Koi Casino Welcome Bonuses

  • 100% up to €500 on 1st deposit

They offer a fairly common welcome bonus. Not that we're complaining. We are always happy with a 100% deposit bonus, and €500 is not a bad amount to double. Previously, they had a cashback as a welcome package, and everyone who reads reviews here knows that we are not very happy with cashback as a welcome bonus.

Unfortunately, we did not find any free spins on the online casino's website, nor anything by email. Rare stuff. Yes, as you have probably already guessed, you do not get any free spins. Not in the welcome bonus, not with the help of further promotions. Why the online casino has chosen to do so is difficult to say.

Regular Bonuses and Promotions 

The casino has these promotions ongoing at the time of writing:


Yes, fortunately, you do not get cashback on your first deposit anymore – this seems to be a regular campaign, where you get a share of your money back all the time. Unfortunately, they have not posted much information, so it is difficult to say exactly how everything works. You will be notified of “up to 15% in cashback“, but it is unknown in which cases, how often and what sums are involved.


At the moment, there is only one extra campaign in addition to the cashback bonus, but this is a good sign anyway. Koi Casino will thus launch various casino tournaments that are managed by large, well-known game developers! The principle is exactly the same as in regular tournaments, ie you play designated machines and rake in points to climb up the leaderboard.

First Deposit Bonus

Koi Casino Game Collection 

  • Number of games: 2,000+
  • Type of game: Slots, Table Games, Live Casino

Leaving aside low bonuses and a generally boring design, they actually have a pretty stylish overview of casino games. Here you will be greeted by large, rich images and several smart, user-friendly shortcuts that help you find your way around. Of course, the portfolio is dominated by wheel games, but you can also try your hand at digital table games or live casino.

At the top of the screen you see the main menu, where you can choose between classic slot machines, video slot machines and other cash games. The homepage can also guide you straight to newly launched games and the most popular titles. Quite flexible! In addition, you will see a filter, where you either search for your favorites, sort the games according to your own wishes or choose a suitable supplier. Well done!


They could lift the experience another notch with the help of thematic collections, as they have done with e.g. Rizk Casino. Why can't you jump straight to Egypt-inspired slot machines, or slot machines with a focus on Japan? Koi Casino has obviously been inspired by the Japanese fish, so how about building on this?

Instead, you have to rummage around in the crowd, or choose a certain game developer in the menu. Unfortunately, not many of them are available – Pragmatic Play, Microgaming, iSoftBet, Relax Gaming and Big Time Gaming are what await you right now. So we miss both certain popular suppliers like NetEnt and lesser known names like ELK Studios. Most likely they will include these in the future when the online casino has got a little extra fertile ground.

Table Games

If you feel like playing table games, you should probably wait a bit – until the online casino has set the pace and expanded its game selection. When we wanted to take a closer look at the table games, we found only two titles! Yep, two blackjack games from Relax and iSoftBet, that was it. No roulette games, baccarat or the like.

Here, too, we think that Koi Casino will work hard in the time to come, but we do not understand why this was not done before. In addition, we miss both scratch cards, digital bingo, and other alternative money games that people love to enjoy from time to time.

Live Casino

Unlike most other players out there, they have chosen to only work with Pragmatic Play when it comes to live casino. At least now in the first place. Here we are talking about lesser-known games, but certainly not worse than the competition. Choose between blackjack and roulette, or go straight to the colorful Mega Wheel, which is the equivalent of Dream Catcher from Evolution Gaming!

Not the largest selection we have seen, and if you are already a big fan of online live casino, you will probably miss several games – Monopoly Live, among others. If, on the other hand, you are completely new to this part of the casino universe, it can actually be a plus to have smaller titles to choose from. Try your hand at your own pace and see if you like the experience!

