21 Casino is a well-licensed online casino brand that’s soon to celebrate a decade in the EU iGaming market. That’s impressive longevity when you consider how competitive the industry is these days, and a good first sign. Within our complete 21 Casino review, we’ll also explore their bonuses (spoiler alert: there is a no deposit free spin offer!), game selection, sign-up process, licenses and much more. Read on to discover if 21 Casino is worth putting on your radar as well!

21 Casino Bonuses and Promotions

Bonus offers at 21 Casino seem to be few and far between, unfortunately. There is a decent welcome package covering two types of casino bonuses, but seemingly nothing to tempt existing bettors to reload their accounts.

Welcome Bonus

The Welcome to 21 bonus is two-pronged. You’ll be credited with 21 free spins for use on the popular Book of Dead slot. There’s also a 121% deposit match bonus, up to a maximum of 300€.

It’s nice that there are two facets to this welcome package, with a chance to trial one of the most iconic slot titles in recent years, before receiving bonus funds linked to the size of your first deposit. A no deposit free spins bonus is always a big plus for us.

It’s just a shame that there’s not further incentives for your second or third deposits. Or indeed incentives to reload your account whatsoever.

Bonus Terms & Conditions

The free spins for Book of Dead will be credited as soon as you open your 21 Casino account. To activate your deposit match bonus, you’ll need to deposit a minimum of 10€. Any deposits using Skrill or Neteller are ineligible for this promotion.

There is a cap on your potential winnings from your Book of Dead free spins. This is set at a meagre 100€, which we feel is a bit low. Yes, it’s a no deposit bonus, but we would like to see a bit of a higher cap here.

The bonus funds from the deposit match offer come with 35x wagering requirements attached. You must roll over your bonus funds 35x within 30 days of receiving it or risk forfeiting the funds in full.

VIP Program

The 21 Suite is the only other promotional feature within 21 Casino. This invite-only VIP program has four tiers of benefits, ranging from Silver and Gold to Platinum and Diamond. The latter being the most extravagant of all, including personalised weekly bonuses, birthday gifts and much more.

21 Casino Payment Methods

As a new customer of 21 Casino, you’ll have multiple options to deposit into your account. These range from conventional debit cards (Visa and Mastercard) through to e-wallets like PayPal and Jeton Wallet. You’ll also have the option to use Revolut cards, MiFinity and Neosurf too.

None of the above payment methods are seemingly available for withdrawals though. When we tried to process a withdrawal, we were directed to initiate a bank wire transfer, with no alternative. Although this is one of the most secure withdrawal options, it’s also one of the slowest.

21 Casino Registration

The sign-up process for creating a 21 Casino account is very simple. Create a username that’s available, as well as a secure password to get started. You’ll then need provide your address and phone number. Make sure your address is the one you use for utility bills and bank statements as they’ll need to match to pass Know Your Customer (KYC) checks.

Once your account is created, the site will email you to confirm that it’s good to go. You’ll have the opportunity to reset your password at this stage too.

  • Step 1: Complete the ‘Get Started’ section of the registration form.
  • Step 2: Enter your name and date of birth.
  • Step 3: Provide your address, postal code and city/town.
  • Step 4: Supply a phone number for use to secure your 21 Casino account.
  • Step 5: Visit your casino wallet and choose one of the available deposit methods.

21 Casino KYC and Security

Since 21 Casino is regulated and licensed by the MGA, the operator must comply with the Know Your Customer (KYC) framework. Verification of your identity and address is compulsory before you can initiate any withdrawals from your 21 Casino account.

You’ll need to upload photo copies of the following:

  • Proof of ID
    Usually a government-issued ID card, driving licence or passport.
  • Proof of address
    Typically a utility bill or bank statement dated within the last three months.

From a player security view, 21 Casino is up there with the best in the business. The site is fortified with state-of-the-art SSL encryption technology, awarded with a Rapid SSL certificate that encrypts sensitive data between you and the casino.

Games to Play at 21 Casino

There are some areas of 21 Casino where game selection is somewhat lacking. However, there’s no doubt that if you love slot games you’ll get on just fine here. It’s the choice of table games and live dealer games which leaves a lot to be desired, resulting in a rather two-dimensional online casino experience.

Slots

The 21 Casino slot section is well-organized. You can scroll through their entire slot library, or you can check out their categories based on Megaways slots, Cluster Pays slots, slots with sticky wilds and those slots which allow you to buy directly into their bonus features.

