The most famous casinos in the world offer a mix of glamour, history and top-notch accommodations. While some are more famous than others, they all share a certain je ne sais quoi that draws people in from across the globe.

The one thing that casino patrons can be sure of is that the house will always win. The house edge, or the expected gross profit from all games offered, ensures that it is impossible for any individual game to make a profit. With so much money on the line, it is no wonder that something about gambling encourages cheating and stealing—either in collusion with fellow gamblers or by individuals who aren’t part of a syndicate.

To help deter these activities, casinos have many security measures in place. These can include cameras that watch every table, window and doorway, and can be adjusted to focus on suspicious patrons. Another important measure is comping players. These are free goods and services offered to “good” customers (those who play for long periods of time or at high stakes). Examples of comps include hotel rooms, dinners, tickets to shows and even limo service and airline tickets.

With so many competing casinos, it is crucial that a casino stay on top of its marketing strategies. By using tried and true methods, a casino can ensure its future and attract a new audience.
