A casino is a gambling establishment where patrons place wagers on games of chance, or games with an element of skill, for prizes or cash. Some casinos focus solely on gambling while others offer hotels, restaurants, bars, non-gambling game rooms, and entertainment. The largest casinos in the world are located in China and the US.

The primary source of revenue for a casino comes from a percentage of bets placed by gamblers, which is known as the house edge. The house edge varies by game and by state. Generally, the higher the house edge, the more money the casino makes. In some games, the house edge is a fraction of one percent, but in others it is much higher.

Something about the large amounts of currency handled in casinos encourages both patrons and staff members to cheat or steal, either in collusion with each other or independently. Because of this, most casinos spend a great deal of time and effort on security measures. These range from simple cameras to highly sophisticated “eyes-in-the-sky” systems that watch every table, window and doorway at once.

To keep their edge, casinos make special concessions to high rollers (gamblers who place large bets). These may include free hotel suites, expensive dinners, tickets to shows, and limo service. In exchange, these gamblers typically give up some of their winnings. In the 1970s, most Las Vegas casinos employed this strategy to fill rooms and attract customers.
