Important licensing note
SpinKong’s own pages claim no licence at all: no operator name, no licence number, no company address, no regulator’s seal, anywhere on the site. The network it belongs to does hold a current licence, an open-ended Curaçao Gaming Authority permit, reference OGL/2023/176/0095, issued to Hollycorn N.V., and sister brands like Plan Games display that reference. SpinKong just never says so, and its terms restrict players from forty territories, Curaçao itself among them, while the United Kingdom is never mentioned.
A Curaçao licence is legitimate, but it isn’t a UK one, and that gap is the entire problem for British players. UK visitors are served freely, in pounds, with no UK Gambling Commission licence behind the site: no GAMSTOP self-exclusion, no affordability or safer gambling checks, no independent dispute route, and no protection of any kind for deposited funds.

The Hollycorn N.V. network runs to dozens of casino and betting brands on one shared platform, cashier and licence, and the five sister sites below are the ones a SpinKong player is most likely to meet, whether in search results or in the network’s own cross-promotion.
Queenwin Casino
- The sister that left Britain: Britain’s regulator forced Queenwin Casino out of the UK market in March 2025 for trading without a licence, an action its gorilla-fronted sister site has so far avoided attracting.
- Crowns run in the family: Its monarchy branding comes with a graffiti twist, and SpinKong’s own mascot wears a crown too; royalty is clearly a theme this operator keeps returning to.
- The weekend beat the welcome: Its best offer at its UK-facing peak was a Saturday reload at just 10x wagering, a better deal than anything on SpinKong’s 30x-to-45x menu.
- A thinner games selection: Its lobby is one of the network’s smallest, leaning on the same little-known studios SpinKong stocks rather than household slot names.
- A payout record to weigh: Player feedback on Queenwin Casino is dominated by accounts frozen at the point of withdrawal, the single most serious complaint a casino can attract.
BetnJet
- SpinKong, rebadged: BetnJet’s promotions page lists the same 400% up to £1,000 package, the same 120%, 130% and 150% deposit tiers and the same £150 first-week cashback as SpinKong, with the jungle names swapped for jet-set ones.
- The other one still serving Britain: Of all the sister sites checked for this review, BetnJet is the only other brand that still loads for UK visitors rather than turning them away.
- A 2025 arrival: It launched in 2025, one of the newest names on the network, and its promotions lean towards new sign-ups over returning players.
- Predictions on the side: Its menu carries a Predictions game alongside the sportsbook, a feature SpinKong doesn’t offer.
- Built for the flying visit: The bet-and-jet branding is aimed at players who want a quick session rather than a long loyalty scheme, the opposite pitch to SpinKong’s eleven-rank Royal Club.
Stay Casino
- The network’s benchmark: Live since 2021, Stay Casino is one of the family’s most established brands, and the measuring stick the newer arrivals get judged against.
- The deepest library in the family: Its game catalogue is the fullest on the network by some distance, where SpinKong leads with a narrower wall of lesser-known studios.
- Cashback lands on Mondays: Its signature deal returns a share of weekend losses every Monday, a standing arrangement SpinKong only matches once you’ve climbed to the Royal Club’s fifth rank.
- Britain gets a flat refusal: UK visitors are met with an Access Denied message rather than a homepage, so this one is sealed off from British players entirely.
- A fuller welcome package: Its multi-stage welcome package stretches across more early deposits than most of its sister sites offer.
Casino Rocket
- The 2020 veteran: Casino Rocket has been online since 2020, one of the network’s longest-serving brands and an early adopter of crypto banking before that was standard practice.
- A theme worn properly: Its outer-space identity runs right through the promotions rather than stopping at the banner, the same commitment SpinKong shows to its jungle royalty.
- A hard no to Britain: UK visitors are sent straight to a Forbidden page, an outright block where SpinKong rolls out a welcome banner instead.
- Something always running: A rolling set of daily offers keeps its promotions calendar busier than most SpinKong sister sites manage.
- Read before you opt in: Its bonus wagering isn’t always the friendliest on the network, so the terms deserve a close look before you take any offer.
Plan Games
- The one that shows its paperwork: Plan Games displays the network’s Curaçao licence reference, OGL/2023/176/0095, on its own pages, the disclosure SpinKong never makes anywhere on its site.
