These are the most common types of Maryland sports betting promotions to look out for:

💰 Bonus Bets

Lots of Maryland betting apps and online sports betting websites will reimburse you in the form of bonus bets, if your first wager does not win. You might occasionally find that the refund is paid in cash, allowing you to immediately withdraw it. However, most of these bonuses are typically issued as bonus credits, which need to be played through before you can withdraw any winnings.

💰 Deposit Bonus

This Maryland sports betting promo matches your first deposit amount with bonus credits. For example, you might be offered a 20% deposit match, up to $1,000, or a 100% deposit match, up to $500. You then need to roll your bonus funds over before cashing out any profits.

💰 Reload Bonus Offers

A reload bonus provides online sportsbook users with a matched deposit separate from the welcome offers featured in this Maryland sportsbook promo review. These bonuses offer existing users the opportunity to reload their accounts and have their deposits matched up to a specified amount. For instance, FanDuel Sportsbook Maryland might present a 50% reload or "next deposit" match of up to $100. Opting in is required to use this offer.

💰 Odds Boosts

Many leading Maryland sportsbooks provide users with odds boosts. These boosted odds target a specific market for that day in your state or region. For instance, you might find an odds boost featuring Derrick Henry to go over 100 yards rushing. While the market's odds typically hover around -140, an odds boost could elevate it to +105, increasing the value of the wager.

💰 Referral Bonus

You can request a unique referral link and send it to a friend to claim this type of Maryland sportsbook promo. If your friend uses the link, signs up and makes a minimum deposit, you will receive a bonus bet, which is often worth $50 or $100. Your friend will normally be given an equal-sized bonus bet.

💰 Loyalty Bonus

Loyalty programs such as Caesars Rewards and MGM Rewards provide ongoing perks for repeat customers. You will earn points for placing sports wagers in Maryland, and the points can be redeemed for bonus bets and other rewards. The loyalty bonuses can also often lead to perks at corresponding land-based casinos, such as Horseshoe Baltimore for Caesars Rewards or MGM Grand Harbor for MGM Rewards.

The best Maryland sportsbook promo codes come with specific terms and conditions, making it important to read the fine print for these welcome offers. These terms tell you how to redeem the Maryland welcome bonuses and what you need to do before cashing out your winnings.

These are the main Maryland sports betting promo code terms and conditions to look out for:

Playthrough Requirements

A rollover or playthrough requirement tells you the number of times you must play through your bonus bets before the sportsbook allows you to withdraw your winnings. Most Maryland sportsbook bonus codes will have a 1x playthrough requirement.

Qualifying Bets

A qualifying bet means that you need to place a minimum bet to qualify for the Maryland sports betting bonuses. 

Minimum Deposits

Every Maryland betting promo requires a minimum deposit amount when it comes to redeeming a welcome offer. You must meet this requirement to use any Maryland sportsbook promo code. 

Minimum Odds

Certain Maryland sportsbook promo codes may set odds restrictions or require minimum odds when it comes to activating a welcome offer or using bonus bets. 

Cashing Out

While most sports betting sites in Maryland offer the option to cash out bets, this feature typically does not apply to bets made with welcome offers or bonus bets. If you choose to cash out a bet made while redeeming a welcome offer, that specific wager will be disqualified from participation, meaning you will not get your bonus. 

Expiry Dates

Each Maryland sports betting promo, including any bonus bets earned, is subject to expiration dates. If you do not use the bonus within that time, the sportsbook will withdraw any remaining bonus bets from your account.

🏈 Baltimore Ravens

All of the best Maryland sportsbooks feature NFL betting promos. Many of these bonuses and promos are not only sport-specific, but they may be team or state-specific as well. For example, you can bet on an odds boost that bolsters Lamar Jackson's touchdown pass prop to go over 1.5. Normal odds may be -130, but those boosted odds may be set at +100.

With Lamar Jackson being one of the top quarterbacks these days, NFL MVP odds should be a first stop for new Maryland bettors everywhere.

🏈 Washington Commanders

You can bet on many different NFL markets with sportsbook promo codes, these include futures, player props, moneylines and year-round Super Bowl odds. For example, you can bet on Rookie of the Year or the Washington Commanders win total odds. 

⚾️ Baltimore Orioles

The Baltimore Orioles feature a roster of rising stars. Since they are becoming one of the most popular teams in baseball, Maryland bettors will find numerous best MLB betting promos centered around them. For example, you may find a bet-and-get bonus featuring an Orioles' game in primetime. 

⚾️ Washington Nationals

You can bet on any team's World Series odds throughout the Major League Baseball season, and even ahead of it. This includes the Washington Nationals. If you think this is the year the Nationals can make a run (you never know), you can bet on one of their futures with bonus bets collected from your favorite MLB betting sites. 

🏀 Washington Wizards

The Washington Wizards may not be a powerhouse in the NBA, but that does not mean you have to miss out on the top NBA betting promos. Most sportsbooks offer NBA same-game parlay boosts that you can use to bet on Wizards player props, like any player's PRA (total points, rebounds and assists) line. 

🏒 Washington Capitols

Using NHL betting promos is a great way to gain bonus bets while wagering on Washington Capitols betting markets. 

🏆 Maryland Terrapins

You can bet on college sports in Maryland with the best college football betting promos and college basketball betting promos. Maryland is the home to a handful of popular college sports programs like Towson and Loyola, but the Maryland Terrapins are the cream of the crop. You will find Terps props when you want to bet on March Madness odds and CFB National Championship odds.
