Let's dive into the offshore sportsbooks that offer the most compelling welcome packages in 2025.
1. MyBookie: Generous Bonuses and a User-Friendly Experience
MyBookie has carved out a significant space in the competitive offshore betting market by combining some of the best sportsbook bonuses with a platform that is exceptionally welcoming to both new and experienced bettors. Its main appeal lies in its straightforward bonus structures and a user interface that makes navigating odds and placing wagers a seamless process.
Standout Bonus Offer
MyBookie's primary welcome offer is a 100% Sign-Up Bonus up to $1,000. This is a direct deposit match, meaning if you deposit $500, you receive an additional $500 in bonus funds. The real value here is the manageable 10x rollover requirement, which is more favorable than the industry average. Many competitors, like some offers at BetOnline or Bovada, can have higher rollovers, making MyBookie’s offer particularly attractive for players who want to clear their bonus without excessive wagering.
To claim this offer, simply use the promo code MYB100 during your first deposit. The minimum deposit to qualify is a reasonable $50.
Key Features and User Experience
MyBookie excels in its simplicity and accessibility. The website design is clean, with clear menus for sports, live betting, casino, and horse racing. This makes it an ideal starting point for bettors who might feel overwhelmed by the complex interfaces found on other platforms.
- Crypto Reload Bonus: For returning players, MyBookie offers a 150% Crypto Reload Bonus up to $1,500. This is a massive incentive for cryptocurrency users, positioning it as a top choice alongside other crypto-friendly sites like BetUS.
- Contests and Promotions: The platform regularly runs unique contests, especially around major events like the Super Bowl or March Madness, offering large prize pools that add an extra layer of excitement.
- Customer Support: MyBookie provides 24/7 customer support via live chat and email, ensuring users can get help whenever needed.
Pro Tip: When aiming to meet the rollover requirement, focus on straight bets with favorable odds (-200 or less) rather than high-risk parlays. This strategy helps you systematically work through the requirement while preserving your bankroll.
While its odds may not always be the absolute sharpest compared to a professional-focused site like Bookmaker.eu, MyBookie’s blend of generous bonuses, a low rollover, and an intuitive platform makes it a top-tier destination for the majority of US bettors.
2. BetOnline: A Powerhouse for Reloads and High Bonus Caps
BetOnline has established itself as a titan in the online betting world, renowned for its competitive odds, fast payouts, and some of the most consistently valuable sportsbook bonuses available. It particularly shines for its commitment to rewarding both new and loyal players, making it a go-to platform for bettors who plan to stick around long-term.
Standout Bonus Offer
BetOnline’s flagship welcome offer is a 50% Welcome Bonus up to $1,000. While the percentage is lower than some competitors like MyBookie or BetUS, the accessible 10x rollover requirement keeps it highly competitive. This bonus is ideal for bettors making a substantial initial deposit who want a clear path to cashing out their winnings without being tied to overly restrictive terms.
To claim this bonus, use the promo code BOL1000 on your first-ever deposit. The minimum deposit is $55, which is slightly higher than average but reasonable for the bonus size.
Key Features and User Experience
BetOnline’s platform is robust and feature-rich, catering to serious bettors while remaining navigable for newcomers. Its recent site redesign has significantly improved the user experience, making it cleaner and more intuitive than older versions. The dedicated "Promos" tab clearly outlines all available offers, a feature that simplifies bonus management.
- Lifetime Reload Bonus: BetOnline's standout feature is the 25% Sports Reload Bonus (up to $250) available on every qualifying deposit for life. This ongoing value is nearly unmatched and a major reason it competes so well with sites like Bovada for player loyalty.
- Crypto Boosts: The platform heavily incentivizes crypto deposits, offering a 100% 1st Time Crypto Bonus and subsequent crypto reloads, often with better terms than traditional deposit methods.
- Contests and Odds Boosters: BetOnline frequently runs million-dollar contests for major events and provides daily odds boosters, giving players more ways to win.
Pro Tip: To maximize value at BetOnline, plan your deposits to take full advantage of the lifetime reload bonus. Instead of making one large deposit after your initial one, consider smaller, more frequent deposits to consistently claim the 25% match.
While its main welcome bonus has a slightly higher minimum deposit, BetOnline's combination of lifetime reloads, high bonus caps, and a polished user interface makes it an elite destination for bettors seeking long-term value.

