A casino is a place where gambling games are played. While the modern casino has added a host of luxuries to lure customers, it still relies on gambling for most of its profits. Slot machines, blackjack, roulette, craps, baccarat and other games provide the billions of dollars that casinos rake in each year. The games of chance have been a part of human culture for millennia. Archeologists found dice in 2300 BC China and a game similar to blackjack first appeared in the 1400s.

Like any industry in a capitalist society, the casino business is designed to make money. Successful casinos rake in billions each year for their owners and shareholders, as well as local, state and Native American governments. In the United States, the casino industry contributes more than $1 trillion a year to the economy.

Casinos attract gamblers by offering free drinks, stage shows and other entertainment. Then, once the gambler is inside, they try to keep them playing by offering comps like free rooms and meals. Casinos also use their patron data to create mailing lists and target advertisements to specific groups of people.

Casino security begins on the casino floor, where casino employees keep a close eye on each game and each player. Dealers can spot blatant cheating, such as palming or marking cards. Pit bosses and table managers have a broader view of the tables, looking for patterns in betting that may indicate someone is cheating or just losing too much.
