Casinos have special rooms for high rollers, who typically spend a lot of money. These gamblers are usually separated from the average casino floor, and they have stakes that can reach tens of thousands of dollars. These high rollers are very profitable for casinos. The casino owners will usually offer them comps worth a lot of money, free luxury suites, and lavish personal attention.

Casinos use security cameras, which can help prevent petty theft. Security measures at casinos are often high, as gambling is a risky activity. The Nevada Gaming Control Board divides the Clark County area into seven market regions. In addition, Native American gaming has led to the growth of casinos outside of Las Vegas.

Casinos have elaborate surveillance systems that enable security staff to monitor the casino’s entire floor at once. These cameras are installed in windows, doorways, and tables, and they can be adjusted to focus on any suspicious patron. In addition, video feeds are recorded for later review. Casinos also use computer chips to determine the payouts on slot machines.

Casinos are licensed and regulated in every state where gambling is legal. Each state’s regulators issue licenses to casinos to ensure that casinos are safe and fair. The casinos also pay federal taxes on the money won in the gambling activity.
