"BetMGM is one of the best sportsbooks and sportsbook apps. The app is miles better than it was a year ago as far as performance goes. It has very competitive odds, a great variety of wagers, and very quick payouts. Deposits and withdrawals are painless, as there is no hassle like you get from other sportsbooks.”

- Randall, Google Play Store user

"BetMGM's bonuses and promotions are good, as they have clear rules, obvious expiration dates, and are easy to apply on a wager. Synchronization with the broader MGM rewards program is seamless and easy to track."

What we like

Access to BetMGM Rewards: When you register to claim this offer, you will be automatically enrolled in the operator’s two affiliated sportsbook loyalty programs — BetMGM Rewards and MGM Rewards — and can earn an array of additional perks with every bet you place at BetMGM.  

Reasonable minimum requirements: Though you must deposit and wager $1,500 to receive the full value of this welcome offer, you can also secure the bonus with only a $10 initial investment. 

Use bonus across multiple wagers: You’ll receive the bonus in five (5) 20% denominations equal to your qualifying stake if your initial unsuccessful wager is more than $50, allowing you to spread the funds across multiple future bets.

What we don't like

More suited to high rollers: You need to deposit $1,500 initially to maximize this offer, making it more attractive to high rollers and seasoned bettors as opposed to those new to online sports betting.  

Slower payouts: BetMGM typically takes up to two banking days to process any withdrawal requests, meaning you'll be waiting longer to receive any future winnings derived from this bonus than you would be with many of its competitors.

""I had an initial hurdle with signing up and getting age verified. It took longer than my other sportsbooks. Eventually, I had to deal with support. They did a great job, though, and I'm finally able to log in and deposit funds. The app looks great; I like the layout, which is simple and fast."

Caesars Sportsbook iOS app

What we like

10x 100% profit boosts, each worth up to $2,500: This Caesars Sportsbook offer stands out because of its sheer maximum value. Not many sportsbooks provide over $1,000 bonuses.

Caesars Rewards: Whether your initial bet wins or loses, you can still earn Caesars Rewards points when placing your qualifying wager for this offer. You can redeem your Caesars Rewards points for lucrative perks, such as bonus bets and a free yearly vacation. 

Low initial investment: Though the amount you earn from this Caesars promo depends on how much you initially invest, knowing that you can still secure the promo for just a $10 minimum deposit and a modest $1 minimum wager, makes it accessible to more bettors. 

What we don't like

First bet must lose: The bonus will not trigger unless your initial wager flops. If it's successful, you'll just receive the winnings instead.

Unideal bonus: We prefer standard 'bet and get' offers than reward straight bonus bets, instead of profit boosts.

3. bet365 - Best dual offer

Choose: $150 Win or Lose or $1,000 Bonus

Code: COVERS

Code: CVSBONUS (CO, IL NJ, PA, TN only)

Claim $150

$1,000 First Bet Safety Net 

Code: COVERS

Code: CVSBONUS (NJ only)

Claim $1,000

Who it's for

bet365's current 'bet and get' welcome promo is ideal for newbies. You only need to complete two steps to score $150 in bonus bets guaranteed*: Deposit $10 within seven days of creating your account and wager at least $5 on any market with odds of -500 or longer. With terms as straightforward as these, we highly recommend this bet365 welcome bonus if you are new to online sports betting. If you are a high roller who is comfortable making up to a $1,000 initial wager, we'd recommend claiming the $1,000 'first bet insurance' offer since it provides a more lucrative upside.

Bonus terms and conditions

You must register via the bet365 Sportsbook app with our exclusive bet365 bonus code 'COVERS' ('CVSBONUS' if you are in CO, IL NJ, PA, TN).

You must make a minimum initial deposit of $10 to claim the bonus.

 Place an initial $5 wager on any market with -500 odds or greater within 30 days of opening your account to qualify.

Whether your bet wins or loses, bet365 will issue you $150 in bonus bets guaranteed* that can be used on any sports betting market. You'll also receive 50 casino spins in PA.

Your bonus will expire seven days (168 hours) after issuance. 

 These Covers-verified bet365 sports betting promo codes expire at 6:59 a.m. ET on June 3, 2025.

User reviews  

Editor's note: User reviews may be edited for clarity. 

