One of the most obvious ways that casinos ensure the safety of patrons is to have elaborate surveillance systems. Casino security personnel watch every corner of the casino, including tables, windows, and doorways. These cameras are adjusted to focus on suspicious patrons, and video feeds are recorded for later review. Casinos also enforce strict rules regarding the display of cards and cash. Players must always keep their cards visible while playing card games. In addition, casino employees are strictly prohibited from using cell phones while inside the casino.
In addition, casinos have a built-in statistical advantage. The casino’s edge can be as low as two percent. However, millions of bets make up enough money for the casino to maintain a competitive edge. This advantage, known as rake or “vig,” varies from game to game. The higher the advantage, the more money the casino keeps. But the higher the house edge, the better for the casino. That’s why casinos are more likely to reward good players with comps and other perks.
Gambling addiction is a serious problem for many people. Casinos are not only expensive, but they also create enormous disproportionate profits for themselves. Research shows that about five percent of American casino patrons are addicted to gambling, and they contribute about 25 percent of their revenues. However, despite their enormous profit margins, casino addictions reduce the value of casinos for their surrounding communities. In addition to taking away people’s money from local businesses, casinos often cause the corresponding loss of productivity.
