A Casino is a building or large room where people can gamble. Its name is derived from the Latin word casino, meaning “house of chance”. Casinos are most commonly found in cities with legalized gambling. They can also be built near or combined with hotels, restaurants, retail shops, and other tourist attractions. In the United States, the most famous casinos are in Las Vegas and Atlantic City.

The games played in casinos generally involve a mixture of chance and skill. Some games, such as baccarat (in its French variant known as chemin de fer), blackjack, and video poker, are based mostly on chance; others, such as roulette and craps, involve a combination of luck and skill. Most casino games have a predictable long-term house advantage over the players, which can be calculated mathematically. Those who possess the necessary skills to eliminate this edge are called advantage players. Casinos profit from their gaming operations by charging a vigorish, or commission, on some or all of the games played within the establishment.

In addition to a variety of games, casinos often feature shows and other forms of entertainment. They may also offer food and drink, either free of charge or at a cost. Depending on the jurisdiction, they may be subject to government regulation and are required to submit financial reports. In order to prevent cheating and other irregularities, many casinos use technology to monitor the activity of their patrons. For example, betting chips have built-in microcircuitry that enables them to be tracked minute-by-minute, and roulette wheels are electronically monitored so as to quickly discover any statistical deviation from the expected result.
