21 Casino Review
21’s a number gamblers love, so this 2015-created casino site from seasoned industry operators White Hat Gaming Ltd has a head start into the affection of players.
21 means blackjack to most of us – the hand that pays the best in the world’s favourite casino card game. And you can enjoy the hell out of blackjack at 21 Casino, including lots of live versions. You can do a lot more than that too at this nicely designed and slick looking site.
21 Casino has hundreds and hundreds of games, taking in slots and casino simulators as well as those live casino tables.
White Hat Gaming are based in Malta, along with the majority of Europe’s online casino industry. The company operates as a turnkey and white label provider. Turnkey is a business term that means a business is sold ready to go: turn the key in the lock and open up! And turnkey casinos are fully-fledged casino sites that are developed and set-up by people like White Hat gaming and then sold for others to run. The White Label model is very similar. A company with the facilities – hosting, licensing, customer support – runs sites as franchises, with the end-operators putting their own branding on the site.
Both models are really popular in the industry. They have pros and cons for you, the customer, which we’ll cover in this review, but you can trust White Hat to live up to their name and provide a safe and legal service.
And beyond that, should you start counting to 21 at this site?
Let’s dive in and see.
21 Casino Pros & Cons
Casino sites are complex operations and judging them takes time, but let’s have a quick look at the headlines from 21 Casino.
Pros:
A Licensed and Legal Site
Let’s get the most important thing out of the way first. White Hat are licensed to provide a number of remote gambling services to UK consumers by the UK Gambling Commission. In fact, they’re also licensed by the authorities in Malta.
Both these authorities are considered good quality regulators. To more important for you, though, is the UK Gambling Commission licence.
We’ve checked it, and it’s up to date, and there are no sanctions against the company, who are confirmed as the operators of a number of sites in their own right – including 21 Prive, Diamond 7 Casino, and Gday Casino – and of white label site. The white labels include this one, 666 Casino, Miami Dice, Reel Island and many more.
The Malta licence is for the company.
Together, along with industry body memberships and the good quality safe gambling links on the front of the site it’s obvious that 21 Casino is a legitimate site that you can use safely.
A Big Selection of Games
We count 112 game providers at 21 Casino. From 1×2 Gaming to Yoloplay that’s a comprehensive alphabet of the industry, from big names like Red Tiger to smaller developers like Slide City.
These titles – which we’ll cover in full later – take in slots, jackpot slots, table games, live casino games, and other titles like virtual sports and scratch cards too.
The games are well arranged and easy to find – that providers list is there on the site to help you find your favourite makes – with a good search function and good site design.
Live, live, live!
Live casinos is what everyone seems to want from their casino sites these days.
We found a relatively small but good selection of live games from the best providers at 21 Casino.
The giants of the scene are NetEnt and Evolution Gaming, and 21 Casino has their titles, including all your casino favourites, like roulette and blackjack, but there are also game show games, virtual sports studios and more to check out.
Transparency
Back to the technical stuff again, but 21 Casino do a great job on telling its customers what’s going on with the site. As it’s our job to find out about a casino site we love sites that make it easy to do so.
So we love the good quality and easy-to-find information at 21 Casino and you should too, because things like privacy policies, and how to contact the help team are important and you need to know how to find them too.
Cons:
Nobody’s perfect, as they say! So here are some down sides at 21 Casino
Standardized
Are you bored of sites that look the same and offer very similar levels of service and performance? 21 Casino does a lot of things very well indeed, but like all white label casino sites it comes from a standardized template. This doesn’t affect quality in a lot of ways, but if you want to see something different or if novelty is a big thing to you then you may find things a little stale here.
Payment Options
Payment options change over time, and they are always worth checking before you sign up. A casino can have a huge game library and a slick design, but if your preferred deposit or withdrawal method is missing, that gets annoying very quickly.
There are usually several mainstream payment options at White Hat casino sites, but do not rely on an old review for this bit. Check the cashier page before you deposit, especially if you want to use a specific method such as PayPal, Skrill, Neteller, Trustly, or bank transfer.
Where are the offers?
The current welcome offer is easy enough to understand: 70 bonus spins on Book of Dead after your first deposit. That is cleaner than the old bonus-heavy offers we used to see in the UK market, and at least it does not look like it was designed by someone with a degree in complex astrophysics.
But where’s the rest of the glitz and glamour? Offers and bonuses have a downside, but it’s still nice to be offered a choice, and 21 Casino doesn’t appear to have a huge amount going on beyond the welcome offer at the moment.
21 Casino Games and Software
The site is run on White Hat’s own software, with games from over 100 developers.
Let’s go through some of them.
21 Casino Slots
Slots are the bread and butter of the online casino industry, and as you’d expect they are the main part of the offering at 21 Casino.
They arrange their games in a number of ways to preview them, including by provider, including:
4ThePlayer, Alchemy Gaming, Bally, Barcrest, Cayetano, Core Gaming, ELK Studios, Fantasma Games, Green Jade, IGT, Iron Dog, Just for the Win, Kalamba, Live 5 Gaming Mutual, Netent, NYX, Old Skool Studios, PG Soft, Play’n GO, Red 7, Slingo, Snowborn Games, Thunderkick, Wazdan and Yoloplay.
