Best Maryland Online Casinos
Are Online Casinos Legal in Maryland?
Currently, Maryland does not regulate or license real-money online casinos, and online casino gambling is yet to be legalized in the state. While Maryland has embraced online sports betting, lawmakers are yet to legalize online casinos to operate within state lines.
There have been efforts to change this, including House Bill 17 (HB17), introduced in January 2025 by Delegate Vanessa Atterbeary, and Senate Bill 340 (SB340) by Senator Ron Watson.
These bills aimed to establish a legal framework for online casinos, allowing existing land-based operators to offer online games and proposing tax structures and consumer protections. However, neither bill advanced during the legislative session, leaving online casinos unregulated for now.
Despite the lack of state-regulated online casinos, Maryland players still have access to various offshore online casinos that accept players from the state, including the trusted sites we’ve listed in this article.
These offshore platforms provide a wide range of casino games and welcome Maryland residents while the state continues to explore legalization and regulation.
Reviews of Maryland’s Online Casinos
Let’s break down the features, games, and bonuses that make the top five Maryland online casinos worth your attention.
1. Slots of Vegas – Best Maryland Online Casino Overall
Pros:
- $2,500 bonus with 5x rollover
- Hit slot games from RealTime Gaming
- 25 extra promo codes
- Broad range of video poker games
- Around 10 deposit methods
Cons:
- Live games only visible after signup
- Could improve the website design
The best online casino in Maryland? According to our extensive research, that would be Slots of Vegas. Let’s explore why.
Casino Bonuses: 5/5
If you enter the promo code NEW250 while you make your first payment of at least $30 at Slots of Vegas, you’ll get a 250% deposit match of up to $2,500. And, there are 50 free spins included in the offer as well.
The wagering requirements for this deal are only 5x, which is way below average and should therefore save you a lot of time.
Alternatively, you can opt for the 190% deposit match of up to $1,900, which is eligible for all casino games. To activate it, use the code NEW190.
There are plenty of other promo codes to use from this point forward as well. The promotions page at Slots of Vegas is full of free spins and matched deposits for all kinds of players to grab.
Slots & Other Casino Games: 4.95/5
Slots of Vegas has over 240 MD online slots to play, and almost all of them come from RealTime Gaming. While this might not be the largest number in the US, the fact that most of them come from a trusted provider means that you’ll waste no time picking mediocre options.
The rest of the game collection consists of plenty of online poker options, as well as some roulette, specialty games, and more.
The main thing holding Slots of Vegas back from picking up the highest scores for this category is the fact that there are no live casino games available unless you create an account.
Banking & Usability: 4.9/5
There are a lot of payment methods available at the best Maryland online gambling site. These include VISA, Ethereum, and Discover, among others.
However, getting paid out quickly is only possible via Coindraw, and this will incur a fee of 5%. Other payout options if you’re not in a rush include Bitcoin, bank transfer, and check transfers.
Overall Score: 4.95/5
There’s no doubt that Slots of Vegas is the best real money online casino in Maryland. Its slots and bonuses are enough proof for us, so feel free to check them out yourself.

2. Super Slots – Best Online Casino in Maryland for Slot Games
Pros:
- More than 1,490 online slots
- Over 20 payment methods
- Rival Gaming and BetSoft slots
- 300 free spins offer
- Frequent slot tournaments
Cons:
- No way to withdraw with an eWallet
- Not so easy to search through games
Super Slots is the top MD online gambling site for slot machines. There are over 1,490 titles in total, and that figure contains some true classics.
Casino Bonuses: 4.9/5
Super Slots kicks things off with a generous 300 free spins welcome offer. Just make your first deposit, and the spins will start arriving the next day, valid for 24 hours each. It’s an easy, no-fuss way to start playing with extra chances.
Existing players can enjoy weekly promos like Midweek Super Spins (100 free spins every Thursday), Slots Smash to Cash ($50 cash prize on Fridays), and Super Slot of the Week (20 extra spins on the featured game).
Slots & Other Casino Games: 4.9/5
There’s a total of over 1,490 online slots to play at Super Slots, which is more than the majority of other Maryland online gambling sites.
The list of software providers that have contributed to the games is strong, too, so we know they’re worth a spin. BetSoft and Rival Gaming are on the list, for example, so you can expect high RTPs and super fun themes.
You’ll probably see that number rise again sometime soon. This MD online casino wastes no time in adding new slots to its repertoire.
Fun fact: Super Slots is also one of the best Texas online casinos we could find.
Banking & Usability: 4.9/5
Something that really stood out to us at Super Slots is the long list of payment methods supported in the United States. There are more than 20 here, with all kinds of cryptocurrencies and credit card types accepted, amongst others.
It’ll take around 24 hours for you to get paid out with most of these options, which is pretty quick. However, you won’t be able to cash out with eWallets.
While the basic setup of the website is strong (even for smaller smartphone screens), we would have liked to have seen some more subcategories for the games to make it easier to find your favorite titles.
Overall Score: 4.9/5
As you can see from the final scores, Super Slots and Slots of Vegas really are neck and neck for the top spot. At the end of the day, most people looking for the best Maryland casino online will be served very well at either site.

