Casino sister sites for UK players: which casinos share an owner

Two casinos are sisters when one company runs both, or when one parent group owns the companies behind them.

Featured casino sister sites

Seven casinos have a page here, and each card shows its licence holder, its rating and the number of sisters we review, with MrQ the one casino that has no sister site. Before a page is published, our team tests the casinos and checks every fact on it.

What sister sites are, and sites like a casino

A sister site is a casino run by the same company, or by a company in the same parent group, as the one you already play at. Octomark uses two kinds and no others: same company and licence, or same parent group on separate licences. A shared games supplier, a shared payment page, a shared address or a lookalike design does not make two casinos sisters, and we treat none of those as evidence. Both kinds are named in plain words wherever a casino is listed, so you can tell a company link from a group link.

What it means for you is narrower than it sounds. Sister sites share an owner, not a promise: each sets its own terms, its own payout wording and its own offer, and the figures often differ inside one family. What does travel is account control. Most casinos here allow one account per brand only, and several apply a self-exclusion across every account on the same licence. Check the sister's own terms before you open an account, because the company behind it can be the same while the rules on your money are not. A site like a casino is a different thing again, and we never call one a sister: when a casino has no sisters, its page lists other casinos we review that meet a rule printed on the page, and that rule is the only claim being made.

Why map owners at all? Because three things tend to move together inside a family: the complaints route, the reach of a self-exclusion and often the payout wording. When you know which casinos share a company, you know whose terms to read first and which of your accounts one decision can touch. It does not tell you which casino is better, and a family is not a ranking.

How we decide two casinos are sisters

We start with the operator line each casino prints about itself. 32Red and Unibet both name Platinum Gaming Limited in their terms, and Dream Jackpot and 666 Casino both name Jupiter Gaming Limited. We then read the Gambling Commission public register for that company: the business detail page and the websites listed under its account, read on 27 September 2026 for most of the accounts here.

A parent group needs its own evidence. We take a parent only from the casino's own terms, the parent's own brand list or a register record, never from an affiliate site or a shared platform. That is why 888 Casino and William Hill are group sisters on separate licences: 888 Casino's user agreement and William Hill's help pages both name evoke plc, and evoke's brand page lists both.

Two limits apply. The register shows what it lists on the day we read it, so each page states its read date. Some casinos print no parent at all, among them MrQ, Dream Jackpot and Spin Genie, so we write none rather than fill the gap. Send us any company link we have missed, with the page where you saw it. The method page sets out every step.

The casino families we cover

Each row is one licence account as the Gambling Commission register lists it, and we count only websites the register marks active. The table gives the company, its parent group where a source names one, and the casinos we review on that account. Read it as a map, not a ranking: a casino in a large family is neither better nor worse for it.

Videoslots LimitedNot statedMr Vegas, Mega Riches and Videoslots

Skill On Net Limited holds the largest account here, with Spin Genie, PlayOJO and Mega Casino reviewed on it. The register lists dozens of other brands under the same licence, from white label bingo rooms to casinos with their own domains, which we do not review. Platinum Gaming Limited and Jupiter Gaming Limited also have further domains on their accounts that we do not review.

William Hill sits on its own account, held by WHG (International) Limited, under the same parent as 888 Casino, evoke plc, so it is a group sister on a separate licence, not a licence sister.

Where a family sits on a single account, the register is the cheapest check you can make for yourself: search the licensee name on the Gambling Commission public register and compare the websites it lists with the casinos in the table.

Family by family

Each family below opens with the company on the licence, then gives the ratings, offers, payout wording, games, loyalty scheme and complaints service of its casinos. Each family links to its page for the full comparison.

MrQ: Tek Fox Ltd

MrQ stands alone, and it rates 3.9. Tek Fox Ltd runs it, the register lists a single website under the account, and there is no sister to set beside it. The welcome offer is free spins on Big Bass Splash with no wagering on the winnings and a 10p maximum stake per spin. Withdrawals are stated as processed instantly in most cases, with longer when checks are needed. It claims 900+ games, a smaller catalogue than most here, and no loyalty scheme appears anywhere on its site, so a regular player earns nothing back on a stake. Support is live chat and email, with chat staffed every day of the week. Complaints it cannot settle go to IBAS. Its page lists alternatives instead of sisters, under a rule printed on it. Ask support for anything in writing that its pages do not say, and keep the reply.

