Casinos are public places where people can gamble on games of chance. They are located near tourist attractions, such as casinos in Las Vegas. Some casinos have live entertainment. These venues also host corporate events, such as conventions.

Casinos offer a variety of games of chance, including roulette, poker, blackjack, and slot machines. The games are supervised by computers. Many casinos also offer free alcohol and cigarettes to patrons.

During the 1990s, casinos began to use technology to improve security. Some casinos have cameras that watch every table and doorway. Video feeds are recorded for later review.

Casinos spend large amounts on security. Security starts on the casino floor, where employees monitor patrons. It continues up to the casino’s security team, which keeps a close eye on game play.

Casinos also offer perks to encourage gamblers to spend more. Gamblers who earn high roller status receive lavish personal attention and are provided with free luxury suites. High rollers also get reduced-fare transportation to the casino.

Casinos also use gaudy wall coverings and bright floors to create an atmosphere of excitement. The color red is thought to cause people to lose track of time.

Casinos also offer a wide variety of amenities on their floors. Most include restaurants, free drinks, and other luxuries. Several casinos specialize in creating new games.

While most of the games in casinos are regulated by state laws, others are designed to simulate gambling. Games like two-up and pai-gow spread to Asian casinos in the 1990s.
