The following section is a detailed review of the top five offshore sportsbooks from our top 10 list above. Review the pros and cons of each and see where your personal preference guides you as you look for your top online betting site for betting on sports in Maryland:

1. BetOnline: Opinionated Lines for Top Markets

BetOnline Homepage

Our top sports betting app is Costa Rica’s BetOnline, which receives an A+ rating from our grading system. You will get opinionated lines on top markets such as football, basketball and baseball. You can use these opinionated lines in parlays, guaranteeing you betting options that you won’t get from any other online sportsbook.

There are many different leagues and sports available to bet on as well as some non-sports markets (such as entertainment and politics). The site design is solid with menus for props builder, odds booster and the live betting section is easy to use on a mobile device.

New users will enjoy the promotions offered at BetOnline, including a 50% Sports Welcome Bonus on your first deposit (up to $1,000). You can also get a 25% sports reload bonus or 35% on crypto deposits. Your first player prop wager and live bet wager are both on the house (a $25 value) and you can also recommend a prop bet to be run on the site.


  • Quality prop builder with opinionated lines
  • Bet on everything from table tennis to handball
  • Quick payouts
  • Free pro league pick ‘em contests with real cash prizes
  • Fun sports-related promotions


  • Bonuses only valid for sportsbook

2. Bovada: The Best Prop Builder in the Industry

Bovada Sportsbook Homepage

Bovada is another well-graded, well-known sportsbook operating out of Costa Rica. You can bet on a wide variety of markets that are organized in a neat A-Z menu on the home page. 

The props builder is one of the best in the industry with plenty of over/under choices for the top leagues as well as prepared specials and player-performance doubles for each game.

While Bovada lacks a native app for download, you can add the Bovada mobile site to your home screen for instant access on your mobile device. The site is also good for live betting on various sports and major event betting. There are also a number of generous bonuses that are available.


  • Site design is simplistic but easy to use for betting
  • Superb props builder
  • Caters to crypto users
  • A must-have for poker players


  • Not that many promotions for existing users
  • Smaller bonuses if you don’t use crypto
  • They don’t post the earliest betting lines in the industry like Bookmaker

3. BookMaker: Open To Sharps & New Players Alike

If you are serious about sports betting, then the BookMaker mobile sportsbook is hard to pass up. This Costa Rica-based sportsbook has been online for over 25 years and has earned a reputation for getting the earliest betting lines out. Sharp bettors can hammer those lines before the public starts skewing things in another direction.

With high betting limits and the ability to request up to five payouts per week, you can get a lot done as a sports bettor with Bookmaker as your primary online sportsbook. They also provide a good racebook and some casino games to play for a change of pace, including video poker. 

If you join BookMaker’s excellent loyalty program, then you can eventually get 20% cash on your reload bonuses (up to $2,500). The initial welcome bonus is worth as much as $500 in bonus money with a 10x rollover.


  • Sharps eat up the early betting lines on sports
  • High limits
  • Request up to five payouts per week
  • Good live betting on mobile site
  • Loyalty program offers generous reload bonuses


  • They do sides/totals better than they do prop bets
  • No poker tournaments available

4. Heritage Sports: Reduced Juice & Live Betting 

Heritage Sports homepage

Is Costa Rica big enough for four great online sportsbooks? You bet they are. Heritage Sports is another great mobile sportsbook option that has been around since 2001. Formerly an invite-only service, anyone can join today, including Maryland users. 

The reduced juice cash-back program is something the site loves to promote and for good reason. Many sites will offer one or the other, but you will get reduced juice betting lines (-108 lines instead of the standard -110) and cash back every quarter on your sports bets at Heritage Sports.

You also get some of the best live betting choices in the industry with one of the nicest-looking sites. They also do a good job with their racebook, offer demo versions of every casino game and give esports their own hub as well, if that’s your thing.

You won’t get the biggest promotions with Heritage Sports, but their cash-back program is top-notch and you can get unique perks like a free parlay on your birthday (up to a $500 value) or getting every eighth deposit free on the house.


