21 Casino Welcome Bonuses – 4/5

We’ll begin our 21 Casino review with details of their fabulous welcome bonus. New customers can claim a welcome offer of 121% up to £300 when they sign up. There is no 21 Casino promo code required, just a successful registration and a qualifying deposit amount.

Welcome Offer

Let’s look a little closer at how you can qualify for your 21 Casino welcome bonus. Sign up and make a deposit. You will then receive 121% of your deposit as a bonus, up to a maximum of £300.

To make the most of the bonus, there are a number of 21 Casino bonus terms and conditions to be aware of. The minimum deposit for this 21 Casino Casino Bonus is £10. To turn your bonus into cash, a 35x wagering requirement applies. When using your bonus funds, a maximum stake of £5 applies.

There are different game weightings which will contribute to these wagering requirements. For example, some slots contribute 100%, though for some slots this is reduced to 20%. There are also a number of slots that don’t contribute any percentage to the wagering requirements. Table games, video poker and scratchcards all contribute different amounts.

For the latest game weightings, check the 21 Casino bonus terms and conditions on the site.

In addition, you have 30 days in which to use your bonus. Any bonus funds remaining after this time will be removed from your account.

Our overall 21 Casino opinion on their welcome bonus? It’s an attractive offer on the surface. The wagering requirements are slightly high, though, and the game weightings are reasonably complicated. For instance, some slots contribute 100%, others contribute nothing.

The amount in bonus funds you could receive, though, is higher than most that we’ve seen on the market this year. This could be a good offer, as long as you understand and adhere to the terms and conditions stated.

You can join up and claim this offer using any of the links found in this 21 Casino review.

Let’s continue our 21 Casino review by exploring all of your betting options.

21 Casino Other Promos – 3/5

There can’t be a complete 21 Casino review without examining what’s available for existing customers. As we’ve seen, our 21 Casino opinion surrounding the available welcome bonus is a good one.

It is, though, just as important that an operator offers a range of promotions for existing customers too.

One such offer that could be available is their Pit Stop Spins promotion. Existing customers can take advantage of 21 Casino free slots, once a qualifying deposit has been made.

Another possible promotion is the Wild Reload bonus. When available, this offer can give you bonus funds on top of a qualifying deposit.

There is also a Loyalty program available here. Existing customers can earn loyalty points with every stake they place. Once enough points have been earned, they can then be swapped for bonus funds.

Other offers, such as a 21 Casino no deposit bonus or 21 Casino free bingo offers, can also be an option on occasion.

As with any 21 Casino casino bonus, always ensure you read all terms and conditions attached.

When new offers become available, we’ll let you know in our 21 Casino review.

21 Casino Website – 4/5

Any online site needs to have an easy-to-use, interactive interface. We’ll continue our 21 Casino review by examining how this operator’s platform works.

It’s extremely easy to navigate around the site. Once you’ve completed your 21 Casino login, the site is open to you. Finding the game or slot you want is a simple task. Use the tabs across the top of the screen to find your choice.

No additional software is required to play any of the games here. We recommend, though, that you have the latest updates installed on your desktop for a seamless betting experience.

Mobile play is also an option. There is no downloadable 21 Casino app, but you can add the operator to your home screen directly from the website.

21 Casino mobile provides an equally seamless experience. You can access your full account via your mobile browser with ease. All that is required is your 21 Casino sign in.

21 Casino Payment Options – 3/5

For this 21 Casino review, we examined which payment options were available. There is a range of payment methods available here. Minimum and maximum deposit and withdrawal amounts can vary, depending on which method you’re using.

For UK customers, the following methods are available.

  • Visa debit
  • Mastercard debit
  • Maestro debit
  • Trustly
  • paysafecard
  • Skrill
  • Neteller
  • PayPal
  • Bank Wire

Customer Service – 4/5

No 21 Casino review would be complete without analysing their customer support options. Often an ignored aspect of an online site, a good customer service facility means fewer worries for the customer.

We’re pleased to find that, in our 21 Casino opinion, customer service here is certainly a plus point. This operator offers a 24/7 live chat service. If you prefer a different way to contact the team, email is an option for you.

We would have liked to have seen a dedicated help or frequently asked questions function here. However, the 24 hours a day live chat service should help you deal with any queries or questions you have quickly.

21 Casino Review – Our Verdict

Our 21 Casino opinion is an excellent one. There is much to get excited about with this operator. The range of 21 Casino games, and in particular slots, is hard to match, and the interface allows for seamless gameplay.

There are areas which we’ve discovered in our 21 Casino review we’d like to see improved slightly. A Help function or FAQ tab would be a nice addition to the site. Other new customer offers focused on a variety of games would also be good to see.

It’s also our 21 Casino opinion that the game weightings in the offer we’ve discussed can be slightly confusing.

As it is, though, our 21 Casino opinion remains a good one. There are a few online casinos which can match this operator for the size of welcome bonus and number of slots and games.

We’ll end our 21 Casino review by reminding you of that all-important welcome bonus. New eligible customers can claim a bonus on their first deposit.