- A 2024 addition: It was established in 2024, part of the operator’s recent run of launches rather than its founding generation.
- Plain name, plain dress: It’s one of the network’s least theatrical brands, the opposite approach to a casino fronted by a gorilla in black tie.
- Closed to British visitors: UK traffic lands on a holding page rather than the casino itself, so it belongs with the blocked majority of this family.
- Best use: The reference point that proves who runs this family, even when the family’s other brands won’t say.
How this review was made
Every claim here comes from a source I can point you at, so you can judge the page on its evidence. My full approach is on the About Us page.
Rob Hill
Desk researched from a UK connection. The SpinKong site was read in full: homepage, general terms, the complete bonus terms, privacy policy, About, payments, FAQ and Royal Club pages. The sister sites named here were each visited the same day, and the blocks recorded are what a UK visitor is actually shown. No account opened, no deposit or withdrawal made.

None. SpinKong holds no UK Gambling Commission licence. The similarly named Spin King is a different, unrelated casino with its own UK licence.
The SpinKong site in full; the Curaçao Gaming Authority’s online gaming licence register, 14 August 2026 edition; the UK Gambling Commission public register; the homepages of BetnJet, Stay Casino, Casino Rocket, Queenwin Casino and Plan Games as served to a UK visitor; this site’s Queenwin Casino review; a UK search sweep of the brand’s marketing footprint.
18 August 2026, first published version
A gorilla in a crown, and a very familiar menu
The theme is King Kong with the serial numbers filed off. The name never appears, but the mascot is a giant gorilla in a crown and dinner jacket, cocktail in hand, presiding over a jackpot machine, and the branding leans into it everywhere: promotions called Kong’s Lucky Seven, Kong’s Golden Streak and Kong’s Daily Boost, and a loyalty scheme whose eleven ranks climb from Kong Member through the Ace tiers to Kong Elite, Kong Crown and finally SpinKong itself. That top rank asks for 80,000 status points, and at one point per £50 wagered on slots, that’s £4 million of play. The games behind the branding come from BGaming, Booongo, Netgame, Popiplay, Belatra and similar studios, legitimate but little-known names, without the headline providers a UK-licensed lobby would lead with, and a sportsbook sits alongside the casino with odds on the Bundesliga and other major football.
Set the theme aside, though, and the menu underneath belongs to the network, not the brand. BetnJet, its still-UK-facing sister site, advertises the same 400% up to £1,000 welcome package, the same three deposit tiers at 120%, 130% and 150%, the same paired high-roller offers, the same first-week free-spins missions and the same 10% cashback capped at £150, all to the pound, under different names. SpinKong’s contribution to the formula is the gorilla; the rest is shared infrastructure.
Ownership: the operator that never signs its name
Ask SpinKong who runs it and the site simply doesn’t answer. The general terms run through deposits, withdrawals and fraud rules without ever naming a company, a licence or an address; the privacy policy speaks of “the Company” and “our group of companies” without identifying either; the About page signs off with nothing but support@spinkong.com. That silence isn’t sloppiness; it’s the network’s current house style, and the paper trail cuts through it anyway. SpinKong’s terms are the same document BetnJet publishes, matching version number for version number and country for country down to a shared clause banning replaceable Bitcoin transactions, and through this we know the operator: Hollycorn N.V., a Curaçao company registered at Heelsumstraat 51, E-Commerce Park, Willemstad, whose licence reference appears on another SpinKong sister site, Plan Games.
That licence is valid and current. The Curaçao Gaming Authority’s register, in its 14 August 2026 edition, lists Hollycorn N.V. as holder of business-to-consumer licence OGL/2023/176/0095, granted under the island’s new gaming regime with no expiry date. What the licence record can’t explain is the network’s split personality over Britain. Queenwin Casino was blocked from the UK market in March 2025; Stay Casino, Casino Rocket and Plan Games all turn UK visitors away at their own front pages. SpinKong does the opposite: it serves Britain a specific homepage, prices its entire bonus programme in pounds, and leaves the United Kingdom off a restricted-country list that manages to bar forty territories including Curaçao itself. One operator, one licence, and two completely different answers to the same question about British players.
