A casino is a gambling establishment offering customers a range of games of chance, with some requiring skill. Most casino games have a mathematically determined house advantage over the players that is uniformly negative (except in games such as poker where the player skill can eliminate it).

The Bellagio is known for its dancing fountains, and was even featured in the movie Ocean’s 11. But this luxury hotel and casino offers much more than just entertainment and gambling. Its rooms and suites are lavish and elegant, and it also houses restaurants and other amenities.

In the United States, the most famous casinos are located in Las Vegas. However, they are now popping up all over the country as more and more states legalize them. The casino industry has a significant impact on the local economy, and it provides an important source of employment.

Most modern casinos are staffed by both physical security forces and a specialized surveillance department. These personnel often have close relationships with each other and share information about possible criminal activities or observable deviations from the expected outcomes of various casino games. For example, betting chips have built-in microcircuitry that allows them to be monitored minute-by-minute and alerts surveillance personnel to any changes; roulette wheels are electronically scanned regularly to discover any statistical deviations from the expected results.

Slot machines and video poker are the economic mainstay of many American casinos, with income derived from high-volume, rapid play at sums ranging from five cents to a dollar. In many American casinos, these revenues offset the house edge of table games and other fixed costs.
