A casino, also called a gambling house or gaming hall, is an establishment where people can gamble. Most casinos offer a variety of games and are located in cities or tourist destinations. People can also play games of chance online at regulated gambling sites.
Something about the excitement of gambling encourages cheating and stealing, especially when large amounts of money are involved. That’s why casinos devote so much time and money to security. Casino security starts on the floor, where dealers have a close eye on the action and can quickly spot blatant cheating like palming or marking cards or switching dice. Pit bosses and table managers have a broader view and watch for betting patterns that could signal cheating.
Most casinos make money by charging a “vig,” or a percentage of the total amount of bets, to players. This can be a small number, but over time it adds up and makes the casino a profit. It’s also why many casinos are built near or combined with hotels, restaurants, and other entertainment facilities.
In the 1950s, the mob poured huge sums into Reno and Las Vegas casinos. But federal crackdowns and the risk of losing a gambling license at the slightest hint of mob involvement drove the mobsters out of the business, and real estate investors and hotel chains bought out their interests. Nowadays, casinos are choosier about whom they allow to gamble and focus on customer service. For example, they give comps, or complimentary items, to high rollers who spend tens of thousands of dollars at a time.
