Best Real Money Maryland Online Casinos 2023

Maryland is home to six brick-and-mortar casinos that offer slot machines and gaming tables, as well as retail sports betting. For the gambler who just wants to play casino games on their favorite mobile device without leaving the house, they are clearly not the best choice.

While the Old Line State legalized online sportsbooks in 2021, the same cannot be said for playing online casino games such as poker, slots, table games, keno, and more.

Until the day comes when that is given its own legislation, your best choice is to join an offshore sportsbook with all the casino games you love.

Which one should you join? Are online casino sites safe to use in Maryland? Can you win real money? We answer these questions and more in this guide to the best online casinos for Maryland users.

Best Online Casinos in Maryland Reviewed

You have seen the top 10 list, now read on to see detailed reviews of our top five choices and the rating criteria we’ve used, which lead to their high placement on our list. Our top five online casinos are all based in Costa Rica, a country where online gambling has been legal for years.

Online sportsbooks and casino sites operating offshore are not bound to the same laws as sites that operate in the United States; they only need to follow the gambling laws where they are located. This is why you should feel free to join these online betting sites today if you want to play online casino games in Maryland without waiting years for legislation to pass.

1. Bovada: Top Choice for Huge Welcome Bonus

Bovada Casino

Bovada grades out as an A+ online casino located in Costa Rica. It is well known by American users as it runs on the top network for online poker players in the country. But besides doing poker and sports betting at a high level, Bovada also boasts an impressive online casino with more than 130 slot games and seven types of blackjack.

Bovada is also well respected as the online casino of choice for crypto users. Part of that may be thanks to the welcome bonus that can offer you up to $3,750 in bonus funds if you use crypto to make your first three deposits. 

This is an impressive all-around site for Maryland users no matter if your interests lie in video slots, poker, horse racing, or sports betting.

Pros:

  • Huge casino welcome bonus (up to $3,750)
  • Most popular casino among crypto users
  • Good selection of blackjack games
  • Best for virtual racing with live streaming of races
  • Best for poker tournaments

Cons:

  • Site looks bland compared to rivals
  • Checks are too slow to arrive
  • Not as many casino games as other sites

2. BetOnline: Top Choice for Fast Payouts

BetOnline Casino

BetOnline is another impressive A+ online casino from Costa Rica. No matter which section you use, you will be treated to a quality experience.

The poker tournaments are only rivaled by Bovada, and you can even suggest your own poker tournament ideas to show up on the site.

The sportsbook is one of the best for prop picks and parlay building, and you’ll get access to opinionated lines that no other book has for the most popular markets. The racebook has the highest daily rebate (9% on exotic wagers) out there, and the esports section is right up there with Heritage Sports for the best. 

The BetOnline casino is also loaded with hundreds of games, and many of them are exclusive to the site. You’ll find table games, slots, video poker, cash races, keno, live dealer games, and more.

Pros: 

  • Same-day crypto payouts
  • Some of the highest limits and welcome bonuses
  • Longstanding reputation in industry
  • Hundreds of casino games, including many exclusive ones
  • Unique sports lines
  • Contests offer huge prizes

Cons: 

  • Certain games (roulette/craps) won’t satisfy rollover requirements
  • Bovada still has the edge in sports props and poker tournaments
  • Casino games lack demo versions to try for free

3. Heritage Sports: Top Choice for Live Betting

Heritage Sports Casino

We think Costa Rica has the most impressive group of online casinos and Heritage Sports is another receiving an A+ grade from us. This site used to require an invite for users to join, but those days are over. Anyone in Maryland or North America is free to join today.

Once inside, you’ll find one of the best site designs and a go-to mobile site for placing live bets on a variety of global sports markets. The e-sports section is also one of the best on our list.

The casino is not as loaded as BetOnline, but they do offer free demo versions of every game available, which is a nice touch. The 3D slots and scratchcard games are types of specialty games that not every online casino offers, but they have them at Heritage Sports.

The bonuses are not as big as the competitors, but you can get 8% cash back on your net casino losses on the first of every month. This comes with a reasonable 4x rollover, and the maximum bonus is capped at $2,000.

Pros: 

  • 8% cash back on casino net losses
  • Live betting is king here
  • Try their casino games for free
  • Get boosts on e-sports parlays
  • Unique perks like free birthday parlay or every eighth deposit for free

Cons:

  • Welcome bonus is small compared to rivals
  • Smaller limits than most competitors 

 4. Bookmaker: Top Choice for Early Lines

Bookmaker.eu Casino

Bookmaker is a Costa Rica-based sportsbook that has been online since 1996. Their reputation is well earned as being the sportsbook where the line originates. Those early sports lines are the main reason to join Bookmaker, but they do offer an online casino as well.

