A casino is an establishment for gambling. The games available in casinos vary by location. Some are located in land-based venues, while others operate online. In addition to traditional casino games, most offer other entertainment options like restaurants, bars and nightclubs. Some also feature golf courses and spas. Some casinos are operated by tribal governments. In the United States, casinos are licensed by state regulators and often require a minimum age for entry.

The OED defines a casino as a place where people can gamble with cash or paper tickets, called chips, on various events with a random outcome. It also refers to the machines that support these activities, and to the dealers or croupiers who conduct them. There are three general categories of casino games: gaming machines, table games, and random number games. Gaming machines are mechanical devices that can be played by one player at a time, and do not involve dealers or other staff. Table games include blackjack, roulette and craps. Random number games use a computer to select random numbers that correspond to symbols or positions on a game board.

While gambling is fun, it can also become a problem. To reduce the risk of becoming addicted, it’s important to manage your bankroll, and to set limits on how much you will spend. You can also make use of support resources, such as the National Council on Problem Gambling and each state’s hotlines or self-exclusion programs.
