A casino is an establishment for certain types of gambling. These include blackjack, roulette, poker and slot machines. In addition, some casinos host live entertainment such as concerts and stand-up comedy. Casinos may also have restaurants and bars. Many are located in or combined with hotels, resorts and other tourist attractions. In some cases, they are operated by government-licensed organizations. In the United States, there are over twenty states that allow commercial gambling, and some offer multiple forms of gambling. These include lotteries, instant games, sports betting and horse racing, as well as table games such as baccarat and craps.

Something about gambling attracts people who like to cheat, scam and steal, or at least try to do so. This is one reason why casinos devote much time, effort and money to security. Many modern casinos use video cameras and other technology to oversee the games. In addition, most of the newer table games have built-in microcircuitry that interacts with electronic systems in the tables to track and oversee the exact amounts wagered.

Although the casino industry varies by country and jurisdiction, there are some common features. Typical casinos are large and elegant, with a focus on visual appeal. They often feature rich colors, lighting and decor that create a stimulating and cheering environment. They tend to cater to high-stakes gamblers and offer a variety of gambling options, from poker to high-rise slot machines. They also offer luxury hotel rooms and spas, fine dining and other amenities.
