A casino is an establishment for certain types of gambling. These facilities are often combined with hotels, restaurants, retail shops, and/or cruise ships. The term may also refer to a place where people watch horse racing or other sporting events. In the United States, casinos are generally licensed and regulated by state governments. In many cases, a casino’s profits are taxed.

Casinos are staffed by gaming employees known as croupiers or dealers. The croupiers deal cards to players and oversee other casino activities. Casinos may also offer table games, such as blackjack and craps. These games are usually played against the house rather than against other players, although they may be conducted in tournaments. Casinos may also feature random number games, such as roulette or baccarat.

In the United States, there are more than 1,000 casinos. Las Vegas is the largest casino city, followed by Atlantic City and Chicago. In addition to regulated commercial casinos, some states allow Native American tribes to operate casinos on Indian reservations, which are not subject to state gambling laws.

While it is possible for casino patrons and staff to cheat or steal, these incidents are relatively rare. Due to the large amounts of money involved, casinos employ numerous security measures. In addition to physical security measures, such as cameras and secure entrances, casinos also enforce rules of conduct and behavior for their employees and patrons. These measures are intended to prevent people from stealing or colluding with each other to gain an unfair advantage over the casino.
