How Does a Casino Make Money?

A casino is a place where people can gamble on games of chance. These games may include dice, card games such as poker and blackjack, slot machines, and video poker. Most casinos also offer other entertainment activities such as restaurants and bars.

The casino industry is a major economic contributor in many cities and towns. However, studies indicate that problem gambling erodes any economic gains. It is estimated that five percent of casino patrons are addicted to gambling and generate a disproportionate share of profits (about 25 percent). The cost of treating these compulsive gamblers often offsets any local benefits that the casino might bring.

Most casinos make money by charging players a fee to play their games. This is known as the house edge or vigorish and is usually a small percentage of the total bets made. In addition to this fee, some casinos also take a share of the winnings from certain games, which is called the rake. The amount of this is determined by the rules of the game. Casinos usually advertise the percentage of winnings for each machine on their gaming floors and in their printed materials.

Casinos also entice people to gamble by offering free goods and services, or comps, to high-volume customers. These can include drinks, meals and hotel rooms, show tickets, limo service and airline tickets. In some countries, these perks are legalized by government regulation. In others, they are illegal or regulated by state law. In either case, they are often used to attract gamblers from other areas.
