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.
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:
We didn’t find any no deposit bonuses or 21 casino bonus code promotions for players at the time of writing this review, 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).
|📅 Online Since:||2014|
|🎁 Welcome bonus||121% Welcome Bonus up to £300|
|⚖️ Gambling Authority||UK Gambling Commission|
|💻 Casino Software:||NetEnt, IGT, Play’n GO & More|
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.
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.
|Roulette x5||Golden Rock Studios|
|Fortune Pai Gow Poker||Shuffle Master|
|Hold ‘Em Switch||Seven Deuce Gaming|
|European Roulette Gold Series||Microgaming|
|Vegas Strip Blackjack||Switch Studios|
|20p Roulette||Inspired Gaming|
|100 Bit Dice||4 The Player|
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.
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.
|Lightning Roulette||£0.20 - £10,000|
|Immersive Roulette||£1 - £10,000|
|Blackjack Party||£0.50 - £200|
|Blackjack Grand VIP||£500 - £10,000|
|Dragon Tiger||£1 - £15,000|
|Super Sic Bo||£0.20 - £2,500|
|Peek Baccarat||£1 - £5,000|
|Super Andar Bahar||£0.50 - £2,500|
|Crazy Time||£0.10 - £1,000|
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.
Navigating and playing on mobile is via a device's browser as 21 Casino is a fully responsive website, like many of the best mobile casino sites.
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.
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.
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.
Now this is where it really becomes interesting! 21 Casino offers a huge selection of the latest slots to enjoy - in fact, over 2,000 top titles from over 90 game providers. Having so many suppliers is proof of how much providers desire to work with White Hat Gaming casinos.
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.
|Game Title||Game Provider|
|Danger High Voltage||Big Time Gaming|
|Big Bass Bonanza||Pragmatic Play|
|Legacy of Dead||Play’n GO|
|Tombstone RIP||No Limit City|
|Jammin’ Jars||Push Gaming|
|The Goonies Return||Blueprint|
If jackpot slots are your thing, you’ll be pleased to hear that 21 Casino offers over 80 including Jackpot King and Mega Moolah progressive jackpots where life-changing sums or 7 or 8 figures can drop at any time. The largest-ever Progressive Jackpot was in fact won on Absolootly Mad™ Mega Moolah in April 2021 - a staggering £16.3m (€19.4m).
|Jackpot Slot||Jackpot Pool & Provider|
|Divine Fortune Megaways||NetEnt|
|Gold Strike Bonanza||Jackpot King/Merkur|
|Wolf Gold||Drops & Wins/Pragmatic Play|
|Absolootly Mad||Mega Moolah/Microgaming|
|Thundering Buffalo||Jackpot Dash/High 5 Games|
21 Casino has decent payouts with hundreds of slots offering an above-average return to player rate.
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, Microgaming 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 and Microgaming are the two most established slot providers still in existence and between them, they used to dominate every casino lobby. Although they’re fighting off stiff competition from the indie slot studios, they still have a massive cult following with classics such as Starburst, Gonzo’s Quest and Immortal Romance.
The signup process at 21 Casino is straightforward and only essential information is required to get you up and running within a minute:
You will be required to verify your account in Step 3, so ensure you provide the correct contact details!
You are usually electronically verified upon registration and this will enable you to deposit and start playing immediately (it also assists with speedier withdrawals).
The quickest way to get help is to contact Live Chat support agents who are available 24 hours a day. As 21 Casino Live Chat support is handled by White Hat Gaming, there are plenty of agents available with virtually no waiting time.
Our requests for assistance were met by a professional and helpful agent who resolved our queries in no time.
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.
As an online casino licensed by the UK Gambling Commission, 21 Casino are fully committed to providing a comprehensive Responsible Gambling policy. This includes suggesting new customers set a deposit limit immediately upon registration and providing session reminders for players to keep track of how long they’ve been playing.
Additional tools are available for the player, including
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.
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.
