There are several ways to ensure the security of a casino. Many casinos are protected by software that uses routines and patterns to run their games. The dealers deal cards and shuffle them, and the betting spots are always marked on the table. This makes it easier to detect anyone who is acting in an unusual way. The house edge, or the percentage of money a casino makes from every bet, is very important to consider. The higher this number, the lower the house’s expected profit margin.
The first layer of protection comes from the employees of the casino. These individuals are always on the lookout for cheaters, but their focus is on their own game. There are also table managers and pit bosses who monitor all of the tables for betting patterns. All of these individuals have someone in higher positions to keep an eye on them. The results of these measures help to ensure the security of a casino. There are also special cameras that help the employees in spotting suspicious behavior.
Today, casinos use technology to make the gaming experience more convenient and safe. Some use computers and video cameras to supervise the games. “Chip tracking” involves betting chips that have built-in microcircuitry to keep track of each wager minute by minute. Roulette wheels are regularly monitored and analyzed for statistical deviations. Some casinos have even created enclosed versions of games that don’t have dealers. Instead, players push buttons to place their bets.
