A new grey zone casino with a GREAT welcome bonus 

By Casinomeister, Last updated May 7, 2024

Casinomeister's Verdict

KoiCasino is a new cryptocurrency casino. When writing this KoiCasino review, we placed it in the grey zone here at Casinomeister. We have no immediate concerns about the site but don’t have enough experience with it to recommend it unconditionally.

This KoiCasino review will look at what we know about the site so far. Expect this review to be updated in the coming months.

First Impression

When we first landed on the KoiCasino website, we were greeted by what we’ve become used to seeing in today’s online gambling world. The website’s design is user-friendly, and easy to navigate, and everything is displayed clearly. At the bottom of the page, you will see a strange-looking navigation menu with links to different games and promotions. There are also buttons to log in to your account or register if you are a new player.

KoiCasino offers a generous welcome bonus. New players can claim a 100% matched deposit bonus of up to €500. Most notably, however, is that all KoiCasino players are eligible to claim 15% cashback every time they play. That’s incredibly generous, and it means that even losing sessions don’t necessarily result in your bankroll being wiped out.

KoiCasino offers a variety of payment methods, and you can deposit a withdrawal using all major credit and debit cards. This includes Visa, MasterCard, and Maestro. Other payment methods include Skrill, Neteller, and Klarna. KoiCasino also accepts cryptocurrencies, including Bitcoin, Ethereum, Litecoin, and Bitcoin Cash.

When we were writing this KoiCasino review, we found a ton of game developers on offer. This includes Pragmatic Play, Spinomenal, Relax Gaming, Hacksaw Gaming, Alchemy Gaming, Big Time Gaming, Red Tiger Gaming, Stormcraft Studios, Blueprint Gaming, iSoftBet, Thunderkick, NetEnt, Microgaming, 1X2 Gaming, Quickspin, and Evolution Gaming.

KoiCasino mainly focuses on video slots but also has a solid live casino and a few table games. Later in this review, we will look at some of the different games available.


  • Generous welcome bonus

  • Most major cryptos accepted

  • Fast cashouts

  • 15% cashback whenever you play

  • Granted Estonian license and accepting Estonian players


  • Curacao licensed


To see a breakdown of the different bonuses and promotions available at Koi Casino, you simply need to hit the “promotions” tab on the bottom right corner of the page. Below, we’ll be looking at some of the different bonuses currently available at the casino.

Welcome Offer

Like most reputable online casinos, Koi Casino offers a new player welcome bonus. All new players can claim a 100% matched deposit bonus on their first deposit and up to €500 in bonus funds. This welcome bonus is easy to claim; you simply need to create an account, head to the bonus section, and complete your first deposit. The bonus funds will be automatically credited to your casino account, and you are then free to begin playing your favorite games. Daily cash-back of up to 15% is also a nice addition to the bonus selection.

Welcome bonus for Canada and New Zealand is 100% up to $1000 and there’s up to 15% daily cash-back reward on top, for these players as well.

Koi Casino does a pretty good job of ensuring its terms and conditions are as easy to understand as possible. The wagering requirements of the bonus are 25X the total bonus plus the deposit amount. The wagering requirements must be completed within seven days, or any remaining bonus funds will be forfeited.

Koi Casino’s general bonus terms and conditions apply, which can be accessed through the terms and conditions link in the footer section of their website.

No-Deposit & Free Spins Offers

At the time of writing this Koi Casino review, we did not see any no deposit bonuses or no deposit free spins promotions. We will update this review accordingly if this changes in the future.

VIP and Loyalty Programs

In recent years, many cryptocurrency-focused casinos have been stepping away from the conventional VIP or loyalty program. Many sites are starting to offer loyalty schemes that all players can benefit from, regardless of their status or the amount of money they spend.

That is precisely what Koi Casino has attempted to do, and instead of a VIP or loyalty program, they allow all players to claim up to 15% cashback daily. This is a decent promotion, and it doesn’t matter how much you lose; you will always be able to claim 15% cashback on your net losses.

Unfortunately, the cashback is not wager-free. All cashback money must be wagered ten times, and these wagering requirements must be completed within one day of the cashback being credited to your account. The bonus cash back money is automatically credited to your account. However, sometimes, we have read reports that players need to manually claim it themselves from within the bonus section at Koi Casino.

It’s unclear whether Koi Casino operates a VIP program for high-roller players. Most casinos have special invite-only VIP programs in place for their highest-value planes, but Koi Casino doesn’t publicly state whether this is the case with them or not. If you have questions about the cashback scheme and want to know more about the potential VIP program at Koi Casino, we suggest you contact the customer support team directly.


Koi Casino offers a pretty standard selection of payment methods, and you can make deposits and withdrawals using all major credit and debit cards. They accept Visa, MasterCard, and Maestro. Deposits made from a credit or debit card are usually free – Koi Casino does not charge fees. However, your bank or card issuer may charge you a fee if you deposit in a non-local currency.

Koi Casino offers several EWallets, too, including Skrill and Neteller. However, you should be aware that if you use an e-wallet to deposit, you will probably not be eligible to claim the main welcome bonus. Always contact the casino directly if you have any questions about this.

