The High Roller Casino sister sites in a nutshell
The High Roller Casino is one storefront on an unusually large offshore network. Its operator, Igloo Ventures SRL, holds a single Anjouan licence that lists more than forty casino domains, so its sister sites number in the dozens; the best-known include SlotMonster, Skyhills, Mega Dice, Lucky Block and WSM Casino.

Important licensing note
The High Roller runs on Anjouan licence ALSI-142311005-FI2, issued to Igloo Ventures SRL and in force, running from November 2023 to November 2026 on the regulator’s public register. The catch isn’t the licence’s validity but its reach and visibility: it stretches across more than forty High Roller sister casinos, and the brand it covers here names neither the licence nor the company anywhere a player would look. For a UK player, none of it applies in any case. There’s no UKGC oversight, no GAMSTOP, no independent UK dispute route and no protection of your deposit; Anjouan sits far outside the UK system, and this operator’s terms treat a British deposit not as a mistake to refund but as money to keep.

The High Roller Casino sister sites
This is not a tidy family of five; it’s a fleet. The Anjouan register lists more than forty casino domains against Igloo Ventures’ single licence, from crypto-first rooms to slot barns to sportsbook-led brands, and The High Roller sits among them, sharing the same licence number, the same offshore rulebook and the same service standards. Profiling all forty would be like reading you the phone book, so the five below are my pick of the ones that best show the network’s range and are best documented, two of which have full reviews on this site already. The shared points hold across the whole fleet: one Anjouan licence, no UK cover, and a track record on disputed payouts that our reviews of these brands keep running into.
SlotMonster
- The network’s founding brand: My full review identified SlotMonster as the anchor of the Igloo Ventures fleet, the clearest reference point for how the whole network behaves.
- Slots-led and sizeable: A library of some 3,000 titles with a flexible cashier, on the same offshore terms as The High Roller.
- The self-exclusion warning: We documented self-exclusion requests acknowledged and then ignored, and exclusion applied per account rather than per player, so a block on one brand leaves the other forty open.
- Same bonus shape: 35x wagering and a low win cap, the pattern repeated across the fleet.
- Who it suits: Not a UK player; read my review first if you want to understand the machinery behind The High Roller.
Skyhills Casino
- The crypto wing: A 2024-launched, crypto-forward brand on the same Igloo Ventures licence, also covered in full on this site.
- Fast coins, hard terms: Quick crypto payouts sit behind a 45x welcome wagering on bonus plus deposit, steeper even than The High Roller’s 35x.
- Where the disputes live: Our review found a weak record on disputed payouts and withheld winnings, the network’s recurring sore point.
- Family resemblance: Same master licence umbrella, same absence of an independent referee if a payout is refused.
- Who it suits: No UK player; a crypto user elsewhere who has read the payout record first.
Mega Dice
- The crypto casino headline act: One of the network’s most marketed brands, built around Telegram-era crypto play and a token of its own.
- Same licence, louder profile: It shares the High Roller’s Anjouan licence while pushing a bigger affiliate and influencer presence.
- Casino plus sportsbook: Like The High Roller it runs both verticals, so the comparison is close rather than cosmetic.
- No UK footing: No UKGC licence and the same restricted-territory stance as the rest of the fleet.
- Who it suits: Not a UK player; a crypto bettor abroad weighing one Igloo casino against another.
Lucky Block
- The crossover name: Better known to crypto audiences than casino ones, and named in the same online complaint threads that link this network’s brands together.
- Big-catalogue, crypto-first: Thousands of games and a wide coin list, on the shared Igloo platform and terms.
- Same paperwork gap: The operating company stays off the shopfront here too, exactly as on The High Roller.
- Marketing-heavy: Among the most aggressively promoted brands in the fleet, which is worth remembering when you read its “reviews”.
- Who it suits: No UK player; a crypto punter elsewhere who treats the hype with suspicion.
WSM Casino
- The token-branded room: Tied to the Wall Street Memes crypto project, a distinct front on the same shared Igloo licence.
