Maryland Sports Betting — Offshore Sportsbooks & Betting Alternatives 2025

Updated May 2025 — Expert Verified

Maryland legalized sports betting through a 2020 voter referendum, and mobile wagering has been live since November 2022. The MLGCA and SWARC oversee a competitive market of state-licensed operators. But some Maryland bettors also turn to international offshore sportsbooks that offer different bonus structures, broader market coverage, and cryptocurrency payment options that domestic platforms have not adopted. This guide reviews the top offshore sportsbook platforms available to Maryland residents, leading with those that combine sports betting with casino gaming. While Maryland has a mature legal sports market, these offshore alternatives offer features — massive welcome bonuses, crypto payouts, global market depth — that state-licensed books do not yet match. We present them as informational alternatives alongside Maryland's regulated framework.

Detailed Reviews — Offshore Sportsbooks Available to Maryland Players

#1 — Tenobet — Top Casino + Sportsbook Combo

Tagline: "A modern dual-purpose platform that handles sports and casino under one roof for Maryland bettors."

Welcome Bonus: 400% up to $5,000. 25x wagering. T&Cs apply. Not licensed by MLGCA.

⭐ Rating: 4.8/5

Payment Methods: Credit/debit cards, e-wallets, cryptocurrency, bank transfer.

Pros:

• 400% deposit match with $5,000 ceiling combines massive value with sportsbook access
• 3,500+ casino games alongside a comprehensive sportsbook in one account
• 25x wagering is below average for this bonus size
• Modern interface for seamless switching between sports and casino
• USD denomination eliminates currency conversion for MD bettors

Cons:

• Not licensed by MLGCA or any US authority
• Live betting speed may trail top domestic platforms
• Newer platform still building track record
• Some niche sport limits may be lower than dedicated books

Tenobet tops our offshore sportsbook list because it delivers the strongest combination of sports betting and casino gaming in a single platform. The 400% bonus applies across both verticals — sports wagers and casino games — from one account. The sportsbook covers NFL, NBA, MLB, NHL, college sports, soccer, tennis, MMA, and niche markets with pre-match and live betting. The casino side adds 3,500+ titles. The 25x wagering on a USD-denominated bonus makes this the most practical high-value welcome offer for Maryland bettors seeking dual-product access.

#2 — Donbet — Strongest Sportsbook Focus

Tagline: "A sportsbook-first platform with mafia-themed flair and serious betting depth."

Welcome Bonus: 150% up to £750 + 50 Free Spins. T&Cs apply.

⭐ Rating: 4.7/5

Payment Methods: Credit/debit cards, e-wallets, cryptocurrency, bank transfer.

Pros:

• Sportsbook depth rivals dedicated offshore betting platforms
• 4,000+ casino games complement the sports product
• Distinctive mafia-themed brand identity
• Strong European football, tennis, and international sports coverage
• Live betting across major events with real-time odds

Cons:

• GBP denomination introduces currency conversion for MD players
• Not licensed by MLGCA or any US authority
• 150% match and £750 ceiling are mid-range
• US niche sports coverage may lag domestic books

Donbet is built for bettors who prioritize sportsbook depth. European football receives treatment from top-flight leagues through lower divisions. Tennis, basketball, MMA, boxing, cricket, and rugby all get comprehensive pre-match and live coverage. The 4,000+ casino library adds a strong secondary product, and the mafia-inspired design gives Donbet a distinctive visual identity. For Maryland players seeking an offshore sportsbook with genuine depth and strong international coverage, Donbet stands out.

#3 — Goldenbet — Competitive Sports Odds

Tagline: "Competitive odds and live betting depth for Maryland line shoppers."

Welcome Bonus: Casino + Sports Welcome Bonus available. T&Cs apply.

⭐ Rating: 4.6/5

Payment Methods: Credit/debit cards, e-wallets, cryptocurrency, bank transfer.

Pros:

• Odds competitiveness is the defining strength — strong pricing on major markets
• Comprehensive live betting with real-time odds movement
• Dual welcome bonus covering casino and sports
• Broad sports menu including NFL, NBA, international football, tennis
• Casino games available alongside sportsbook from one account

Cons:

• Welcome bonus specifics less prominently advertised
• Not licensed by MLGCA or any US authority
• Casino game count not prominently disclosed
• Lower brand recognition than more established platforms

Goldenbet emphasizes odds quality over bonus spectacle. For Maryland bettors who line-shop across multiple platforms, consistently competitive NFL spreads, NBA moneylines, and international market pricing delivers real long-term value. Even small odds advantages — the difference between -110 and -105 on a spread, for example — compound into meaningful returns over hundreds of wagers. Professional bettors and value-conscious recreational bettors alike benefit from this pricing discipline.

