If you’re struggling to access Black Diamond Casino, rest assured, you’re not alone. Many players have experienced the same problem, and the team here at GamBonus would like to explain the reason and your options going forward.
Black Diamond Casino closed its virtual doors in December 2022. It was owned by DeckMedia NV and originally launched in 2009. If you’re trying to log on, you need to take care. Should you follow any of the links in adverts or reviews of the now-defunct casino, you might be directed to other sites, some of which might or might not be bona fide or legit.
If you carry on searching, you’ll eventually discover that Black Diamond Casino is no longer operational. The exact reason for its closure is not known for certain, but some rumours suggest it was poorly managed from a business perspective. It’s also likely that it was operating without a bona fide gambling license, despite purporting to operate under a Curaçao license.
Unlicensed online casinos are a real no-no. It means there is no real player protection, potentially compromising player safety and security. If you’ve been surprised by its closure, you’ll find this alternative to Black Diamond Casino review helpful. In it, we discuss safe, trustworthy and reliable platforms to the now-defunct Black Diamond Casino, such as Boomerang-Bet Casino, Slotlords, and Winz.io Casino.
A Concise Boomerang-Bet Casino vs Black Diamond Casino Review

With Black Diamond Casino terminated and no longer available, Boomerang-Bet Casino is an excellent option to consider. Whereas Black Diamond only offered 800 slots and live dealer games, the Boomerang-Bet Casino game offering is numbered in the thousands. It covers slots, table games, live dealer games, and a comprehensive sportsbook, plus live sports.
Operates Under a Bona Fide Anjouan Gambling License
Black Diamond’s cardinal sin was not having a current gambling license. You have no such worries with Boomerang-Bet. They operate under an Anjouan Gambling License (ALSI-152406028-F12), a license that attracts many new start-up casinos thanks to its lower cost base. Boomerang-Bet has been around now for over 2 years, during which time, since Black Diamond Casino closed, it’s become a great option for ex-Black Diamond players.
Works With Over 100 Software Providers
Whereas the Black Diamond Casino closed platform chopped and changed the list of software providers they worked with, to their detriment, Boomerang-Bet Casino currently work with 101 game providers. They include all of the top names, such as Amatic, BTG, Evolution, Microgaming (now Apricot), NetEnt, Play’n GO, Pragmatic, Yggdrasil, and more.
In addition to claiming from 15 bonuses and promotions, you can choose from thousands of slots and table games, or you can try live sports betting, via Boomerang-Bet’s impressive, live sports betting platform. Also, each time you make a deposit, you get 1 free go at their Bonus Crab.
With Black Diamond Casino terminated, if you do want to give Boomerang-Bet Casino a whirl, you might like to claim one of their Welcome Bonuses.
The Boomerang-Bet Welcome Bonuses
There are 2 Welcome Bonuses, one for Boomerang-Bet’s casino, and one for their sportsbook.
- Casino Welcome Bonus 100% up to €500 plus 100 Free Spins
- Sportsbook First Deposit Bonus 100% up to €100.
The wagering on the Casino Welcome Bonus is 35x bonus plus deposit, and for the Free Spins, 40x, while for the Sportsbook First Deposit Bonus, it’s x bonus plus deposit.
However, you’ll be pleased to know that claiming Welcome bonuses is not obligatory. You can simply register a player account, deposit at least the minimum amount, skip any bonuses and get straight to playing, if that is your preference.
A Concise Slot Lords Casino vs Black Diamond Casino Review