While there are only 64 casino games on Bookmaker, they have an exclusive fast blackjack game that is fun to play. They also provide RTP (return-to-player rate) and volatility info on each game, which is very useful to know if you want to find games that are paying back the most money on a consistent basis. The other casinos in our list hide this info, but ideally, you want to see a RTP rate as close to 100% as possible. 

There may barely be 30 slots, but they are at least unique ones that most of the other sites do not have. There are also video poker games, table games, and keno.

Pros:

  • Exclusive fast blackjack game
  • Good for crypto users
  • RTP info on each casino game
  • Great sports betting available 

Cons:

  • You will only find video poker games
  • Rivals do the casino better

5. BetUS: Top Choice for Expert Analysis

BetUS homepage

BetUS advertises as “America’s Favorite Sportsbook.” It may be for some as it is a good one, but the casino is also worth checking out, especially if you want to play newer games based on popular media franchises such as Dragon Ball or Squid Game.

A great thing about the casino is that every game can be played for free using a fake money balance. This is good because you can practice on a game and see what you’d win if you wagered a certain amount each spin and if the bonuses or special features in the game might be worth trying to play with real money for. Not every site has free demo versions, but BetUS does for its many unique games.

There are also various tournaments you can enter at the casino, including ones for blackjack, roulette, video poker, and three-card poker. They lack the traditional poker tournaments found at Bovada or BetOnline, but this is better than the selection at other sites like Bookmaker and Heritage Sports.

The other way BetUS differentiates itself is by offering original content on BetUS TV, a YouTube channel with expert analysis and picks.

Pros:

  • Practice on casino games with play-for-fun demo versions
  • Original video content with expert analysis and picks on BetUS TV
  • Informative guides to help you get better at gambling 
  • Great for finding newer casino games
  • Does blackjack very well

Cons:

  • High rollover requirements for bonuses
  • Other sites have more casino games

No, even though other gambling activities are legal statewide, there is no law in place to allow online casino games such as poker, video slots, table games, and more.

But with the way gambling is moving forward in the state of Maryland, it is reasonable to believe there will be a push soon to legalize online casino games as well, especially once the revenue starts rolling in from now-legal sports betting online to fund the state’s education programs.

Until that changes, you can play a wide selection of games at sites like BetOnline, BetUS, Bookmaker, Heritage Sports, and Bovada.

How old do I need to be to play at Maryland casinos?

The legal gambling age in Maryland is 18 years old. At that age, you can visit retail sportsbooks to place a bet on your favorite team or play the state lottery.

In order to visit any of the land-based casinos in the state, you need to be 21 years old. This is because all of the land-based casinos serve alcohol and it is a common practice across the country.

In order to gamble on online games at online gambling sites, the minimum gambling age is 18 years old, or whatever the minimum gambling age is in your state.

How many retail casinos in Maryland are there?

Maryland is home to six land casinos you can visit:

• Horseshoe Casino Baltimore (Baltimore, MD)

• Hollywood Casino Perryville (Perryville, MD)

• Rocky Gap Casino Resort (Flintstone, MD)

• Live! Casino & Hotel (Hanover, MD)

• Ocean Downs (Berlin, MD)

• MGM National Harbor (Oxon Hill, MD)

You can expect to find slots, table games, and retail sportsbooks for placing wagers at each location. Some also have a live poker room with daily cash games and tournaments. Check the website for each to find the schedule of poker games available.

Types of Online Casino Bonuses – Promo Codes & Bonus Codes

Chances are you will find yourself joining multiple online casinos from our list. That is fine, if not recommended, but one of the most popular reasons for you to choose a site will be the promotions it offers. Anyone can boast a good welcome bonus, but it is the other promotions that come later that should keep you coming back in theory.

This next section looks at the different types of bonuses you should count on your favorite online casino sites to have on offer.

Welcome Bonuses

The largest bonus you will likely ever see during your time online casino gambling is the welcome bonus, also known as a sign-up bonus.

These will often be deposit bonuses, or deposit match bonuses, where the site will match 100% (or higher) of your first deposit amount. This can get into thousands of dollars depending on the site and if you use crypto or not. If it’s a casino bonus, it may also come with 10-to-250 free spins on a selection of slots.

These are great bonuses, but you will want to closely read the terms and conditions. Deposit bonuses will have rollover requirements, which is how many times you need to wager the bonus amount before it converts to money you can withdraw.

You also may need to complete a rollover on your first bonus before unlocking further bonuses. For example, the welcome bonus at Bovada’s casino boasts $3,750 in bonus money if you use crypto.

But you first have to deposit enough to get up to $1,250 on your first deposit, and that comes with a 25x rollover requirement. Then on your second and third deposits, you can get another $1,250 bonus on each, but that will come with a 50x rollover requirement.

Another thing to look out for is what games the bonus funds are not eligible to use for, or which games they will not qualify for the rollover requirement. Games like craps or live dealer gaming options could fall into this, so be careful about how you use the bonus funds.

