A casino is an establishment for certain types of gambling. Casinos are often built near or combined with hotels, restaurants, retail shops, cruise ships, and other tourist attractions. Some casinos also serve as convention centers. In the United States, the term casino can refer to any of several types of gambling establishments: a standalone facility, an integrated resort, or a gaming room in a hotel or other property.

Depending on the jurisdiction, casinos can also offer a wide variety of games. In the United States, most casinos feature traditional table games such as blackjack, roulette, craps, and baccarat. Many of these games are conducted by a live dealer, while others use a random number generator (RNG). The term casino can also refer to online versions of these games.

Because of the large amounts of money handled within casinos, both patrons and staff may be tempted to cheat or steal. As a result, most casinos have security measures in place to deter this activity. These measures may include cameras, security personnel, and rules of conduct and behavior. Casinos that rely on the RNG for their games must also have mathematicians and computer programmers who analyze the random number data to detect anomalies that indicate attempts at cheating or fraud.

In addition to offering a wide selection of casino games, some casinos have impressive theater venues that host a variety of entertainment acts. For example, the Hard Rock Casino in Vancouver is famous for embracing its rock and roll heritage and regularly hosts concerts by popular musicians.
