All six 666 Casino sister sites
These six sites share 666 Casino’s licence, software, and games, so what really separates them is how they look, what’s in their menus, and, in LadBet’s case, a sportsbook.
Dream Jackpot
- Pale and bright: Dream Jackpot is the only site in the group with a pale, almost white background, where 666 Casino is black and red from top to bottom.
- Round icons: Its menu is a row of round icons for Halloween, New, Hot, Drops & Wins, Slingo, and Megaways, with a search button at the start.
- Slingo has its own tab: You can go straight to the Slingo games here, which you can’t do from 666 Casino’s menu.
- Same top ten: Its top ten slots are the same as 666 Casino’s, in the same order, with Book of Dead and Gold Blitz Express among them.
- Straight questions: The guide on its homepage takes on questions such as “Are online casinos rigged?” and “Do online casinos let you win at first?”
- Best for: Players who’d like a 666 Casino sister site that’s easier on the eye.
King Casino
- The royal one: King Casino is black and gold, with a crown on its logo and gold buttons where 666 Casino uses red.
- Everything in the menu: Its top menu runs from Featured and Hot Slots through Slingo and Arcade to Live Casino and All Games.
- Live tables in plain sight: Live Casino is one click from the homepage, while 666 Casino has no Live Casino tab at all.
- A search bar you can’t miss: A full-width box under the menu lets you search by game or provider.
- Same spins: You get exactly the same wager-free spins as at 666 Casino, so the offer alone is no reason to choose King Casino.
- Best for: Players who want every type of game one click from the homepage.
Mr Luck
- Green on dark: Mr Luck swaps 666 Casino’s red for bright green buttons on a dark background.
- Casino only: There’s no sportsbook and no sports link anywhere on the site, so it’s slots and live tables like 666 Casino.
- The closest layout: Its menu of Home, Halloween, New, Hot Slots, Drops & Wins, Megaways, and All Games is almost the same as 666 Casino’s.
- Same quick games: Its homepage has the same arcade row as 666 Casino, led by Plinko 5,000, Instant Blitz, and Piggy Smash.
- Support around the clock: The homepage says its support team is there 24/7 for questions about withdrawals and account security.
- Best for: Players who like 666 Casino’s layout but could do without the devilish theme.
Red Casino
- Red all over: Red Casino does exactly what its name says, with a deep red page, a boxed logo, and a gold Join button.
- Prize pools on show: Its promotions page spells out the Drops & Wins prize pools, where 666 Casino’s only tells you how to find the games.
- Promotions in the menu: The side menu links straight to Promotions, alongside Popular Games, Hot Slots, and Megaways.
- Slingo included: The top menu has a Slingo tab, which 666 Casino’s doesn’t.
- No surprises: The welcome offer, the games, and the rules are the same as at the rest of the Jupiter Gaming casinos.
- Best for: Players who like to see what the prize pools are worth before they play.
Lad Casino
- Navy and gold: Lad Casino’s homepage banner shows Zeus, a big fish, and a cowboy with a treasure map, rather than the Big Bass phone the other casinos use.
- A sportsbook next door: The Sports link in its top menu takes you straight to LadBet, which 666 Casino has no link to at all.
- Plenty of Slingo: Its Slingo row includes Slingo The Godfather, Slingo Deadliest Catch, and Slingo Money Train.
- Help with payments: It has its own Deposit and Withdraw help pages in the footer, as well as the usual Payment Methods page.
- Arcade and live tables: Both have their own tabs in the menu, along with Megaways and Drops and Wins.
- Best for: Players who want a 666 Casino sister site with a sportsbook one click away.
Lad Bet
- The betting one: Lad Bet is the group’s sportsbook, and the only one of the seven sites where you can bet on football.
- A different offer: New customers get a £10 free bet when they bet £20, instead of 666 Casino’s 20 spins.
- Lots to bet on: The sports menu has in-play betting, boosted odds, and a bet builder, with everything from football and tennis to Aussie rules and alpine skiing.
- Black and yellow: It looks more like a betting shop than a casino, with a black background and yellow buttons.
- Slots through the Casino tab: For slots and live tables, the Casino tab at the top of the page sends you over to Lad Casino.
- Best for: Players who like a bet on the football as well as a spin on the slots.
How this 666 Casino review was made
Below is everything that went into my 666 Casino review, and my About Us page sets out how I review casinos generally.
Rob Hill
I tested 666 Casino from a UK connection the way a new player would, and searched its lobby for the games its own pages promise. I compared its offer, menus, and rules with each sister site, and checked the licence at the Gambling Commission. I didn’t open an account or make a deposit.

