Gambling can become an addiction, so you should limit the amount of money you spend at the casino. You should bring only cash with you, leaving your bank cards at home. It is also important to set a time limit before you visit the casino, and you should consider using the pre-commitment facility if you need to.

Security in a casino begins on the floor, where casino employees monitor the games and patrons. Dealers and other employees watch for suspicious behavior and blatant cheating. Pit bosses and table managers also monitor the games to catch patterns in betting and cheating. Each employee of the casino is monitored by someone higher up.

In the 21st century, casinos focus their investments on high rollers, who spend more money than average gamblers. Many of these high rollers gamble in separate rooms from the main casino floor. Their stakes are typically in the tens of thousands of dollars. Because of the high stakes involved, these high rollers are a significant source of revenue for casinos. As a result, high rollers receive special treatment at casinos, including free comps and a luxury suite.

The main function of a casino is to accommodate various gambling games. These games can include slots, blackjack, roulette, craps, and keno. Some casinos also host live entertainment events.
