The casino, a modern form of the gambling house, is a massive building where people play games of chance and skill. Often, the most popular games include poker, blackjack and roulette. Slot machines are also a mainstay. The casinos are usually built in large resorts, but there are smaller versions that can be found in places like truck stops and bars. In addition, a growing number of states and tribes have legalized casino-type gambling establishments on land.
Casinos earn billions of dollars each year in profits for owners, investors and state and local governments. A large percentage of those profits come from gamblers, who spend huge sums on food, lodging and entertainment. A small portion of profits is also earned by the casinos themselves through a system known as the “house edge,” which means that the casino always has a slight statistical advantage over the players.
Something about the casino atmosphere seems to encourage cheating and stealing. That’s why casinos invest a great deal of time, effort and money on security. For example, dealers are trained to watch for blatant cheating, and tables are managed by managers who constantly observe patrons for signs of suspicious betting patterns or behavior. In addition, many casinos employ high-tech “eyes in the sky” to monitor the entire casino floor at once. These cameras can be directed to specific suspicious patrons by workers in a room full of banks of video monitors. The cameras also record all activities on the floor for later viewing.