"I really like using bet365, as it offers a wide variety of sports to bet on and has an abundant prop menu. One thing I really like with NBA props is the ‘milestones’ that allow you to bet beyond the Las Vegas line on various stats."

- Francis, Google Play Store reviewer

"I have to give credit where it’s due — bet365 and its team have created the best, unique, fastest, and aesthetically pleasing sports betting application. The ball tracking and pitch animation features are excellent. The goal animation is also so much better than every other app out there. Things like this make a difference when you’re tracking a game, and the team you need scores a goal. It’s exciting and immersive, as betting should be. Well done to bet365 for creating the best sports betting app out there. This is the reason why it is my favorite bookmaker."

bet365 iOS app

What we like

Reasonable initial cost: You only need to invest $10 of your own money in order to maximize the full value of this bet365 welcome bonus, which is less than you'll need to deposit at other sportsbooks.

Guaranteed bonus: Whether your first bet hits or misses, you’ll still receive the $150 in bonus bets once your qualifying wager settles.

Future betting flexibility: The bonus funds do not have any market restrictions, meaning you can wager it on any available sports betting events or bet types that bet365 offers. 

What we don't like

Limited window to use bonus: bet365 only allows you seven days (168 hours) to use the funds you earn from this welcome bonus before they expire, which can be a tight window of time if you're a casual bettor.

Low total value: Though we enjoy sports betting promos that are guaranteed, the $150 offered by bet365 is lacking in total value when compared to welcome offers from top competitors like BetMGM and Caesars Sportsbook. 

We've provided a more in-depth analysis of the operator in our bet365 review, which highlights the latest bet365 bonus code required to claim its welcome offer. 

4. FanDuel - Best sportsbook for bonus bets

Bet $5, Win $200

New customers only. Deposit min. $5. Place first bet of min $5 and get $200 in bonus bets if your bet wins.

Claim $200

Who it's for

FanDuel’s welcome bonus is an ideal new-user offer, whether you’re a high roller, an occasional bettor, or a complete newbie. Sportsbook bonuses of this nature are rare, so unless you prefer to hold out for a larger "boom or bust" offer, we recommend claiming this bonus bet offer today. 

Bonus terms and conditions

You must download the FanDuel Sportsbook app to claim the welcome bonus.

Make a minimum deposit of $5 into your new account.

 Place an initial $5 real money wager on any available market. If your wager wins, FanDuel Sportsbook will award $200 in bonus bets within 72 hours of bet placement. New users in AZ, CO, KS, NC, and TN will receive the bonus regardless if their initial wager wins or loses.

If you win a wager using your $200 in bonus bets, the bonus amount will not be returned as part of your winnings. For example, if you use your $200 bonus on a betting market with +100 odds and win, you will receive $200 in withdrawable cash — not $400.

Your bonus bets are valid for seven days (168 hours) after issuance.

 This Covers-verified FanDuel Sportsbook promo expires at 11:59 p.m. ET on June 22, 2025.

FanDuel iOS app

What we like

Mobile app: You must download the FanDuel Sportsbook mobile app in order to claim the welcome bonus. Though this may seem like a hassle, the mobile FanDuel platform is second to none in terms of betting apps with bonus bets, allowing you to easily claim the offer and wager it on various betting markets within a few swipes. 

Straightforward terms: An initial $5 deposit and a successful $5 wager on any sports betting market is all you'll need to score the FanDuel welcome bonus. 

Future flexibility: FanDuel has no market restrictions attached to this offer, allowing you to use the funds on any available betting market. 

What we don't like

Low total value: FanDuel’s welcome bonus lacks the total maximum value that many of its competitors — like Caesars and Fanatics — present with their current new user promos.  

Browse our FanDuel review for an unbiased look at this great online sportsbook and our FanDuel promo code page to learn about the available bonuses you can claim in 2025.

5. Fanatics Sportsbook - Best safety net bonus

$1,000 in No Sweat Bets

New customers only. Deposit min. $5. Choice of three offers. Daily bonus issued within 72 hours.

Claim $1,000

Who it's for

We believe this bonus is best suited for all sports bettors. Those who are more experienced can bet a maximum of $100 per day for 10 consecutive days to fully maximize the bonus. At the same time, casual bettors can still score the bonus by wagering as little as $1 per day. You can also change the amount of your daily wager, which provides complete freedom and flexibility to all bettors.

