A casino is a facility for certain types of gambling. Often, casinos are combined with hotels, resorts, restaurants, retail shops and cruise ships. Some are also known for hosting live entertainment and theater productions. Some famous casinos are the Bellagio in Las Vegas, the Venetian Macao and the Rio.
Gambling has been a part of human culture for millennia. The earliest evidence of gaming was in China in 2300 BC, followed by dice in 500 BC and then card games like baccarat around the 1500s. Today, more than 51 million people visit casinos domestically and worldwide.
Many casinos are crowded with high rollers who gamble and drink heavily. These high rollers usually have their own rooms away from the main floor and are pampered with food, drinks and other amenities. Some even get complimentary suites. Casinos make most of their money from these wealthy players and thus rely on them for their profits.
Casinos have super-high security to protect their patrons and property. Most are heavily regulated and audited by government agencies. They also employ super-trained staff who monitor and spot suspicious behavior. They also have elaborate surveillance systems with cameras that can watch every table, window and doorway in a building. They can even zoom in on a specific patron or game. The cameras are connected to banks of security monitors in a control room where casino workers can adjust the focus. Casinos are a major source of revenue for their home cities and generate many jobs.
