wooden roller coaster in the world. Decades later, it is still the longest, spanning 7,361 feet (2,244 m) across 35 acres (14 ha) of hilly terrain. Two lift hills contribute to the ride's duration of more than four minutes, which also ranks as one of the longest among roller coasters. A refurbishment in 2022 increased the angle of the first drop and lengthened the ride by 2 feet (0.61 m). The Beast was designed over the course of two years without assistance from scientific calculators and computers. Lead engineers Al Collins and Jeff Gramke consulted with well-known coaster architect John C. Allen, who shared design formulas and strategies to assist during development. Issues discovered during early testing delayed plans to build an enclosure over the helix finale until 1980. Ruth Voss, the park's public relations manager who would often overhear construction crews calling it "a beast of a project", is credited with coming up with the ride's name in early 1979. The record-breaking coaster was well-received at a press event preview held on April 13, 1979. Since its opening, The Beast has consistently ranked in the top ten among wooden coasters in the annual Golden Ticket Awards publication from Amusement Today. It has also earned a favorable reputation across the industry, including praise from American Coaster Enthusiasts (ACE), which held one of its first official events at Kings Island in 1979. ACE awarded the ride its Roller Coaster Landmark designation in 2004. After more than 40 years, it also remains one of the most popular rides at Kings Island, having accommodated over 54 million riders.

Scooby's Ghoster Coaster was a suspended roller coaster at Kings Island in Mason, Ohio. Opened in 1998, it was billed as the first suspended roller coaster in the United States designed for children. The ride is also the first in the country from Caripro Amusement Technology, a defunct company once based out of the Netherlands and later bought by Vekoma. Scooby's Ghoster Coaster was removed in the 2005-2006 off-season to make room for other rides during the area's conversion from Hanna-Barbera Land to Nickelodeon Universe.

Kings Island is a 364-acre (147 ha) amusement park located 24 miles (39 km) northeast of Cincinnati in Mason, Ohio, United States. Owned and operated by Cedar Fair, the park first opened in 1972 by the Taft Broadcasting Company. It was part of a larger effort to move and expand Coney Island, a popular resort destination along the banks of the Ohio River that was prone to frequent flooding. After more than $300 million in capital investments, the park features over 100 attractions including fourteen roller coasters and a 33-acre (13 ha) water park. Early in its history, Kings Island appeared in popular sitcoms and received widespread recognition for its record-breaking attractions and events. One of the park's most well-known attractions, The Racer, is often credited with reviving worldwide interest in roller coasters during the 1970s. The Beast and Banshee are among other attractions that have set world records, some of which are still held today. Kings Island's largest single investment is Orion, a giga coaster that opened in 2020 at a cost of $30 million. The park has also suffered through times of negative publicity, particularly surrounding the early demise of roller coasters The Bat and Son of Beast. Kings Island is divided into several themed sections and operates seasonally from early spring through the fall, partially reopening for Winterfest during the holiday season. In 2021, Kings Island had an estimated 3.18 million guests, ranking third in attendance among seasonal amusement parks in North America behind sister parks Canada's Wonderland and Cedar Point. In addition, Kings Island has won Golden Ticket Awards from Amusement Today for having the "Best Kids' Area" in the world for eighteen consecutive years (2001–2018) as well as "Best New Ride" in 2017 for Mystic Timbers.

The Bat was a suspended roller coaster located at Kings Island amusement park in Mason, Ohio. Designed by Arrow Development, it was billed as the "first of its kind" in the world when it opened to the public on April 26, 1981. The suspended coaster concept was a radical departure from traditional roller coaster design, where guests ride below the track instead of above. Previous attempts to build coasters that hang from the track were unsuccessful and date as far back as the early 20th century. Arrow solved issues by utilizing modern technology in the design, including its tubular steel track developed in 1959 for Disneyland's Matterhorn Bobsleds. Arrow constructed a working prototype in 1978 capturing Kings Island's interest, and their engineering department assisted with the development, construction, and maintenance of the ride. The Bat required 18 months of design and two years of manufacturing and assembly. The anticipation leading up to the reveal and opening was intense, as park officials disclosed very little while construction was taking place in view of park guests. Despite a successful launch and reception, the suspended coaster was plagued with mechanical problems and frequent closures over the course of its short lifespan. After a sporadic three seasons, the ride was permanently closed in 1983 and removed from the park. Arrow implemented improved banking and braking design in future installations that were more successful, such as Big Bad Wolf at Busch Gardens Williamsburg, which opened in 1984.

The Racer is a wooden, racing roller coaster located at Kings Island amusement park in Mason, Ohio. It was designed by John C. Allen, well-known for his contributions to roller coasters during the mid-twentieth century, and debuted at the park's grand opening in 1972. It was thrust into the national spotlight after being featured in an episode of the popular TV sitcom The Brady Bunch in 1973 and is often recognized for playing a vital role in the roller coaster renaissance of the 1970s. The Racer inspired similar designs in other roller coasters, such as Racer 75 (formerly Rebel Yell) at Kings Dominion and the now-defunct Thunder Road at Carowinds. The Racer is also one of the few original Kings Island attractions still in operation today.

King Cobra was a stand-up roller coaster located at Kings Island in Mason, Ohio. Manufactured by TOGO, the roller coaster operated from 1984 to 2001, and it was the first in the world to be designed from the ground up as a stand-up configuration. Other stand-up coasters that preceded King Cobra were sit-down models later modified to accommodate stand-up trains.

Delirium is the name of three Frisbee rides located at three Cedar Fair parks – California's Great America, Kings Island, and Kings Dominion.

The installation at Kings Island was designed by HUSS Park Attractions and opened on April 12, 2003, as the largest Frisbee ride of its kind in the world. The record-setting ride is able to swing 50 passengers up to 76 mph (122 km/h) reaching a height of 137 feet (42 m). Mondial manufactured the version of Delirium at Kings Dominion, which opened in 2016.

Vortex occupied the same location in the park once held by The Bat, the world's first suspended roller coaster. Tied to the coaster's debut, attendance at Kings Island exceeded 3 million in 1987 for the first time. It accommodated more than 46 million guests throughout its lifespan, making Vortex one of the most frequently-ridden attractions in park history. It closed permanently on October 27, 2019.
