Castle Jackpot Sister Sites 2026

Castle Jackpot has closed as a standalone casino and now redirects visitors to Slot Boss, its closest stablemate on the same LeoVegas Gaming PLC platform. The genuine same-licence sisters still trading in Britain are Slot Boss, Pink Casino, 21.co.uk and Bet UK, all shown in their own footers under UK Gambling Commission account 39198. Royal Panda left the UK in 2020 and Mr Play never sat on the LeoVegas licence at all, so both are covered further down as comparisons rather than as sisters.

Castle Jackpot Quick Verdict

Castle Jackpot Licence Snapshot

What Actually Happened To Castle Jackpot

The shutdown was not announced with much fanfare, so the clearest evidence is the trail the site left behind. Public web archives hold a normal, fully stocked Castle Jackpot homepage as late as 29 November 2021, and the very next captures, from January 2022 onwards, return nothing but a permanent redirect. Every check since then has behaved the same way, which puts the closure at the turn of 2021 into 2022.

Follow that redirect today and you arrive at a Slot Boss page whose browser title still reads “Welcome to Slot Boss | Castle Jackpot Closure”. That is LeoVegas Gaming PLC doing the tidy thing: rather than parking the domain or letting it expire into someone else’s hands, the traffic is pushed to a live brand on the same licence. It also explains why so many older pages elsewhere still list Castle Jackpot as if you could sign up today.

The practical consequence is simple. Any Castle Jackpot bonus code, no-deposit offer or promo page you find in a search result is dead, and any site still promoting one has not rechecked its own content. If you had a balance there, it was a LeoVegas Gaming PLC account, so the operator’s current support desk on any surviving brand is the right place to ask about it.

Castle Jackpot Sister Sites On The Same Licence

Below are the brands worth looking at, split into two groups that most pages blur together. The first group shares Castle Jackpot’s actual operator licence, which is what “sister site” is supposed to mean. The second group is made up of casinos that are frequently listed as Castle Jackpot relatives but sit on a different licence, a different platform or, in a couple of cases, no longer take UK players at all.

Slot Boss

Slot Boss is the brand the redirect chooses for you, so it is the natural first stop. The lobby runs to roughly 600 slots drawn from more than thirty studios, with Nolimit City, Big Time Gaming, Hacksaw Gaming and Play’n GO carrying much of the weight and live tables supplied by Evolution and Pragmatic Play Live. Its current welcome offer is 50 wager-free spins on Big Bass Splash after a deposit of £20 or more and a single one-times playthrough within seven days, with the spins themselves expiring after three days.

What it does not have is a structured loyalty scheme, and live chat is not staffed around the clock, so an overnight query can wait. Deposits and withdrawals cover Visa, Mastercard, Apple Pay and PayPal with no fee at the casino end, and the pending window before a payout is released is typically 24 to 48 hours.

Pink Casino

Pink Casino leans into a girly, glossy theme and backs it up with a genuinely strong rewards scheme, opening new accounts with two separate welcome bonuses before moving on to no-wagering free spins as loyalty kicks in. The slot and live-casino catalogue draws on NetEnt, Microgaming, Evolution Gaming and Betsoft, and support is reachable by email, phone or live chat whenever a hand is needed.

The offer on the front page in July 2026 is 50 wager-free spins for a £10 deposit and a one-times playthrough, which is a lower entry point than Slot Boss asks for. Pink Casino has also become the group’s parking place for retired brands, since both Crown Bingo and Legs 11 now redirect into closure notices hosted on its domain.

21.co.uk Casino

21.co.uk keeps things straightforward with a name that doubles as a nod to blackjack, backed by the same UK Gambling Commission oversight and independent game-testing regime as the rest of the LeoVegas stable. PayPal, Mastercard and Visa cover deposits and withdrawals, and the lobby runs to more than 450 slots alongside a solid spread of table games.

It is the only brand in the group whose headline offer is aimed at the live floor rather than the reels: stake £10 on live casino and you receive £5 in Golden Chips for eligible Playtech tables. If Castle Jackpot’s 25-table live section was the part you used most, this is the closer match of the two big replacements.

