To keep patrons and employees safe, casinos use elaborate surveillance systems. These include cameras installed in the ceiling of the casino and in windows and doorways. They are programmed to focus on suspicious patrons, and the video feeds are recorded and analyzed afterwards. Casinos also use computer chips to determine the payout of slot machines, making it difficult for anyone to rig the game.

Casinos are fun places to socialize and play games of chance. They have elaborate themes and décor and sometimes even host live entertainment. In the United States, casino gambling generates billions of dollars for U.S. casinos every year. The most popular games played at casinos include slot machines, blackjack, roulette, and craps.

Casino chips come in many colors and represent different values. Red chips represent five dollars, green chips are worth twenty-five dollars, and black chips represent one hundred dollars. The value of casino chips varies locally and nationally. Different casinos will use different colors for different games. When players win, they can cash in their chips for cash. Casinos brand their chips to make sure that no one can counterfeit them.

Some casino games have built-in statistical advantages. The edge is very small, and can be as small as two percent. Still, casinos make enough money to build lavish hotels, giant pyramids, and towers. This edge is known as the “vig” or “rake”. However, casino payouts depend on the type of game and the player’s bankroll.
