Casino is an establishment for certain types of gambling. It may be combined with hotels, resorts, restaurants, retail shops, cruise ships or other tourist attractions.

Casinos draw millions of visitors from around the world. Las Vegas and Atlantic City are probably the best-known examples, but there are casinos in many cities. Many people also play casino games at home, through online gaming sites or in state-licensed gambling clubs.

Although casinos have added luxuries like restaurants, music and stage shows to attract patrons, the bulk of their profits still come from games of chance. Slot machines, blackjack, poker and roulette are among the most popular games in casinos. Craps, keno and baccarat are less common but also provide billions of dollars in casino profits each year.

While something about gambling encourages players to cheat, steal or scam their way into a jackpot, casinos spend a huge amount of time, effort and money on security. In addition to a physical security force, most modern casinos have specialized departments that monitor casino games for statistical deviations from expected results.

In addition, casinos often reward gamblers who spend large amounts of time and money with free goods and services, such as hotel rooms, meals and tickets to shows. The most profitable gamblers are called high rollers and receive comps worth tens of thousands of dollars. Casinos are able to track this high spending and give these players special treatment, such as private rooms.
