A Casino is a gambling establishment that offers a wide variety of games, including blackjack, roulette, and video slots. It also features live entertainment, top-notch hotels, and spas. Many casinos specialize in certain types of games. Some of the largest casinos in the world are located in Las Vegas, while others are found in countries around the globe.

Because large amounts of money are handled within a casino, both patrons and staff may be tempted to cheat or steal, either in collusion or on their own. This is why casinos spend so much time and money on security. The most obvious way casinos protect themselves is through cameras that watch every table and window. More sophisticated systems allow a single security worker to monitor an entire casino floor from a separate room filled with banks of security monitors.

There are also some less-obvious ways that casinos keep their patrons safe. For example, windows and chiming clocks are rarely found in a casino, because they can alert players to the passage of time and the amount of money they’ve spent. Casino designers even go so far as to hide the location of clocks and windows inside their buildings, so that gamblers can’t see how long they’ve been playing.