Best 666 Casino sister sites by player type
If you bet on sport too
Lad Bet is the only sportsbook in the group, with a free bet for new customers and Lad Casino a click away.
If you want live tables up front
King Casino puts Live Casino, Arcade, and Slingo at the top of its menu, so you don’t have to hunt for them.
If 666 Casino feels too dark
Dream Jackpot has the same games and spins on a bright, pale page with simple round icons.
If you like to know the prize pools
Red Casino is the one whose promotions page tells you what the Drops & Wins prizes are worth before you play.
The live games 666 Casino talks about, but doesn’t have
666 Casino is black and red, with “666” picked out in red in its logo and “Relight Your Fire!” written underneath. Along with the usual slot categories, the menu has a Halloween tab (all year round, in keeping with the Devilish theme) and a lucky 777 tab, and the homepage opens on its Big Bass Splash offer.
The slots are the main event. The All Games page lists 922 games, and its provider filter shows where they come from: Pragmatic Play makes 433 of them, followed by Play’n GO with 144, Games Global with 122, Blueprint with 69, Wazdan with 59, and Gaming Corps with 42. Fishin Frenzy Lure Em In, Big Bass Splash, 3 Pigs of Olympus 2, Book of Dead, and Gold Blitz Express were at the top of the top ten when I looked, and there are Jackpot King progressives such as Eye of Horus and Deal or No Deal Megaways further down. An arcade row has quick games like Plinko 5,000, Banknote Blitz, and Piggy Smash, each showing its maximum win.
The live casino is there, but it has no tab in the menu, so you’ll have to find it through the footer or the All Games filter. It has game shows such as Money Time, Mega Wheel, and Sweet Bonanza CandyLand, roulette tables including Mega Roulette 3000 and PowerUP Roulette, and a run of multi-hand blackjack tables.
The trouble is what the site says it has. Its live casino page invites you to play “Lightning Roulette, Instant Roulette Live, Roulette First Person, American Roulette Live, and many, many more”, and names Power Blackjack and Infinite Blackjack. The homepage adds Crazy Time and Monopoly Live, and slots such as Starburst and Rainbow Riches Megaways. 666 Casino’s own game search finds none of them, apart from a Slingo version of Starburst. That’s sloppy at best, and misleading to anyone who signs up to play a game that isn’t there.
The same 20 spins at every Jupiter Gaming casino
The welcome offer at 666 Casino is 20 spins on Big Bass Splash, worth 10p each. To get them, you opt in, deposit at least £20, and wager £20 on Big Bass Splash, and once you’ve done that, you have seven days to claim the spins. Anything you win from them is yours to withdraw, with no wagering. The offer is for new UK players and is limited to one per household.
It’s a small offer, but an honest one, and to be fair to 666 Casino, wager-free spins beat most bonuses on UK sites. One rule is worth knowing before you start. If you withdraw your deposit before you’ve played it through, you lose the spins, or any winnings from them, and you have to contact support to make that withdrawal at all.
Dream Jackpot, King Casino, Mr Luck, Red Casino, and Lad Casino run exactly the same offer, so there’s no point shopping around the group for a better one, and Lad Bet’s £10 free bet is the only different deal. None of the seven advertises a no-deposit bonus. Beyond the welcome offer, the promotions page has little more than a guide to Pragmatic Play’s Drops & Wins games and a teaser for the next seasonal event. That sits oddly with the About Us page, which promises “ongoing promotions and loyalty rewards” and a welcome bonus that gives you “a boost to your bankroll”. The casino has no loyalty scheme, and £2 of spins isn’t much of a bankroll.
Jupiter Gaming Limited took 666 Casino over from AG Communications
UKGC Licensed, Jupiter Gaming Limited (67098), click to verify
Jupiter Gaming Limited is based at 9 Bond Street in St Helier, Jersey, and it has held UK Gambling Commission licence 67098 since 28 August 2025, covering remote casino, bingo, and betting, with no regulatory actions on record. The footer of every one of its sites also lists a Jersey Gambling Commission licence, RGO-2600-30, and says the games run on software from iGamingCloud Limited, which holds its own UK licence.
666 Casino, Dream Jackpot, King Casino, Mr Luck, and Red Casino all used to be run by AG Communications Limited, a Maltese company whose own entry on the UK register now lists every one of its brands as inactive. In February 2025, AG Communications agreed to pay £1,407,834 to settle a Gambling Commission review. The Commission found that between May 2023 and October 2024 it had failed to meet anti-money laundering rules and social responsibility rules on interacting with customers and identifying them, and that its self-exclusion controls fell short between October 2022 and May 2024. That’s AG Communications’ record, not Jupiter Gaming’s, but it’s the history 666 Casino comes with.
