Is there a welcome bonus for September 2025?

There doesn’t appear to be a standard Koi Casino bonus for new players, but there are three notable promotions on offer that are all rewarding and have a number of perks that we will go into further detail below:

Other bonuses for new and existing players

The best bonus casinos will have a wide range of deals to choose from for new and existing players. Koi Casino offers a huge range of promotions:

🎁 Bonuses offered	💝 Bonus offer	🎲 Wagering	💸 Min deposit	⌛ Time frame
Spin and Win	One free spin every Tuesday, Thursday and Friday, with cash prizes	20x on prizes won and the free spin	€20 within the last 30 days	7 days to use the wagering requirements
Drops & Wins	Compete for over 50,000 prizes every week	N/A	€0.15	Promotion runs until 19th November 2025
Daily Cashback	Get up to 15% cashback daily.	10x (x50 from free spins)	€5	Within 1 day

Welcome bonus for UK players

As Koi Casino isn’t available in the UK, there aren’t any UK specific offers available.

Welcome bonus for Canada players

There are no welcome offers exclusively for Canadian players at Koi Casino. We’d love to see some in the future - we’ll update this page if they do, so make sure to check back every now and then.

Koi Casino no deposit bonus

There didn’t seem to be any deposit bonuses at Koi Casino, but this may change in the future, so it’s worth checking their promotions page for any updates.

Koi Casino cashback bonus

Koi Casino has a 15% daily cashback scheme - all you need to do is deposit, play, and gain automatic cashback based on your playing activity. The minimum deposit amount is €5 and the wagering requirements are 10x. Cashback and bonuses are valid until 23:59 local time on the day they are issued and the wagering must be completed within one day.

VIP member bonus

Koi Casino doesn’t have a VIP or loyalty programme, so for regular players who love reward based systems or climbing tiers, this might be disappointing. Casinos use VIP schemes to reward consistent play with perks like higher withdrawal limits, personal account managers, or exclusive event invitations. Koi might want to consider adding this in the future, as it will encourage repeat visits and increase customer loyalty.

How safe & trustworthy is Koi Casino?

Casinos with a strong reputation for safety are essential, so we reviewed Koi Casino’s protections in detail.

Safety and security - Checked on September 4, 2025

Using our tried and tested methods, we have given Koi Casino a safety rating of 7.4. When producing this score, we take several factors into account. 

The first thing to consider is the licensing, with Koi Casino fully licensed in Curaçao. That particular licence is fully legitimate, meaning you are in safe hands on this front. The site has the relevant SSL and RNG certifications, ensuring that you are playing at a safe and legitimate site. 

We take a look at the terms and conditions, noting how accessible they are and how easy they are to understand. Koi Casino has a clear link to its terms at the footer of the site and they are well presented and easy to understand. 

The casino struggles with its offering of responsible gambling tools, where we could only find the ability to close your account. We will provide further details later in the review, but we feel that more tools could be provided to improve the score. Doing so would help bump our safety rating up closer to a maximum five. 

KYC and withdrawal – Checked on September 4, 2025

Koi Casino aims to complete its KYC (Know Your Customer) checks within 48 hours of you submitting your documentation, and will notify you by email when it’s completed. 

To verify your bank details, you will need to provide a document such as a bank statement or a page from your online banking from the last six months. 

If using an e-wallet, you will need to provide an image that includes your name and email address, matching the one you registered with.

When verifying your debit or credit card, you will need to send an image of the front of your card, but you may block out the middle eight digits for security reasons.

All players will need to verify an address using either a utility bill or a bank statement from the last six months.

What other players and reviewers say - Updated on September 4, 2025

Koi Casino’s reviews are a little mixed. Here’s what we found at both ends of the spectrum:

Games at Koi Casino

Some of the best online casinos available right now will have a diverse range of games in their library. Here are some examples of slots games that are popular with Koi Casino players this month:

• Sugar Heaven

• Duck Hunt 500

• Unholy Mystery

• Astro Rumble

• Burning Sun

Is there a wide range of providers available?

There are 13 providers available at Koi Casino and these include:

• Thunderkick

• Quickspin

• No limit City

• Wazdan

• Evolution

• Play‘n GO

• Pragmatic Play

Popular Megaways slots

Megaway Slots have high volatility - which means that there’s the potential for much bigger wins (but fewer payouts) making them a popular choice for slots fans. Here are some Megaways titles that have been a hit with Koi Casino players this month:

• Gonzo’s Quest Megaways

• Play with the Devil Megaways

• Zombie School Megaways

• The Dog House Megaways

• 5 Lions Megaways

Online slots

Here are some slots games that are popular with Koi Casino fans this month:

Book of Dead

Popular slots like Book of Dead are a top choice for slots fans. It’s a game that stands out for its exciting bonus features and mysterious ancient Egyptian theme.