32Red and Unibet: Platinum Gaming Limited

32Red and Unibet are the same company and licence, and the ratings are close: 4.5 for 32Red, 4.7 for Unibet. Both run free spins on a first deposit and both apply the same multiplier to what those spins win, so this family is consistent in a way others are not. 32Red claims 2,000+ casino games, while Unibet publishes no game count at all, so we leave it unscored on games rather than guess. Each runs a three tier rewards scheme you can join only by invitation, Ruby Lounge at 32Red and Reward Zone at Unibet, and each names eCogra for disputes it cannot settle. 32Red holds a withdrawal pending for at least a day before processing it, and Unibet states no pending period, so we could not confirm one. On support, 32Red lists live chat with a typical response of up to 24 hours, and Unibet lists live chat and email. Compare both sets of terms side by side before you open the second account, because one company does not mean one rulebook.

Dream Jackpot and 666 Casino: Jupiter Gaming Limited

Dream Jackpot and 666 Casino are the same company and licence, and both reach 5.0 on four of the six criteria we score. The pair is almost identical on paper: the same offer shape with no wagering on the spins winnings, the same minimum deposit and withdrawal, live chat around the clock, and IBAS named for a complaint neither can settle. Both list apps for iPhone and Android, and the deposit methods differ only at the edges: Dream Jackpot adds PayPal and Trustly, while 666 Casino adds bank transfer. The gaps match too. Neither states a payout time anywhere we could read, neither publishes a game count, and neither has a rewards page we could open, so two criteria stay unscored at each. That makes the rating a statement about stated terms, not about speed. Ask either one in writing how long a withdrawal takes before you deposit, because nothing on either site commits to a figure.

Spin Genie, PlayOJO and Mega Casino: Skill On Net Limited

Spin Genie, PlayOJO and Mega Casino share one company and one licence, and they sit within a fraction of each other: 4.6 for Spin Genie, 4.6 for PlayOJO, 4.4 for Mega Casino. The welcome offers differ. Spin Genie gives 120 free spins on Book of Dead for a first deposit of £10 or more, with 10x wagering on the spin winnings. PlayOJO gives 50 free spins on Big Bass Bonanza and states no wagering requirements. Mega Casino gives a 100% match up to £25 plus 50 free spins, with 10x on both the bonus and the spin winnings, so check that wagering figure before you deposit at Spin Genie or Mega Casino. The catalogues are where they part next. PlayOJO claims 8,000+ games, Mega Casino 5,000+ and Spin Genie 4,000+, each the casino's own claim with no exact count behind it. Payout wording parts them further: PlayOJO states that 95% of withdrawals are processed within minutes, Spin Genie states within 24 hours, and Mega Casino states 1-3 business days for card withdrawals, up to 5 depending on the bank, the slowest stated route in the family. Loyalty differs as well: Spin Genie has My Levels, PlayOJO has OJOplus, and Mega Casino has a Mega VIP Casino Club that is by invitation only. Spin Genie and PlayOJO name eCogra for unresolved disputes, while Mega Casino names no outside service on the pages we read, which leaves you with its own process and nothing after it. On support, Spin Genie and Mega Casino state live chat from 06:00 to 00:00 GMT, while PlayOJO states round-the-clock help. Check which of the three you are on before you ask about a withdrawal, because a shared licence does not mean a shared speed.

888 Casino, 777 and William Hill: evoke plc group

888 Casino and 777 sit on one company and licence, and William Hill is run by another company on its own licence, with evoke plc the parent of all three. 888 Casino rates 4.4, William Hill 4.4 and 777 3.6. The offers separate them. 888 Casino and William Hill both ask ten times the credited amount, while 777 asks 35x, the heaviest multiplier we found anywhere on this page, and all three cap what you can withdraw from the offer. 888 Casino claims 2,000+ games and 777 claims 800+, the smallest figure in this family. Payout wording is thinner: 888 Casino states no withdrawal time that we could confirm, 777 states three business days from the date of request, and William Hill states 1 working day for PayPal and Skrill and 1 to 3 working days for most cards. Until 888 Casino's support confirms a timescale, do not plan around one. All three run a points to cash scheme and all three state identity checks before a withdrawal. 888 Casino and 777 name eCogra for a complaint they cannot settle, and William Hill names IBAS. William Hill lists apps on the App Store and Google Play, while 888 Casino and 777 offer play in the browser or by download, and we found no store app for either. Check the multiplier on the sister before you move a balance across, because the companies are linked and the terms are not.

