About Koi Casino Website 

  • Launched in 2021

We tried hard to find out something about Koi Casino, about the people behind the project, and similar information, but unfortunately came across a wall of emptiness. No, Koi Casino is not created by a reputable company – they have no sister sites, no flagships or the like. The online casino is developed and managed by Njord Ventures B.V., with offices in Curacao and Cyprus.

Koi Casino looks pretty good at first glance. Especially if you like bright, clear online casinos. Here you will find no superfluous details or unnecessary images that ruin the whole – only a sparkling, white background and orange menus that create a good contrast. The start page gives you maximum information from the start and we really appreciate it!

Koi Casino Welcome Bonus

Koi Casino offers a fairly common welcome bonus to new players. We like that you get a 100% deposit bonus and that the €500 can be doubled. Prior to this welcome bonus, Koi Casino did not have a welcome pack for new players. So, they have now fixed a bonus we appreciate as we were not completely happy with their previous offer. Below you will easily see what you need to do to get the bonus.

Unfortunately, we did not find any free spins on the online casino, nor did we find any content via email.

Other Bonuses and Rewards

Koi Casino has a promotion section, but this one is pretty empty. Yes, another disappointment that made us stare. What is going on? Have they not managed to come up with some exciting offers? Did not have this clear in advance, before the launch? Or do they think that people should register only because they have a nice design with koi fish in the logo?

15% Cashback Offer

Koi Casino mentions that they will reward your play daily, but this is not entirely true. No, the online casino will reward your losses instead! If you lose a lot of money, they will give you a small patch on the wound the next day. The principle is simple: make a deposit and waste your money at Koi Casino, and you will receive a “surprising” reward by e-mail the next day. Up to 15% in cashback, that is. If you forget to log in, you will lose the opportunity. Fantastic!

Network Promotions

At the time of writing, Koi Casino has also launched a so-called network campaign from Pragmatic Play, ie a casino tournament that takes place with several dozen players at the same time and gives you the opportunity to win a little extra money. Hive yourself over slot machines marked as “Drops & Wins” and play for at least €0.50 per spin, then you can win up to €50,000 in daily prizes, as well as weekly prizes of €500,000. Great campaign, but we do not have Koi Casino to thank for this!

Koi Casino vs Other Casinos

Yep, we chose the two above-mentioned online casinos on purpose. Both have used the same concept as Koi Casino – no welcome bonus, but daily entertainment instead. Whether you win or lose, Nitro and Ultra will release something cool! On top of this, both have followed their theme to the letter, both through the design, the details, the bonuses and the language of the website. Koi Casino has a lot to learn here, because, with such opponents in the competition, they are doomed to lose.

  • Rapid CasinoHere, too, you will miss out on a welcome bonus, but Nitro Casino has instead attracted attention using two things: daily offers and the lack of wagering requirements. Everything should be fast at Nitro Casino, therefore they send out tailor-made promotions every busy day, and you get to keep everything you win!
  • Winz CasinoAnother online casino that has moved away from the usual welcome packages – Ultra Casino, on the other hand, creates headlines with the help of daily draws! Keep an eye on your inbox and activate the perks, whether you win or lose. Something happens every day at Ultra Casino, so you do not get bored. Low turnover requirements are the icing on the cake!

Koi Casino Bonuses vs Other Casino Bonuses

Try this fast, user-friendly online casino today, and you will get an extra delicious welcome bonus that gives you twice as much extra as you deposit yourself. If you deposit a hundred euro, you can immediately play with 2,000 euros and 100 free spins!

Get a juicy sum of bonus money and enjoy a bunch of free spins on some of the most popular slot machines out there! The young player has taken the market by storm, and really deserves your attention. Especially if you like bonus promotions and sky-high usability!

Yes, who can not challenge Koi Casino, when the online casino has no welcome bonus at all? Take a look at our website and you will see 25 recommended, first-class online casinos. Every single one of them has better bonuses than Koi Casino. All as one. Some players even give more than €1,000 on the spot! With this in mind, it is difficult to understand how Koi Casino will fare in the crowded, highly competitive market. Why should a casino game choose them, and not Caxino or Wheelz? The latter gives out 20 free spins completely free upon registration, even!

Koi Casino Games Selection 

Okay, what do you say about going a little away from the bonuses and the whole part of Koi Casino? If we skip to the game selection, things look much brighter! Literally, in fact – we liked the bright and nice design, with clear categories and good, thoughtful shortcuts to different titles. Well done, Koi Casino!

You will be greeted by a two-part menu, with a search engine and list of providers at the top, as well as a submenu with shortcuts to new launches, video slots, video poker, table games and live casino. If you scroll further down, you can press “Top game in your area” – an exciting concept that we have not seen before. The games themselves are also highlighted with large images and clear headings, in addition to the name of the game developer behind them. Two thumbs up!

Slot Machines

The game selection may not be the largest we have seen, but you will find a little over a thousand casino games in all shapes and colors in total. In addition, Koi Casino collaborates with both large and small suppliers – from NetEnt, Pragmatic Play, iSoftBet, Relax Gaming and Big Time Gaming, to Microgaming, Thunderkick, JustForTheWin, Booming Games, 1×2 Gaming, Old Skool, Rabcat and Stormcraft. If you also scroll to the bottom of the page, you can choose games by theme – including “Drops & Wins”, and titles that allow you to buy bonus features.

