Get a welcome bonus of 121% up to £300

Before we check out 21 Casino’s games selection and live casino, we’ll take a look at its generous welcome bonus. Most UK casinos offer its new players a 100% welcome bonus, but 21 Casino has prepared an even sweeter deal for their first time depositors. When you create an account and visit the cashier, you can grab a 121% welcome bonus on top of your first deposit:

Get a 121% bonus up to £300 on your first deposit


The first deposit bonus more than doubles your first deposit, and you just need to deposit £10 or more to activate it. If you’re wondering how much you need to deposit in order to maximise the offer and get the full bonus of £300, the answer is £247 (we did the math on this one). The bonus will be added to your deposit as soon as you have completed the deposit process, and then you will be able to play your favourite games immediately.

21 Casino’s excellent welcome bonus will give you a great start in the casino. The bonus plus deposit must be wagered only 35 times before you can make a withdrawal. For example, if you deposit £100 and get a bonus of £121, you need to wager £7735 in order to complete the wagering requirements. The good news is that the deposit and bonus are separated into two wallets. You play with your real money first, and you only start using bonus money if you lose the initial deposit amount. This means that you can cash out your deposit and winnings whenever you want as long as you haven’t played with the bonus funds. If you withdraw from your real money balance, you will of course forfeit the bonus. Bonuses like these are often called parachute bonuses, as they give you a second chance if you lose your deposit.

When you play with bonus money, you need to keep the bonus terms and conditions in mind. As usual, we’ll list a few of the most important terms here – but we recommend that you read the full terms and conditions on 21 Casino’s bonus page. First of all, you can only bet up to £5 per bet while playing with bonus funds, regardless of the game. The vast majority of the hundreds of slots in 21 Casino’s games lobby can be played with bonus money, but there are some exceptions. For example, you can not play jackpot slots as long as you play with an active bonus. We recommend checking the list of restricted slots and other casino games in the bonus terms so that you don’t play any of them by accident.

The wagering requirements of the welcome bonus must be completed within 30 days after you received it. Once you have played through the bonus and deopsit 35 times and finished the wagering, you can play any of the games on the site or cash out your full account balance. Note that wagering contribution only starts when you play with the bonus money, so the wagering won’t decrease while you play with your real money deposit. The 121% welcome bonus is just the beginning of the incredible bonuses and rewards you’ll receive at 21 Casino, and you can learn more about the bonus and wagering requirements by heading to the casino’s promotions section.

Unique loyalty program with fantastic rewards

21 Casino’s loyalty program is perhaps one of the best things about the site. We at BestCasino always appreciate these types of programs as they reward players with extra bonus cash, free spins or other casino goodies. Picking an online casino that has a generous loyalty program can be highly beneficial since the rewards can make a huge difference in the long run. 21 Casino’s loyalty program is called Loyal Royalty, and it can give you tons of extra rewards as you play your favourite games.

With the loyalty program, you automatically earn points as you play any of the games in the casino. These points can be exchanged to bonus cash when you have saved up enough of them. The coolest part is that you can play any of the hundreds of games in the lobby and collect points – whether you prefer slots, table games, video poker or something else. However, you should note that you get different amounts of points for playing different games. For every £10 you wager on slots, you will get 2 loyalty points. If you’d rather play video poker, you’ll get 1 point for wagering the same amount. Blackjack gives you 0.50 points, and roulette gives you 0.25 points for every £10 wagered. You can check the full point scale on the casino’s loyalty page. The quickest way to rack up loyalty points is by playing slots, but other games will also boost your points balance over time.

Many casinos have similar loyalty programs that give you points that can be exchanged to bonus cash, but 21 Casino does things a bit differently. Instead of giving players bonus cash or points based on their account level, everyone gets the same amount of bonus money for the same amount of points. It works like this: exchanging 200 points will give you £1 in instant bonus cash. This means that if you exchange 5,000 points, you will receive a £25 instant bonus. You will get 200 points by wagering £1000 on slots, giving you a nice bonus cashback over time. You can exchange up to 10,000 loyalty points per day, and the minimum exchange amount per transaction is 200 points. The bonus cash has a wagering requirement of x35, and there are no maximum withdrawal limits. Make sure to keep an eye on your points balance by visiting your account frequently, and use them to boost your balance whenever you need it.

