Important licensing note
My777bet takes sign-ups from Britain and prices its bonuses in pounds, but it has no UK Gambling Commission licence and names no licence of any other kind. That leaves British players without UK protections, without GAMSTOP, and without a UK authority to settle their disputes. In other words, players in Britain shouldn’t play at My777bet.

The My777bet sister sites
These My777bet sister sites all share one live chat support team, so I’ve chosen them for the themes that set them apart, from a crowned gorilla and a jester to a fishing trip.
SpinKong
- The closest sister site: More than half of My777bet’s terms read word for word the same as SpinKong’s, so the house rules will look very familiar if you’ve played at either.
- The gorilla one: The logo is a grey gorilla wearing a gold crown, beside gold lettering on a black background.
- Smaller bonus, bigger matches: Its three-deposit welcome offer is 400% up to £1,000 plus 250 free spins (120% up to £200 with 100 spins, 130% up to £300, then 150% up to £500 with 150 spins), against My777bet’s £2,800 total.
- Sports on the front page: Premier League odds appear on the homepage alongside the slots.
- Extra spins and cover: Kong’s Lucky Seven and Kong’s Golden Streak offer 100 and 200 free spins, and a Royal Deposit Cover worth 10% up to £150.
- Tighter withdrawals: The minimum withdrawal is £50, and the weekly limit is £5,000, compared with £20 and £7,500 at My777bet.
- Best for: Players who want a My777bet sister site with the same rules but a sportsbook front and centre and bigger matche deposit bonuses.
Spinchester
- The jester one: A grinning jester in a purple-and-gold hat fronts a dark purple site, with “Spin Chester” written in gold script, but no obvious connection to Manchester. Or Chester, for that matter.
- Spins you can keep: The welcome offer is 325% up to £3,000 plus 225 free spins over three deposits, and every one of those spins is wager-free, where My777bet’s spin winnings need 40x wagering.
- A jackpot of its own: The Jester’s Jackpot has its own place in the menu, next to a daily Bonus Wheel.
- Bonuses most days: Monday brings free spins, Tuesday offers a top-up, Thursday has a chest, the weekend adds a boost, and a daily chest gives up to 30 spins to anyone who deposited £20 the day before.
- A longer loyalty ladder: Its loyalty programme has 14 levels and 178 bonuses, whereas My777bet stops at five levels.
- Different software: It runs on its own platform in English, Dutch, and French, so it looks and works differently from the rest of the network.
- Best for: Players who’d like their welcome spins without strings attached and enjoy a busy weekly schedule of offers.
Royalen
- The royal one: A cheerful king in gold bursts out of a King of Spades playing card on a dark green homepage.
- One deposit does it: Royalen delivers its full welcome bonus, a 200% match worth up to £2,000 plus 200 spins, on a first deposit of £20 or more, with My777bet spreading the bonus over three deposits. The spins arrive at 50 a day over four days.
- Three wheels, not one: The Court Wheel requires a £50 deposit and pays up to £2,000, the Noble Wheel £100 for up to £4,000, and the Regal Wheel £250 for up to £10,000, against My777bet’s single £30 wheel.
- A crypto extra: Paying in crypto gets you a separate 300% bonus up to £100.
- Spins for using the app: Pay in through the Royalen app and you get 100 free spins, even if you’ve deposited before.
- Casino only: The casino has no sportsbook, just slots, live tables, game shows, and a Product Store.
- Best for: Players who’d rather get their whole welcome bonus in one go and like the idea of a bigger wheel for a bigger deposit.
Flouz
- The streetwear one: A mascot character in neon goggles and headphones sets the tone on a pink-and-purple site.
- Wager-free first spins: A first deposit of £20 brings 20 free spins, or 60 for £50, with no wagering on the winnings.
- Almost the same high roller bonus: It offers 100% up to £5,000 plus 150 free spins from £500 at 35x, close to My777bet’s 100% up to £5,000 plus 100 spins at 40x.
