A casino is a place where a variety of games of chance can be played, and gambling is the primary activity there. While musical shows, lighted fountains and other attractions help draw in patrons, casinos would not exist without the games of chance like blackjack, roulette, poker, baccarat and slot machines. These games provide the billions in profits raked in by casinos each year. Casinos have taken on many forms, from the massive Las Vegas strip resorts to small card rooms in bars and restaurants. Even racetracks have adopted the concept, putting slot machine-type games on their facilities. Some casinos also operate on boats or barges on waterways and in other venues such as trucks stops, bars and grocery stores.
Regardless of how much money a patron spends in a casino, the house always has a mathematical expectation of winning. This is because every game has built-in advantages for the casino that are designed to ensure its profitability.
Because of this virtual assurance of gross profit, casinos are able to offer big gamblers extravagant inducements such as free spectacular entertainment, hotel rooms and limousine transportation. Less frequent gamblers are often given “comps” as well, which are free goods or services based on how much they spend. In a casino, these include free food, drinks and hotel stays; tickets to concerts and other events; and limo service and airline tickets. In addition to these rewards, casino owners spend a large amount of time and money on security. Casino security is very important because something about gambling seems to encourage cheating, stealing and other bad behavior by people who want to win.
