21 Casino was established in 2015 with the aim of providing the ideal playground for serious players.

Set against a grey background and refined with casino symbols, including dice, chops, cards and a Roulette wheel, our menu is embellished with bright-coloured accents.

I found 21 Casino to be a pretty solid place to spend some time but was concerned the simple design here could be boring. The overall vibe of luxury leaning towards opulence, has translated in all aspects of the site. Simplicity can be a virtue, but some might find it dull.

I enjoyed the crisp, no-nonsense design of the site, and it was very easy to find my way around on both desktop and mobile. There are only 5 items in the main menu with all of the game options living in a sub-menu on the casino page. I was given the option of downloading an app when playing on my Mac. This was a Chrome browser app which gave me a nice stripped-down window with no distractions.

Signing up to 21 Casino was a pretty painless process with some well-designed forms to fill in. After entering the regular personal details such as address and phone number, I had to verify my email address by clicking on the link they sent me. This took me back to the ‘My 21' page, which is where all my recently played games are displayed alongside any bonus details. It did seem unusual that there was no prompt to make my first deposit during signup, but refreshing that I wasn't .

Needless to say, their promotions are enticing, covering a wide spectrum of gaming options with delightful treats.

With dual-licenses from the UK Gambling Commission and Malta Gaming Authority as well as a reliable SSL encryption in place, 21 Casino has ticked all the right boxes in safeguarding your interests and personal data.

21 Casino first deposit bonus

Get a head start with a fantastic first welcome bonus. Get a no-deposit bonus and a second bonus deal when you make a minimum deposit of £10.

18+. New players only. Min deposit £10. Bonus funds are 121% up to £100. Bonus funds are separate from cash funds and subject to 35x wagering requirement. Only bonus funds count towards wagering contributions. £5 bonus max bet. Winnings from No-Deposit Spins capped at £100.Bonus funds must be used within 30 days, spins within 10 days. Affordability checks apply. Full and Bonus terms apply.

You can enjoy lots of great bonuses at 21 Casino. Your first bonus is an exclusive special deal that is only for Bojoko users. Go to the casino from this page, and you can claim:

  • 21 free spins on Book of Dead without a deposit

Then when you decide to make your first deposit, you can get the rest of the bonus offer. With as low as £10 deposit you are entitled to the welcome bonus of

  • 121% match bonus up to £100

If you are ready to get started follow the below steps to claim your welcome offer:

  • Sign up for a 21 Casino account
  • Verify your account by email
  • Make a minimum deposit of £10
  • Your welcome offer will be credited to your account

I found the 21 Casino bonus easy to understand and the the bonus funds showed up as a separate balance in the top left of the screen. Clicking on ‘Bonus Details' under the ‘Account' menu, I was able to see the full details of my active bonus. As my bonus was used, the table updated so that I could track the progress and wagering in real-time. In addition to this, my bonus progress was shown at the base of the main ‘My 21' homepage.

Wagering wise, it comes in at a pretty average thirty-five times 35x (B). When looking at the small print, there is a pretty large list of games which contribute little or zero to the wagering requirements of the welcome offer. It's definitely worth looking at if you are going to take this on and remember that it must be met within 30 days.

Looking beyond the welcome offer, I can see that there are some decent reload bonuses and free spin offers to keep me coming back here. There's also a loyalty point scheme where you get 2 points for each £10 wagered on slots. I worked out that I'd get £1 in bonus money for each £1,000 I play. I'd then need to wager my £1 bonus 35x which seems like a pretty raw deal to me.

Despite the name, 21 Casino is not just about online blackjack games. They have one of the most versatile slot collections in the UK, which come in a variety of themes, reels and gameplay.

Once my deposit was taken care of, I headed straight over to the slots selection. Under the ‘Games' menu, things are divided up into neat categories such as ‘New', ‘Top', ‘Slot', ‘Table', ‘Jackpot' and ‘Live' plus a full list to filter by developer only.

The game catalogue is powered by Big Time Gaming, Evolution Gaming, Merkur, NetEnt, Microgaming, Thunderkick, Leander, Red Tiger and Barcrest amongst many others.

Jackpot fans can rejoice aplenty, with numerous gaming options, including Mega Fortune, Divine Fortune, Hall of Gods, Mega Joker and Lion Festival.

