21 Casino Pros & Cons

  • Unique welcome offer
  • Feature buy games available
  • No FAQs section

The welcome offer at this online casino is unique in that you get a bonus as well as a free spins no deposit bonus. This is the first time we’ve seen an online casino really theme their welcome offer rather than giving a generic bonus, so it’s definitely unique.

The offer is 

  • 121% match bonus up to €300 plus 21 free spins

Key T&Cs to be aware of:

  • Wagering requirements of 35x apply
  • Available to new Irish players, 18+
  • Not available to players in the UK
  • Deposit at least €10 to claim
  • Deposits made via Skrill or Neteller are not eligible
  • Please gamble responsibly

21 Casino Bonus Codes  

At the moment, none of the promotions at this online casino require the use of a bonus code. They will either automatically credit to your account, or you might need to opt in at the cashier stage when making your qualifying deposit.

If they do introduce bonus codes in the future, we’d expect that they will be applied within the cashier and would then trigger the appropriate bonus. 

21 Casino Free/Extra Spins 

At the time of writing, there are currently no bonus spins offers available, with the exception of the welcome package. However, promotions do change and players may be eligible for different offers, so we have no doubt that bonus spins are available upon occasion. When they are, they’ll be subject to 35x wagering requirements unless otherwise specified, and the maximum win is €100.  

21 Casino No Deposit Bonus 

The no deposit casino bonus Ireland here is definitely one of the better offers out there. You’ll get 21 free spins on the hugely popular Book of Dead slot, just for signing up! You don’t have to do anything, these are simply credited straight to your account. These spins come with 35x wagering requirements and must be used within 10 days.  

Other 21 Casino Bonuses 

Promotions at this online casino are variable, so to keep up to date you should ensure that you’re signed up to receive marketing emails. You can also enable alerts on the promotions page on the site. 
In addition to bonus spins and match bonuses, 21 Casino runs the occasional competition, which may take the form of a tournament or a prize draw. Prizes may include bonuses and free spins. 

21 Casino is home to an amazing array of games, spanning from the latest slots, to classic card games. With new releases happening all the time, jackpots offering massive payouts, and even a great range of live dealer games, there sure is something for everyone.

Outside of the live dealer environment, there’s a good range of table games, mainly blackjack, roulette and poker . There are a few unique variations of these, like Texas Hedge’Em and Space Invaders Roulette.

For something fun and unique, try out slingo, which is a combination of slots and bingo, or opt for one of the quick and simple scratch games. 

21 Casino Live Casino 

The live casino games here are powered by Evolution Gaming. If you’re at all familiar with online casinos, you’ll know that Evolution are industry leaders when it comes to live gaming. From the professional dealers, to the standard of the streaming, everything here is top-notch.

Top live casino games include the likes of blackjack, baccarat and roulette, but there are also a number of exciting gameshows like Gonzo’s Treasure Hunt and Dream Catcher.

Live dealer games are available on both desktop and mobile, and function just as well on either. 

21 Online Casino User Experience

21 Casino has definitely aimed to create a luxurious look and feel, and they have certainly achieved this. The website is also pretty easy to use, with good filtering options on the games page, allowing you to view games by provider, or by category like jackpots or new titles. In addition, you can browse by feature like sticky wilds or megaways.

A brilliant feature which we haven’t seen at any other online casino is that on the games page you can hover over each game and you’ll be able to see the level of volatility, the reels, number of win lines, and the provider. You can also favourite games here for easy access in the future.

Once you’re logged in, you’ll see your balance displayed at the top of the page, along with any special bonuses. You can enter the cashier with just one click.

In terms of ease of use, the only drawback is that the menu is represented by icons rather than words, so although it creates a premium look and feel, it can be a bit difficult to navigate at first. 

21 Mobile Casino

When you first log in to the website on mobile, you’ll be directed to download an app. This is not the traditional kind of app you might expect however - it’s a more modern solution which simply involves adding the website to the home screen on your phone.

No additional software is needed, as the games are all built for use on both desktop and mobile. The minimalistic navigation translates really well onto the mobile casino as well, so you won’t lose any quality of play, even on a smaller screen. You can play on both mobile or tablet, no matter whether you use iOS or Android. 

Deposit and Withdrawal Methods Available at 21 Casino 

21 Casino offers an impressive number of payment methods for Irish players, so you’re certain to find the one you prefer. The minimum deposit amount for all methods is €10 and the ways to pay include: 

  • Bank cards
  • PayPal
  • Open banking
  • NeoSurf
  • Instant bank payment
  • CashToCode
  • Skrill
  • Neteller
  • paysafecard
  • Bank transfer

You can withdraw to the majority of the same methods - with a notable exception being paysafecard - but you’ll need to withdraw to the same method that you used to make the deposit. The minimum withdrawal amount for all methods is €10.

Withdrawals will remain the processing phase for 1 - 2 working days for all payment methods, which is in line with what you’d see at most other online casinos.

21 Casino Slots 

There’s an outstanding selection of slot games to look forward to, from some of the biggest names in the business, like Microgaming and NetEnt.

New titles are added regularly, with just a few of the top new releases at the time of writing being Genie Nights, Donkey Dash and Blazing Clusters. Perennial favourites include Starburst, Book of Dead and Big Bass Bonanza.

We’re happy to see that feature buy games are becoming more popular, as these allow you to buy your way into the exciting bonus rounds. Some options to try out include Gates of Olympus, and Madame Destiny Megaways. And speaking of megaways, these are hugely popular at this Irish online casino - they’re really exciting as your ways to win are always changing.

You can also play games with features like cluster pays and sticky wilds, and of course there’s a good variety of high volatility options if that’s your preference.  

21 Casino Payout Rates 

The RTP is the return to player percentage, which refers to the amount of money staked on a game that should return to players over time.

21 Casino doesn't have one central location where you can view the RTP for all games, but it’s available in the game info once you’ve entered a game. As a general rule, table games like blackjack have the highest RTP, and this can sometimes be more than 99.0%. Slots tend to have an RTP of 95% to 98%, with jackpots being at the lower end of the scale.  

Progressive Jackpots 

What’s so exciting about progressive jackpots, is that they get bigger every time someone spins, so the potential payout is always on the rise. 21 Casino offers quite a few smaller jackpots which pay out relatively often, and where the potential winnings can reach five figures.

However, if you’re looking for something a bit bigger, you’ll be thrilled to find out that a few of the Mega Moolah progressive jackpot slots are available here, including the classic version as well as the Juicy Joker game. It’s not unusual for the payout amounts for Mega Moolah to reach a whopping seven figures.  

Software Providers 

This Ireland online casino works with well over 100 different software providers - a truly impressive variety. There’s a feature on the games page which allows you to filter by provider, which is handy to help you find preferred games.

The big benefit here is that you’ll find games from the world’s biggest providers, like NetEnt, Microgaming and Play’n Go, but you’ll also have the opportunity to explore a whole selection from smaller studios. Push Gaming, Spin Play Games, and Swintt are some slightly smaller providers that are well worth checking out.

There are lots of perks to becoming a VIP, for example enhanced and tailored bonuses, and of course the services of a dedicated VIP account manager.
