Most casinos offer different types of comps. Large spenders can get better rewards, while smaller spenders can get lesser ones. Depending on the casino, these comps can include free slot play, discounted meals, drinks, or even tickets to a show. These programs are also valuable marketing tools for the casinos, as they help them build a database of patrons. These databases can help the casinos track trends and target advertising campaigns. In addition, many casinos will offer free slot play for loyal customers.
Security measures at a casino include elaborate surveillance systems. Video feeds are recorded for future analysis, and casino employees are able to keep tabs on each slot machine and table to avoid suspicious activity. The payouts for these games are determined by computer chips inside each machine. Because of these sophisticated systems, casino employees can prevent any suspicious activity without ever seeing anyone in person. However, casinos must also deal with other security threats. The first step is securing the casino against crime.
High rollers can also be a source of additional revenue for casinos. High rollers spend more money than average gamblers and often play in special rooms separate from the main casino floor. These players can often make millions of dollars by card-holing. This method is not illegal, but it does mean that players will have higher odds of winning. High rollers often get bonuses worth thousands of dollars, free luxury suites, and lavish personal attention.
