There are various tricks employed by casinos to entice people to enter and gamble. The layout of the casino and the placement of slot machines and gaming tables in the halls are designed to appeal to the senses of sight and touch. The lights and noises from the slot machines are usually set to a constant C pitch to stimulate gamblers’ senses. While the overall design of the casino and its slot machines may be visually appealing, there is no one on the casino floor to watch the activity.
The word casino comes from an Italian word, meaning “little house”. The primary activity of a casino is gambling, but they can also include hotels, shopping malls, or restaurants. Some casinos even host live entertainment. The early meaning of the word “casino” is unclear, but it reflects how the activity has evolved. The casino was once used to entertain the rich and famous, but today it is an integral part of many communities. The first legal casino opened in 1765 in Baden, Switzerland.
Technology has increased the number of casinos and its ability to monitor games. Video cameras and computers now regularly supervise casino games, and “chip tracking” uses betting chips with built-in microcircuitry to monitor players’ bets minute-by-minute. Even roulette wheels are monitored and tested regularly to ensure they are fair and not biased against the house. Some casinos have also moved to an enclosed environment with games that can be played by pushing buttons rather than by dealing with dealers.