It’s clear that slots is where 21 Casino really excels. Their game library consists of 2,000+ slot titles, giving you access to all kinds of slot themes, including officially licensed games inspired by pop culture, ranging from The Terminator to Ted.

21 Casino has a ‘Top Games’ category which showcases all of the most popular slot games within the site. You’ll find household names like Rise of Olympus 100, Sugar Rush and Gigantoonz listed for play right here.

Table Games

If you’re someone who still enjoys RNG-powered virtual table games like blackjack, roulette and baccarat, there’s 25 of these tables waiting to be explored. There’s also some old-school card games from Shuffle Master, such as Mississippi Stud and Casino War, which are games most commonly found on the floor of brick-and-mortar casinos.

Nevertheless, a choice of 25 table games again feels somewhat light, with Scarabet offering almost three times as many RNG-based virtual casino options.

Live Casino

21 Casino’s live dealer casino library is where the site lets itself down, in our opinion. It’s largely powered by Swedish powerhouses Evolution and Pragmatic Play, but there are only 37 live dealer games to choose from. When you consider that Evolution powers most of the live casino, it’s fair to say that it’s quality over quantity, but it’s still a drop in the ocean compared to the 900-1,000 live casino games on offer at Ritzo Casino.

21 Casino Software Providers

21 Casino has been live since 2015, which means it’s had almost a decade to cultivate links with the best online casino game studios in the industry. That’s why we’re not surprised it is currently supplied by 130+ software providers, spanning online slots, table games and live dealer casino experiences.

  • pragmatic logo Pragmatic Play

  • microgaming logo Microgaming

  • rabcat logo Rabcat
  • blueprint logo Blueprint Gaming
  • lightning box logo Lightning Box Games
  • inspired gaming logo Inspired Gaming
  • kalamba Kalamba

This equates to a four-fold increase in game providers at Winnerz and it even manages to beat Stupid Casino’s 110-strong supplier list, which stands proudly as one of the biggest online casino game libraries in the EU market.

21 Casino Mobile Experience

The 21 Casino platform is HTML5-powered, which means it’s fully responsive for play on any device, no matter the screen size. There’s also the option to install the 21 Casino web app within your browser. As with most EU-focused online casinos, there’s no native iOS or Android app, which is no big deal when you get exactly the same user interface via your preferred mobile browser.

21 Casino License and Ownership

When it comes to building trust and confidence in an online casino, nothing does it better than great licensing and regulatory oversight. We’re pleased to say that 21 Casino is regulated by the Malta Gaming Authority (MGA), which remains the number-one EU iGaming jurisdiction.

  • mga logo MGA

Its commitment to complying with MGA’s regulatory framework demonstrates how serious this platform is for European online casino enthusiasts.

One thing to note is the site’s ‘brand manager’, White Hat Gaming Limited. As with so many EU-focused online casinos, 21 Casino appears to be led by a white-label company, sharing the MGA license with multiple other brands. There’s no formal confirmation anywhere of the site’s underlying owner.

21 Casino Customer Service

There are three ways to contact 21 Casino’s customer support department. You can email via support@21casino.com, use their 24/7 live chat or visit the Help Centre with a host of FAQs capable of answering basic queries without having to trouble a customer support agent.

When we spoke with a live chat agent, they responded within a couple of minutes and were very courteous. They went out of their way to explain the bonus terms and conditions as a new customer.

21 Casino Experience from Other Players

21 Casino has been operating since 2015, so we thought it was worth checking out the feedback on the brand. We headed over to their official Trustpilot page which makes for interesting reading. The site averages 1.5 out of 5, with 81% of users rating it 1 out of 5.

Nevertheless, there’s only 113 reviews in total here, so it’s hardly representative of the tens of thousands of players that have used the 21 Casino platform. Yet, it is worth taking into consideration.

21 Casino Summary and Rating

There’s a lot to like about 21 Casino. It’s stood the test of time in the industry and continues to offer a good selection of new and popular slot games. The meagre choice of table games and live casino tables is what really lets this site down. There’s also a lack of promotions and gamification such as slot tournaments which would keep players engaged on-site for longer.

Nevertheless, we still think the welcome bonus and slot section is worthy of a respectable rating of 4.3/5, with a higher rating not beyond reach if it starts to offer more incentives to existing bettors.

My name is Markus and I’m the head writer for both the English and Swedish version of Slotsoo. Online slots has been a dear hobby of mine for many years so I’m happy to have found a job in this field. I like to hunt for new MGA casino since they tend to give the best value for my money without safety risks or tax complications thanks to EU.
