From the glittering lights of the Las Vegas strip to the illegal pai gow parlors of New York’s Chinatown, casinos are places where champagne glasses clink, locals and tourists mingle, and an incredible buzz envelopes all who enter. While musical shows, lighted fountains and shopping centers may draw in the crowds, it is games of chance that generate the billions of dollars in profits for casinos each year. Slot machines, blackjack, roulette, craps, baccarat and more are the building blocks of modern casinos, and this article will examine how they work, how to play them, how to stay safe, and the dark side of casino gambling.

The first step in understanding how casinos make their money is to understand that they are businesses, and, like any other business, they have a model in place designed to ensure profitability. This model is known as the house edge, and it is built into every game that a casino offers. The house edge ensures that the casino will, on average, make a profit.

In addition to the house edge, casinos often earn money by allowing players to earn comps – free goods and services – for their playing time. These can range from free hotel rooms to free meals, show tickets and even limo service and airline tickets for the big spenders. Casinos also generate a large amount of revenue from high stakes gamblers, who play in special rooms away from the main floor where bets can be in the tens of thousands of dollars.
