FanDuel Sportsbook MD Bonus

Bonus: Bet $5, Get $200 in Bonus Bets If Your Bet Wins

Use promo code: Click to claim promo

FanDuel is another fantastic online sportsbook with lots to offer starting with its welcome bonus new sign-ups. Unlike its competitors, FanDuel doesn’t require a promo code to activate the bonus. Instead, all users need to do is click “play now” and sign up.

By the way, when you receive FanDuel bonus bets, one great advantage for players is that the bonus bets can be divided up however you choose. For example, a $100 bonus bet at most other Maryland sportsbooks would have to be used in its entirety on a single wager. But with FanDuel’s bonus bets, users can spread the amount across multiple bets, at varying stakes, until the sum runs out.

Caesars Sportsbook MD Promo Code

Bonus: Bet $1, Double Your Winnings on Your Next 10 Wagers

Use promo code: PLAYMDDYW

Caesars is one of the most recognizable names in sports betting and has strong ties to Maryland. As an official sports betting partner of the Baltimore Ravens and operator of a retail sportsbook at the Horseshoe Casino Baltimore, Caesars is a brand you can trust.

As a welcome bonus, Caesars will give you profit boosts to double your winnings on your next 10 wagers after your first bet of $1 or more. Use code PLAYMDDYW during sign-up to claim the offer.

Boasting a diverse wagering catalog and daily odds boosts, which sometimes exceed 40 offers per day, there’s never a shortage of wagering options with Caesars Sportsbook.

Fanatics Sportsbook MD Bonus

Bonus: Up to $1,ooo in No Sweat Bets

Use Promo Code: Click to claim

Fanatics Sportsbooks comes from humble beginnings as a sports merch company, which quickly grew to become an empire. Then, with the company’s acquisition of PointsBet US, it became a heavy hitter in the sports betting space.

Now, Fanatics is among Maryalnd’s top sportsbooks with a top-tier mobile experience. It’s especially great for sports fans who want team merch; you can earn Fancash as you play and redeem it for merch items or other prizes.

BetMGM Sportsbook MD Bonus Code

Bonus: Up to $1,500 in Bonus Bets If Your First Bet Doesn’t Win

Use promo code: PLAYMD

BetMGM became the first official gaming partner of the Baltimore Ravens in May 2021; a move reflected in the special offerings for Ravens fans on the BetMGM app. The operator also runs a 125,000 square-foot retail sportsbook through its MGM National Harbor property, the largest and most successful Maryland casino.

In short, you can trust the self-proclaimed “king of sportsbooks.”

So, what can players expect from BetMGM’s welcome bonus? When signing up, enter the bonus code PLAYMD place your first bet. You’ll get up to $1,500 in Bonus Bets back if you don’t win.

Part of BetMGM’s appeal is its unique parlay generator. Basically, the app will automatically generate random sequences of bets, which you can add and remove wagers from until an ideal combination is formed. Further, players can use the generator to concoct cross-sport parlays, as well.

Note that bonus bets expire in seven days, and each new customer can only claim one offer. Additional terms may apply.

Crab Sports Sportsbook MD Bonus

Bonus: 100% Profit Boost on First Bet up to $500

That’s just the beginning, though. DraftKings also offers free-to-play contests for real prizes, social groups where you can see what your friends are betting on, and a deep well of markets to bet on.

Plus, the DraftKings app is one of the best in the business. It’s fast, responsive, and easy to use. In short, there’s a whole pile of reasons to use DraftKings in Maryland.

How to use Maryland sports betting bonuses, promo codes

When claiming a bonus at a Maryland online sportsbook, there are a few steps to follow.

1. Click “Play Now” at one of the sportsbooks above.
2. Register for an account in the new window and fill in the necessary information. Then, if applicable, enter the assigned promo code, which is also listed above. Sportsbooks sometimes do not require a code to claim a bonus (e.g., you can just use our links to get FanDuel welcome offer with no code needed).
3. Deposit funds into the account. Sportsbooks will typically include a minimum or maximum deposit amount for their promotions. The minimum amount tends to sit between $5-10.
4. At this stage, the next step depends on the specific bonus you’re claiming. With a deposit match, for example, you should see the extra money in your sportsbook account. On the other hand, bonus bets will often be in a standard betslip or the ‘promotions’ section of the app.
5. Finally, meet all playthrough requirements, if applicable.

