21 Casino Review

See our old review below:

Founded just under three years ago, 21 Casino claim to offer a ‘new generation online casino with a smooth and luxury feel’, and in this review, we’ll find out if they live up to their word.

First things first, here’s a brief history of this increasingly popular site. 21 Casino was originally founded by a group of Dutch casino enthusiasts that felt compelled to bring something a bit more lavish and bespoke to the world of online casinos, and thus the site was born.

21 Casino now works closely with some of the most influential game providers, including big names such as NetEnt casinos, Amaya, NYX and Quickspin.

As mentioned previously, this particular online casino has looked to provide a smooth and luxury filled experience, and this is evident from their sites aesthetics. They have opted for a smart-looking black and white colour scheme, with gold highlights that grab your attention throughout.

The company logo has a regal feel to it, with the words 21 Casino sitting proudly beneath a crown at the top of the page. Everything about the site oozes style.

There is nothing too gimmicky and it has a very minimalistic style, which makes for great user experience and instantly fills you with confidence. The layout follows this trend, with clearly displayed page headers down the left-hand side, and an ever-revolving banner that fills the top third of the screen.

Signing up and logging in is a breeze, simply select the ‘Sign Up Today’ option in the top right-hand corner, follow the simple instructions and you’ll be all set within minutes.

21 Casino Promo Code

When browsing the site, you may notice that the 21 Casino promo code and bonuses all seem to have one thing in common….the number 21. For example, the welcome offer currently available to new customers is a 121% bonus.

You should be aware, the welcome offer for this site often changes. At the time of signing up the offer, you get may differ slightly to the ones mentioned on this page. Another welcome offer they like to dish out is the 121% bonus on your first deposit. This offer is for an unlimited amount, however, there are certain terms, conditions and wagering requirements that apply.

More Promotions and Deals

In addition to these welcome offers for new customers, 21 Casino also has a whole host of ongoing promotions to keep their existing customers coming back to the site. For instance, existing customers can currently take advantage of the ‘Hangover Bonus’.

This particular offer sees customers receive a….you guessed it….21% bonus on their first deposit on a Monday and Tuesday, up to £210. Again, no promotion codes or bonus codes are required to trigger this promotion.

Finally, 21 Casino is home to the ‘Loyal Royalty’ program. This loyalty scheme sees its users rack up points for every stake, these points can then be redeemed for bonus cash to play across the site. All in all, this site gets a big thumbs up from us for its welcome offer and promotions as there is something for every type of player, no matter what their budget.

Games & Features

It’s no good having a top of the range website and great offers and promotions if your site doesn’t have the content to back it up. Thankfully, 21 Casino most definitely does.

This website is currently home to an obscene slots library, with literally hundreds of games to choose from. They haven’t simply opted for quantity over quality either, you’ll find some of the biggest slots game in the business her, including massive titles such as Gonzo’s Quest slot game, Starburst and Hall of Gods, as well as licensed games such as Ted, Guns N Roses and Jurassic World. On top of this, 21 Casino also has one of the biggest selection of table games we’ve ever come across.

More Games & Features

It’s not uncommon for similar sites to offer 10 – 20 table games, but this site is currently home to over 50! Including multiple different varieties of roulette online, blackjack, baccarat and poker. As with any top-rated online casino, 21 Casino give their players the option to play at live tables with live dealers. This is vital for seasoned players, as they like to experience the thrill of being in a real casino, but for the comfort and safety of their own home.

Blown away by the sheer volume of content? Well, take a breath, because it doesn’t end there. If you sign up to this site, you will also be able to play a selection of virtual scratch cards, an authentic bingo game and even virtual betting games, including Virtual Soccer, Virtual World Cup and Virtual Champs League.

We really can’t wax lyrical enough about the games and features on this online casino. Not only have they mastered the quality, but the sheer volume of content available is something else, and definitely more than enough of a reason to sign up and log in today.


We touched on it briefly earlier, but now it’s time to go into a little bit more detail about the software used on this site. As mention previously, 21 Casino currently works hand in hand with some of the biggest software providers in the industry. For example, on this site, you’ll find games from the likes of NetEnt, Thunderkick, Genesis, Leander and many more.

What this does is allow this site to offer a huge games library and ensure they cater for as wide an audience as possible. It also means users can sign up to the site knowing full well that they’ll be able to play the latest, most popular games out there and also have access to fresh and exciting content.

The site has a lovely little feature that allows you to filter the games page by the software provider. We really loved this as it allows users to find their favourite games even faster, and they can also create an experience that is tailored to their needs and preferences. On the whole, we really can’t find fault with this site at all when it comes to their choice of software providers.

Payment Methods and Withdrawals

Now to the not so exciting stuff. As far as payment methods and withdrawals go, this site tends to follow the trend set by others. For example, 21 Casino currently accepts deposits via card and E-Wallets.

  • Maestro
  • Skrill
  • GiroPay
  • Trustly

Withdrawal times often depend on the payment type being used, but you can expect to wait between 1 and 7 working days for withdrawals to be processed fully.
