The casino’s appeal lies in its ability to draw the attention of players with sound and light. The machines are designed to entice the sense of sight with flashing lights and a rhythmic noise. The smell of cigar smoke and a smoky ambience attract the sense of smell as well. Drinks are easily accessible with waiters circulating throughout the gaming floor. Nonalcoholic drinks are available, too.
Gambling probably predates recorded history, with primitive protodice and carved six-sided dice found at archaeological sites [Source: Schwartz]. However, the modern casino as a place where people could find a variety of ways to gamble under one roof didn’t develop until the 16th century during a gambling craze in Europe that led to the creation of small social gathering spots called ridotti.
Casinos are businesses, and like any business they need to make a profit. To do this, they offer games that have built-in advantages for the house that help it win a percentage of all bets placed. These built-in advantages are known as the house edge, and they ensure that the casino will always come out ahead in the long run.
Unlike other forms of gambling, which are often seen as harmless pastimes, casinos have a negative impact on the communities they serve. Studies indicate that local patrons are more likely to be addicted, which erodes the economic benefits of casino gambling and costs taxpayers with higher treatment and productivity losses [Source: PBS]. In addition, casinos harm property values in surrounding neighborhoods.
