A casino is a gambling establishment, where patrons place wagers on various events and pay for the privilege to do so. A casino may also host live entertainment, such as musical shows and concerts. Casinos are found worldwide and often combine with hotels, restaurants, retail shops and/or cruise ships. They also feature many games of chance, including blackjack, roulette, poker and craps. Some casinos offer skill based games, where the player’s decisions can make a difference in the outcome of a game. Players who possess skills that eliminate the inherent long-term house advantage in these games are referred to as “advantage players.”
Until recently, casinos relied on the generosity of big bettors to stay in business. As a result, casino owners could afford to spend large sums on spectacular entertainment and lavish inducements for top bettors, including free show tickets, travel expenses and elegant living quarters. In the 1980s, real estate investors and hotel chains began acquiring casinos with deep pockets. These companies feared losing their gaming license at the slightest hint of mob involvement and were eager to distance themselves from gambling’s seamy image.
Today, modern casinos use technology to ensure their integrity. Among other things, casino operators employ a team of mathematicians to analyze the odds of different games. The analysis provides a mathematical expectancy of the house’s profit for each bet and enables the casino to monitor the games for irregularities. In addition, the computer chips used in slot machines allow a casino to track bets minute by minute and can detect any deviation from expected results quickly.