In addition to the excellent loyalty program, you can participate in valuable casino promotions every week. There are often new giveaways, competitions or deposit offers available, and you can come back every week to grab the weekly reload and free spins offers. The Stairway bonus is available every weekend, giving you a chance of picking up to 150 free spins on some of the most popular NetEnt slots when you make deposits throughout the weekend. And during Mondays and Tuesdays, you can log into your account and activate a sweet 21% bonus up to £210 when you make a deposit. These fantastic promotions are available every single week, and 21 Casino loves mixing things up with fresh giveaways and promos every month. Keep an eye on the newsletters and on the promotion page to not miss out on a great deal. With frequent casino offers and the generous loyalty program, there is always something fun to look forward to while playing at 21 Casino.

Play hundreds of slots from over 80 game providers

The games lobby of 21 Casino is packed with hundreds of slots from world-leading game providers. There are over 80 game providers in place, which is two or three times more than what most online casino sites have. All the major game providers are available, but you will also find tons of niche slots from much smaller studios that you won’t find on many other sites. This means that not only can you enjoy all your favourites, but you can also explore and discover a range of innovative slots while scrolling through the never ending list of games. To get you started, here are some of the best game providers at 21 Casino:

  • NetEnt: No casino is complete without the high-quality games from NetEnt. NetEnt is a Swedish game developer that makes some of the most advanced video slots on the internet, with fantastic graphics and exciting bonus features. Whether you are a new player or an experienced gambler, we bet you will love NetEnt games such as Asgardian Stones, Coins of Egypt, Wild Worlds, Dead or Alive 2 and Narcos.
  • Microgaming: Microgaming is an old-school game provider that has been making online slots for over 20 years. This gaming giant operates everything from game studios to sportsbooks and a poker network, and they have paid out over £1 billion in online jackpot prizes over the years. Most modern Microgaming slots are available at 21 Casino, which means you can check out great games such as Wild Orient, Wacky Panda, Terminator 2, Fortunium and Playboy Gold.
  • WMS: You can find the popular slot machines from WMS Gaming in real casinos all over the world. The company was founded as early as in 1943, but it went from producing arcade games and pinball machines to making casino games in the mid-nineties. Today it is a part of the gaming group SG Gaming, and they produce new slot machines for online casinos. Some of our favourites are Knight’s Keep, Bruce Lee, Kronos, Giant’s Gold and Monopoly Big Money Reel.
  • Big Time Gaming: Big Time Gaming has quickly become a must-have game provider at any online casino. This Australian gaming studio revolutionised the gambling world when they introduced the Megaways reel setup a few years ago. They don’t release as many games as some of the game providers on this list, but their slots are always worth waiting for. Some of the best BTG games are Opal Fruits, Starquest, Donuts, Bonanza and The Final Countdown.
  • Play’n GO: Looking for innovative slots with unique features and bonuses? Look no further than Play’n GO. This Swedish game provider has become a leading game provider because of its ability to always come up with something brand new and fresh. There are over 60 Play’n GO games to choose from in 21 Casino’s games lobby. Don’t miss out on some of their top slots such as Wild Blood, Legacy of Egypt, Gold King, Inferno Star and Pearls of India.
  • Blueprint: Blueprint Gaming is one of the UK’s biggest game providers. The company makes slots for online casinos and for thousands of betting terminals across the country. Many of their games are based on popular films and TV shows, and they have also made several innovative slots with Big Time Gaming’s Megaways setup. Here are some of our favourite Blueprint games: The Goonies, Diamond Mine, Genie Jackpots, Valletta Megaways and Fortunes of Sparta.
  • Red Tiger: Few game providers can match Red Tiger’s creativity and passion for making innovative slots. The company was founded in 2014, but it has already made dozens of fantastic slots for hundreds of online casinos. Their games are packed with exciting bonuses that can pay out massive wins to lucky players. If you want to give them a go, we recommend great slots such as Dragon’s Fire, Vicky Ventura, Jack in a Pot, Totem Lightning and Ninja Ways.
  • Relax Gaming: Relax Gaming was founded in 2010 with the goal to push the boundaries of online gambling. The company offers everything from poker and bingo games to video slots, and they make their own slots as well. If you haven’t checked out Relax Gaming yet, we recommend playing some of their latest releases: Temple Tumble Megaways, Ignite The Night, The Great Pigsby, King of Kings and Money Train. You can find many more Relax Gaming games over at 21 Casino.
  • Quickspin: Quickspin has gone from being a small game studio to a leading game provider in less than a decade. Today, you can find their vibrant video slots at most UK casinos on the internet. That’s a great thing since their games are a blast to play for all types of players. If you love high-quality slots with fantastic graphics and sound design, you can’t go wrong with fantastic Quickspin slots such as Joker Strike, Sticky Bandit Returns, Durian Dynamite, Rapunzel’s Tower and Prime Zone.
  • ELK Studios: We are always looking forward to the next slot release from ELK Studios. This Stockholm-based game providers have won awards for their innovative games, and they continue to put out incredible games with fun features and bonuses. The full ELK Studios portfolio is available at 21 Casino, which means that you can enjoy some of their best slots: Tahiti Gold, Route 777, Lake’s Five, The Wiz and Platooners, to name a few.

