The BetMGM sister sites in a nutshell
BetMGM’s active sister sites are LeoVegas, BetUK, Pink Casino, SlotBoss and 21.co.uk. They all sit under LeoVegas Gaming PLC, UKGC account 39198.
If you want the closest all-round sister brand, LeoVegas is the obvious pick. If you want the nearest sportsbook-led option, I’d look at BetUK. If the casino side matters more than the sport, 21.co.uk, Pink Casino and SlotBoss give you cleaner casino-first alternatives without pretending to be American.

The BetMGM sister sites worth knowing
The LeoVegas Gaming list is an interesting one because the brands don’t all do the same job. BetMGM sells the MGM Resorts fantasy, LeoVegas gives you the group’s own mature casino-and-sports brand, BetUK keeps things more sportsbook-facing, and the other three lean into casino in different ways.
LeoVegas
- Identity: The group’s flagship casino and sportsbook brand, with less Vegas theatre and more established European casino polish.
- Best for: BetMGM players who like the LeoVegas account base but want the group’s original UK-facing brand rather than the MGM stage show.
- What feels similar: Same UKGC licence, same operator, similar payment options and a strong mix of casino, live casino and sport.
- What feels different: LeoVegas feels more casino-native and less celebrity-led, while BetMGM feels built around showbiz, jackpots and American resort energy.
- Why it matters: It’s the smartest sister site move if you want the same group without the Las Vegas costume.
BetUK
- Identity: The most straightforward sportsbook-led sister brand in the LeoVegas Gaming family.
- Best for: BetMGM users who want football, racing and betting tools without quite so much gold-plated entertainment branding.
- What feels similar: UK sportsbook, casino alongside it, same licence account and the same LeoVegas group infrastructure.
- What feels different: BetUK is more practical and less theatrical. BetMGM wants to feel like a night out. BetUK wants to feel like a betting account.
- Why it matters: It’s the sister site I’d pick if your BetMGM habit is mostly about sport rather than MGM Millions, exclusives or live casino gloss.
21.co.uk
- Identity: A casino-first LeoVegas Gaming brand with a live dealer flavour rather than BetMGM’s sports-and-entertainment pitch.
- Best for: Players who use BetMGM mainly for casino and don’t need the American sportsbook branding around it.
- What feels similar: Same active UK licence, same group standards and plenty of mainstream casino and live casino overlap.
- What feels different: 21.co.uk feels more focused and more traditionally casino-led, while BetMGM is trying to be sportsbook, casino and Vegas resort all at once.
- Why it matters: It’s the strongest alternative if the casino lobby is what you care about and BetMGM comes with too much noise.
Pink Casino
- Identity: A casino-only sister brand with a clearer slots-and-live-casino focus.
- Best for: BetMGM players who want a lighter casino site and don’t care about sports betting at all.
- What feels similar: Same LeoVegas Gaming licence, same basic account logic and the same wider MGM-owned group behind the scenes.
- What feels different: Pink Casino feels smaller, simpler and more casino-specific, while BetMGM is much louder.
- Why it matters: It’s the best contrast if BetMGM’s sports, jackpots and Vegas packaging feel like too much theatre.
Slot Boss
- Identity: The slots-first sister brand, with a name that tells you exactly where the emphasis sits.
- Best for: Players who open BetMGM for reels, jackpots and promotions rather than sport or live tables.
- What feels similar: Same licence family and a familiar LeoVegas Gaming approach to slots, bonuses and account controls.
- What feels different: Slot Boss doesn’t need the MGM resort connection to sell itself. It’s much more direct about being a slot site.
- Why it matters: It’s the best move if you like the casino side of BetMGM but don’t want the sportsbook-and-showbiz layer.
