A casino is a public place where gambling games of chance are played. Aside from the actual gambling, casinos usually include restaurants, bars, shops, spas and even museums under one roof. Casinos draw in people with their glitzy appearance and promise of winning big money. But what really goes on in these glass-and-steel temples of temptation? This article takes a closer look at how casinos make their billions (and keep you hooked), the history behind the most popular gambling games, and the dark side of the industry.

Security is a huge component of a casino. Casinos have to be very careful about cheating and stealing because of the large amounts of cash handled within them. This is why many casinos use security cameras throughout the building. In addition, casinos employ special staff members called spies to watch over different areas of the casino. These individuals have a much wider view of the operations and can easily spot a player who is trying to cheat by palming cards or marking dice.

Casinos also offer free goods and services to “good” players, known as comps. These are given for a variety of reasons, from free drinks to hotel rooms. Players can also receive limo service and airline tickets if they spend enough time playing. In exchange for these perks, the player gives up some of their winnings to the casino. The casino then adds up the total value of the player’s bets and divides it by the number of hours the player plays. This percentage is the casino’s advantage over the player and is known as the house edge.
