Modern casinos have elaborate security systems, including video cameras and computers. Casinos also monitor patrons and games through “chip tracking” technology, which involves betting chips that contain microcircuitry. The casinos can keep track of their wagers minute by minute. Routinely monitored roulette wheels can detect unusual betting patterns and be inspected for possible cheating. Most casinos also have enclosed versions of many games, which do not require dealers and allow players to make their bets by pressing a button.
Many casinos reward their “good” players with comps. The comps are based on length of stay, stakes wagered, and other factors. Many players are superstitious and dislike the thought of casinos trying to change their luck. However, if the casino wants to make more money, they can change the dealers to “cool” the game. The player might even resent the change of dealers, believing the new dealer is skilled at a variety of “cooling” tricks.
Although compulsive gambling is harmful for a person, casinos benefit from it. The money generated by problem gamblers contributes to disproportionately high profits for them. According to studies, five percent of all casino patrons are addicted to gambling, generating 25 percent of the casinos’ profits. Economic studies have also shown that casinos have negative economic impacts on local communities. Although casinos largely draw local players, their presence diverts spending from other local activities. The economic gains from casinos are offset by the costs of treating problem gamblers and the lost productivity that results from gambling addiction.
