Most casinos throughout the world have restrictions on who can legally gamble. The general rule is the age of majority, depending on the country that may mean age 16 to 21. Casinos are in the business of making money. The hotels, shopping, entertainment and restaurants only bolster the attraction to a particular venue. The majority of the profits that casinos realize come from the gaming industry of gambling. The casinos do not exist for the sole purpose of providing their customers with an income through winnings. Each gambling game whether a game of chance, skill or event outcome (as in sports), has a predetermined, mathematically calculated outcome. All of which favour the gambling casino. This is the "House edge", which all casinos maintain. Gambling casinos like to keep their customers happy to ensure they keep coming back, to spend more money. They accomplish this with giving casino bonuses and "comps", free items such as entertainment tickets, meals and drinks or reduced hotel rates. The extent and value of these comps are dependent on the amount of time and money a customer is spending in the casino gambling. And believe it or not there is also a mathematical equation that casino gambling staff use to calculate the amount of comps a customer is to receive.
The dark side of the casino gambling culture is crime and the arguable association. With the influx of large numbers of tourists to casino gambling centres, with large amounts of cash on hand, the free flow of alcohol with only fun and entertainment in mind. The same scenario would draw those that would take advantage of the less aware or impaired. Crime statistics vary depending on whose numbers you use. The gambling casinos say their numbers show no evidence of any crime increase. While others might disagree. All things considered, there can be no argument at the popularity of casino gambling games.