- Casino and sportsbook: Another dual-vertical brand, so its shape mirrors The High Roller’s more than the pure slots siblings do.
- Shared machinery: Same welcome structure, same wagering weightings, same offshore dispute terms.
- No UK route: Unlicensed in Britain and restricted by its own terms, like every brand on this list.
- Who it suits: Not a UK player; a crypto community member abroad already within that project’s orbit.
How this review was made
What was checked, when and how, so you can judge the page on its evidence. Our full approach is on the About Us page.
Written by: Rob Hill
Research method: Desk researched from a UK connection. The live The High Roller site was read in full (general terms, bonus terms, promotions, footer, help pages), the Anjouan Gaming public register was searched for the operator, and the UK Gambling Commission register was checked the same day. No account was opened, and no money was deposited or withdrawn.
Checked on: 14 July 2026, on a Windows laptop using Google Chrome
Operator: Igloo Ventures SRL, named on the Anjouan register but nowhere on the High Roller site itself, which trades under its domain alone
UKGC account: None. A live register search for “highroller” on the checking date returned no results, so there’s no record to link to and no enforcement history to check.
Sources checked: The general terms (restricted territories and the forfeit clause, withdrawal limits, dispute resolution), the bonus terms (wagering, max bet, the two win caps), the live promotions and homepage, the anonymous footer; the Anjouan Gaming register entry for Igloo Ventures SRL with its full domain list; the UKGC business register; and our own published reviews of SlotMonster and Skyhills. Companies House: not applicable, no UK company involved.
Change log: 14 July 2026, first published version.
A big casino built for a big spender (on paper)
As a product, The High Roller is the polished end of this network. The lobby splits cleanly into casino and sportsbook, the game shelves run deep (multi-studio slots, a live casino floor, a set of in-house Originals, Megaways and bonus-buy sections), and a Jackpot Roller ticker rolls a four-tier progressive from a Mini pot up to a Mega above six million pounds. The sportsbook is a good one, complete with in-play, tournaments and a stack of football and tennis promotions. Nothing about the storefront feels thin; someone has spent money making this brand look like the VIP room its name promises.
The name is where the promise and the paperwork part company. A casino called The High Roller markets itself to big stakes, but its bonus terms cap the winnings you can take from a bonus at five times the deposit that triggered it, and its default withdrawal ceiling is £4,000 a day. The welcome banner offers “Fast Withdrawals” in the same breath as terms reserving the right to delay, suspend or decline them at the operator’s discretion. It’s a high-roller costume over a house-always-wins cashier, and the costume is the part they invested in.
Ownership, licensing and the UK position
Read the terms, and you never meet the operator. Clause 1.2 defines “we”, “us” and “our” as, simply, “thehighroller.com”; the footer’s copyright line credits the same web address; no company, and no jurisdiction of incorporation, appears anywhere on the site. The name Igloo Ventures SRL comes only from the Anjouan register, where this brand’s licence, ALSI-142311005-FI2, sits on one row beside more than forty other casino domains. That’s the network in a single screenshot: SlotMonster, Skyhills, Mega Dice, Lucky Block, WSM Casino and dozens more, all leaning on the same permission, none of them wearing the licensee’s name on the door.
The dispute machinery is built to circle. The terms promise to work with you for up to ninety days, then make “the records of the servers upon which the Services are run” the final authority on any dispute. Clause 19.3 tells you that if you think the operator has breached its licence you may contact the licensing authority “set out in, or linked to from, the footer of our Website”, except the footer sets out no such thing; there is no regulator named, no seal, no link. An independent route the terms gesture toward, and the website then withholds.
On the UK, this operator is unusually plain, and unusually harsh. The United Kingdom is listed among the Restricted Territories in clause 4.2; clause 4.4 states that funds deposited by anyone in a restricted territory “will be considered forfeit and will not be returned”. So a UK player here isn’t merely unprotected; they’re playing by a rule that treats their deposit as the casino’s to keep. No UKGC licence, no GAMSTOP, no ombudsman, and a forfeiture clause on top. The site loads in Britain and advertises the English Premier League to it; the terms would confiscate a British pound the moment it arrived.