Yes, BetMGM has real UK sister sites
The UKGC record for LeoVegas Gaming PLC lists 21.co.uk, betmgm.co.uk, betuk.com, leovegas.co.uk, pinkcasino.co.uk and slotboss.co.uk as active domains. That makes LeoVegas, BetUK, Pink Casino, SlotBoss and 21.co.uk the only BetMGM sister sites in Britain. The inactive names on the record, including older bingo and LeoVegas.com entries, don’t add anything to the picture anymore.
Best picks by player type
Best if you want the closest all-round sister site
LeoVegas is the obvious pick if you want the same operator style with less MGM showmanship and more established casino polish.
Best if sport is the whole point
BetUK is the sister site move if you mainly want sportsbook, racing and football rather than a casino focus.
Best if you want the strongest casino-only feel
21.co.uk makes the most sense if you want a proper casino-led brand and don’t need BetMGM’s Vegas skin.
Best if you want something lighter
Pink Casino is the softer, smaller-feeling route for players who find BetMGM a bit too much.
Best if you only care about slots
Slot Boss is the straightest answer if your BetMGM interest starts and ends with reels, free spins and jackpot games.
Ownership, licensing and the UK position
BetMGM is legal for players in Great Britain. The UK operator is LeoVegas Gaming PLC, UKGC account 39198, with active permissions for bingo, casino, general betting standard real event and general betting standard virtual event. The register currently shows no regulatory actions.
The corporate story is more layered than that of a typical UK casino. LeoVegas became part of MGM Resorts International in 2022, and the UK BetMGM launch made heavy use of that Las Vegas connection. The site itself makes the most of its connection to MGM Resorts, with references to names such as Bellagio, Aria, Cosmopolitan, MGM Grand, Mandalay Bay, Park MGM, New York-New York, Luxor and Excalibur.
There is also the wider BetMGM name in the United States, which is a major sports betting and iGaming business associated with MGM Resorts and Entain. For UK players, though, the practical licence answer is simpler. The site you’re using at betmgm.co.uk is operated on the LeoVegas Gaming PLC account.
The Chris Rock-led launch campaign tells you how BetMGM wanted to arrive here: loud, famous and unapologetically Las Vegas. The ASA later considered complaints about whether the TV ad had strong appeal to under-18s and didn’t uphold them, but it clearly ruffled a few feathers upon landing.
The welcome offers are simple and very on-brand
The main sports welcome offer is Bet £10, get £40 in free bets. New customers choose the sports welcome offer, deposit £10 or more within 7 days, and place a qualifying sports bet of at least £10 at minimum odds of evens, or 2.0. Each-way bets need a £10 each-way stake, so £20 total.
The reward is 4 x £10 free bets: 2 x £10 sports free bets and 2 x £10 Bet Builder free bets. The Bet Builder free bets need minimum odds of 3/1, or 4.0. Free bets, profit boosts and odds boosts don’t count towards qualification, and the qualifying bet can’t be void, cashed out or partially cashed out. Virtual sports, esports and non-UK or non-Irish horse racing are excluded.
The casino welcome offer is 200 free spins on Big Bass Splash. You opt in, deposit £10 within 7 days, then wager £10 on eligible casino games. The free spins are worth 10p each, are available only on Big Bass Splash, and expire 3 days after being credited. There’s no wagering requirement on the free spins or on winnings from them, which is the part I like most.
The casino rules still need reading. Slots, instants and Slingo usually contribute 100% to the qualifying wagering, but some games contribute less, and plenty contribute nothing. Live casino and table games don’t help you unlock the welcome spins, so this is really a slots route, not a general casino route.
Payments, withdrawals and KYC
BetMGM’s cashier is neat and tidy. The available payment methods are payment card, bank transfer, PayPal and Apple Pay. The minimum deposit is £10 across all listed methods. Maximum deposits are £3,000 for payment card and Apple Pay, and £10,000 for bank transfer and PayPal.
Withdrawals also start at £10. The maximum withdrawal is £8,000 for payment card, £35,000 for bank transfer, £4,000 for PayPal and £8,000 for Apple Pay. The site says approved withdrawals typically arrive within 1 to 3 business days.
