21 Casino sister sites 2025
GDay Casino
It would be a huge surprise if we were to tell you that GDay Casino isn’t an Australian-themed casino. Don’t brace yourself for surprises because we’re not about to do that. The theme of this casino is as Australian as you’ll ever see. It has fun with the idea, and it provides a colourful environment for casino players to enjoy. If the “greeting theme” is even a thing, GDay Casino is one of to greeting-themed casinos among the 21 Casino sister sites. The other is Hello Casino, which tends to enjoy a higher profile than GDay Casino does. There isn’t much to pick between them in terms of overall quality, though, and it has access to modern “game show” style games like Football Studio as well as the expected array of slots and casino classics. The welcome package isn’t enormous, but even the average welcome offers on the White Hat Gaming platform are better than the best you’ll find on some other platforms.
Spin Rider
If we were handing out awards for the best-looking casinos among the 21 Casino sister sites, almost all of them would be lining up behind Spin Rider. It’s mean, moody, slick, and very impressive. We suspect that the theme of the site owes a little something to the popularity of the “Fast and Furious” movie franchise, but it makes for spectacular visuals. There’s substance to go with the style of Spin Rider, too. Its welcome promotion of up to £300 in matched deposit bonus cash is more than generous, and the terms that go with it are fair and balanced. If we have one complaint about Spin Rider, though, it’s that all the animated and video content on the homepage chews bandwidth for fun. This probably isn’t a casino you’re going to want to visit if you’re on the move; wait until you have a Wifi connection. Alternatively, there’s a dedicated Spin Rider app you can download. That’s not something that all of the 21 Casino sister sites can boast of having.
Slotnite
The very fact that Slotnite exists as an online casino is interesting. We all know how gambling authorities feel about iGaming companies marketing to children. We aren’t accusing White Hat Gaming Limited of doing so, but Slotnite is, very obviously, based on the Fortnite video game. The Slotnite logo and the Fortnite logo are virtually identical, as is the colour scheme. Even the Slotnite loyalty bonus is awarded in “XP points” rather than loyalty points, which is a convention we associate with video games. Why are we telling you all this? Because, for those who don’t know already, most of the people who play Fortnite are too young to gamble. We can see why the theme has been chosen because it was always bound to be popular, but it feels like a risky one. Nevertheless, Slotnite has risen through the ranks quickly to become one of the most popular 21 Casino sister sites, so who are we to argue with the logic behind the design?
Barz Casino
We’ve just said that Slotnite is an attempt to take advantage of youth culture by taking something that young people will be familiar with and turning it into a theme for an iGaming site. Barz Casino could easily have become the same thing. Rap music (and rappers) use the term “barz” to describe particularly impressive or effective verses. Off the top of our heads, we can’t think of a casino with a rap theme. Barz Casino could have found a gap in the market but chose not to do so. Rather than having a rap music theme, this is one of the most basic and plain of all the 21 Casino sister sites. It has no theme at all. That’s a statement of fact, but don’t get it confused for us saying that Barz Casino is boring. It doesn’t blow us away with its looks, but there’s plenty of scope for fun to be had with its welcome promotion, even if the wagering requirement is a touch higher than you’ll find at most 21 Casino sister sites.
Diamond 7 Casino
Diamond 7 Casino may not have the modern aesthetics of other casinos such as Slotnite, Playzee, or Spin Rider, but this is to be expected, given that it has been in operation for almost a decade. It is one of the oldest 21 Casino sister sites and is designed for players who prefer traditional games rather than flashy gameplay or big bonuses. However, this doesn’t mean that Diamond 7 Casino has nothing to offer modern players. While it caters to fans of classic genres, it also uses player data to make recommendations for new games. By keeping track of the slots and games you play and how you play them, the casino can suggest new games that you may not have come across otherwise. You are free to take or leave these recommendations, but it can be a great way to discover new games that suit your interests. It’s not going to win any design awards, but nor is it going to disappoint anyone who’s hoping for a fun casino experience.
