Wagering Requirements


If you have signed up for a new account, you can claim a one-time welcome bonus. Simply opt-in when making your first deposit, which must be at least £10. The casino will match your deposit 121% up to a maximum of £100 worth of bonus money.

Claiming Your Welcome Bonus

  • Deposit £10, 121% = £22.10 starting balance
  • £12.10 bonus balance & £10 real money balance
  • Maximum is £100 worth of bonus money
  • Convert the bonus into real money by meeting the 35x wagering requirement
  • £5 maximum spin bet or betting round using bonus money
  • Bonus expires after 30 days

As welcome bonuses go, we think this is a pretty generous bonus, with up to £100 on offer.

You must verify your account before claiming the bonus, with additional documents needed if requested.

Wagering Requirements

To convert your bonus balance into real money, you must play through 35x worth of wagering requirements. An example of this playthrough is as follows:

  • If you deposit £10, you will receive a bonus of 121% of your deposit.
  • Your total bonus balance will be £12.10.
  • You will need to wager a total of £12.10 x 35 = £423.50.

Another important point to understand, bets using real money do not count toward wagering. Bonus funds will be used ahead of any real money in your account, and it’s at this point your bonus bets will count toward the wagering requirement.

However, you should also note that bets on some games do not contribute 100%. Check out the game requirements and which have the highest contribution percentages.

  • 100% – Video Slots, Scratchcards and Keno
  • 20% – Slot Games in promo T&Cs section 5.5
  • 10% – Table Games
  • 5% – Video Poker
  • 0% – Live Casino & Progressive Jackpots
  • 0% – Slot Games in promo T&Cs section 5.5

We’d like to see 21 Casino introduce more games with higher contribution rates, but this is a standard aspect amongst online casino bonuses.

Our Thoughts on This Bonus
Whilst we understand the 121% deposit-match offer fits with the casino's name, but it does confuse us. The wagering requirements attached are fairly standard with limited games for the playthrough requirements. Some free spins on top of the deposit match would be nice, but this is a decent welcome bonus for new online casino players.

21 Casino Lobby Explained

21 Casino comes with a sleek and modern look. It uses a dark colour scheme, with a black background and a gold logo that has a royalty look and feel. At the top of the homepage, a slider showcases the site's welcome bonus and boasts access to responsible gambling tools.

Running horizontally at the top is the menu area. Here you will find log-in and registration, as well as games and promotions. Once you sign in, the log-in area changes to display your real money balance, available bonuses, and deposit button (cashier area). Also, the menu area will add My 21, account, and messages alongside the games and promotions options.

As you scroll down the homepage, it divides into several sections, such as video slots and live casino with each showing clickable thumbnails for games. It's very easy to understand, but remains effortlessly classy to keep with their stellar image.

21 Casino Games


The bread and butter of any online casino, 21 Casino's game selection is very strong and will no doubt appeal to players of all tastes. A comprehensive slots catalogue makes up for the majority of their game collection, but is backed up by a respectable live casino.

Best 21 Casino Slots

There are 1,500+ online slot titles coming from close to 100 developers, and these numbers continue to grow. As such, you can expect at least 50 fresh releases per month featured in the new games lobby which updates almost daily. All these games have a demo mode so you can test the theme and the features are up to scratch before committing real money.

To find specific video slot titles, there is a search bar, which comes with tags such as Cluster Pays and Avalanche/Cascading Wins, and an option to filter games by provider. Then for the full selection, there’s a Slot Games section.

Here you can filter games by Megaways, Cluster Pays, Mega Symbol (3x3), and Sticky Wilds. This is a great add-on, but perhaps 21 Casino could add a number of additional filters. Themes, respins, multipliers and more popular filter options we see available in competing UK online casinos would make a big improvement.

If you are looking for sizable drop-in wins, there is a dedicated Jackpot Slot lobby. Here, 21 Casino combines Mega Jackpots, Jackpot King, Mega Moolah, and WowPot jackpot networks giving you a shot at hitting a jackpot win.

Our Thoughts on 21 Casino Slots
Overall, the 21 Casino video slot portfolio oozes quality. The only catch for some players is that compared to some of its competitors the volume of games is low. However, this is done on purpose. By refining its games library, the casino cuts out the noise leaving high-quality game titles in your path.

21 Casino Live Casino Games

21 Casino have partnered with industry heavyweights Evolution Gaming and Pragmatic Play Live to offer their players top quality live dealer games. However, there is no getting away from the fact that they are lacking quantity, with just 40+ live casino games currently available on-site.