3. BetUS: America's Favorite Sportsbook with a "Crypto First" Mentality
Dubbed "America's Favorite Sportsbook," BetUS has built a strong reputation over more than 25 years by offering some of the best sportsbook bonuses in the offshore market, particularly for cryptocurrency users. The platform expertly blends traditional sports betting with deep analysis and media content, creating a comprehensive experience for bettors who value both generous promotions and informed wagering.
Standout Bonus Offer
BetUS's flagship offer is a massive 200% Crypto Sign-Up Bonus, which is split between the sportsbook and casino. This breaks down as a 150% Sports Bonus up to $3,750 and a 50% Casino Bonus up to $1,250. This hybrid structure is a major draw for players who enjoy both sports and casino gaming, offering more combined value than the sports-only sign-up bonuses at competitors like Bovada or Sportsbetting.ag.
To claim this, use the promo code JOIN200 on your first crypto deposit of $100 or more. The sports bonus comes with a 15x rollover, which is competitive for an offer of this size.
Key Features and User Experience
BetUS stands out with its content-driven approach, featuring "BetUS TV" with expert analysis and picks, which adds significant value beyond just placing bets. The platform is well-organized, making it easy to find sports, live betting, and ongoing promotions. It has also become well-known for its seamless user experience on mobile devices.
- Massive Reload Bonuses: Returning players can claim up to a 100% Crypto Re-Up Bonus, ensuring that the promotional value continues long after the initial sign-up.
- BetUS TV: Provides free expert picks, game previews, and analysis, helping bettors make more informed decisions-a unique feature not commonly found at other sportsbooks like Xbet.
- Loyalty Program: A tiered rewards program that offers exclusive perks, larger bonuses, and contest entries for consistent players.
Pro Tip: Leverage BetUS TV's expert analysis to identify value bets. Combining their free picks with your own research can be a powerful strategy for clearing the 15x rollover requirement on the welcome bonus.
While its bonus structures are heavily geared toward crypto depositors, the sheer size of the promotions at BetUS makes it an essential destination for anyone looking to maximize their bankroll with one of the best sportsbook bonuses available today.
4. Xbet: High-Value Reloads and a Competitive Welcome Offer
Xbet stands out in the crowded offshore market by offering a balanced combination of a solid welcome bonus and some of the best sportsbook bonuses for returning players. It caters to bettors who appreciate consistent value beyond the initial deposit, positioning itself as a strong alternative to platforms known for single, large-scale promotions.
Standout Bonus Offer
Xbet’s welcome offer is a 100% Sign-Up Bonus up to $500. While the maximum amount is lower than the $1,000 offered by sites like MyBookie or BetOnline, its appeal lies in an exceptionally low 7x rollover requirement. This makes it one of the easiest bonuses to clear in the industry, perfect for bettors who want faster access to their winnings without being tied to extensive wagering commitments.
To claim this bonus, use the promo code XB100 on your first deposit. A minimum deposit of just $45 is required to qualify.
Key Features and User Experience
Xbet shares a similar clean and intuitive interface with its sister site, MyBookie, making it easy for newcomers to navigate. However, it carves its own niche with a strong focus on rewarding player loyalty through its reload promotions.
- Sports Reload Bonus: Xbet offers a generous 25% Sports Reload Bonus up to $250. This consistent offer provides ongoing value, a feature that many bettors look for after they have used their initial welcome bonus.
- Casino Reloads and Rebates: Beyond sports, Xbet provides significant reload bonuses for its casino, making it a well-rounded platform for users who enjoy both types of betting.
- Mobile-First Design: The platform is heavily optimized for mobile use, providing a smooth and responsive experience for betting on the go, rivaling the mobile performance of other top offshore books like Bovada.
Pro Tip: Leverage the low 7x rollover by making your initial deposit count. A $500 deposit maximizes the bonus and only requires $7,000 in total wagers to clear, a much more achievable target than the 10x or 15x rollovers found elsewhere.
While its bonus cap is more modest, Xbet's combination of a user-friendly platform and one of the lowest rollover requirements in the offshore market makes it a fantastic choice for pragmatic bettors focused on real, attainable value.
