Compare all 5Pros
- The only welcome offer in the group aimed at live dealer tables rather than slots
- Live Casino leads the navigation, so the product on offer is the product shown first
- £10 minimum deposit, half what Slot Boss asks
Cons
- The offer card says the chips work on any live casino game; its own small print limits them to eligible Playtech games
- £5 in chips is a quarter of the £20 in spins BetMGM gives for the same £10 deposit
- Golden Chips expire three days after they are credited

About 21.co.uk
21.co.uk is one of six UK brands operated by LeoVegas Gaming plc, which MGM Resorts International acquired in 2022. It offers casino and live casino. Launched 2013; sportsbook discontinued in 2023, leaving casino and live casino.
One live-casino welcome offer plus three ongoing promotions. Live Casino leads the navigation. The welcome offer is £5 in golden chips on live from las vegas tables for a £10 deposit, with 1x wagering and no wagering on the winnings themselves.
21.co.uk is the only brand in this group built around live dealer tables rather than slots, and it shows on the first screen. Captured on 8 August 2026, its navigation reads Live Casino before Casino, the homepage background is a wall of live-dealer tables, and the welcome tile reads 'GET £5 IN GOLDEN CHIPS WHEN YOU STAKE £10 ON LIVE CASINO'.
Read the offer card on its promotions page closely, because its two halves disagree. The headline copy says the chips are '50 x £0.10 Golden Chips to use on any Live Casino game'. The small print beneath it says the £5 in Golden Chips is 'to use on eligible Playtech games', after depositing £10 or more within seven days of registering and wagering it once on live casino within seven days, with a three-day expiry. The small print is the binding version: these are not chips you can take to any live table on the site.
Beside that one available promotion the page lists three ongoing ones, headed by the same Gigantic Jackpots pool its sister sites advertise as 'over £42 million'.
No payments page was found for 21.co.uk during this review — the capture of it returned a 404 page headed 'NOTHING TO SEE HERE'. Slot Boss and BetUK publish their withdrawal holds on pages quoted on their own reviews; for 21.co.uk no equivalent is quoted here, so check withdrawal terms before depositing rather than after.

Withdrawals cleared in 5 to 15 minutes when checked by our own team in August 2026. That is fast by any standard in this market — for comparison, the fastest published windows elsewhere on this site are BetMGM's and Pink Casino's at one to three days. Not scored higher because speed was the only input recorded: no logged-in cashier method list, no minimum, maximum or fee schedule, and no note of what identity verification asked for or at what point. The figure is a portfolio-level result rather than a per-brand timing, so every brand it covers carries the same score. (2 sources)

21.co.uk pros and cons
Pros
- The only welcome offer in the group aimed at live dealer tables rather than slots
- Live Casino leads the navigation, so the product on offer is the product shown first
- £10 minimum deposit, half what Slot Boss asks
Cons
- The offer card says the chips work on any live casino game; its own small print limits them to eligible Playtech games
- £5 in chips is a quarter of the £20 in spins BetMGM gives for the same £10 deposit
- Golden Chips expire three days after they are credited
- No payments page was found where its sister sites publish theirs
What 21.co.uk lacks
- No sportsbook
Common complaints about 21.co.uk
Withdrawals held for verification
commonEvery brand in this group states that withdrawals are reviewed before release, and that a KYC check may be required first. On BetUK the hold is explicitly 24 hours before a further 3–5 working days. This is standard UKGC practice rather than an operator failing, but it is the single most common source of surprise for new players expecting an instant payout.
Group payment terms, read across sibling brands
One payment method at a time
occasionalPlayers cannot switch payment method while their balance is £10 or more, and withdrawals must return to the method used to deposit. Both rules are anti-money-laundering requirements applied group-wide, but they catch out anyone who deposits by card intending to withdraw elsewhere.
Group payment terms, worded identically across brands
21.co.uk Sister Sites — the verdict
21.co.uk is the one brand in this group that is not a reskin, and for a live-casino player that makes it the natural way in: the welcome is £5 in chips for live tables rather than spins on a slot, and the site leads with live dealers. The catch is on the offer card itself, which promises chips for 'any Live Casino game' in its headline and limits them to eligible Playtech games in its small print. Believe the small print. And with no payments page found where its siblings keep theirs, check the withdrawal terms before your first deposit.

21.co.uk sister sites — FAQ
Who owns 21.co.uk?
21.co.uk is operated by LeoVegas Gaming plc under UK Gambling Commission account 39198, alongside LeoVegas, BetMGM, BetUK, Pink Casino, Slot Boss and 21.co.uk. LeoVegas Gaming plc has been owned by MGM Resorts International since 2022.
Is 21.co.uk on GamStop?
Yes. 21.co.uk holds a UK Gambling Commission licence, and every UKGC licensee must integrate with GamStop. Self-excluding through GamStop blocks every GB-licensed gambling site, including all six brands in this group.
Can I claim a welcome bonus at every one of the 21.co.uk sister sites?
Each brand advertises its own welcome offer, and LeoVegas Gaming plc publishes no rule on claiming more than one. One welcome per customer across a licensee is the usual assumption, so treat a second as unlikely rather than assured and check the terms before depositing at another brand.
How many 21.co.uk Casino sister sites are there?
The 21.co.uk Casino sister sites are the other brands operated by LeoVegas Gaming plc under the same UK Gambling Commission account 39198 — LeoVegas, BetMGM, BetUK, Pink Casino, Slot Boss and 21.co.uk, minus 21.co.uk itself. Every one is listed and compared in the table above, with the evidence for each relationship set out beneath it.
Can 21.co.uk's Golden Chips be used on any live casino game?
No, despite what the headline of the offer suggests. The promotions page describes '50 x £0.10 Golden Chips to use on any Live Casino game', but the small print on the same card says the £5 in Golden Chips is to be used on eligible Playtech games, credited after a £10 deposit is wagered once on live casino, with a three-day expiry. Where two parts of an offer disagree, the small print is the version the terms enforce.
How is 21.co.uk different from its sister sites?
It is the only brand of the six run by LeoVegas Gaming plc under UKGC account 39198 that leads with live casino: Live Casino comes first in its navigation and its welcome offer is £5 in Golden Chips for live tables rather than free spins on Big Bass Splash. LeoVegas, BetUK and Pink Casino give 50 spins for £10, BetMGM 200 spins for £10 and Slot Boss 50 spins for £20.
