The HeavyBet sister sites in a nutshell
HeavyBet is a fight-themed casino and sportsbook operating under Win Top Ltd’s Anjouan Gaming licence. I’ve picked out five of its sister sites with very different themes: Spinathlon, Villa Spin, SherLuck, Ragnabet, and Big Drago.

Important licensing note
HeavyBet isn’t licensed by the UK Gambling Commission, its website doesn’t name the company behind it, and its Terms of Service name the United Kingdom among the countries it bars. If you’re in Britain, you’d have no UK protections, no GAMSTOP, and no UK regulator to turn to, so my advice is to stay away.

Five HeavyBet sister sites, from a changing room to a dragon’s lair
Win Top builds every one of its casinos on the same software, with the same lobby and rulebook, and then gives each a costume. These HeavyBet sister sites wear some of the more memorable ones, and their casino welcome offers are around five times the size of HeavyBet’s, although they come with conditions of their own.
Spinathlon
- A football dressing room: The Spinathlon homepage is set in a changing room with shirts on the pegs, and the lobby has a Penalty Series row of football slots.
- A bigger welcome bonus: The casino welcome pack is 460% up to £14,500 plus 460 free spins, against HeavyBet’s 300% up to £3,000.
- A sports offer with strings: The “150% up to £115” sports pack is really three 50% free bets of up to £30, £40, and £45, for football accumulators where every leg must have odds between 8.00 and 20.00.
- Unfinished terms: One clause still says the rules on void legs are “subject to clarification with Betby”, the sportsbook supplier. That’s sloppy to leave in published terms.
- Best for: Slots players who like a football theme and will ignore the sports offer.
Villa Spin
- The high life: Villa Spin’s homepage is a marina full of white villas, with a sports car open on the quayside and a Bitcoin held up to the camera.
- The biggest welcome bonus here: Its casino welcome pack is 500% up to £15,000 plus 620 free spins, the largest of the six sites profiled on this page.
- A VIP route: The VIP welcome pack offers 750% up to £12,000 across four deposits, each of at least £250, with 40x wagering requirements to clear in seven days.
- A capped prize: You can only withdraw 3x the bonus from the first step and 5x from the rest, no matter how well you do.
- Best for: Big-spending players who want the largest bonuses in return.
SherLuck
- A detective story: SherLuck’s homepage stars a detective in a deerstalker hat studying a Bitcoin in a book-lined study.
- A themed set: The SherLuck lobby has an Evidence of Luck row, which suits the theme nicely.
- Familiar figures: SherLuck’s casino welcome pack offers 430 free spins with its 430% match up to £14,500, and its VIP pack goes up to £10,000 at 700%.
- The usual sports pack: SherLuck’s sports welcome pack is 150% up to £115, just like Spinathlon’s.
- Best for: Anyone who’d like a bit of Victorian mystery with their slots.
Ragnabet
- A warrior of its own: A Valkyrie in gold armour stands in a sunlit Norse hall on the Ragnabet homepage, so it’s the closest match to HeavyBet’s fighting spirit.
- Norse slots: The Ragnabet lobby has its own Asgard’s Gold row.
- A large welcome offer: The casino pack is 420% up to £15,000 plus 440 free spins, with a VIP pack of 500% up to £10,000.
- Sport as well: Ragnabet has a sportsbook and the family’s standard 150% up to £115 sports pack.
- Best for: Fans of Norse mythology who’d like a casino and sportsbook in one place.
Big Drago
- Here be dragons: A huge white dragon wraps itself around a smiling woman on the Big Drago homepage.
- Broken banners: When I checked, the crypto banner read “110% Up To $num=1250$ USDT”, and the casino banner had a similar “$num” code where the figure should be. That’s a basic mistake, and one that should have been spotted before it went live.
- A smaller VIP pack: Big Drago’s VIP welcome pack is 210% up to £5,000, the smallest at these five HeavyBet sister sites.
- Casino first: Its homepage banners don’t include a sports welcome pack.
- Best for: Fantasy fans, once the errors are fixed.
How this HeavyBet review was put together

Rob Hill
I visited HeavyBet from the UK, opened every welcome offer and read its full terms, and compared the sports offer with those of its sister sites. I confirmed the licence with the regulator in Anjouan.