At the front of the site are:
New Games at 21 Casino
These included on our visit: Yucutan’s Mystery, Neon Pyramid, Wild Gods Egypt, Classic Fruits, 1,2,3 Boom! Gladius KO, Stamp Wild, Dragon Hatch, and Raging Rhino Ultra Mega Drop.
Popular Games at 21 Casino
Slots are mixed in with other games here, but we’ll pick out the slots among the most popular games, and you’ll see some old favourites here:
Legacy of Dead, Starburst, Money Train 2, Jammin’ Jars, Lil Devil, Rich Wilde and the Book of Dead, Danger High Voltage, Gonzo’s Quest Megaways, Eye of Horus, and Immortal Romance.
More Slots at 21 Casino
By browsing all of the titles we can see hundreds more titles, including:
The Goonies, Diamond Mine Megaways, Rise of Olympus, Dead or Alive, Rainbow Riches Pick n Mix, Primal Megaways, Dead or Alive II, Rainbow Cash Pots, and Fruit Warp.
Jackpot Games
You want big prizes? Head to the jackpots list to check out some progressives, including these industry leading millionaire makers!
Reel King Mega, Rainbow Jackpots, Mega Moolah, Divine Fortune, Wish Upon a Leprechaun, Super Diamond Deluxe, Dragon’s Luck Power Reels, Mega Joker, Devil’s Number and Patrick’s Jackpot.
Table Games
Casino games come in two flavours. The games we’re listing here are called Table Games at 21 Casino. These games are computer simulations of games, not live games, which we’ll cover later.
We found 40 games in total, taking in all the classics, and poker.
Roulette
Everyone loves roulette – including casinos, who can make a nice profit from this classic game! At 21 Casino we found nine variants, including:
European Roulette, Roulette Nouveau, Double Ball Roulette, 3D European Roulette, Roulette Advance, European Roulette Gold Series, European Roulette, French Roulette, and American Roulette.
Blackjack
Blackjack has a few variants, and there are lots of branded titles and rule options that include different side bets and different player options. Please study the game – or play on demo mode – before you start to throw your chips on the table.
At 21 Casino we found:
Blackjack, Blackjack Pro Monte Carlo Pro MultiHand, Blackjack Pro Monte Carlo Single Hand, Blackjack 21 + 3, Blackjack Lucky Ladies, Blackjack Lucky Lucky, Buster Blackjack, 3D Blackjack, Atlantic City Blackjack Gold Series, 6 to 1 Blackjack, European Blackjack, and Blackjack Perfect Pairs.
Poker
Poker can be played as a live game, as a simulator, and in a slot variant called video poker. Here we’re looking at table game simulators, which deliver dealer games.
At 21 Casino you can play:
Casino Hold’em, Texas Hold’em, 3 hand, Casino Hold’em, All Aces, Poker, Mississippi Stud, Pai Gow Poker, DJ Wild Stud Poker, Jacks or Better, Let it Ride, and Texas Hedge ‘Em.
Other table games at 21 Casino
Also available at 21 Casino are baccarat, dice games, and Casino War.
Bonuses at 21 Casino
Every site will offer you a number of promotions. Typically these will include a welcome offer – always the biggest and most eye-catching – and, often, a loyalty programme.
Welcome Bonus at 21 Casino
Talking of eye-catching, the current 21 Casino welcome offer is much simpler than the old 121% deposit-match offer that previously appeared on this page.
At the time of this update, new players can get 70 Book of Dead bonus spins on their first deposit. The minimum first deposit is £15.
That is not the biggest headline offer in the world, but smaller and clearer is often better than a giant bonus that turns into a maths exam after you open the terms.
Here’s what the current welcome offer says:
- New players only.
- 70 bonus spins on Book of Dead.
- Minimum first deposit: £15.
- Bonus spins must be used within 10 days.
- Winnings from bonus spins are added as bonus funds.
- Bonus funds have a 10x wagering requirement before they can be turned into cash funds.
- Only bonus funds count towards wagering contribution.
- Affordability checks apply.
So yes, it is a straightforward offer, but it still has terms. Did you really think the casino was going to hand out bonus spins with no strings attached? Of course not.
Wagering Requirements
A wagering requirement is the amount you need to play through before bonus funds or bonus-linked winnings can become withdrawable cash.
For the current 21 Casino welcome offer, winnings from the bonus spins are added as bonus funds, and those bonus funds have a 10x wagering requirement. In plain English, if your bonus spins produce £10 in bonus funds, you would need to wager £100 with those bonus funds before they could become cash funds.
That is much cleaner than the old 35x-style bonus terms that used to sit on this page, but it is still not free money. You need to check the game, the time limit, the wagering rule, and the bonus-fund restrictions before claiming.
