Vegas actually doesn't even make the top seven (it can't even claim to have the largest casino in the US), with other spots like the Foxwoods Resort Casino in Connecticut and the Tisk Rio Casino Resort in South Africa all beating out anything in Nevada.įor those on the East Coast of the United States, don't fret as plenty of the casinos and resorts in Atlantic City, New Jersey, are also among the biggest casinos in the world. So where is it? Casinos like the Venetian and City of Dreams in Macao, China, also spelled Macau, actually top the list as the two biggest casinos in the world. Sin City certainly has many on this list, but the largest casino in the world is actually all the way across the world. Though it's well-known for gambling, the casinos in Las Vegas, Nevada, do not rule all others. Filled with poker rooms, table games and more slot machines than you can imagine, these casinos take the cake for being the biggest in the world and include many of the biggest names in casinos as well. Each a gambler's paradise, the biggest casinos in the world are the largest adult playgrounds that exist.
