X-Scream ride is, at a height of approximately 866 feet (264 m), the world's third highest amusement ride, located on top of the Stratosphere Las Vegas. The name of the ride is a play on the word 'Extreme'.
Stratosphere Las Vegas (formerly Vegas World) is a hotel, casino, and tower located on Las Vegas Boulevard just north of the Las Vegas Strip in Las Vegas, Nevada, United States.
The property's signature attraction is the 1,149 ft (350.2 m) Stratosphere Tower, the tallest freestanding observation tower in the United States, and the second-tallest in the Western Hemisphere, surpassed only by the CN Tower in Toronto, Ontario. It is the tallest tower west of the Mississippi River and also the tallest structure in Las Vegas and in the State of Nevada. The hotel is a separate building with 24 stories, 2,427 rooms and an 80,000 sq ft (7,400 m2) casino. The Stratosphere is owned and operated by American Casino & Entertainment Properties.
While the traditional definition of the Strip excludes the Stratosphere, it is often included in travel guides as a Strip attraction. Using this alternate definition, the Stratosphere is the northernmost of the major Strip resorts, and is the only Strip hotel actually located within the City of Las Vegas.