The live betting product is comprehensive, offering in-play markets across all major sports with real-time odds updates. For Maryland residents accustomed to the live interfaces at state-licensed sportsbooks, Goldenbet provides comparable coverage with the added benefit of broader international availability. Soccer fans will find markets from top-flight European leagues through to lower divisions and regional competitions.

The integrated casino adds cross-product functionality, letting you switch between sports and casino games from a single account. Sports coverage spans NFL, NBA, MLB, NHL, college sports, soccer from global leagues, tennis, golf, MMA, boxing, and niche international markets that domestic books may not cover.

#4 — Freshbet — Live Sports Events Leader

Tagline: "90,000+ live sports events annually for Maryland bettors who want non-stop action."

Welcome Bonus: Up to €1,500 across welcome deposits. T&Cs apply.

⭐ Rating: 4.6/5

Payment Methods: Credit/debit cards, e-wallets, cryptocurrency, bank transfer.

Pros:

• 90,000+ live sports events per year — far more than most competitors
• 3,000+ casino games as secondary product
• Up to €1,500 welcome value across initial deposits
• In-play interface handles high event volume smoothly
• Deep international sports coverage

Cons:

• EUR denomination requires conversion for MD bettors
• Not licensed by MLGCA or any US authority
• Casino library smaller than volume leaders
• Multi-deposit bonus requires sustained deposits for full value

Freshbet's 90,000+ annual live events make it the volume leader for in-play betting among offshore platforms accepting Maryland players. That figure encompasses everything from NFL and NBA games to international soccer, tennis, table tennis, esports, and virtually every competitive sport with a betting market. For bettors who thrive on live action and want around-the-clock access to in-play markets, Freshbet delivers constant availability regardless of time zone.

The live interface is built to handle this volume, organizing events by sport, league, and start time with filtering tools that let you quickly locate target markets. Odds update in real time, and the range of in-play options — spreads, totals, moneylines, next-scorer markets — covers the full spectrum. Pre-match betting is solid across NFL, NBA, MLB, NHL, and international markets with competitive pricing.

The 3,000+ casino games provide a strong secondary product for cross-product play. The €1,500 welcome package across multiple deposits incentivizes sustained engagement rather than a single large deposit. Maryland bettors should factor in the EUR denomination when calculating real USD value.

International platform — not licensed by MLGCA/SWARC. T&Cs apply.

#5 — MyStake — Sports + Casino + Mini-Games

Tagline: "Three products — sportsbook, casino, and exclusive mini-games — in one account."

Welcome Bonus: 150% up to €1,000. T&Cs apply.

⭐ Rating: 4.5/5

Payment Methods: Credit/debit cards, e-wallets, Bitcoin, Ethereum, Litecoin, USDT, bank transfer.

Pros:

• Triple-product platform: sportsbook, 7,000+ casino games, exclusive mini-games
• Chicken and Dino mini-games found nowhere else
• Full crypto support across all products
• Pre-match and live sports betting across major and niche markets
• VIP program with escalating rewards

Cons:

• 150% match and €1,000 ceiling are modest
• Not licensed by MLGCA or any US authority
• Interface can feel busy with three product categories
• Mini-game house edges not always disclosed

MyStake is the most versatile platform on this list. Maryland bettors can wager on NFL pre-match lines, spin slots, play a round of Chicken, and check live NBA odds — all from one login. The sportsbook handles core markets competently, though it does not match Donbet or Goldenbet in pure betting depth. The exclusive mini-games and 7,000+ casino library provide genuine differentiation. Crypto support is comprehensive across all verticals.

International platform — not licensed by MLGCA/SWARC. T&Cs apply.

• Quality varies across 70+ providers
• Platform can load slowly under content weight

Rolletto's 70+ provider network produces the widest game variety of any platform on this list. The sportsbook operates alongside the 8,000+ game casino, covering major US leagues and international sports. Dual crypto/fiat payments accommodate any preference, and the €5,500 welcome bonus rewards sustained engagement across multiple deposits.

