A casino is a building where a wide variety of games of chance can be played. While gambling certainly predates written history, with primitive protodice and carved six-sided dice uncovered in archaeological digs, the idea of a casino as a place where people can find several different ways to gamble under one roof didn’t develop until the 16th century when a gambling craze swept Europe and Italian aristocrats hosted private parties called ridotti [Source: Schwartz].

Most casinos offer a wide range of games from slots to blackjack and roulette. Many have stage shows and dramatic scenery designed to add a bit of pizazz. But, in the end, they’re all about the money. Casinos are businesses, and they have to make a profit to stay in business. They accomplish this with built-in advantages in their games that are designed to ensure that they, not patrons, win in the long run.

Those advantages can be very small, but they add up, and they’re enough to keep casinos in business. In addition to those built-in advantages, casinos also earn money from the “comps” they give players. Comps are free goods or services, such as hotel rooms, dinners, tickets to shows and even airline tickets if you’re a big spender at their casino. These are given to the most frequent and largest spenders because casinos want them to come back. In addition, high-quality customer service is a must for any online casino looking to build loyalty with their player base.