- Mondays and Fridays: The Diamond Drop gives 30, 70, or 150 free spins on Monday deposits of £20, £50, or £100, and a Friday reload matches 100% up to £200.
- More to play: Besides the casino and sportsbook, Flouz has virtual sports, scratch cards, lottery games, and the Mega Flouz Draw.
- Priced in euros: Unlike My777bet, Flouz shows offers in euros, even to UK visitors.
- Best for: Players who want wager-free spins on their first deposit and a few more ways to play than slots and sport.
Fish & Spins
- The fishy one: A plain blue logo tops a clean, white site that looks nothing like My777bet’s neon paradise, and the fishing theme comes through in the games.
- Its own fishing row: The Catch the Fish row gathers angling slots such as Big Catch Rush, Better Bass Cash, Big Boat Big Catch, and Ice Bass.
- A bigger spins cap: Its bonus terms cap winnings from welcome offer spins at £300, twice the 150 limit at My777bet, with 40x wagering on bonuses and spins.
- A longer bonus clock: Cash bonuses last ten days, compared with seven at My777bet.
- Points that grow in value: Loyalty points buy bonus cash at better rates as you climb, from 300 points for £5 at Bronze to 100,000 points for £5,000 at Diamond.
- Cricket at the tables: The live lounge includes Cricket Blackjack and Cricket Premier Blackjack from ICONIC21.
- Best for: Players who love fishing slots and prefer a calmer, plainer style to My777bet’s bright lights.

Is My777bet a Hollycorn casino?
My777bet is often listed as a Hollycorn N.V. casino, and it’s easy to see why people would want a name to hang it on. Hollycorn is a real Curaçao-based casino network company with a current licence, OGL/2023/176/0095, and it usually stamps its name on the casinos it operates. My777bet doesn’t. Its footer only says that “the Casino Online” has permission to run “on the basis of the international License”, without saying whose licence or where it was issued. The terms refer to “the Company” without ever saying which company, the About and Privacy pages don’t name one either, and the site has looked like that since it opened at the end of 2025.
Follow the clues, and they lead to Zefirius SRL of Costa Rica instead. My777bet’s server address is in a block of internet addresses registered to Zefirius SRL, the same block that hosts SpinKong, BetNjet, ReelWolves Casino, Royalen, and Flouz. Its live chat runs on the same support account as SpinKong, Spinchester, Royalen, Flouz, and Fish & Spins, and it shares its website software and its Google verification code with SpinKong, BetNjet, Royalen, Flouz, and ReelWolves Casino. The clincher is the rulebook: more than half the clauses in My777bet’s terms are word for word the same as SpinKong’s, including the rule on dormant accounts covered below.
None of these casinos names their operator, so the Zefirius link comes from public address records rather than anything the sites say about themselves. The wider family also includes ElaraBet, AmunBet, Revery Play, and FoxSlots.
A bonus for cancelling your withdrawal
The offer I like least at My777bet is the Cashout Cancellation Bonus. Ask to withdraw £100 or more and, if you qualify, the casino suggests you cancel 75% of it in return for a bonus worth 15% of the cancelled amount, up to £500, with 40x wagering. Totted up, cancelling £750 of a £1,000 withdrawal earns you £112.50 in bonus money, which then requires £4,500 of bets before you can take it out. The promotion’s own tagline is “Change your mind, boost your balance!”
A casino licensed in Britain couldn’t offer this. The Gambling Commission told licensed operators to stop reverse withdrawals in May 2020 and made the ban permanent in 2021, because being able to cancel a cash-out tempts people to carry on gambling with money they’d already decided to keep. Turning that temptation into a promotion works squarely against the player, and it’s as clear an example as I’ve seen of what you give up by playing at a casino without a UK licence.
£2,800 and 450 free spins, if you make three deposits
The My777bet homepage only advertises the first step: 100% up to £1,000 plus 100 free spins with the code WELCOME1. The second deposit brings 80% up to £800 with 150 spins, and the third 100% up to £1,000 with 200 spins, so the full welcome bonus comes to £2,800 and 450 free spins. Each step requires a £20 deposit, the bonus lasts seven days, spins arrive in batches over a few days, winnings from the spins are capped at £150, and you can’t win more than five times the cash part of the bonus.
