Review of Koi Casino

Koi Casino’s Japanese design and clear nod to the popular Koi fish is the first thing that strikes us when we enter this site. Exactly what the theme has to do with gambling we’re not sure, but if there’s a goldfish in the pond 🦐 we can understand it. Anyway, Koi Casino offers bait in the form of a standard welcome bonus of 100% up to €500. Let’s dive into the fish pond and see what’s hiding there.

Koi Casino Welcome Bonus and Terms

The welcome bonus here at Koi Casino is of a normal Sticky bonus nature, and you use the bonus money only before the deposit.

First deposit

100% up to €500

Turnover requirements

On this 100% welcome bonus, 25x (d+b) must be wagered. It simply means that both the deposit and the bonus money must go to pers. Since it is a 100% bonus it means exactly the same as 50x wager only on bonus money received.

You have 7 days to complete the turnover, and only slots in the casino count for this purpose. A list of slot machines that cannot be used for turnover can be found in the bonus terms at Koi Casino. You yourself are responsible for checking this before you start playing.

Max bet

The standard max bet of €50 is the rule here at Koi Casino, and since it is a sticky bonus, this applies from the first spin. Your deposit and the bonus money are ‘mixed’ in the same pot, and you cannot buy bonuses or go bananas with the stakes until the turnover requirement is met.

Free spins

Koi Casino does not have free spins on the program when they invite to a party. And when we think about it, is free spins in a welcome offer perhaps a bit exaggerated? Especially if they come with a low value and a high turnover requirement. If, on the other hand, you get free spins without turnover of good value, then we are talking about an interesting offer.

Other promotions at Koi Casino

The promotions section here at Koi Casino is not exactly overflowing with other promotions, but as you know, quality is better than quantity. Here is what we note.

  • Up to 15% cashback: The day after you have made your first qualifying deposit, you will receive an email with an offer for a cashback campaign. You must deposit a minimum of €50 to participate, and be sure to read the campaign terms in the email you receive,
  • A free spin: Anyone who has made a deposit within the last 30 days at Koi Casino will receive 1 free spin every Tuesday, Thursday and Friday. The competition is about winning the most on one spin, and the first prize is a whopping €500


We do not find any loyalty program here at Koi Casino. We have already found that this casino likes it simple and uncomplicated. Insert and play, without being showered with things and pliers. If, on the other hand, you are someone who likes extra excitement, you can benefit from checking out our casino offers and VIP-Casino pages. Here there is a little bit of everything for every taste..

Payment methods

We appreciate the varied selection of payment methods here at Koi Casino. Visa and Mastercard are of course regulars, in addition to two good e-Wallets in MiFInity and Jeton Wallet . We are particularly happy with Jeton, as it is a very good service that we unfortunately see far too little of at our favorite casinos. Crypto is also available here, and we observe an ever-increasing popularity among players to use precisely crypto-currency to play online.


Koi Casino has high withdrawal limits of €1000 per day. Of course, you may find that certain payment methods are limited to a lower sum per transaction, but then you just have to split the withdrawal into several shipments. Remember that the current rules state that the method you used for deposits must also be used for withdrawals.

Games and game developers

We actually think that Koi Casino has a very acceptable selection of slots and game developers. We count 66 different providers, and here there are many audience favourites. Although we find Gamomat here, we are a little disappointed with the selection. They could have benefited from a few more Gamomat titles. If we have to mention another popular provider that we miss, it has to be ELK Studios . Otherwise, we’re pretty sure you’ll find what you’re looking for here.

Live Casino / table games

This is one of the few casinos we have reviewed that does not offer Evolution Gaming in the live casino. It is actually quite rare, but don’t worry. They of course have Pragmatic Live games, and another fairly new provider that is experiencing increasing popularity. We are talking about OnAir Entertainment with its popular Streamicon version of 9 Pots of Gold. It has become mega-popular in a short time, and we recommend you check it out.

Customer service

A translation function is in place, so you can write in any language without problem. We can’t find any timetable for opening times, but we understand that there is probably not 24/7 coverage on live support. Although we can’t say for sure.

Design and ease of use at Koi Casino

As we pointed out earlier, this page is simple and straightforward to use. Little disturbing elements, and very clear. We easily find what we are looking for, and search menus are in place. We also have a sense for the actual design and color scheme here. It is simply an appealing site.


Even if you will not find a menu for uploading documents after you have registered here, this does not mean that you are exempt from verification. Talk to live support, or send an email to customer service to request activation of KYC. If you don’t do that, any withdrawal will take longer, because they will ask for the documents then.


It is Njord Ventures BV, with a Curacao license, that is behind the operation of Koi Casino. We know from the name that this is of Scandinavian origin, and quite rightly they have their origins in Sweden. They also have another casino in operation called Buumi.

Overall impression Koi Casino

Koi Casino is not new. They have been in business for a couple of years already, and we have great faith that they have managed to overcome all childhood illnesses that naturally come with starting an online casino from scratch. Those who like it simple will thrive here, and of course a good bonus of 100% up to €500 is a great incentive to test out Koi Casino. We have seen lower turnover requirements, but we have seen much higher as well. So, all in all, in the middle of the tree. Let’s hope that Koi Casino can impress our readers. As I said, we have good faith!
