When people think of casinos, they often picture bright lights, big money and a chance to win. But it\u2019s not just slot machines, blackjack and poker that bring in billions of dollars to US casino owners each year; other games like keno and craps are also popular. From the glitz of Las Vegas to tiny mountain towns with 19th century Wild West buildings packed with tables, casinos are all over the country and the world.<\/p>\n
In the twentieth century, casinos became more selective about who they let gamble in their establishments. High rollers\u2014gamblers who place large bets and spend long periods of time playing slot machines\u2014are a casino\u2019s main source of revenue. These players get special treatment, including comps such as free hotel rooms, meals and tickets to shows. They are often invited to play in special rooms away from the main gambling floor, where their bets can be in the tens of thousands of dollars.<\/p>\n
Casinos have also proven to be very good for local economies, especially when they are located in communities that lack other major economic sources of employment. Tax revenues from casino gambling help pay for community services and can also reduce unemployment rates in the immediate area.<\/p>\n