  • Reduced juice cash-back program is great for sports and casino
  • One of the best for live betting
  • Free parlay on your birthday adds a nice personal touch


  • One of the smallest welcome bonuses 
  • Lack the poker tournaments found at Bovada and BetOnline

 5. BetUS: Helps You Become a Better Bettor 

BetUS homepage

Since 1994, BetUS has been taking sports bets, giving it the confidence to claim itself as “America’s Favorite Sportsbook.” It is definitely top-five material for our grading system.

BetUS checks a lot of the boxes by offering a deep selection of sports betting markets, including prop picks and live betting. They also have one of the better racebooks on our list and their casino is one of the best we have seen.

With BetUS TV, the company really offers something none of the rivals do at this point. They have experts who provide analysis and picks on shows (via YouTube) for many different types of sports. This provides a more complete betting experience if you want to make BetUS your one-stop shop for sports betting each week. Other sites should follow their lead with this TV service. 

The sign-up bonuses at BetUS are unique. You can get a 200% match of your first deposit if you use crypto. It is split into two parts: 150% on sports (up to $3,750) and 50% for the casino (up to $1,250). That is a total of $5,000 in bonus money if you deposit the maximum amount ($2,500) using crypto. The sports bonus has a 15x rollover and the casino has a 30x rollover. They must be used within 14 days of receiving the promotion.


  • Welcome bonuses are large and get you started on the sportsbook and casino
  • BetUS TV provides expert analysis that you won’t get from rivals
  • Useful guides
  • Good online casino offerings with demos of everything


  • Desktop version performs better than the mobile site
  • Be aware that welcome bonuses expire after 14 days

How We Rank the Best Maryland Betting Apps & Mobile Sites

At Bookmakers Review we research each offshore sportsbook and grade it against a series of important metrics that we think a quality site should possess. We want to share some of those metrics so that you know what to look for when choosing the right online betting site in Maryland.

Mobile Betting Experience

With so many bets placed on a phone now, it is very important for a great site design that makes it easy to enjoy mobile betting; live or pre-game. We also want to be able to add money to our account on the fly, build parlays with ease and enjoy a site that won’t crash during high-traffic times like right before the start of the next playoff game.

Live Mobile Betting & Streaming

Live betting continues to get more popular and is one of the best ways to use your handheld device to place bets while actively watching a game. Most of our top 10 sites offer deep live betting markets so, no matter which hour of the day it is, you can likely find some action going on somewhere in the world.

Banking Options

Our top sites do a great job of giving you different banking methods ranging from old-school methods (checks, credit cards, money orders, wire transfers) to more modern options (P2P, eWallets, cryptocurrency options). There are also fees and different waiting times associated with your preferred payment method. These are available on each site and you should familiarize yourself with the differences when selecting what method is best for you. Sites that provide a detailed crypto guide for those wishing to learn how to use it get a higher grade as well.

Customer Service

The best customer service sites will offer 24/7 support in a variety of contact methods from email to phone calls to video chat. But 24/7 support with quick response time is the ideal goal.

Licensing & Security

You should feel confident that the site you are using is safe, that it will keep your personal information secure and that it is a legitimate company that is licensed to operate in its country of origin. The sites we have chosen for our top 10 all passed this test with flying colors.

Maryland’s Sports Betting Timeline

Maryland’s relationship with sports betting has been a remarkable tale of legislative shifts and economic growth.

This timeline traces the key milestones in Maryland’s sports betting history, starting with legislative efforts and culminating in significant economic achievements and expansions in the industry:

Types of Maryland Mobile Betting Bonus Codes & Promo Offers

There are always bonuses and promo codes associated with these sites to keep you going back for more. It is important to understand how they work and what’s really a deal to you. The following are different examples of the types of promotions and perks you will see on these offshore sportsbooks.