These are just 10 of the 80+ game providers that are listed at 21 Casino. If you’re looking for something new, we highly recommend checking out smaller game providers such as Cayetano, Red 7, Chance Interactive, Fantasma, Leander, Foxium and STHLM Gaming as well. The games lobby has a useful filter that lets you find the slots of specific providers, so you can use it to find the games that you wish to play. There are so many fantastic games at 21 Casino that you will never be able to play all of them, and new slots are added every week!

Some of the biggest jackpots in the world can be won at 21 Casino. Not only will you find the popular jackpot slots from NetEnt and Microgaming here, but the jackpot games from several smaller providers are also in place. This means that you can hunt the millions in famous games such as Mega Moolah, Mega Fortune and Hall of Gods, or try your luck in unique jackpot slots such as Vikings of Fortune, Apollo, Tiki Treasures or Slots O’ Gold. Click on “jackpot slots” in the header menu to quickly see a list of all the jackpot games.

If you are in the mood for some classic table games, you can play all your favourites here. The “table games” category has blackjack, roulette, punto banco, casino poker and tons of variations of these iconic games. All table games are listed in the “table games” and “other table games” categories in the lobby browser. There are also several scratch cards and bingo games available, and you can play common video poker games such as jacks or better, aces and eights, deuces wild and joker wild. Of course, 21 Casino has a world-class live casino that is powered by Evolution Gaming as well, and we will look at these games in the next part of the review.

21 Casino’s live casino is powered by Evolution Gaming, the world’s leading live casino company. Evolution has offices all over the world, and thousands of employees are working on creating the best live casino experience the internet has to offer. The full range of Evolution’s live games is available at 21 Casino, which means that you can enjoy everything from blackjack and roulette to Dream Catcher and Lightning Roulette. Here’s a list of all the live games that are currently available in the casino:

  • Roulette
  • Blackjack
  • Baccarat
  • Super Sic Bo
  • Lightning Roulette
  • Casino Hold’em
  • Ultimate Texas Hold’em
  • Three Card Poker

  • Caribbean Stud Poker
  • Texas Hold’em Bonus Poker
  • Dragon Tiger
  • Football Studio
  • Dream Catcher
  • Monopoly Live
  • Deal or No Deal

Some of the classic table games have several variations. For example, you can play speed roulette if you want a more action-packed experience, or you can check out double ball roulette which is played with two roulette balls for twice the fun. There are dozens of blackjack tables open 24 hours a day which means that you will always find a free seat, but you can play on the infinite blackjack table if you don’t want to play with other players. Every player is dealt the same starting hand, which means that you don’t have to wait for your turn to act. There are many other game types and variations, and we recommend checking them out if you want to try something new and fresh.

One of the reasons why Evolution Gaming is so successful is their range of exclusive games. Their game shows have changed the online gambling scene, and some of their most popular games have thousands of players every day. Their first game show game was Dream Catcher, a thrilling wheel game with a unique concept and massive multipliers. This was followed by Monopoly Live, a similar game that has a bonus mode where you run around a Monopoly board to pick up cash prizes. There are many other unique live casino games at 21 Casino, such as the dice game Super Sic Bo, Football Studio, and Deal or No Deal – a casino version of the classic game show that you’ve probably seen on TV.