Bet UK Casino

Bet UK is one of the leading casinos in the online casino industry. Since then they have modified its website and gaming collection in such a manner that players receive new games and prizes every great month. They are proven safe sites to gamble on as they are licensed and regulated by UK Gambling Commission, with the footer naming LeoVegas Gaming PLC under account 39198 exactly as Slot Boss and Pink Casino do. They have to follow strict guidelines and policies which allow fair gameplay at Bet UK Casino. They have their website compatible for use on mobile phones as well as on PC. Different mobile devices including iOS, Windows, and Android can experience their games on their phones.

The obvious difference from Castle Jackpot is the sportsbook bolted onto the casino, which brings its own separate welcome route. On the casino side the offer is 50 free spins for a £10 deposit with a one-times playthrough; on the sports side it is £40 in free bets after a £10 qualifying bet, with a stated cut-off of 31 July 2026 on the version showing at the time of writing.

Where Castle Jackpot Players Ended Up: A Side-By-Side Check

Every figure here was read off the brand’s own front page and footer in July 2026 rather than lifted from an affiliate listing. Offers move around, so treat the table as a snapshot and confirm on the site before you deposit.

LeoVegas Brands That Have Also Gone Quiet

Castle Jackpot was not the only casualty in this group, which matters because several listings still recycle a much longer sister-site roster than the operator actually runs. Each of the names below was checked by requesting its domain in July 2026 and following wherever it went.

• Crown Bingo – crownbingo.com now lands on a “Crown Bingo is closed” notice hosted on the Pink Casino domain. Our Crown Bingo page covers what it was.
• Legs 11 – legs11.co.uk behaves identically, redirecting into a closure notice on Pink Casino.
• M Casino, Slotto and Slot Mob – mcasino.com, slotto.co.uk and slotmob.com no longer resolve at all.
• Bingo Godz, Bingo Loopy and Bingos – all three former LeoVegas bingo rooms fail to answer.
• Bingo Stars – still trading, but no longer part of this family. The site is live at bingostars.co.uk and its footer now names Solaya Group Limited under account 100050, so it has moved operators entirely. See our Bingo Stars review.
• UK Casino – ukcasino.com is now a casino review and comparison site rather than a LeoVegas casino, despite older register data still tying the name to account 39198.

That is a useful warning about brand registers in general. A licence record can keep a name on file long after the shop front has gone, which is why the domain check matters more than the paperwork.

Royal Panda

Royal Panda is one of the better-known names in the LeoVegas family, built around a panda mascot and a strong live-casino offering alongside its slots. It is no longer an option for British players, however: LeoVegas pulled the brand out of the UK and all activity under its UK licence ceased on 31 January 2020, with Royal Panda Limited’s account 39221 subsequently surrendered.

The international site still exists for other markets under different licensing, so a search result showing Royal Panda as live is not necessarily wrong, just not relevant to a UK account. Anyone who arrived here from an old Castle Jackpot page listing Royal Panda as a sister should treat Slot Boss or 21.co.uk as the realistic swap. Our Royal Panda page keeps the full history.

Frequently Listed But Not A Castle Jackpot Sister

One name appears on almost every Castle Jackpot roundup and does not belong there. It is worth spelling out why, because the distinction changes who you would complain to if something went wrong.

Mr. Play Casino

Mr Play widens the net beyond slots with dedicated bingo rooms and scratch cards sitting next to the usual table game selection. The welcome offer pairs a deposit bonus with wagering-free spins, giving new players a decent head start before they settle into the regular promotions.

It is not, however, a Castle Jackpot sister. Mr Play runs as a white label on AG Communications Limited’s UK Gambling Commission account 39483, a completely separate licensee from LeoVegas Gaming PLC, and that company has been winding down its British white-label business through 2026. Check the site is still accepting UK registrations before you rely on it, and read our AG Communications network guide or the wider casino networks explainer for how white labels differ from owned brands.

Castle Jackpot Review – July 2026

The homepage above is an archived capture of castlejackpot.co.uk from its trading years, kept here because the live domain now shows Slot Boss instead. It is a fair record of what the casino looked like: the gothic wordmark, a hand-drawn castle in the hero banner, a headline offer of up to £100 plus 10 free spins, and a featured-games strip led by Starburst, Legacy of Dead, Book of Dead, Cleopatra and Rainbow Riches.

Castle Jackpot was one of the gaming brands operating under LeoVegas Gaming PLC, established in 2017 and regulated and licensed by the UK Gambling Commission. The site has since closed to new business and now redirects to Slot Boss, so the review below reflects Castle Jackpot as it operated before the switch.

