21 Casino is another brand from the powerhouse that is White Hat Gaming - you can be certain that every new casino that WHG launches will have all the tools at its disposal to create one of the UK’s best online casinos.  

21 Casino Welcome Bonus 

From the off, new players can take up the 121% non-sticky Welcome Bonus of up to £300 on their first deposit - that’s a very generous 21% over the industry standard of 100%. You do have to opt into the promotion and your account needs to be verified. However, this is usually done electronically upon registration, so you shouldn’t have to do anything manually.   
Always ensure you read the full terms and conditions before accepting a bonus. Here are the most significant: 

  • Available to UK players aged 18+
  • The minimum deposit to claim the bonus is £10
  • The maximum bonus awarded is £300
  • Bonus funds need to be wagered 35x before withdrawal
  • The original deposit and any winnings can be withdrawn at any time, but the bonus must be forfeited
  • The maximum bet while using bonus funds is £5
  • Unused bonus funds will expire after 30 days
  • Various game weighting contributions apply
  • Please gamble responsibly

21 Casino No Deposit Bonus Code 

We didn’t find any no deposit bonuses or 21 casino bonus code promotions for players at the time of writing, which we have to admit is disappointing. However, if you've opted in to receiving marketing emails and SMS, you will certainly be notified of any coming up (especially if you don’t play for a little while).

White Hat Gaming have launched a number of very successful casinos since 2014, so 21 Casino was already set up for success from the start, and in fact, they’ve already established themselves as one of the best slot sites with great customer feedback.
21 Casino is licensed by the UK Gambling Commission which means players can be assured of a safe and secure gaming experience.  

Bigger than average welcome bonus
Absolutely HUGE selection of games
Excellent Live Dealer Casino
No ongoing promotions for existing UK customers

You’ll find a great selection of over 50 titles under the Table Games tab including popular games from the best casino software providers such as Inspired Gaming and NetEnt, plus a few of the more unknown studios like Switch, Felt, Seven Deuce and Iron Dog.

The Other Games tab offers over 30 scratch cards including the game show-themed Deal or No Deal from Endemol, Fishin Frenzy from Merkur, Keno Pop from 1x2 Gaming and Koi Cash from Hacksaw Gaming. 
All game tiles display the game provider and volatility level upon hover - the volatility index is something we really like as it enables you to quickly dismiss a game if it’s too volatile. You might prefer to enjoy your gameplay with regular wins instead of adopting an all-or-nothing approach. 
All RNG games are tested by a leading laboratory for fairness and their payouts are audited to ensure they remain within expected values.

21 Casino Live Casino 

The 21 Casino Live Casino lobby features nearly 40 games from the two largest live dealer providers, Evolution and Pragmatic Play Live. But there are a lot more titles available if you visit Evolution or Pragmatic Play’s main lobbies - roulette, blackjack, baccarat and game shows. All the best live casinos will feature Evolution games and we’d be concerned if they didn’t. 
You will find plenty of classic roulette and blackjack tables available - and also some with unique twists such as Speed Blackjack, Instant Roulette and the Cash or Crash type games that are becoming very popular lately, especially with streamers, due to their highly volatile nature and potential for very big wins.

21 Casino User Experience 

The 21 Casino site works flawlessly across all devices as expected. Each page is fully responsive and will adapt to every device specification - whether it’s an ultra-wide, standard or reduced size screen monitor that you’ll find on a notebook - the site looks and performs great.  
The 21 Casino site is logically structured with all games classified into categories of New, Top, Live, Table, Jackpot and Other Games. You have the option to save games into your Favourites category and Last Played Games will give you an additional route back to your favourites.  
A Top Providers category displays a list of all games available from your chosen provider, which is handy when you have a preference for a particular presentation or game mechanic and want to see if there are any similar games from that provider.  
A Search tool very cleverly offers up a Popular Tags option which is a shortcut to popular or trending searches such as ‘Cluster Pays’ or ‘Avalanching Wins’. This suggests games are categorised by more attributes than are visible to the player on the front end.  