Sweet Bonanza

Sweet Bonanza is a colourful, candy themed slot that has exciting tumbling reels and multipliers, and it’s also known for its high volatility and a thrilling free spins feature.

Gonzo’s Quest

Gonzo’s Quest is a classic that combines adventurous gameplay with cascading wins and a whole host of other interesting surprises.

The Doghouse

The Doghouse is a playful and fast paced slot that’s packed with charming canine companions, sticky wilds, free spins, and plenty of potential for some big wins.

RTP transparency

Koi Casino doesn’t show any RTP percentages on any of their games - so if you want to check the RTP, you can either visit the game developer’s official site, or run a quick search engine check. We think that displaying RTPs would put Koi at an advantage, helping their players make more informed decisions when choosing the right slot game, and building up more trust as a casino brand.

Blackjack

There are 76 blackjack games available and some of them include variations like Privė Lounge Blackjack, Blackjack VIP, Vegas Downtown Blackjack GOLD, and Blackjack Neo. We were impressed with the excellent choice of live blackjack tables, with 39 different choices when we signed in to play. 

Roulette, poker and other table games

For roulette there are 33 games on offer, with titles such as - Roulette Ruby, Extreme Multifire Roulette, Mega Roulette, and Dealers Club Roulette. There’s also a number of casino poker games from Jacks or Better Draw Poker to Hold ‘Em to other table games like Turbo Baccarat and Dice City.

Crash games

There’s no way to filter for crash games on the Koi Casino website. Looking through, we found at least four, including Big Bass Crash, Dragon’s Crash and Speed Crash.

Koi Casino unique features

Koi Casino’s excellent crypto support rivals some of the best online casinos. While KYC documents may take up to 48 hours to process, most report crypto withdrawals being instant. 

Deposit and withdrawal methods

The best online casinos will have a few deposit and withdrawal methods to choose from, so we were disappointed with the lack of options at Koi Casino. 

The site lists Visa and Mastercard debit as an available payment method, but after testing the site we could only see bank transfer as an option, with a range of banks supported. Here is some more information:

❓Method	🪙 Fees	💸 Min Deposit	⏱️ Payout Time
Bank Transfer	N/A*	€1	3-5 working days

*While there are no fees listed on Koi Casino, each bank may add their own individual fees for using their services, so it’s best to check beforehand.

Koi Casino on mobile

While there’s no Koi Casino app available on the app store, they offer a mobile-friendly website that can be accessed via browser. Koi Casino on mobile has mixed reviews, so we ran a few tests and here’s what we found:

Here’s what these graphs mean for you:

Things we liked:

• Does not request geodata or notification permission

• Avoids third party cookies

Things we didn’t like:

• Slower loading speed than on desktop

User experience and site performance

Koi Casino’s desktop website scored 36 out of 100 in a site performance test. It provides a solid user experience on desktop, though loading speeds and the mobile performance leave a lot to be desired.

What we liked

• A modern site with a straightforward interface to navigate.

• The site has interactive features around their promotions and game tiles, making them more appealing.

What we didn’t like

• The search bar function could be improved - as searching for specific games or providers wasn’t easy because it didn’t provide a list or every available title, which was odd.

Customer support

Koi Casino’s customer support is fast, helpful and polite. When we spoke to one of the live chat operators about cryptocurrency support at Koi Casino, they were helpful and our query was resolved in under five minutes. 

Channel	Availability	Response Time	Resolution
💬 Live Chat	24/7	About a minute	Under five minutes for simple questions
✉️ Email	24/7	Within a day	Around 24 hours for more complex issues, complaints and account closure inquiries

Responsible gambling tools at Koi Casino

Koi Casino takes responsible gaming seriously, with a dedicated page that explains how gambling should be a safe and enjoyable activity and not for any other purpose. They’re committed to protecting players and reference a number of tools that are available to help with anyone who is struggling with their gambling. However, they are not very clear about what those tools are. 

Aside from mentioning the option for account closure, the responsible gaming page doesn’t go into detail about the player protection tools, so it would be useful for Koi to explain whether there are deposit limits, or how to self exclude. But if you do run into any issues, we suggest that you contact the customer support team on [email protected], or visit an external organisation for help like Be Gamble Aware.

The verified safer gambling tools available on Koi Casino are:

• Account closure by request

• Links to third-party support organisations
