The word Casino, as it is used in the United States, refers to a public establishment where a variety of games of chance can be played. While many casinos offer luxuries such as restaurants, free drinks and stage shows, the vast majority of revenue and profits come from gambling. Roulette, blackjack, craps and baccarat, among other popular games of chance, generate the billions of dollars in profits that casinos rake in every year.
In addition to attracting gamblers with flashy lights and noise, casinos make use of technology to supervise the games themselves. For example, roulette wheels are electronically monitored minute by minute to discover any statistical deviations from expected results. And, in a technique called “chip tracking,” betting chips have built-in microcircuitry to interact with electronic systems at the table and enable casinos to see exactly how much money is being wagered in each game moment by moment.
Casinos also employ a wide range of tricks to keep players gambling. Slot machines, for example, are designed to appeal to human senses of sight and touch, and their sounds are electronically tuned to the musical key of C to be pleasing to the ear. And, recognizing that humans are attracted to bright objects, casinos drape their buildings with more than 15,000 miles of neon tubing.
New casino games are released regularly, and many online operators update their game libraries frequently. Some even have a page dedicated to their latest releases.