3. BetOnline – Best Online MD Casino for Live Dealer Games
Pros:
- More than 80 live casino games
- 100 free spins with no wagering
- Competitive sports odds for football and baseball
- Payouts processed in minutes
- Extra cash prizes through Daily Races
Cons:
- No bonus cash in welcome bonus

The bronze medal online casino in Maryland is BetOnline. It might be more of a sportsbook to some players, but it’s a mighty fine place to play live casino games as well.
Casino Bonuses: 4.8/5
BetOnline is offering everybody who signs up for a new account a 50% match up to $250 in bonus bets plus 100 free spins when they enter promo code FREE250 in the cashier. It’s a good deal, but it would have been nice to have seen some bonus cash available for casino games as well.
On the bright side, there’s no need to wager this offer at all. If you win anything from either the sports bet or the free spins, you can cash out those winnings right away or put them into your bankroll to play whatever you like.
Slots & Other Casino Games: 4.8/5
Currently, the total number of live dealer games at BetOnline is over 80, more than what other Maryland online casinos can offer. This site also wins with its diversity, offering blackjack, roulette, game shows, and more.
You can also play online poker here. The site has its own original poker network with high-traffic tournaments and dedicated bonuses (including a $1,000 welcome bonus using promo code POKER1000).
As we’ve already alluded to, BetOnline also offers sports betting and a racebook if you prefer horse racing, and it does its job quite well. It is actually one of the greatest online sports betting sites in California, with some of the most competitive odds and event coverage.
Banking & Usability: 5/5
Another benefit of using BetOnline in the US is the speed of the payouts. With the most cryptocurrencies supported at the site, you’re going to get your cash in under one hour. Sometimes, the process can be even faster, delivering your money within minutes.
There are plenty of payment methods that you can use for deposits and payouts here, too. The list includes over 20 methods.
All of this, combined with one of the most visually engaging and easy-to-use websites (for desktop and mobile), makes for a perfect score in this category.
Overall Score: 4.85/5
The fact that BetOnline excels with its casino games despite being a sportsbook first and foremost is truly impressive. But then again, it has had over 30 years to perfect its craft…

4. Lucky Red Casino – Best Bonuses of All Maryland Online Gambling Sites
Pros:
- 400% up to $4,000 welcome bonus
- An extra free $75 casino chip
- Over 200 high-quality games
- Offers phone support
- Daily promotions to choose from
Cons:
- No live dealer games
- Very old-school design
Having been formed in 2009, Lucky Red Casino is one of the older Maryland casinos in our rankings. But it’s still going strong, and its welcome bonus plays a huge role in that.
Casino Bonuses: 4.9/5
There’s a massive 400% deposit match of up to $4,000 waiting for all new US players at Lucky Red Casino. It also includes a free $75 casino chip for those who make their first payment using crypto. Just use the promo code LUCKYRED400.
This Maryland online casino offers players a variety of ongoing daily promotions, loyalty rewards, seasonal bonuses, and referral gifts, among others.
Slots & Other Casino Games: 4.7/5
There are just over 200 games to play at Lucky Red Casino, so not a huge figure. Most of those games come from RealTime Gaming, though, so at least you can tell the quality is going to be good. That’s particularly true of the slots, the largest part of the game collection.
Lucky Red Casino is also among the best live dealer casinos in Maryland, as it offers quite a few variants. These include Suit ‘Em Up Blackjack and 21 Blackjack.
However, you won’t actually find any live casino games. This feels like quite a large omission, and one that has prevented Lucky Red Casino from claiming a higher spot on our list of Maryland online gambling sites.
Banking & Usability: 4.7/5
The deposit methods available to Maryland bettors at Lucky Red Casino include VISA, Bitcoin, Tether, and American Express. It’s a fairly strong list.
The website does feel a little out of date, but there are a few saving graces. For example, it’s generally well laid out, and we liked that all of the games have a key showing whether they are available for instant play, download, or mobile.
It’s also worth noting that Lucky Red Casino still has telephone support for those who are more traditional with their service requirements.
Overall Score: 4.8/5
If Lucky Red Casino were to add a few online casino games to its ranks, it may well have found itself on our podium. Its welcome bonus and online slots certainly brought it close.

Maryland state has not legalized or regulated local online casinos. This means that offshore brands are not licensed by the state. However, current laws generally target the operators of illegal gambling businesses, not individual players who choose to use international websites.

Offshore casino sites are licensed outside of the United States, usually by international jurisdictions like Curaçao or Panama. These foreign licenses allow them to legally accept players from many locations, including Maryland. Plus, it ensures the sites follow basic rules for fair play and player protection, even if they’re not regulated in the US.

Regardless of where you win, any gambling winnings are considered taxable income by the IRS (federal tax) and by the state of Maryland. It’s a good idea to keep track of all winnings as you’re responsible for reporting them on your tax return.

Stronger Offers: The bonuses at Maryland real money online gambling sites are a lot better than they are at any land-based ones.
