A casino (also known as a gambling house or a kasino) is an establishment for certain types of gambling. It is also a place where people can watch live entertainment such as stand-up comedy, concerts and sports. Some casinos are combined with hotels, restaurants and other tourist attractions.

A large percentage of the games played in a casino are based on chance. There are some that require a high degree of skill. The casino industry is heavily regulated and monitored by governments worldwide. Casinos are generally classified into three categories: gaming machines, table games and random number games. Gaming machines are operated by computer programs, such as slot machines or pachinko. Table games, such as baccarat or blackjack, are operated by croupiers or dealers. Random number games are based on the selection of numbers by a random number generator or other casino equipment.

Many casinos offer perks and rewards to encourage gamblers to spend more money than they intended, or to keep them gambling for longer than planned. These can include free drinks, hotel rooms and show tickets. Some casinos also have golf courses, spas and other entertainment.

Most American casinos are located in urban areas. Most are heavily regulated by government agencies and have high security. Many are owned by major gambling companies. Some, like Las Vegas and Atlantic City, are famous for their glitz and glamour. Others, such as WinStar World Casino and Resort in Oklahoma, have a more refined tropical theme.
