There is more to a casino than meets the eye. Casino security begins on the floor, where employees keep watch over patrons and games. Dealers keep their focus on their own game, so they can spot signs of cheating. Table managers and pit bosses watch over the table games, looking for patterns in betting and cheating. Each employee has a superior who tracks them. It’s important to be aware of any signs of cheating in a casino.
Today, casinos use a variety of technological innovations to keep players safe and entertained. Computers and video cameras routinely supervise games. In some cases, players bet with chips with built-in microcircuitry, allowing casinos to track wagers minute by minute. Casinos also monitor roulette wheels for statistical deviations. Many casinos offer enclosed versions of games, where players bet by pushing buttons. This reduces the need for dealers. However, there is no substitute for the human touch.
American Indian reservations have no antigambling laws, which allows casinos to operate. In fact, many states have amended their gambling laws to allow casinos. Puerto Rico and South America also have casinos. The Havana casino closed in 1959, and today, there are estimated to be over 3,000 legal casinos in the world. The legalization of casinos has facilitated their growth across borders. A large percentage of all states now have at least one casino. The number of casinos worldwide has reached over 3,000.