Welcome Bonuses & Deposit Bonuses

The most popular promotion that you will often see advertised for an online sportsbook is the welcome bonus. This is usually in the form of matching your first deposit, sometimes up to $1,000 or more depending on the site or online sports betting app and can be claimed during the registration process.

Sometimes your second and third deposits also get matched if the promotion allows for it. Crypto users usually can get a little more on their first-deposit bonuses if they use that method to make their transactions.

But with any welcome bonus, you should read the fine print about what the rollover requirement is. That number is going to tell you how many times you will have to wager that bonus money until it is cleared to be withdrawn from your account as real money. That number can get very high for casino bonuses, but the sports rollover requirements are usually among the lowest.

Returning Customer Promotions

It is always nice to see your loyalty rewarded. Some sportsbooks will offer you more lucrative promotions based on your betting level with the site. The more you bet, the more likely those rewards are going to be a larger number.

But there is a variety of returning customer promotions you can expect to see:

  • Enhanced/Boosted Odds: These are common for sports bets. You may see a line that is usually -110 get boosted to +150 for that day as part of a promotion. You just have to opt-in and claim the promotion to get the odds. There is usually a strict limit associated with these boosts and they are one-time bets that cannot be combined into parlays. Some feel that you should always fade the books when they offer these boosts, but there are plenty of times when they do in fact hit and anyone who played them got a nice boost in profit.
  • Reload Bonuses: These are basically just deposit matches for people who have a history of depositing money on a site. Put in $100 and expect them to match 50% or so. If you were going to make a deposit anyway that day, it is basically getting free money. These are offered often.
  • Risk-free Bets & Bonus Bets: These promotional wagers are always fun to see available. If you make a bet of a certain amount and it loses, you can get your stake back as a free bet. Just be aware those free bets earned through these promotional wagers usually expire within a week.
  • Free Bets: These can come as the reward to a risk-free bet or as part of a promotion for the first time you place a certain bet, such as your first live bet, first parlay or first horse race bet.

Online sports betting sites frequently offer these types of ongoing promotions to existing customers.

Mobile Site vs. App for Betting in Maryland

As Maryland residents will soon see when they can download apps for sportsbooks from major US companies, it is often easier to log in to a native app for mobile sports betting. However, the online betting sites in our list currently lack a native app that can be downloaded at the Apple Store or Play Store for iPhone and Android users.

But you can always check out the mobile site on your favorite device, which can then be bookmarked or saved to your home screen for quick, future access. We looked at some of the pros and cons of the methods of engaging in mobile sports betting on a mobile site compared to a mobile app.

Mobile Site

Every offshore sportsbook in our list has a solid mobile site that you can access to place bets. Just visit the site and log in.


  • Not taking up storage space on your phone with a growing cache the more you use it
  • Not using your monthly data allotment on your phone
  • No need to worry about downloading app updates or removing old versions of app to install new ones


  • Higher security risks
  • May have to type in password more often

Mobile App

Using a native app is going to be like using the website, but you will notice some differences.


  • One-click access to enter the app
  • Use your phone’s high-tech login method (fingerprint or code) for quick access to your account
  • Use the stored password on your phone so you don’t have to remember it or write it down somewhere
  • You can quickly share photos of your bets with friends or social media following
  • These usually have better aesthetics than the regular mobile site


  • Easier to multi-task (research stats) while betting on a PC or larger screen than on your phone
  • Must always be on the lookout for app updates, which take up storage
  • Geolocation on a phone can be very hit or miss
  • App can lag more than the site based on strength of your Wi-Fi connection

Best Maryland Betting App & Mobile Site: Conclusion

If you are wondering what our personal choice is for the best online sportsbook apps for legal sports betting, the truth is we use all the ones in our top five for different reasons. But if we were to only choose one, it would be BetOnline.

The payments are the fastest, the site design works no matter if you are building a parlay or playing casino games, the variety in sports markets is great, live betting is easy to do, the promos are varied and unique and the contests are fun to play.
