A casino is a place where customers gamble by playing games of skill or chance. Most casino games have mathematically-determined odds that give the casino a slight advantage over its players. This edge is called the house edge or rake. Players can also receive complimentary items or comps at the casino. In addition to games, a casino can also offer free entertainment and food. However, it’s important to be aware of potential hazards.

Casinos have strict rules regarding personal electronic devices, including cell phones. Cell phones cannot be used while seated at a casino game, because the walls block cell phone reception. To use a cell phone, patrons must walk outside of the casino to get a dial tone. Also, pagers and cell phones are not allowed inside the casino’s sports book.

Casinos use elaborate surveillance systems to monitor patron behavior. Video feeds from cameras installed in the ceiling can capture suspicious behavior and alert security personnel. Security personnel can adjust the camera angle and focus it on particular patrons if necessary. Video feeds are also recorded for later review. Casinos also use computer chips in the slot machines to determine the payouts. These chips help ensure fair play and make casinos more appealing to visitors.

Casinos also feature a range of table games. Baccarat is a casino staple, but other games such as Keno and Craps are also popular. Some casinos also feature smaller niche games such as Casino War.
