4KingSlots is an online casino name that you don’t want to repeat multiple times in quick succession. It is a cryptocurrency online casino that also accepts many fiat currencies and seems to go out of its way to appeal to as many players as possible, something that we can definitely appreciate.

With a Curacao online casino license, 4KingSlots is able to offer its services to players all over the world, with the exception of just a few major regions, including the US, UK, and Sweden (see the tables below this 4KingSlots review for more info). It has lots of games, bonuses, and more, and is dedicated to meeting the strict requirements enforced by KYC and AML rules.

If the name Mirage Corporation N.V. sounds familiar, it’s because we recently reviewed one of this operator’s other online casinos, WCasino Online. We had a lot of issues with that site, noting that it was incredibly dated, riddled with errors (from spelling mistakes and formatting issues, to an entire sports book that seems to have disappeared) and more.

As a result, we didn’t have high hopes for 4KingSlots. But let’s be real here, Mirage is not a fly-by-night brand. It’s a respected operator that runs a number of highly-rated online casinos. It might not be up there with the likes of Direx, a brand whose casinos have appeared numerous times here on Coinbuzz, but those guys have set the bar pretty high.

In this 4KingSlots review, we’ll see how it compares to other sites owned by this brand and discover if it’s worth your time or not.


One of the biggest issues we had with 4KingSlots’ sister site was the aesthetic, and the fact that it looked dated and didn’t work very well. 4KingSlots doesn’t suffer from any of these issues. Firstly, it uses a medieval theme, with a logo that features a crown and a few promotional images showcasing scenes of castles.

It doesn’t go the whole hog like the masterful King Billy casino, which is one of our personal favourites, but we’re happy to see this theme being used again.

Secondly, the colour scheme is much cleaner here than it is on the sister site outlined above. It utilises two shades of green, which sounds terrible, but actually works well, and these colours are accented with whites and golds.

We feel that Mirage casinos make an active attempt to look different and to use unusual colour combinations, ignoring the layouts that have worked so well for others. This doesn’t always work and when it doesn’t, it seems like a terrible idea. But in this case, we can’t complain as it works really well.

Slots and Table Games

4KingSlots works with a huge selection of iGaming developers, creating a varied range of real money slots, table games, and interactive titles. Of these, some of the standout creators include Big Time Gaming. Habanero, NetEnt, Relax Gaming, Wazdan, Microgaming, Playson, and Blueprint Gaming. Players are invited to search by provider, which makes it easy to find games by your favourite creator, and the following menu options are also available:

  • All: An unfiltered selection of all 4KingSlots games. As there are a lot of titles to search, we recommend using one of the other menu options or selecting a few of your favourite creators.
  • New: All of the casino’s newest games are added to this section. Find yourself getting bored with the same-old? Not willing to spin Mega Moolah for the millionth time? Take a look at this section and see what’s on offer.
  • Jackpot: Many jackpot sections are very limited, often including only fixed jackpot games. You can still win a lot of money with these, but they are not as life-changing as progressive jackpots can be. 4KingSlots, on the other hand, is a Microgaming compatible casino, which means it has some of the biggest progressive jackpot titles in the world, including the massively popular, award-winning, and record-breaking Mega Moolah. It’s a game that regularly pays in excess of €10 million, and that jackpot can be won by any player on any spin.
  • Scratch Cards: Microgaming steps up to the plate again here, with a series of jackpot scratch cards that play just like the cards you can buy in your local shop. The difference is that every outcome is determined by a single click and you don’t need to scramble desperately for a spare coin or worry about cleaning up all those scrapings!
  • Table Games: Baccarat, Roulette, Sic Bo, Poker—take your pick of some of the best table games on the market. There’s not much more to say, except that 4KingSlots works with a host of big table game creators, so you’ll always have plenty of games to explore.
  • Video Bingo: There are only half a dozen games in this section and a couple of them are keno, not bingo. But there isn’t that much difference between the two and once you find a bingo game you like, there’s no need to search for another.
  • Video Poker: Deuces Wild, Joker Poker, Jacks or Better—Microgaming is one of the world’s best creators when it comes to Video Poker. You have plenty of options and while some of them are dated, most are great.
  • Video Slots: A huge section containing all of the brand’s video slots. You’ll have a lot to wade through here, so be prepared to use the other filters or search by provider instead.
  • Virtual Games: A handful of games that are based around table games or virtual sports. These titles are very hit and miss, but if you’re looking for something new, we recommend taking a peek.

4KingSlots Tournaments


All new players making qualifying deposits of €25 or more can secure up to €750 at 4KingSlots. This is separated into three deposits, all fixed at €250. The first offers a 100% match, while the second and third offer 50%. In addition, players can secure 100 Free Spins every time.

When you compare this offer to the big bonuses at Tsars Casino and other sites on our top list, it looks pretty tame. But we’re talking about €750 and 300 Free Spins here—unless you’re a high roller, that’s not an amount to be sniffed at!

As we often say, there is no difference between a €100 matched deposit bonus and a €10,000 matched deposit bonus if you’re only depositing €10! The minimum deposit requirement is a little high but it will accommodate most types of players.