5. BetUS: “America’s Favorite Sportsbook” with Huge Crypto Bonuses
BetUS has cemented its reputation as “America’s Favorite Sportsbook” by offering some of the largest and most varied sign-up bonuses in the offshore industry. It particularly stands out for its massive crypto-focused promotions, appealing directly to bettors who prefer using digital currencies for their speed and privacy, while also providing a robust experience for traditional players.
Standout Bonus Offer
The flagship promotion at BetUS is its 200% Crypto Sign-Up Bonus, split between sports and casino. This offer includes a 150% Sports Bonus up to $1,875 and a 50% Casino Bonus up to $625. This hybrid structure is perfect for players who enjoy both sports wagering and casino games. While the 15x rollover on the sports portion is slightly higher than MyBookie's 10x, the sheer size of the bonus percentage makes it one of the most compelling offers available.
To claim this, use the promo code JOIN200 on your first crypto deposit. The minimum deposit required is $100.
Key Features and User Experience
BetUS provides a polished and professional platform, complete with its own "BetUS TV" segment offering analysis and picks, which adds significant value for bettors seeking an edge. The site is well-organized, making it easy to find sports lines, live betting options, and ongoing promotions.
- Massive Bonus Variety: Beyond the main crypto offer, BetUS provides numerous other bonuses, including a 125% Sign-Up Bonus for fiat deposits (Code: JOIN125), and specific reload bonuses that give it an edge over competitors like Bovada or Xbet.
- BetUS TV and Locker Room: These unique content features provide expert analysis, betting previews, and articles, which is a rare and valuable resource not commonly found at other offshore sites.
- Strong Customer Support: BetUS offers 24/7 support through phone, live chat, and email, with dedicated lines for different needs, ensuring prompt and effective service.
Pro Tip: With the BetUS crypto bonus, allocate your sports wagers to meet the 15x rollover first. The casino portion has a 30x rollover, so clearing the sports requirement allows you to access those winnings more quickly.
While the higher-than-average rollovers require a more dedicated wagering strategy, the enormous bonus percentages and unique content features make BetUS a premier destination for bettors looking to maximize their initial deposit.
6. Cosmobet: A Futuristic Platform with Stellar Crypto Bonuses
Cosmobet is rapidly making a name for itself in the offshore betting landscape by pairing a sleek, modern interface with some of the most compelling crypto-centric bonuses available. It appeals to a new generation of bettors who prefer using digital currencies and value a platform that feels fresh, fast, and packed with rewarding promotions that go beyond the standard deposit match.
Standout Bonus Offer
Cosmobet’s flagship offer is a massive 150% Crypto Welcome Bonus up to $1,000. This immediately sets it apart from many competitors. While sites like MyBookie and Bovada offer great welcome packages, Cosmobet’s higher percentage match on crypto deposits provides more upfront bonus funds. Depositing $500 with Bitcoin, for instance, nets you an extra $750 to wager with.
The bonus comes with a 15x rollover requirement, which is competitive for a bonus of this size. This structure is designed for players who are serious about crypto betting and understand the wagering commitment needed to unlock such a generous offer. To claim it, simply select the offer during your first crypto deposit.
Key Features and User Experience
Cosmobet’s user experience is one of its strongest assets. The site is visually engaging with a dark theme and futuristic design elements, making navigation intuitive and exciting. It feels distinctly different from more traditional-looking sites, offering a refreshing change of pace.
- Ongoing Crypto Promotions: Beyond the welcome offer, Cosmobet consistently provides crypto-specific reloads and special event bonuses, reinforcing its position as a top destination for digital currency users, rivaling the crypto offerings at BetUS and BetOnline.
- 3+1 Freebet: A unique loyalty promotion where every fourth qualifying bet you place is a free bet. This rewards consistent play and gives bettors a risk-free opportunity to boost their bankroll.
- Modern Interface: The platform is optimized for both desktop and mobile, ensuring a seamless experience whether you're betting at home or on the go. Live betting is particularly well-integrated and easy to use.
Pro Tip: Take full advantage of the 3+1 Freebet offer by making three qualifying straight bets on events you’ve researched well. Use the subsequent free bet on a calculated parlay to maximize your potential return without risking your own capital.
While Cosmobet is still building its long-term reputation compared to industry veterans like Bookmaker.eu, its forward-thinking approach, powerful crypto bonuses, and excellent user interface make it one of the best sportsbook bonuses for the modern, tech-savvy bettor.