International platform — not licensed by MLGCA/SWARC. T&Cs apply.

#7 — Slottio — Crypto-Friendly Sportsbook Alternative

Tagline: "A 450% match and crypto-friendly infrastructure for Maryland bettors seeking offshore value."

Welcome Bonus: 450% up to €3,000. T&Cs apply.

⭐ Rating: 4.4/5

Payment Methods: Credit/debit cards, e-wallets, Bitcoin, Ethereum, Litecoin, bank transfer.

Pros:

• 450% deposit match is among the most aggressive offers available
• €3,000 ceiling provides substantial value for mid-range depositors
• Full cryptocurrency support for deposits and withdrawals
• Broad game selection spanning all major casino categories
• Modern, clean interface without visual clutter

Cons:

• Not licensed by MLGCA or any US authority
• Wagering requirements on the 450% bonus should be reviewed carefully
• EUR denomination requires conversion for USD players
• Sportsbook depth may not match dedicated sports-first platforms

Slottio combines a massive 450% deposit match with strong crypto infrastructure, positioning itself as a high-value option for Maryland bettors who transact in digital currencies. The platform accepts Bitcoin, Ethereum, Litecoin, and other tokens for both deposits and withdrawals, providing a seamless crypto experience alongside its game library.

While casino-primary, Slottio offers sports betting access alongside its games, making it a dual-purpose option for Maryland bettors who want aggressive bonus value paired with crypto flexibility. The interface is clean and modern, avoiding the cluttered layouts common across the offshore sector. The broad game selection spans slots, table games, live dealer, and specialty categories.

The 450% match is the headline draw, and Maryland players should review the wagering requirements carefully to understand the full clearing path before depositing. For crypto-focused bettors who value high bonus percentages, Slottio earns its place on this list.

#8 — Lucki Casino — Fast Payouts as Sportsbook Complement

Tagline: "Rapid cashouts and 4,000+ games for Maryland bettors seeking a casino companion."

Welcome Bonus: 450% up to €5,000. T&Cs apply.

⭐ Rating: 4.3/5

Lucki Casino earns a spot on the sportsbook article as a high-value casino complement for Maryland bettors who use state-licensed sportsbooks for sports and want an offshore casino alongside. The 450% bonus up to €5,000 is among the most generous available, and payout speed is consistently impressive. For MD players who split activity between legal sportsbooks and offshore casino platforms, Lucki is a strong choice for the casino side.

International platform — not licensed in Maryland or any US state. T&Cs apply.

#9 — Kaasino — 10,000+ Games as Casino Complement

Tagline: "The largest game library available to Maryland bettors alongside their sportsbook accounts."

Welcome Bonus: 100% up to €1,000 + 300 FS (total up to €2,500 + 500 FS). 40x wagering. T&Cs apply.

⭐ Rating: 4.2/5

Kaasino's 10,000+ game library makes it the volume leader among offshore platforms. While casino-focused without a dedicated sportsbook, the sheer depth of content makes it a compelling addition for Maryland bettors who want maximum game variety alongside their regulated sports wagering. The multi-deposit welcome package delivers up to €2,500 + 500 free spins for sustained play value.

International platform — not licensed in Maryland or any US state. 40x wagering applies. T&Cs apply.

Tagline: "A polished modern platform for Maryland bettors looking for clean offshore casino access."

Welcome Bonus: Welcome bonus available for new players. T&Cs apply.

⭐ Rating: 4.2/5

Winstler rounds out the list as a modern, well-designed casino platform with multiple software providers. The clean interface, responsive mobile experience, and diverse game categories (slots, table games, live dealer) make it a solid option for Maryland bettors who want a secondary offshore platform alongside their regulated sportsbook accounts. The platform is still building its reputation, but early indications point to a competent operator focused on design quality and provider variety.

Maryland's Legal Sports Betting Landscape

Maryland legalized sports betting through a voter referendum in November 2020 (Question 2, 67% approval). Retail betting launched December 2021; mobile wagering went live November 23, 2022. The MLGCA serves as primary regulator, with SWARC evaluating license applications.

The state issues Class A licenses (up to 30, retail) and Class B licenses (up to 60, mobile-only). Over a dozen licensed mobile sportsbooks currently operate. The legal age is 21, and bettors must be physically present in Maryland (verified by geolocation).

