Casino is an establishment where gambling activities take place. Casinos often include a hotel, restaurant, retail shops, and entertainment venues. The casino industry generates billions of dollars in revenue each year. Casino games like slots, blackjack, roulette, poker and other table games provide the bulk of this money. Other attractions like musical shows, lighted fountains, shopping centers and elaborate themes help draw in the crowds.

While gamblers may be lured by the bright lights and sounds, casinos use a number of tricks to get them to keep coming back for more. For example, slot machines are designed to appeal to the senses of sight and sound with flashing lights, bells and whistles. They also dispense coins with a specific rhythm to encourage patrons to continue playing and build up their winnings. Many Asian casinos offer traditional Far Eastern games such as sic bo, fan-tan and pai gow.

Casinos also employ a number of high-tech security measures to prevent cheating and other illegal activity. Surveillance cameras are placed in the ceilings to monitor every table, window and doorway. Some casinos even have a “catwalk in the sky,” which allows surveillance workers to look directly down through one-way glass at the tables and slot machines below. Elaborate computerized systems track the exact amount of money wagered on each game minute-by-minute and warn them of any suspicious behavior. Similarly, roulette wheels are monitored electronically to find out quickly if there is any statistical deviation from their expected results.