21 Casino Mobile Casino 

Navigating and playing on mobile is via a device's browser as 21 Casino is a fully responsive website, like many of the casino apps
Playing on a mobile or tablet offers exactly the same user experience with no degradation of quality. Naturally, the reduced screen size results in fewer games being displayed in the lobby at any one time, but this is to be expected.  

Deposit and Withdrawal Methods Available at 21 Casino 

There is an abundance of deposit methods available at 21 Casino - in fact, more than most UK casinos we’ve come across. The minimum for both deposits and withdrawals is just £10 with no processing fees on either. 

  • Visa and MasterCard (debit card only) 
  • PayPal 
  • Instant Bank Transfer and Instant Bank Payment 
  • Neosurf 
  • paysafecard 
  • CashToCode 
  • Skrill 
  • Neteller 
  • Maestro 
  • UPI 
  • NetBanking 

Withdrawals are usually processed within 48 hours and need to go back to the same method as deposit. 
If you’ve not been electronically verified upon registration, you are more than likely going to be required to submit identity and proof of address documents before making a withdrawal. This is common practice in the UK and required by the licensing authority to help combat fraud, including money laundering, and to protect vulnerable or underage players. 
It’s always good practice to keep digital copies of your documents available to ensure your withdrawals aren’t delayed in being processed.

21 Casino Slots

Whether you prefer classics such as Starburst, Book of Dead, Jammin’ Jars and Reactoonz, or are a fan of the latest Meagways titles such as Temple Tumble, Buffalo King and Eye of Horus,  you’ll be hard-pressed to NOT find a slot you’re looking for at 21 Casino.

The largest-ever Progressive Jackpot was in fact won on Absolootly Mad™ Mega Moolah in April 2021 - a staggering £16.3m (€19.4m).

21 Casino RTP & Payout Rates 

21 Casino has decent payouts with hundreds of slots offering an above-average return to player rate.  

21 Casino Software Providers 

As 21 Casino is built and managed on the industry leading White Hat Gaming platform, they have access to all the best casino software providers such as NetEnt and Evolution. This enables a huge inventory of games available for their players - something that less established operators will struggle to achieve as it’s often a very costly integration. 
Evolution is by far the largest live dealer casino provider and any site worth its salt should be able to offer you their games.  
NetEnt  are the one of the most established slot providers still in existence. Although they’re fighting off stiff competition from the indie slot studios, they still have a massive cult following with classics such as Starburst.

21 Casino Loyalty Scheme 

21 Casino’s loyalty scheme was based on collecting Royal Loyalty Points, with every 200 points earned resulting in a £1 bonus. This loyalty scheme was unfortunately stopped after October 2021 although customers could still redeem their existing points. There appears to be no replacement 21 casino loyalty scheme as of May 2022.    

Responsible Gambling Features at 21 Casino 

As an online casino licensed by the UK Gambling Commission, 21 Casino are fully committed to providing a comprehensive Responsible Gambling policy.

Additional tools are available for the player, including 

  • Deposit Limits - daily, weekly or monthly limits
  • Game Time Reminder - as low as 1 minute to whatever you desire
  • Time Out/take a break - from 24 hours to 6 weeks
  • Self Exclusion/account closure - account closure can be reversed but Self Exclusion is permanent
  • Access to Account History - this helps understand how much you might be spending

The Responsible Gambling Policy can be found in every page’s footer and also in My Account. You can find a wealth of information including a self-assessment with links to organisations that can offer help. 
21 Casino and WHG make annual donations to BeGambleAware in support of problem gamblers.

Our Verdict 

21 Casino being a White Hat Gaming brand is worthy of signing up for. The enormous selection of games plus a well-stocked Live Dealer Casino should be enough to justify that choice, but 21 Casino also offers a 121% Welcome Bonus of up to £300 to help get you started. 
Fully licensed by the UK Gambling Commission and a robust Responsible Gambling Policy ensures players are well protected and their funds secure. 
The only slight negative we can find with 21 Casino is that there are no ongoing promotions for existing players.  But if this isn’t your main priority and you’re more than happy with a 121% Welcome Bonus of up to £300, then it’s a no-brainer.
