Casinos are places where people gamble by playing games of chance. They offer a variety of games, including blackjack, poker, and roulette. However, the most popular games are usually the slot machines. These are electronic machines that randomly award payouts to the winners.
Many casinos employ specialized security departments, which work together to ensure the safety and well-being of their guests. The physical security force mainly patrols the casino floor and responds to any calls for assistance. Similarly, a specialized surveillance department watches every table and every window to catch any suspicious behavior.
A casino also offers a wide array of other recreational activities. Some venues include dance shows, concerts, and live entertainment. Others have video poker. Other games include slot machines, roulette, blackjack, and craps.
