Design & Overall Gaming Experience

Design & Overall Gaming ExperienceThis gambling operator has opted for a straightforward but elegant design, with a layout that uses mostly black and gold colours. While there is nothing extraordinary or unique about the style of 21Casino, the saying “Simplicity is the ultimate sophistication” certainly rings true here.

The website exudes elegance but perhaps more importantly, it has a clean interface that helps you find your way around quickly and easily. The different sections of 21Casino are simple to navigate and so is the main lobby.

The catalogue is properly categorised, with tables that lead you to the new releases, the most popular titles, the slots, jackpots, live casino, table games, and instant win options. One thing we found particularly useful is that you get to see each game’s RTP and volatility level when you hover your mouse cursor over its thumbnail.

This casino makes things easier for players keen on specific games or software designers. You can filter the portfolio by supplier, which is great considering 21Casino is powered by more than a hundred major and small studios. Registrants looking to play certain releases can type their titles in the search box for quicker access.

Range of Software Suppliers

Range of Software SuppliersWith a staggering 100+ software providers on its roster, 21Casino will impress even the most fastidious casino devotees. However, customers from the UK may not have access to the releases of some software brands due to regulations and licensing restrictions.

The library of 21Casino contains the creations of industry old-timers like NetEnt and Microgaming, both of which have major contributions to the jackpot section with progressives like Mega Moolah, Fruit Fiesta, and Mega Fortune.

Other major studios that have teamed up with the operator include Bally, Barcrest, Felt Games, IGT, Leander, NYX, Play’n GO, Quickspin, Shufflemaster, Scientific Games, WMS, and Thunderkick. Big Time Gaming has supplied some of its most popular Megaways releases.

The casino has further diversified its library through partnerships with various emerging studios that are yet to consolidate their position in the industry. Some less-known software brands you will find here are Storm Gaming, Yoloplay, Seven Deuce, Red7, Pulse 8 Studios, PearFiction Gaming, Northern Lights, and Old Skool Studios.

The bulk of the live-dealer suite is courtesy of the renowned Evolution Gaming although NetEnt also has contributions. You can load the games straight in your smartphone or desktop browser since this is an instant-play casino.

Choice of Games

Betting buffs from the UK who join 21Casino’s community can pick and choose from an expansive gaming library that covers a broad spectrum of player preferences, styles, and bankrolls. You can play against live dealers, hit the reels of hundreds of slots, or try out dozens of table games variations. Instant-win titles are also offered.

Slots Selection

Slots Selection

  • Legacy of Dead
  • Starburst
  • Eye of Horus
  • Immortal Romance
  • Wolf Legend

Reel spinners can hardly complain about lacking diversity as 21Casino delivers a comprehensive slot selection that comprises both classic and modern releases. Those who seek a more orthodox spinning experience can opt for fruit-themed titles like Super Hot Fruits, Reel Rush, and Immortal Fruits.

The slot library gives you suggestions and recommendations, displaying popular tags like Joy, Cherry, Fruit, and Adventure. You can also search for games with distinct special features like respins, multipliers, free spins, scatters, and wilds. There are plenty of those at 21Casino, with some of the most worthwhile releases being Money Train, Book of Dead, Lil Devil, Legacy of Dead, Immortal Romance, and Dead or Alive II.

Thrill-seekers with larger bankrolls get the chance to try various high-volatility slots like Wolf Legend, Deadwood, Punk Rocker, Jungle Spirit, and Tome of Madness. You can check the reel number and the level of variance by hovering your cursor over the slots’ thumbnails. This also displays the theoretical return percentages and the number of win lines in each game.

Blackjack Selection

Blackjack Selection

  • Buster Blackjack
  • Blackjack Pro Monte Carlo
  • 21+3 Blackjack
  • Lucky Ladies
  • Classic Blackjack Gold

The casino is home to a nice blackjack suite containing a dozen or so variations. Fans of 21 who seek the thrill of side wagering have plenty of options provided by Felt Gaming, including Perfect Pairs, 6 in 1 Blackjack, Buster Blackjack, Lucky Ladies, Lucky Lucky, and Suit ‘Em Up Blackjack.

European Blackjack without hole cards for the dealer is also available. Blackjack Pro Monte Carlo is offered in both single-hand and multi-hand format. Microgaming has contributed Atlantic City and Classic Blackjack Gold. Relax Gaming has supplied Blackjack Neo where you can play up to three hands for stakes that range from £1 to £3,000.