The terms set 40x wagering for “the first and second deposit bonuses” and then say nothing at all about the third, even on the third bonus’s dedicated page. Leaving out the wagering requirements on an offer worth up to £1,000 is sloppy work. The first two steps alone mean £72,000 of wagering if you take the full £1,800. High rollers get a separate first deposit bonus of 100% up to £5,000 plus 100 spins for deposits of £500 or more, with the code VIP and 40x wagering.
After that, something runs most days. Monday Comeback returns 10% of your weekend slot losses, up to £100, with just 1x wagering, and the Monday 777 Free Spins Frenzy gives 20 to 200 spins depending on how much you deposit. The Lucky Reload is 50% up to £500 plus 50 spins on Wednesdays and Fridays, The Power of Thursday lets you pick 25 spins, a 50% bonus up to £50 with 10 spins, or £20 in bonus cash, and a daily Wheel of Fortune spin costs a £30 deposit. Most of these require 30x or 35x wagering.
There are two slots tournaments: the monthly 777 Grand Battle for £777, and the Weekly Showdown, which the tournament page lists as £300 plus 500 free spins while the promotions page says £300 plus 150 free spins. One of them is wrong, and it’s the kind of shoddy mistake that makes me wonder what else hasn’t been checked.
The loyalty programme has five levels, and its rules are written in euros, with one status point for every €30 you bet on slots. Bronze, at 200 points, means €6,000 of slot bets for 50 free spins. Gold, at 10,000 points, takes €300,000 of bets for 3% weekly cashback, and Diamond, at 50,000 points, needs €1.5 million for 10%. That’s a very long road for most players.
Two different limits on the same roulette bet
Section 14 of the terms limits real-money bets to £500 a round on roulette, game shows, and card games, £100 on slots, and £50 on fishing games, and warns that winnings from bets over the limit can be cancelled. The bonus terms tell a different story. They also say £100 on slots, but only £50 on cards, roulette, and lottery games, and they apply that to real-money play as well as bonus play.
So the most you can stake on a spin of the roulette wheel is either £500 or £50, depending on which page you read, and the casino keeps the right to void winnings either way. Rules that contradict each other on the very point where a big win can be taken away are worse than careless. Anyone thinking of playing table games here should assume the lower figure.
Instant crypto, but a week for a bank transfer
Deposits are free and instant. You can pay by bank transfer (£20 to £15,000), Visa or Mastercard (£20 to £5,000), Apple Pay or Google Pay (£20 to £1,000), or with Bitcoin, Ethereum, Litecoin, Dogecoin, Tether, Bitcoin Cash, USD Coin, XRP, Cardano, Tron, Solana, or BNB. Crypto withdrawals are listed as instant, up to €4,000 at a time. Visa and Mastercard withdrawals take 1 to 3 days (£20 to £4,000), and bank transfers take 5 to 7 days (£50 to £4,000).
The About page promises “lightning-fast withdrawals”, but a bank transfer can take up to a week. The limits don’t line up either. The payments page lets you ask for up to £4,000 at once, while the terms cap withdrawals at £1,000 a day, £7,500 a week, and £15,000 a month, unless you’re treated as a high-value depositor. You must wager each deposit at least once before withdrawing it, or the casino can take 20% off the payout. They also check your documents when you ask for your money, not when you sign up.
The rule on dormant accounts is a tough one. If you don’t use your account for 90 days, it’s classed as dormant, and the casino can close it and “retain any remaining balance”. You can ask support to reactivate it, but three months isn’t long at all, and a forgotten balance could simply be kept.
Neon sevens and 73 smaller studios
The look suits the name. The logo is a row of glowing pink sevens on purple slot reels, the site is deep navy, and the promotions are fronted by cartoon characters, including a mariachi guitarist on the first deposit bonus and a tiger in a red jacket on the Monday cashback.