We are not big fans of the bonus scene in the UK casino market. The purpose of a bonus is obvious – it is to get the player in through the door, but also to encourage them to deposit and play. Keep this in mind. The best way to use a bonus is as a quick guide to the site. Forget about the idea of getting rich from it, and be ready to walk away if the terms do not suit you.
Other Promotions
Promotions come and go and are often tied to calendar events, game releases, and current events. They change regularly, and you should check in as you sign up to see what’s on offer and if you like it.
Tournaments
We did not find a strong tournament offer to shout about at 21 Casino at the time of this update.
Daily Promotions
We also did not find a busy daily promotions page. That is not necessarily a disaster – some players are better off without ten flashing bonus buttons trying to separate them from their debit card – but it does mean the current bonus setup feels quite limited.
21 Casino Loyalty Schemes and VIP
No modern casino doesn’t have some kind of loyalty angle. Most are triggered automatically as soon as you join the site. It’s another feature that regulators are believed not to be keen on, and – as their concerns are related to the extent to which loyalty schemes, and particularly VIP schemes could encourage dangerous gambling behaviours – it is something that you need to be aware of too.
21 Casino has previously promoted a loyalty scheme called Royal Loyalty, which was simple enough to understand: play, earn loyalty points, and redeem points as bonus cash.
That kind of simplicity is good, but the same warning applies. Loyalty schemes are not gifts from the heavens. They are built to encourage more play, and if that’s not a good thing for you then you need to make the right decisions for you – not the casino site.
If you are interested in the loyalty scheme, check the current terms on 21 Casino before relying on old point rates, redemption values, wagering rules, or expiry times.
21 Casino Live
Live casinos are taking players back to the future. The very latest in web tech is used to deliver what you could have got by walking into a casino in the past. Games are played at a remote location and a weblink handles the interface between the player and the dealer or croupier.
Be aware that live games are often slightly more expensive to play, because of the cost of staffing all those tables, and you can very rarely try out the games for free – so make sure you know the rules properly.
Also be aware of the use of sexualised imagery and attractive staff to encourage you to play and spend more. Make decisions that are good for your health and your bank balance, not based on a perceived relationship with casino staff. Always treat casino staff with the utmost respect too.
At 21 Casino we found a quite small but high quality selection of games.
Not all casino tables are available to all players at all times, so you need to be aware of that.
We found:
Live Roulette at 21 Casino including Evolution Gaming Roulette Live, NetEnt Classic Roulette, and Auto Roulette.
Live Blackjack at 21 Casino included Evolution Gaming Blackjack, and NetEnt Blackjack Live.
You can also play Baccarat Live, various poker titles (including Texas Hold’Em, Three Card Poker, and Caribbean Stud Poker.
Other titles included Mega Ball, Deal of no Deal, Dream Catcher, Dragon Tiger, Sic Bo, and Football Studio.
21 Mobile Casino and App
Mobile access provides access to the majority of games and services on the site via a mobile adapted website. There is no app to download.
Banking
Banking makes the casino world go around.
At 21 Casino there’s a good selection of the latest payment methods with which to open your account, fund your play, and receive winnings.
They include:
- Visa debit cards,
- MasterCard debit cards,
- Maestro debit cards,
- Trustly,
- Paysafecard,
- Skrill,
- Neteller,
- PayPal,
- Bank Wire.
Customer Support
Customer service is just about the most important thing at a casino site – beyond the legality. Hopefully these are services that you’ll never need to use, but every player should make sure that they know what customer support is available to them and how they can access it.
At 21 Casino you can use a live chat button to open a chat window that is open 24/7. Or you can email support@21casino.com.
The Final Verdict
Casino 21 delivers a lot of good things without exactly setting the world on fire. In casino terms, it is a great mid-table premier league club but it’s not one of the big guys who you should expect to see in the Champions League every year.
The things it does deliver include:
Nice design that make a site that’s easy to use and a pleasure to look at.
Lots and lots of good games, that are well arranged and easy to find.
It also scores pretty well for the quality of information that is available around the site.
It’s great to see a simple, straightforward loyalty scheme that isn’t weighed down with bells and whistles and stupid jargon!
The current welcome offer is modest rather than spectacular: 70 Book of Dead bonus spins on your first deposit, with 10x wagering on any bonus funds created from those spins. That is cleaner than the old high-wagering bonus world, but it is still a bonus, and bonuses always need reading carefully.
Everything at 21 Casino can still give you a solid casino experience if you like the White Hat style of site.
Our only real concern – beyond that strange welcome offer – is that what 21 Casino does is almost exactly the same as what a whole lot of other sites do. And because it is a white label site that means that in some cases it is exactly the same service and offer.
How should you rate this site? The best thing for players faced with a lot of quite similar sites is to shop around, but to be aware of the dangers of chasing bonuses. There’s enough at 21 Casino to make it a perfectly good site for the long-term, especially if you like simple bonus-spin offers and a big game library, but if you already have a good favourite site then you might not want to switch. Take a look and judge for yourself.