Existing Customer Promotions

These online casinos can offer a wide variety of promotions beyond the welcome bonus. Here is a list of some of the other ways that offshore sites offer free money online for users at their casino, sportsbook, poker room, racebook, esports hub, and more.

  • Reload bonuses (usually in the 20-35% range) for deposits every week 
  • Cash-back refunds on bad beats in poker or sports like when your team blows a huge lead or gets shutout
  • Free bets at the sportsbook, especially for first-time wagers on certain markets
  • Enhanced/boosted odds on select sports markets
  • Free spins on select casino games
  • Double reward points if you play during designated “happy hours”
  • Reduced juice sports lines (-108 or -105 instead of -110)
  • Weekly casino rebates on your losses
  • Parlay boosts on e-sports wagers
  • Daily rebates on horse races
  • Get your every eighth or ninth deposit on the house
  • Free birthday parlay worth up to $500 (Heritage Sports has this one)
  • Contests to enter (for free or a fee) to win big prizes or trips
  • Refer-a-friend program where you can earn for each friend you refer
  • VIP/Loyalty/Reward programs with great perks for valued players

Payment Methods Available at Maryland Online Casinos

Arguably, nothing is more important than the ability to deposit money and withdraw your winnings from these online casinos. But when it comes to financial transactions, there are several things you will want to familiarize yourself with at your chosen site in regards to their accepted payment options:

  • Payment methods usually range from old-fashioned (credit/debit cards, checks, money orders, wire transfers, bank wire transfers, vouchers) to more new school methods (eWallets, Zelle, PayPal, P2P apps, and cryptocurrency, including Bitcoin, Bitcoin Cash and Litecoin).
  • Some sites offer a cash payment negotiation as well
  • Minimum deposit/withdrawal limits (usually $10-to-$50)
  • Maximum deposit/withdrawal limits (can be a wide range up to tens of thousands of dollars)
  • Deposit/withdrawal fees (vary by method from free to pricy)
  • Payment processing time (can be almost instantaneous to up to 15 days if waiting on a check)

Game Selection & Variety at Online Casinos in Maryland

If you have never played an online casino before, you may be surprised at just how fun it can be. The graphics look sharp, the sound effects help make you feel like you’re in a real casino, and there is a huge variety of games to choose from, including all of your favorite casino games and exotic games.

You just have to find your favorite styles of games. There are plenty of unique slot machines, including Super Slots, to spend your time with. There are video poker games, table games with many variants of roulette, blackjack, and baccarat, as well as specialty games (keno, scratchcards, and bingo). There are live dealer games where you can see a real person via video. The range of casino games available is generally much greater than what a casino player would find at retail casinos. This is one of the many benefits that online gambling sites can offer over physical casinos.

What is a rollover requirement?

All casino gamblers need to understand this. A rollover requirement must be met by wagering before you can turn your bonus funds into cash that can be withdrawn from offshore casinos.

For example, let’s say you have received $500 in bonus money with a rollover requirement of 25x. Before that $500 can be taken out, you first have to bet $12,500 on casino games (or the sportsbook if it’s a sportsbook bonus).

The highest rollover requirements, usually 20-50x, will be on the casino bonuses. The lower the rollover requirement, the better the deal is for you.

FAQs – Maryland Online Casinos

Can you use gambling apps in Maryland?

You can use any offshore mobile betting app or mobile-optimized online casino in the state of Maryland for your mobile gambling. Popular United States-based gambling apps (like DraftKings Sportsbook or FanDuel Sportsbook) can not be used for online casino gaming in the state, as online casino gambling isn’t currently legal. You can still use these apps to play Daily Fantasy Sports (DFS), however.

What online casinos pay out real cash?

You can win real money online casino gambling in Maryland with any of our top-rated online casinos. If you wager on a slot game, a round of roulette or video poker, win a sports bet or are successful with any other forms of gambling, you have won real money. The only way it is not withdrawable yet is if you are playing bonus money that you have not satisfied the rollover requirement for. That must be done first before those bonus funds are converted into real money.

What is the safest online casino for real money?

If an online sports betting site had a poor reputation, it would never crack our top-rated list or be recommended to anyone. A lot of the sites we recommended have been established since the 1990s, so they have a reputation you can count on to trust. Each of these online sportsbooks and casinos are completely safe for your online gambling activity.

Does Maryland tax gambling winnings?

Any gambling winnings or cash prizes will need to be reported to the IRS and will be taxed the same as any other source of income.

What are the six Maryland casinos?

Maryland has six commercial casinos:

• Horseshoe Casino Baltimore (Baltimore, MD)
• Hollywood Casino Perryville (Perryville, MD)
• Rocky Gap Casino Resort (Flintstone, MD)
