A casino is a place where people can gamble on various games of chance. Many casinos have a wide variety of entertainment offerings in addition to gambling, including restaurants, free drinks, stage shows and dramatic scenery. The largest casinos are often called resorts and have multiple hotels, restaurants and many gambling tables and machines. These casinos are the most famous and often have the biggest jackpots in the world.

Despite their flashy lights and swank decor, most casinos are actually designed to slowly bleed patrons of their cash. The mathematically inclined (including physicists) have been trying to beat the odds by using their knowledge of game theory and probability to uncover flaws in this seemingly rigged system. While most patrons simply want to have fun, some become addicted and generate a disproportionate share of casino profits (five percent of all patrons are compulsive gamblers).

Because every game offered by a casino has a built in statistical advantage for the house, it is impossible for the casino to lose money on any one day, or even over time. This virtual assurance of gross profit allows casinos to offer big bettors extravagant inducements such as free spectacular entertainment, luxury transportation and elegant living quarters.

Because casinos handle large amounts of money, they are sometimes prone to theft and cheating by patrons or employees, either in collusion or independently. In some cases, these activities detract from the overall experience and can actually decrease a casino’s profitability. Moreover, research indicates that casinos bring in only negative economic gains to a community, because they divert spending from other forms of local entertainment and the costs of treating problem gamblers largely offset any gaming revenue.