Bonus terms and conditions

You do not need a Fanatics Sportsbook promo code to score this offer.

A minimum $10 deposit and $1 wager is required.   

 Place a daily wager of at least $1 on any market with -500 odds or longer. If your wagers lose, Fanatics Sportsbook up to a $100 bonus bet per day for your first 10 days using the platform.

The non-withdrawable bonus is awarded regardless of the result of your daily Fanatics Sportsbook qualifying wager and expires after seven days (168 hours).

This Covers-verified Fanatics Sportsbook promo expires on May 31, 2025.

"I really enjoy everything Fanatics Sportsbook has to offer! I really like how you get Fanatics rewards faster than DraftKings, too! I would highly recommend it."

- Justin M., Google Play reviewer

"I really like the Fanatics Sportsbook and the promos it offers from time to time, especially the jersey credit! It has a lot of choices to bet on — from teams, spreads, totals, play props, and special parlays. I’ve deposited and withdrawn and haven’t had any problems, as it was all pretty quick. I love the fact that you can earn FanCash from making bets and can use its' sportsbook offers to redeem points for sports gear!"

What we like

Daily first bet match: The Fanatics Sportsbook offer matches your first bet of the day if the wager loses, meaning you’ll always have funds in your account for your first 10 days using the platform.

FanCash: You earn FanCash with every Fanatics Sportsbook bet you place, which is redeemable at the Fanatics website for sports merchandise. The amount of FanCash is tied to the odds of your wager — 1% for -110 and a maximum of 10% for -6000 — win or lose.

Minimal initial investment: Though the Fanatics Sportsbook bonus has a high total value, you only need to make an initial $10 deposit and $1 daily qualifying wagers to activate the offer.

What we don't like

Daily wagering: You must make a qualifying wager for 10 straight days to maximize the Fanatics Sportsbook welcome offer. If you forget to place your bet, you will void the bonus for that day. 

Difficult to track bonuses: We've found keeping track of the bonus funds you receive from this Fanatics Sportsbook can be slightly confusing since the amount you earn can change every day. Additionally, each bonus also expires seven days (168 hours) from issuance, meaning that you will have up to five separate end dates to keep track of. 

Our Fanatics Sportsbook review provides an extensive look into this emerging operator that offers one of the best sportsbook promos in 2025, which does not require a Fanatics Sportsbook promo to claim. 

6. DraftKings - Best bonus for NBA fans

Bet $5, Get $200 Instantly

New customers only. Deposit min. $5. Place first bet of min. $5 and get $200 in bonus bets.

Claim $200

Who it's for

We recommend this DraftKings Sportsbook promo — one of the best NBA betting promos for the ongoing NBA Playoffs — to any sports bettor because similar to most ‘bet and get’ sports betting offers, it ensures future wagering flexibility, which is something that we target when making the list of the best sportsbook promos. You can use your eight bonus bets on eight future wagers, resulting in a potentially lucrative return on your initial $5 investment.

Bonus terms and conditions

No DraftKings promo code is required to secure this offer.

Make a minimum deposit of $5 and wager of $5.

 If your wager wins or loses, you will receive $200 (eight $25 bonus bets) instantly. 

The bonus is not included in any future winnings.

Your bonus funds are valid for seven days (168 hours) after issuance.

DraftKings iOS app

What we like

Minimal initial buy-in: A measly $5 initial deposit and $5 wager is all you need to invest to secure this DraftKings welcome bonus, making it very accessible for all types of sports bettors.

Automatic account boost: Unlike some online sportsbooks that offer a ‘bet and get’ welcome bonus that requires you to hit on your initial wager, you will receive the $200 bonus regardless of the outcome of your first bet.

Bonus structure: DraftKings issues the promo as eight $25 bonus bets, allowing you to spread the funds across multiple future wagers to increase the likelihood of winning.

What we don't like

Low total value: Though the bonus is guaranteed, we wish DraftKings aligned with its competitors and provided new users with more than just $200 for signing up. 

Seven days to use bonus: Unfortunately, the sports betting offers' bonus funds are only valid for seven days (168 hours) days from the date of receipt, meaning you must act quickly to ensure your bonus doesn't expire.