Who’s in HeavyBet’s corner?
HeavyBet doesn’t tell you. The Terms of Service start with “Website: heavybet.com” and refer to “the Website” from then on, with no company name or licence number anywhere in them. The sports offer terms call the operator “the Organizer”. For a site that wants your card details, that isn’t good enough.
The Anjouan Gaming register fills the gap. A search for heavybet brings up Win Top Ltd, licence ALSI-202509029-FI1, issued on 16 September 2025 and valid until 15 September 2027. The same entry lists 31 casino domains, including heavybet.com and all five of the sister sites on this page. As with the rest of the HeavyBet sister sites group, they all share the same platform, offer panels, and terms, with only the theme and the figures changed.
UK players: ruled out in the terms, waved through at sign-up
The HeavyBet Terms of Service include the United Kingdom in a list of restricted countries, and say residents can’t play for real money there. Break that rule, and the terms say HeavyBet can’t promise to process your withdrawals or refunds.
However, the site does everything it can to make British players feel at home. The offers are listed in pounds, there’s a Union Jack in the header, the payments page lists Monzo, Revolut, and UK banks, and the Register form opened when I tried it from the UK. Taking deposits from British players while keeping a clause that lets you refuse their withdrawals isn’t a fair way to treat anyone.
The one sports offer in the family worth reading twice
HeavyBet’s sports welcome bonus is the most interesting thing about it. It’s worth up to £225 in free bets, split across your first three deposits: the first earns a free bet worth 100% of the deposit (up to £100), the second 75% (up to £75), and the third 50% (up to £50). The minimum deposit for each is £20, and the free bet only becomes due once that deposit has been staked on sport and the bets have settled. Getting the full £225 means depositing and betting £100 three times over.
What makes it stand out is how few strings are attached to the free bets themselves. The terms say there’s “no minimum odds requirement”, the free bets can be used on any sport, before or during a match, and the winnings are paid as real money with no wagering requirements, up to £500 per free bet. Compare that with the sports welcome pack on Spinathlon, SherLuck, and Ragnabet, where Spinathlon’s terms limit you to football accumulators with every leg priced between 8.00 and 20.00.
There are catches, though. You have to ask customer support for each free bet once your qualifying bets have settled, and taking a casino bonus in between ends the offer. The terms also disagree with themselves: clause 5 says the promotion is only available for seven days after you register, while clause 14 gives you 30 days to complete all three steps. That’s the kind of contradiction that could cost you a free bet.
A casino bonus that shrinks when you open it
The HeavyBet homepage advertises a Welcome Pack of 300% up to £3,000 plus 300 free spins. Open the offer panel behind it, though, and you only get the first step: a £750 maximum at 100%, plus 300,000 shop chips and 50 spins on the Hot Chilli Bells 100 slot. The minimum deposit is £20, the wagering requirement is 45x the bonus within seven days, the maximum bet is £5, and you can only convert winnings worth up to 5x the bonus. The offer panel doesn’t show the other steps.
The other casino offers are aimed at regular depositors. The High Roller bonus is 100% up to £1,500 plus 100 free spins on Gold Rush, from a £500 deposit, with 45x wagering. Monday Madness gives 150 free spins for a £50 deposit, with winnings capped at £100 and 40x wagering within three days. The Weekend Bonus adds 40% up to £400 on Fridays and Saturdays, from £30. The chips go towards a shop that lists a Lamborghini Urus at 127.2 billion chips, which tells you how seriously to take it.
Fight Nights and a famous face
The star of HeavyBet’s banners is an animated Conor McGregor, who holds up a World Cup trophy as confetti falls over a full stadium on the sports banner and plays golf beside a pile of cash on the Monday Madness one. The logo replaces the letter T with an MMA glove, and the lobby is picked out in black and red with a gold menu bar.
The theme carries into the lobby with a Fight Nights row, with Boxing King, Lucky Punch Megaways, Fist of Destruction, Wrestling Queen, Boxing Roo, and Boxing Champion. Beyond that, the HeavyBet lobby is standard Win Top fare: a Top row led by Black Wolf 2, Snoop Dogg Dollars, and 3 Super Hot Chillies, plus rows for live games, roulette, blackjack, and game shows. There’s also a full sportsbook, which is where HeavyBet differs from some of its sister sites.
Paying in and getting paid at HeavyBet
The payments page lists cards, Monzo, Revolut, and online banking for deposits of £20 to £2,000, Apple Pay and Google Pay for £20 to £800, and nine cryptocurrencies for £20 to £10,000. Withdrawals range from £50 to £4,000 by bank transfer, £50 to £2,500 by card, and £50 to £10,000 in crypto.
According to the Terms of Service, payouts are handled within three business days, although no times are given for individual methods. You’re expected to wager your deposit at least once before withdrawing, or the site may charge a fee, and anything over the monthly limit is paid in instalments. If you don’t log in for 12 months, a £10 fee comes out of your balance every month.
Support, and what players say about HeavyBet
You can reach support by live chat or at support@heavybet-support.com, while block@heavybet-support.com handles self-exclusion. As an offshore site, HeavyBet isn’t part of GAMSTOP.
There’s no Trustpilot profile for heavybet27.com. The one called HeavyBet Casino turns out to be an old profile for softwarepox.com that’s been renamed, and its 2.3 rating mixes 2023 reviews about software with seven casino reviews from August to October 2026. Six of those seven give one star, which isn’t a promising start.
A balanced view
Points in its favour
- Free sports bets as a bonus, with no minimum odds.
- A fight theme that runs right through to the lobby.
- A full sportsbook with live betting.
Points against
- No UK licence, and the UK is on its restricted list.
- No operator name anywhere on the site.
- A £3,000 casino welcome bonus pack whose info panel only covers the first £750.
- Promotion terms that give you 7 days to clear wagering requirements in one clause and 30 in another.
My HeavyBet sister sites verdict: a decent free bet, but a mismatched fight
I’ll be honest, HeavyBet surprised me. Its sports free bets are more generous and much simpler than the ones on its sister sites, and the fight theme is carried out with real commitment. If this were a UK-licensed bookmaker, I’d be pointing sports fans towards it.
It isn’t, though. The operator stays nameless, the terms bar British players while the cashier happily takes their money, and you’d have no regulator to call if a withdrawal went wrong. If you want a free bet without the gamble on whether you’ll be paid, LiveScore Bet, run by LiveScore Betting and Gaming (Gibraltar) Limited under UK Gambling Commission account 56859, gives new customers £30 in free bets for a £10 bet at odds of 1.5 or more. There’s no need to ask support for it, either.