The minimum deposit limit is not publicly stated, but we suspect it will be $10 or equivalent. Koi Casino also allows you to make deposits and withdrawals using cryptocurrencies. They accept Bitcoin, Litecoin, Ethereum, and Bitcoin Cash when writing. Cryptocurrency transactions at Koi Casino are completed immediately, and no fees are charged. We believe the minimum deposit could be as low as five dollars, but again, it is best to double-check with the casino to be sure.

Withdrawal Speed

Withdrawals at Koi Casino are processed quickly. Koi Casino will often process your withdrawal request immediately if you withdraw using a cryptocurrency. The processing time can take up to 48 hours for all other payment methods. However, from what we have seen from other players, pending times rarely take this long.

There is a maximum daily withdrawal limit of €10,000, and while we typically don’t like maximum withdrawal limits, this is relatively high. You can withdraw €70,000 per week means players should run into too many issues. It’s unclear whether progressive jackpot wins are subject to the same maximum withdrawal limits.

Responsible gaming

Unfortunately, the responsible gambling page at Koi Casino doesn’t offer much information about how they aim to help problem gamblers. They offer a detailed checklist (which you can use to get an idea of whether your gambling may be becoming problematic). Still, it doesn’t appear that they offer players the ability to set deposit limits, loss limits, or wager limits.

The only tool they appear to offer is a general account closure. However, even this can’t be done by yourself. You need to contact the online casino site’s customer support team directly. This is something we always frown upon. In our opinion, players should be free to close their accounts themselves at any time. Adding an extra step like this is, in our opinion, just unnecessary.

Customer support

Koi Casino has a customer support team working 24 hours a day, seven days a week. This is something we like to see. It means you can get help and support no matter what time of day (or night) you’re gambling. The online casino offers customer support in two ways. Firstly, you can reach the customer support team through email.

However, email response times can be slow. It’s much better to use the live chat system. This will connect you with a trained customer support rep in seconds. You can then talk in real-time with a customer support team member. This ensures you do not have to wait long to receive a response.


Koi Casino has a dedicated page for age and verification. This isn’t something we always see, and it’s refreshing, to be honest! Here is what Koi Casino has to say about its verification (KYC) checks:

In some circumstances, it may be necessary for us to verify your identity or age through a manual inspection of documents, and we reserve the right to request such documentation at any time. Reasons for doing so include, but are not limited to, the processing of withdrawal requests, fraud prevention, payment method queries, account and transaction reviews, and complying with our age verification licensing obligations and our crime and fraud prevention policies.

If we cannot complete our age and identity verification process satisfactorily, we may ask you to provide personal identification documents to confirm further and validate your age and identity. Such documents may include (but are not limited to): a passport or driving license, a current utility bill, or a bank or card statement. We may suspend your KoiCasino.com account until you satisfactorily complete these checks.”

Koi Casino doesn’t give any time frames for processing KYC documents. However, we can gather that most players find their accounts verified within 24 hours of submitting their KYC documents.

Website Experience and Features

If we’re being honest, Koi Casino reminds us of LeoVegas’ website. It’s not a copy – but the way the games are displayed makes them look similar. Nonetheless, Koi Casino is well designed and easy to use. We like that it’s pretty easy to navigate, and this is made possible through the two navigation menus; one at the top of the screen and one at the bottom.

The website’s color scheme is light orange and white. The main “games” page is well designed. Browsing through all the casino games is simple, thanks to all the different game categories. There are tons of subsections such as “Slots,” “Popular,” “Live Casino,” and “Table Games.” A search function also allows you to look up games directly by name. Unfortunately, there is no option to narrow down the selection of games by studio or provider.

Signing up for an account at Koi Casino is simple and takes just a few minutes. Whether you want to enter the live casino, the mobile casino, or play casino games from Pragmatic Play, you’ll be able to do so in a couple of minutes. Once you’ve verified your phone number or email address, you can make your first deposit and begin playing immediately.

While Koi Casino doesn’t have a dedicated mobile casino app, its website is fully mobile-optimized. This allows you to enjoy playing in a mobile-optimized version of the site. To access the mobile casino, you simply need to open your mobile device’s internet browser and head directly to the Koi Casino website.

We found the loading speeds quick, and everything works as it should. We also like that you can change the site’s language at the bottom of the screen. English, German, Polish, Norwegian, and Finnish are the current languages available, as well as two different English variations (Canadian and New Zealand.)

Brand games


Koi Casino offers games from a varied selection of software providers. This includes Pragmatic Play, Spinomenal, Relax Gaming, Hacksaw Gaming, Alchemy Gaming, Big Time Gaming, Red Tiger Gaming, Stormcraft Studios, Blueprint Gaming, iSoftBet, Thunderkick, NetEnt, Microgaming, 1X2 Gaming, Quickspin, and Evolution Gaming.

Below, we will look at some of the different casino games you can play at Koi Casino. First, look at some of the casino’s top video slots.


