Marathonbet Review

Marathonbet has operated since 1997 – nearly three decades of sportsbook heritage – and the operator just pulled off its biggest change yet. A full rebrand to mbet, a completely new platform design, and a revamped bonus structure signal that the veteran operator is serious about competing with modern casino-first platforms.

The mbet Rebrand – What Changed

The old Marathonbet blue-and-white design is gone. In its place sits a modern dark purple interface that looks nothing like the platform most players remember. The navigation now runs across five tabs – Top, Sport, Casino, Live Casino, and Toto – and the overall layout feels faster and cleaner on both desktop and mobile. Panbet Curacao N.V. still runs the operation, but the brand identity has shifted entirely to mbet.

The transition is not fully forced, though. An "Old Website" button in the top-right corner lets players switch back to the classic design. Both versions run simultaneously, which is a practical move for longtime users who are not ready to switch. That said, the new platform is clearly where development is focused – bonuses and promotions are built for the new site first, and some offers only work there.

Licensing – Curaçao GCA, Not the Old Sub-licence

Panbet Curacao N.V. (Company 118257) holds a Curaçao Gaming Authority (CGA) licence under number OGL/2024/648/0172, granted 14 October 2025. This is the reformed licence format that replaced the old 8048/JAZ sub-licence system. Under the 2023–2024 Curaçao overhaul, the GCA introduced stricter oversight, AML requirements, and player protection standards that bring the jurisdiction closer to what MGA operators face.

The practical difference is real. The old sub-licence system had minimal enforcement and loose player protections. The reformed GCA framework requires direct regulatory accountability – operators answer to the authority, not to a master licence holder. For players, this means a measurably better safety net than what Curaçao licences offered before the reform.

4,000+ Games and New Categories

The game library holds 4,000+ titles from providers including Microgaming, NetEnt, Play'n GO, Pragmatic Play, Playson, Quickspin, Yggdrasil, Big Time Gaming, and Spinomenal. The new platform organises games into clear categories: All Games, Favourites, New Games, Popular Games, Jackpot, Bonus Buy, Megaways, Crash Games, and Slots. Seasonal categories like Easter promotions rotate in as well.

The Crash Games category is a notable addition. The old platform did not surface crash titles at all – they were buried or absent. For a dedicated crypto casino with even deeper crash game coverage, see our Stake review. The new design gives them a dedicated tab, reflecting the format's growing popularity. Bonus Buy and Megaways filters are also new, making it easier to find high-variance titles like The Dog House Megaways or Great Rhino Megaways without scrolling through thousands of titles.

300+ Live Tables – Still the Strongest Section

The live casino remains the standout. 300+ games from five providers – Evolution, Ezugi, Pragmatic Play Live, Vivo Gaming, and Live88 – put mbet well ahead of most operators in live dealer depth. Most platforms run 50–150 live games from one or two providers. mbet triples that count.

Live88 adds niche Asian-themed games like Andar Bahar and Teen Patti that are hard to find on European-focused platforms. Players who value live dealer depth specifically can also compare our NetBet review for its Evolution-heavy lobby. Blackjack, roulette, baccarat, poker, and game shows cover the standard selection. For live casino players specifically, the depth here competes with dedicated live casino operators – not just sportsbooks with a live section bolted on.

Welcome Bonus – 500% + 300 Free Spins Across 5 Deposits

The bonus structure has been completely overhauled. The old 100% up to EUR 500 single-deposit offer has been replaced with a multi-deposit welcome package worth 500% + 300 Free Spins spread across five deposits.

The first deposit offers a choice: 100% Bonus in Casino up to EUR 1,000 AND 100 Free Spins on Mummyland Treasures (Belatra), or 100% Bonus in Live Casino up to EUR 1,000. The remaining four deposits fill out the 500% total with additional match bonuses and 200 more free spins.

Critical note: The welcome bonus only works on the new platform (new.marathonbet.com) or the new mobile app. Deposits and play on the old website or old app do not count toward bonus requirements. Players who prefer the old interface should be aware that they will not qualify for any of the new promotional offers.