Roulette Selection

Roulette Selection

  • Double Ball Roulette
  • Roulette
  • European Roulette Gold
  • American
  • French Roulette

There is a nice assortment of roulette variations at 21Casino, supplied by Microgaming, NetEnt, Relax Gaming, and Felt Gaming. One variant we found particularly appealing was Leander’s Double Ball Roulette. This is a single-zero game where two balls are in play on the same wheel. A fixed jackpot of 1200 to 1 drops whenever the two balls settle on the same chosen number.

NetEnt supplies French Roulette, a variation that supports racetrack wagering, wheel statistics, bar charts, and information about hot and cold numbers. The only quibble is the absence of the La Partage rule. Other variants of the wheel game you can play at 21Casino include American Roulette (NetEnt), European Roulette Gold (Microgaming), and Roulette Nouveau (Relax Gaming).

Baccarat Selection


  • 3D Baccarat

As far as baccarat is concerned, 21Casino offers far less diversity. Players keen on this sophisticated, yet simple card game of chance are facing one variation, namely 3D Baccarat.

This version is developed by the Iron Dog gaming studio. It features enhanced visuals, fast play, and a hand history that shows you the Player/Banker outcomes on previous rounds. The betting range varies from £1 to £500 per hand.

We failed to locate other RNG-based variants but 21Casino compensates with greater versatility in its live-dealer section where you can find numerous tables with different limits to suit any budget.

Video Poker Selection

Video Poker Selection

  • All Aces Poker
  • Jacks or Better Double Up

The casino lobby does not feature a separate tab for video poker but this is not to say it lacks options for fans of this strategy game. Some of those can be found under the Table Games tab. They offer some of the lowest house edges you can possibly find at a casino, especially when one incorporates a correct strategy.

Microgaming supplies All Aces Poker where you can wager up to five coins per hand, with denominations ranging from £0.25 and £5. The gamble functionality activates after every winning hand, giving you the chance to double, treble, or quadruple your payoff. The paytable contains additional payouts for certain four-of-a-kind combinations.

Also available at 21Casino is NetEnt’s Jack or Better Double Up. This is the full-pay version where you can play between 1 and 25 hands simultaneously.

Range of Progressives

Range of Progressives

  • Mega Moolah
  • Mega
  • The Naked Gun
  • Major Millions
  • Rainbow Jackpots

The jackpot tab of 21Casino contains around 40 distinct slot titles with huge winning potential. The most lucrative progressives are courtesy of Microgaming and NetEnt. The two providers have supplied 21Casino with jackpot classics like Mega Joker, Mega Moolah, Mega Fortune, Hall of Gods, Treasure Nile, Tunzamunni, Lotsaloot, Cash Splash, Fruit Fiesta, Major Millions, and Divine Fortune.

Players can also get their adrenaline pumping in Pirates’ Plenty by Red Tiger Gaming, which offers Hourly, Daily, and Super jackpot drops. The list of progressives is complete with Reel King, Rainbow Jackpots, The Naken Gun, Irish Riches, and Patrick’s Jackpot, among others. Customers based in Japan, India, Tunisia, and Malaysia are not eligible to play progressives at 21Casino.

Selection of Live Dealer Tables

live dealer

  • Casino Hold’em
  • Caribbean Stud Poker
  • Super Sic Bo
  • Lightning Roulette
  • Dragon Tiger

Head over to 21Casino’s live section where you can join the attractive dealers of Evolution Gaming and NetEnt for some authentic betting action. The live tables operate around the clock so you can hop in whenever you feel like it.

Poker buffs face a decent choice from Ultimate Texas Hold’em, Texas Hold’em Bonus, 2 Hand Casino Hold’em, Three Card Poker, Casino Hold’em, and Caribbean Stud Poker. There are tables for all preferences, including Dragon Tiger, Super Sic Bo, Live Blackjack, Live Baccarat, and Lightning Roulette.

Evolution provides 21Casino with several unorthodox live options that play more like game shows rather than traditional casino games. Give your luck a test drive in Crazy Time, Dream Catcher, Deal or No Deal, Mega Ball, and Football Studio.

Mobile Experience & Apps

Mobile Experience & AppsBeing cross-compatible, 21Casino ensures a seamless experience to both desktop and smartphone players. The website adapts well to touchscreen devices, giving you instant browser access to a broad range of superb casino games.

The web app supports all the main functionalities of the desktop version of 21Casino. It uses the trademark black and gold design, with promotional banners on top and the navigation tabs at the button, leading you to the homepage, the lobby, and the search box. The main menu is located at the lower right corner of your touchscreen.

The casino is yet to launch native apps for Android and iOS but adding it to your home screen is an option if you want quicker access. The browser-based mobile version is multilingual. You can load it in English, Finnish, and Norwegian. It comes equipped with a live chat.