Bonuses: the path is steep
Credit where it’s due: unlike plenty of offshore casinos, SpinKong prints its full bonus arithmetic, codes, caps, spin values and all. The headline 400% up to £1,000 with 250 free spins is a composite of three deposits: 120% up to £200 with 100 spins (code KONGSTART), 130% up to £300 (KONGRISE) and 150% up to £500 with 150 spins (KONGCROWN), each from a £20 minimum with seven days to clear. The wagering is 35x the bonus amount, and that number deserves consideration: the UK now caps wagering at 10x at licensed casinos, so this asks three and a half times what any UK site could, and a maxed first tier means £7,000 in bets inside a week. Winnings are capped too, at £1,000, £1,500 and £2,500 across the tiers, with free-spin winnings capped separately. High rollers get a gentler 20x on paired 50% matches up to £1,000 and £1,500 (minimum deposits £150 and £200), while the crypto route swings the other way: 150% up to £1,000 at a heavy 45x, capped at £5,000.
The first week is dense with follow-ons: Kong’s Lucky Seven pays 100 free spins for seven daily deposits under £100, Kong’s Golden Streak pays 200 for seven of £100 or more, and the Royal Deposit Cover returns 10% of a £500 first-week deposit total as cashback up to £150 at a modest 2x. After that, the calendar settles into reloads: 50 daily spins for a £30 deposit at 30x, tiered Monday spin packs, a Wednesday 50% match, a Thursday 60% match, and a twice-weekly 50% up to £1,000 for £300 depositors. The small print is consistent throughout: bonuses are non-sticky and can be cancelled without touching your own cash, the maximum bet while wagering is £5, spin winnings are capped per pack between £250 and £800, and a clause reserves the right to void winnings from any play the casino decides was aimed at profiting from the bonus, which is as open-ended as it sounds.
Payments and withdrawals: sterling upstairs, crypto underneath
The cashier page offers UK visitors card deposits from £20 to £4,000, bank transfer on the same limits, and a long crypto list: Bitcoin, Ethereum, Litecoin, Dogecoin, Tether and more, with gameplay currencies stretching to fourteen. Deposits are advertised as instant and fee-free, and the terms tell players to confirm with support which methods actually work in their region, an admission that the published list may not always be accurate. Withdrawals start at £50 and run to standard ceilings of £1,000 a day, £5,000 a week and £15,000 a month, with progressive jackpot wins exempt and higher limits promised for bigger depositors. Two fee clauses cut against the player: deposits wagered less than twice over may attract transaction fees at withdrawal, and processing fees can be deducted whenever a deposit sits unplayed.
Verification is mandatory before any withdrawal, covering identity, age and address, and the account rules are strict to the point of severity: masking your connection is banned outright, an IP overlap between accounts can end them all “without the possibility of appeal”, and an account left inactive for 90 days is classed as dormant, at which point the casino reserves the right to close it and retain any remaining balance. That last clause is worth reading twice, because it means money left sitting in a forgotten SpinKong account can simply be kept. My cashier verdict: the mechanics are modern, and the crypto side is quick by design, but the ceilings are low for the bonus sizes advertised, the discretionary fees are written into the terms, and the dormancy clause has no place in any casino a player should trust with a balance.
Support and complaints
Support runs through two channels: a live chat button that sits in the site menu and opens before sign-up, and the email address support@spinkong.com, printed on the About page. There’s no customer support phone number. The FAQ is six questions long and covers account creation, passwords, currencies and document uploads without ever addressing the questions that matter most, like how long a withdrawal takes; the payments page’s “instant” claim is the only processing time statement on the site.
The complaints route stays in-house from start to finish. The bonus terms direct unhappy players to support, then allow escalation “in accordance with the General Terms and Conditions”, and those general terms name no dispute body, no court, no jurisdiction and no regulator at all. For a UK player there’s no GAMSTOP, no independent adjudicator and no regulator with any practical reach, so any disagreement over a withdrawal ends wherever the casino decides it ends.
SpinKong Casino’s reputation
SpinKong’s has very little in its public feedback file. There’s no meaningful review presence, no complaint threads at the major mediation services, and nothing like the paper trail its older sisters have accumulated. The network it belongs to is another matter. The family’s record, set out in detail in my Queenwin Casino review, is heavy with reports of accounts frozen at the point of withdrawal, and there’s no reason to believe the shared cashier behaves differently depending on which mascot fronts it.