Other Games 

If you look at other casino games at Koi Casino, you will be somewhat disappointed. The selection of table games is lousy – a small handful of digital titles is all that awaits you. Where are Casino Hold’em and other cool card games? Nor can the online casino boast bingo games, scratch cards or lotteries such as Keno, so you basically have to focus exclusively on video slots and classic slots. This can quickly become tedious in the long run, especially when comparing Koi Casino with other modern online casinos. Just look at Casino Friday and their brilliant selection of games, for example!

Live Dealer 

Finally, the section comes with live casino, where Koi Casino also does not shine in the crowd of competitors. A small advantage is that the player collaborates with both Evolution Gaming and Pragmatic Play, so you have several charming table games to try out live. Here you also see how things have gone in the last rounds, as well as what bet limits apply to each game. Well thought out. Feel free to try the fun Mega Wheel from Pragmatic, which is an imitation of Dream Catcher from Evolution. Compare the two show games and see what you like best, maybe?

Koi Free Spins

Koi Mobile Casino and App 

The biggest advantage of the simple design, of course, is the mobile-friendliness. Koi Casino works great on all possible devices, regardless of the operating system. Of course, you do not need to download any casino app or the like – just visit the online casino directly in the browser on your phone or tablet, and you will see a customized version of the website. Register or log in, make a deposit and play your way!

With hundreds of mobile-friendly casino games, you always have something to enjoy if you now play at Koi Casino the next time you go out. Everything goes quickly and seamlessly, with a quick transition from section to section. We can easily recommend focusing on the jackpot games, as these can make you a multimillionaire on the spot. Think how fun it would have been to take the top prize e.g. Mega Moolah next time you sit on the bus?

Gaming Licence and Security

As mentioned, Koi Casino is headquartered in Curacao, which is why they have also been granted their casino license by the most relaxed regulator in the world. AntillePhone (the company that issues licenses on the Caribbean island) cares very little about the players' well-being, and will hardly help you if you experience serious problems with Koi Casino. Not that it's very likely – the online casino seems to be completely serious, despite a sloppy job with large parts of the website.

The Curacao license at least emphasizes that security is top-notch and that the company has all the legal rough work in place. We, of course, prefer online casinos with an MGA license, but Curacao is a popular alternative that is often used by smaller casinos in the start-up phase.

Koi Casino Payment Options 

A lot of payment solutions are offered on the Koi Casino's website. For deposits, players can choose from Visa, Mastercard, Klarna, Interac, and Instant Bank Transfer. Additionally, the casino features cryptocurrencies such as Bitcoin, Litecoin, Ethereum, and Bitcoin Cash. According to the T&Cs, the minimum deposit amount in the casino is €20, while the maximum amount for a single deposit is €10,000.

As for withdrawals, Koi Casino has to offer Visa, Mastercard, Interac, Klarna, Bank Transfer, Bitcoin, Bitcoin Cash, Litecoin, and Ethereum. The minimum amount here is €100, and transactions can take up to 24 hours to process. Fast withdrawals are always a plus in today's casino industry, so we hope that the player keeps their promises. The maximum daily amount that you can withdraw is €50,000, while the monthly withdrawals are capped at €100,000.

All transactions are free of charge and players can use the following currencies: EUR, CAD, INR, NZD, NOK, YEN, USD, and SEK. Overall, the casino has a 1x wagering requirement on all deposited funds, which is very common. If this is not fulfilled before requesting a payout, they will charge you some fee.

Koi Casino Customer Support 

If you need help with something, you can always contact Koi Casino via their user-friendly live chat. Just one click at the bottom right (where it says chat) on the website, and you will see a small box. Then, enter your question, and you will get an answer shortly. Customer service is not available around the clock, but you can expect to meet a pleasant staff member from early morning until midnight. Every day of the week, of course. Unfortunately, this casino doesn't offer phone support. E-mail ([email protected]), on the other hand, is an alternative, but who bothers to send e-mail when you can chat live?

Before you dive into live chat and make Koi Casino sweat with your questions, it might be a good idea to drop by their FAQ section. Here you will find some easy advice on how to get started and how the payments work – maybe that was exactly what you were wondering? The FAQ is not very comprehensive, and we liked that the category “Casino bonuses” has only one question: “How do I get information about new bonus offers?”, Where the online casino answers that you should easily check your e-mail regularly. How about filling up the campaign section instead, guys?

Koi Casino Pros and Cons 

The advantage of Koi Casino's sky-high usability. The site is easy to navigate and you can get around easily no matter which device you use. So you can play from your mobile while on the go, from your tablet or from your PC. You also get frequent cashback, something we always appreciate. If there is anything that could be improved, it is the game selection. They do not reach the top when it comes to competitors who have over 5,000 casino games to choose from.


  • User friendly
  • Frequent cashback
  • Works on mobile
  • Fast withdrawals
  • Crypto payments


  • Limited game selection
  • Wagering requirements

That's all we know. What is their vision, what are their plans for the future? Will they invest further in Koi Casino and develop the project, or have they switched to something else? Hard to say.