In essence, a playthrough requirement is a multiple of the total value of the promotion that you must wager before withdrawing any remaining bonus money. For example, if the promotion you choose has a total value of $100 and a playthrough requirement of 10x, you must place $1,000 in wagers to make the bonus funds eligible for withdrawal.

In Maryland, however, most sportsbook bonuses only have a 1x playthrough requirement.

Below are the types of bonuses you may commonly encounter at a Maryland online sportsbook.

No deposit bonus

The no deposit bonus is likely to be your best friend, no matter which sportsbook you engage with. There’s also a good chance that it’ll be the first type of bonus you encounter. In most cases, registering for an account is the only requirement for claiming this type of bonus.

Simply put, no deposit bonuses are the ideal first foray into a new sportsbook.

No deposit bonuses will commonly appear in your account as either bonus dollars or bet credits. This way, they are not a form of cash that can be withdrawn, because doing so would encourage players just to withdraw and never play with the sportsbook. Remember, it is a business after all.

That said, such a restriction is in no way a deterrent. It’s an incentive to redeem any no deposit offer available to you. Any winnings generated from playing with the funds are yours to keep and can play a leading role in getting your bankroll started.

You can activate this type of bonus in one of two ways: enter a promotional code into its allotted section during registration or follow a secure link from a specific source (i.e., the links above).

Deposit bonus

Deposit bonuses are among the more common types of bonuses that sportsbooks offer. In short, the sportsbook agrees to commit a certain amount to complement a player’s initial deposit. Typically, said amount will be a specified percentage of the initial deposit.

This percentage will vary depending on the sportsbook. Some may offer to match a smaller portion of the deposit, say 20%, while others may feel generous and contribute 100%. To that point, sportsbooks will always cap players’ total bonus dollars, regardless of the percentage.

Otherwise, an uncapped bonus would be of great liability to the sportsbook.

Lastly, deposit bonuses are often synonymous with playthrough requirements. A sportsbook may give players a window to meet such requirements, usually a week or two, but that number is open to the operator’s interpretation.

Bonus bet

Considered one of the more popular promotional offerings, bonus bets are more than just a sign-up bonus. Sportsbooks tend to hand out bonus bets fairly often as either a reward for strong betting activity or an incentive to awaken dormant accounts.

And there are more ways to earn such bets than having them tied to your betting volume. For instance, if the sportsbook offers a bonus first bet, and the first bet you place loses, you’ll receive a refund in the form of a bonus bet or bets. Look to BetRivers’ bonus as a real-life example.

Bonus bets will often appear directly in your bet slip. As such, the next time you select a wager, the betting slip will allow you to choose whether the bet is placed with deposited funds or the bonus bet.

Think of this type of bonus as a form of site credit that players can use to place wagers and win real money (minus the initial stake, which the sportsbook covers).

Odds boost

An odds boost, which is another popular sportsbook offering, is an artificial inflation of the payout associated with a particular bet. Common to moneyline wagers, this type of bonus allows sportsbooks to encourage wagering on a particular match. More often than not, odds boosts will appear as a “correction” to existing moneylines. For example, a wager set at +300, may have a line drawn through it, with the new +320 boosted line now taking its place.

The caveat with odds boosts is that they are a reflection of a particular sportsbook’s valuation of a wager. The motivation for offering a boost is entirely at the discretion of the operator, and therefore may not align with a player’s determination of best possible value.

While nobody is getting rich with odds boosts, there are times when they present legitimate value. For example, if you were already planning on making a similar bet to the promotional boost, say a futures bet on a team to win their division, there’s no reason not to take the better odds and increase the potential payout. Odds boosts typically raise said payouts between 15% and 35%, give or take.

Players can often find odds boosts in their own ‘odds boost’ section on a given sportsbook’s app or website. Certain operators will load dozens of boosts onto their platform each day, so keep an eye out in case something of value pops up.

Loyalty program

Sports betting bonus loyalty programs function similarly to that of your favorite restaurant or department store. Players receive points in connection with their wagering (i.e., purchasing) activity, and then may redeem those points for benefits within the app. It’s also possible that loyalty program rewards may extend to any land-based locations associated with an online sportsbook.