A glance at the popular games tab shows Koi Casino is primarily slots-focused. At the time of writing, the most popular video slot available is Big Cat Rescue Megaways. This is a game produced by Red Tiger Gaming, with six reels, between two and seven rows. It’s powered by Big Time Gaming’s Megaways mechanic, which means there can be up to 117,649 ways-to-win active on each spin.

In case you’re unfamiliar with Big Cat Rescue Megaways, the game is based around Joe Exotic and Carol Baskin – stars of the hit Netflix TV show Tiger King. The game can be played from as little as $0.10 per spin, and the maximum bet is relatively low at $10. The game has an RTP of 95.75%, and the maximum win is 10,481 times your total bet.

To be fair to Red Tiger Gaming, Big Cat Rescue Megaways looks fantastic. The reels are set on top of a backdrop that looks to be a big cat sanctuary. There are plenty of bonus features to look forward to, and the first is called the White Tiger mega wilds. Three of these mega wilds can land at once, and when they do, they show a multiplier that combines against other multipliers on the screen. This allows for mega wins, as the multiplier can reach up to 340X!

The main bonus feature in the game, however, is the free spins feature triggered by landing three or more of the scatter symbols anywhere in view. You will then get to spin a giant free spins wheel which awards you between seven and 22 free spins. A separate wheel will also spin, which determines your starting multiplier. The multiplier can reach up to 10 X.

Some of the other popular video slots currently available at Koi Casino include Cash Bonanza, Volatile Vikings, Bit of Horrors, Sweet Bonanza, Hot Chili, Gates of Valhalla, Wild West Gold Megaways, Merlin’s Revenge, Western Gold 2, Jester Wheel, Sizzling Eggs, and Gladiator Legends.

Live Dealer Games

Koi Casino uses Evolution Gaming to power their live dealer casino. We’re always happy to see Evolution Gaming offered at online casinos. They are, in our opinion, the clear market leader in the live dealer games industry. For example, their state-of-the-art technology means you can enjoy multiple camera angles while playing. All of their live dealer games use a high-definition camera, too, so you never have to feel far away from the action.

Evolution Gaming offers all of the standard live dealer games; you’ll find a wide variety of blackjack, baccarat, and roulette. However, it’s their more creative, unique games that they’re best known for.

For example, take Monopoly LIVE. This Hasbro-licensed live casino game is built around the famous board game of the same name. It also combines a bonus round you’d see in a video slot with a wheel of fortune-esque live game! You can win thousands of times your stake during the bonus round, and it’s become one of the game developer’s most popular live dealer games.

Other live dealer games you’ll find at Koi Casino include Crazy Time, Football Studio Live, Mega Ball, Lightning Roulette, and Lightning Baccarat.

Table Games

The casino table games at Koi Casino can be found under the “table games” tab. Here, you will find around 25 different casino table games. These casino table games come from game studios like iSoftBet, EGT, Electric Elephant, and Microgaming.

At the time of writing, we found: Tens or Better, Roulette 2X, Vegas Downtown Blackjack, Auto Roulette, Premier Blackjack, Deuces Wild, Turbo Auto Roulette, Millionaire Roulette, EGT Roulette, EGT Roulette DP, Jacks or Better, Blackjack Royal, European Roulette, Gamevy Blackjack, Jacks or Better, Classic Blackjack, and Back Blackjack.

Progressive jackpots

Unfortunately, Koi Casino doesn’t offer any progressive jackpot games – not that we could find, anyway. We don’t know why this is. In today’s online gambling world, progressive jackpot games are crucial; we would say, to make sure that players can play what they want.

What’s stranger is that Koi Casino already works with game developers like NetEnt and Microgaming, producing some of the world’s most popular progressive jackpot video slots. It wouldn’t take much for them to begin offering them.

In the future, we would like to see Koi Casino adding progressive jackpot games to their game library. It’s quite a downside, in our opinion, not offering them.

About the Team and History

KoiCasino is an online casino owned and operated by NJORD Ventures B.V. They are a company registered in Curacao. Unfortunately, their online gambling license is also from Curacao. Generally speaking, we don’t like Curacao licenses. If anything goes wrong, the online gambling regulator doesn’t usually get involved. It’s usually us that needs to step in. That said, KoiCasino hasn’t given us any reasons to worry about their operation.

KoiCasino recently obtained Estonian license and now is accepting players from Estonia, including Pay N Play feature.

Unfortunately, there is a long list of excluded countries at KoiCasino. This includes:

Afghanistan, Australia, Belgium, Cambodia, France, Ghana, Greece, Greenland, Hong Kong, Israel, Italy, Jordan, Niger, Pakistan, Oman, South Georgia, Switzerland, Spain, Slovakia, Turkey, Tunisia, Uganda, United Kingdom, United States of America, Vanuatu, and the Virgin Islands. The complete list is vast and begs the question of which countries are accepted at KoiCasino.

Complaints and Track Record

KoiCasino does not have any posts referring to its casino in the our forum yet. As a new online casino, this isn’t surprising. If and when the online casino does start to generate player posts in the forum, this review will be updated, and the posts will be added here.

We have zero PABs submitted.
