Onyx Slots Sister Sites 2024

Grace Media (Gibraltar) Limited is a casino network company that’s been through a lot of changes in recent years, including moving its entire head office from Manchester to Gibraltar – presumably to take advantage of the friendlier tax conditions on “The Rock.” It’s also closed down a whole load of former Onyx Slots sister sites and introduced new ones like Mango Spins, Jackpot Molly and Vegas Kings Casino. Here, we’ll be taking a closer look at those sites and also undertaking the internet’s most detailed review of Onyx Slots.

Mango Spins

Mango Spins logo

Fruits have been the inspiration for online casinos for as long as online casinos have existed, and for quite a long time before that, too. That’s why slot machines used to be called “fruit machines” or simply “fruities.” When we talk about those classic fruit connections, though, we’re talking about lemons, cherries and plums rather than the more exotic twist you’ll find at Mango Spins, which is one of the newer members of the Onyx Slots sister sites family. As with most of the more recent additions to the platform, the design of Mango Spins is based on a fairly basic template. It looks fine – it’s clean and modern enough – but the sameness of the design means that the casinos that use it often look like much of a muchness. Still, there’s a solid selection of slots and promotions at Mango Spins, and for most players, that’s the point of a casino site.

Vegas Kings Casino

Vegas Kings Casino

We’ve been reviewing and comparing online casinos for a very long time now, so we’ve seen what feels like one thousand takes on the Las Vegas theme. If we’re being honest, Vegas Kings Casino doesn’t rank up there with the best of them. Almost zero effort has been put into the theme, with even the logo feeling uninspired. If you’re going to use a Vegas theme you need to put some glitz and glamour into it, else you might as well not bother. Vegas Kings Casino uses the same design as Mango Spins and so many of the other Onyx Slots sister sites, which means it fades into the background a little when you compare it to the very best casinos on the network. Again, though, it’s redeemed by the quality of its bonuses and the games that it offers, which mirror those we just saw at Mango Spins.

Hot Streak Casino

Hot Streak Casino logo

Hot Streak Casino looks just like the other two Onyx Slots sister sites we’ve looked at so far. You can see that just by looking at the screenshot below. However, Hot Streak is one of Grace Media’s most popular online casinos, and we’re not sure why. It joined the platform in 2023 and started doing big numbers almost immediately. That’s despite the fact that it doesn’t even seem to be sure about what it wants to be called. The logo, which you can see above, very clearly names the casino as Hot Streak Slots. The site’s web address, on the other hand, is hotstreakcasino.com. We’ve gone with the latter for our purposes because that’s how the casino’s name appears on the operator’s UK Gambling Commission record, but it’s a bit confusing. As for the promotions, games and other material factors – they’re all identical yet again.

Jackpot Molly

Jackpot Molly

Who’s Molly, and what’s she done with our jackpots? Those are both good questions, but we’re afraid we don’t have answers for either of them. We don’t know why this member of the Onyx Slots sister sites family is called “Jackpot Molly.” We do know, however, that it went live during the second half of 2023, so it’s comparable to Onyx Slots in terms of both its age and the features that it offers. Then again, we’ve said almost the same thing about all of the other Grace Media casinos we’ve looked at on this list so far. While an Irish theme based on the name “Molly” might have brought Jackpot Molly to life a little bit, it’s still a perfectly good casino site with just as much to offer as most of the other online casinos in the Grace Media family. It just isn’t anything special.

Planet Rock Casino

Planet Rock Casino logo

Most people will feel that Planet Rock Casino is the biggest and best of the Onyx Slots sister sites, and there are good reasons to hold that opinion. One is that it’s the only casino on this operator’s entire platform to have a big-name branding deal, being the official iGaming presence of Planet Rock Radio. Another is that, unusually for the casinos on this network, it has a unique look and a particular focus. Unsurprisingly, that focus is rock music. The branded jukebox slots of some of the biggest bands and artists in the history of rock music are plastered all over the casino’s homepage, including Guns n’ Roses, Jimi Hendrix and Ozzy Osbourne. If you’re someone who loves casino games but also loves your music loud, it’s hard to imagine where you’ll find an iGaming site better suited to your interests.

Onyx Slots Review 2024

According to the dictionary, onyx is a semi-precious layered stone that can come in a variety of colours but is always dark and is often entirely black. That probably explains why the background of Onyx Slots, which launched in 2024, is also dark. We suppose it’s like calling the casino Ruby Slots or Diamond Slots, but Onyx Slots is a more original choice, and we salute Grace Media for that – especially since so many of the company’s casinos are almost identical in so many ways. Originality is hard to come by on this platform, but let’s see if Onyx Slots has managed it.