The closed-loop rule is standard but important. BetMGM asks you to withdraw using the same method you used to deposit where possible. It also says payments to and from the account may show as BetMGM or LeoVegas on bank statements, which is useful to know before you start wondering who’s touched your balance.
KYC is built into the account opening process. BetMGM says you can’t deposit until your name, address and date of birth have been verified. If extra documents are needed, they can include a photo ID, proof of address, proof of payment method, and source-of-funds documents. Document confirmation can arrive quickly, but manual review may take up to 3 business days.
Why BetMGM feels bigger than most UK launches
BetMGM doesn’t do anything by half. The brand arrived in the UK as though it had already won the room, with Chris Rock on the adverts, Las Vegas references everywhere, and a golden-era pitch that made ordinary betting offers feel like part of a larger entertainment package.
The sportsbook backs up enough of that noise to make the positioning credible. The site pushes football, horse racing, tennis, major competitions, in-play betting, Bet Builder and Golden Goals, its free-to-play score predictor. It also has visible UK sports partnerships, including football club links and the BetMGM Premier League Darts.
The casino side is just as central to the identity. BetMGM promotes slots from Pragmatic Play, Big Time Gaming, Barcrest, NetEnt, Play’n GO, Microgaming and ELK, with named games including Book of Dead, Vegas Megaways, Immortal Romance, 7s on Fire, Aloha! Cluster Pays, Sugar Rush and Vegas Diamonds.
Live casino gets real space too, with Instant Live Roulette, Exclusive Free Bet Blackjack, Grand Baccarat Live, Unlimited Blackjack, BetMGM Roulette, Crazy Time Live and Snakes and Ladders Live all part of the pitch. This isn’t a sportsbook with a casino hidden at the back. It’s a sportsbook and casino brand that wants both halves to feel like a show.
Support and complaints
BetMGM’s support setup is easy enough to follow. The site points players towards the Help Centre, Live Chat and email. Logged-in customers get a better chat experience because the system already knows who they are and can keep the chat history together.
Support route: Help Centre, Live Chat and email
Email: support@betmgm.co.uk
Phone number: No general customer support phone number, though logged-in players can request a callback with at least 24 hours’ notice
The complaints process starts with customer support. If the issue can’t be resolved straight away, BetMGM asks for the complaint by email and says it will acknowledge it within 24 hours. If the final response doesn’t solve it, or if the complaint hasn’t been resolved within 8 weeks, the dispute can go to IBAS.
That’s a decent complaint route. I’d still prefer a published support phone number for a brand this high-profile, but the combination of live chat, email, callback request and IBAS gives players a clear route through the system.
What I like, and what I don’t
What I like
- BetMGM has a real sister site family through LeoVegas Gaming PLC, not just vague corporate connections.
- The UKGC record is clean, with no regulatory actions listed for account 39198.
- The casino welcome offer is better than it first sounds because the free spins and winnings are wager-free once unlocked.
- The payment table is clear on method limits.
- The brand has a proper identity, even if the Vegas act won’t be to everyone’s taste.
What I don’t
- The MGM name can make the UK structure feel simpler than it is, because the licence holder is LeoVegas Gaming PLC.
- The casino’s qualifying rules for bonuses include many exceptions to game contributions.
- There’s no general support phone number.
- Some players will find the Las Vegas branding fun; others will find it overcooked.
- The inactive domains on the UKGC record add historical clutter but no current value.
My final verdict on BetMGM and its sister sites
BetMGM is one of the few gambling brands where the branding may be louder than the story of its network and the network story is still pretty interesting. The practical answer is simple: BetMGM’s useful sister sites are LeoVegas, BetUK, Pink Casino, SlotBoss and 21.co.uk. If I wanted the closest all-around move, I’d choose LeoVegas. If I wanted sport, I’d choose BetUK. But if the whole Vegas spectacle is exactly what pulled you in, none of the sister sites quite replaces BetMGM itself.