Typical sports betting rewards include bonus bets, refunds on net losses, invitations to special events, and even gifts.

Players can unlock these rewards in a multitude of ways, most of which are unique to the sportsbook they’ve chosen. Most operators’ loyalty programs will come in three ways: a points-based system, multi-tiered progression, or crossover loyalty rewards.

If something like crossover loyalty rewards appeals to you, check out BetMGM’s welcome offer, which supplies rewards points that can go towards the resort side of MGM’s holdings.

Common Maryland sports betting bonus terms and conditions

Before getting ahead of yourself, it’s integral to remember that all sportsbook bonuses and promotions have a set of terms and conditions. Each sportsbook will attach its specific terms and conditions to the promotion you are attempting to activate. That said, the documents are usually quite long and filled with legal language, so we’ve gone ahead and broken it down for you.

Here are some of the common terms and conditions typically associated with bonuses and promotions.

Promotional periods

Bonuses and promotions may only be available to qualifying customers for a certain time, as decided by the operator. For example, BetMGM’s bonus bets welcome offer is only valid from Jan. 1, 2022, to December 31, 2023. However, that timeframe can change at the sole discretion of the operator, so if that’s the bonus you like best, move quickly.

Additionally, any accounts opened before or after the indicated promotional period will not qualify under BetMGM’s terms and conditions.

Conversely, promotional periods may also be a window that begins counting down once you open an account. For example, after you’ve signed up you might get 30 days to active your welcome bonuses, or else you lose them. Some sites only give you seven or 14 days. Be sure to pay attention to any deadlines associated with welcome offers or bonuses.

Eligibility requirements

Specific eligibility requirements, such as being of legal gambling age (21), are universal to all operators under state laws. Other baseline requirements include:

• Being present in a jurisdiction where online sports betting is permitted
• Not being on any exclusionary lists, including government programs. Here, both the operator and player may use their discretion to determine whether a player is eligible to play.
• Ensuring that all data provided to the operator is verifiable, i.e., home address, age, banking information, etc.

Eligibility requirements also extend to the games in which a bonus or promotion can be applied to. For example, BetRivers outlines three conditions about its welcome bonus offer:

• Bonus bets only apply to the sportsbook (this doesn’t affect Maryland players, as online casinos are illegal in the state).
• Bonus bets can only be placed on any offering with odds of -200 or higher (i.e., -100, +150). For parlays, each leg must have odds of -200 or higher.
• House specials are ineligible to be used with bonus bets. Further, players cannot combine bonus bets with any other promotions.

Claiming Requirements

The claiming requirements for bonuses and promotions tend to combine multiple conditions. Don’t worry, they’re not difficult to understand.

First and foremost, open an account within the allotted promotional period, as stated on the sportsbook you’ve chosen. From here, you may have to meet a minimum deposit requirement, but the number is commonly quite low. For the four sportsbooks above, the minimum deposit is $10.

Then, you’ll need to place an initial cash wager to receive the bonus or promotion. However, the result of said wager will determine whether or not you receive the bonus or promotion.

For example, if the cash bet you place is successful, you’ll only receive the winnings and not the bonus credit. If the cash bet you place loses, the bonus or promotion unique to the sportsbook will become active in your account. This, again, goes for all operators listed above.

Notably, Caesars will still provide 1,000 reward credits and 1,000 tier credits, win or lose, as long as all other requirements are met.

Limitations and Restrictions

Some limitations and restrictions are fairly obvious but still warrant a brief explanation.

For starters, customers can only enter bonus and promotion codes once. Similarly, bonus bets are strictly for one-time use, for example, one straight bet or one parlay, and cannot be split between multiple wagers.

There is also a cap on the number of bonus bets available to each person, account, household (IP address) and/or computer. This number will vary between operators.

Players cannot redeem bonus bets for cash, withdraw them from their account, or cash them out. Bonus and promotional funds can only be used to place wagers, where then, any subsequent winnings can be withdrawn.

Finally, bonus bets and promotions are non-transferable and do not apply to any other operator accounts you may have. They will not count towards qualifying for any other promotional offers unless expressly stated in the terms and conditions.