The offshore platforms in this guide operate outside this framework. They are not MLGCA/SWARC licensed, and Maryland law does not explicitly authorize their use. Individual bettors are not typically targeted for enforcement, but these sites offer none of the consumer protections — segregated funds, regulated disputes, responsible gaming mandates — that licensed sportsbooks provide.

Many MD bettors maintain both: licensed books for core wagering, offshore platforms for specific features or markets. If you are interested in casino gaming, Maryland online casinos are not yet legal for real money, though offshore alternatives exist as covered in our casino guide above.

How to Choose an Offshore Sportsbook in Maryland

Step 1 — Determine What You Need

Already have licensed sportsbooks and want casino? Try Tenobet, MyStake, or Rolletto. Want deeper international sports? Donbet, Goldenbet, or Freshbet. Need fast crypto payouts for casino play? Jack Casino or 1Red.

Step 2 — Compare Bonus Value Realistically

Tenobet's 400% at 25x delivers different value than MadCasino's 777% at 30x. Calculate total wagers needed to clear each bonus.

Step 3 — Verify Payment Methods

Crypto offers the most reliable offshore experience. If fiat-only, verify US card acceptance.

Step 4 — Test with a Small Deposit

Deposit the minimum, test the platform, attempt a withdrawal before committing larger bankrolls.

Step 5 — Maintain Licensed Accounts

Offshore platforms should complement, not replace, regulated MD sportsbooks. Use licensed books for protected wagering and offshore for specific features. Sports betting in Pennsylvania offers another comparison for bettors in neighboring states.

Frequently Asked Questions — Maryland Sports Betting

Is sports betting legal in Maryland? Yes. Fully legal since November 2022 for mobile and December 2021 for retail. The MLGCA regulates all licensed operators.

What are offshore sportsbooks and can Maryland residents use them? International platforms licensed outside the US. They accept MD players but are not MLGCA/SWARC regulated. Using them is not a criminal offense for individual bettors, but they offer no state consumer protections.

How old do you have to be to bet on sports in Maryland? 21 years or older at licensed sportsbooks. Most offshore platforms require 18 or 21.

Why would Maryland bettors use offshore sportsbooks? Larger bonuses (up to $7,500 vs. $1,500), cryptocurrency support, casino access (not available at MD licensed books), and deeper international sports coverage.

Can I bet on college sports in Maryland? Yes. College sports wagering is permitted, including in-state teams. Certain player prop bets may be restricted at licensed books.

Which offshore sportsbook has the highest welcome bonus? Tenobet offers 400% up to $5,000 as a combined sports/casino bonus. For casino-only, MadCasino offers 777% up to $7,500. For lowest wagering, Kingdom Casino's 10x at 600% is most clearable.

Do I need to be in Maryland to use offshore sportsbooks? No. Offshore platforms do not use geolocation. For Maryland's licensed books, you must be physically within state borders.

What sports can I bet on at offshore sportsbooks? NFL, NBA, MLB, NHL, college sports, soccer worldwide, tennis, golf, MMA, boxing, cricket, rugby, esports, and more. International coverage typically exceeds domestic books.

How do I deposit at an offshore sportsbook from Maryland? Cryptocurrency is most reliable. Credit cards may work but can be blocked by US banks.

How quickly can I withdraw from offshore sportsbooks? Crypto: 10 minutes (Jack Casino) to several hours. Traditional methods: 1–7 business days.

Do I pay taxes on offshore sportsbook winnings? Yes. All gambling income is taxable under federal and Maryland law. Offshore platforms do not issue US tax forms — record-keeping is your responsibility.

Are offshore sportsbooks safe for Maryland bettors? Safety varies. Reputable platforms hold international licenses and use SSL encryption, but lack MLGCA oversight. Test withdrawals with small amounts first.

Can I use both licensed and offshore sportsbooks in Maryland? Yes. Many bettors maintain both — licensed for regulated protection, offshore for bonuses, crypto, or market coverage.

What is the difference between bonus bets and deposit match bonuses? Licensed MD books issue bonus bets (keep winnings, not the stake). Offshore platforms add matched funds to your balance that become withdrawable after clearing wagering requirements.

How does Freshbet's live event volume compare to Maryland licensed sportsbooks? Freshbet covers 90,000+ live events annually, significantly more than most individual state-licensed sportsbooks. This broader coverage is especially notable for international sports, niche events, and esports markets.