The games filter lists 73 studios, including BGaming, Endorphina, Betsoft, Belatra, Zillion, Evoplay, Mascot, Platipus, Spadegaming, KA Gaming, TaDa Gaming, and Ela Games, with 100HP Gaming for crash games and Live Vegas, Absolute Live Gaming, and Luckystreak for the live tables. Pragmatic Play, NetEnt, Play’n GO, and Evolution aren’t among them, so fans of the best-known slots will have to look elsewhere.
The Top Games row opens with Burning Coins 40, Football 2026, Book of the Pyramids, Golden Buffalo, and Ice Bass, and the newest additions include Moofo, Burning Coins 100, Wolf’s Moon 3, and Event Horizon. There’s a crash games row with Triple Cash or Crash, Air Jet, and Astronaut, live roulette, blackjack, and Texas Hold’em, and a sportsbook beside the casino.
Support and feedback at My777bet Casino
Support is available via live chat or email at support@my777bet.com, and you can ask the chat team to exclude you if you need a break. The Responsible Gaming page points to GamCare, Gambling Therapy, Gamblers Anonymous, and Gordon House. The terms don’t include a complaints procedure, an independent dispute service, or the governing law, so the casino’s support team is the only route if something goes wrong.
My777bet’s Trustpilot profile has only ten reviews and a score of 3.1, which isn’t much to go on. The early reviews, from around the launch, praise the payouts, and one says a withdrawal took three days after some hard-going verification. The later ones are harsher. One player says documents were only asked for after a win and the money was never paid, and the most serious, from August 2026, says a win of over £130,000 on live roulette was cancelled for breaking the maximum bet, which is the very rule I picked out above for inconsistency.
A balanced view
Points in its favour
- Lots of bonuses, each with its own detail page and code.
- Monday cashback with only 1x wagering.
- Free, instant deposits by card, bank, Apple Pay, Google Pay, and crypto.
- Plenty of crash and fishing games to go with the slots.
Points against
- No operator or licence named anywhere on the site.
- A bonus for cancelling your withdrawal.
- Two different maximum bets for roulette and card games.
- No confirmed wagering requirement on the third welcome bonus.
- Balances can be confiscated after 90 days without play.
My My777bet sister sites verdict: lots of offers, too many catches
I can see the appeal. My777bet is bright and busy, the offers are in pounds, and there’s an offer of some sort on most days of the week. But the closer I looked at it, the more it seemed built to keep money in play rather than in your bank account, from a bonus for cancelling a cash-out to rules that can’t agree on how much you’re allowed to bet. Its sister sites share its support team, and SpinKong shares much of its rulebook too, so moving between them changes the theme and the size of the bonus far more than it changes how you’d be treated if something went wrong.
For players in Britain, the sensible thing is to look elsewhere. If you want slots and a sportsbook in one place, Dream Vegas, run by White Hat Gaming Limited under UK Gambling Commission licence 52894, gives 50 free spins on Big Bass Splash for a £20 first deposit with £10 played on slots, pays the spin winnings as cash up to £100, and, like every UK-licensed casino, isn’t allowed to let you cancel a withdrawal.
My777bet FAQ
Who owns My777bet?
The site doesn’t name an owner. Its server address is registered to Zefirius SRL of Costa Rica, which also hosts several of its sister sites, so that’s the company it’s tied to.
Is My777bet run by Hollycorn N.V.?
There’s no evidence that it is. Nothing on My777bet mentions Hollycorn, and its links all point to the Zefirius SRL family instead.
Is My777bet licensed?
It doesn’t name a licence, only an unnamed “international License” in its footer, and it has no UK Gambling Commission licence.
Can I cancel a withdrawal at My777bet?
Yes. It even offers a 15% bonus if you cancel 75% of a withdrawal of £100 or more, something UK-licensed casinos aren’t allowed to do.
What are the My777bet sister sites?
SpinKong, Spinchester, Royalen, Flouz, and Fish & Spins are the closest, and the wider family includes ReelWolves Casino, ElaraBet, AmunBet, Revery Play, FoxSlots, and BetNjet.
