Biggest Casino Cities in the US

If you are in a metropolis like New York, Chicago, or Los Angeles, you can undoubtedly find casinos within driving distance.

Our big three casino cities are laid out for gamblers who like a selection within a walk or cab ride. They are the cities you would expect because they are known for gambling.

Las Vegas

Since the 1950s, this city of lights in the middle of the Mojave Desert has grown to become the world’s gambling Mecca and a super entertainment hub.

Las Vegas‘ famous Strip and surrounding area are home to more than 60 casinos, most of which are part of larger complexes of hotels, restaurants, and show venues.


Once the gambling capital of the US, Reno was surpassed by the rapid casino growth in Vegas in the 1960s.

But this city of nearly 250,000 still has 20 casinos, many of them hotels/casinos that offer inexpensive rates compared to Vegas.

Reno has no “Strip,” but its downtown has several casinos within a walk and more requiring just a short ride.

Atlantic City

A resort city since the early 1900s, Atlantic City became known as the “Gambling Capital of the East Coast” shortly after New Jersey legalized gambling in the 1970s.

With a population of just under 40,000, the city is home to nine resort casinos. With more law changes, AC has suffered from competition from places like Foxwoods and casinos in Philadelphia.

But it still has unique attractions such as its beach, the famed boardwalk, and saltwater taffy.