Mr Vegas, Mega Riches and Videoslots: Videoslots Limited

Mr Vegas, Mega Riches and Videoslots are one company and one licence, and the ratings barely move: 4.4 for Mr Vegas, 4.3 for Mega Riches, 4.3 for Videoslots. The catalogues are the widest here by the casinos' own counting, 12,000+ at Videoslots, 10,150+ at Mr Vegas and 8,000+ at Mega Riches, though none of the three publishes an exact count. The welcome terms share one shape across all three: a spins part with no wagering on the winnings, and a matched part with a multiplier on it. All three state that withdrawals are processed within 48 hours once checks are done, and all three send a dispute they cannot settle to IBAS. Mega Riches and Videoslots both promise an answer within 24 hours, and Mr Vegas states round-the-clock live chat. None of the three lists a loyalty scheme, so there is no earn back here for a regular player. Keep a note of your last login if you plan a long break, because an idle account can cost you a monthly fee at two of them.

What follows you between sister sites

Protection comes first here, so start with self-exclusion, because its reach is not the same at every casino in a family. MrQ says a self-exclusion covers your MrQ account and any website it runs in future. PlayOJO applies yours automatically to other casino accounts on the same licence, and Spin Genie does the same for any other account it knows you hold on that licence. Those are licence wide, not brand only.

Two groups go wider than one licence. 32Red's help pages say a self exclusion there also covers every UK brand run by FDJ UNITED, and they name Unibet and Bingo.com. 888 Casino extends any new self-exclusion request to the related accounts it identifies across the 888 and William Hill group brands, and it names William Hill. Dream Jackpot, 666 Casino, Mega Riches and Videoslots state no such scope, so we could not confirm that an exclusion at one reaches the others. Ask each casino in writing how far its exclusion reaches before you rely on it.

Where a casino's own clause stops, the national scheme does not. One request to Gamstop Online blocks you from gambling websites and apps licensed in Great Britain, which covers every casino named here. A sister site is never a way around a self-exclusion, and none of these casinos presents it as one. Register with Gamstop Online if you want the block to hold on every licensed site, not just one company's brands, and tell any casino where you still hold an account.

Two account rules travel with you as well. Dream Jackpot and 666 Casino each allow one account per brand. PlayOJO is stricter: one account per person, household, family, address, email, card, e-wallet or shared computer, such as a library or workplace. Dormant accounts cost money at most of these brands: 32Red and Unibet each deduct £5 a month, 888 Casino, 777 and William Hill each take £3 a month, and MrQ states it does not apply any inactive or dormancy fees. Close an account you no longer want rather than leaving it idle, and tell the casino in writing when you do.

To find a casino's own scope, open its responsible gambling or terms page and look for the self-exclusion clause. Where the clause names other brands, those are covered. Where it says nothing, ask support in writing, and treat silence as no promise. Do this before you open a second account in a family, not after.

Comparing welcome offers inside a family

Two words decide what an offer is worth: wagering on winnings, or wagering on the bonus. Wagering on winnings means only what the free spins pay out has to be staked again before you can withdraw it. Wagering on the bonus means the whole credited amount has to be staked, usually several times over, and the figure is a multiplier of that amount. One family often uses both shapes, so read the line under the headline rather than the headline itself.

No wagering on the spins winnings is the shape at MrQ, Dream Jackpot, 666 Casino and PlayOJO. PlayOJO goes furthest: its stated figure is 0 on the whole bonus, not only on the spins winnings. A zero figure still has conditions attached: Dream Jackpot and 666 Casino each want a £20 deposit staked before the spins arrive, MrQ wants £10 of play, and every one of them runs its identity checks before a payout reaches you. Check each condition before you deposit.

The rest attach a multiplier to the credited amount. Ten times is the common figure, at 32Red, Unibet, Spin Genie, Mega Casino, 888 Casino, William Hill, Mr Vegas, Mega Riches and Videoslots. First deposits vary more than the multiplier does: £10 at most of them, and £30 at 32Red and Unibet before any spins arrive. 777 is the outlier at 35x, so a £10 match needs £350 staked before anything is withdrawable, and its terms cap the payout from that offer at £100. William Hill holds its own cap to £30. Work out the stake a multiplier implies before you deposit, and walk away from a figure you would not have staked anyway.

