Basically, a casino is a place where certain types of gambling are performed. In the United States, there are over 1,000 casinos in operation.
Casinos in the United States generate billions of dollars in profit every year. Some of the games played at casinos include blackjack, baccarat, poker, craps, roulette, slots, and keno. Some casinos also specialize in inventing new games.
The casino’s business model is designed to make sure the casino is profitable. Using mathematically determined odds, the casino always has an advantage over the player. This advantage is commonly called the house advantage. Depending on the game played, the casino’s edge can range from 1% to 8%.
Casinos also employ specialized security departments that work closely with the casino’s assets to keep patrons safe. These departments are usually divided into a physical security force and a specialized surveillance department.
Casinos have elaborate security systems that allow surveillance personnel to watch the entire casino at once. The security department usually operates a closed circuit television system. These cameras can be adjusted to focus on suspicious patrons.
Casino employees watch patrons and keep tabs on betting patterns. Table managers also watch for blatant cheating.
There are also cameras placed in the ceiling of the casino to watch all of the windows. Some casinos have catwalks above the casino floor so surveillance personnel can look directly down at the casino floor.
In the past, casinos were illegal. However, real estate investors started running casinos without the interference of the mob. As a result, gambling became legal.
