The casino industry is full of colourful and relatively pointless themes. Slots are a great example of this. They use all kinds of weird and wonderful themes and try to tell intricate stories, but these narratives rarely extend beyond the intro and a few basic images. The same is true for online casinos, with the themes typically limited to a logo, a flashy home screen, and little else.

King Billy is one of the few exceptions to this rule and a personal favourite of ours. It is set in an ancient kingdom ruled by the eponymous leader, and this medieval theme weaves a coherent thread throughout the website.

…a personal favourite of ours.

There are scrolls stamped with molten wax and highlighted by candlelight, stories of King Billy’s land and life, and a loyalty scheme that adopts a similar vibe. It’s still an online casino, so don’t expect an epic adventure with dragons, chivalrous knights, and an RPG level-up system, but the theme works great.

It will appeal to fans of fantasy worlds, as well as anyone who enjoys a clean theme with crisp graphics and great features.

King Billy is regulated by the authorities of Curacao (for crypto) and the Malta Gaming Authority (for everything else) and is available for players across many key gambling regions, with the exception of countries like the United Kingdom, United States, and Sweden. It seems to target the Northern European market, as evidenced by its inclusion of Scandinavian languages and currencies, and it also attracts a lot of customers from Canada and New Zealand.

All new players are welcomed into King Billy’s kingdom with a four-tier Welcome Bonus, offering a total of €1,000 along with 200 Free Spins. This bonus is structured as follows:

  • 100% up to €200 (or 1 BTC) with 200 Free Spins
  • 50% up to €200 (or 1 BTC)
  • 25% up to €300 (or 1.5 BTC)
  • 25% up to €300 (or 1.5 BTC)

Known as the Big Four Bonus, this is a great way to introduce yourself to King Billy. You can use the bonus credits to play slots, table games, and more, while the Free Spins, which are released at a rate of 20 day for 10 days, can be used on Fruit Zen and Starburst.

You will need to wager 1x your bonus amount within 23 hours to collect your first bundle of Free Spins. If you deposit €100/0.5 BTC, for instance, you’ll get a total of €200/1 BTC to play with and when you wager €100/0.5 BTC the first 20 Free Spins will be released.

king billy casino withdrawal reviewsA 30x wagering requirement applies to the bonus and there is a minimum deposit of €10/BTC 0,0003 and a maximum bet of €10/BTC 0,0003 per spin. You have a total of 30 days to clear this bonus and can only withdraw your winnings when these terms have been met.

Along with this generous Welcome Bonus, King Billy has something known as the Slot of the Month. This bonus gives you 61 Free Spins on a pre-selected slot machine, one that changes every month.

To qualify, you just need to deposit a minimum of €20/BTC 0,0006, after which you will need to clear a wagering requirement of 30x. There is no maximum win for this bonus, so if you meet the wagering requirements then you will can keep all of your winnings (or whatever is left after those requirements have been met). It can also be collected once per week, although it does not apply for cryptocurrency users.

In fact, there are several other bonuses available at King Billy, including cashback and Free Spins, and these are also not available for cryptocurrency users.

Obviously, this is a pretty big negative, considering we’re a Bitcoin casino site and most of the people reading this are Bitcoin users, but don’t worry as the Welcome Bonus still applies and there is also a very generous Loyalty Scheme.

Known as the VIP Club, this scheme is spread across 5 tiers:

  • Citizen
  • Baron/Baroness
  • Duke/Duchess
  • Prince/Princess
  • King/Queen

You’ll get points every time you play and the higher up the rankings you go, the more points you will earn and the greater the rewards will become. For instance, once you advance to the second level, you’ll get 200 Free Spins, while the third offers 300 spins and 7% Cashback, and the fourth provides 10% cash back and a massive €350 wager-free bonus.

The final level, where you sit alongside the king in his throne room, is invitation only and comes with a surprise bonus and a massive 13% weekly cashback offer.

Games and Software

Betsoft, NetEnt, and Quickspin are three of the biggest providers at King Billy. All of these developers are known for producing beautiful and innovative slots, from Betsoft’s The Slotfather and Max Quest to Quickspin’s Big Bad Wolf and NetEnt’s Gonzo’s Quest.

