Casinos can be found throughout the world and are a major source of revenue for local governments. They can also attract tourists from outside the area, thereby increasing the tourism market in the region.

Among the most popular casino games are slot machines, which earn casinos a large proportion of their revenue. These machines typically feature varying bands of colored shapes that roll on reels and can be played by anyone who can pull the handle or push the button.

In the United States, the largest number of casinos are located in Nevada and Atlantic City, New Jersey. However, the trend of casino gambling has spread across the country with 40 states now allowing casinos to be built in their jurisdictions.
