About Onyx Slots

Onyx Slots is the rock solid new Grace Media casino site launched in April 2024.  Operated by the same team as Slot Strike and Slotty Slots, we’re thrilled to be one of the first casino review sites to list the latest in a great run of brands.

Grace Media is having a renaissance in 2024; it will be on our shortlist for most improved casino platform of the year. From the varied games catalogue to the new and fairer welcome bonuses, Grace Media is pushing past some of its rivals in the casino white label space. Forget what you thought you knew about them and keep an open mind. As a brand spanking new release, Onyx Slots is a great place to start your Grace Media journey if you haven’t already.

Theme & User Experience

Onyx is a black and white mineral and that theme runs through the site’s design. Many historical artefacts and monuments, especially from ancient Greek and Minoan civilisations, were crafted from Onyx. We like that the brand stays true to this history. Images of Zeus and Hades are strewn across the homepage. In fact, the welcome bonus free spins are eligible on such a slot. It’s this kind of thematic integrity that can really elevate a casino for the player, making it a truly immersive experience.

Bonus & Promotions

As we mentioned, the free spins that are part of the welcome package are Greek themed, eligible on Pragmatic Play slot Zeus vs Hades: Gods of War. This unique package involves five deposits, after which you can receive 20 wager free spins each time.

We’ve liked the fair welcome offers from all of Onyx’s sister sites, especially Slotty Slots, but this just might be our favourite of them all. There’s a large tendency in the industry right now to jump on the Big Bass Bonanza bandwagon. Yes, it is the world’s most popular game (and available at Onyx slots) but there’s no need for every site to have the same welcome offer!

Games Available

Onyx Slots has an enviable selection of slot games and this is the main attraction of the site. Under the details tab, we have every game creator and developer listed. Spoiler alert: it’s not a short list!

All you have to do is take a look in the “Welcome Slots” section to see all the legendary slots they have on offer. Some of our favourites include:

  • Big Bass Bonanza
  • Fishin’ Frenzy MEGAWAYS
  • Diamond Mine
  • Starburst
  • The Dog House
  • Aloha: Cluster Pays
  • Fluffy Favourites
  • Rainbow Riches
  • Bonanza MEGAWAYS
  • King Kong Cash
  • Wish Upon a Jackpot

Beyond slots, Onyx does have some live casino games provided Pragmatic Play. If it’s your first time dipping a toe into the world of live dealer, and you’re not a huge fan of classic table games like Roulette, we recommend trying Boom City!

Final Thoughts

Onyx Slots is a brand-new Grace Media casino for April 2024. It is hot, hot, hot of the press with a stunning 5 times deposit welcome package. We appreciate the commitment to the Ancient Classics theme and we appreciate the quality of the slot games available. Try out the extremely fair welcome offer!
