A casino is a facility for certain types of gambling. The modern casino is much like an indoor amusement park for adults, with the vast majority of its entertainment (and profits for the owners) coming from games of chance. Slot machines, black jack, roulette, craps and keno provide the billions of dollars in profit that casinos rake in every year.

Something about casinos seems to encourage cheating and stealing. That’s why casinos devote a lot of time and money to security. But how do casinos keep their patrons safe, and what are the dark sides of this lucrative business?

Casinos have come a long way since the early days of gambling. As disposable income increases around the world, casino tourism is booming. The world’s best casinos are trying to capture this growing market by offering luxury accommodations, exotic entertainment and exciting games of chance.

The best casinos are designed to impress, with lofty gold-trimmed ceilings, crystal chandeliers and white-tablecloth restaurants. The interior design has some specific goals, including keeping the patrons comfortable and making them forget that time is passing.

Many casinos also reward their high-spending patrons with comps. These free goods and services are based on the amount of money you spend at the tables or slot machines, and can include everything from free hotel rooms to dinners, tickets to shows and even airline tickets. Just ask a casino employee for details. As a result, casino businesses have to be careful not to give too much away to people who can’t afford to keep gambling. Otherwise, they risk losing their licenses to operate.
