A casino is a gambling establishment where customers place wagers on games of chance and skill. These games can include table games such as blackjack, roulette and poker, as well as video slots and other electronic machines. Casinos also offer dining, entertainment and luxurious accommodations.
Gambling has been part of human culture for millennia. Evidence of it exists from as early as 2300 BC, when Chinese blocks were found with symbols on them; dice appeared in Rome around 500 AD and the game now known as poker came into being in the 1400s. Today, casinos take a variety of steps to encourage patrons to spend more money and reward them for their loyalty. These include free food and drinks, a wide variety of games (some with an element of skill), and special rooms for high rollers who gamble in the tens of thousands of dollars.
Modern casinos are equipped with a variety of technological tools to help them keep track of their patrons and prevent cheating or crime. For example, slot machines have computer chips that determine payouts and can be adjusted to focus on particular suspicious patrons. Similarly, cameras in the ceiling provide a high-tech “eye-in-the-sky” to monitor every table, change window and doorway and alert security personnel when something unusual occurs.
Casinos are heavily regulated by government and are usually owned by large business organizations, such as hotel chains or real estate developers. In the past, mobster control of casinos was common, but federal crackdowns and the threat of losing a casino license at any hint of Mafia involvement have forced many mob families to divest their interests.