Alternatively, players can available themselves of our numerous table games, including the likes of blackjack, roulette, video poker, bingo and scratchcards.

After testing out the games, I was pleased with the quality and speed. I found that all games loaded quickly and played without causing any issues or glitches.

When it comes to playing on the go, 21 Casino has made sure that the players have access to a fantastic mobile casino anytime they want. You can access to numerous games via your smartphone or tablet, regardless of whether they are operating on an iOS, Android or Windows system.

With the lack of a dedicated Android app, I loaded the casino site in the Chrome browser on my OnePlus phone. Here I found one of the best designed mobile casino sites I've seen in quite a while. With a clean 4 item menu at the base of the screen, I found it very easy to navigate around with no glitches and the full functionality of the desktop site. Confusingly, the player menu does have an ‘Install App' button, but this just adds a home screen shortcut.

You can enjoy a superb collection of slot games, table games, live casino games, scratchards and more, without having to download a mobile casino app. Since the games are available in instant-play mode, you can play straight from your mobile web browser.

Besides playing games, you can make deposits and withdrawals and get in touch with the customer support services.

21 Casino accepts a wide array of banking methods. You can make a deposit and withdrawals with one of the following methods:

  • Debit Cards
  • EWallets
  • Prepaid Vouchers

After I'd signed up and logged in as a new player, I went to make a deposit right away. There was a line confirming that the minimum deposit is £10 and there are zero fees charged.

I selected Visa Debit and entered the amount of £40. Before confirming, I had the option to check the welcome bonus offer which I did to test it out. There was also a box to tick to confirm that I understood their customer funds protection policy. Once I'd passed the ‘Verified by Visa' check, I got a pop-up confirmation to say that my deposit was a success. The £40 real cash funds and bonus funds cash showed up instantly. I also got an email confirming my full deposit details which was reassuring.

When I requested a withdrawal of my winnings, I instantly received an email which said, ‘Your withdrawal will stay pending for approximately 2 days. This is a memento from the time you could reverse your withdrawal, which has not been legal for a while.

It took 28 hours for my withdrawal to be approved, and the funds arrived in my bank account around 4 hours after approval. I can't fault 21 Casino here, the process was smooth, speedy and I was kept informed at all times via email.

Getting in touch with 21 Casino is easy. The Customer Support team is available around the clock, 24 hours a day, 7 days a week.

I fired up the Live Chat window when I was using my mobile browser to see if the team could answer my question about making a withdrawal. The chat was answered in a very speedy 5 seconds, and the agent was polite with her answers. The one minus point was their initial template reply informing me that I didn't qualify for a bonus at this time. They apologised and said it was a genuine error, but everything was good otherwise. There was also the option to email a transcript of the chat when closing the window.

The real bugbear, when it comes to support at 21 Casino, is the blatant lack of an FAQ page in any form. The ‘Contact Us' page just has a live chat button and the support email address but nothing else. I think they would have a lot of unnecessary chat requests by providing at least some basic player information on the site. That said, there was a comprehensive page on responsible gambling and controls under my ‘Account' menu.

21 Casino is obliged by law to confirm the identity and age of their players.

Whenever they are unable to verify information automatically, they'll request for you to send in the following documents:

  • Proof of ID (passport, driving license, ID card)
  • Proof of address (utility bill, bank statement, official government letter)
  • Proof of Payment Method

Even with automatic verifications, there was no proper mention of any potential checks or verification required. It was unusual not to see at least something mentioned in the welcome emails or signup process. I also couldn't find any mention of KYC procedures or policy anywhere on their site despite a good sniff around. The lack of a FAQ section didn't help this search either.

In the end, everything worked like a charm, but it was all done without my participation. This was handy and made things easy, but felt strange when you are used to in-your-face verification messages.

21 Casino wants you to have fun and to enjoy their products. If online gambling stops being fun and starts eating into your expenses, it is their duty to help curb down compulsive usage.

They have added the following options to give you better control over your spending:

  • Deposit Limits
  • Game Time Reminder
  • Account Closure
  • Time-Out
  • Access to Account History
  • Self-Exclusion

There are many organisations which can help and support players with problem gambling.

If you feel, you or a loved one have a problem controlling your gambling, you can get in touch with BeGambleAware, GamCare or Gamblers Anonymous.
