21 Casino - Online Casino Review


21 Casino is a suave-looking, popular online casino site that offers an impressive welcome bonus of 121% up to £300 for new players.

With a strong selection of games, especially when it comes to slots, there’s something to suit even the most particular tastes here, with big names and cult developers all providing input to ensure a diverse and varied portfolio.

Read on for a full rundown of 21 Casino’s games, bonuses, banking options, and more.

Pros and Cons

  • Huge range of slots
  • Decent welcome bonus
  • Live chat support
  • Limited live casino options


There are over 1,000 titles available at 21 Casino. The focus here is clearly on slots, and there’s a good number of software developers providing these. From big names like Microgaming and NetEnt to smaller studios growing in popularity like ELK Studios and NoLimit City, there’s plenty of variety here.

There are some other game types, Evolution provides several live dealer options, for example, but compared to the slots, the list is much shorter.


The casino’s games collection is quite large and diverse, so players of all tastes and experience levels should have no problems finding games to suit their needs. There are around 500 of them altogether; as well as video and classic slots, progressive jackpots, table games and live casino games, there’s a selection of other games, including bingo, a few virtual sports games, over a dozen video poker titles and two scratch cards.

Whittling down the games collection is easy enough since the games are grouped into various categories, each with a number of sub-categories. You also have the option to sort the games by most popular, most recent, A-Z and provider. Clicking on the RTP button shows reveals what the RTP is for each of the casino’s games – a nice touch that should help players find which games are more likely to pay them back more of their money.


The 21 Casino slot selection is the centrepiece of the site’s games selection, with progressives and other jackpot slots standing out with over 100 options.

Pretty much the full portfolio of NetEnt and Microgaming slots can be found here, but it’s the diversity that sets this selection apart from the competition.

A huge list of software developers is present here, ensuring something to suit all tastes.

Searching slots is easy here, with various tabs separating slots, and the ability to search by theme as well as title and developer.

From classics like Irish Eyes and Mega Moolah to the latest releases from all the featured software providers, 21 Casino is a must for any true slots fan.

Live Casino

The live dealer options at 21 Casino are predominantly provided by Evolution Gaming, generally accepted to be the absolute best when it comes to live casino options. Additionally, a few titles from Pragmatic Play, another talented developer of live-streamed casino games, are also available.

The downside, however, is that the number of games offered here is quite small. While we are all for quality over quantity, there is certainly space for more here.

The highlights of the selection include Evolution’s Lightning Roulette and Ultimate Texas Hold’em. The best options aren’t traditional casino games, however, but gameshow style titles including Crazy Time, Dream Catcher, and Monopoly Live.

All games are streamed live from Evolution and Pragmatic’s respective studios, with trained and friendly croupiers, seamless streaming, and great quality graphics.

The 21 Casino Live section is a good distraction for those looking for a change between slot spins, but as it stands there are more extensive live casino catalogues out there.

Table Games


Including the live casino options, the total blackjack titles at 21 Casino number just over 20, which is quite low compared to other sites.

As with the live casino options, there are some excellent games here, including Felt’s Perfect Pairs Blackjack, Relax Gaming’s Blackjack Neo, and Microgaming’s Atlantic City Blackjack Gold Series.


In terms of roulette options, the selection here is also relatively small, with a little more than 20 games between the RNG and live casino titles.

Double Ball Roulette from Felt is a high octane offering, and Lucky Strip from High 5 Games is an interesting take on the concept. Meanwhile, NetEnt arguably offers the best classic European Roulette option here.

But beyond these highlights, the list runs out far too quickly, and we hope to see more roulette options added here soon.


21 Casino has around 20 poker games, and, when compared to other non-poker-focused online casinos, this is actually quite a competitive number.

Again, the live dealer options lead the way here, but RNG standouts include the traditional Casino Hold’em from NetEnt, the intriguing All Aces Poker from Microgaming, and Shuffle Master’s take on the popular Pai Gow Poker.

There are a few different deposit and withdrawal methods available at 21 Casino. There are certainly online casinos that offer more banking options, but there’s a method to suit most players here.

Debit card payments are the most popular, with Maestro, Mastercard, and Visa all accepted. You can also deposit via e-wallets including Neteller and Skrill, through Trustly, via your phone bill with Boku, or using the prepaid Paysafecard.

In terms of withdrawals, options are more limited, with Boku, Paysafecard, and Trustly all operating as deposit-only methods at 21 Casino.

Withdrawals can be processed in as little as 12 hours once a request is put in at the cashier, but they can take as long as 36 hours for some methods. Once released by the casino, the amount of time it takes for your money to get to you depends on the chosen withdrawal method.

Welcome Bonus

  • Once you’ve signed up, you’ll be credited with 21 free spins even before you’ve made your first deposit; these free spins can be used on the Starburst and Starburst Touch games.
  • When you come to make your first deposit of at least £10, you’ll be credited with a 121% unlimited match bonus and 10 bonus that can be used on most of the casino’s NetEnt games

Wagering Requirements

The 21 Casino welcome bonus comes with a 35x wagering requirement, which is about average for online casino sites.

Bonus funds alone are subject to this requirement, which is preferable compared to some sites that attach the requirement to the total sum of the bonus and the deposit.

However, the problem here is that the small print states only winnings from the bonus will count towards the wagering requirements. That means you have to win 35x the bonus, which in itself is a tall order. If you claimed the full £300, for example, you would need to wager the full £300, win £10,200 with those funds and then wager the lot on-site. After that, any winnings you accrue from the £10,500 wagered funds would be available to withdraw.

Along with needing to achieve this in 30 days, you can only make a maximum bet of £5 per wager with your bonus funds.

Games also contribute differently to the requirement, so be sure to check on the 21 Casino site so you know which games contribute 100% of your wagers to the wagering requirements.

Additionally, if you withdraw any of your deposit before you’ve reached the wagering requirement, the bonus funds are immediately invalidated.

As far as welcome bonus terms and conditions go, these are very severe and make unlocking bonus-related withdrawals all but impossible. While the bonus funds are nevertheless a means to get acquainted with the site and its games, it’s important to note that you won’t glean much value from them beyond this.

High Rollers

There doesn’t appear to be any sort of VIP club or loyalty scheme at the casino, so those used to experiencing the VIP treatment may want to consider playing elsewhere. For some of the table games, there are versions aimed at high rollers that have higher betting limits.

Device Compatibility

Desktop, Tablet and Mobile Experience

If you want to access 21 Casino and play its many games while on the go, you can do so through your mobile device’s web browser. The mobile casino is fully optimised for mobile devices and is compatible with both Android and iOS devices. Its layout is designed to better suit mobile devices such as smartphones and tablets, and it’s slightly less cluttered than the desktop site. In terms of what it offers, it comes with all of the desktop casino’s promotional offers, as well as a large selection of its most popular games. Overall, the mobile is well worth checking out it if you’re keen to gamble while out and about.

App Review

There is no 21 Casino bespoke casino app for any mobile device at the time of writing.

21 Casino review summary

All things considered, 21 Casino is a very solid online casino offering, especially if you’re a fan of slots.

The video slots selection available at this online casino site is very impressive, with well over 1,000 to choose from, and an impressive list of developers behind them.

The wheels fall off a little when it comes to other game types, especially with the live casino. However, there is a smattering of other game categories, so slots fans looking for a change of scenery can find plenty here.

The welcome bonus is good, even if it is let down a little by the wagering requirements and associated T&Cs, and the loyalty bonus is nice and simple.

Design-wise, there’s nothing new here, but that isn’t the point. This is a classic look, and it works very nicely.