These two developers are supplemented by Red Tiger Gaming, Thunderkick, Ainsworth Gaming Technology, Booming Games, Pragmatic Play, Yggdrasil Gaming, and Tom Horn Gaming.

Microgaming is also here, but unlike many other Microgaming casinos, this major developer doesn’t take centre stage. King Billy has cherry-picked some of its best games and these are hosted alongside games from the star-studded creators mentioned above.

All King Billy games are neatly arranged, making it easy to find your favourites. You can use the “Provider” tab to browse through multiple creators, including all of the aforementioned. This way, you can select your favorite creators and make sure you only see games that they have created.

The “New” and “Top” sections are also great if you’re not sure which games to play, with the former focusing on the latest additions to the King Billy casino and the latter looking at popular titles like book of Dead, Gold Rush, King of 3 Kingdoms, and more.

You will notice that there is also a “Live” section here. This is where you will find King Billy’s Live Casino games, provided by the likes of Evolution Gaming.

The King Billy Live Casino includes all of the following games:

  • Poker: From Texas Hold’em to Stud Poker and Draw Poker, this hugely popular game features in all of its glory here.
  • Blackjack: A simple but brilliant card game where the goal is to hit 21 and beat the dealer. You can play classic variations, multi-card options, and more, all facing-off against a real dealer.
  • Baccarat: Speed variants and Punto Banco variants are both available, along with countless others.
  • Roulette: Spin the wheel with a host of popular Roulette variants, including variations of French and American Roulette. This is where the Lightning series really comes into its own, as Lightning Roulette is one of Evolution’s standout titles.
  • Game Shows: These games offer something a little different, and are great if you’re seeking a more immersive experience, one that doesn’t involve dice, cards, or slot machines. The games available here include Football Studio, Monopoly Live, and Deal or No Deal Live.

If you prefer the simplicity and speed of virtual table games, give the Live Casino variations a miss and click onto the “Table” tab instead, where you’ll find all popular card, dice, and wheel games in a streamlined format.

One of our favourite things about King Billy is the inclusion of slot tournaments. These are available every day and reward you every time you take a spin on the reels. You’ll need to play specific slots to qualify and there are also minimum bet limits, but when you play, those points will roll in and you’ll climb the leaderboard.

Make it to the top of this leaderboard and you can start collecting big prizes. These tournaments are often based on bet amounts and not win totals, which means they tend to favour higher rollers. In fact, the average minimum bet is €1, so they are out of the question for micro stake players. But everyone who regularly plays above these limits has a chance of winning big.

king billy casino games reviewsTake a look at the King Billy Tournament section to learn more. You’ll find info on the current qualifying slots and rules, as well as a clock showing you how many hours you have before the daily tournament finishes.

Payment Methods

You can choose from two dozen different deposit methods at King Billy, including all of the following cryptocurrencies:

  • Bitcoin
  • Bitcoin Cash
  • Ethereum
  • Litecoin
  • Tether

King Billy is also a fiat currency casino. In fact, as noted above in our bonuses section, the casino actually seems to favour players who use fiat currencies, with options such as Visa, MasterCard, WebMoney, Sticpay, ecoPayz, QIWI, Neosurf, PaysafeCard, Skrill, and iDebit. Most of these can be used to withdraw, as well, and King Billy also accepts Interac withdrawals, which is one of the most popular methods in Canada.

Deposit limits are typically fixed at a minimum of €10 and a maximum of €4,000 per transaction, while withdrawals must be at least €20 and can be as much as €4,000 per transaction. These limits may change depending on the currency chosen and the payment method.

You won’t pay any fees for deposits or withdrawals, but if you’re using a credit card, you may be charged by your provider when you make a deposit. Withdrawals are instant with most payment options but can take up to 3 days with slower methods like bank transfers. It’s also worth noting that some withdrawals will be subject to a short pending period, although this rarely lasts more than a few hours and even in extreme cases it doesn’t extend beyond 24 hours.

Everything Else

King Billy is owned and operated by an experienced casino company, one that operates over a dozen other brands. It operates under license from the authorities and has a multitude of awards and certifications. It has been verified as a safe and fair online casino by independent authorities and also takes responsible gambling very seriously.

The King Billy support team is always on hand when you need them. Live Chat is active 24-hours a day and there is also a support email address.