Onyx Slots sister sites homepage

Onyx Slots Welcome Offers

There are up to one hundred bonus spins available for new players at Onyx Slots, and the good news is that there are no wagering requirements attached to the spins at all. If you win anything, you’ll be able to withdraw your winnings as real money immediately. The bonus requires a £10 bonus for twenty free spins on Zeus vs Hades: Gods of War, and can be claimed five times to bring up the full one hundred. Act quickly when you’ve made your deposit, though – the spins will expire in five days if they’re not used.

Ongoing Promotions

The sign-up offer we’ve described above is the only bonus that appears on the casino’s Promotions page. We weren’t initially worried about that on account of there also being a Rewards page, but clicking on that link brought us nothing but disappointment. The “rewards” Onyx Slots tells us about on the page are new games every week, special jackpot games, and cutting-edge player protection. These are all fine things, but they’re not what players have in mind when they navigate their way to a rewards page on a casino website.

Elsewhere on the same page, Onyx Spins promises players that loyalty to the casino is rewarded by matched bonuses, win boosts, cash prizes and bonus spins, but there’s no further information provided. Given that the casino was built from a template, we can only assume that this information was left in by mistake – no additional bonuses appear to exist.

What are the Pros and Cons of Onyx Slots?

Pros: This is a casino that gets to the point very quickly. From the moment you land on its homepage for the first time, you can see what the welcome bonus is and what the top slots and games are. You can also see that the welcome bonus comes without any wagering requirements, which is a nice treat for newcomers.

Cons: As a whole, the casino is just a little too basic. The lack of any ongoing promotions hurts it badly, and a tally of fewer than one thousand games means that the casino doesn’t keep pace with the best in the business. Being unable to provide instant or even same-day withdrawals goes against it on that count, too. It’s a perfectly solid casino, but it’s not one that’s likely to live long in the memory after you’ve played at it.

Top Games at Onyx Slots

The clue is in the name. Onyx Slots mostly focuses on slots, so the fact that it also has a live casino and a collection of instant win games is very much an afterthought. You’ll eventually find those categories if you go rooting through the side menus or scroll far enough down the homepage, but by that time, you’ll have seen dozens of the casino’s top slots. They’re grouped into categories to make them easier to find, and two of those categories are worthy of note. The first is “hot slots,” which is where you’ll find the slots that are the most popular with other players right here and now. They’ll change every time you visit the casino, but you can be fairly sure you’ll find Wolf Gold, Call of the Wild and at least one Big Bass Bonanza option here.

A little further down the homepage is the “Featured” section, where you’ll find the titles that Onyx Slots has chosen to highlight. They include Starburst and Fishin’ Frenzy, both of which are as safe as safe choices ever get. It’s interesting that the casino has opted to showcase Boat Bonanza in the same category, though, as it’s broadly seen as a lower-quality Big Bass Bonanza rip-off. Gold Cash: Big Spins is also in the Featured row, and is also a slots game we’re sure you’re already well aware of.

Withdrawal Processing and Support

Any UK-registered and verified debit card is fine for making withdrawals from Onyx Slots, but you’ll get faster results using Trustly or an e-wallet held with either PayPal or MuchBetter. If you request a debit card withdrawal on Monday, the earliest you’ll get it is the following day. However, in some circumstances, you might have to wait a full week until the following Monday. With Trustly or an e-wallet, on the other hand, your withdrawal should never take more than forty-eight hours. That’s the way to go if you have the option.

Customer Support and Licensing

There’s a live chat feature at Onyx Slots, but it’s run by a pretty basic bot. You’ll have to tell the bot to go away more than once before you’ll be connected to a real human, so that’s an annoyance. There’s a contact form you could use instead, but we have no idea how long it might be before someone at the casino picks the form up and gets back to you. Like all Grace Media (Gibraltar) Limited casinos, Onyx Slots is covered by UK Gambling Commission licence 57869, which is clean and free of fines or warnings. The same licence also covers the Onyx Slots sister sites.

Onyx Slots – The Verdict

Onyx Slots is a casino that you’re not going to get especially excited about unless you have a big win. It’s very hard to find any material differences between Onyx Slots and at least a dozen other Grace Media casinos, so if you’re a fan of the way this operator makes iGaming sites, there’s no reason why you won’t also like this one. It’s a little bland, though, and the lack of ongoing promotions or loyalty rewards might leave you feeling a little short-changed after a while.
