Unlike other forms of gambling, such as playing online slots, a casino has a lot of social interaction. Players are typically surrounded by other players when playing slot machines, and alcohol is often readily available. Nonalcoholic drinks are also often available at no extra charge. Casinos are also designed with light, noise, and excitement in mind. Many high rollers receive luxury suites and lavish personal attention. The casinos spend a great deal of money on security measures to keep their patrons safe.
Security in a casino begins on the floor, where employees monitor the games and patrons. Dealers, for example, focus their attention on the game they’re playing and may not notice if a patron is cheating. Pit bosses and table managers also keep an eye on the tables, looking for suspicious behavior. Security cameras are also commonplace at casinos to keep employees accountable. They also monitor and report any suspicious behavior to higher-ups.
In the early 1990s, casinos increased their use of technology, including video cameras and computer systems. Casinos also introduced “chip tracking” systems, which allow them to monitor wagers minute by minute. Roulette wheels, for example, are constantly monitored for statistical deviations. Some casinos have even built enclosed versions of games, so that players can play the games with just a few clicks of a button. These developments made the casino experience more enjoyable for its customers and lowered the house edge.
