Casinos are places where you can play games of chance, including poker, roulette, blackjack, craps, baccarat and more. They are popular with both gamblers and non-gamblers and provide entertainment, dining, shopping and more. Casinos are often located in vacation spots, like Las Vegas and Atlantic City, and also operate in other countries.

Casinos have become more than just gambling establishments; they have evolved into casino resorts that incorporate hotel rooms, entertainment and dining. They are one of the most visited tourist attractions in the world, with the largest casinos attracting millions of visitors annually.

Most modern casinos are designed with both a gambling floor and a non-gambling floor, with restaurants, bars, art galleries, convention space, theaters, hotels, swimming pools and more. Many offer players comps (free goods and services) based on how much they spend or how long they play at the tables or slot machines. These can include free rooms, meals, shows or even limo service and airline tickets.

With so much money changing hands, casinos can be a fertile breeding ground for cheating and stealing. Both patrons and employees may try to manipulate game results, either in collusion or independently. To combat this, casinos have elaborate security systems. Security cameras placed throughout the casino monitor game results and other activities, while electronic systems in table games track the amount of money wagered minute-by-minute and warn workers if any suspicious patterns appear. Computers are also used to monitor roulette wheels and dice, allowing casinos to quickly discover any statistical deviations from expected results.
