21 Casino

online casino review


21 Casino is owned by White Hat Gaming, one of the most successful white label brands in the Irish online casino space. This means it shares a backend platform with a whole host of other sites, but that hasn’t stopped 21 Casino imposing its own personality. The site is one of the slickest we’ve seen, thanks to its black and gold theme and easy navigation.

There’s plenty more to explore yet though — in this impartial review we’ll run you through all the games, bonuses, payment methods and customer support options on offer at this site.

What we like

  • Demos available – Irish players can play demo versions of games without an account.
  • Site design – a slick website layout with excellent navigational options.
  • Wide variety of games – nothing is off the table at 21 Casino
  • Many software providers – lots of variation thanks to the inclusion of over 100 developers.

What we don't like

  • Welcome offer T&Cs – 35x wagering requirement can only be fulfilled with bonus funds. Winnings from no deposit spins are also not instantly withdrawable.
  • Very few promotions – currently no bonuses available for existing customers, while the VIP programme is invite-only.

21 Casino refers to its welcome offer as world class, but that’s for us to decide! The main event is a matched deposit bonus available for all new customers. Before that, however, you can bag 21 no deposit bonus spins for the legendary slot game ‘Book of Dead’ as soon as you sign up.

If you do fancy adding funds to your account, you’ll then be able to claim the matched deposit bonus. For branding purposes, it’s a 121% deposit match up for grabs — we aren’t complaining, as it’s bigger than the usual 100%. This means if you deposit €100, you’ll get an additional €121 in bonus funds. The maximum bonus you can gain is €300, which is rather high compared to the competition.

The main drawback with this otherwise solid welcome offer is that the 35x wagering requirement — already high as it is — can only be satisfied using bonus funds. This’ll make it really tricky to wager enough to turn the bonus into withdrawable cash. Additionally, wins from the bonus spins are credited as bonus funds, so you can’t immediately withdraw these either. Since this isn’t the most player-friendly deal, it’s best to see the welcome offer simply as an opportunity to try out the games on the site.

As for the other promotions available at 21 Casino, the collection is rather sparse. At the time of writing, the focus is very much on the VIP deal. There are four levels to it — Silver, Gold, Platinum, and Diamond. The programme is invite-only, so you’ll have to wait for a message from the site to be able to get involved. With such an exclusive programme, we’d like to see some other offers for existing players, but currently there’s just the one — ‘Recommended Game’, which actually isn’t an offer at all, just a link to a popular slot game on the site.


21 Casino’s wide range of software providers is one of its clear advantages over the competition. There are over 100 developers included on the site, ensuring there’s lots of variety within the games catalogue. You’ll find big names in the slots industry such as NetEnt and Microgaming, along with live casino specialists Evolution. These are supported by a huge mix of smaller developers, including Four Leaf Gaming, Jade Rabbit Studios, and Pear Fiction Gaming.


On some sites, the live dealer category is much larger than the RNG table games section, but that isn’t the case here. There are loads of options available if you fancy joining a table in a solo game. You’ll notice a greater range of developers featured here too — with slots specialists such as Microgaming and Relax Gaming also providing casino games such as All Aces Poker and Roulette Nouveau. Furthermore, the inclusion of games such as 10p roulette ensures that 21 Casino caters to all budgets. And don’t forget, most of these games are available to play completely free in demo mode.

Live Casino


With so many software providers featured on the site, it’s no surprise that there’s a huge range of slot games available to play at 21 Casino. With over 1,500 in total, you’ll find everything from standard 5-reel games, to progressive jackpots, to games with modern mechanics like Cluster Pays and Megaways.
21 Casino’s excellent navigational features mean you can filter by the specifics of games, such as those that include 3×3 Mega Symbols, like Gigantoonz and Raiders of Fortune, and those with sticky wilds, like Danger High Voltage and The Dog House Megaways.

Live Casino

While 21 Casino’s live dealer section isn’t as varied when it comes to software providers, we’d argue it strikes the right balance. Some sites exclusively offer Evolution titles — the industry leader in this category — and indeed you’ll find its games make up the bulk of the collection here. However, there’s just enough range thanks to the inclusion of some Pragmatic Play and Ezugi titles, ensuring players have a choice over game variations and aesthetics. That said, the blackjack selection is on the low side, as there are only three live versions of this game featured here.

If you fancy something a bit different to the usual table games, Evolution and Pragmatic Play both offer some live game shows, such as Dream Catcher and Crazy Time.

21 Casino offers a decent spread of payment methods, so players have plenty of options when it comes to funding their account. In addition to Visa and Mastercard, there are plenty of alternatives including prepaid cards like Paysafecard and Neosurf, as well as e-wallets like Neteller and MuchBetter. Skrill and PayPal don’t appear to be supported, which will come as a disappointment to some. Trustly is another great option if you’d rather not share your card details with the casino.

21 Casino’s withdrawal processing time is listed as 1–2 days. One day is about the average, but anything more than that would be considered slow. The time after that is purely down to the withdrawal method you choose.

Method Min deposit Minimum Withdrawal Limit Withdrawal Processing Time
Visa Mastercard €10 €10 3–5 days
MuchBetter €10 €10 1–3 days
Neteller €10 €10 1–3 days
Paysafecard €10 N/A N/A
Neosurf €10 N/A N/A
Bank Transfer €10 €10 3–5 days

Design & Usabillity

The usability of 21 Casino is another of its key strengths. It’s rare to have so many niche filtering options within each category. For example, you can filter slots by Meagways, Buy Feature, Cluster Pays, Mega Symbol (3×3) and Sticky Wilds. This makes it easy for players with particular tastes to find new games they like. What’s more, we’re always pleased to see an option to search by software provider — at 21 Casino you can not only do that, but also view a full list of the providers with links to their individual pages.

The site itself has a very premium quality, with the slick black and gold theme matching up with the seamless navigation.

Support Options

Customers can get in touch with 21 Casino either via email or through the live chat service. The live chat supports six different languages, which is a real plus. The casino is also active on Facebook, so you can drop them a message there if that’s preferable to email or live chat.

App Review

21 Casino is yet to offer a mobile app for Android or iOS users. This isn’t uncommon for new casinos, but as the site has been around for four years now, we’d hope to see one developed soon.

There is, however, an app available through the website that you can install onto your desktop or laptop. This’ll give you faster loading times and save you having to search for the site through your browser each time you want to play.

The vast majority of the games library is available on mobile with just a few absences here and there — 42 of the 49 live dealer games are available through the mobile site.

21 Casino is an excellent option for players who are all about the games themselves. There’s an enormous collection of titles on offer, including over 1,500 slot games. Couple that with over 100 developers and there’s tons of variety here in each of the categories. The fact that Irish players can play demo versions of the games before they’ve even signed up is also a huge plus, giving you the chance to try out the site and its games before committing your cash.

Bonus hunters will be less pleased with 21 Casino, though. Although the welcome offer and no deposit spins are appealing on the surface, the terms and conditions attached to them mean that it’ll be very challenging to actually withdraw any cash. Additionally, at the time of writing, the only promotion for existing players is the VIP program, which itself is very exclusive and by invite only.

Still, if you’re in it for the games and are looking for an impeccably designed casino with excellent navigational options, 21 Casino is definitely worth a look.