Stake limits and time windows matter as much as the multiplier. While bonus funds are in play, 32Red and Unibet cap a bet at £15 per spin on slots, Mr Vegas and Videoslots at up to £20 and Mega Riches at £2, so a stake above the cap can put the bonus at risk. The clock is tight too: 32Red gives you 48 hours to claim its spins, Unibet and MrQ 48 hours to use theirs, and 888 Casino 90 days to clear its bonus. Find the cap and the deadline in the small print, and set a reminder for the day your offer lapses.

Which games count is the last check. Unibet counts table games at 10% against 100% for slots, and Spin Genie and Mega Casino count slots only. Play the games that count, or the wagering will not move.

When a casino has no sister sites

One casino on this page has no sister sites: MrQ. The register lists one website under its account and no other brand, so there is no sister to review. Read the MrQ page for the full evidence.

Instead of sisters, such a page lists alternatives, picked by a rule printed on the page. For MrQ the rule is the other casinos we review whose welcome offer, like MrQ's, has no wagering. We always call them alternatives and never sisters, because the register ties none of them to the casino. Treat the printed rule as the whole claim, and read each alternative's own terms before you act on it.

A page like this has the same headings as every other page on the site, so you can compare it with a sister page section by section. Every other casino here has at least one reviewed sister, so this applies to MrQ alone. If the register later lists a second brand under the account, the page changes to the ordinary sister format.

Why it matters: with no sisters, there is no second casino of the same company to compare terms with, so check MrQ's own terms for what a self-exclusion, the one-account rule and a complaint mean at that one casino.

How we rate the casinos

Our team tests every casino here and checks every fact before a page is published. The rating is a weighted score: bonuses carry 20 of the weight, games 20, account and safety 15, loyalty 10, support 10 and mobile 5, which is 80 in total. Payments and speed is shown on every page but carries 0, so it is not scored. The method page sets out what each criterion rests on, step by step.

By family, the ratings are: MrQ 3.9; 32Red 4.5 and Unibet 4.7; Dream Jackpot 5.0 and 666 Casino 5.0; Spin Genie 4.6, PlayOJO 4.6 and Mega Casino 4.4; 888 Casino 4.4, 777 3.6 and William Hill 4.4; Mr Vegas 4.4, Mega Riches 4.3 and Videoslots 4.3.

Where a casino states no figure for a criterion, we leave it unscored and say so on its page. Unibet is unscored on games because it states no game count, and Dream Jackpot and 666 Casino are unscored on games and loyalty, the second because we could not read their rewards pages. A high score therefore says a casino states a great deal clearly, not that it pays quickly, so check the payout wording on its page before you choose. A finding that costs you money lowers a score, and a commercial arrangement never raises one.

Octomark reads and quotes the Gambling Commission public register for every account named here, and reads each casino's own terms, help pages and offer pages for the figures. What the site is and who runs it sits on the about page.

Complaints and disputes

Every casino's first step is its own complaints process, in writing, and the outside service comes second. If its answer does not settle it, after 8 weeks you can take the complaint to the service it names, which is free. The Gambling Commission does not resolve or make decisions on complaints regarding gambling-related transactions, so do not wait on it. Complain to the casino first, keep dates, reference numbers and screenshots, then go to the service named below.

eCogra is the named service at 32Red, Unibet, Spin Genie, PlayOJO, 888 Casino and 777. 32Red and Unibet point disputes to it in their terms. Spin Genie and PlayOJO give a supervisor 96 hours to come back with a decision, and 888 Casino and 777 route an escalation to a second opinion team first.

IBAS, the Independent Betting Adjudication Service, is the named service at MrQ, Dream Jackpot, 666 Casino, William Hill, Mr Vegas, Mega Riches and Videoslots. MrQ aims to acknowledge a complaint within 24 hours. Dream Jackpot and 666 Casino answer within 3 working days and escalate to a manager within 10. William Hill routes an escalation to a second opinion team first, and Videoslots, Mega Riches and Mr Vegas ask you to come forward no later than 6 months after the event.

Mega Casino is the exception, with no named outside service in our reading. Put the question to its support in writing, asking which service handles an unresolved dispute, before you need one.

What we leave out

We leave out any website the register marks inactive, and there are plenty. Jupiter Gaming's account lists 10 websites and shows 7 active. The 888 UK account lists 90 and shows 16. Skill On Net's lists 61 and shows 59, and Videoslots' lists 5 and shows 4. A dead domain is not a sister site, so we neither count it nor name it.

