Best Casino Games to Win Real Money in Maryland
While Maryland sweepstakes casinos might not support real-money gaming, you can still enjoy playing with Sweepstakes Coins, which you can exchange for prizes. Playing games with high RTPs like those listed below is a good idea to give you the best shot of winning SC.
Slots
How to Win Real Money on Casino Games in Maryland
RTP indicates how much a slot will likely pay back over time. For example, if the RTP is 96% and you spend $100, the slot will likely pay back $96 over time. Of course, fair games are random on every spin so that you could win more or less than this amount. It’s just an average estimated by millions of simulated spins.
For example, a game with a 98% RTP will pay out $0.98 for every $1 wagered. Games with high RTPs payout more on average in the long run. However, all games run on Random Number Generators (RNG), so each return may vary. Most online slots range from 92% % to 99% RTP, while table games typically start at around 98%.
Maryland Online Gambling Overview
Maryland Gambling Law
Maryland mirrors other states in terms of its established gambling laws. Legal online gambling options include sports betting, lotteries, and Daily Fantasy Sports (DFS). However, real-money online casino gaming in all its forms remains illegal.
The recent introduction of House Bill 17, which would legalize online casinos in Maryland, could change the entire landscape if approved. House Bill 17 is currently going through the standard governmental process in Maryland. It would grant all existing physical casinos and partners a license to launch a real-money online casino in the state.
How to Play With Maryland Casinos
Before signing up with any Maryland online casino, you should assess the safety of the respective site. We advise sticking with sites already vetted by experts - such as those we've recommended above. If you venture away from such platforms, look at the site owner/operator and search for reviews from current and previous customers for safety verification.
Once you're comfortable that a site is safe and secure, you can then successfully register by following these standard steps:
- Visit the homepage and click the sign-up/register link.
- Provide required details such as name, address, email, etc.
- Choose a username and password and add any additional security information.
- Create your username and password.
- Agree to the terms and conditions and choose your welcome offer (if available).
- Sign in and redeem your welcome bonus to play top games.
Accepted Maryland Online Casino Banking Methods
Since we are discussing sweepstakes casinos in Maryland, we must point out that payment methods aren't used for deposits. Instead, they are used to pay for coin packages. You can make prize redemptions if you are lucky enough to rack up SC.
Standard methods you can use for both payments and withdrawals include debit/credit cards, e-wallets like Skrill and PayPal, prepaid cards, and bank transfers, as confirmed by the following table:

Who Can Play at Maryland Online Casinos?
If Maryland had real money online casinos, you'd have to be 21+ to sign up and play legally. For social casinos in Maryland, you only need to be 18+. Some sweepstakes may have rules requiring you to be older, so check before playing.
You must be an MD resident to sign up and play at sweepstakes casinos. When registering, you may need proof of your age and residency, although not all sweepstakes require this.
What Legal Requirements Must Players Meet for Maryland Casinos?
Regarding retail casinos in Maryland, you must be 21+ to enter the establishment and gamble. However, you don't have to be a Maryland resident to play the games at retail casinos. Instead, anyone passing through the state who is of legal age and isn’t on a self-exclusion list can enjoy in-person real-money casino games.
Who Regulates Online Casinos in Maryland?
Technically, there is no regulatory body for the time being. If this changes, the Maryland Lottery and Gaming Control Agency (MLGCA) would become the regulator by default. This agency already oversees retail casinos and online sports betting in MD.
The regulator’s responsibilities include issuing licenses to gambling operators, monitoring DFS competitions, regulating sports betting providers, and operating the Maryland Lottery. These responsibilities relate to ensuring a safe and fair environment for all Maryland-based gamblers.
What to avoid
It’s important to understand that not all casinos you can play online are safe. There are many unsafe casinos that don’t have the same player protections from the ones we recommend.

History of Online Gambling Laws In Maryland
Maryland has had favorable laws towards gambling that date back to the 1700s. Back then, the main activities involved lottery play and horse racing, yet regulation wasn't well-established. However, from the 1920s onwards, regulation became far more formalized, and the overall gambling landscape started to take shape. Here are some key landmarks:

Legal vs Offshore Casinos in Maryland: What’s the Difference?
There is a key difference between legal casinos operating within Maryland and those classified as offshore casinos. Maryland sweepstakes casinos are sites that accept players in MD and allow them to play casino games safely for fun.
In contrast, offshore sites don't have licensing and operate illegally in Maryland, providing real-money gaming. If anything goes wrong, you have no protection from US regulators, so there is no guarantee that those sites will process your payments fairly or offer unbiased games.
What are the Best Land-Based Casinos in Maryland?
Land-based casinos in Maryland first emerged in 2010. The first to launch was the Hollywood Casino Perryville, while the most recent casino was the MGM National Harbor, which launched in 2016. Maryland has six land-based casinos, each serving a blend of slots, table games, poker, and other popular gaming categories—all regulated by the Maryland Lottery and Gaming Control Agency.
Hollywood Casino Perryville
As the first land-based casino to launch in Maryland, the Hollywood Casino Perryville was a true trailblazer. It launched in 2010 and now offers over 800 slots and table games. Additionally, this casino offers live poker and off-track betting.

Horseshoe Casino Baltimore
The Horseshoe Casino Baltimore launched in August 2014. Quite amazingly, this casino has well over 2,200 games, including high-roller slots where you can wager up to $500 per spin. For true poker enthusiasts, the fact that the Horseshoe Casino Baltimore has 22 World Series of Poker rooms puts it at the top of the list for card players.
Address: 11525 Russell Street, Baltimore
Phone Number: +1 844-777-7463
Live! Casino & Hotel Maryland
It would be unfair if we didn't draw attention to the casino with the most slot games in the state. The Live! Casino & Hotel Maryland has more than 4,000 slot games available, and with 200+ table games backing this up, the diversity of its offerings is fantastic. Furthermore, when it comes to the most immersive experiences, you can't go far wrong here since this location has the largest casino floor in the state.