• Total package: 500% + 300 Free Spins across 5 deposits
• 1st deposit: 100% up to EUR 1,000 + 100 FS (casino) or 100% up to EUR 1,000 (live casino)
• Wagering: 35x – standard for the industry
• Min deposit: EUR 10 – low barrier to entry

Ongoing Promotions – Cashback, Reload, Crypto Start

Beyond the welcome offer, three promotions stand out on the new platform:

Cashback up to 25% – Available in both Casino and Live Casino. The percentage scales with activity, giving regular players a meaningful safety net on losing sessions.

Reload Bonus up to EUR 300 – A recurring deposit match for existing players. This keeps value flowing after the welcome package is cleared.

Crypto Start – 100 Free Spins + a Free Bet for players who make their first deposit using cryptocurrency. This targets the growing crypto player base and stacks with the general welcome package if depositing crypto on the first deposit.

Sportsbook Heritage – The Primary Product

The sportsbook has been the core business for nearly three decades. Deep markets and competitive odds across football, tennis, basketball, ice hockey, MMA, and esports remain the foundation. The new Toto tab adds a pool-betting style product to the mix.

For sports bettors who want casino games on the side – or live dealer tables during halftime – the single-account setup is convenient. A similar hybrid approach comes from Paddy Power, which pairs deep sportsbook markets with a separate casino product. The new design makes switching between sport and casino far smoother than the old interface managed.

Payment Methods – Fast E-Wallets, Crypto Options

mbet covers fiat and crypto in a single cashier. E-wallets are the fastest route – Skrill and Neteller withdrawals clear in minutes to 3 hours, which puts mbet ahead of most operators at this licence tier. The USDT support on both ERC20 and TRC20 adds a blockchain option without forcing players into a full crypto casino. All withdrawals are free, and the EUR 5 minimum deposit is one of the lowest in the industry.

Support and Mobile

Support: Live chat operates from 08:00 to 21:45 GMT daily. Email is available at [email protected] (general) and [email protected] (payment issues). Phone support runs at +44 1273 964706 from 08:00 to 23:30. Not 24/7 – players who encounter issues at midnight will wait until morning.

Mobile: Dedicated apps for iOS and Android are available. The new app matches the redesigned platform and is required for mobile bonus eligibility – the old app does not qualify for new promotions.

Strengths and Weaknesses

Strengths:

• Nearly 30 years of operation (since 1997) – one of the longest track records in the industry
• 500% + 300 Free Spins welcome package – a significant upgrade from the old 100% up to EUR 500 offer
• 4,000+ games with 300+ live casino tables from 5 providers – live casino depth rivals dedicated operators
• Modern platform redesign – the new dark interface is faster, cleaner, and mobile-friendlier than the old design
• 25+ currencies and 20+ languages – one of the broadest global reaches in the industry
• E-wallet withdrawals in minutes to 3 hours – fast by any standard
• Reformed Curaçao GCA licence – stronger regulatory framework than the old 8048/JAZ sub-licence

Weaknesses:

• Dual-platform situation may confuse players – bonuses only work on the new site/app, but the old version is still accessible
• Live chat not 24/7 – limited to 08:00–21:45 GMT
• 15+ providers – smaller provider roster than dedicated casino operators with 80–130 providers
• New platform still maturing – some features and promotions may change as the rebrand settles

Summary

The mbet rebrand is the most significant change in Marathonbet's nearly 30-year history. The new platform looks and feels like a modern casino-sportsbook hybrid – a genuine departure from the functional but dated interface that long-time players know. The 500% + 300 Free Spins welcome package, 25% cashback, and Crypto Start promo give the promotional lineup real depth.

The 300+ live tables from five providers remain the casino's strongest asset – few operators match that live dealer range. The reformed Curaçao GCA licence provides a better regulatory foundation than what the operator had under the old sub-licence system. E-wallet payouts still clear in minutes to 3 hours, and the 25+ currency support keeps mbet among the most globally accessible platforms.

The main friction point is the dual-platform transition. Bonuses only work on the new site and new app, which means players need to be on the right version before depositing. Once that settles – and the old interface is eventually retired – the rebrand positions mbet to compete more directly with modern casino-first operators.