Jupiter Gaming’s UK Gambling Commission register entry lists eight active domains: the seven sites on this page and rightbet.com, whose footer still names Betable Limited as its operator. Ivy Casino, Rose Casino, and O’Reels Casino are on the same entry as inactive names, and they’re listed on Betable Limited’s licence instead.
One self-exclusion covers all seven sites
If you’re thinking of moving to a sister site after taking a break from 666 Casino, this is the part to read. If you take a cooling-off break of between 24 hours and six weeks at 666 Casino, it applies to all your accounts on the network. Self-exclusion, which runs from six months to five years, works the same way, and the terms say that while it’s in place you can’t open or use an account at any Jupiter Gaming site. You also can’t sign up if you’re registered with GAMSTOP.
You’re allowed one account per brand, and the terms list some playing habits as “prohibited practices” that can get your winnings cancelled. Placing a single bet worth more than 25% of your first deposit is one of them, so £5 is the most you’d want to stake in one go after a £20 deposit. Betting systems such as Martingale are banned too, and so is covering 24 or more numbers on a roulette spin.
If you don’t deposit, bet, or withdraw for 12 months, you’ll get an email, and you then have 30 days to use your account. After that, 666 Casino tries to send your balance back to your last payment method, and the terms don’t mention any fee. If that doesn’t work, the money is held for you to claim at any time.
A one-line payments page, and no payout guidance
666 Casino’s Payment Methods page lists just one option: Visa and Mastercard debit cards, for deposits and withdrawals. The footer also shows an Apple Pay logo, but the payments page doesn’t mention it. You can deposit from £10 up to £2,000 at a time, and the minimum withdrawal is £10, though support can help with smaller amounts. Withdrawals go back to the card you paid in with, and jackpot wins over £10,000 may be paid by bank transfer. Neither the payment page nor the terms say how long a withdrawal takes. Your balance is kept apart from the company’s own money, but the terms rate that as “Not Protected”, which means it could be counted as the company’s assets if it went bust.
You can contact support via live chat or email at support@666casino.com, and the terms say they have a 24/7 team. There’s no phone number. Support should answer a complaint within three working days, and a manager within ten if you escalate it. If it’s still not sorted after eight weeks, or you get a final response you don’t accept, you can take it to IBAS for free within 12 months. The footer still gives the 0808 8020 133 helpline number under the BeGambleAware name, even though GambleAware closed in March 2026. The number itself is the National Gambling Helpline, so it’ll still get you help.
666 Casino’s reputation
666 Casino’s Trustpilot profile, claimed by the business in October 2023, has 279 reviews and an average of 1.7, and the casino hasn’t been replying to negative ones. The complaints keep coming back to the welcome offer, with players saying their spins never arrived or that they got fewer than they expected. Others mention deposits that didn’t show up in their balance, accounts restricted with a short email saying they no longer fit “the criteria”, and plenty of frustration about losing. One reviewer puts it bluntly: the site advertises games you can’t play, which matches what I found in the live casino. In fairness, a couple of recent reviews praise fast withdrawals and helpful support, so it isn’t all one way.
What I like, and what I don’t
What I like
- Wager-free welcome spins, with the terms written plainly.
- One cooling-off or self-exclusion covers every Jupiter Gaming site.
- A clean record so far under Jupiter Gaming’s UK licence.
- Free disputes through IBAS.
What I don’t
- Live games named on its homepage that aren’t in the lobby.
- A payments page that names only debit cards, and no withdrawal times.
- Customer funds rated “Not Protected”.
- Loyalty rewards promised on the About Us page, but nowhere to be seen.
My 666 Casino sister sites verdict: seven sites, one casino underneath
I’ll be honest, there isn’t much to choose between 666 Casino and its sister sites once you look past the colours. The games, the offer, the rules, and the people in charge are the same everywhere, which is good news if you like the slots and bad news if you were hoping a sister site would treat you differently. What lets 666 Casino down is carelessness rather than anything sinister: copy that promises games it doesn’t offer, an About Us page that oversells, and very little information about getting your money out.
If the devil theme appeals and Big Bass Splash is your sort of slot, 666 Casino is a fair place for a small, wager-free start, as long as you don’t sign up for the live games it mentions. For football bettors, LadBet is the more useful 666 Casino sister site, and if you’d rather have every game in the menu, King Casino is the tidier option.
