You’d think the answer is easy. It’s Nevada, right? Everyone knows Las Vegas is the gambling capital of the world. But if you’re actually looking for the state with the most individual casino locations, the answer gets a little weird.
It depends on who you ask and how they count.
Honestly, the "most casinos" title is a bit of a moving target. In 2026, the landscape of American gaming has shifted. We aren't just talking about the neon lights of the Strip anymore. We're talking about tribal lands in the Midwest, historic gold-rush towns in the Black Hills, and card rooms tucked away in California suburbs.
The Undisputed Heavyweight: Nevada
Let’s get the obvious one out of the way. Nevada still holds the crown. It’s not even a fair fight. According to the most recent data from the American Gaming Association and state regulators, Nevada has roughly 345 casinos.
That is a massive number. To put it in perspective, that’s more than some entire countries. But here’s the kicker: not all of these are "resorts." In Nevada, a "casino" can be a massive 3,000-room hotel-casino on the Strip, or it can be a small storefront in a Reno strip mall with fifteen slot machines and a bar.
Why does Nevada have so many? Basically, it’s the law. Nevada is one of the only states where "non-restricted" gaming licenses are handed out like candy. You’ll find slots in grocery stores, gas stations, and airports. While those don't always count as "casinos" in the traditional sense, the state’s dedicated gaming halls still outnumber every other state by a mile.
The Shocking Runner-Up: Oklahoma
If you aren't from the South Central U.S., this might blow your mind. Oklahoma is the second state with the most casinos. We are talking about over 140 physical casino establishments.
Wait, what? Oklahoma?
Yes. The Sooner State has become a powerhouse because of tribal gaming. There are over 30 different Native American tribes operating gaming facilities there. Because of the way tribal compacts work, these casinos are spread out across the state rather than being clustered in one "Sin City" hub.
You’ve probably heard of WinStar World Casino. It’s located in Thackerville, right on the Texas border. Fun fact: it’s actually the largest casino in the world by floor space. It’s bigger than anything in Vegas. Most people driving up from Dallas don't realize they are entering the second-most casino-dense state in the country until they see the massive towers rising out of the plains.

Why the Rankings Get Messy
Here is where it gets kind of annoying for researchers. Different organizations define a "casino" differently.
- Commercial Casinos: These are state-licensed and taxed (like in Atlantic City or Las Vegas).
- Tribal Casinos: These operate under federal law (IGRA) and state compacts.
- Card Rooms: California has dozens of these. They look like casinos, they smell like casinos, but they can't have "house-banked" games like traditional blackjack or slots.
- Video Gaming Terminals (VGTs): States like Illinois and Pennsylvania have thousands of these in bars. If a bar has five slots, is it a casino? Most experts say no, but it feels like one when you're losing twenty bucks.
South Dakota and the "Per Capita" Trap
If you look at the raw count, South Dakota usually sits around 35 to 40 casinos. That doesn't sound like much compared to Nevada’s 345.
But look at the population. South Dakota has fewer than a million people. When you calculate casinos per 100,000 residents, South Dakota suddenly looks like the gambling capital of the universe. Most of these are packed into Deadwood, a historic town where you can walk from one "casino" to another every ten feet. Most of them are tiny—kinda like old saloons with a few machines—but they count on the official tally.
The Top Five Leaderboard (By Location Count)
Based on 2025 and 2026 industry reports, here is the rough breakdown of the states with the most physical casino buildings:
- Nevada: ~345 locations.
- Oklahoma: ~143 locations (almost all tribal).
- California: ~86 locations (a mix of massive tribal resorts and card rooms).
- Montana: ~50+ (this is a weird one—Montana has hundreds of "casinos" that are actually just taverns with a few machines, but major gaming halls are fewer).
- South Dakota / Colorado: Tied around 35-40 locations.
The California Complexity
California is a beast. If you counted every place you could legally play a card game for money, California might actually challenge Oklahoma. But California’s 60+ tribal casinos are massive. Places like Pechanga or Yaamava’ are behemoths.
However, California also has roughly 80 "card rooms." These aren't full casinos because they lack slot machines. If you’re a slots player, California might feel like it has "fewer" options than Oklahoma, even though the buildings are twice as big.
What Most People Get Wrong
People often confuse "most revenue" with "most casinos."
New Jersey (Atlantic City) only has about 9 casinos. That’s it. Just nine. Yet, they generate more money than almost any other state besides Nevada and Pennsylvania. Pennsylvania only has 17 casinos, but because they are located in high-traffic areas like Philadelphia and Pittsburgh, they are absolute gold mines.
If you want variety and "state with the most casinos," you head to Nevada or Oklahoma. If you want the biggest, highest-stakes environments with the most amenities, the count doesn't matter as much as the size of the property.
Planning Your Next Trip
If you are a "casino hopper" who likes seeing five different places in one afternoon, your best bets are:
- Las Vegas, NV: Obviously.
- Deadwood, SD: For that Wild West, small-scale feel.
- Black Hawk/Central City, CO: These two towns are right next to each other and packed with casinos.
- Tunica, MS: A bit of a throwback, but plenty of options in a small radius.
The reality is that gaming is expanding. Nebraska just started opening casinos. Virginia is building them fast. Even North Carolina and Florida are expanding their tribal footprints. The "most" title might belong to Nevada for our lifetimes, but the gap is closing as more states realize how much tax revenue they are leaving on the table.
Actionable Insights for the Savvy Player
- Check the Type: Before you drive three hours, verify if it’s a "Class II" or "Class III" casino. Class II (common in some tribal areas) uses bingo-based math for its slots, which feels slightly different than the traditional Vegas-style Class III machines.
- Join the Rewards Club: Because states like Oklahoma have so many casinos owned by the same tribes (like the Choctaw or Chickasaw), one rewards card often works at dozens of locations.
- Watch the Per Capita: If you hate crowds, avoid the "most casinos" states during holiday weekends. A state with "fewer" casinos like Ohio or Massachusetts will be much more crowded per square foot than a place like Nevada where the supply meets the demand.
By the way, if you're looking for the absolute most "bang for your buck," the density of the Las Vegas Strip still can't be beaten, regardless of what the raw state-wide numbers say.
