A casino is an establishment for gambling. Some casinos offer traditional games such as blackjack and roulette, while others have more elaborate attractions such as themed buildings, hotel suites, top-notch restaurants, and spas. Some casinos also host live entertainment events. Casinos have come a long way from the days when miners chasing gold in the Wild West took breaks to play poker in local saloons. Today, casinos are massive and luxurious complexes that feature a variety of games and amenities to appeal to gamblers of all ages.
Gambling likely predates recorded history, with primitive protodice and carved six-sided dice appearing in archaeological sites around the world. But the casino as a place to find a wide variety of ways to gamble under one roof didn’t really develop until the 16th century, when a gambling craze swept Europe. Aristocrats often held private parties at places called ridotti, where they could gamble and drink to their hearts’ content without fear of being bothered by the authorities.
Modern casinos use a range of sophisticated security technologies to prevent cheating and other illegal activities. Cameras in the ceiling provide a high-tech “eye-in-the-sky” view of the entire casino floor, and they can be adjusted to zoom in on specific suspicious activity. Dealers and table managers keep an eye on patrons to make sure they aren’t attempting any blatant cheating (palming, marking or switching cards, for example).
And while it may be difficult to spot a crook when everyone else is so focused on their own game, casino security people are trained to look for subtle patterns in the way players act and react. For example, the regular patterns of chip placement on a blackjack table can reveal attempts to hide chips under the table or to change their betting pattern from usual.