Up to a $500 Second Chance Bet

Code: COVERSBONUS

Who it's for

We recommend BetRivers Sportsbook's current welcome offer to all bettors who have yet to try out the platform. This ‘second chance bet’ type of sportsbook promo allows you to place your first bet confidently, knowing you’ll receive the entirety of your stake back in bonus bets if it is unsuccessful. We also appreciate the offer’s required minimal initial investment, as you can wager as little as $10 to secure the bonus.

Make a minimum deposit of $10.

 Place an initial wager of up to $500 ($250 in CO and NJ; $100 in AZ, DE, IA, NY, OH, and WV), and BetRivers will return your entire stake if you lose.

Your must wager your BetRivers Sportsbook bonus on any sports betting market with -200 odds or longer.

Straightforward terms: Whether you’re a first-time bettor or a seasoned shark, you just need to register with our exclusive bonus code and make the minimum initial deposit and wager to secure this offer.

Extended promotional window: BetRivers allows you up to 30 days to use the bonus bet, which is longer than some of its competitors who require you to use the funds within a week. 

What we don't like

You don't receive a bonus if you win: The downside of all ‘second chance bet’ or ‘first bet insurance’ welcome offers like this is that you don’t get any type of bonus if you win your initial wager.

Amount depends on location: Only new bettors in seven states (IL, IN, LA, MD, MI, PA, and VA) can receive BetRivers' up to $500 offer, meaning that new bettors in the other legal jurisdictions must settle with a less-valuable welcome promo.

How to get your sportsbook promo

Redeeming the best sports betting promotions for new users in 2025 takes very little time and effort when you follow the steps we've outlined below:

Popular types of sports betting promos

Each of the top U.S. sports betting sites offers great betting promos for new users. We've outlined a few of the most common welcome promotions — bonus bets, second chance bets, deposit and no-deposit matches — you're likely to come across when signing up for a sportsbook in 2025. 

How do 'Bonus bets (bet and get)' offers work?

Bonus bets are one of best sports betting promotions in 2025, as it provides a guaranteed bonus to the new bettors as long as they meet the offer's minimum requirements. Simply make the qualifying deposit and initial wager, and the online operator will issue you bonus bets, typically ranging between $100 and $200, into your newly created account.

How do 'Second chance bet' offers work?

Second chance bets are an excellent way for new bettors to place their initial wager with confidence, knowing that if their first bet fails, the sportsbook returns the amount wagered up to a specified number. The typical safety net for this promo is between $500 and $1,500. We consider this to be one of the best sportsbooks promos for new users since they give users two chances to make a good first impression.

How do 'Deposit match' offers work?

Often referred to as a cash bonus, a deposit match bonus is arguably the most common sportsbook bonus out there and is frequently tethered to sign-up offers. Online sports betting sites will match your deposit up to a specified dollar amount, and it is not unusual to find a 100% match rate if you are a first-time customer.

The currency a sportsbook will provide to your account via a deposit match bonus may vary. Bonus bets and site credit are typical, but you may be offered real cash instead in some instances.

How do 'No deposit bonus' offers work?

While it's is extremely rare, we consider a no-deposit bonus the most sought-after type of sportsbook bonus — it’s the closest a bettor can get to placing a bet with zero risk. Simply sign up, and your account will be credited with — usually a small amount — of bonus money.

Typically, no-deposit bonuses are now tendered as pre-registration offers, which online sportsbooks provide when a state is set to open its doors to legal sports betting for the first time. Keep track of states with legal sports betting and which ones may vote in favor of legalization in the future.

Sportsbook bonuses for existing users

There's a world beyond sportsbook welcome and sign-up bonuses. Some of the best bonuses from betting sites are ongoing promotions, including profit boosts, odds boosts, and reload bonuses. Plus, registering with operators that offer the best sportsbook rewards programs in 2025 can help you score exclusive sports betting bonuses and promos, too. We've outlined several of the best sportsbook odds boosts and promos current bettors can claim for Super Bowl 59:

Odds boost

In sports betting terminology, a boosted odds bonus represents what it purports to be — a sportsbook bonus in which the value of odds on particular wagers has increased. These can occur regularly depending on the operator and include the likes of Over/Under (totals), moneyline, point spread, prop bets, and same-game parlays.

When a specific sportsbook market posts ‘boosted odds’, the line is more advantageous for the user on a seemingly surefire bet. For example, if the Buffalo Bills were playing the Houston Texans, and the line was set at +220 boosted odds for the Bills to win.