The welcome offer, and two ceilings on the same win
The casino welcome is a 100% match up to £500 plus 50 free spins; the sportsbook runs a separate package worth up to £200 in free bets. On the casino side, the machinery is standard offshore: 35x wagering on the bonus before it becomes withdrawable, a £5 maximum bet while a bonus is live, seven days to use an offer before it expires, and contribution weightings that quietly do the heavy lifting: slots count 100%, table games 20%, and dice, arcade and roulette count nothing at all. Cash is spent before bonus funds, and requesting a withdrawal with wagering unmet forfeits the bonus.
Then the part worth slowing down to read: the bonus terms set two different ceilings on what you can win, a few lines apart. One says the maximum you can convert and withdraw is ten times the bonus amount; the other says maximum bonus winnings can be five times the deposit that triggered the bonus. On the flagship 100% match, where bonus equals deposit, the five-times-deposit cap is the one that bites, and it’s the lower of the two. So a brand named The High Roller, on its headline offer, limits a bonus win to five times what you put in, and prints the harsher of its two caps for anyone who reads to the end. There’s a 50% weekly reload and a 10% weekly cashback on net losses beyond the welcome, both useful, neither changing the shape of that ceiling.
Deposits, withdrawals and the discretion clause
The cashier takes cards, e-wallets and a broad crypto selection, generally without deposit or withdrawal fees, though the terms reserve the right to charge for currency conversion and, pointedly, to bill you for the cost of processing a deposit and a withdrawal if you cash out without wagering your deposit at least once. Withdrawals run back to the depositing method on a first-in, first-out basis, and the default limits are £4,000 a day, £10,000 a week and £20,000 a month, scaling only by arrangement. First withdrawals bring KYC, which is routine.
What gives the cashier its character is how much of it runs on the operator’s discretion. The terms let the casino delay or cancel withdrawals for further checks “at our sole discretion, from time to time”, freeze payouts during reviews, and decline or reverse withdrawals of unspent deposits until a source-of-funds check clears. None of that is unusual offshore, and much of it exists for real anti-fraud reasons; the issue is the total absence of anyone above the operator to appeal to when the discretion goes against you. The “Fast Withdrawals” on the banner are fast exactly until the casino decides they aren’t, and then the same document tells you its own server logs are the final word.
Support and complaints
There’s a live chat and a help centre, with email at support@thehighroller.com and a separate affiliates address. No customer support phone number is offered. For routine questions, the service is what you’d expect of a well-funded brand.
Complaints are where the network’s structure shows. The path is support, then escalation to a compliance department, then the ninety-day window, and after that the terms point you at a licensing authority “linked to from the footer” that the footer never names, and make the operator’s own server records the final authority in any dispute. There is no ADR provider, no ombudsman, no independent adjudicator anywhere in the process. If The High Roller decides against you, the last stop in its own written procedure is The High Roller.
The network’s record, and its marketing
The High Roller is young enough that its own name carries little settled player history, but it doesn’t stand alone; it stands in a fleet whose record I’ve already documented. Across our reviews of its sister sites, the same complaints recur: self-exclusion requests acknowledged and then not honoured, winnings withheld, and disputes over payouts that dead-end because there’s no independent body to escalate to. Player reports around this network describe deposits and bonuses that turn into problems precisely at the withdrawal stage, and the shared licence structure means a bad experience on one brand tells you something predictable about the next. This casino runs the same terms and the same cashier discretion as the brands where those problems appeared.
The reputation, meanwhile, is being manufactured with a familiar toolkit. Search the brand and you get a run of upbeat “reviews” planted on websites with nothing to do with gambling, a driving school, a home-services blog, a life-coaching site, several recycling the same promo code, alongside country-targeted write-ups pitching a UK-restricted casino to British and other audiences. Google flagged a result removed from its first page of search results by legal request. It’s the same pattern I’ve seen across this network’s other brands: little authentic feedback, a planted chorus of hype, and the less favourable parts pruned from search. A casino whose good word has to be bought is telling you what its honest word would have been.