The wagering requirements are set at 40x for the deposit and bonus and you have 15 days to clear this amount. All Free Spins are tied to one Habanero slot game and players cannot bet more than €4 per spin.

One of the things we like about this casino is its inclusion of Slots Races, which are basically real money tournaments. These give you an extra incentive to play and more chances to win big. You have no reason not to try them and if it’s your lucky day, you could walk away with hundreds of Euros in prize money! In addition, there are also regular tournaments offered by the operator and specific slot developers.

To top it off, 4KingSlots has a Loyalty Scheme. It’s not quite on par with the Loyalty Scheme offered at SlotsHeaven, but these schemes are always a welcome sight. You will earn 1 Loyalty Point for every €20 that you spend and you can swap 20 of these for €1. It’s a decent exchange rate and will help you to stack-up that cashback as you play your favourite games.

Banking Options

All deposits at 4KingSlots are processed free of charge, and without delay. You may need to wait up to 30 minutes for money to land in your account if you’re using cryptocurrencies, but in reality it rarely takes longer than ten minutes.

Payment options include all the usual traditional methods, such as Visa, Mastercard, Skrill, and Neteller, as well as cryptocurrencies like Ripple, Bitcoin, Ethereum, and Litecoin. These options may be a little slower when it comes to deposits, but they are very quick when it comes time to withdrawals and they also have higher limits.

Players in Canada can use Interac, mobile players can opt for Neosurf, and there are enough options here to satisfy most players.

4KingSlots is one of many casinos that asks for verification documents before withdrawals. This is something that seems to annoy many players but as we have noted before, it’s pretty standard. And it’s not a bad thing, as it shows that the casino is trying to abide by the strict Know Your Customer rules, which are there to prevent everything from money laundering to underage gambling.

Contrary to what some players seem to think, these processes are not there to prolong the withdrawal process or scam players in anyway. It’s true that many players get frustrated and end up gambling and losing all of their winnings, but it’s something that is out of the casino’s control. If they don’t abide by these rules, they risk losing their license.

Of course, you are within your right to feel frustrated and sense shenanigans if the casino takes an unnecessarily long time to review your documents and keeps returning them without valid reason. We’ve experienced this in the past and we’re sure most other gamblers have as well. But there are no such issues with 4KingSlots. Everything should be processed in a few days.


You cannot without more than €1,000 at a time on 4KingSlots and this increases to 0.5 BTC for Bitcoin users. This is a per transaction limit and the per week and per month limits seem to be higher, but we couldn’t get any actual clarification on this. We are able to say with relative certainty that the limits on 4KingSlots are much higher than the ones on sites like Cadoola Casino, but they still exist, and that is never a good thing.

4KingSlots Bonuses and Promotions

Reviews and Support

4KingSlots has accumulated quite a few user reviews since it launched in 2019. Most of these are positive and of the limited negative reviews that exist, very few have anything concerning to report. There are people complaining about bonuses not being very clear and winning streaks not being very frequent, but as we have noted many times before, these comments are common.

The only thing that concerns us is that 4KingSlots doesn’t respond to any of the negative reviews and doesn’t even acknowledge the positive ones. This is a big issue and it’s something that we have reported on previous occasions, including our Syndicate Casino review.

As noted on those occasions, it helps when a casino responds to negative comments. If you have an issue and you can’t get an answer from the customer support team, this is often the best way of navigating that support team and going direct to one that has more sway. Without that option, you’ll left banging your head against a brick wall, complaining to someone who doesn’t want to listen.

Responding to customer reviews is one of the best things that an online casino can do. It takes an hour or two every week for small casinos and betting sites and yet it makes a massive difference.


What Languages Can I Use?

The site can be accessed in both English and German. They are the only two languages accepted on this website.

What Currencies Can I Use?

There are roughly half a dozen accepted currencies here, including USD, EUR, and GBP.

Can I Play in the UK?

You cannot play here if you live in the United Kingdom. The same is true for many other regions and you can see a full list of restricted countries below this review.

Can I Play in the US?

You can't play here if you are in the United States, and it's not worth trying. The law is steadily changing though, so pay attention and you may be able to join sites like this before long.

Is it Licensed?

Of course! 4Kings is licensed by the authorities of Curacao, which means it is operating legally and is certified to be safe and fair.

Final Word

We weren’t expecting much when we first approached 4KingSlots. We didn’t have the best experience with its sister site and were expecting something equally disappointing here. Thankfully, that wasn’t the case, and we were pleasantly surprised with what we saw.

That doesn’t mean that 4KingSlots is the best casino out there, far from it. In fact, it is a long way off the likes of Wild Tornado casino and hasn’t made it into our top 20. But we have reviewed countless casinos and dismissed many more. The fact that it is here at all, and the fact that it has such a respectful rating, is proof of just how much we like this site and how much fun we had here.

Join 4KingSlots today using the links on this review. That will ensure you get the latest bonus, while also making sure you’re added to the casino’s Loyalty Scheme. There’s a lot going on here, a lot to enjoy, and we’re sure you’ll have fun exploring its many bonuses and games.
