What Is a Casino?

A casino is a place where people gamble and play games of chance. They can be large, luxurious resorts or small card rooms. The casino industry brings in billions of dollars each year for the companies, investors and Native American tribes that own and operate them. State and local governments also reap revenue from taxes on gambling.

There is something about the glitz and glamour of casinos that attracts criminal elements. Something about the fact that so much money is changing hands, sometimes in ways that seem impossible or illegal. Casinos spend a lot of time and money on security. Security begins on the floor, where employees keep an eye on the patrons to make sure they are following rules and not stealing. Dealers focus on their own games and can spot blatant cheating, but table managers and pit bosses have a broader view and look for betting patterns that could indicate tampering or collusion.

Casinos use chips instead of cash to make it harder for patrons to track how much they are losing. They also give away food and drinks to keep gamblers on the premises, even though that doesn’t reduce the house edge. They may also put ATM machines in strategic locations.

A casino isn’t just a gambling hall; it’s often a destination for entertainment. It is not uncommon for celebrities to appear in shows at casinos, and famous gambling spots have become a backdrop for movies and TV. The Bellagio in Las Vegas is probably the best-known casino, but there are plenty of others around the world.