How Can I Contact King Billy?

You can contact King Billy customer support via Live Chat, which is active 24/7.

Can I Join from the UK?

King Billy is not available to players in the United Kingdom. There are a few other restricted regions as well. Take a look at the table below this review for more info.

Can I Use PayPal?

It's rare to find PayPal accepted on casinos regulated outside of Europe, and such is the case with King Billy. You cannot use this payment method, but there are others available.

Can I Use Bitcoin?

Of course! It is the main payment method accepted at King Billy and can be used for both deposits and withdrawals.

How Do I Advance Through the VIP Program?

Just keep wagering and playing but don't bet more just to earn points. As with all Loyalty Schemes, the points you earn are small in the grand scheme of things. They should be considered as a unexpected bonus and nothing more.

Are There Other Sites Like King Billy?

It's a great site but it's not alone in terms of having a medieval theme and a great VIP Scheme. We recommend checking out Kingdom Casino, which is very similar.


Despite being launched relatively recently in 2017, King Billy has come a long way and is considered one of the biggest and best Bitcoin casinos on the market.

It is not perfect, far from it. If you’re using fiat currencies, it’s ideal and there are very few issues worth highlight. If you’re using Bitcoin or other cryptocurrencies, however, there is one major flaw: the bonuses. While you can collect the Welcome Bonus and be part of the Loyalty Bonus, you can’t take part in the regular Free Spin offers and Reload Bonuses.

This is a bit of a downer, but when you consider that Bitcoin players can scoop bigger Welcome Bonuses than their fiat currency counterparts, it all balances out in the long run.

The fact that King Billy is not available in the United Kingdom is another negative, and you also can’t join King Billy if you reside in France, Belgium, Sweden, Spain, and more.

But if you’re not located in these countries and are looking for a new Bitcoin online casino, click onto King Billy. Just remember to keep a close eye on the Loyalty Scheme, collect as many points as you can, and make sure to use your points and collect your rewards when they are available.

Easily the best loyalty scheme that I have joined. I don’t even gamble that much money and I have still been able to take advantage of it. The main bonus is decent as well. It’s hard not to like this site!

When I first saw this site, it reminded me of those crappy mobile games that always advertise themselves with great graphics and bizarrely unique gameplay, only for you to discover that it’s actually a basic puzzle game that has nothing to do with anything (you know the ones I mean).

Thankfully, it was nothing like that. In fact, the graphics grew on me and I agree with the reviewer that they are some of the best around. I would have preferred more of a rustic edge in tune with the medieval style, but it looks fantastic nonetheless.

I didn’t have much luck when I first joined and I messed up the bonus, but the support team was very helpful and fixed it for me. After losing all my deposit, I very nearly walked away, but then I found the loyalty scheme and decided to stick around.

Today, it’s one of the few casinos that I use on a regular basis and that’s all down to the loyalty scheme. The games are okay as well (but let’s be honest, you can find the same ones everywhere else) but the support and the loyalty scheme are what set this site apart from the rest.

to be honest, i never really bothered with the loyalty program here.

i dont think that i gamble enough to get anythign from it because i just havent been able to collect anything.

not a bad thign tho as the same is true everywhere else. on the plus side, the site has some great welcome and reload bonuses and they are definiately good for me.

Great review! I personally prefer Kingdom Casino as this one just never stood out to me, but it’s okay. I think there are better loyalty programs out there, but I supposed it’s each to their own!

2 years ago

My personal favorite. To be honest, I never paid much attention to the loyalty scheme until I saw this review. The other bonuses are great though and it has a good selection of games.

I felt that they could have done a little more with the theme. I like it, but it’s not quite medieval and i have seen better VIP programs. It’s not a bad site, far from it, but I don’t think it’s quite the best out there as many seem to be claiming

I feel like this site isn’t as good as it used to be. Not as generous. Or maybe I’m just bitter because it has been a while since I won.

It used to be my fave site. Still up there tho.

I used to love pretty much everything about this site. I feel like it has gone downhill somewhat lately though. The bonuses and games are still good but I feel that the customer support could use some improvements.

I saw that “Not Available in the UK” after reading this review and getting excited about the welcome bonus and loyalty scheme. Such a shame as this looks like it would be perfect for me

Would love your thoughts, please review.x