Every licence account named here shows as active on the register, and we leave out any casino whose licence it no longer shows as active.

Two casinos are held back rather than published. Winomania has a register lead only and its research pack holds no facts, so it has no page. 7Bet waits on its family, because none of the 7 white-label Anakatech domains nor LuckyMate is researched yet. Neither hold is a judgement on the casino. Check back here before you decide on either.

A casino missing from this page has not been researched here, and that says nothing about whether it is safe.

Gambling help for UK players

Help comes first, and none of it runs through a casino. The National Gambling Helpline is on 0808 8020 133 for England and Scotland, and the NHS Wales Helpline is on 0808 2819 265 for Wales. GambleAware states that these support services are available only to Great Britain residents, and no helpline for Northern Ireland appeared on the pages we read, so we name none. Ask your GP about local support if you live in Northern Ireland. Gambling is for adults: you must be 18 or over to hold an account at any casino named here.

Every casino here states tools you can use long before you need a helpline, including deposit limits, time outs, reality checks and self-exclusion, all set from your own account. A sister site is never a way around a self-exclusion. Set a deposit limit on the day you open an account, not the day you start to worry, and use our responsible gambling page for what each casino states and where to find support.

Gamstop and GambleAware both run their own help pages, and neither belongs to a casino. The links below open them. A casino's own support can often help you set a limit or a time out, but it is a first step, not a replacement for those services.

Questions about casino sister sites

What is a casino sister site?

One that shares an owner with another casino, whether through a single operating company or through a parent that owns several. The link tells you who runs the brand, nothing more: it does not tell you which casino is better.

How does Octomark know two casinos share an owner?

By cross-reading two public sources. A casino's own terms name the company behind it, and the Gambling Commission register shows what else is listed under that company's account. A claimed parent group needs a further document, such as the parent's own brand list.

Is a sister site the same as a site like a casino?

No. A sister shares an owner. A site like a casino is picked by a rule we print on the page, such as a welcome offer with no wagering, and nothing ties it to the casino you searched for. We never use the word sister for one, because no register entry supports it.

If I self-exclude at one casino, am I excluded from its sister sites?

It depends on that casino's own clause. MrQ, PlayOJO and Spin Genie extend an exclusion beyond one site, and 32Red reaches its group's UK brands. Several others state nothing at all, so we could not confirm it. Ask the casino in writing before you rely on it. Gamstop Online is the route that covers all licensed sites at once, whoever owns them.

Can I claim a welcome offer at each sister site?

Usually yes, because each brand runs its own offer and most of these casinos allow one account per brand. Read the qualifying stake and the wagering line at each one before you deposit. They are set separately, and a single family runs anything from no wagering at all to a 35x multiplier.

Do sister sites pay out at the same speed?

Not reliably, and a shared licence is no guide. Inside the Skill On Net family the stated speeds run from minutes to several business days. Three casinos here, Dream Jackpot, 666 Casino and Unibet, state no payout time anywhere we could read, so we could not confirm one for them. Compare the stated time on each casino's own page, not the family's.

Which sister sites have no wagering on the welcome offer?

Four of them: MrQ, Dream Jackpot, 666 Casino and PlayOJO. Their stated figure is zero on what the free spins pay. Everywhere else a multiplier applies to the credited amount, usually ten times, and 777 sets the heaviest figure. Check the qualifying stake and time window before you claim, because a zero figure still comes with both.

What if a casino has no sister sites?

Then the page says so and shows the evidence: the register's single entry and the casino's own operator line. MrQ is the only such casino here. It gets a list of alternatives chosen by a printed rule, and none of them is called a sister.

How does Octomark rate the casinos?

Six criteria are scored, each with a fixed weight, and bonuses and games weigh most. Payments and speed is displayed without a score. We test each casino and check every fact before a rating goes live. Any criterion a casino gives us nothing for stays blank and is named on the page. Read the rating note on a casino's page to see which criterion is blank.

Where can UK players get help with gambling?

Call the National Gambling Helpline on 0808 8020 133 if you are in England or Scotland, or the NHS Wales Helpline on 0808 2819 265 in Wales. GambleAware publishes both numbers. Your casino's own limits and time out tools are set from inside your account, whenever you want them.
