High Roller is a 550-foot tall (167.6 m),[2][3] 520-foot (158.5 m) diameter giant Ferris wheel on the Las Vegas Strip in Paradise, Nevada, United States.

Owned and operated by Caesars Entertainment, it opened to the public on March 31, 2014 as the world's tallest Ferris wheel.

[11] The outer rim comprises 28 sections, each 56 feet (17 m) long, which were temporarily held in place during construction by a pair of 275-foot (84 m) radial struts, prior to being permanently secured by four cables.

[18] Located on Las Vegas Boulevard, across from Caesars Palace,[7] construction was originally scheduled to begin in September 2011 with a late 2013 completion;[14] subsequently revised to early 2014.

[21] When High Roller opened to the public in March 2014, tickets for a single 30-minute ride, the time taken for the entire wheel to rotate once, cost $24.95 (daytime) and $34.95 (nighttime).
