LeoVegas Sister Sites: 5 Brands, 1 Costly Trap (2026)

The leovegas sister sites are BetMGM, Bet UK, 21 Casino, Pink Casino and Slot Boss. All five sit on one account with LeoVegas itself. The trap is Slot Boss: it asks for a £20 deposit to hand you the same 50 wager-free spins, on the same slot, that LeoVegas and Pink Casino give for £10.

18+. T&Cs apply. Support is at GamCare.

All six brands compared

Four of the six run what is recognisably one offer: 50 spins, one slot, 1x wagering, a seven-day window. What changes is the price of entry.

The £20 question

Put the three identical offers side by side and the problem is obvious.

LeoVegas: £10 for 50 wager-free spins on Big Bass Splash. Pink Casino: £10 for 50 wager-free spins on Big Bass Splash. Slot Boss: £20 for 50 wager-free spins on Big Bass Splash.

Same company, same game, same wagering condition, same expiry window. Twice the deposit.

There is no published compensation for the extra tenner, no larger spin value, no extra spins, and no better terms attached to the offer. If you were going to join Slot Boss for that welcome offer, the same offer is available next door for half the money.

That single comparison is the most useful thing on this page, and it is only visible because these brands sit on one account and can be read side by side.

The best LeoVegas sister sites

Pink Casino, the same offer at the lowest price. 50 wager-free spins for £10 with 1x wagering. Identical to LeoVegas’s own offer, so pick on which site you prefer rather than on value.

Bet UK, best if you bet on sport as well. It is the only brand of the six pairing the casino spins with a sports offer, at £40 in free bets for a £10 qualifying bet, paid as four separate £10 bets rather than one.

21 Casino, the only one that is genuinely different. £5 in Golden Chips for a £10 live-casino stake, playable on eligible Playtech games. It is the only brand here whose welcome offer targets live casino rather than slots.

Slot Boss is the one to skip unless something other than the welcome offer draws you to it.

LeoVegas sister sites no deposit bonus

None of the six brands published a no-deposit offer on the pages read on 15 August 2026. Every welcome offer among the leovegas sister sites requires a deposit first, £10 at four of them and £20 at Slot Boss.

The closest thing to low-risk here is the wager-free structure rather than the deposit. At LeoVegas, Pink Casino and Slot Boss the spin winnings carry no wagering requirement, which means what the spins win is yours rather than something you must play through.

18+. New customers only. Opt in required. Deposit and 1x wagering conditions apply within 7 days. Further T&Cs apply.

Wager-free is the thing worth having here

Most groups covered on this site attach a multiple to spin winnings, and it is where the real cost hides. This group mostly does not.

LeoVegas, Pink Casino and Slot Boss all describe their spins as wager-free. The 1x condition in their terms applies to the qualifying deposit, not to what the spins win. That is a meaningfully better structure than a 10x or 30x requirement on winnings, and how wagering requirements work sets out why the difference is larger than it sounds.

Bet UK states 50 free spins for £10 played on the same 1x qualifying basis, without using the wager-free wording for the spins themselves.

21 Casino’s Golden Chips are a bonus credit rather than spins, so they behave differently again and should be read on their own terms.

The sports and live-casino corners of the group

Two of the six break the slots pattern, and they are the reason to look past LeoVegas itself.

Bet UK is the only brand pairing a casino offer with a sportsbook one. Its sports welcome offer is £40 in free bets for a £10 qualifying bet placed within seven days, and the structure matters: it pays as four separate £10 bets rather than one £40 stake, split between football accumulators of four or more selections and sports multiples of two or more. The free bets last seven days.

That split is a real constraint. Four tenners across specific bet types is a narrower thing than £40 to use as you like, and free bets return winnings only rather than the stake.

21 Casino is the other outlier, and the only brand in the group whose welcome offer points at live casino rather than slots. Its £5 in Golden Chips arrives for a £10 live-casino stake and is playable on eligible Playtech games, which also tells you which supplier sits behind its live tables.

Neither offer is directly comparable with the 50-spin template, which is the point: if you want sport or live dealer, the leovegas sister sites give you exactly one option each.

Are they actually different?

