A casino, or gambling house, is a place where people gamble by throwing chips at blacks and reds on roulette tables and poker games. Gambling houses are usually located in places with high levels of tourism, like tourist centers, resorts, hotels, and cruise ships. Most countries have laws regulating casinos.
A large part of a casino’s revenue comes from betting money on games with built in statistical advantages for the house (often less than two percent). The house edge is how casinos make their profit and allows them to build elaborate hotel structures, fountains, and replicas of famous monuments.
In the twentieth century casinos became more specialized in the types of games they offered, and the customers they attracted. Many began to offer more amenities, including restaurants, shows, and luxury suites. Most casinos now focus on “high rollers,” who are big gamblers who spend more than the average amount of money. Casinos reward these high gamblers with special privileges, such as free luxurious casino suites and personal attention. Less-frequent patrons are encouraged to join “comp” programs, similar to airline frequent-flyer clubs, in which they receive points that can be exchanged for free casino slot play and food or reduced-fare travel packages.
During the 1950s, organized crime money flowed into Reno and Las Vegas casinos, which were illegal in most states. Mobster money helped casinos overcome their seamy image and allowed them to compete with each other by offering more perks to gamblers. These perks included free spectacular entertainment, low-cost or discounted room rates, and complimentary drinks and cigarettes while gambling.
