The biggest hotels on the Las Vegas Strip, including the Bellagio, Caesars Palace and Wynn, are colluding to overcharge visitors for rooms through an algorithm designed to maximize their profits, according to the lawsuit filed Wednesday in federal court in Nevada.

One of the most identifiable hotels on the Las Vegas Strip is the Bellagio Hotel, iconic for its spectacular fountain show and one of the top casinos in the world. The main building of the hotel features 36 floors, while the newly built Spa Tower adds an extra 33 floors to the property.
