Koi Casino Review – free spins, welcome bonus, cashback

Register and Play Here

Koi Casino is a fresh and modern Japanese-themed instant play casino with no registration required. Payments are handled conveniently with fast banking services, and as a treat, you can expect daily cashback.


Koi Casino, one of the new casinos of 2021, aims to be a clean and fair gaming site “without nonsense and unnecessary adjustments”. The ingredients for this are excellent, with Koi Casino's fresh site being sleekly modern in style and superbly easy to use. What's more, access to play, deposit and withdrawal is made as easy and straightforward as possible, as this is a no-registration casino. This means that authentication and money transfers are a snap with just your bank account details.

Koi Casino's offering of over 1,000 games focuses heavily on slots, including Megaways and jackpots. There is also a live casino offering quality entertainment, and table games and video poker are apparently on the way.

Welcome bonuses are still one of the main attractions of online casinos for many players, and Koi Casino has taken this into account. There is a 100% up to €500 bonus for new players, plus a 15% daily cashback. On the promotions page, you can also spot other offers and tournaments with great prizes.

Koi Casino is run by Njord Ventures B.V., which operates out of Cyprus and Curacao. The casino is licensed in Curacao (8048/JAZ), so net winnings count as taxable income from players in Europe. It is also worth mentioning that the same company also manages Buumi Casino, which we also reviewed.

As you continue to take advantage of Koi Casino's other bonus benefits, it's worth bearing in mind that free spins winnings are also subject to a 50x wagering requirement, but you only have 24 hours to complete it. A similar short wagering period also applies to free bonuses. To claim free spins with a deposit, you need to wager the amount deposited five times.

Layout, Theme and Usability

Koi Casino's name refers to the Far East, and in Japanese the word koi means love. However, the look and feel of Koi Casino is fresh and modern, with an elegant simplicity rather than an oriental or romantic feel. Orange and white have been chosen as the main colours, with the odd touch of gold here and there to add a refreshing touch of extra sparkle. Visually, the whole works perfectly and makes a pleasant first impression.

Koi Casino's site is easy to navigate and plays very smoothly on both computer and mobile. All the most relevant content texts, including the general bonus terms and conditions and the FAQ section, have been translated and localised into many languages, and navigation is effortless. You'll need English skills if you want to familiarise yourself with the general terms and conditions, cookie policies, verification document instructions, etc.

Koi Casino Games

Koi Casino's selection of over 1,000 casino games is, at least for now, heavily weighted towards slots, including jackpot slots of course. A small but high-quality collection of live casino games and a few table games are also covered. There is also a category for video poker, but at least for now it still seems empty. Of course, this could change very soon.

In any case, the initial situation in terms of game offerings looks promising, especially as Koi Casino will be shaking down a list of the gaming providers it has partnered with. The impressive litany includes brands such as:

Also, it's good to know that the casino's games can be filtered by gaming software (developer).

Tapping on “Favourite games in your area” will bring up a host of familiar slots such as Book of Vikings, Sweet Bonanza, Money Train 2, Great Rhino Megaways and Fortune Reels. There are also themed collections of slots such as Slots with a Buy-in Bonus and Drops & Wins slots.

The progressive jackpot offerings at Koi Casino remain a little obscure, as there is unfortunately no category for jackpots. At least NetEnt's popular jackpot games seem to be missing at the time of writing, and there are no Microsoft millionaire jackpots either. A word search for jackpots returns the only game that comes up is Rainbow Jackpots. No doubt, however, there are jackpot games lurking among the slots, if you can only dig them up.

In terms of virtual table games, Koi Casino only offers a couple of blackjack versions in the early stages. The live casino tables, on the other hand, are much more varied. In addition to blackjack, you can play variations of roulette, Dragon Tiger and game show games such as Mega Wheel and Crazy Time, all in real time and under the guidance of real dealers working in the studio.