Castle Jackpot hosts various types of games among which there are around 300 featured slot titles such as The Goonies, Starburst, Rainbow Riches, Book of Sphinx, 88 Fortune, Funky Spin, Crown of Egypt, Luck of the Irish, Cats, Ted, Vampire Desire, Treasure of Troy, Safari Gold Megaways, Fruit Snap, Age of Asgard, Eye of Horus and Da Vinci Dual Play. A selection of 9 entertaining table games is waiting for table games fans on Castle Jackpot; for example, there is Players Suite Blackjack, Realistic Roulette, Blackjack Perfect Pairs, and Three Card Poker. Those players who adore live casino games would fall in love with Castle Jackpot collection of live casino games and which displays 25 games among which you can find Live Roulette, Live Speed Roulette, Monopoly Live, Super Sic Bo, Live Baccarat Squeeze, Live Baccarat A and Live Blackjack Party. There is another category of games here which are instant win games like Gem Blast, Ultimate Keno, Grabba Dabba Dough, Deal or No Deal Instant Win, and Scratch 4 Rubies. Bingo devotees can have some fun on Castle jackpot as well, although they have only two bingo games on offerings which are 90 ball and 75 ball bingo games.

Entertainment is surely promised with the Castle Jackpot website as all of their games are provided by reputable and famous software developers essentially Microgaming, Realistic Games, Big Time Gaming, iSoftBet, Evolution, NetEnt, IGT and others. Independent listings that catalogued the site in its final years counted a far larger library once the full back catalogue was included, with more than 1,800 slot titles recorded alongside video poker, keno, hi-lo and scratch cards.

The website of Castle Jackpot was given the theme of a large castle this theme could but give players the impression that they who knights who play to win. No navigation and speed troubles will be encountered on Castle Jackpot site that is amazingly organized to help customers find their favorite games in the blink of an eye.

Once you arrive at Castle Jackpot site you will be welcomed by a big banner that features a 3D old Castle and which informs new players about the welcome offers they get upon signing up on this site. There are actually two welcoming bonuses on this site, the first one is a 100% match bonus on the first deposit and there are wagering requirements for the second offer it is 10 free spins on Book of Dead knowing that new players won’t have to deposit to take advantage of this offer. Existing customers can benefit from a bunch of promotions for instance if you stake £20 on the slot of the week on Castle Jackpot you will earn 10 free spins on the same slot.

The 35x Wagering Figure You Will Still See Quoted

Look closely at the small print under the banner in the screenshot and it sets a 35x wagering requirement on the cash reward. That number is genuine for its time and it is also the reason old Castle Jackpot pages read so strangely now. Britain’s bonus rules changed in January 2026 and capped wagering on UK-facing promotions at 10x, so a 35x offer of that shape simply cannot be advertised to British players today.

If you find a page still quoting 35x, 45x or 60x for Castle Jackpot, it is describing a promotion that ended years before the cap arrived and has not been rechecked since. The surviving LeoVegas brands have moved the other way entirely, with Slot Boss, Pink Casino and Bet UK all running wager-free spins at a 1x qualifying playthrough. Our wagering requirements guide and the 2026 UKGC bonus rules page cover what changed and why.

Banking And Withdrawals As They Stood

Castle Jackpot allows its customers to use no more than 5 banking solutions to make their deposits and withdrawals and which are Visa, MasterCard, SSL Encrypted, Safe and Secure Payments, and the popular iWallet PayPal. Independent reviews of the site recorded a minimum withdrawal in the £10 to £20 range and a 48-hour pending period before a payout was released, after which funds took a further three to five working days to land.

Those timings are worth holding onto because the successor brands have not changed the pattern much. Slot Boss still applies a 24 to 48 hour pending window, with PayPal typically clearing within hours afterwards and card payouts more commonly taking half a day to a full working day. The lesson from both eras is the same: complete identity verification before you request money rather than after.

Trust, Licensing And Player Protection

The reassuring part of a closure like this one is that the operator behind it never went anywhere. LeoVegas Gaming PLC’s UK Gambling Commission account 39198 remains active and is printed in the footer of Slot Boss, Pink Casino, 21.co.uk and Bet UK, alongside a registered office in Sliema, Malta. A player moving from Castle Jackpot to any of those four is staying with the same licensed company rather than starting again with a stranger.

