What Is a Casino?


A casino is a place where people can gamble on games of chance. It can be large and luxurious or small and plain. In general, however, a casino will offer a wide variety of gambling games and provide food, drinks and entertainment. Casinos are a significant source of income for the companies, corporations, investors, and Native American tribes that own them. They also generate billions of dollars each year for the state and local governments that regulate them and tax them.

Gambling is a risky business. There’s no such thing as a sure thing, and the odds are always in favor of the house. A successful casino will be able to take advantage of this fact and maximize its profits. The way it does this is through built in advantages that give the casino a slight advantage over customers. These advantages, called the “house edge,” can vary from game to game but are generally lower than two percent.

Something about casinos seems to attract people who want to cheat, steal or scam their way into a jackpot. That’s why casinos spend a great deal of time and money on security. Casino employees watch the patrons closely and look for recognizable patterns in their behavior. Casino managers and pit bosses supervise table games with a broader view, checking for blatant cheating such as palming, marking or switching cards and dice. In addition to security staff, many casinos employ a variety of technology to monitor the activities of the patrons and the games themselves. For example, casino chips have a microcircuit that allows the casino to monitor the amount of money wagered on each hand minute-by-minute; roulette wheels are electronically monitored to discover any statistical deviations from their expected results.

Casinos are also designed with features that help keep people playing for longer periods of time. This includes things like a lack of windows and clocks, which prevent players from realizing how long they’ve been gambling or how much money they’ve spent. Those factors, combined with the excitement of the gaming floor and the lure of free drinks, can add up to a lot of money lost for the average gambler.

Before Nevada legalized casino gambling in 1931, organized crime mobs controlled the major casinos of Reno and Las Vegas. The mobsters had plenty of cash from their drug dealing, racketeering and other illegal activities and had no problem with gambling’s seamy reputation. However, federal crackdowns and the risk of losing a gambling license at even the hint of mafia involvement eventually made legitimate businessmen cautious about getting involved with casinos. As a result, many of the early casinos were owned by mobsters or by hotel and real estate developers with close ties to mob figures. The mobsters, in turn, used the casinos to launder their money. As the industry matured, mob involvement faded, and casino ownership shifted to real estate investors and hotel chains with deep pockets. Even so, mob influence can still be felt in the design and management of some casinos today.
