Security at a Casino is important, and there are a variety of precautions to take. Casinos use elaborate surveillance systems to monitor every square inch of the building. Cameras mounted in the ceiling monitor each table, window, and doorway, and can be positioned to focus on patrons who seem suspicious. The video feeds are recorded for review later. Casinos also use computer chips in the slot machines to determine payouts. While no one physically watches the slot floor, a security guard is always nearby.

In the United States, there are over 1,000 casinos, and the number is steadily increasing as more states seek to legalize this activity. At present, 40 states have some form of casino gambling. The proliferation of casinos outside Las Vegas and Atlantic City is mostly due to Native American gaming. Casinos can also be a focal point for larger cities that aren’t traditionally defined by their casino scene. However, the Las Vegas Valley has the largest concentration of casinos, and the Chicago region and Atlantic City rank third and fourth, respectively.

Because casinos profit from the greed of gamblers, they focus their investment on high rollers. These high rollers spend much more than average gamblers and gamble in special rooms separate from the main casino floor. High rollers’ stakes can be in the tens of thousands of dollars. The high rollers also enjoy special treatment and bonuses – including comps and luxury suites. In addition, high rollers receive personalized attention. While these players might have better luck than the average gambler, the casino still makes money from their greed.
