A casino is a gambling establishment that offers games of chance. In addition to traditional table games such as blackjack, roulette and craps, some casinos also offer video poker, slot machines and other electronic gaming devices. Some casinos are integrated with hotels, resorts and restaurants, while others are freestanding buildings. Some states prohibit or restrict gambling.

A modern casino typically has a physical security force and a specialized surveillance department. The security forces patrol the casino and respond to calls for assistance or reports of suspicious or definite criminal activity. The surveillance department operates the casino’s closed circuit television system, which is known as the “eye in the sky”. These departments work together to ensure the safety of both guests and the casino’s assets.

Gambling is big business and casinos exist in almost every country in the world. The United States leads the world with 2,147 licensed casinos and 619 casino hotels. Many of these are located in Las Vegas, Nevada. In the 1980s casinos began appearing on American Indian reservations, which are exempt from state gambling laws.

One of the best-known casinos in the world is Caesars Palace in Las Vegas. This iconic landmark is Roman themed and has hosted the likes of Frank Sinatra, Liberace and Elton John over the years. Another well-known casino is the Venetian in Macau, China. This spectacular casino is the biggest in the world by square feet. It features a variety of table games and slot machines as well as high-end dining and accommodation options.