That licence brings the standard British protections: mandatory age and identity verification, deposit limits and time-outs available in the account area, GAMSTOP self-exclusion across every UK-licensed operator, and an alternative dispute resolution route if a complaint stalls. It also means the group’s promotions had to be rebuilt for the January 2026 rules, which is exactly what the shift to wager-free spins reflects.

Independent scrutiny of Castle Jackpot itself was less flattering. Casino Guru scored the site 6.4 out of 10, a rating it labels below average, and the site sat near the bottom of one large review database’s rankings on a player average of around two stars from a small vote count. Neither figure is a scandal, but neither suggests a brand the group was fighting hard to keep.

What Players Actually Said

Player feedback on Castle Jackpot was thin, which is part of the story. A brand with a couple of dozen public votes after several years of trading was never pulling large volume, and low volume is usually what decides which name in a portfolio gets retired.

The complaints that did surface clustered around money leaving the account rather than the games themselves. Slow transfers after a withdrawal was approved came up repeatedly, verification requests on larger cashouts caused friction, and bonus terms were described as tight. On the positive side, the game mix drew consistently fair comment, the castle theme was distinctive in a crowded market, and nobody accused the site of refusing to pay.

Those same themes carry over to the brands still trading, so they are worth planning around. Verification delays and pending periods are the most common gripe across the current LeoVegas line-up, live chat on Slot Boss is not staffed overnight, and there is no structured VIP scheme to fall back on. None of that is unusual for a UK-licensed operator, but it does mean the smart move is to upload documents on day one.

Castle Jackpot FAQs

What are Castle Jackpot’s sister sites?

Castle Jackpot was a LeoVegas Gaming PLC brand, so its sisters are other casinos on the same licence. The ones still trading in Britain are Slot Boss, Pink Casino, 21.co.uk, Bet UK and LeoVegas itself. Slot Boss is the one Castle Jackpot now redirects to.

Who owns Castle Jackpot?

Castle Jackpot was run by LeoVegas Gaming PLC, the same group behind Pink Casino, Slot Boss and several other well-known UK-facing brands. The LeoVegas Gaming PLC operator page lists the wider portfolio.

What licence did Castle Jackpot hold?

Castle Jackpot operated under LeoVegas Gaming PLC’s UK Gambling Commission licence (account 39198). That account is still active today for the group’s surviving brands.

Is Castle Jackpot available to UK players?

No. Castle Jackpot has closed as a standalone site and now redirects to Slot Boss, which remains live and UK-licensed under the same LeoVegas Gaming PLC operator. There is no way to register a new Castle Jackpot account.

When did Castle Jackpot close?

Public archives show a working homepage as late as 29 November 2021 and nothing but a permanent redirect from January 2022 onwards. That places the closure at the turn of 2021 into 2022, and the redirect has been in place continuously ever since.

Is Mr Play a Castle Jackpot sister site?

No, although it is listed as one on plenty of pages. Mr Play runs as a white label on AG Communications Limited’s UK Gambling Commission account 39483, which is a different licensee from LeoVegas Gaming PLC. It is a reasonable alternative to compare, but it is not part of the same family.

Is Royal Panda still open to British players?

No. LeoVegas withdrew Royal Panda from the UK and all activity under its British licence stopped on 31 January 2020, with Royal Panda Limited’s account 39221 later surrendered. The international site serves other markets under separate licensing.

Which Castle Jackpot replacement has the best welcome offer?

It depends on your bankroll and what you play. Pink Casino asks the smallest deposit at £10 for 50 wager-free spins, Slot Boss gives the same 50 spins but wants £20, and 21.co.uk hands out £5 in Golden Chips for a £10 live-casino stake instead of spins.

Can I still claim an old Castle Jackpot bonus code?

No. Every Castle Jackpot promotion ended with the site, and the 35x wagering terms shown in archived screenshots could not be offered to UK players now in any case, because the January 2026 rules cap wagering on UK-facing bonuses at 10x.

Are the LeoVegas brands safe to use?

They hold an active UK Gambling Commission licence under account 39198, which brings verification requirements, deposit limits, GAMSTOP coverage and a dispute route. Player feedback across the group is mixed rather than glowing, with verification and payout timing the most common complaints, so verify your account early.
