Promotions And Bonuses

21 Welcome Bonus

Like so many other online casinos, 21 Casino is running a generous welcome bonus where you can claim a 121% match bonus of up to £300 with a minimum £10 deposit. According to 21 Casino UK, the bonus funds need to be wagered 35x before anything can be withdrawn. This must be completed within 30 days of being credited to the bonus or it expires.

Promo Code

While some online casinos now require you to enter a promo code in order to successfully claim a promotion, this site does not. There are no 21 Casino promo codes as all bonuses are automatically credited to your account once you’ve fulfilled all requirements.

21 Free Spins

Many of you have been asking about the 21 Casino 21 Free Spins promotion but, at the time of writing, the site is not offering this. While this may be disappointing, the online casino does offer a range of other promotions and bonuses which are worth looking into.

£20 No Deposit Bonus

There currently is no 21 Casino £20 no deposit bonus. This is because the site offers a welcome bonus, as detailed above, which requires a minimum £10 deposit. If you’re looking to join an online casino offering a no deposit bonus, it’s best to look elsewhere.

Other Promotions

In addition to the welcome bonus, 21 Casino UK is currently running several other promotions. At the time of writing, this includes the Reel Royale, where players can win a share of £5,000.

Loyalty Scheme

21 Casino UK also runs a loyalty scheme where you can redeem loyalty points for real cash. As you play at 21 Casino, for every £10 wagered on casino games, you’ll earn the following loyalty points:

Slots: 2
Scratchcards: 2
Video Poker: 1
Bingo: 1
Blackjack: 0.50
Roulette: 0.25

Once you’ve accumulated 200 loyalty points, you can redeem them for £1 in cash. The maximum amount of loyalty points you can collect is 10,000 in one day and all bonus cash redeemed from loyalty points must be wagered 35x before it can be withdrawn.

Payment Options


21 Casino UK accepts most major payment methods, allowing users to deposit and withdraw in their preferred methods. At the time of writing, they include:

  • VISA/MasterCard: Available instantly
  • Skrill: Available instantly
  • Neteller: Available instantly
  • Trustly: Available instantly
  • Bank Transfer: Available instantly
  • PayPal: Available instantly

Unlike many other online casinos, 21 Casino does not charge you for making deposits or withdrawals.

21 Withdrawals

With the exception of Paysafecard, you can use all of the above payment options for deposits. However, the time it takes for these payments to reach you depends on the method used, for example:

  • VISA/MasterCard: Between three to five business days
  • Skrill: Up to 48 hours
  • Neteller: Up to 48 hours
  • Trustly: Between three to five business days
  • Bank Transfer: Between three to five business days
  • PayPal: Up to 48 hours

It’s important to understand that the online casino uses a source to source policy for withdrawals, which means you can only withdraw through the same method used to deposit. So if you decide to deposit via VISA debit card, you’ll only be able to withdraw through that method later on.

Account Verification

Under rules by the UK Gambling Commission, all new users who register at an online casino must verify their address instantly. To do this, you’ll need to provide the online casino with several documents including:

  • Identity: Passport, ID card or a driver’s license
  • Address: A utility bill or credit or debit card statement no older than three months or a council tax statement

In some instances, you may also be asked to verify your source of funds. This usually involves you sending in documents such as your proof of earnings (A payslip, evidence of dividends or pension), bank or savings statements, or proof of a payment or reward from another casino.

You’ll need to send the documents over to accounts@21casino.com. Once the documents and your account has been verified, you’ll be allowed to deposit and withdraw at the online casino with no problem.

Important: As of 14th April 2020, UK Casinos and Bookmakers no longer accept credit card deposits as per new regulation issued by the UK Gambling Commission.

Customer Support

21 Casino pledges to provide excellent customer support to its players. So, if you happen to run into a problem when playing or have a question, you can contact the support team by either emailing them on support@21casino.com or by using the 21 Casino live chat service. The 21 Casino customer support team is available 24 hours a day, seven days a week which means they’re always ready to help you out.

Live Chat: Our Experience

When we launched the 21 Casino live chat service, we were instantly greeted by a support agent. The agents answered all of our questions and were quick with their replies, but we found that they were vague with answers and always attempted to re-direct us to different pages on the website without fully answering our questions. That was disappointing. However, the agents were incredibly friendly and welcoming, which was nice.

If you do run into a problem when playing at 21 Casino, we do suggest you use the live chat service. However, it’s important to remember that the agents may be vague with you or may re-direct you to the website.


One of the most appealing factors regarding 21 Casino is that it’s mobile-friendly. While the site doesn’t have a dedicated mobile app, it does allow users to play in-browser. This can be done by launching your smartphone app, loading up the online casino and then either registering or logging in.

Once you’ve done this, you can play your favourite games, contact the support team, claim bonuses and promotions, and deposit and withdraw money. However, it’s worth noting that older games developed with Flash technology may be incompatible with most smartphone devices, which means you cannot play them. This can be frustrating if it’s a game you enjoy, but the collection of games available at 21 Casino is so vast we’re sure you’ll find something else you enjoy.

Sister Sites

As mentioned, 21 Casino is owned by White Hat Gaming Limited, a firm which also owns several other gambling websites. This means that the 21 Casino sister sites are 21 Prive, Diamond 7 Casino, G’Day Casino, Hello Casino, Mainstage Bingo, Casilando, Gold Spins, Dream Vegas, Casimba, Temple Nile, Jonny Jackpot, Fruity Casa, Miami Dice, Playgrand Casino, Slot PLanet, Spinland, Spinrider, Spinstation and many more.

If you do enjoy playing here, we suggest you try out 21 Casino sister sites Miami Dice, Temple Nile, the Grand Ivy, Casimba, Fruity Casa and Dream Vegas, all of which offer a great selection of games as well as numerous promotions and bonuses.

It’s worth pointing out that some people confuse 21 Casino by White Hat Gaming Limited with 21.co.uk, an online owned by LeoVegas Gaming. While both sites offer games and promotions, they generally feature different bonuses as well as a collection of various games.

21 Casino is a great online casino. The site offers a huge collection of games and several generous bonuses, all of which help make the casino more exciting. Payouts at 21 Casino are fast and the site accepts most major payment options, which allows players to use their preferred payment option.

However, we’re disappointed with the lack of table and live casino games, particularly compared to the expansive slot collection. In addition, the lack of a dedicated 21 Casino mobile app can also be a problem for some users. Despite this, the site is great and well worth joining, so if you’ve read our 21 Casino review and believe you may enjoy the site, why not try it out yourself?
