A casino, from the Latin for “house of games,” is a place where people can play a variety of gambling-based games. While a large part of the revenue generated by casinos is from slot machines, roulette and other table games like blackjack and craps that require some level of skill, a casino can also be a place for players to try their hand at card games or keno.

Something about casinos seems to inspire a desire in some patrons to cheat, steal or otherwise bend the rules to their advantage. That’s one reason many casinos spend a lot of time and money on security measures. In addition to requiring that patrons use casino chips instead of real money (to make it easier to keep track of what they’re losing), there are a number of routines and patterns that casinos follow when dealing cards, putting down betting spots and the expected reactions and motions of patrons, all of which can help detect irregularities.

However, the dark side of a casino isn’t limited to cheating and stealing. Studies show that compulsive gamblers can cause more harm than good to the communities in which they live, by shifting spending from other forms of local entertainment and by undermining productivity. For this reason, some states and cities prohibit casinos or restrict the types of games they offer.
