A casino is a gambling establishment that offers slot machines, table games (like poker and blackjack), and sometimes entertainment shows. To gamble in a casino, you typically need to be of legal age and follow the rules and regulations of the establishment. In order to protect their patrons, casinos have a multitude of security measures in place. These include money counting machines, alert staff members and cameras in every corner.
One of the biggest security concerns is fraud and theft. Since casino games have such slim margins, it takes a lot of people and careful attention to detail to keep a casino running smoothly. For example, pit bosses oversee the tables and can quickly spot a crooked dealer or a rigged dice roll. They also work in a count room where they keep track of the money brought into the casino, counting it as it comes in and out and noting any suspicious movements.
Casinos also use technology to monitor the integrity of their games. For example, some modern slots have chips with built-in microcircuitry that allow casinos to monitor the exact amount of money wagered minute by minute and quickly discover any statistical deviation from what is expected. Roulette wheels are also electronically monitored to quickly detect any deviance from their expected results.
In addition to relying on math and technology, casinos also employ a variety of psychological manipulation tactics to keep players gambling. For instance, casino floor managers strategically position games with a high house edge near the entrance and tuck away those with a lower edge in quieter areas. In addition, casino floors are covered in garish carpeting to make it difficult to walk without losing track of where you are.
