Generally, casinos are public places where people play games of chance. Typically, the games are designed to give the house an edge over the player. The house edge comes in the form of a rake, which is a small percentage of the pot. This is paid to the casino after each hand is played.
Casinos can be found throughout the United States and in other countries, such as Mexico and Puerto Rico. These casinos are highly profitable.

In addition, people become addicted to gambling, which can cause damage.

Casinos use security cameras and other measures to keep players safe. These cameras are mounted on the floor and ceiling, so that staff members can monitor every game. They can also adjust the cameras to focus on suspicious patrons.

Casinos also offer free drinks and other incentives to lure people in. This is called comps, and they are awarded to people who gamble and stay at the casino for a certain length of time.