The mobile lobby boasts a clean and well-structured design. Games can be filtered by software provider or category. Mobile players will come across all their favourite slot releases including Rise of Olympus, Gonzo’s Quest, Jammin’ Jars, Reactoonz, Piggy Riches, Moon Princess, and Viking Runecraft.

Plenty of options are available to those who prefer table games. They can play 3D Baccarat, European Roulette, Single Deck Blackjack, Casino Hold’em, and more. Smartphone users have on-the-go access to Evolution Gaming and NetEnt’s live tables as well.

Promotional Incentives

UK players who register at 21Casino are in for a bright start as the operator offers a fantastic sign-up offer. Returning customers are not left with empty hands, either. The free fun continues with various one-off promotions. The royal loyalty programme also helps active customers to build up their bankrolls.

New Player Bonuses

New Player BonusesNewbies at 21Casino are off to a flying start with a nice welcome bonus that matches their first deposits by 121% with up to £100 in bonus credits. You need to load at least £10 into your new account’s balance to become eligible for participation in the offer.

UK players who have redeemed the bonus can cash out whenever they like but at the expense of having their free credits revoked. This would result in the removal of the bonus and any associated profits. UK customers can avoid this by clearing the 35x wagering requirement before they request a withdrawal. The playthrough applies to the value of the bonus only.

Another thing to bear in mind is that you have 30 days after the bonus redemption to clear the above-specified rollover. If you fail, your welcome bonus will again be forfeited by the casino. Make sure you do not violate the maximum bet limit that applies to playing with an active bonus. Your wagers prior to clearing the rollover should not exceed £5 per hand/spin.

Also important to specify is that different games contribute differently to your wagering requirements. Slots, keno, and scratchcards have the highest weighting toward the playthrough at 100%.

There are exceptions for Extra Chilli, Arcade Bomb, Da Vinci, Forsaken Kingdom, Dead or Alive 2, Zombie Hoard, Tomb Raider, The Wish Master, and a bunch of other slot releases that have a contribution of 20% only. Progressives have no weighting towards the bonus wagering whatsoever whereas table games contribute only 10%.

Bonuses for Returning Players

Bonuses for Returning PlayersThe operator does not restrict its generosity to newbies only. Existing customers can indulge in extended free play by opting in for various limited-time promotions. These become available after newbies redeem and play through their welcome bonuses. Some of the offers are limited exclusively to specific gaming categories such as slots.

It would be best for players to check their email inboxes along with the promotional section of 21Casino to stay abreast of the latest available incentives. Under the operator’s general terms and conditions, all bonus amounts granted to returning players must be wagered 35x before they are converted to withdrawable cash in the real-money balance.

The casino sometimes advertises bonus spins on specific slot games. Such offers come with restrictions on the cashable winnings which are capped at £100. Any profits in excess of this amount are removed from the player’s balance upon withdrawal.

Winnings generated through the use of bonus spins do not contribute towards the clearing of the wagering requirements. Free spins at 21Casino generally expire after 10 days counting from the day of redemption.

Loyalty Rewards and Comp Points

Loyalty Rewards and Comp PointsThis UK-facing operator likes to give its customers the royal treatment by enrolling them in its loyalty programme. This allows them to generate comp points for each real-money stake they place with 21Casino. Each customer must build up to a minimum of 200 loyalty points before they can convert them to bonus credits.

The exchange rate is £1 for 200 points. The most you can exchange per day is 10,000 points, which translates into a £50 bonus. As for accumulation rates, these are game-specific. Every £10 wagered on the scratchcards and the slots result in 2 points. Video poker and bingo earn you 1 point for each £10 stake whereas blackjack and roulette earn you 0.50 and 0.25 points.

The general bonus terms of 21Casino stipulate that you might have some of your points revoked if your account remains dormant for 30 days or more. Bonuses redeemed through points conversion are subject to the casino’s standard playthrough requirements.

Casino Cashier

Depositing players face a number of secure payment methods at 21Casino. All British customers must undergo verification checks to confirm their age, identity, and banking solution before they can transfer any real cash to their balance. Other than that, payments at 21Casino are generally very safe and free from any hassles.

How to Deposit at 21Casino

How to DepositUK registrants at 21Casino can transfer funds to their balance with popular methods like debit cards, virtual wallets, prepaid solutions, and standard transfers. Unfortunately, the operator offers very scarce information about the supported deposit channels. There is no payment methods table anywhere on the website.

No information regarding the limits on deposits is available either, not even in the general terms and conditions of the casino. A little bit more transparency in this respect would be great for players who have not yet decided what deposit method would be best for them.

