A Casino is a place where people can gamble, and sometimes win large sums of money. However, the casinos are renowned for being unclean, with many people cheating and scamming. Because of this, casinos spend a lot of money on security and protection. In most cases, the people who gamble will never see the money they win. To avoid this problem, casinos are required to use special anti-cheating measures to keep their premises safe.
The American version of roulette has a house edge of 5.26%. In other words, the casino expects to make less than $1 for every $1 million bet. The French version of roulette, known as trente et quarante, is more popular with small bettors. American casinos tend to take a greater percentage, and roulette attracts big bettors while craps is a favorite of big gamblers. However, in America, casinos demand a much higher percentage of profit than in France.
To protect their casino from cheaters, casinos install elaborate surveillance systems to monitor everyone. The cameras on the ceiling monitor every table and window, while video feeds are recorded for later review. Likewise, the payouts from slot machines are determined by computer chips embedded into the machine. With so much information available, casino security is not as difficult as it used to be. However, to keep their patrons safe, casinos employ a number of employees who work behind the scenes to ensure that everyone is following the rules.
