21Prive sister sites

Our original 21Prive sister-site reviews

Hello Casino and Slotnite are active domain entries; 21 Casino, Miami Dice, SpinYoo, Playzee and Casimba are white labels. The profiles below compare their themes and game selections. Their older bonus descriptions are historical and should not replace the present offer terms.

21 Casino is a close match for 21Prive – and we’re not just saying that because both casinos have the number 21 in their names. White Hat Limited is an operator that has an affinity for the classics, which means there are a fair few 21Prive sister sites that lead with traditional casino games more than slots. That doesn’t mean there aren’t great slots to play at 21 Casino – there are actually plenty of them – but a spinning roulette wheel is the first thing you’ll see when you arrive on its homepage. You’ll also see details of the latest 21 Casino welcome promotion, which is a matched deposit of 121% up to £100 on first deposits only. Given that wagering requirements are OK at 35%, it’s a reasonable promotion and a nice start to life at the casino. It’s light on long-term rewards, though.

There are a lot of 100s at Hello Casino. New players can claim a one hundred per cent matched deposit promotion up to a maximum limit of £100, and the offer comes with one hundred bonus spins. That’s a pretty warm welcome, but you’d expect nothing else from an iGaming site called “Hello Casino” – if it couldn’t get its welcome promotion right, it wouldn’t be worthy of the name. This is one of the plainer 21Prive sister sites in terms of its appearance, but there’s plenty of range and depth to its games portfolio. You’ll find options for great slots, plenty of live dealer action, and even a selection of Slingo games. Hello Casino also has access to the White Hat Gaming Limited loyalty reward scheme, which sometimes goes missing at the smaller sites on the operator’s platform. All in all, it’s a solid site.

You’ll be more likely to recognise the theme and branding of Slotnite if you’re up to date with what’s popular in the world of video gaming. The biggest game in the world for the past few years has been Fortnite, which is a battle royal-style shooter. It’s especially popular for young players, which means there are questions to be asked about whether it’s a suitable theme for a casino, but we’re not here to pass judgement on that. It’s more important to us that this is one of the biggest 21Prive sister sites when it comes to the number of casino games it has to offer. It might focus on slots to the almost total exclusion of everything else, but it has more than two thousand slots to choose from. That means all your favourites are here, but so are plenty of hidden gems which you may never have come across before.

If you’re above a certain age – let’s say forty – you’re more likely to recognise the branding of Miami Dice than you are with Slotnite. It clearly takes its inspiration from the classic 1980s police drama “Miami Vice,” which Hollywood movie producers unsuccessfully tried to bring back as a film franchise a few years ago. Even the pink and blue colour scheme of Miami Dice is borrowed from the television show. The casino’s cartoonish style is easy on the eye, and the welcome promotion is reasonable, even if it’s true to say that you’ll get more free spins with your welcome promotion at some of the other 21Prive sister sites. You can broadly draw comparisons between the collection of games here and the collection of games at 21 Casino, which is to say that there’s plenty of depth and a good variety of categories.

Spinyoo is one of the newer 21Prive sister sites and is an attempt by White Hat Gaming Limited to create a “smart” casino. The site pays attention to the games you play and the way you usually bet on them. As it gets to know you better, it starts to make personalised recommendations to you from its considerable collection of roughly one thousand casino games. That’s only half of the range you’ll find at Slotnite, but it’s still a big enough number to ensure that players at Spinyoo are unlikely to have to worry about getting bored. When it comes to design, Spinyoo is a very modern-looking casino site which somehow manages to get away with using a grey background by using neon colours to highlight the information that it wants you to look at. It’s also flexible; there are separate welcome promotions for those who want to play slots and those who want to play table games.

Playzee is one of the best-known 21Prive sister sites. It might even be the best-known of them all, thanks to a sustained marketing campaign that’s been going on for some time. Whether you’ve heard of Playzee in the past or not, you’ll surely be impressed by its welcome promotion. New players can claim up to £300 as a matched deposit, get one hundred free spins into the bargain, and also receive five hundred loyalty points the moment they sign up for the site. Our earlier review recorded wagering requirements of x35, described then as in line with UK averages. As of our July 2026 check, 21Prive’s live homepage promotes up to 500 wager-free spins across a player’s first 14 days, with winnings kept as real cash, so the position has changed substantially in players’ favour. The “mad professor” theme is as entertaining as it is cheesy and provides the site with an excuse to use puns – free spins, for example, are called “zee spins,” and players are cordially invited to “enjoy zee games.”

Casimba is an unusual casino in that it owes all of its branding to an intellectual property that it doesn’t own. You don’t need to be a Disney aficionado to know that Simba is the main character in “The Lion King.” You’ll see the face of a lion in the middle of the casino chip in the Casimba logo, so there’s an obvious attempt to make a connection, even though Disney would surely never approve of such a thing. We assume that the connection isn’t strong enough to arouse the ire of Disney’s lawyers. That aside, Casimba is basic compared to most of the other 21Prive sister sites. Perhaps the most notable thing about its design is that you can flip between light mode and dark mode depending on your preferences, which is something more casinos should think about implementing.

21Prive’s earlier design and game selection

The earlier 21Prive product had a loyalty scheme, a mixture of prominent classics and new releases, and a fairly plain design. Those features explain the assessment below. Its current points-based welcome offer differs from the old fixed bonus, and the current cashier terms should determine minimum withdrawals, documents and payment routes.

Other Promotions (historical)

You’ll find the same loyalty reward scheme here as you will at many of the 21Prive sister sites. Unfortunately, it isn’t great. Players get 500 loyalty points when they first join the casino, which is a great start, but from there, they accrue at a rate of just 2 per £10 spent on slots. The accrual rate is even slower than that if you’re not playing slots; 0.25 per £10 on roulette and 0.5 per £10 on blackjack, for example. The conversion rate of loyalty points into bonus cash is £5 per thousand. That means a £500 spend on slots is required to get just £5 in bonus cash. Small deposit boosts are also available every Sunday at the casino.

Top Games at 21Prive (historical)

Casinos have a habit of attaching their top games to their welcome promotions. As such, we can say that the top games at 21Prive are Starburst and Gonzo’s Quest. Both are NetEnt slots, and both are thought of as bonafide classics. Gonzo’s Quest is one of the most popular adventure-themed casino games of all time, and Starburst is the most popular slots game in any category, ever. We suspect you’re more than familiar with both. The slots that feature on the homepage of 21Prive are a mixture of new releases and classics. You’ll find titles like Big Bass Splash there, but you’ll also find games that are hot off the press.

Final Thoughts on 21Prive (historical)

21Prive is starting to look old, which is understandable when you consider that it’s been online since 2014. A redesign to mark ten years in the business would be a shrewd idea on White Hat Gaming Limited’s part. The welcome offer at the casino is strong, and there are around one thousand games, so there’s no reason why players can’t have fun at the site, even if it’s dated.
