Koi Casino Bonuses and Promotions

The Koi Casino welcome bonus is very simple - it’s a 100% match deposit bonus up to €500, when you make you first fund your account. You can use your first deposit bonus money on the majority of slots, with a few exceptions (including jackpot games).

The maximum bet with an active bonus is €5, and you’ll need to meet wagering requirements of 25x within seven days or you’ll lose the chance of any bonus amount. The wagering is quite low compared to casino bonuses at other online casinos, so it’s definitely an offer worth claiming.

Outside of the welcome bonus, you can visit the Promotions section to find what other offers are available to you. These include an exciting cashback bonus where you can claim up to 15% back on losses daily and free spins on Tuesdays, Thursdays and Fridays with a €1,100 prize pool up for grabs.

Koi Casino Live Casino Bonus

Koi Casino doesn’t have a specific bonus for live casino players, and unfortunately if you claim the main casino bonus, you won’t be able to use the funds on live dealer games.

If you head over to the Promotions section, you’re sure to find some offers that appeal to you. For example, the provider Pragmatic Play often runs Drops & Wins competitions, where you could take home huge wins on live casino games.

Koi Casino Sports Bonus

Koi Casino doesn’t have a sports book offering, so you won’t find any sports promotions here. You’re unlikely to miss it though, given how strong the casino offering is.

Koi Casino Bingo Bonus

While we’d love to see bingo added at some point in the future, Koi Casino doesn’t currently have any bingo games. For now, you’ll have to stick to slots, table games and live dealer games.

Koi Casino VIP Programme

Koi Casino doesn’t have a VIP programme at the moment, but they do offer frequent promotions for all active players, which you’ll find in the Promotions section. The excellent customer support also makes everyone feel like a VIP!

Koi Casino Safety

One of the most important factors to consider when choosing an online casino is just how safe and secure you’ll be. The good news is that Koi Casino is reputable! It hold its licence in Curacao, with the licence number 8048/JAZ. This means that it needs to adhere to certain protocols and regulations to keep you safe.

The Koi Casino website is SSL Secure, which means that they make use of encryption technology to protect you. You can rest assured that both your personal data and your funds are protected when you play here.

You’ll also notice that Koi Casino is RNG Certified. The game studios that it works with all ensure that their games are strictly audited and tested before they’re released to the player. RNG (random number generator) technology is used in all slot games so that each and every spin has a random outcome and the same chance of a win, so players can enjoy a fair gambling experience.

If you need any help while you’re playing, you can get in touch with the customer support team at Koi Casino via email, live chat or by completing the contact form on the website. The team are around 24/7, and in our experience they are efficient and always happy to help. There’s also an FAQ section that isn’t totally comprehensive, but can be useful nonetheless.

Online gambling services that promote responsible play are also very important to ensure a safe experience. Koi Casino provide online gambling services at the footer of the website, and you can read the full policy, plus find information on external organisations which can support you. You can get in touch with the customer service team if you’d like to self-exclude, but aside from this there aren’t many responsible gambling tools available.

Koi Casino Game Selection

The Koi Casino games selection is what sets it apart from much of its competition. You can choose from hundreds of different slots, dozens of live table and virtual table games, and even some card games, all from an almost endless variety of top-quality software providers.

No matter what kind of games you’re in the market for, you’re certain to find them at Koi Casino.

Table Games

Koi Casino offers a good selection of around 10 different card and table games, from a number of casino software providers like Games Global, Relax Gaming and EGT. These include popular games like roulette, blackjack and baccarat.


Koi Casino works with dozens of different game studios to bring you the very best selection of bonus slots. You can explore games from top casino game providers like Pragmatic Play and Quickspin, but we’d also recommend having a go at titles from the likes of Gamomat, Fantasma and BGaming.

At Koi, you’ll find top videos slots like Fruit Party, Temple Tumble and Sweet Bonanza, alongside brand new additions like USA Flip and Lucky Twins. There are tons of different themes like Ancient Egypt with slots like Alexandria Fire and John Hunter and the Book of Tut Respin, plus sports-themed slots like Hockey League and Spin & Score and fruit machine slots like Starlite Fruits: Mega Moolah.

Megaways slots are popular here too, and these are always fun because your ways to win change all the time. Have a go at a game like 5 Lions Megaways or Twin Spin Megaways. 

Bonus buy games are also available here, which is always great to see at an online casino. These games give you the option to purchase your way into the bonus round, which can be the most exciting part of a slot game. 

All the slots allow you to choose your stake, with spins generally ranging from around 20c to anywhere between €20 and €100.

Live Dealer Games

The live dealer games at Koi Casino come from Evolution Gaming, Pragmatic Play, and OnAir Entertainment, so there’s no shortage of choice or quality. While you’ll see some of the popular games when you land on the live casino page, to view the full live game selection, you’ll need to enter the lobby for each provider. There are dozens of tables, so even at the busiest times you’ll find a place to play.

The main games on offer are the casino classics like roulette, blackjack, baccarat and poker online, but there’s also an excellent selection of fun game shows like Monopoly Live, Crazy Time and Dream Catcher. Evolution Gaming also has a “First Person” selection of games, which combine animation with the live dealer experience.

You can customise your stakes to suit your own preferences, for example, you can play at some roulette tables for as little as 10c per spin, while you can play blackjack for as much as €5,000 a go.

Koi Casino Review in Summary

Koi Casino provides an excellent experience from start to finish, so we are happy to recommend it as a great place for Irish players to enjoy casino games. The stand-out here is the slots selection, although the live dealer games are impressive too.

When it comes to signing up for your account, you’ll just need to give some basic details like your name, email address, date of birth, home address and mobile number, and you’ll be ready to start playing before you know it.

The next thing to do is to fund your account. You can do so using traditional deposit methods like your Visa or Mastercard debit card, while Koi is also among the top Paypal casinos, among many other e-wallet payment options. Alternatively use a cryptocurrency like Bitcoin, Litecoin or Ethereum. Deposit limits vary per banking method, but most of them have a minimum deposit of €25 and have a maximum deposit of €10,000. Some methods incur a small fee, but it’s usually only €1. Casino withdrawals require a minimum of €25, which is quite high compared to the usual €10.

On the games page, we were impressed to see just how easy it is to navigate the huge range of slots. You can view popular titles, new games, bonus buy games, or other categories like high volatility games or sports-themed games. You can also view all games from a certain casino game software provider, or search by name. 

As you’d expect, Koi Casino also provides a decent mobile experience. There’s no app, but you can play using your favourite mobile browser, and you can enjoy all the features of the desktop site, including deposits and withdrawals, claiming offers, and of course playing the games. Games are built using HTML5, which means they work perfectly on your smaller screen – everything from the visuals to the speed of gameplay is flawless.

There are a few things we’d like to see Koi Casino add in the future, for example a VIP offer or the chance to play free slots, but for now there’s plenty to enjoy when you play there!