Given the likelihood of Buffalo beating Houston, regular odds would line up at -110 for the spread. Sportsbooks sometimes provide boosted odds for either a user reward or promotional purposes. We encourage players to take advantage of a boosted odds market when presented with the opportunity, as your odds of profiting will be more likely than usual.

Reload bonuses

Some online sportsbooks offer their users reload bonuses, meaning they will receive additional site credit each time they replenish their account balance with real cash. Some reload bonuses are deposit matches, while others are bonus bets on specific markets.

For example, a sportsbook may award a $10 bet to any NFL Super Bowl 59 market for every $50 of real cash deposited into an account balance. If it’s a deposit match reload bonus, they may offer to match up to 50% of a deposit during each reload transaction.

Reload bonuses are available exclusively to existing customers who have already received their sign-up bonuses. Sportsbooks will offer these ongoing promotions — frequently or less frequently, depending on the operator — to satiate their users by providing them with boosts to their bankrolls.

Much like many sign-up bonuses, reload bonuses usually come in the form of deposit matches and are activated by making a new deposit. But unlike sign-up bonuses, the match rates for reload bonuses tend to be low — typically 10-15%.

Referral bonus

Sports betting sites are keen to attract new players and often reward existing customers for their recruitment efforts. Already registered players stand to earn a sportsbook referral bonus for any referrals, resulting in a sign-up and real money minimum deposit. Most sportsbooks give registered users a unique referral code that can be distributed amongst friends and family. If someone registers and enters a previously registered user’s referral code during sign-up, both parties will likely receive some kind of referral bonus.

Our pick for the top refer-a-friend bonus comes from FanDuel Sportsbook:

Up to $75 Referral Bonus

No code required

Claim $75

FanDuel has the best betting app promos in 2025 thanks to its strong refer-a-friend program. Send a referral link provided by FanDuel to your friend, have them sign up, and place a wager of $10 or more, and you'll both be rewarded with $75 in site credit. There is a 10-person maximum referral limit per user.

Common sportsbook bonus terms and conditions

Whether you're claiming sport betting offers or an online casino bonus, all promos come with specific terms and conditions that you should read carefully before claiming. Failure to do so could result in forfeited bonuses. 

We've outlined several pitfalls to avoid when claiming sports betting promos and bonuses.

Allowing promotions to lapse

Most operators will only give you a short time frame to use your bonus — usually between seven and 14 days. If you have unused bonus bets after the specified time, the sportsbook will remove them from your account

Overlooking rollover requirements

Some sportsbook promos come with rollover — or "wagering" — requirements. Look for "5x" or "10x" in the terms and conditions. The number before "x" indicates the number of times you have to wager your initial deposit, bonus, or both.

Neglecting minimum odds requirements

Sportsbooks may attach a minimum odds requirement to your initial wager, meaning a bet placed on shorter odds will not unlock a bonus. If terms indicate you must wager on minimum -200 odds, be sure to lock in your bet on -175, -150, +100, or longer odds.

Betting on ineligible markets

If your qualifying wager has to settle within seven days, futures bets may not be an option. If terms and conditions allude to same-game parlays, you may not be able to place single-game wagers with your bonus bets. Check out the list of ineligible markets to ensure you're aware of market limitations.

Not maximizing value 

While $1,000 bets aren't for everyone, understanding the full scope of sports betting offers will put you in a position to make an informed decision when it comes to how much you deposit and wager. For example, there's no need to place a $100 wager if it takes only $5 to earn you $200 in bonus bets.

Sports betting promo codes and bonuses by state

The number of states where online sports betting is legal continues to climb. However, not all will offer the sports betting promos identified within this guide. Why not? Certain states limit the number of licensed operators they allow to take bets within their borders.

Betting sites to avoid

If it seems too good to be true, it probably is. There are plenty of suspect online sportsbooks and operators looking to steal your business from reputable betting sites. Avoiding these illegal offshore sportsbooks is essential as it’s nearly impossible to recover any unpaid winnings from them. You can take a closer look at these unregulated sportsbooks via our blacklist. 

• Allegations of withdrawal issues
• No license information available on site
• Poor customer service

• Multiple reports of slow payments
• Allegations of non-payments