21Prive
Given the similarities between the names, it would be understandable if you thought that 21Prive and 21 Casino were dead ringers for each other. That isn’t the case. Like Diamond 7 Casino, 21Prive is one of the oldest of the 21 Casino sister sites. It doesn’t look quite as shabby as Diamond 7 Casino because its design was ahead of the time when it first launched, but time has since caught up with it. Put the retro appearance of 21Prive aside for a moment, though. Its welcome promotion is more than fair, and like 21 Casino, it’s an iGaming site that’s about the live casino experience just as much as it’s about slots and other games. There are issues here – the lack of information about withdrawal processing being the most glaring – but it’s by no means the worst of the White Hat Gaming Limited casinos. It’s a reasonably solid bet, and it can give you most of what you’re looking for so long as your tastes aren’t extravagant.
21 Casino Review 2025
21 Casino Sister Sites Welcome Bonuses
The “21” in “21 Casino” is a reference to blackjack and works as a shorthand notification that this casino primarily serves the classics. Yes, there are slots here, but a casino with a name like this one is always going to be more interested in roulette wheels and table games. It takes the “21” moniker and turns it into a gimmick, with a matched deposit welcome promotion of 121% available against the first deposit a new player makes at the casino. There are clauses, though; the wagering requirement is x35, which is fine by the standards of the UK average, and the maximum bet using bonus funds is £5. That might be an issue for a few players and makes clearing the wagering requirement a time-consuming activity.
Other Promotions
The simplicity and value of the welcome offer were the good news about promotions at 21 Casino. Now, here’s the bad news:- It’s the only promotion at the casino. Plenty of 21 Casino sister sites have small daily promotions. Even the ones that don’t tend to offer access to White Hat Gaming’s usual loyalty reward scheme. 21 Casino doesn’t do either of those things and is all the poorer because of it. We don’t know why it’s opted out of the loyalty scheme, but it will doubtless have a harder time retaining customers because of it.
Top Games at 21 Casino
The short answer is that the top game at 21 Casino is good old-fashioned roulette. A roulette wheel appears in the background of the banner that runs across the top of the casino’s homepage, and there are other roulette graphics elsewhere on the site. If you’re looking for slots, though, the top games are the ones that appear on the casino’s homepage. They’re led by Book of Dead by Play’n Go, which isn’t exactly a surprise. Hundreds of online casinos lead with either Starburst or Book of Dead, and the only surprise at 21 Casino is that Starburst isn’t listed on it at all. Its place is taken by Legacy of Dead, which is a near-identical sequel to Book of Dead, and probably doesn’t need to be listed so prominently on the homepage. The other slots you’ll see here are Big Bass Bonanza and Fishin’ Frenzy, both by Reel Kingdom, and both presented with the fishing theme that’s become wildly popular in recent years. If it’s Megaways you’re after, you can also access Bonanza with a single click from the homepage.
Customer Support and Licensing
The primary method of customer support offered at 21 Casino is live chat, which ought to be available at all times of day. If you’re struggling to get a response, your other option is to email support@21casino.com. All of the 21 Casino sister sites (plus 21 Casino itself) are listed on UK Gambling Commission licence 52894, which belongs to White Hat Gaming Limited. The operator was charged with failing to follow regulations regarding money laundering and customer care following a UKGC compliance review in January 2021 and opted to pay a settlement of £1.3m rather than allowing the matter to proceed further.
Withdrawal Speed and Support
21 Casino leaves players in the dark about withdrawals. The casino has neither a banking page nor an FAQ page, which are the two places you’ll find withdrawal information at most of the 21 Casino sister sites. There are well over a dozen payment provider logos in the footer of 21 Casino, but without confirmation of which of them work for withdrawals and how long each method may take to deliver funds, they’re as good as useless.
Final Thoughts on 21 Casino
21 Casino might be a little too retro for its own good. Visually, it looks like it ought to focus on table games and live casino games, but it doesn’t promote them as prominently on its homepage as it should do. It lacks any ongoing promotions once the welcome promotion has been used, and the lack of FAQ or customer information on the page is a concern. Better quality can be found elsewhere on White Hat Gaming’s platform.
