Koi Casino Review

Koi Casino launched in 2021 with a Japanese koi theme. Despite its youth, it already works with well-known studios, accepts crypto and offers strong cashback.

Koi operates under a Curaçao licence. It is not licensed in the UK.

New players get a deposit match. In our records, wagering was 25x the deposit plus bonus. Current offers are listed on this page.

Cashback of 15% had 10x wagering in our records.

The library includes games from NetEnt, Microgaming, Big Time Gaming, Pragmatic Play, Nolimit City, Red Tiger, Relax Gaming and Thunderkick, with live games from Evolution.

Methods include Visa, Mastercard and Bitcoin. The minimum withdrawal is €100; limits are otherwise reasonable.

The lobby is designed to be convenient on any device.

Live chat is open 24/7.

Koi suits crypto players in accepted markets who want fair wagering and cashback.

Koi Casino is licensed in Curaçao, not by the UK Gambling Commission. That means it is not authorised to offer gambling to players in Great Britain, and UK players do not get UK protections such as GAMSTOP, strict affordability checks or the UK’s complaint and dispute rules.

If you live in the UK, choose a UKGC-licensed casino instead – see our best UK casinos. If you live elsewhere, check that online casino play is legal where you are before you sign up.

Signing up at Koi Casino is quick, but verification usually happens later than at UK-licensed sites:

1. Click Sign up and enter your email, a password, your name, date of birth and address.
2. Choose your currency – including crypto, where available – and enter a bonus code if the offer requires one.
3. Make your first deposit.
4. Before your first withdrawal, expect to upload ID, proof of address and sometimes proof of payment. Doing this early avoids long delays when you want to cash out.

Example: deposit €100 and get €100 bonus. At 25x deposit plus bonus, you need €5,000 of bets.

Offers change regularly, so always check the current terms on the casino site before you deposit.

Casinos without a UK licence are not part of the UK’s GAMSTOP scheme, so the tools available depend on the operator and its regulator. At Koi Casino, ask support to set deposit limits or to close or self-exclude your account if you need a break. You can also use blocking software on your devices and your bank’s gambling block.

Free, confidential help is available wherever you are – for example Gambling Help Online in Australia (1800 858 858) or the National Gambling Helpline in the UK (0808 8020 133). Read more in our guide to gambling harm.

• Roku – another Japanese-themed casino.
• Maneki – a lucky-cat casino.
• Royal Rabbit – fair wagering.

Our overall score for Koi Casino is 4.4 out of 5. It is based on four areas we check for every casino:

We also look at customer support, mobile play and the fairness of terms. Scores are reviewed when casinos change their offers or services.

Withdrawal times are typical ranges after the casino has approved your request, and can vary with verification and your bank. Prepaid vouchers such as Paysafecard usually cannot be used to withdraw, so you will need another method to cash out. Compare methods in our casino payments guide.

Koi has fair wagering and solid cashback. The €100 minimum withdrawal and limited payment methods are the drawbacks.