Slot Lords Casino is more of a direct comparison to the Black Diamond Casino closed platform inasmuch as it focuses on slots, table, and live dealer games, without diverting its energy into sports betting. But with well over 5,000 games, Slot Lords easily outstrips the rather meagre, by comparison, 800-game offering of the Black Diamond Casino terminated site.
When carrying out casino reviews, the first thing the team here at GamBonus focuses on is player safety and security. Having done our due diligence, we are pleased to confirm that Slot Lords Casino operates under a CGA (Curaçao Gaming Authority) license – number OGL/2024/161/0191. It’s a well-established, reputable, and well-regarded license within the global online casino gaming world.
In addition to its 5,000+ games, their website is excellently designed, with easy shortcuts to hold-and-win slots, jackpot slots, top slot titles, including Megaways, instant win games, and new games. Slot Lords also covers all of the popular table games, as well as having an excellent live casino platform.
This casino also offers a host of ongoing bonuses, promotions, and tournaments. You can also fund your play with either fiat or cryptocurrencies.
If you’re considering registering with Slot Lords, as Black Diamond Casino has closed down its platform, this alternative has an attractive Welcome Bonus package that consists of up to €4,500 with the following split:
- Deposit 1: 100% up to 750 €/$ plus 100 Free Spins – Bonus code FIRST.
- Deposit 2: 125% up to 750 €/$ plus 100 Free Spins – Bonus code SECOND.
- Deposit 3: 75% up to 1,000 €/$ plus 25 Free Spins – Bonus code THIRD.
- Deposit 4: 25% up to 2,000 €/$ plus 75 Free Spins – Bonus code FOURTH.
The wagering requirement is 40x
Alternatively, if you prefer a Welcome Bonus with a lower wagering requirement, you could opt for their 120% up to 1,000 €/$ plus 100 FS Welcome Bonus offer, using Bonus Code ‘PLINKO.’
A Concise Winz.io Casino vs Black Diamond Casino Review

After Black Diamond Casino closed its doors once and for all, Winz.io Casino benefited when a number of Black Diamond devotees (especially those who like the idea of using crypto to fund their online gambling), decided to transfer their loyalty to them. Like Slot Lords, Winz.io operate under a CGA license, in this instance, license number OGL/2023/174/0082.
Winz.io – The No Wagering Bonus Casino
One of the big attractions of joining the Winz.io Casino crowd is the fact that, unlike most online casinos, none of Winz’s bonuses (including their Welcome Bonuses) require wagering. Add to that the fact that this platform offers over 6,000 slots and other games from the best software providers in the business, and it’s easy to see why we here at GamBonus are keen on them.
Before Black Diamond Casino closed its website and ceased trading, you would have had to accept a 35x wagering requirement if you claimed their Welcome Bonus. In other words, even if you made a minimum deposit of €20, you would have had to deposit another €700 before you could withdraw any winnings you might make from the bonus. Winz.io Casino’s Welcome Bonuses are wagering-free. There are 4 different Welcome Bonuses from which to choose:
- Welcome 20% Crypto Bonus.
- Welcome $10,000 Wheel of Winz.
- Welcome 10% Live Casino Bonus.
- Welcome 100% Sports Bonus.
So, if you’re looking for a new online betting site after Black Diamond Casino terminated, and you want to avoid being tied into Welcome Bonus wagering requirements, Winz.io Casino could be your best choice.
Where to Find the Best Live Dealer Games After Black Diamond Casino Closed
Black Diamond Casino’s live dealer game offering wasn’t as good as it could have been when the site was running, which is another reason the platform closed down. Live casino games have become really popular in recent years, especially with the improvement in mobile technology. It has made them easier to play wherever you might be, as long as you have access to a reliable internet connection. The 3 online casinos we’ve featured briefly above. All offer a superb range of the latest live dealer games, and since Black Diamond Casino terminated, they are the perfect answer.
- The Boomerang-Bet live casino platform offers 95 live dealer games. As well as the usual well-loved table games, they offer specials like the Crazy Time live game show.

As well as tried-and-tested classics like Baccarat, Blackjack, and Roulette, their live specials include spin-the-wheel game shows such as Money Time and Mega Wheel, Sweet Bonanza Candy Land by Pragmatic Play Live, and Crazy Time and Funky Time by Evolution Gaming.
- The Winz.io live casino platform comes out on top in terms of live dealer games, with well over 500 from which to choose. As well as top live game designers like Evolution and Pragmatic Play, they also work with Ezugi, Play Live, TV Bet, and WinFinity.
