A casino is a place where people gamble on games of chance and skill. The most common games include blackjack, craps, roulette and baccarat. Most of these games have mathematically determined odds that ensure that the house always has an advantage over players and this is known as the house edge. Despite this, there are many people who gamble in casinos and the industry is thriving. According to the American Gaming Association in 2002, 51 million Americans, or about one quarter of those over the age of 21, visited a casino.

The biggest casino in America is in Ledyard, Connecticut, and features over 4.7 million square feet of gambling space. This is bigger than the entire city of Las Vegas!

In order to keep people coming back to the casino, many casinos offer free goods and services, called comps. These can include anything from free hotel rooms to dinners and tickets to shows. The goal is to make the customer feel like they got their money’s worth and to encourage them to spend more.

In order to make the most money, casinos focus on high-stakes gamblers. These gamblers often gamble in special areas separate from the main floor and their bets can be worth tens of thousands of dollars. In return, these gamblers are given free hotel rooms, dinners, limo service and even airline tickets! This strategy helps the casino make a lot of money and is one reason why casinos have such elaborate hotels, fountains, towers and replicas of famous landmarks.
