What Is a Casino?

A casino is a gambling establishment, or “gambling house”, that offers customers the opportunity to gamble by playing games of chance and, in some cases, skill. These games of chance include dice, slot machines, table games such as blackjack and baccarat, and card games like poker. In addition to these games, some casinos also offer sports betting and lottery-type games. The most recognizable of these establishments are in Las Vegas, Nevada, but they can also be found in other cities around the world and on cruise ships.

Gambling has been part of human civilization for millennia. Archaeological evidence of the first games of chance dates back to 2300 BC China, while dice appeared in Rome about 500 AD and card-based gaming became widespread in Europe in the 1400s with games such as baccarat.

Today, most casinos are built near or combined with hotels, restaurants, retail shops, and other tourist attractions, and many of them feature entertainment such as stand-up comedy shows, concerts, and sporting events. Many states have laws regulating the operation of casinos, and some jurisdictions prohibit them altogether.

It is important for casino operators to understand the business model behind their businesses and the economics of each game they offer. For example, they need to know the house edge of each game and its variance. To calculate these numbers, they use the services of mathematicians and computer programmers known as gaming analysts. These figures determine the gross profit (or loss) that the casino expects to make from each patron.