7. Covers: Your Central Hub for Comparing Sportsbook Bonuses
Covers isn't a sportsbook itself, but rather an indispensable resource for bettors looking to find the best sportsbook bonuses without the hassle of visiting every site individually. It acts as an independent comparison hub, aggregating the latest offers from top offshore sportsbooks and presenting them in a clear, easy-to-digest format. This saves time and helps you pinpoint the most lucrative promotions available.
Standout Bonus Offer
Covers' primary value is its centralized, editor-verified list of top U.S. sportsbook bonuses. Instead of offering a direct bonus, it provides a comprehensive roundup of promotions from sites like Bovada, BetOnline, and BUSR. You can quickly scan and compare a 125% Sign-Up Bonus from BetUS against a 50% Welcome Bonus from Sportsbetting.ag, all in one place.
The platform provides crucial details like promo codes, minimum deposits, odds restrictions, and bonus expiry windows. This side-by-side comparison makes it simple to identify which offer aligns best with your betting style and bankroll before committing.
Key Features and User Experience
Covers excels at organizing complex information into an actionable format. The site is cleanly laid out, with a focus on providing clear, verified data to help users make informed decisions. It’s an essential first stop for any serious bonus hunter.
- Time-Saving Comparison: The main draw is efficiency. Instead of opening multiple tabs for MyBookie, Xbet, and Bookmaker.eu, you get a bird's-eye view of their current welcome and reload offers.
- Verified and Updated: Each listing includes a "last verified" timestamp, giving you confidence that the promo codes and bonus details are current and accurate.
- Offshore Focus: Covers highlights which sportsbooks are available to US bettors, ensuring you only pursue offers you can actually claim from top offshore sites like BetAnything and Bet105.
Pro Tip: Use Covers to create a shortlist of 2-3 top bonuses. Then, visit the official sportsbook sites directly to double-check the terms and conditions. Offers can change quickly, so always confirm the details on the operator's page before depositing.
While Covers is an affiliate site and doesn’t host the bets itself, its role as a trusted aggregator is invaluable. It empowers bettors by providing the clarity needed to navigate the competitive world of offshore sportsbook promotions effectively.

Making the Smart Play: Choosing Your Ideal Bonus
Navigating the world of online sports betting bonuses can feel like studying a complex playbook, but with the right strategy, you can turn these offers into a significant advantage. As we've detailed, the best sportsbook bonuses are not one-size-fits-all. The ideal choice hinges entirely on your individual betting style, financial strategy, and long-term goals. Simply chasing the largest dollar amount without reading the fine print is a rookie mistake.
A massive 200% crypto bonus from a site like BetUS might seem unbeatable, but its value is directly tied to your ability and willingness to meet the 15x rollover requirement. For a bettor who prefers a lower-risk, faster path to cashing out, the more modest 50% Welcome Bonus from Bovada with its player-friendly 5x rollover is a far superior choice. The key is to look beyond the headline number and analyze the terms that will actually impact your bankroll.
Key Takeaways for Selecting Your Bonus
To effectively choose the right offer, you need to align the bonus terms with your personal betting habits. Consider these critical factors before making your deposit:
- Rollover Requirements: This is the most important term. Are you a high-volume bettor who can comfortably meet a 10x or 15x rollover, like those often found at Sportsbetting.ag or BetUS? Or do you prefer the lower-commitment 5x rollovers offered by sites like Bovada?
- Bonus Type and Percentage: A 100% match from MyBookie effectively doubles your initial bankroll, giving you more ammunition from day one. In contrast, reload bonuses from BetOnline are designed to reward loyalty and keep your account funded over the long haul. Decide if you want maximum upfront value or sustained rewards.
- Your Preferred Deposit Method: Many of the most generous offers, especially those from offshore sportsbooks like Bookmaker.eu and Cosmobet, are tied to cryptocurrency deposits. If you primarily use Bitcoin or other altcoins, you will unlock a tier of promotions that are often unavailable to credit card users.
Ultimately, your goal is to find a bonus that complements your strategy, not one that dictates it. Don't let a high rollover force you into making rushed or uneducated wagers just to clear the requirement. The best promotion is one that provides real, accessible value and enhances your overall betting experience. Use this guide to compare the specifics, weigh the pros and cons, and make an informed decision that sets you up for success from your very first bet.
