Duelz Casino Sister Sites

Short answer: yes, Duelz has sister sites — three of them — and the company behind it is not the one most affiliate lists name. Duelz is run by SuprPlay Limited, a Malta-based operator licensed by the UK Gambling Commission under account 48695. Three more UK casinos sit on that same licence — VoodooDreams, NYSpins and Los Vegas — and those are Duelz's genuine sisters. If you have read that Duelz belongs to SkillOnNet, alongside PlayOJO or SlotsMagic, that is wrong, and the register settles it in about a minute.

Who actually runs Duelz

The company on the hook for Duelz is SuprPlay Limited, registered in Malta and holding a UK remote casino licence granted on 27 September 2017. You can read the entry yourself on the Gambling Commission's public register under account 48695; at the time of writing it shows an active licence and no recorded regulatory action. One word of warning: the licence carries a longer reference number that the Commission reissues as licences are amended, so the six-digit account — 48695 — is the stable thing to search on. Don't treat a specific full-reference string copied from an affiliate page as fact, including from an earlier version of this one.

SuprPlay is the UK licence-holder inside the SuprNation group, the operator that built Duelz, VoodooDreams and NYSpins. In November 2023 SuprNation was acquired by DoubleDown Interactive for roughly $36.5m, a firm previously known for social-casino games moving into real-money gaming. So the ultimate owner today is DoubleDown rather than an independent Maltese founder team — but the UK licence still sits with SuprPlay Limited, and that is the name to quote in any complaint or query.

Duelz's sister sites

Two casinos are sisters, in the only sense that protects your money, when they share the same operating licence — not when they merely share a look, a game studio or a payment logo. By that test Duelz has exactly three, all on SuprPlay's account 48695:

Here is the quirk that hides them. Most operators register their casinos with the Commission as trading names, so one search shows the whole family at a glance. SuprPlay records no trading names at all — its four brands appear only as domain names, each marked active: duelz.com, voodoodreams.com, nyspins.com and losvegas.bet. A writer who checks only the trading-names field finds nothing and calls Duelz a one-brand operator. The sisters were on the register the whole time, just in the column nobody thought to read. You can see them for yourself on the domain-names page of the same entry.

So why do so many lists say SkillOnNet?

Because Duelz looks the part — a clean, Nordic-styled product with a game grid pulled from the same small pool of studios most UK casinos use — and because copying the previous list is easier than reading a register. SkillOnNet, properly Skill On Net Ltd, is a different company on a different licence (account 39326) and really does run PlayOJO and SlotsMagic. Duelz is not among them. The mistake isn't harmless: a deposit limit or self-exclusion you set with SkillOnNet does nothing at Duelz, because it is a separate operator with a separate account, separate customer funds and a separate complaints desk. Aim a Duelz complaint at SkillOnNet and it lands on the wrong company's desk.

What sharing a licence does — and doesn't — change for you

Knowing the real family matters because it decides what your own safer-gambling controls actually reach:

• Self-exclusion set with SuprPlay is designed to close its brands together, so stopping at Duelz should also shut VoodooDreams, NYSpins and Los Vegas.
• Deposit limits are less dependable across a family — they often bind only the account they were set on — so set one afresh at each brand you open rather than trusting a single figure to cover all four.
• Identity checks are generally completed once and recognised across the operator, which is why a second brand in the same house can feel quicker to join.
• A welcome offer is normally once per operator, not once per brand, so opening a sister to claim “another” bonus usually won't work.

For a limit that reaches every UK-licensed site at once rather than one operator's four brands, the tool built for that is the national online self-exclusion scheme — a single, free registration that works independently of any casino.

What could change this line-up

Ownership is never permanent, so this page is accurate on the date you read it rather than for ever. Three things would move it, and each is a discrete event you can check. A new brand on account 48695 — appearing as another active domain, or as a trading name, with its own terms naming SuprPlay — adds a sister the day the register lists it. A brand dropping off the licence removes one, often with nothing visible changing on the casino itself. And a licence transfer, with Duelz moving to a different operating company, would replace this whole family with whoever sits on the new licence — new terms and possibly fresh checks included. Each shows up on the register before it shows up on an affiliate list.

What to check before you play

• Find the operator in the small print. Duelz's own terms name SuprPlay Limited. If a casino's footer names a company you can't find on the register, treat that as a reason to stop, not proceed.
• Search the account, not a string. Look up 48695 on the register and confirm the licence is active before you deposit.
• Read the domains, not just the trading names. That is where SuprPlay's family lives — and the habit will save you on other operators, too.
• Write down the date you checked. Ownership is a snapshot; licences transfer and brands leave, so a claim with no date can't be judged.

The verdict

Duelz is a straightforward one to place: a real, long-standing UK-licensed casino run by SuprPlay Limited, now under DoubleDown Interactive, with three verifiable sisters in VoodooDreams, NYSpins and Los Vegas. The only real trap is the paperwork — the SkillOnNet label that was never true, and three sisters tucked away in the domains column. Just remember that licensed is not the same as risk-free: a licence makes the operator accountable, it doesn't make your stake safe, and the games can still lose.
