Casumo has no sister sites. It is operated by Keep Limited, a Maltese company (C91599), and holds licences from the Malta Gaming Authority and the Swedish Gambling Authority. It used to have three sister brands: Dunder and Kazoom have both closed, and CasinoSecret was sold to Breckenridge in February 2023.
🔍 What Happened to Casumo’s Former Sister Sites
Casumo used to run three other brands. None of them is a sister site now.
🎨 Dunder Casino
Closed. Dunder was a Casumo brand through Mill of Magic Ltd, and earlier ran as a white label under MT SecureTrade. The site now serves a closure notice.
⚡ Kazoom Casino
Closed. Casumo launched Kazoom in 2020 as its first Pay N Play brand. It no longer takes players.
💵 CasinoSecret
Still trading, but no longer connected to Casumo. Breckenridge bought it in February 2023, and it now sits alongside Verajohn, Inter Casino and Yuugado.
🕹️ The Casumo Revolution
Swedish founders Oscar Simonsson and Karl Blesgen launched Casumo in 2012 with a radical idea – what if an online casino felt more like a video game? Nobody else was doing it at the time. Players progress through levels, earn belts, collect trophies and unlock achievements, and each milestone pays out on top of the standard bonus offers.
This gamification wasn’t just marketing fluff. The progression system creates goals that keep players engaged between big wins. Earning your next belt or completing a challenge provides satisfaction even on sessions where luck doesn’t cooperate. For players who enjoy RPG elements, Casumo transformed mundane casino play into something more interesting.
The company grew rapidly, eventually amassing over 2,000 games and expanding into sports betting powered by Kambi. Licences in Malta, Sweden, and other regulated markets demonstrate commitment to compliance. The privately-held structure means less public information than listed competitors, but the operation runs professionally.
Casumo’s mascot – a friendly white blob character – became recognisable across gaming forums. Love it or find it childish, the branding differentiated Casumo from the interchangeable casino sites flooding the market. That memorability has value in an industry where switching costs are essentially zero.
🎯 Who Casumo Suits
- 🎮 Gamification lovers – Casumo’s adventure system rewards consistent play with genuine benefits. If you enjoy levelling up in video games, you’ll appreciate this approach.
- 📱 Mobile players – Casumo has native iOS and Android apps rather than a browser wrapper, and they rate well.
- 🎁 One account only – There is no sister brand to claim a second welcome offer at. What Casumo gives is a single offer plus the ongoing level rewards.
🏦 Payments, Support and Sports Coverage
Casumo takes a broad spread of payment methods. Revolut deposits are instant, and PayPal is supported for both directions. Skrill, Neteller and Paysafecard round out the options.
Withdrawal speeds are among the quickest of the Malta-licensed casinos. E-wallet cashouts often clear within hours rather than days. Card withdrawals take longer due to banking processes rather than operator delays. VIP players sometimes receive expedited processing.
Customer support operates 24/7 via live chat. The agents speak English fluently and handle queries competently. Email support exists for complex issues requiring documentation. Chat response times typically stay under five minutes.
Casumo’s sportsbook includes Irish horse racing from all major tracks – Leopardstown, the Curragh, Galway, Punchestown, and Fairyhouse feature with decent odds. GAA coverage exists for intercounty championships. League of Ireland markets appear for bigger fixtures. The sportsbook runs on Kambi, a respected B2B provider that powers multiple operators.

🎰 Games Library
Casumo partners with essentially every major game studio you’d want access to. NetEnt, Microgaming, Play’n GO, Evolution Gaming, Pragmatic Play, Thunderkick, Yggdrasil, and many more contribute to a library exceeding 2,000 titles.
Slot variety covers everything from classic fruit machines to elaborate video slots with multiple bonus features. Megaways mechanics, cluster pays, progressive jackpots – whatever slot style you prefer, it’s represented. Table games include numerous blackjack and roulette variants plus less common options like baccarat and casino poker.
Evolution Gaming powers the live casino section with professional dealers streaming from purpose-built studios. Blackjack, roulette, baccarat, and poker tables run around the clock. Game shows like Crazy Time, Monopoly Live, and Deal or No Deal add entertainment value beyond pure gambling.
🏅 How the Adventure System Works
Casumo’s defining feature deserves detailed explanation. When you play, you earn points that fill a progress bar. Completing a level unlocks rewards – free spins, deposit bonuses, and other prizes. The “belt” system mirrors martial arts progression with coloured ranks from white to black.
Trophies commemorate achievements like first win, biggest win, or playing certain games. These add collectible elements that some players find genuinely compelling. The system transforms random casino sessions into goal-oriented play.
Not everyone appreciates gamification. Some players find it gimmicky or patronising. That is why Casumo kept a plainer sister brand, Dunder, for years. Keep Limited recognises that one approach doesn’t suit everyone.
🏆 Casumo Against Paddy Power and BoyleSports
Casumo is strong on gamification and fast withdrawals. On Irish sport it is beaten by the two Irish books. Paddy Power, headquartered in Dublin under Flutter Entertainment, has deeper GAA coverage. BoyleSports of Dundalk has more League of Ireland markets and remains family-owned.
The differences that matter before you open an account are structural. Casumo is a casino with a Kambi sportsbook bolted on; the other two are sportsbooks that later added a casino, and the weight of the product shows in both directions. Casumo holds Malta and Swedish licences, which is what decides the countries it will accept registrations from, and that list does not match the one Paddy Power or BoyleSports work to.
Bonus structure is the other real split. Casumo spreads its value across the adventure system, paying out free spins and level rewards over weeks of play rather than concentrating everything into one large opening offer. Paddy Power and BoyleSports front-load the welcome offer and attach playthrough conditions to the casino side of it. Neither approach is automatically better: one rewards steady play over time, the other rewards a single sizeable first deposit.
Since Casumo has no sister brands left, there is also no second welcome offer to move on to. Dunder and Kazoom are closed and CasinoSecret belongs to Breckenridge, so the one account is the whole of it. A group like Paddy Power sits inside Flutter alongside other brands, which leaves more room to claim separate offers.
What neither of the Irish books has is the adventure system. If the progression mechanics are what you are there for, Casumo is the only one of the three offering them.
🎲 Final Verdict
Casumo runs on its own now. The three brands it once sat alongside are either closed or sold, so there is no network to move around, and what you are judging is the single site. It is feature-rich, with a progression system and a sportsbook, and withdrawals are quick. For GAA and League of Ireland depth, Paddy Power and BoyleSports remain the better choice. For casino play with a progression system attached, nothing else does the same thing.