There is a nice variation here, with all the special games you would expect, as well as a healthy dose of Live Game Show games, including Crazy Time, Monopoly Live and Sweet Bonanza Candyland.

Our thoughts on 21 Casino Live Casino
This is a solid live casino offering, but the lack of quantity is a genuine concern - we worry you will struggle to find a seat at a Live Blackjack table at busier times. To put their 40 games into context, many other online casinos offer 100+ titles, with some offering as many as 200+. There's plenty of quality here, but we're lacking the quantity.

21 Casino Table Games

The 21 Casino Table Games section will mostly suit roulette and blackjack players, but there are also some poker tables, video poker and baccarat titles available. 20p Roulette is perfect for those looking for low-stakes bets, while Roulette Mega Moolah is an exciting jackpot version of the casino classic.

As for blackjack, there is a wealth of variations to choose from, including Atlantic City Gold Series, Perfect Pairs, Vegas Downtown.

Evolution Gaming’s First Person 3D rendering games may also pique your interest. Its collection features Mega Ball, Dream Catcher, Football Studio and Deal or No Deal game show titles, plus baccarat, roulette, lightning roulette, craps, and blackjack.

To top off this section, the casino also includes fun titles like 100 Bit Dice, DJ Wild, Casino Solitaire, Casino War, and Who Wants to be a Millionaire.

Software Providers

With 100+ game developers, you are in great hands. With so many developers on their website, it is safe to assume they have all bases covered - if there’s an obvious developer omission, we couldn’t find it! Big-hitters like Evolution Gaming, Pragmatic Play and Microgaming all feature prominently, with new titles being released all the time.

21 Casino Licenses

One way to tell if an online casino is legitimate, safe and trustworthy is by looking into its licensing. Well, 21 Casino passes with flying colours boasting a number of licences that allow the platform to offer its services to players across the globe.

21 Casino Mobile Casino


Mobile access to 21 Casino is available via any HTML5 internet browser. The most popular ones in the UK are Chrome, Edge, and Safari, but your device’s built-in/own-brand browser should suffice. Don't worry, you are still able to enjoy all the features of 21 Casino from your mobile device.

Some of you may be disappointed to learn that the casino does not offer an official mobile app. Yet, there is an amicable workaround. There is an app extension you can download to mobile/desktop browsers allowing for quick access to 21 Casino.

Meanwhile, adding a casino app is something the casino will need to work on as many of its UK competitors already offer this additional feature.

Whether you are a high roller or not, the 21 Casino Level Up Loyalty Program lays out the red carpet by offering a simple way to earn VIP rewards. Every time you make a cash bet, a level bar will increase. As you complete each level, the casino will instantly reward you.

All you need to do is head over to the ‘My Rewards’ area to find out what it is. Stay braced, because it could be Bonus Spins, Super Bonus Spins, Mega Bonus Spins, Ultra Bonus Spins or Bonus Funds. On top of this, you will receive a surprise gift.

Compared to other loyalty reward programs, 21 Casino’s Level Up system is a breath of fresh air. Rather than collecting points to traverse levels, the progress bar makes things feel a little more tangible. As a result, we would go as far as venturing to say that this is one of the best loyalty programs in the UK.

21 Casino Level Up

Conclusion: A Wealth of Enjoyment


21 Casino is renowned for having the crème de la crème of software providers all under one roof. Pragmatic Play, Play’n GO, Red Tiger Gaming, Microgaming (Games Global), and IGT are just a handful of the names that feature.

On top of this, the casino combines some of the most sought after progressive slots with big-name titles including Mega Moolah and WowPot on offer. Admittedly, it is missing Playtech and its Age of the Gods jackpot collection, but still, the current selection is impressive.

Live casino players also get a good run of it with Evolution Gaming and Pragmatic Play Live just enough to add a decent number of tables and game shows to the casino’s quality iGaming library.

However, the virtual tables section (if you don’t mind RNGs) more than makes up for this with a decent variety of roulette, poker, and blackjack titles. A mobile app wouldn’t hurt either, but web browser gaming is just as easy to access.

Overall, with 21 Casino’s variety of thrilling high-quality games, unparalleled rewards through its loyalty program and bonuses, and exceptional customer support, 21 Casino stands out as the prime choice if you are an avid online casino enthusiast.
