K8 Review

How We Reviewed K8.io

We take our time here at CryptoSpinners, carefully crafting fair and objective reviews for all the trusted crypto casinos we come across. We test each site extensively, combing through the following points:

  1. License, safety & fairness
    With so many dodgy casinos out there, especially in the crypto space, establishing a site’s credentials is critical.
  2. Evaluation of offers & bonuses
    Every casino claims to offer the best bonuses – but how good are they really?
  3. Process to open a new account
    Signing up to a casino shouldn’t feel like pulling teeth, nor should it take hours. We’ll tell you what our experience was like.
  4. Cryptocurrencies supported
    If you’re going to call yourself a ‘crypto casino’ these days, you need to accept more than Bitcoin and Litecoin! We’ll let you know how ‘crypto’ the casino really is.
  5. Assessment of the games and providers’ selection
    Let’s face it, not all casino games are created equal. Some providers are leagues ahead of others, and we want to see both quality and quantity.
  6. How to withdraw
    Most casinos make it easy to deposit, but withdrawing should be just as easy. After all, it’s your crypto!
  7. Investigation of the customer support
    Too many casinos don’t invest enough in player support, and we don’t like that. We want to see several contact methods, including live chat and email, and ideally a freephone number too. Are the staff professional and knowledgeable too?
  8. Responsible gaming tools available to players
    All good casinos take responsible gambling seriously. We want to see easy-to-use player management tools, clear advice, and links to additional help resources.
  9. Awards won
    Okay, so, we can’t expect all casinos (especially new ones) to have a cabinet full of trophies in their boardroom – but, it’s definitely a plus if they do!
  10. Overall gaming experience
    All things considered, how do we feel this casino stacks up against the competition?

K8’s Licences, Safety and Fairness

K8 has the Following Licence

  • Gaming Curaçao (#365/JAZ)

What Makes K8 Safe?

It was easy to learn that K8.io is operated by Curaçao-based Westward Way Tech N.V., and that Apollo MKT Limited provides payment management and support services related to operating the site. SSL encryption secures your connection, ensuring privacy and safety. It appears you’re in good hands.

It’s also worth noting that K8 has had ample time to make a name for itself in the crypto gaming space. Since 2013 it’s remained a trusted vendor of cryptographic fun. Although a Curaçao license holds little weight in the online casino industry, they’ve gone to great lengths to keep their customer base happy. Any other license will require the casino to undertake cumbersome KYC checks on you that will negate the purpose of using your crypto to play.

Opinion: Proof Positive
These guys have had a lot of time to make improvements to their product. They were there in the early days – when cryptocurrencies made no sense to anyone on Earth, at all – fending off criticism from the OGs (Original Geeks) to make a name for themselves as a leading crypto casino.

Welcome Offers and Bonuses at K8.io Casino

Welcome Offer: Up to $3000

K8.io only takes cryptocurrencies, so the $3000 bonus requires a little more explaining on our part…

Once you’ve registered, you’ll be asked to deposit crypto. They take a variety of the major tokens – up to 18 – so you should be well accommodated. Just click ‘Choose your bonus’ and select the offer, then make your deposit (at least 0.001 BTC), and you’ll receive a deposit match bonus of 100%, up to $3000 equivalent to the cryptocurrency you deposited.

As to be expected, the welcome bonus is subject to wagering requirements but they’re 30x, which is roughly the industry standard. As with most casinos, there are limits regarding which games count towards meeting your wagering requirements. In their words, “The running water of blockchain games is not counted” but that’s about it.

Other K8 Promotions and Tournaments

What’s particularly impressive about K8.io is the sheer number of promotions they run. There are a few on offer, as of publishing this review (Jan 10th, 2023):

75% Cash Back Up to 1,000 USDT! – ending Jan 31st, 23:59 UTC

“Throughout the duration of this event, all K8 members who made a second deposit worth $50 or more will receive a 30% cashback, additionally members who deposit for a third time worth $50 or more will receive a 45% cashback. After making the deposit, members must contact our customer support team to apply for this promotion.”

And then there are ongoing promotions, like:

K8 No Deposit Bonus

Though there is no registration bonus – one rewarded to you before you’ve made your first deposit – they do have a Birthday Bonus which is awarded to players on the anniversary of their registration. They also have a Daily Reload that randomly rewards VIPs.

K8 Rakeback Bonus

The casino boasts both a Rakeback & Double Rakeback bonus. The Rakeback amount is calculated in real time and can be claimed from the VIP menu.

K8 Loyalty Club and VIP program

As you probably gathered from the above promotions, K8’s VIP program is alive and kicking. But this team has kicked things up a notch.

K8.io VIP Benefits
An exclusive offer for VIPs

Going above and beyond the industry standard, K8 shifted earth to offer VIP members 100% off of up to 3 subscriptions.

Their program has been split into five tiers, named after precious metals (of course) – Bronze, Silver, Gold, Platinum, and Diamond.

Players qualify for these tiers based on their total turnover:

  • Bronze – $10,000
  • Silver – $50,000
  • Gold – $100,000
  • Platinum – $250,000
  • Diamond – $25,000,000

Both Platinum and Diamond are split into 6, and it’s Platinum upwards when players can start to have their subscriptions paid for:

  • Platinum 1 – $12.99 (for one subscription)
  • Platinum 3 – $26.98 (up to two subscriptions)
  • Platinum 5 – $39.97 (up to three subscriptions)
Opinion: Very Important Program
Although their welcome bonus is somewhat modest, when it comes to other bonuses and promotions, K8.io soars to new heights. They recognise just how competitive the crypto casino market is, and they’ve done well to not only keep up but leap ahead.
