A casino is a place where people gamble and play games of chance. It was first developed in the spa town of Baden-Baden, Germany about 150 years ago. Today, it attracts the wealthy and glamorous from around the world and is among the most lavishly outfitted casinos in the world.

Casinos are a business and, like any other business, they have to make a profit. Therefore, there is never any guarantee that a patron will win money at the casino. Almost every game in a casino has a built-in advantage that ensures the house will always be the winner, and this is known as the “house edge.” In addition, because of this virtual assurance of gross profit, casinos must regularly give large bettors extravagant inducements, such as free spectacular entertainment, luxury living quarters, limo service, and reduced-fare transportation.

Many casinos have special rooms where large bettors can gamble in privacy. In these rooms, the stakes can be in the tens of thousands. These big bettors are called comps (complimentary) and casinos often give them free hotel rooms, dinners, shows, and limo service.

The interior of a casino is designed to stimulate the senses and encourage the players to forget the passing of time. This is why casinos are often decorated in bright and sometimes gaudy colors and have no clocks on the walls. Moreover, they have carefully designed lighting, which is usually red to stimulate the senses and encourage betting.