What SpinKong lacks in reviews it makes up for in marketing. A cluster of unofficial domains presents itself as the casino’s “official site” for Britain, spin-kong.org.uk, spinkong-uk.uk and spinkongcasino.uk among them, and the brand appears across lists of “non-GamStop casinos” published on repurposed British websites. Who built any of that, I can’t say, and I don’t attribute it to the operator. What I can say is what it means for players: a casino being sold to Britain specifically on the absence of GAMSTOP is being sold on a missing safety net, and anyone who has self-excluded should treat every one of those pages as a hazard. One more separation matters here: SpinKong has no connection to Spin King, the UKGC-licensed casino at spinking.co.uk run by Happytiger ApS under account 57641.
What I like, and what I don’t
What I like
- Bonus terms are printed: codes, caps, spin values, durations and wagering all stated plainly.
- Bonuses are non-sticky, and a player can cancel one at any point without losing their own funds.
- Live chat opens before sign-up, and a support email is printed on the site.
- The network behind it holds a current, open-ended Curaçao licence.
What I don’t
- No operator, licence, address or regulator is named anywhere on the site.
- Serves the UK in sterling with no UKGC licence, while its own sister sites block Britain outright.
- Wagering of 35x to 45x on the main offers, against the 10x maximum UK-licensed casinos may impose.
- Withdrawal ceilings of £1,000 a day, discretionary fees, and a dormancy clause that lets the casino keep abandoned balances.
- No ADR body, no phone line, and a complaints route that never leaves the building.
My SpinKong sister sites verdict
SpinKong is an odd mix of candour and concealment. On the surface it’s one of the more forthcoming offshore casinos I’ve reviewed: every bonus is documented to the penny, the spin values are printed, the withdrawal ceilings are stated, and the cashier works in the currency it advertises. But all that disclosure stops dead at the one question that underpins the rest, because nowhere, not in the terms, the privacy policy, the About page or the footer, does this casino say who owns it or under what licence it operates. The evidence points firmly at Hollycorn N.V. and its Curaçao licence, and that licence is current, but a casino this careful with its bonus maths doesn’t omit its own name by accident. Set beside a network that already lost one brand to a UK market block and now walls Britain off from most of the rest, the pattern reads like a company keeping SpinKong, another UK-facing brand, deliberately unsigned.
SpinKong sister sites FAQ: your questions answered
What are SpinKong’s sister sites?
The other brands on the Hollycorn N.V. network. The five profiled here are Queenwin Casino, BetnJet, Stay Casino, Casino Rocket and Plan Games, and the wider family includes Golden Crown Casino, North Casino, LimeWin, My777Bet and 50 Crowns among others. They share one operator, one Curaçao licence and the same platform underneath.
Who operates SpinKong?
Hollycorn N.V., a Curaçao company registered at Heelsumstraat 51, E-Commerce Park, Willemstad, though you won’t learn that from SpinKong itself: the site never names an operator, a licence or an address. The attribution comes from the network’s shared platform and terms, and from the licence reference its sister sites display.
Can UK players use SpinKong?
No. SpinKong has no UK Gambling Commission licence, the legal requirement for taking British custom, so it’s off-limits to UK players. Its restricted country list bars forty territories without ever mentioning the UK, and British visitors get sterling prices throughout, but none of the UK protections exists here: no GAMSTOP, no funds protection, no independent complaints route.
What is the SpinKong welcome bonus?
A 400% package up to £1,000 with 250 free spins, spread across three deposits: 120% up to £200 with 100 spins, 130% up to £300, and 150% up to £500 with 150 spins, each from a £20 minimum with seven days to clear at 35x wagering. That’s three and a half times the 10x maximum a UK-licensed casino could impose, and winnings are capped at £1,000 to £2,500 per tier.
Are SpinKong and Spin King the same casino?
No, and the one-letter difference matters. Spin King, at spinking.co.uk, is a UK casino run by Happytiger ApS under an active UK Gambling Commission licence, account 57641. SpinKong, at spinkong.com, is an offshore casino on the Hollycorn N.V. network with no UK licence at all. Search engines blur the two names, so check the address before trusting either.
