A casino is a gambling establishment that offers a variety of gambling games. These games have a random outcome and are generally played for cash or tokens (referred to as chips) that can be redeemed for winnings. In addition to the games themselves, casinos typically offer extravagant inducements such as free spectacular entertainment and luxury hotel rooms for those who bet large amounts.

There are three major categories of casino games: gaming machines, table games, and random number games. Gaming machines, like slot machines and pachinko, are operated by a machine, rather than a dealer, and do not require the involvement of casino employees. In contrast, table games such as blackjack and craps involve one or more players competing against the house, and are operated by casino employees known as croupiers. Random number games are based on the selection of random numbers generated by a computerized system or other equipment.

The modern casino industry is regulated by government and professional organizations, as well as the self-regulation of the gaming operators themselves. Security is also a key issue in the casino industry. Casinos employ two main types of security: a physical security force and a specialized surveillance department. A combination of these security measures has proven effective in reducing crime within the casino. Despite these measures, a casino’s security is only as strong as its staff and rules of conduct. A casino’s security department is responsible for enforcing these rules and monitoring the behavior of guests.