What I like, and what I don’t
What I like
- A deep, well-built product: large slots library, live casino, in-house Originals and a full sportsbook.
- A four-tier progressive jackpot with a large Mega pot.
- An in-date, checkable Anjouan licence, and a 10% weekly cashback on net losses.
- Flexible payments including cards, e-wallets and crypto, usually fee-free.
What I don’t
- UK deposits are forfeited by the terms, on top of no UKGC licence and no GAMSTOP.
- The operator’s name appears nowhere on the site, and the promised complaints route dead-ends in an empty footer.
- Bonus winnings capped at five times your deposit, with 35x wagering and a £5 max bet.
- One licence shared across 40-plus casinos, with account-level self-exclusion that doesn’t apply to its sister sites.
- A network record of withheld winnings and unresolved disputes, and a manufactured search reputation.
My The High Roller verdict: big name, low ceiling
The High Roller is the best-dressed door on a very long corridor. Behind it, Igloo Ventures runs more than forty casinos off one Anjouan licence, and this brand gets the premium fittings: a real sportsbook, a deep casino, a six-million-pound jackpot. But the name writes a cheque the terms won’t cash. A casino selling itself to high rollers caps a bonus win at five times your deposit, ceilings your withdrawals at £4,000 a day, hides the company that owns it, and points any complaint at a regulator its own footer neglects to name. Strip the fittings, and it’s the same offshore machine as its forty sister sites, with the same missing referee, and I’ve watched that machine mishandle self-exclusions and disputed payouts on the brands where players stayed long enough to find out.
For UK readers there’s no line to walk here: no UKGC licence, the UK specifically named as restricted, and a clause that forfeits your deposit outright, which is about as clear a “not for you” as an offshore casino ever writes down. It’s off-limits, and its whole fleet of sister sitees with it. If the draw for you was a casino-and-sportsbook under one roof, LeoVegas runs exactly that inside the UK system, MGM-backed and UKGC-licensed, with GAMSTOP and a complaints route standing behind every bet. A big name is easy to paint on a door; the protection either sits behind it or it doesn’t, and here it doesn’t.
The High Roller Casino sister sites FAQ: your questions answered
What are The High Roller Casino’s sister sites?
More than forty casinos on the same Igloo Ventures SRL Anjouan licence, including SlotMonster, Skyhills, Mega Dice, Lucky Block and WSM Casino. They share the licence, the offshore terms and, in several cases, a documented record on disputed payouts; the register lists the full domain set on one line.
Who operates The High Roller Casino?
Igloo Ventures SRL, according to the Anjouan Gaming register, which holds licence ALSI-142311005-FI2 across dozens of casino domains. The company isn’t named anywhere on The High Roller site itself, whose terms and footer refer only to “thehighroller.com”.
Is The High Roller Casino legal for UK players?
No. It holds no UK Gambling Commission licence and doesn’t appear on the register. Its terms list the United Kingdom as a Restricted Territory and state that funds deposited from a restricted territory are forfeit and won’t be returned. There’s no GAMSTOP, no funds protection and no independent complaints route.
Is the licence in-force, or expired like some other Anjouan ones?
This one is actually in date: the Anjouan register shows Igloo Ventures’ licence running from November 2023 to November 2026. The problem isn’t validity but scope and disclosure, one licence covering 40-plus brands, with the operator’s name kept off the site and no independent UK-style dispute route behind it.
Why does a “high roller” casino cap winnings so low?
The bonus terms set two ceilings: ten times the bonus, and five times the triggering deposit. On the 100% welcome the five-times-deposit cap is the lower one and the one that applies, so a bonus win is limited to five times what you deposited, and daily withdrawals default to £4,000. The name promises big stakes; the small print keeps the payouts low.
