A Casino is a place where you can spend money and win money. The casino makes money by focusing their investments on high rollers who are willing to spend much more than the average person does. These people gamble in exclusive rooms, usually separated from the main casino floor, and they may stake tens of thousands of dollars. High rollers also receive lavish personal attention and comps worth thousands of dollars.

Casinos also enforce strict security procedures, which include cameras and rules of conduct. Some casinos even have catwalks in the ceiling to monitor the floor. These catwalks have one-way glass that lets surveillance personnel monitor the casino floor. But security is not the only concern at a Casino. It is not uncommon for a patron to be watched while playing a card game.

Many modern casinos have elaborate decor and offer many games of chance. They are often built close to tourist attractions. While casinos have elaborate themes and elaborate games, their major focus is on gambling. Without gambling, casinos would be nothing more than an overpriced theme park. Casinos generate billions of dollars in the U.S. every year, mostly from slot machines, blackjack, roulette, and craps. Some casinos also feature live entertainment.

Casino gambling was not legal throughout the nation until the late 1970s, and the first casinos opened in Atlantic City, New Jersey. The efforts of Native American tribes to turn bingo halls into casinos were responsible for the shift in gambling laws. By the 1990s, nine states had legalized commercial casino gambling.
