Development of Koi Casino

Founded in 2021, the casino is quite a new player in the online gambling market. Despite this, it has rapidly grown in popularity thanks to its unique bonuses and impressive collection of slots. It's also one of the few online casinos to accept payments in multiple cryptocurrencies.

The site was created by a group of industry veterans with the goal of creating an easy-to-use online casino. Currently, Koi Casino isn’t available in the US, UK, New Zealand, Australia, Ireland, or the UAE.

Available Games

Koi Casino game selection includes everything from video poker to blackjack variants. The expansive slots catalogue offers an impressive variety of titles from famed studios. You can easily find exactly what you’re looking for thanks to the clean and simple games lobby.


The slots collection is the site’s main draw, with hundreds of options available for every preference. Many of the top software suppliers are featured, including big names like Microgaming and iSoftBet. You can easily filter by the provider to find games from your favourite company. Some of the most famous slots we found were Bonanza and Wolf Gold.

Table Games

If you enjoy blackjack, then Koi Casino’s table games section is for you. Currently, the site features two variants of this classic game. These include Blackjack Neo and Blackjack Royal Pairs.

Scratch Cards

There are no scratch card options at Koi Casino.

Live Casino

As a new casino, the site doesn’t currently offer live games.


There was no sportsbook section available. Koi Casino specialises in providing games like slots, blackjack, and roulette. Unlike other sites that try to combine sports and casino sections together, this site focuses on one option to provide a high-quality online casino.

Koi Casino for Mobile Devices

With new games and promotions being released all the time, it can be easy to miss out on the latest features from Koi Casino. The site’s mobile version offers an excellent way to enjoy the casino’s best games on the go. It’s fully optimised for mobile devices and includes all the site’s primary features, letting you withdraw and deposit from anywhere.

Customer Support

Koi Casino features an FAQ section where you can find solutions to some of the most common issues. These are helpfully grouped into the categories of Getting started, Verify my account, Bonus and Free Spins, and Banking.

If you have a more significant problem, then you can get in touch with the site’s helpful customer support team. You can easily find a link to the contact form at the bottom of any page. Here you’ll need to enter your name, email, and inquiry so support can contact you with a solution. 

You can also choose to speak directly with a support team member over live chat. Like with the form, you’ll need to enter your details and wait for a response. 

Trustworthiness of Koi Casino

We are happy to confirm that Koi Casino is 100% legal with many trusted affiliations. The site features industry-standard SSL encryption. This security technology secures all transactions that flow between you and the site.

Third parties will find it difficult to intercept and steal your personal and financial information. All games are also RNG certified, meaning they are guaranteed to be fair and always produce randomly generated results.

Koi Casino License

The site is owned by investment company Njord Ventures BV. It holds an official license from Curaçao eGaming to provide online gambling services. This license holds the site to strict regulations and ensures a secure and fair gambling experience. 

Problems with Koi Casino

One of the main problems is that the site isn’t available in some major countries like the US and UK. This can lead to many players being blocked from accessing the casino.

Since the selection of games largely consists of slots, those looking specifically for table games have fewer potions. While the most popular games like blackjack are available, lots of more niche titles like baccarat are not.

Koi Casino is an excellent site that provides fast services and an impressive number of slots. Thanks to the speedy deposit and withdrawal times, our gameplay experience was never interrupted for long. The site featured all the standard encryption and fairness certifications, along with official licenses that ensured our safety.

Players looking for slots will appreciate the expansive selection that includes many famous titles. The unique cashback bonus granted constant rewards just for playing, and the multiple accepted cryptocurrencies made it stand out from the competition.