New Slot Games

Koi Casino Mobile and App

They have no mobile app that needs to be downloaded to play casino on their mobile – instead you just visit the website from your favorite device and log in as usual. All modern casinos do it this way, and you will of course be greeted by a special, customized version of their website. Here it is actually an advantage to have such a simple design. The usability of mobile phones and tablets is brilliant, and you can even make deposits while out and about! Countless people actually prefer to play casino on mobile devices, so why not try it out the next time you wait for the bus or get bored in the bathtub?

Koi Casino Payment Solutions 

  • Minimum deposit: 10 EUR
  • Deposit and withdrawal methods: Bitcoin, Bitcoin Cash, Ethereum, Paysafe, Ecopayz, Instant bank transfer, Interac, Klarna, Litecoin, MasterCard, Visa, Bank Wire
  • Withdrawal time: 0-48 hours

If you live in any European country, Canada or New Zealand, you will never have trouble making a deposit at Koi Casino. Credit cards, e-wallets, bank transfers – everything works brilliantly and lightning fast. In addition, players of Koi Casino can pay and play with popular cryptocurrencies.

Withdrawals are made in the same way as deposits, and if there are problems, the casino can send you the winnings via a bank transfer. Nothing to complain about here. The actual processing of the withdrawal takes a maximum of two days, as long as you have met all the rules and conditions. Play, enjoy yourself, win money, and use the winnings as you wish!

Koi Casino Customer Service 

  • Contact methods: Live Chat, Email ([email protected])
  • Support languages: English, French, German, Finnish, Polish, Norwegian

If you need help or have questions, just tap the word “Chat” in the lower-left corner of the screen. A little strange that the online casino has avoided the usual speech bubble that signals this contact method. Otherwise, you can also press “Contact us” in the bottom menu, to see a contact form. Describe the problem and send it in, and you will be contacted as soon as possible with an answer.

By the way, remember to drop by the FAQ section before contacting customer service. There you can find answers to many common questions, despite the fact that the overview itself is not very rich in content.

Koi Casino Licence and Ownership 

  • Ownership: Njord Ventures B.V.
  • Licence: 8048/JAZ by Antillephone

As you may see from the name (“B.V.” at the end), Koi Casino is owned by a Curacao-registered company. Something unfortunate, since they are thus sitting on a cheap casino license from the local authorities in the Caribbean country – not very strict supervisory authorities, to say the least.

By the way, This company is also famous for having another casino called Buumi. As we managed to check, this brand is popular among players and collects good opinions. So it is a sign of goodness.

User Experience / Interface

As soon as you visit the website, you will see that the website is quite simple, with clear menus and shortcuts to most things. Thus, the user-friendliness is very high, despite the fact that some experienced players will probably miss more information and more details. The registration is done in about a minute. And, the moment after you can make a quick and easy deposit using the flexible payment methods. Our user experience was exclusively positive. We liked that you get access to brand new wheel games and a separate list of “top games in your area”.

Incredibly fun to see what other casino players prefer to enjoy! A little further down you will see some important points about why one should play at Koi Casino, as well as a reminder of their cashback scheme. The company behind the scenes has obviously focused on the convenience of users – we just hope that they continue to keep the online casino up to date and to modern standards.

Responsible Gaming Tools 

Fortunately, they have a fairly extensive section that is about responsible gaming, so it seems that they actually care about the players' well-being. Good sign! Once you have registered your account, you will be offered to activate deposit limits or loss limits, two flexible tools that both deserve to be considered. We may actually recommend activating both, according to your predetermined budget. It's easy to forget when you're having fun, so such player tools can be incredibly smart.

We could have imagined a few more boundaries, in addition to so-called session reminders, but the player will still have his thumbs up for his tools. The authorities in Curacao do not require this from their licensees, unlike the MGA license.

Koi Casino Final Verdict

Koi Casino may be one of the new kids on the block, but it meets all the requirements we find crucial to recommend a casino. The bonuses are few, but at least they have a solid welcome bonus. Ease of use is nothing special, although everything works fine and is adapted to mobile use. A professional and ambitious team works day and night to ensure all players are happy. We believe it will go far and keep working to make your experience better and better. Go see for yourself. It's worth it.
