4.1/5

A polished LeoVegas-run casino with a big live lobby and its own Gigantic Jackpots, though the welcome offer is small and short-lived.

21.co.uk review: overview

Our 21.co.uk review looks at a casino that has been around since 2017. Its name nods to blackjack. Today, however, it offers a full mix of slots, jackpots and live tables.

LeoVegas Gaming PLC runs the site, and it also runs LeoVegas, BetMGM UK and Pink Casino. The US group MGM Resorts owns LeoVegas. As a result, 21.co.uk carries several MGM-themed exclusive games.

LeoVegas Gaming PLC holds UK Gambling Commission account 39198, and the register lists 21.co.uk as an active domain. You can check this yourself on the Gambling Commission public register. When we checked, the register showed no regulatory actions against this licence.

In this 21.co.uk review we look at the welcome offer, games, payments, apps and safer gambling. If any terms are new to you, our glossary of betting and gambling terms can help.

Welcome offer

New customers can get £5 in Golden Chips. First, you opt in and deposit at least £10 within 7 days of signing up. Then you wager that amount once on any live casino game, also within 7 days.

Once you meet those steps, you receive £5 in Golden Chips. These are a type of bonus chip for eligible Playtech live tables. However, they expire after 3 days, so you need to use them quickly.

There are a few other catches. Wagering contributions vary by game, and some exclusions apply. In addition, the offer suits live casino fans only, because slots don’t count towards the qualifying wager.

For this 21.co.uk review, we rate the offer as modest. It is simple and the 1x wagering step is low. That said, £5 is a small reward, and the short expiry leaves little room. As always, only deposit what you are happy to spend.

Games and software

Gambling.com counts more than 2,500 casino games at 21.co.uk. Slots make up most of the range, from classic fruit machines to Megaways and Slingo. There are also instant wins, crash and mines games, bingo and table games.

The lobby has handy sections for new games, classic slots and 21.co.uk exclusives. In addition, a separate jackpots tab gathers the progressive games in one place. So it is easy to browse even with such a large range.

Jackpots are a real strength here. The in-house Gigantic Jackpots network has four tiers, and it also runs on some live tables. In addition, you’ll find big networks such as Mega Moolah, Age of the Gods, WowPot and Jackpot King.

The live casino is large too, with 200+ tables. Studios include Evolution, Playtech, Pragmatic Play Live, Ezugi and OnAir Entertainment. For example, there are exclusive tables and game shows alongside standard blackjack and roulette.

Meanwhile, MGM-themed exclusives such as Bellagio Diamonds, MGM Grand Gamble and Mysteries of Luxor add something different. In our 21.co.uk review, these exclusives and the jackpot range stood out most. If you’d like to try games without spending, our free online casino games page is a good place to practise.

Payments and withdrawals

21.co.uk keeps its banking fairly simple. Independent reviews and the site itself list these options:

  • Visa and Mastercard debit cards
  • PayPal
  • Apple Pay
  • Instant bank transfer

Gambling.com reports that e-wallet withdrawals usually go through within 24 hours. However, card and bank transfer payouts can take up to five working days. We could not confirm a minimum withdrawal or any fees, so check the cashier before you deposit.

Overall, the 21.co.uk review score for payments is fair rather than high. PayPal and Apple Pay are handy, but there are no other e-wallets such as Skrill.

You’ll also need to verify your identity before your first withdrawal. So it helps to upload your documents early, because this avoids delays later. Our guide to online casino basics explains how these checks work.

App and mobile experience

21.co.uk has apps for both iPhone and Android, and you can also play in a mobile browser. The iOS app holds a rating of around 4.3 stars. In contrast, the Android app sits nearer 3.6, based on far more reviews.

The layout is clean, with clear tabs for slots, jackpots and live casino. In addition, the search tool makes it easy to find a game by name. Most of the game library, including live tables, is available on mobile. However, live streams work best on a steady Wi-Fi or 4G connection.

Overall, the mobile side is solid. Most players will find the browser version works just as well if they’d rather not download an app. That said, the app makes it quicker to log in and set limits on the go.

Safer gambling and customer support

21.co.uk offers a full set of safer gambling tools. For example, you can set deposit, loss and wagering limits, plus session limits and reality checks. You can also take a time-out or self-exclude, and the site supports GAMSTOP.

Support is available 24/7 by live chat, which is better than many rivals. There is also an email address and a help centre for common questions. Meanwhile, links to BeGambleAware and GamCare appear across the site.

Remember that gambling is for over-18s only. If it stops being fun, use the tools above or call the National Gambling Helpline on 0808 8020 133.

Our verdict

21.co.uk is a well-run casino from a large, established group. Its jackpots, exclusive games and big live lobby give it real character. Similarly, 24/7 live chat and strong safer gambling tools add to the appeal.

21.co.uk has sister sites. LeoVegas Gaming PLC also runs Pink Casino and Slot Boss, all under the same UKGC licence. So if you like how 21.co.uk works, those sites are worth comparing. However, each one has its own welcome offer and terms.

However, the welcome offer is small, and card withdrawals can be slow. Ongoing promotions also seem limited, and the VIP scheme is invite-only, according to Gambling.com. Overall, this 21.co.uk review finds a solid choice for live casino and jackpot fans who don’t mind a modest bonus. Compare it with other brands in our casino reviews or browse the latest casino offers.

21.co.uk review: the casino at a glance

In short, our 21.co.uk review finds a stylish LeoVegas casino with a strong live lobby and exclusive jackpots. Support is available around the clock. However, the £5 welcome offer is small and expires quickly.
