A casino (or casino) is an establishment for certain types of gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shops, and cruise ships. Some casinos are also known for hosting live entertainment events. The term casino may also refer to an automated machine for gaming purposes, such as a slot machine or video poker.

Some casinos are famous for a single attraction or activity, such as the Bellagio Fountain show in Las Vegas, which has been featured in many movies and television shows. Others are notable for their luxury hotels, spas, or restaurants. Some are famous for their poker rooms and attract professional players, including celebrities.

In the United States, a casino is a facility that offers table games such as blackjack, roulette, and craps, and is operated by one or more live croupiers. It may also offer other types of gaming, such as poker tournaments and sports betting. The casino makes its profit by taking a portion of each bet or charging an hourly fee for the use of tables and machines.

A casino can be distinguished from a card room by its specialized staff and security measures. Casinos also employ rules and regulations designed to deter cheating, such as requiring that cards be visible at all times. In addition, some casinos employ pit bosses to monitor the behavior of patrons and enforce the rules. Other security measures include the use of cameras and other surveillance equipment.
