In earlier times, casinos referred to a small villa or outhouse built on the grounds of a larger Italian villa or palazzo. These were built specifically to house entertaining activities. Since the 19th century, the meaning of the word casino changed completely. Casinos then included public buildings where leisure activities such as gambling and sports were housed.
A casino refers to a building that allows all sorts of gambling games and activities. Players may gamble by playing slot machines or board games. Whether a player plays directly with the casino or with another fellow player, the casino has a predetermined stake in all the winnings. In the latter case, the set amount is known as commission.
It is important to realize that casinos do not create wealth. Casinos by themselves cannot generate revenue. However, they are institutions where wealth is usually transferred. In the gambling business, a set amount of money is spent with the possibility of winning more money. In relation to casino income, most of it is money that has transferred from the players’ hands to the casino.