With that said, we chatted with the support staff of 21Casino and they told us the minimum transferable deposit amount is £10, same as the requirement for redeeming the welcome bonus.

The reps informed us players can deposit with debit cards by the brands Visa, Mastercard, Maestro, Trustly, Paysafecard, Neteller, Skrill, PayPal, Boku, MuchBetter, Interac Online, and bank transfers. No fees are charged by 21Casino for deposits.

How to Withdraw from 21Casino

How to WithdrawWinning customers at 21Casino can cash out their gains with most of the solutions used for deposits. For quick withdrawals, we suggest you use the digital wallets Skrill, Neteller, and PayPal. Also accepted are debit cards by Visa, Maestro, and Mastercard. Bank transfers are supported as well.

UK customers should be careful when they select a deposit method because the casino returns withdrawals to the same banking solutions they have initially used to top up their balance. The information regarding withdrawals and available methods is again scarce on the website.

Once you register and make a successful deposit, the accepted withdrawal methods will become available to you. You can check them out after logging in and navigating to your account’s dashboard. The smallest amount you can cash out from your 21Casino balance is £10. The maximum per week reaches £25,000. This cap is lifted for progressive jackpot wins.

Customers who have achieved VIP status are eligible for an increase of their maximum withdrawal limit. Once players request a withdrawal, it will remain pending in their accounts for 1 to 2 working days, during which time the casino’s financial department will process and approve it. After the funds are released from the balance, they will reach you within up to 5 working days.

The exact waiting time varies depending on what payment method you have selected. UK customers must register their accounts in GBP while players from other countries have a choice from several other options including USD, AUD, CAD, and EUR. You should play in EUR if our local currency is unavailable or else your winnings will be forfeited in favour of 21Casino.

Licensing & Overall Industry Reputation

Licensing & Overall Industry ReputationThe casino is property of White Hat Gaming Limited, a company that hails from Malta. The website is legally accessible from a variety of countries. It carries a license from the Maltese Gaming Authority. Its operations in the United Kingdom are conducted with the permission of the UK Gambling Authority while those in Sweden are overseen by Spelinspektionen.

The license numbers are pinned to the website’s footer so that players can easily check the permits’ status. Licensing restrictions prevent the casino from servicing customers from certain locations including the USA, Belgium, France, Bulgaria, Italy, Hungary, Israel, Denmark, Latvia, Portugal, Singapore, Poland, Russia, Spain, Romania, South Africa, Slovenia, Turkey, and Switzerland.

The UKGC wins the race where strict regulatory oversight is concerned so it only makes sense 21Casino enjoys a fine reputation on the British market. We did not find any serious player issues or complaints regarding the operations of this casino. If you experience any problems, though, you can address them by submitting a complaint to eCOGRA or The POGG, the Alternative Dispute Resolution (ADR) providers of 21Casino.

Responsible Gambling and Player Protection

Responsible Gambling and Player ProtectionUnder the regulations of the UKGC, 21Casino strives to motivate players to gamble more responsibly by offering them a choice from various responsible gaming tools. You can self-impose daily, weekly, and monthly limits on your deposits. A limit increase comes into effect after 24 hours while a decrease is instantly effective.

Players can also set duration limits on their gaming sessions. Automated hourly reality checks are also available. Customers can take advantage of temporary breaks and permanent account closure by contacting the customer support team. Links to organisations like Gambling Theory and Gamcare are posted in the footer.

The casino uses the industry-standard SSL encryptions to safeguard its customers’ personal and financial information. It complies with UKGC’s requirement for segregation of players’ funds at a “not protected” level, which means there is no guarantee customers will get their money back if the company declares insolvency.

Customer Support Service

Customer Support ServicePlayers at 21Casino will benefit from quick assistance provided by support representatives that are on stand-by 24 hours a day throughout the entire week. Contacting the team is made simple by the availability of a live chat facility. Just click or tap the yellow button in the lower corner of the screen and you are there.

Our impression was that they rarely take more than a minute to respond to queries but the waiting time might vary if there are other players in the queue. If you do not feel like chatting, you can easily email them at support@21casino.com. They usually get back to you within the same day.

Closing Thoughts

Closing ThoughtsAltogether, 21Casino has earned our endorsement for its rich selection of games, adequate responsible gambling policies, quick support service, and uncluttered interface. We would like to see more transparency when it comes to payments on this website.

In our opinion, potential customers will benefit from the ability to compare different banking solutions so they can make more informed decisions when choosing a method. Manual flushing instead of withdrawal reversals would also be great. Other than that, 21Casino has earned the approval of our team of reviewers due to its many merits.