No matter if you are a high roller or a regular player, there are many tables to choose from. VIP players who enjoy placing bets of thousands of pounds can take a seat at the exclusive VIP tables with high limits, but you can also play on blackjack and roulette tables where you can bet as little as one pound per round. There is something for everyone here, so make sure to look for tables that are within your gambling budget. All of Evolution Gaming’s live casino games are streamed in full HD, and they are optimised for both mobile and desktop.

User-friendly website with a classy design

The website’s performance and user-friendliness is an essential part of any online casino. Nobody likes playing laggy games on a website that is difficult to navigate. 21 Casino is a modern casino that has all the features you could wish for, and the website is extremely simple to use. The dark and sleek design works well for the user experience since all the games and menus are highlighted and easy to find on all platforms.

When you log in to your player account, you will see your personal dashboard. This section gives you a quick overview of everything you need to know: your total balance, your active bonus, your favourite slots and your last played games. You can also get information about the current promotions at the top of the page. If you click on “account” in the top menu, you get access to more options and settings. On your account page, you can deposit and withdraw, check your transaction history, edit your account details, see your bonus history and exchange your loyalty points into bonus cash. The usual responsible gambling tools are also in place so that you can set a deposit limit, session limit or pause your account.

21 Casino has hundreds of slots from over 80 game providers, so it needs to have a robust games lobby that lets you find the games that you wish to play. To access the games lobby, click on “games” in the top menu. The games are divided into categories such as top games, new games, slots, live casino, table games, jackpot games and more. If you are logged in, you will also get “last played games” and “favourites” here too, making it easy to get back to the games you love the most. Once you have clicked on a category, all the games will appear in a long list. Scrolling through the list of slots may take a while since there are so many of them, so we recommend using the filter feature to find games by specific game providers.

The games lobby has a couple of other neat features. If you activate the “show RTP” setting in the filters, the game’s RTP will appear when you mouse over it. Since you should always pick games with high RTP, this can be very helpful – especially if you don’t know anything about the slot or the game provider behind it. You can also mouse over the game icon to check the paylines, reels and volatility. When you click on the little heart icon on the game icon, it is instantly added to your favourites for quick access. The slots run smoothly, and we never experienced any annoying lag or delays when testing the site. The games open in seconds, and you can play them in fullscreen if you want a more immersive experience. 21 Casino’s website works great on both desktop and mobile, so you can enjoy your favourite games wherever you go.

24/7 customer support via live chat and email

21 Casino’s friendly customer support is ready to assist you whenever you have a question or need help. To chat with the support, simply scroll down and click on the white live chat button at the bottom of the page. A small window will appear in the bottom right corner of your screen, and a customer support agent will be in touch as soon as you click on the connect button. You don’t have to be logged in to use the live chat, and we never had to wait more than a minute for an answer.

The live chat is open 24 hours a day, 365 days a year – always ready to help you with whatever you might need. The website doesn’t offer phone support at the moment, but you can also send an email to [email protected] to get an answer by email. We hope 21 Casino add phone support in the future, as some players prefer to talk with a real human over the phone. A FAQ page would also be handy, but you can still find quite a lot of general information on the page.

Secure deposits and fast withdrawals

When you are ready to make your first deposit, you can choose from many payment methods. Making a deposit is quick and easy. Simply click on the orange deposit button in the top right corner of the website when you are logged in to get started. Once you have selected your deposit amount and clicked next, any available bonus will pop up. If you are making your first deposit, you can click on the welcome bonus to activate it on your deposit. The website has many payment options, including credit cards, bank transfer, Skrill, Neteller and Paysafecard. Simply choose your payment option and enter your details to complete the deposit. The money will appear on your account immediately unless you use bank transfer.

Making a withdrawal is also very straightforward. Go to your account and click on withdraw to choose your withdrawal amount and payment method. You can withdraw from your cash balance whenever you want, but remember that this will forfeit any bonus and bonus winnings. Once you have completed the withdrawal, 21 Casino’s payment team will manually process your withdrawal. This may take a few hours or a day, depending on the withdrawal queue. If you have any questions or need any help, you can always get in touch with the 24/7 live support.

21 Casino is licensed by the UK Gambling Commission and Malta Gaming Authority, and your withdrawals are tax free. Since 21 casino is a licensed and trustworthy casino, you might need to verify your account before you can make withdrawals. You can learn more about account verification by visiting the verification procedure page on your account.
