21 Casino review


21 Casino is a fun and modern casino that many players may not be aware of but should join regardless. Full of a staggering number of games with a strong focus on slots and poker, it presents itself as a well-formatted, simple to navigate website which players can easily gain access to and interact with. Its colour scheme may be a little drab but that adds to the appeal in its own, odd way and, seeing as this website was launched all the way back in 2000 (yes, nearly twenty years ago!) it most certainly knows what it’s doing.

It’s surprising then, considering how long it had been around, that it isn’t as popular as, say, Casumo or Mr Green. It does, after all, have all the right ingredients to make for a timeless, excellent mobile casino. Why is 21 Casino not more popular? Well, we’d argue that it’s as popular as it needs to be, nothing more. The trouble with super-mega mainstream casinos tend to lose their appeal and their fame pretty quickly while a cult classic, so to speak, can endure. But could 21 Casino do more to appeal? Would it hurt o have a little bit of a makeover? All this and more we will try to answer in our full review.


Welcome Bonus

The first thing you’ll notice about 21 Casino is it’s rather… unusual welcome bonus. With 121% on your first deposit with no limit required plus ten extra spins. So, if you deposit £10, you get £12.10 as a cash match bonus and you’ll have £22.10 to play with. The ten spins that come with this aren’t the only instance of extra spins, either. Sign up to the casino today and you’ll get 11 free spins extra, making that a total of 21 extra spins to use on NetEnt’s Starburst and Starburst Touch. An unusual bonus amount indeed but seeing as it keeps to the whole ’21’ theme, doubtless inspired by Blackjack, then we think that it works.

The wagering requirements for the welcome bonus is 35x. Surprising, considering we half-expected it to be 21x, just to carry on the whole 21 theme. But 35x is good enough requirement for players to stick to. It’s actually below average, considering that 40x is about the average. In any case, this promotion is for new members only and works only once. Sorry if you’re already a member! This is one is just for the newbies. Please also bear in mind that the deposit extra spins will only work on some select slots. More information on that can be found on 21 Casino’s promotions page.

The sheer amount of games that are available at 21 Casino is staggering. There is a massive selection of the best online casino games the internet has to offer including all the casino classics like blackjack, roulette and baccarat plus some Caribbean stud poker, punto banco, pontoon and Texas Hold ‘Em. Each gave has variations, so players are guaranteed to find the version that suits them best. Not bad. Not bad at all. In addition to these table games, which can be played digitally or live by the way, players can indulge themselves in video slots and progressive jackpots from across the industry. All can be played on mobile while out and about or on desktop from the comfort of your own home.

The variety of games on display are down to the fact that 21 Casino have enlisted the software from many different providers. Among the ranks, you have top developers as well as small time developers like: NetEnt, Quickspin, ELK Studios, Leander, Multicommerce, NYX, Thunderkick and Amaya. That’s not even all of the developers that you can find! The amount of games guarantees that there will be no boredom at 21 Casino and that is promise. Sign up today and you could be playing games such as: Foxin’ Wins, Gonzo’s Quest, Starburst, Guns ‘N Roses, Big Bad Wolf, Space Wars, Dracula, Jimi Hendrix, Cherry Blossoms, Monster Wins, South Park, Jack and the Beanstalk, and many, many more besides.

Of course, slots and table top games aren’t the only thing that you can find at 21 Casino. Sniff around and you may find one or two scratch card games which we know you’ll love. Virtual Soccer and Virtual World Cup are particular favourites of ours and represents the more sport-betting flavour to this online operator. It makes for a lot of variety and it makes you question why you would want to go anywhere else.



We’ve touched on the software that 21 Casino uses to provide its many games. Now let’s look at how the website operates itself. First thing to note is that it operates splendidly on mobile as well as desktop, meaning it has a strong foundation to go for in the mobile gambling industry as many more players are likely to take to a casino that can accommodate both.

While the site does not have its own app, we believe this amounts to very little anyway seeing as the site works just as well when you access it through your device’s web browser. There’s not much else to add here. Nothing out-of-the-ordinary or sophisticated enough to make the site too complex to operate on multiple devices and that’s what works about it. After all, a mobile casino wouldn’t be of much use if it could not be accessed via mobile. Or, if it could be accessed, it would be unnavigable seeing as a desktop version of a website doesn’t make for a good mobile version of that website.

You can even access the mobile version of the 21 Casino site by clicking at the link at the far bottom of the desktop homepage. Handy but not exactly necessary. Still, it’s nice to compare the two of the same screen, we suppose. It makes for an interesting contrast to see two versions of the same website intended for different devices side-by-side. Makes you appreciate one more than the other and marvel at how it’s done. 21 Casino is run by Hat Gaming Ltd and has license to operate in the UK based from Gibraltar.
