A Casino is a place where gambling activities take place. While lighted fountains, stage shows, lavish hotels and shopping centers help lure guests in, casinos would not exist without games of chance like slot machines, blackjack, roulette and craps. These games provide the billions in profits that casinos rake in every year.

Although some people do win at gambling, they are the exception rather than the rule. The reason is simple: casinos are not immune to the laws of mathematics and probability. It is almost impossible for anyone to walk into a casino and not lose money, at least in the long run.

Casinos make their money by offering a house edge to each game played. This advantage is small, less than two percent, but it adds up over millions of bets. Players who can eliminate the house edge by applying skill are known as advantage players.

While the mob ran many casinos in the past, large real estate investors and hotel chains with deep pockets have bought them out. They are eager to capitalize on the lucrative “destination” gambling business. Mob involvement in casinos is now extremely rare because of federal anti-mob efforts and the threat of losing a casino license at even the hint of mob interference.

Most casinos use sophisticated technology to monitor casino patrons and keep them safe. Video cameras watch every table, window and doorway. Roulette wheels are electronically monitored to discover any statistical deviation from their expected results. Some casinos use “chip tracking” systems that allow them to know exactly who is placing each bet minute by minute.
