Game Providers

Now, this is where things get interesting, as the games and slots are really what we all are after.

Ideally, we want an online casino where we can play all our favourite slots in a fair way with additional jackpot games from leading game studios mixed with the latest releases.

So, let’s have a look at what King Billy offers.

At first glance, the game selection offered at King Billy looks impressive as there are well over 2,000 slots on offer, but once we look closer, we can see that some leading game studios are missing.

But let’s start with the existing game studios found at King Billy:

  • Pragmatic Play
  • Nolimit City
  • Relax Gaming
  • NetEnt
  • Big Time Gaming
  • Avatar UX
  • Thunderkick
  • Playtech
  • Evolution (Live Casino)
  • Quickspin
  • Red Tiger
  • Betsoft
  • Playson

This is an impressive line-up of game developers, and there are even more. In total King Billy offers games from more than 50 game studios.

We already mentioned the most established ones, but some of the less known to the broader public include game providers like Fugaso, Gamebeat, Quickfire, and Wazdan.

What about the leading game studios that are missing at King Billy?

Well, these include slots from Play’n GO, Hacksaw Gaming, Push Gaming, ELK Studios, iSoftbet, Yggdrasil, and Microgaming.

So if you want to play Book of Dead with the best RTP, you will have to look elsewhere.

However, finding top games to play at King Billy won’t be an issue as you can find titles like:

  • Gates of Olympus – One of game studio Pragmatic Play´s most played online slots. In this Ancient Greek Gods-themed game, you want Zeus on your side to help you increase the global multiplier in the Free Spins to achieve big wins. The Max win is 5,000x your bet per spin.
  • East Coast vs West Coast – One of the most entertaining online slots released in recent years with a colossal max win potential of up to 30,618x your stake. In this Hip-Hop themed Nolimit City slot, you can play with features like xWays and xNudge Wilds.
  • Bonanza – The slot that brought game developer Big Time Gaming to the limelight in the online casino industry. A super entertaining Megaways slot where you need to land the letters GOLD to trigger the Free Spins, for a chance to win up to 12,000x your bet.

With such an extensive slot offering, it would help with some categories to choose between, and King Billy has some of these ready for you.

You can find games from categories like:

  • New
  • Top
  • Jackpots
  • Provider
  • Slots

It’s also possible to find games through the user-friendly search bar.

Is there anything else you should know about the slot selection?

The Big Time Gaming slots are listed as Relax games since King Billy cooperates with Relax Gaming´s game platform, Silver Bullet.

A bit sloppy not to categorize those slots properly, but no biggie. However, now you know if you might wonder why Big Time Gaming isn’t available among the providers listed on the site.

Safe Gambling: Is King Billy Casino Safe?

King Billy Casino is a multi-award-winning online casino that has gained an excellent reputation among players and the industry and is considered a safe casino.

The Curacao gambling license that King Billy has obtained allows the operator to function on the international market.

However, compared to some local gambling licenses like the UKGC, the Curacao license is much more relaxed with the operators with certain requirements, and fines are pretty much unheard of.

So while the Curacao gambling license is respected and considered a safe option, it doesn’t give full player protection like a UKGC license would do.

Meanwhile, this also means fewer documents might be required from a Curacao-licensed brand compared to some other jurisdictions.

Responsible Gambling is still a major topic in the online casino industry, and King Billy offers players different options to help their customers control their gambling.

King Billy wants the entertainment factor to be central while preventing any harm.

Some tools that you can access include personal limits like deposit, loss, and wager limits, cooling-off periods of 1 day to 6 months, and complete self-exclusions from the site.

King Billy also promotes help organizations like Gamblers Anonymous, GamCare, and Gambling Therapy; links can be found on the responsible gaming page in the site’s footer.

KYC and Documents

Verifying your identity when playing with cryptocurrencies is often not necessary, but in some cases, King Billy might require you to send some documents.

This usually happens in conjunction with a withdrawal request.

When playing with Fiat currencies like Euros, a Know Your Customer (KYC) procedure is standard practice, though.

Again, usually in combination with a withdrawal request which generally exceeds $/€2,000.

When the KYC is requested, you are expected to send a copy of your government-issued ID, passport, or driver’s license.

On top of this, proof of address and a copy of a recent bill or photos of the banking option could be asked for as well.