Underneath, no. Three things give it away, and all three are visible without an account.

Every one of the five readable brands advertises the same jackpot pool at the same moment. That is one shared jackpot network across the leovegas sister sites, not five separate ones.

Four of them build their welcome offer on the same slot, Big Bass Splash, with the same 1x condition and the same seven-day windows.

The navigation is the same on all five, down to the ordering of the menus and the wording of the safer-gambling and support links.

The jackpot figure is the most striking of the three. Read within the same hour, LeoVegas quoted £42,438,834 while its siblings advertised the same pool as “over £42 million”, one pot, displayed with different precision depending on the brand.

Above that, the differences are presentational. Pink Casino is aimed at a different audience from Slot Boss, and 21 Casino leads on live casino with Playtech content. But the platform, the jackpot pool and the offer template are shared, so switching between them changes very little about what you are actually playing.

What carries over, and what doesn’t

A group with no registered trading names

One detail separates this group from most on the register.

LeoVegas Gaming PLC has no trading names registered against its account at all. Six brands trade on it, and not one of them is filed as a name. Every brand appears by web address only.

That is legal and not unusual for a platform-led group, but it has a practical effect: searching the register by brand name returns nothing for Pink Casino, Slot Boss, Bet UK or 21 Casino. You have to search by domain to find them, which is precisely why affiliate lists miss the connection.

It is also why this group is harder to verify than one like Betfair’s, where the names are filed and the account tells you plainly what belongs to whom.

Drawbacks and gaps

Slot Boss charges twice the deposit for an offer its siblings give for £10, and publishes nothing to justify it.

BetMGM’s UK site returned a bot-protection page instead of content, so the biggest name in the group is the one a reader can learn least about before registering.

leovegas.com is filed inactive on the account while leovegas.co.uk is active, so an old bookmark pointing at the .com address is no longer the UK site.

None of the six publishes a game count on the pages read, so there is no way to compare library size before signing up.

If you self-excluded on one, are you blocked on the rest?

Yes, on all six. One company holds the account, so a self-exclusion applied with LeoVegas covers BetMGM, Bet UK, 21 Casino, Pink Casino and Slot Boss too.

All six are licensed in Great Britain and take part in GAMSTOP. One registration at GAMSTOP blocks the whole group along with every other operator licensed to serve Great Britain.

Because the brands here look so different from one another, a pink-branded casino, a sportsbook, a live-casino site, it is worth being explicit: they are one operator, and treating them as separate places to play is the mistake this page exists to prevent.

GamCare runs the National Gambling Helpline free on 0808 8020 133, at any hour.

If a payout goes wrong

Complaints go to the brand first, and because one company holds all six, escalating from Slot Boss to LeoVegas reaches the same complaints team rather than a fresh one.

An unresolved dispute then goes to an independent adjudicator rather than to the regulator, which does not rule on individual cases. IBAS handles gambling disputes for operators inside the British system, and every brand here falls inside it.

Which LeoVegas sister site should you pick?

Pink Casino or LeoVegas, on identical terms: 50 wager-free spins for £10. Choose on which site you would rather use, because on value there is nothing between them.

Take Bet UK if you want a sports offer alongside the spins, since its £40 in free bets is the only sports component in the group. Take 21 Casino if live casino is what you came for.

Do not take Slot Boss for the welcome offer. For groups where the account boundary rather than the price is the thing to watch, 888’s account and Betfair’s family are the comparisons, and what sister sites actually means covers why one company can trade under six names.

Who runs these sites

LeoVegas, BetMGM, Bet UK, 21 Casino, Pink Casino and Slot Boss all trade on Gambling Commission account 39198, held by LeoVegas Gaming PLC. Six web addresses are active on that account, five more are inactive, and no trading names are registered against it at all.

Eleven addresses are filed in total: the six live ones, the two leovegas.com addresses marked inactive while leovegas.co.uk stays active, and three retired bingo sites, Bingo Godz, Bingo Loopy and Bingos. Those three are not sister sites you can join; they are names the group no longer trades under.

All of it is checkable on the public register, read on 15 August 2026.

If gambling stops being fun, GamCare and GAMSTOP are both free.
